Aim: In a high proportion of people with recently diagnosed Type 2 diabetes, a short (2-3-month) low-calorie diet is able to restore normal glucose and insulin metabolism. The aim of this study was to determine the feasibility of this approach in Barbados., Methods: Twenty-five individuals with Type 2 diabetes diagnosed within past 6 years, not on insulin, BMI ≥ 27 kg/m 2 were recruited. Hypoglycaemic medication was stopped on commencement of the 8-week liquid (760 calorie) diet. Insulin response was assessed in meal tests at baseline, 8 weeks and 8 months. Semi-structured interviews, analysed thematically, explored participants' experiences. 'Responders' were those with fasting plasma glucose (FPG) < 7 mmol/l at 8 weeks., Results: Ten men and 15 women (mean age 48, range 26-68 years) participated. Mean (sd) BMI was 34.2 kg/m 2 (6.0); FPG 9.2 mmol/l (2.2). Mean weight loss at 8 weeks and 8 months was 10.1 kg [95% confidence interval (CI) 8.1, 12.0] and 8.2 kg (95% CI 5.8, 10.6); FPG was lower by 2.2 mmol/l (95% CI 1.2, 3.2) and 1.7 mmol/l (95% CI 0.8, 2.7) respectively. Nine of 11 (82%) of those who lost ≥ 10 kg were 'responders' compared with 6 of 14 (43%) who lost < 10 kg (P = 0.048). The 30-min insulin increment was higher in responders at baseline and follow-up (P ≤ 0.01). A food culture based on starchy foods and pressures to eat large amounts at social events were among the challenges identified by participants., Conclusions: The feasibility of this approach to weight loss and diabetes remission in a predominantly black population in Barbados was demonstrated., (© 2019 Diabetes UK.)

In response to the epidemic of non-communicable diseases (NCDs) in the Caribbean, the Heads of Government of the Caribbean Community (CARICOM) issued the 2007 Port-of-Spain Declaration, "Uniting to Stop the Epidemic of Chronic Non-communicable Diseases" and declared the second Saturday in September to be "Caribbean Wellness Day" (CWD). CWD is a call-to-action for engaging the population of the Member States in confronting NCDs and their risk factors. This report reviews the genesis, implementation, and institutionalization of CWD in CARICOM and beyond. The study used quantitative and qualitative methods, including 29 surveys, 7 in-depth interviews, and analysis of media content. Data was provided by NCD focal points at the Ministry of Health in 15 CARICOM countries, as well as by 7 non-governmental and 4 private organizations. Branding materials were well received and locally adapted; much of CWD media content originated from organization websites and were not community-based. Events typically focused on physical activity and health screenings and were attended by up to 3 000 participants. Though most were held in city centers, some CWD activities have involved rural and indigenous populations. CWD has become a catalyst for multisectoral engagement and health promotion activities. Inspired by CWD, PAHO initiated "Wellness Week in the Americas," which includes CWD and promotes its tenets across the Region of the Americas. As CWD further develops, consideration should be given to reliable, adequate, and sustainable financing; to measuring and evaluating its impact on NCDs; and to widening its reach to include those outside of city centers., Competing Interests: Conflicts of interest.

Background: Although much work has begun to elucidate contextual factors influencing implementation, the specific processes that facilitate and hinder adoption, implementation, and maintenance of evidence-based interventions (EBIs) in clinical settings remains poorly understood. Intervention Mapping (IM) is a systematic process that facilitates planning and design for dissemination, implementation and maintenance of EBIs in practice. IM has been used to guide the design of many health interventions, focusing on program implementation. Less studied is its use to adapt and scale screening interventions within the healthcare clinic setting. This paper describes the development of an implementation intervention using IM to facilitate the adoption, implementation, and maintenance of an EBI designed to increase mammography adherence in healthcare clinics, the adapted Peace of Mind Program (PMP). Methods: IM framework, Step 5, was used to guide the implementation intervention planning. IM guided identification of specific adoption, implementation, and maintenance performance objectives. We formed an implementation intervention planning group consisting of members of the academic team, our community partner and community health workers (CHWs) with substantial experience working on mammography screening programs in federally qualified health centers (FQHCs) and charity clinics. Results: Results are presented by Intervention Mapping task for Step 5 (Program Implementation Plan). We describe how the consolidated framework for implementation research (CFIR) informed the selection of performance objectives, determinants, methods, and practical applications in the final implementation intervention. Conclusions: This paper provides an example of the use of Intervention Mapping Step 5 and CFIR to create an implementation intervention to support EBI scale up of an evidence-based mammography intervention within a specific setting.

A move towards more compact and climate-resilient cities is being encouraged around the world. As part of these plans, there is a need to manage the potential conflict between increasing urban densities and the extent of tree canopy in cities. Reductions in tree canopy are a major contributor to the urban heat island (UHI) effect, which will act to reduce rather than increase climate resilience in many cities. A systems thinking approach called Collaborative Conceptual Modelling was used to study the interaction between urban infill, tree canopy, and human health in Perth, Australia. The results indicated that under current planning policies and development practices, the behaviour of the system is dominated by the drive towards higher housing densities. While this may result in the attainment of urban infill targets, it is likely to lead to a reduction in tree canopy, higher temperatures, and a decrease in a range of other benefits provided by trees. Recommended actions to overcome this behaviour were determined by the identification of leverage points in the system. These included a shift to a sustainable development paradigm that places greater value on the environmental and social benefits provided by trees and a greater emphasis on a climate-resilient future. Market and legislative mechanisms should be integrated into the city's greening strategy and development plans to ensure the protection of existing trees and the inclusion of new trees on public and private land., Competing Interests: The authors declare no conflict of interest.

Infants whose parents and/or siblings have a history of asthma or allergy may profit from receiving exclusive breastfeeding during the first 6 months of life. This is expected to diminish the chance of developing childhood asthma and/or atopic disease. Ongoing breastfeeding for 6 months seems challenging for many women. An educational program was developed using Intervention Mapping as a logic model to guide development and was found successful in improving breastfeeding rates at 6 months postpartum, improving knowledge and beliefs about breastfeeding for 6 months, after exposure to the program compared to controls. Intervention elements included an evidence- and theory-based booklet addressed during pre- and postnatal home visits by trained assistants. This paper elucidates the inner workings of the program by systematically describing and illustrating the steps for intervention development.

Objective: Theory use may enhance effectiveness of behavioral interventions, yet critics question whether theory-based interventions have been sufficiently scrutinized. This study applied a framework to evaluate theory use in physical activity interventions for breast cancer survivors. The aims were to (1) evaluate theory application intensity and (2) assess the association between extensiveness of theory use and intervention effectiveness., Methods: Studies were previously identified through a systematic search, including only randomized controlled trials published from 2005 to 2013, that addressed physical activity behavior change and studied survivors who were <5 years posttreatment. Eight theory items from Michie and Prestwich's coding framework were selected to calculate theory intensity scores. Studies were classified into three subgroups based on extensiveness of theory use (Level 1 = sparse; Level 2 = moderate; and Level 3 = extensive)., Results: Fourteen randomized controlled trials met search criteria. Most trials used the transtheoretical model ( n = 5) or social cognitive theory ( n = 3). For extensiveness of theory use, 5 studies were classified as Level 1, 4 as Level 2, and 5 as Level 3. Studies in the extensive group (Level 3) had the largest overall effect size ( g = 0.76). Effects were more modest in Level 1 and 2 groups with overall effect sizes of g = 0.28 and g = 0.36, respectively., Conclusions: Theory use is often viewed as essential to behavior change, but theory application varies widely. In this study, there was some evidence to suggest that extensiveness of theory use enhanced intervention effectiveness. However, there is more to learn about how theory can improve interventions for breast cancer survivors.

