Aim To review randomized controlled trials to assess efficacy of a prize-based contingency management procedure in reducing substance use (where a drug-free breath or urine sample provides a chance of winning a prize). Methods A meta-analysis was conducted on papers published from January 2000 to February 2013 to determine the effect size of studies comparing prize-based contingency management to a treatment-as-usual control condition (k = 19 studies). Parallel analyses evaluated the efficacy of both short- (k = nine studies) and long-term outcomes (k = six studies) of prize-based contingency management. Results The average end-of-treatment effect size (Cohen’s d) was 0.46 [95% confidence interval (CI) = 0.37, 0.54]. This effect size decreased at the short-term (≤3-month) post-intervention follow-up to 0.33 (95% CI = 0.12, 0.54) and at the 6-month follow-up time-point there was no detectable effect [d = −0.09 (95% CI = −0.28, 0.10)]. Conclusion Adding prize-based contingency management to behavioral support for substance use disorders can increase short-term abstinence, but the effect does not appear to persist to 6 months.

We evaluate the immediate impact of a nutrition and gender behaviour change communication on dietary quality in rural communities in Myanmar and assess whether the communication helped mitigate the effect of the COVID‐19 crisis on dietary quality. The intervention was designed and implemented as a cluster‐randomised controlled trial in which 15 villages received the intervention and 15 control villages did not. The intervention was implemented from June to October 2020. This paper provides an assessment of the intervention's impact on dietary quality based on the results of two phone surveys conducted in August and October 2020. Immediate impacts of the intervention indicate an improvement in women's dietary diversity scores by half a food group out of 10. At baseline, 44% of women were likely to have consumed inadequately diverse diets; results indicate that 6% (p‐value: 0.003, SE: 0.02) fewer sample women were likely to have consumed inadequately diverse diets. More women in treatment villages consumed pulses, nuts, eggs and Vitamin A‐rich foods daily than in control villages. In response to economic shocks related to COVID‐19, households in the treatment villages were less likely to reduce the quantity of meat and fish consumption than in control villages. The long‐term impacts of the intervention need to be continuously evaluated. [ABSTRACT FROM AUTHOR]

Background Over the past 60 years, the view that 'alcoholism' is a disease for which the only acceptable goal of treatment is abstinence has given way to the recognition that alcohol use disorders ( AUDs) occur on a continuum of severity, for which a variety of treatment options are appropriate. However, because the available treatments for AUDs are not effective for everyone, more research is needed to develop novel and more efficacious treatments to address the range of AUD severity in diverse populations. Here we offer recommendations for the design and analysis of alcohol treatment trials, with a specific focus on the careful conduct of randomized clinical trials of medications and nonpharmacological interventions for AUDs. Methods This paper provides a narrative review of the quality of published clinical trials and recommendations for the optimal design and analysis of treatment trials for AUDs. Results Despite considerable improvements in the design of alcohol clinical trials over the past 2 decades, many studies of AUD treatments have used faulty design features and statistical methods that are known to produce biased estimates of treatment efficacy. Conclusions The published statistical and methodological literatures provide clear guidance on methods to improve clinical trial design and analysis. Consistent use of state-of-the-art design features and analytic approaches will enhance the internal and external validity of treatment trials for AUDs across the spectrum of severity. The ultimate result of this attention to methodological rigor is that better treatment options will be identified for patients with an AUD. [ABSTRACT FROM AUTHOR]

Objective: Certain treatments have demonstrated acute efficacy for binge‐eating disorder (BED) but many patients who receive "evidence‐based" interventions do not derive sufficient benefit. Given the dearth of controlled research examining treatments for patients who fail to respond to initial interventions, this study tested the efficacy of cognitive‐behavioral therapy (CBT) for patients with BED who do not respond to initial acute treatments. Methods: Prospective randomized double‐blind placebo‐controlled single‐site trial, conducted August 2017–December 2021, tested 16‐weeks of therapist‐led CBT for non‐responders to initial treatment (naltrexone/bupropion and/or behavioral therapy) for BED with obesity. Thirty‐one patients (mean age 46.3 years, 77.4% women, 80.6% White, mean BMI 38.99 kg/m2) who were non‐responders to initial acute treatments were randomized to CBT (N = 18) or no‐CBT (N = 13), in addition to continuing double‐blinded pharmacotherapy. Independent assessments were performed at baseline, throughout treatment, and posttreatment; 83.9% completed posttreatment assessments. Results: Intention‐to‐treat remission rates were significantly higher for CBT (61.1%; N = 11/18) than no‐CBT (7.7%; N = 1/13). Mixed models of binge‐eating frequency (assessed using complementary methods) converged revealing a significant interaction between CBT and time and a significant main effect of CBT. Binge‐eating frequency decreased significantly with CBT but did not change significantly with no‐CBT. Since only four patients received behavioral treatment during the acute treatments, we performed "sensitivity‐type" analyses restricted to the 27 patients who received pharmacotherapy during the acute treatment and found the same pattern of findings for CBT versus no‐CBT. Conclusions: Adult patients with BED who fail to respond to initial pharmacological treatments should be offered CBT. Public Significance: Even with leading evidence‐based treatments for binge‐eating disorder, many patients do not derive sufficient benefit. Almost no controlled research has examined treatments for patients who fail to respond to initial interventions. This study found that that cognitive‐behavioral therapy was effective for patients with binge‐eating disorder who did not respond to initial interventions, with 61% achieving abstinence.