Background: This paper describes the development and implementation of a program to promote prompt and appropriate care seeking for fever in children under the age of five. Designed as a multicomponent program, the intervention comprises elements to influence the behavior of caregivers of children, Community Health Workers, professional health care providers and the wider community., Methods: Following the six fundamental steps of the Intervention Mapping protocol, we involved relevant stakeholders from the commencement of planning to program end. The IM protocol also recommends various behavior change methods to guide intervention development., Results: The intervention components implemented were successful in achieving program goals. For example, the intervention resulted in the primary outcome of reductions in all-cause mortality of 30% and 44%, among children treated with an antimalarial and those treated with the antimalarial plus an antibiotic respectively. Most Community Health Workers were retained on the program, with an attrition rate of 21.2% over a period of 30 months and the Community Health Workers rate of adherence to performance guidelines was high at 94.6%., Conclusion: We were able to systematically develop a theory- and evidence-based health promotion program based on the Intervention Mapping protocol. This article contributes to the response to recent calls for a more detailed description of the development of interventions and trials. The intervention mapping approach can serve as a guide for others interested in developing community- based health interventions in similar settings.

In this paper, we introduce the Intervention Mapping (IM) taxonomy of behaviour change methods and its potential to be developed into a coding taxonomy. That is, although IM and its taxonomy of behaviour change methods are not in fact new, because IM was originally developed as a tool for intervention development, this potential was not immediately apparent. Second, in explaining the IM taxonomy and defining the relevant constructs, we call attention to the existence of parameters for effectiveness of methods, and explicate the related distinction between theory-based methods and practical applications and the probability that poor translation of methods may lead to erroneous conclusions as to method-effectiveness. Third, we recommend a minimal set of intervention characteristics that may be reported when intervention descriptions and evaluations are published. Specifying these characteristics can greatly enhance the quality of our meta-analyses and other literature syntheses. In conclusion, the dynamics of behaviour change are such that any taxonomy of methods of behaviour change needs to acknowledge the importance of, and provide instruments for dealing with, three conditions for effectiveness for behaviour change methods. For a behaviour change method to be effective: (1) it must target a determinant that predicts behaviour; (2) it must be able to change that determinant; (3) it must be translated into a practical application in a way that preserves the parameters for effectiveness and fits with the target population, culture, and context. Thus, taxonomies of methods of behaviour change must distinguish the specific determinants that are targeted, practical, specific applications, and the theory-based methods they embody. In addition, taxonomies should acknowledge that the lists of behaviour change methods will be used by, and should be used by, intervention developers. Ideally, the taxonomy should be readily usable for this goal; but alternatively, it should be clear how the information in the taxonomy can be used in practice. The IM taxonomy satisfies these requirements, and it would be beneficial if other taxonomies would be extended to also meet these needs.

Background: The World Health Organization recommends community case management of malaria and pneumonia for reduction of under-five mortality in developing countries. Caregivers' perception and understanding of the illness influences the care a sick child receives. Studies in Ghana and elsewhere have routinely shown adequate recognition of malaria by caregivers. Similarly, evidence from Asia and some African countries have shown adequate knowledge on pneumonia. However, in Ghana, little has been documented about community awareness, knowledge, perceptions and management of childhood pneumonia particularly in the Dangme West district. Therefore this formative study was conducted to determine community perceptions of pneumonia for the purpose of informing the design and implementation of context specific health communication strategies to promote early and appropriate care seeking behaviour for childhood pneumonia., Methods: A mixed method approach was adopted. Data were obtained from structured interviews (N = 501) and eight focus group discussions made up of 56 caregivers of under-fives and eight community Key Informants. Descriptive and inference statistics were used for the quantitative data and grounded theory to guide the analysis of the qualitative data., Results: Two-thirds of the respondents had never heard the name pneumonia. Most respondents did not know about the signs and symptoms of pneumonia. For the few who have heard about pneumonia, causes were largely attributed to coming into contact with cold temperature in various forms. Management practices mostly were self-treatment with home remedies and allopathic care., Conclusion: The low awareness and inadequate recognition of pneumonia implies that affected children may not receive prompt and appropriate treatment as their caregivers may misdiagnose the illness. Adequate measures need to be taken to create the needed awareness to improve care seeking behaviour.

Background: Integrated community case management of childhood illnesses is a key strategy to help reduce mortality in children under 5 years; particularly those with difficult access to treatment. However, the success of such strategies depends on community utilization of services. This study assessed community utilization, perceptions and related factors of community health worker services., Methods: Data were gathered from a cross-sectional survey among 562 caregivers and focus group discussions among 84 caregivers. Factors related to utilization of community health workers (CHWs) for management of childhood fevers were analyzed using logistic regression and focus group discussions to explore caregiver perceptions of CHW activities., Results: Utilization of CHWs for management of fever in under-5s was 59.4%. Caregivers who were exposed to the communication intervention were about four times more likely to use the services of the CHWs compared to those who were not exposed (OR 3.79; 95% CI: 2.62-5.49; p<0.001). Farmers were 84% more likely to use CHW services for children sick with fever compared to those who were unemployed (OR 1.84; 95% CI: 1.00-3.39; p=0.05). Caregiver perceptions of the program were generally positive; most caregivers expressed satisfaction with the CHW services, citing prompt treatment, friendliness and free medicines. Male involvement in the CHW program was comparatively low., Conclusions: Dissemination of information among priority groups can enhance utilization of CHW services. Exploring the perspective of both men and women to gain in-depth understanding on their views on male involvement will be useful for planning appropriate strategies to get more males involved in community-based child health programs., (© The Author 2015.

Background: Considerable racial and socio-economic disparities exist in breast cancer. In spite of the existence of numerous evidence-based interventions (EBIs) aimed at reducing breast cancer screening barriers among the underserved, there is a lack of uptake or sub-optimal uptake of EBIs in community and clinical settings. This study evaluates a theoretically based, systematically designed implementation strategy to support adoption and implementation of a patient navigation-based intervention, called Peace of Mind Program (PMP), aimed at improving breast cancer screening among underserved women., Methods/design: The PMP will be offered to federally qualified health centers and charity clinics in the Greater Houston area using a non-randomized stepped wedge design. Due to practical constraints of implementing and adopting in the real-world, randomization of start times and blinding will not be used. Any potential confounding or bias will be controlled in the analysis. Outcomes such as appointment adherence, patient referral to diagnostics, time to diagnostic referral, patient referral to treatment, time to treatment referral, and budget impact of the intervention will be assessed. Assessment of constructs from the consolidated framework for implementation research (CFIR) will be assessed during implementation and at the end of the study (sustainment) from each participating clinic. Data will be analyzed using descriptive statistics (chi-square tests) and generalized estimating equations (GEE)., Discussion: While parallel group randomized controlled trials (RCT) are considered the gold standard for evaluating EBI efficacy, withholding an effective EBI in practice can be both unethical and/or impractical. The stepped wedge design addresses this issue by enabling all clinics to eventually receive the EBI during the study and allowing each clinic to serve as its own control, while maintaining strong internal validity. We expect that the PMP will prove to be a feasible and successful strategy for reducing appointment no-shows in underserved women., Clinical Trials Registration Number: NCT02296177.

Little is known about validity of self-reported mammography surveillance among breast cancer survivors. Most studies have focused on accuracy among healthy, average-risk populations and none have assessed validity by electronic medical record (EMR) extraction method. To assess validity of survivor-reported mammography post-active treatment care, we surveyed all survivors diagnosed 2004-2009 in an academic hospital cancer registry (n = 1441). We used electronic query and manual review to extract EMR data. Concordance, sensitivity, specificity, positive predictive value, and report-to-records ratio were calculated by comparing survivors' self-reports to data from each extraction method. We also assessed average difference in months between mammography dates by source and correlates of concordance. Agreement between the two EMR extraction methods was high (concordance 0.90; kappa 0.70), with electronic query identifying more mammograms. Sensitivity was excellent (0.99) regardless of extraction method; concordance and positive predictive value were good; however, specificity was poor (manual review 0.20, electronic query 0.31). Report-to-records ratios were both over 1 suggesting over-reporting. We observed slight forward telescoping for survivors reporting mammograms 7-12 months prior to survey date. Higher educational attainment and less time since mammogram receipt were associated with greater concordance. Accuracy of survivors' self-reported mammograms was generally high with slight forward telescoping among those recalling their mammograms between 7 and 12 months prior to the survey date. Results are encouraging for clinicians and practitioners relying on survivor reports for surveillance care delivery and as a screening tool for inclusion in interventions promoting adherence to surveillance guidelines.

Objective: To identify the accuracy of diagnosing postpartum diabetes and glucose intolerance using antepartum glycosylated hemoglobin (HbA1c) and fasting glucose values., Study Design: A retrospective Hawaiian cohort of women with gestational diabetes during 2004-2011 were evaluated. Antepartum HbA1c and postpartum 75-g glucose tolerance tests were obtained., Results: An antepartum HbA1c value of ≥6.5% had a 45.7% sensitivity, a 96% specificity and a 40% positive predictive value (PPV) for predicting postpartum diabetes. An antepartum HbA1c value of ≥6.5% had a 6.6% sensitivity, a 94.2% specificity and a 27% PPV for predicting postpartum impaired glucose tolerance. An antepartum HbA1c value of ≥6.5% had a 10.3% sensitivity, a 95.7% specificity and a 33.3% PPV for predicting postpartum impaired fasting glucoses., Conclusion: We could not demonstrate a clinically useful PPV for diagnosing postpartum diabetes or glucose intolerance using an antepartum elevated HbA1c value of ≥6.5% or a fasting glucose level of ≥90 mg/dL.

Research has shown that recent post-treatment breast cancer survivors face significant challenges around physical activity as they transition to recovery. This review examined randomized controlled trials targeting physical activity behavior change in breast cancer survivors <5 years post-treatment and described (1) characteristics of interventions for breast cancer survivors as well as (2) effect size estimates for these studies. A systematic search was conducted following PRISMA guidelines with Medline, PubMed, PsycINFO, CINAHL, and Scopus databases. Data were abstracted for primary intervention strategies and other details (e.g., setting, duration, theory use). A subgroup analysis was conducted to assess intensity of exercise supervision/monitoring and intervention effectiveness. The search produced 14 unique behavior intervention trials from the US and abroad published 2005-2013. The mean sample size was 153 participants per study. All interventions included moderate-intensity activities plus various behavioral change strategies. Most interventions were partially or entirely home based. The overall standardized mean difference was 0.47 (0.23, 0.67) with p < 0.001. Most interventions were effective in producing short-term behavior changes in physical activity, but varied greatly relative to intervention strategies and intensity of supervision/monitoring. Highly structured interventions tended to produce larger behavior change effects overall, but many larger effect sizes came from interventions supported by phone counseling or e-mail. We observed that 'more' may not be better in terms of direct supervision/monitoring in physical activity behavior interventions. This may be important in exploring less resource-intensive options for effective behavior change strategies for recent post-treatment survivors.

Breast cancer mortality disparities continue, particularly for uninsured and minority women. A number of effective evidence-based interventions (EBIs) exist for addressing barriers to mammography screening; however, their uptake and use in community has been limited. Few cancer-specific studies have evaluated adapted EBIs in new contexts, and fewer still have considered implementation. This study sought to (1) evaluate the effectiveness of an adapted mammography EBI in improving appointment keeping in African American women and (2) describe processes of implementation in a new practice setting. We used the type 1 hybrid design to test effectiveness and implementation using a quasi-experimental design. Logistic regression and intent-to-treat analysis were used to evaluate mammography appointment attendance. The no-show rate was 44% (comparison) versus 19% (intervention). The adjusted odds of a woman in the intervention group attending her appointment were 3.88 (p < 0.001). The adjusted odds of a woman attending her appointment in the intent-to-treat analysis were 2.31 (p < 0.05). Adapted EBI effectiveness was 3.88 (adjusted OR) versus 2.10 (OR) for the original program, indicating enhanced program effect. A number of implementation barriers and facilitators were identified. Our findings support previous studies noting that sequentially measuring EBI efficacy and effectiveness, followed by implementation, may be missing important contextual information.

This paper describes and demonstrates the use of the systematic planning process, Intervention Mapping, to adapt an evidence-based public health intervention (EBI). We used a simplified version of Intervention Mapping (IM Adapt) to increase an intervention's fit with a new setting and population. IM Adapt guides researchers and practitioners in selecting an EBI, making decisions about whether and what to adapt, and executing the adaptation while guarding the EBI's essential elements (those responsible for effectiveness). We present a case study of a project in which we used IM Adapt to find, adapt, implement, and evaluate an EBI to improve mammography adherence for African American women in a new practice setting in Houston, Texas. IM Adapt includes the following (1) assess needs and organizational capacity; (2) find EBIs; (3) plan adaptations based on fit assessments; (4) make adaptations; (5) plan for implementation; and (6) plan for evaluation of the adapted EBI. The case study shows an example of how public health researchers and practitioners can use the tool to make it easier to find and use EBIs, thus encouraging greater uptake. IM Adapt adds to existing dissemination and adaptation models by providing detailed guidance on how to decide on effective adaptation, while maintaining the essential elements of the EBI.

When community health planners select an evidence-based intervention that has been developed and tested in one situation and adapt it for use in a different situation or community, best practice suggests needs assessment and formative research in the new setting. Cancer prevention planners who are interested in adopting and adapting evidence-based approaches need to base their choices on a sound understanding of the health or behavioral risk problem in which they mean to intervene. This requires a balancing act of weighing community information against a broader perspective from the scientific literature and using the combination to identify and adapt an evidence-based intervention program that is likely to be effective in the new setting. This report is a case study of a community and organizational assessment conducted as a foundation for selecting and recommending adaptation of an evidence-based intervention for improving mammography appointment attendance. We used an inductive sequential exploratory mixed-methods design to inform this process. The process provides a model for formative research grounding evidence-based practice for cancer control planners. Future studies that incorporate findings from needs assessment into the adaptation of the selected intervention program may promote the effective dissemination of evidence-based programs., (© 2014 Society for Public Health Education.)

Background: Adolescents with chronic disease (ACD) must develop independent disease self-management and learn to communicate effectively with their health care team to transition from pediatric to adult-oriented health care systems. Disease-specific interventions have been implemented to aid specific ACD groups through transition. A generic approach might be effective and cost-saving., Methods: Eighty-one ACD, aged 12 to 20 years, were recruited for a randomized clinical trial evaluating an 8-month transition intervention (MD2Me). MD2Me recipients received a 2-month intensive Web-based and text-delivered disease management and skill-based intervention followed by a 6-month review period. MD2Me recipients also had access to a texting algorithm for disease assessment and health care team contact. The intervention was applicable to adolescents with diverse chronic illnesses. Controls received mailed materials on general health topics. Disease management, health-related self-efficacy, and health assessments were performed at baseline and at 2 and 8 months. Frequency of patient-initiated communications was recorded over the study period. Outcomes were analyzed according to assigned treatment group over time., Results: MD2Me recipients demonstrated significant improvements in performance of disease management tasks, health-related self-efficacy, and patient-initiated communications compared with controls., Conclusions: Outcomes in ACD improved significantly among recipients of a generic, technology-based intervention. Technology can deliver transition interventions to adolescents with diverse chronic illnesses, and a generic approach offers a cost-effective means of positively influencing transition outcomes. Further research is needed to determine whether improved short-term outcomes translate into an improved transition for ACD., (Copyright © 2014 by the American Academy of Pediatrics.)

Background: In resource-constrained settings of developing countries, promotion of community-based health interventions through community health workers (CHWs) is an important strategy to improve child health. However, there are concerns about the sustainability of such programmes owing to the high rate of CHW attrition. This study examined factors influencing retention of volunteer CHWs in a cluster randomised trial on community management of under-5 fever in a rural Ghanaian district., Methods: Data were obtained from structured interviews (n=520) and focus group discussions (n=5) with CHWs. Factors influencing CHWs' decisions to remain or leave the programme were analysed using a probit model, and focus group discussion results were used to elucidate the findings., Results: The attrition rate among CHWs was 21.2%. Attrition was comparatively higher in younger age groups (25.9% in 15-25 years group, 18.2% in 26-45 years group and 16.5% in ≥46 years group). Approval of a CHW by the community (p<0.001) and the CHW's immediate family (p<0.05) were significant in influencing the probability of remaining in the programme. Motivation for retention was related to the desire to serve their communities as well as humanitarian and religious reasons., Conclusion: The relatively moderate rate of attrition could be attributed to the high level of community involvement in the selection process as well as other aspects of the intervention leading to high community approval and support. Attention for these aspects could help improve CHW retention in community-based health interventions in Ghana, and the lessons could be applied to countries within similar settings., (© The Author 2014.