Background: Cognitive bias theories propose that reducing threat hypervigilance in mental disorders can augment cognitive behavioral therapy (CBT) outcomes. However, no studies have tested whether adding attention bias modification (ABM) can effectively enhance CBT's effects on anxiety sensitivity (AS), electromyography (EMG), and skin conductance (SC) for panic disorder (PD). This pilot randomized controlled trial (RCT) thus aimed to evaluate the efficacy of CBT + ABM (vs. CBT plus attention training placebo; PBO) on those outcomes. Method: This study is a secondary analysis (Baker et al., 2020). Adults with PD were randomized to receive CBT + ABM (n = 11) or CBT + PBO (n = 12). Before each of the first five CBT sessions, CBT + ABM and CBT + PBO participants completed a 15‐min ABM task or attention training PBO, respectively. AS and depression severity as well as SC and EMG during habituation to a loud‐tone startle paradigm were assessed. Hierarchical Bayesian analyses were conducted. Results: During pre‐post‐treatment and pre‐follow‐up, CBM + ABM (vs. CBT + PBO) led to a notably greater reduction in ASI–Physical (between‐group d = −1.26 to −1.25), ASI‐Cognitive (d = −1.16 to −1.10), and depression severity (d = −1.23 to −0.99). However, no between‐group difference was observed for ASI‐Social, EMG, or SC indices. Discussion: Adding a brief computerized ABM intervention to CBT for PD protocols may enhance therapeutic change.

Aims: Assess effectiveness of a hybrid intervention targeting physical activity in women with prior gestational diabetes. Methods: Randomised controlled trial with parallel arms. 293 women (35.1 ± 5.1 years; 40% ethnic minority) recruited from two hospitals and randomised to routine care or hybrid lifestyle intervention comprising two group sessions and access to a mobile web app. Primary outcome was a change in objectively measured physical activity at 12 months. Secondary outcomes included self‐efficacy for exercise, quality of life and anxiety and depression. Linear regression compared outcome measures between groups. Results: 83% of intervention participants attended at least one group session, of who 66% registered to use the app. There was a non‐significant increase in physical activity at 12 months (between‐group difference of 0.95 mg [95% CI: −0.46 to 2.37]), equivalent to approximately 500 steps per day. Intervention participants reported higher self‐efficacy for exercise (0.54, 95% CI: 0.05 to 1.102; p = 0.029), lower anxiety (−0.91, 95% CI: −1.74 to −0.09; p = 0.031), and higher quality of life (0.05, 95% CI: 0.004 to 0.09; p = 0.032), compared to controls. Conclusions: The intervention improved confidence in exercise and quality of life. Further research is needed to improve participant engagement with physical activity interventions in multi‐ethnic populations with a history of gestational diabetes. [ABSTRACT FROM AUTHOR]

Objectives: There is limited understanding of change processes and long‐term effects of low‐intensity psychosocial interventions. We investigated these aspects in two brief problem‐solving intervention formats for adolescents with elevated mental health symptoms and associated distress/impairment. Methods: This qualitative study was nested within a school‐based randomized controlled trial in New Delhi, India, which compared two problem‐solving intervention formats: a lay counsellor‐led format supported by printed materials (intervention arm) and printed problem‐solving materials alone ("bibliotherapy" control arm). A total of 32 participants, ranging in age from 14 to 20 years (mean = 16.4 years, SD = 1.9) and comprising 21 males and 11 females, were interviewed across both trial arms at 12‐month follow‐up. Results: Five themes were derived using thematic framework analysis. The "impacts on symptoms and functioning" theme described symptomatic improvements and functional gains. "Processes underlying problem solving" reflected changes in positive beliefs, attitudes and emotions when confronted with problems, and the use of a more effective problem‐solving coping style. "Experiences of problem‐solving materials" covered benefits (e.g. access to relatable stories and readymade solutions) and limitations (e.g. diminishing use over time) of printed problem‐solving handouts. "Role of supporting figures" accounted for the facilitating roles played by counsellors and trusted others. There were also accounts of researchers functioning as de facto counsellors in the bibliotherapy arm. "Recommended modifications for intervention delivery" included more flexible and private ways to access the interventions, greater personalization of the counselling process, more engaging and relevant supporting materials, and suggestions for widening access to the interventions in schools and community settings. Conclusions: We infer from our qualitative analysis that changes in problem‐solving style and problem orientation underpinned long‐term symptomatic and functional improvements. Participants in the counsellor‐led intervention appeared better able to sustain the use of problem‐solving skills and generalize this approach beyond the original presenting problems. We attribute the differences between arms to the influence of direct advice and supportive interactions with counsellors. Practice implications are discussed. [ABSTRACT FROM AUTHOR]