Fear arousal-vividly showing people the negative health consequences of life-endangering behaviors-is popular as a method to raise awareness of risk behaviors and to change them into health-promoting behaviors. However, most data suggest that, under conditions of low efficacy, the resulting reaction will be defensive. Instead of applying fear appeals, health promoters should identify effective alternatives to fear arousal by carefully developing theory- and evidence-based programs. The Intervention Mapping (IM) protocol helps program planners to optimize chances for effectiveness. IM describes the intervention development process in six steps: (1) assessing the problem and community capacities, (2) specifying program objectives, (3) selecting theory-based intervention methods and practical applications, (4) designing and organizing the program, (5) planning, adoption, and implementation, and (6) developing an evaluation plan. Authors who used IM indicated that it helped in bringing the development of interventions to a higher level., (© 2013 The Authors.

Background: This study explored community perceptions of cultural beliefs and practices that may increase sexual risk behaviour of adolescents, to understand more about meaning they hold within the culture and how they expose adolescent orphans and non-orphans to higher risks in a high HIV and teenage pregnancy prevalence context., Methods: Using a qualitative descriptive cross-sectional design 14 focus group discussions were conducted with 78 adolescents and 68 parents/guardians purposively selected to represent their communities. Thirteen key informant interviews were also conducted with community leaders, health care and child welfare workers, and adolescents who were also selected purposively. The two methods were used to explore how cultural beliefs and practices predispose adolescent orphans and non- orphans to risky sexual behaviours. Data were analysed through line-by-line coding, grouped into families and retrieved as themes and sub-themes., Results: Identified cultural practices that predisposed adolescents orphans and non-orphans to risky sexual behaviours included: adolescent sleeping arrangements, funeral ceremonies, replacing a deceased married daughter with her younger sister in marriage, widow inheritance among boys, early marriage among girls, and preference for boys/sons. Cultural risks perceived to equally affect both orphans and non-orphans were sleeping arrangements, funeral ceremonies, and sister replacement. Factors associated more with orphans than non-orphans were widow inheritance among boys and a preference for boy over girl children., Conclusions: Adolescent sexual risk reduction programs should be developed considering the specific cultural context, using strategies that empower communities to challenge the widely accepted cultural norms that may predispose young people in general to sexual risks while targeting those that unequally influence orphans.

Background: Few studies have examined the psychometric properties and invariance of scales measuring constructs relevant to colorectal cancer screening (CRCS). We sought to: (i) evaluate the factorial validity of four core constructs associated with CRCS (benefits, barriers, self-efficacy, and optimism); and (ii) examine measurement invariance by screening status (currently screened, overdue, never screened)., Methods: We used baseline survey data from a longitudinal behavioral intervention trial to increase CRCS among U.S. veterans. Respondents were classified as currently screened (n = 3,498), overdue (n = 418), and never screened (n = 1,277). The measurement model was developed using a random half of the sample and then validated with the second half of the sample and the full baseline sample (n = 5,193). Single- and multi-group confirmatory factor analysis was used to examine measurement invariance by screening status., Results: The four-factor measurement model demonstrated good fit. Factor loadings, item intercepts, and residual item variance and covariance were invariant when comparing participants never screened and overdue for CRCS, indicating strict measurement invariance. All factor loadings were invariant among the currently screened and overdue groups. Only the benefits scale was invariant across current screeners and never screeners. Non-invariant items were primarily from the barriers scale., Conclusion: Our findings provide additional support for the construct validity of scales of CRCS benefits, barriers, self-efficacy, and optimism. A greater understanding of the differences between current and never screeners may improve measurement invariance., Impact: Measures of benefits, barriers, self-efficacy, and optimism may be used to specify intervention targets and effectively assess change pre- and post-intervention across screening groups., (©2013 AACR.)

Introduction: Despite the value of genetic counseling (GC) and genetic testing (GT) for high-risk breast cancer survivors, little is known about their uptake and validity of self-report data. This study evaluated the accuracy of self-reported genetic counseling and testing rates among breast cancer survivors., Methods: The current analysis focused on Stage 0-III female breast cancer survivors who were identified from an academic medical center's cancer registry and responded to a mailed survey (N = 452). Self-reported rates of GC and GT were validated using information from the electronic medical record., Results: Overall, 30.8 % of survivors reported having seen a genetic counselor in the time period after their breast cancer diagnosis and 33.6 % noted having a genetic test. Concordance and specificity were good for both genetic questions; concordance agreements ranged from 86-88 %, while specificity was 83-86 %. Sensitivity (97-98 %) and negative predictive values (99 %) were excellent, while the positive predictive values for both GC and GT were poor (59-63 %)., Conclusions: Among breast cancer survivors, self-reports of GC and GT were generally accurate, although a subset of respondents overestimated genetic service utilization. Future work should focus on validating GC and GT self-reports in medically underserved populations., Implications for Cancer Survivors: Genetic counseling and testing are valuable aspects of survivorship care for high-risk breast cancer survivors; accurate understanding of their use is important for survivors, clinicians, and researchers.

Purpose: Scientific communication, both written and oral, is the cornerstone of success in biomedical research, yet formal instruction is rarely provided. Trainees with little exposure to standard academic English may find developing scientific communication skills challenging. In this exploratory, hypothesis-generating qualitative study, the authors examined the process by which mentored junior researchers learn scientific communication skills, their feelings about the challenges, and their mentor's role in the process., Method: In 2010, the authors conducted semistructured focus groups and interviews to explore research trainees' and faculty mentors' perceptions and practices regarding scientific communication skills development, as part of the development phase of a larger quantitative study. The facilitator took detailed notes and verified their accuracy with participants during the sessions; a second member of the research team observed and verified the recorded notes. Three coders performed a thematic analysis, and the other authors reviewed it., Results: Forty-three trainees and 50 mentors participated. Trainees and mentors had diverging views on the role of mentoring in fostering communication skills development. Trainees expressed varying levels of self-confidence but considerable angst. Mentors felt that most trainees have low self-confidence. Trainees expressed interest in learning scientific communication skills, but mentors reported that some trainees were insufficiently motivated and seemed resistant to guidance. Both groups agreed that trainees found mentors' feedback difficult to accept., Conclusions: The degree of distress, dissatisfaction, and lack of mutual understanding between mentors and trainees was striking. These themes have important implications for best practices and resource development.

Purpose: Regular surveillance decreases the risk of recurrent cancer in colorectal cancer (CRC) survivors. However, studies suggest that receipt of follow-up tests is not consistent with guidelines. This systematic review aimed to: (1) examine receipt of recommended post-treatment surveillance tests and procedures among CRC survivors, including adherence to established guidelines, and (2) identify correlates of CRC surveillance., Methods: Systematic searches of Medline, PubMed, PsycINFO, CINAHL Plus, and Scopus databases were conducted using terms adapted for each database's keywords and subject headings. Studies were screened for inclusion using a three-step process: (1) lead author reviewed abstracts of all eligible studies; (2) coauthors reviewed random 5 % samples of abstracts; and (3) two sets of coauthors reviewed all "maybe" abstracts. Discrepancies were adjudicated through discussion., Results: Thirty-four studies are included in the review. Overall adherence ranged from 12 to 87 %. Within the initial 12 to 18 months post-treatment, adherence to recommended office visits was 93 %. Adherence ranged from 78 to 98 % for physical exams, 18-61 % for colonoscopy, and 17-71 % for carcinoembryonic antigen (CEA) testing. By 2 to 3 years post-treatment, cumulative adherence ranged from 70 to 88 % for office visits, 89-93 % for physical exams, 49-94 % for colonoscopy, and 7-79 % for CEA testing. Between 18 and 28 % of CRC survivors received greater than recommended overall surveillance; overuse of physical exams (42 %), colonoscopy (24-76 %), and metastatic disease testing (1-29 %) was also prevalent. Studies of correlates of CRC surveillance focused on sociodemographic and disease/treatment characteristics, and patterns of association were inconsistent across studies., Conclusions: Deviation from surveillance recommendations includes both under- and overuse. Examination of modifiable determinants is needed to inform interventions targeting appropriate and timely receipt of recommended surveillance., Implications for Cancer Survivors: Among CRC survivors, it remains unclear what modifiable psychosocial factors are associated with the observed under- and overuse of surveillance. Understanding and intervening with these psychosocial factors is critical to improving adherence to guideline-recommended surveillance and thereby reducing mortality among this group of survivors.

Background: Some studies show orphanhood to be associated with increased sexual risk-taking while others have not established this relationship, but have found factors other than orphanhood as predictors of sexual risk behaviours and outcomes among adolescents. This study examines community members' perceptions of how poverty influences adolescent sexual behaviour and outcomes in four districts of Nyanza Province, Kenya., Methods: Eight study sites within the four districts were randomly selected. Focus group discussions were conducted with a purposive sample of adolescents, parents and caregivers. Key informant interviews were undertaken with a purposive sample of community leaders, child welfare and healthcare workers, and adolescents. The two methods elicited information on factors perceived to predispose adolescent orphans and non-orphans to sexual risks. Data were analysed through line-by-line coding, grouped into families and retrieved as themes and sub-themes., Results: Participants included 147 adolescents and parents/caregivers in 14 focus groups and 13 key informants. Poverty emerged as a key predisposing factor to sexual risk behaviour among orphans and non-orphans. Poverty was associated with lack of food, poor housing, school dropout, and engaging in income generating activities, all of which increase their vulnerability to transactional sex, early marriage, sexual experimentation, and the eventual consequences of increased risk of unintended pregnancies and STI/HIV., Conclusion: Poverty was perceived to contribute to increasing sexual risks among orphan and non-orphan adolescents through survival strategies adopted to be able to meet their basic needs. Policies for prevention and intervention that target adolescents in a generalized poverty and HIV epidemic should integrate economic empowerment for caregivers and life skills for adolescents to reduce vulnerabilities of orphan and non-orphan adolescents to sexual risk behaviour.

Background: Guideline adherence in physical therapy is far from optimal, which has consequences for the effectiveness and efficiency of physical therapy care. Programmes to enhance guideline adherence have, so far, been relatively ineffective. We systematically developed a theory-based Quality Improvement in Physical Therapy (QUIP) programme aimed at the individual performance level (practicing physiotherapists; PTs) and the practice organization level (practice quality manager; PQM). The aim of the study was to pilot test the multilevel QUIP programme's effectiveness and the fidelity, acceptability and feasibility of its implementation., Methods: A one-group, pre-test, post-test pilot study (N = 8 practices; N = 32 PTs, 8 of whom were also PQMs) done between September and December 2009. Guideline adherence was measured using clinical vignettes that addressed 12 quality indicators reflecting the guidelines' main recommendations. Determinants of adherence were measured using quantitative methods (questionnaires). Delivery of the programme and management changes were assessed using qualitative methods (observations, group interviews, and document analyses). Changes in adherence and determinants were tested in the paired samples T-tests and expressed in effect sizes (Cohen's d)., Results: Overall adherence did not change (3.1%; p = .138). Adherence to three quality indicators improved (8%, 24%, 43%; .000 ≤ p ≤ .023). Adherence to one quality indicator decreased (-15.7%; p = .004). Scores on various determinants of individual performance improved and favourable changes at practice organizational level were observed. Improvements were associated with the programme's multilevel approach, collective goal setting, and the application of self-regulation; unfavourable findings with programme deficits. The one-group pre-test post-test design limits the internal validity of the study, the self-selected sample its external validity., Conclusions: The QUIP programme has the potential to change physical therapy practice but needs considerable revision to induce the ongoing quality improvement process that is required to optimize overall guideline adherence. To assess its value, the programme needs to be tested in a randomized controlled trial.

Objective: The purpose of this study is to describe the post-treatment goals of colorectal cancer (CRC) survivors. We sought to determine whether goals were a salient concept during the period immediately following treatment, and whether a goal-setting intervention might be feasible and acceptable to these patients., Method: Semi-structured qualitative interviews were administered to a convenience sample of 41 CRC patients who were 0-24 months post-treatment. Topics discussed included expectations and goals for future health, cancer prevention awareness, health-promoting behavior-change goals, and post-treatment cancer issues. Content analysis was used to explore emergent themes., Results: Overall, participants' health-related goals were: being healthy, getting back to normal, and not having a cancer recurrence. Most of the CRC survivors reported being proactive with their health by maintaining healthy behaviors or making healthy behavior changes, or had goals to change their behavior. All respondents had plans to maintain follow-up care and regular screening appointments. Some patients were managing treatment side effects or non-cancer issues that limited their functional abilities. Many respondents were satisfied with the care they received, and felt it was now their responsibility to do their part in taking care of themselves., Significance of Results: CRC survivors talk about goals, and many of them are either making or have an interest in making health behavior changes. Self-management support could be an appropriate strategy to assist patients with achieving their health goals post-treatment. Patients may need help addressing lingering treatment side effects or non-cancer issues. Healthcare providers should consider assessing patients' goals to help patients resolve post-treatment issues and promote healthy behaviors.

Purpose: Little is known about cancer survivors' receptivity to being contacted through cancer registries for research and health promotion efforts. We sought to (1) determine breast and colorectal cancer (CRC) survivors' responsiveness to a mailed survey using an academic medical center's cancer registry, (2) assess whether responsiveness varied according to sociodemographic characteristics and medical history, and (3) examine the prevalence and correlates of respondents' awareness and willingness to be contacted through the state cancer registry for future research studies., Methods: Stage 0-III breast and CRC survivors diagnosed between January 2004 and December 2009 were identified from an academic medical center cancer registry. Survivors were mailed an invitation letter with an opt-out option, along with a survey assessing sociodemographic characteristics, medical history, and follow-up cancer care access and utilization., Results: A total of 452 (31.4 %) breast and 53 (22.2 %) CRC survivors responded. Willingness to be contacted through the state cancer registry was high among both breast (74 %) and CRC (64 %) respondents even though few were aware of the registry and even fewer knew that their information was in the registry. In multivariable analyses, tumor stage I and not having a family history of cancer were associated with willingness among breast and CRC survivors, respectively., Conclusions: Our findings support the use of state cancer registries to contact survivors for participation in research studies., Implications for Cancer Survivors: Survivors would benefit from partnerships between researchers and cancer registries that are focused on health promotion interventions.

A household survey of male and female adolescents was conducted to establish whether orphanhood or other factors contribute to risky sexual behavior. Results show that orphanhood was not associated with risky sexual behavior. Sleeping in a different house from the household head and attending social activities at night were positively associated with sexual activity and transactional sex among boys and girls. Older adolescents were more likely to be sexually active while urban residents, and those who perceived their caregivers as able to provide for their basic needs, were less likely to have ever engaged in sex. Condom use at last sex was associated with older age and having talked with parents/caregivers about sexual risks. Interventions should address these predictors, promote risk reduction among all adolescents irrespective of orphan status, and strengthen parents'/guardians' capacity to discuss sexuality with adolescents and to provide for their basic needs.