Aims: To examine the effects of e‐learning on intimate partner violence (IPV) knowledge, preparatory/reinforcing behaviors for supporting IPV victims, and IPV screening of midwives and nurses. Methods: Participants were randomly assigned to the intervention group (IG: e‐learning) and control group (CG: no e‐learning). The primary outcome was the mean change in knowledge score. The secondary outcomes were the mean number of types of practiced preparatory/reinforcing behaviors and the proportions of participants who practice screening. Unpaired t tests were performed in intention‐to‐treat analysis. Results: Of the 88 participants, 45 were randomly assigned to the IG and 43 to the CG. For the post‐1‐test, the IG had a mean change in the knowledge score of 8.5 points with a significant difference from the 1.4 points in the CG (mean difference [MD] 7.1, 95% CI [4.1, 10.1]). The mean change between the pre‐test and the post‐2‐test was significantly larger in the IG (7.9 points) than in the CG (1.3 points) (MD 6.6, 95% CI [3.3, 9.9]). The mean number of types of practiced behaviors at the post‐1‐test and post‐2‐test was significantly higher in the IG than in the CG (MD 1.4, 95% CI [0.1, 2.8]). There was no significant difference in the proportions of participants who practice screening between the two groups postintervention. Conclusions: The e‐learning effectively improved knowledge and promoted preparatory/reinforcing behaviors. [ABSTRACT FROM AUTHOR]

Background: Older adults and their caregivers often believe it is either too late or too difficult to make health‐focused lifestyle changes. However, this is inaccurate, as older adults can make health promotion focused lifestyle changes thereby improving their health. This study developed and evaluated a self‐care education program using Pender's Health Promotion Model and its influence on health‐focused behaviour changes among older Iranians. Method: This was a quasi‐experimental study with a convenience sample of 136 community‐living older adults from Tabriz, Iran. The participants were randomly assigned to either an intervention (n = 69) or control (n = 67) group. Chi‐square test, independent t tests and Analysis of covariance (ANCOVA) statistical methods were used to compare pre‐ and post‐intervention data, control and intervention groups and changes over time. The intervention was an eight‐week educational program with pre‐ and post‐intervention data collected using the Health Promoting Lifestyle Profile II (HPLP II) questionnaire. Results: The mean difference and confidence limits of the older adults' health behaviours pre‐ and post‐intervention scores were 2.228 (−5.450 – 9.916) and ‐ 35.820 (−32.051 – 39.588). The covariance analysis adjusting for the baseline values showed significant differences post‐intervention (p<0.0001) in the areas of interpersonal communication, physical activity, nutrition, stress management and spiritual growth. Conclusion: The health promotion education intervention illustrated that older Iranians could improve their health outcomes in several areas. Thus, culturally tailored intervention programs can be successful in challenging the opinion that older adults cannot make behaviour changes supporting their health. [ABSTRACT FROM AUTHOR]

A cluster randomized trial design was used to test the efficacy of a behaviour change communication intervention on the quality of the home environment and infant development at 15 months of age. Children (n = 600) in rural South India were followed from 3 through 15 months of age. The control group (C group) received the standard of care, the complementary feeding group (CF group) received recommendations on complementary foods and the responsive complementary feeding and play group (RCF&P group) received recommendations on complementary foods plus skills on responsive feeding and play. The intervention was delivered in biweekly home visits to caregivers using flip charts. At postintervention, infants (n = 521) were assessed for development (Bayley‐II scales) and their home environment was assessed (Home Observation for Measurement of the Environment [HOME] scale). Cluster adjusted analysis of variance showed no significant differences at baseline. The HOME score at 15 months differed by group, F(2, 38) = 6.41, P = 0.004; the CF and RCF&P groups had higher scores than the C group. Scores on subscales 'Opportunities for Variety in Daily Stimulation' and 'Caregiver Promotion of Child Development' (CPCD) were higher for the RCF&P group than for the C and CF groups. Mental development index (MDI) scores differed by group, F(2, 37) = 3.31, P = 0.04, with the RCF&P group showing higher scores than the C group (P < 0.04); no differences were noted in psychomotor development index (PDI) scores (P = 0.48). The subscales of HOME associated with MDI at 15 months were 'CPCD' and 'Cleanliness of Child' (R2 = 0.076). 'CPCD' was also associated with PDI (R2 = 0.039). A responsive complementary feeding and play intervention delivered through home visits benefitted children's mental development and caregiving environment at 15 months. [ABSTRACT FROM AUTHOR]