Adjuvant hormonal therapy significantly improves long-term survival of breast cancer patients with hormone receptor-positive disease. Despite the proven clinical efficacy of tamoxifen and aromatase inhibitors, many breast cancer survivors either fail to take the correct dosage at the prescribed frequency (adherence) or discontinue therapy (persistence). This systematic review aims to: (1) determine the prevalence of adherence and persistence to adjuvant hormonal therapy among breast cancer survivors in clinical practice, and (2) identify correlates of adherence and persistence. We searched Medline, PubMed, PsycINFO, and CINAHL for studies that measured rates and/or correlates of adherence and/or persistence to adjuvant hormonal therapy. Studies were reviewed in a multi-step process: (1) the lead author screened titles and abstracts of all potentially eligible studies; (2) each coauthor reviewed a random 5 % sample of abstracts; and (3) two sets of coauthors each reviewed half of all "maybe" abstracts. Any disagreements were discussed until consensus was reached. Twenty-nine studies met inclusion criteria. Prevalence of adherence ranged from 41 to 72 % and discontinuation (i.e., nonpersistence) ranged from 31 to 73 %, measured at the end of 5 years of treatment. Extremes of age (older or younger), increasing out-of-pocket costs, follow-up care with a general practitioner (vs. oncologist), higher CYP2D6 activity, switching from one form of therapy to another, and treatment side effects were negatively associated with adherence and/or persistence. Taking more medications at baseline, referral to an oncologist, and earlier year at diagnosis were positively associated with adherence and/or persistence. Adherence and persistence to adjuvant hormonal therapy among breast cancer survivors is suboptimal. Many of the correlates of adherence and persistence studied to date are not modifiable. Our review reveals a critical need for further research on modifiable factors associated with adherence to adjuvant hormonal therapy, and the development of behavioral interventions to improve adherence in this population.

Computer-based multimedia technologies can be used to tailor health messages, but promotoras (Spanish-speaking community health workers) rarely use these tools. Promotoras delivered health messages about colorectal cancer screening to medically underserved Latinos in South Texas using two small media formats: a "low-tech" format (flipchart and video) and a "high-tech" format consisting of a tailored, interactive computer program delivered on a tablet computer. Using qualitative methods, the authors observed promotora training and intervention delivery and conducted interviews with five promotoras to compare and contrast program implementation of both formats. The authors discuss the ways each format aided or challenged promotoras' intervention delivery. Findings reveal that some aspects of both formats enhanced intervention delivery by tapping into Latino health communication preferences and facilitating interpersonal communication, whereas other aspects hindered intervention delivery. This study contributes to our understanding of how community health workers use low- and high-tech small media formats when delivering health messages to Latinos.

Background: The purpose of this study was to identify factors associated with colorectal cancer (CRC) screening test preference and examine the association between test preference and test completed., Methods: Patients (n = 1224) were 50-70 years, at average CRC risk, and overdue for screening. Outcome variables were preference for fecal occult blood test (FOBT), colonoscopy (COL), sigmoidoscopy (SIG), or barium enema (BE), measured by telephone survey, and concordance between test preference and test completed assessed using medical records., Results: Thirty-five percent preferred FOBT, 41.1% COL, 12.7% SIG, and 5.7% BE. Preference for SIG or COL was associated with having a physician recommendation, greater screening readiness, test-specific self-efficacy, greater CRC worry, and perceived pros of screening. Preference for FOBT was associated with self-efficacy for doing FOBT. Participants who preferred COL were more likely to complete COL compared with those who preferred another test. Of those screened, only 50% received their preferred test. Those not receiving their preferred test most often received COL (52%)., Conclusions: Lack of concordance between patient preference and test completed suggests that patients' preferences are not well incorporated into screening discussions and test decisions, which could contribute to low screening uptake. Physicians should acknowledge patients' preferences when discussing test options and making recommendations, which may increase patients' receptivity to screening., (Copyright © 2011 American Cancer Society.)

Background. Despite the availability of multiple effective tests for colorectal cancer (CRC), screening rates are low. Greater understanding of barriers between screeners and nonscreeners may improve public health initiatives to increase CRC screening (CRCS). Methods. We conducted a content analysis of 625 responses to the question: "Was there anything that would have made getting tested easier?" Respondents were patients at a multispecialty practice who participated in a behavioral intervention trial to increase CRCS. Using clinic records, we classified patients as early-screeners (<6 months), late-screeners(6-12 months), and nonscreeners (>12 months). Results. Both screeners and nonscreeners reported the same categories of barriers. However, early-screeners predominantly cited dislike of test attributes such as bowel preparation, whereas nonscreeners cited concerns regarding finances and work and family responsibilities. Conclusion. Multilevel strategies that address scheduling barriers and external screening barriers may improve CRCS. Future studies may test hypotheses about mediators explaining how screeners overcome barriers.

Objective: The prevailing wisdom in the field of health-related behavior change is that well-designed and effective interventions are guided by theory., Methods: Using the framework of intervention mapping, we describe and provide examples of how investigators can effectively select and use theory to design, test, and report interventions., Results: We propose five roles for theory and evidence about theories: a) identification of behavior and determinants of behavior related to a specified health problem (i.e., the logic model of the problem); b) explication of a causal model that includes theoretical constructs for producing change in the behavior of interest (i.e., the logic model of change); c) selection of intervention methods and delivery of practical applications to achieve changes in health behavior; d) evaluation of the resulting intervention including theoretical mediating variables; and e) reporting of the active ingredients of the intervention together with the evaluation results., Conclusions: In problem-driven applied behavioral or social science, researchers use one or multiple theories, empiric evidence, and new research, both to assess a problem and to solve or prevent a problem. Furthermore, the theories for description of the problem may differ from the theories for its solution. In an applied approach, the main focus is on solving problems regarding health behavior change and improvement of health outcomes, and the criteria for success are formulated in terms of the problem rather than the theory. Resulting contributions to theory development may be quite useful, but they are peripheral to the problem-solving process.

Background: Although diabetes mellitus is of high concern in Iran, and the level of control is unacceptable, few qualitative studies have been carried out to reflect the experiences of patients on the barriers and motivators to self-care. This study aimed to explore a culturally based experience of Iranian diabetic patients regarding the personal and environmental barriers to and facilitating factors for diabetes self-care., Methods: Six focus groups were conducted among type 2 diabetic patients in the Charity Foundation for Special Diseases' diabetes clinic. Purposeful sampling was used. Newly diagnosed patients (less than six months) and all type 1 diabetic patients were excluded. Three focus groups were held on for each sex. A total of 43 patients participated in the study. Frame-work analysis was used to extract the themes from the data., Results: DATA ANALYSIS SHOWED FIVE MAIN BARRIERS: physical barriers (such as physical effects of diabetes); psychological barriers (such as health beliefs); educational barriers (such as lack of knowledge about diabetes); social barriers (such as group pressure); and care system barriers (such as service availability). Along with the barriers, there were some motivators that the participants mentioned as a stimuli to control their diabetes. They include beliefs about diabetes, perceived responsibility for family, religious beliefs, and the views of significant others., Conclusion: Culturally based interventions are needed to improve diabetes care management in Iran. In addition to personal factors, diabetes health educators should pay attention to the environmental factors when they develop programs.

Objective: We assessed the short-term effects of a community-based intervention for Hispanic men to encourage informed decision making (IDM) about prostate cancer screening with prostate specific antigen (PSA)., Methods: All senior social and housing centers in El Paso, TX were randomized to intervention, a group-based Spanish language educational program facilitated by promotores (12 centers; 161 men) [I's], or to control, promotores-facilitated diabetes video and discussion (13 centers; 160 men) [C's]., Results: Participants had low levels of schooling and baseline knowledge; 44% reported previous PSA testing. At post-test, the I's made large knowledge gains, increased their understanding that experts disagree about testing, shifted toward more active decision making roles, were more likely to believe that it is important to weigh the advantages and disadvantages of screening and to anticipate potential screening outcomes in making a decision, and were less likely to consider the screening decision easy. The I's did not change in their screening intention or the belief that choosing not to be screened could be a responsible choice., Conclusions: A community-based intervention to support IDM for prostate cancer screening can increase knowledge and may promote more active involvement in decision making about prostate cancer screening. Such an approach can increase knowledge and may promote more active involvement in decision making about prostate cancer screening., Practice Implications: It is feasible to develop and implement a community-based intervention program to promote IDM for prostate cancer screening., (Copyright © 2010 Elsevier Ireland Ltd.

Evidence-based health promotion programmes, including HIV/AIDS prevention and sexuality education programmes, are often transferred to other cultures, priority groups and implementation settings. Challenges in this process include the identification of retaining core elements that relate to the programme's effectiveness while making changes that enhances acceptance in the new context and for the new priority group. This paper describes the use of a systematic approach to programme adaptation using a case study as an example. Intervention Mapping, a protocol for the development of evidence-based behaviour change interventions, was used to adapt the comprehensive school-based sexuality education programme 'The World Starts With Me'. The programme was developed for a priority population in Uganda and adapted to a programme for Indonesian secondary school students. The approach helped to systematically address the complexity and challenges of programme adaptation and to find a balance between preservation of essential programme elements (i.e. logic models) that may be crucial to the programme's effectiveness, including key objectives and theoretical behaviour change methods, and the adaptation of the programme to be acceptable to the new priority group and the programme implementers.

Objectives: Screening for colorectal cancer is considered cost effective, but is underutilized in the U.S. Information on the efficiency of "tailored interventions" to promote colorectal cancer screening in primary care settings is limited. The paper reports the results of a cost effectiveness analysis that compared a survey-only control group to a Centers for Disease Control (CDC) web-based intervention (screen for life) and to a tailored interactive computer-based intervention., Methods: A randomized controlled trial of people 50 and over, was conducted to test the interventions. The sample was 1224 participants 50-70 years of age, recruited from Kelsey-Seybold Clinic, a large multi-specialty clinic in Houston, Texas. Screening status was obtained by medical chart review after a 12-month follow-up period. An "intention to treat" analysis and micro costing from the patient and provider perspectives were used to estimate the costs and effects. Analysis of statistical uncertainty was conducted using nonparametric bootstrapping., Results: The estimated cost of implementing the web-based intervention was $40 per person and the cost of the tailored intervention was $45 per person. The additional cost per person screened for the web-based intervention compared to no intervention was $2602 and the tailored intervention was no more effective than the web-based strategy., Conclusions: The tailored intervention was less cost-effective than the web-based intervention for colorectal cancer screening promotion. The web-based intervention was less cost-effective than previous studies of in-reach colorectal cancer screening promotion. Researchers need to continue developing and evaluating the effectiveness and cost-effectiveness of interventions to increase colorectal cancer screening.

Background: Strategies are needed to improve the translation of clinical trial results into practice. We assessed the impact of the ALLHAT/JNC7 Dissemination Project's academic detailing component on thiazide-type diuretic prescribing (ALLHAT indicates Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial; JNC7 indicates the Seventh Report of the Joint National Committee on Detection, Evaluation, and Treatment of High Blood Pressure)., Methods: We used 2 national databases available from IMS Health: a physician survey of medications reported for hypertension and a pharmacy dispensing database on antihypertensive medications. At a county level, we correlated medication data with Dissemination Project intensity. Practices before the Dissemination Project in 2004 were compared with those after its completion in 2007. We also examined 2000-2008 national trends., Results: Academic detailing reached 18 524 physicians in 1698 venues via 147 investigator-educators. We noted an association between ALLHAT/JNC7 academic detailing activities and increased prescribing of thiazide-type diuretics. Physician survey data showed that the percentage of hypertension visits where the physician recorded a thiazide-type diuretic increased the most in counties where academic detailing activity was the highest (an increase of 8.6%, from 37.9% to 46.5%) compared with counties where activity was moderate (an increase of 2%) or low (a decrease of 2%), or where there was none (an increase of 2%; P value for trend, <.05). Pharmacy dispensing data showed that thiazide-type diuretic prescribing increased by 8.7% in counties with Dissemination Project activities compared with 3.9% in those without activities (P < .001). Nationally, thiazide-type diuretic use did not increase between 2004 and 2008., Conclusions: The ALLHAT/JNC7 Dissemination Project was associated with a small effect on thiazide-type diuretic use consistent with its small dose and the potential of external factors to diminish its impact. Academic detailing may increase physicians' implementation of clinical trial results, thereby making prescribing more consistent with evidence.

Implementation of HIV care and treatment programs in sub-Saharan Africa is a complex undertaking that requires training of health care providers (HCPs). Many sub-Saharan African countries have introduced training programs to build human resources for health. Evaluation of the ongoing trainings is warranted so that programs can be improved. The purpose of this study was to evaluate Baylor International Pediatric AIDS Initiative's (BIPAI) HCP training program in Swaziland. The specific aims were: (1) to assess coverage and delivery of the training program; and (2) to determine the impact of the training program on HCPs' knowledge about HIV and pediatric practices, attitudes toward HIV/AIDS patients, and self-efficacy to provide antiretroviral therapy (ART). The evaluation was a multimethod design with two types of data collection and analysis: (1) one-group pretest-posttest survey with 101 HCPs; and (2) semi-structured in-depth interviews with seven trainers from Baylor College of Medicine and 16 local HCPs in Swaziland. Quantitative data were analyzed using Stata Statistical Software version 8.2 for descriptive and multivariate analysis while factor analysis was done using Statistical Program for Social Sciences version 14. The transcribed interviews were analyzed using a didactic approach. Process evaluation showed that the training had good coverage, was delivered as intended, and improved as the work progressed. The training program led to a significant increase (p=0.0000) in HCPs' knowledge about HIV/AIDS, ART, and relevant clinical pediatrics practices between pretest (mean 68.7% SD 13.7) and post training (mean 84.0% SD 12.0). The training program also increased trainees' self-efficacy to provide ART and their attitudes toward AIDS patients (p=0.0000 and 0.02, respectively). In conclusion, BIPAI training program in Swaziland had good coverage of all health care facilities and HCPs in Swaziland. The training was effective in imparting knowledge and skills to HCPs and in their attitudes toward HIV/AIDS patients.

Background: Despite the availability of multiple effective screening tests for colorectal cancer, screening rates remain suboptimal. The literature documents patient preferences for different test types and recommends a shared decision-making approach for physician-patient colorectal cancer screening (CRCS) discussions, but it is unknown whether such communication about CRCS preferences and options actually occurs in busy primary-care settings., Objective: Describe physician-patient CRCS discussions during a wellness visit., Design: Cross-sectional; patients audio-recorded with physicians., Participants: A subset of patients (N = 64) participating in a behavioral intervention trial designed to increase CRCS who completed a wellness visit during the trial with a participating physician (N = 8)., Approach: Transcripts were analyzed using qualitative methods., Results: Physicians in this sample consistently recommended CRCS, but focused on colonoscopy. Physicians did not offer a fecal occult blood test alone as a screening choice, which may have created missed opportunities for some patients to get screened. In this single visit, physicians' communication processes generally precluded discussion of patients' test preferences and did not facilitate shared decision-making. Patients' questions indicated their interest in different CRCS test types and appeared to elicit more information from physicians. Some patients remained resistant to CRCS after discussing it with a physician., Conclusion: If a preference for colonoscopy is widespread among primary-care physicians, the implications for intervention are either to prepare patients for this preference or to train physicians to offer options when recommending screening to patients.

Naturally occurring hepatitis C virus (HCV) subgenomic RNAs have been found in several HCV patients. These subgenomic deletion mutants, mostly lacking the genes encoding envelope glycoproteins, were found in both liver and serum, where their relatively high abundance suggests that they are capable of autonomous replication and can be packaged and secreted in viral particles, presumably harboring the envelope proteins from wild type virus coinfecting the same cell. We recapitulated some of these natural subgenomic deletions in the context of the isolate JFH-1 and confirmed these hypotheses in vitro. In Huh-7.5 cells, these deletion-containing genomes show robust replication and can be efficiently trans-packaged and infect naïve Huh-7.5 cells when cotransfected with the full-length wild-type J6/JFH genome. The genome structure of these natural subgenomic deletion mutants was dissected, and the maintenance of both core and NS2 regions was proven to be significant for efficient replication and trans-packaging. To further explore the requirements needed to achieve trans-complementation, we provided different combinations of structural proteins in trans. Optimal trans-complementation was obtained when fragments of the polyprotein encompassing core to p7 or E1 to NS2 were expressed. Finally, we generated a stable helper cell line, constitutively expressing the structural proteins from core to p7, which efficiently supports trans-complementation of a subgenomic deletion encompassing amino acids 284 to 732. This cell line can produce and be infected by defective particles, thus representing a powerful tool to investigate the life cycle and relevance of natural HCV subgenomic deletion mutants in vivo.

Background: Conventional dissemination of clinical trial results has inconsistent impact on physician practices. A more comprehensive plan to influence determinants of prescribing practices is warranted., Purpose: To report the response from the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial to the National Heart, Lung, and Blood Institute's requirement for dissemination and evaluation of trials with potential immediate public health applicability., Methods: ALLHAT's dissemination plan had two-components: (1) a traditional approach of media coverage, scientific presentation, and publication; and (2) a theory-based approach targeting determinants of clinician behavior. Strategies included: (1) academic detailing, in which physicians approach colleagues regarding blood pressure management, (2) direct patient messages to stimulate communication with physicians regarding blood pressure control, (3) approaches to formulary systems to use educational and economic incentives for evidence-based prescription, and (4) direct professional organization appeals to clinicians., Results: One hundred and forty-seven Investigator Educators reported 1698 presentations to 18,524 clinicians in 41 states and the District of Columbia. The pre- and post-test responses of 1709 clinicians in the face-to-face meetings indicated significant changes in expectations for positive patient outcomes and intention to prescribe diuretics. Information was mailed to 55 individuals representing 20 professional organizations and to eight formulary systems. Direct-to-patient messages were provided to 14 sites that host patient newsletters and Web sites such as health plans and insurance companies, 62 print mass media outlets, and 12 broadcast media sites., Limitations: It was not within the scope of the project to conduct a randomized trial of the impact of the dissemination. However, impact evaluation using quasi-experimental designs is ongoing., Conclusion: A large multi-method dissemination of clinical trial results is feasible. Planning for dissemination efforts, including evaluation research, should be considered as a part of the funding and design of the clinical trial and should begin early in trial planning.

Hepatitis C virus (HCV) exists in six major genotypes. Compared with the 1b enzyme, genotype 2b HCV polymerase exhibits a more than 100-fold reduction in sensitivity to the indole-N-acetamide class of non-nucleoside inhibitors. These compounds have been shown to bind in a pocket occupied by helix A of the mobile Lambda1 loop in the apoenzyme. The three-dimensional structure of the HCV polymerase from genotype 2b was determined to 1.9-A resolution and compared with the genotype 1b enzyme. This structural analysis suggests that genotypic variants result in a different shape of the inhibitor binding site. Mutants of the inhibitor binding pocket were generated in a 1b enzyme and evaluated for their binding affinity and sensitivity to inhibition by indole-N-acetamides. Most of the point mutants showed little variation in activity and IC(50), with the exception of 15- and 7-fold increases in IC(50) for Leu392Ile and Val494Ala mutants (1b-->2b), respectively. Furthermore, a 1b replicon with 20-fold resistance to this class of inhibitors was selected and shown to contain the Leu392Ile mutation. Chimeric enzymes, where the 2b fingertip Lambda1 loop, pocket or both replaced the corresponding regions of the 1b enzyme, were also generated. The fingertip chimera retained 1b-like inhibitor binding affinity, whereas the other two chimeric constructs and the 2b enzyme displayed between 50- and 100-fold reduction in binding affinity. Together, these data suggest that differences in the amino acid composition and shape of the indole-N-acetamide binding pocket are responsible for the resistance of the 2b polymerase to this class of inhibitors.

People fearful of being stigmatized by a health-related condition often do not embrace prevention behaviors or seek medical help. They may adhere poorly to treatment regimes for disease and abruptly terminate much needed treatment. Globally, 120 million--many poor women--suffer consequences of lymphatic filariasis that include stigmatizing lymphedema or elephantiasis of the leg. We investigated how women with lymphedema from two different cultures experience stigma and its consequences. Our qualitative data were collected from 56 Dominican women and 48 Ghanaian women with lymphedema. A lymphedema-related stigma framework was developed from constructs derived from the literature and emergent themes from the data. Women described a spectrum of enacted, perceived, and internalized stigma experiences, such as being criticized and isolated by the community, health providers, and even by friends and relatives; they were often denied access to education and meaningful work roles. Some antecedents, consequences, coping strategies, and outcomes of these experiences varied across cultures, with Dominican women faring somewhat better than Ghanaians. Poverty, poor access to health care resources, limited education, and diminished social support challenged the coping strategies of many women and exacerbated negative consequences of lymphedema-related stigma.

Noise-induced hearing loss (NIHL) is the second most prevalent self-reported occupational illness or injury in the U.S., and agricultural workers experience high rates of hearing loss. This article uses Intervention Mapping (IM), a systematic approach to intervention development, to make recommendations for a program to improve hearing loss protection among farmworkers and managers. Final recommendations, based on previous work in the literature on hearing loss prevention, qualitative formative research, and theoretical considerations, include a specification of a multilevel theory- and evidence-based hearing protection program for farmworkers and farm managers. Twelve performance objectives (e.g., "monitor hearing and hearing loss with regular hearing testing") are specified and crossed with six relevant determinants (knowledge and behavioral capability; perceived exposure and susceptibility and noise annoyance; outcome expectations; barriers; social influence; skills and self-efficacy) to create a highly detailed matrix of change objectives for farmworkers and for their managers. These change objectives are then grouped into five categories: two for both farmworkers and their managers (noticing exposures, taking action) and three only for the latter (surveying and planning, implementation and evaluation, and communication). Theoretical methods and practical strategies, including program materials and activities, are then delineated.

Background & Aims: Gastroenterologists commonly perceive themselves to be at increased legal risk because they perform invasive procedures. However, there is little published information about gastroenterology (GI) malpractice claims. The goal of this study was to evaluate available malpractice claim data within GI., Methods: This study was a database analysis of GI claims submitted by insurance companies to the Physician Insurers Association of America Data Sharing Project from January 1, 1985, to December 31, 2005. Another analysis from 2005 compared GI claims with other subspecialties., Results: Sixty-six percent of physicians involved in claims had previous claims experience. The most common reasons for claims were errors in diagnosis (28%) and improper performance of a procedure (25%). Seventy-two percent of reported closed claims were settled out of court. Of 12,367 total claims in 2005, only 233 (1.8%) were within GI. GI ranked below other procedurally based subspecialties in numbers of claims per physician., Conclusions: GI does not rank highly among subspecialties in malpractice claims and only a minority of claims are procedure-related. Physicians with claims experience are likely to have further claims against them and should consider evaluating their practices.

The psychological states of Dominican women with chronic lymphedema and elephantiasis of the leg and the coping strategies they used to ameliorate the negative psychological effects of this condition were explored using modified precepts of grounded theory method. Qualitative data were gathered through in-depth interviewing and focus group discussions held in the Dominican Republic. Thematic results found that compounding their physical disfigurement, functional limitations, and social losses were feelings of depression, embarrassment, social isolation, and despair. Adaptive problem solving and emotion-focused coping strategies that emerged during analysis also are discussed. It is recommended that management of psychological distress should be a significant component of lymphedema management programs in developing countries.

Objective: Goal-setting is an approach to collaborative chronic care that involves clinicians and patients working together to set goals and to initiate and maintain specific self-care behaviors. Using patients' own perspectives, this study describes how goals for the self-management of hypertension are developed and whether or not they conform to the characteristics of effective goal-setting., Methods: Qualitative methodology was used to explore the process of setting self-management goals for hypertensive patients. Thirty patients participated in semi-structured interviews that ascertained the detail and specificity of self-care goals, timing and quality of feedback for setting and monitoring goals and the role of family members and caregivers in setting goals., Results: Patients understood the risks associated with hypertension, had intentions to control their disease, reported conducting at least one self-care task and set informal goals for themselves; however, these goals lacked the characteristics needed to initiate and maintain behavior change., Conclusion: Patient goal-setting is underdeveloped and poorly supported in chronic hypertension care. Future studies need to examine ways to support effective goal-setting., Practice Implications: As part of chronic hypertension care, health care providers should incorporate time and support for dedicated goal-setting to improve the effectiveness of self-management behaviors.