Objective: To measure the impact of a 6‐month home‐based behaviour change intervention on reducing the risk of chronic disease as determined by metabolic syndrome status and cardiovascular risk score, and discuss implications for primary care in rural areas. Design: A two‐arm randomised controlled trial of rural adults. Setting: The rural town of Albany in the Great Southern region of Western Australia. Participants: Participants (n = 401) aged 50‐69 years who were classified with or at risk of metabolic syndrome and randomly assigned to intervention (n = 201) or waitlisted control (n = 200) group. Interventions: A 6‐month intervention program incorporating goal setting, self‐monitoring and feedback, with motivational interviewing was conducted. Main outcome measures: Change in metabolic syndrome status and cardiovascular risk. Results: Significant improvements in metabolic syndrome status and cardiovascular disease risk score (−0.82) were observed for the intervention group relative to control group from baseline to post‐test. Conclusion: This home‐based physical activity and nutrition intervention reduced participants' risk of experiencing a cardiovascular event in the next 5 years by 1%. Incorporating such prevention orientated approaches in primary care might assist in reducing the burden of long‐term chronic diseases. However, for realistic application in this setting, hurdles such as current national health billing system and availability of resources will need to be considered. [ABSTRACT FROM AUTHOR]

This study evaluated the effects of two treatments for adolescent bulimia nervosa (BN), family‐based treatment (FBT‐BN), and cognitive behavioral therapy (CBT‐A), on both attitudinal and behavioural outcomes at end‐of‐treatment. These associations were examined specifically relative to motivation for change in obsessive–compulsive (OC) features of eating disorder (ED) symptoms. Adolescents (N = 110) were randomly assigned to FBT‐BN or CBT‐A and completed assessments of eating pathology and OC‐ED behaviour. Across both treatments, greater motivation for change in OC‐ED behaviour was associated with improved attitudinal features of ED at end‐of‐treatment. Motivation for change did not demonstrate a direct or interaction effect on BN behavioural outcomes. Results suggest that adolescents with BN who are more motivated to change OC‐ED behaviours at the start of treatment, FBT‐BN or CBT‐A, are more likely to demonstrate improvements in cognitions, but not behaviours associated with EDs, at treatment conclusion.

Background Spousal concordance on risk factors and lifestyle habits exists and can partly be explained by patients' and spouses' health beliefs and underuse of cardiac rehabilitation. However, there have been very few qualitative comparisons of health beliefs between patients and spouses after a cardiac event. Aim To examine and qualitatively compare the health beliefs of patients with coronary heart disease and their spouses about lifestyle habits, 1 year after the cardiac event. Design Explorative and descriptive. Method Semi-structured focus group interviews were conducted with patients (n = 14) 1 year after a cardiac event, as well as individual interviews with spouses (n = 8). The transcriptions underwent a deductive qualitative content analysis, within the framework of the Health Belief Model. Findings Patients' and spouses' health beliefs about lifestyle habits qualitatively differed in most predetermined main analytical categories of the Health Belief Model. The patients relied more on their own capacity and the healthcare system than on collaboration with their spouses who instead emphasised the importance of mutual activities to establish lifestyle habits. The spouses therefore experienced problems with different family preferences compared to the patients' wishes. Moreover, only patients believed supervised exercise was beneficial for risk reduction of coronary heart disease and they related barriers for medication to a self-healing body and a meaningless life without relatives and old habits. Patients and spouses agreed that despite the severity of illness, life was captured and that normalisation to a life as usual was possible. Conclusion The patients' and spouses' qualitatively different health beliefs regarding health-related behaviours imply a new approach. Nurses and associated professionals need to follow-up patients' and spouses' in primary health care to support them in a tailored way, for example in problem-based sessions. Recognition and understanding of their different views and otherness could lead to compromises and goals to work with. [ABSTRACT FROM AUTHOR]

Purpose Physical restraints are used frequently in Korea, suggesting a growing need for access to programs focused on reduction. The aim of this study was to evaluate the effects of a multicomponent restraint reduction program (MRRP) for nursing staff in Korean nursing homes. Design A cluster-randomized, single-blind, controlled pretest-posttest design was used. A total of 122 nursing staff (nurses and geriatric care assistants) in two Korean nursing homes participated in this study: 62 in the experimental group (EG) and 60 in the control group (CG). Methods Nursing staff in the EG home received the MRRP comprising three educational sessions (two classroom-based and one web-based) and two unit-based consultations. Three instruments were used to measure nursing staff's knowledge, perceptions, and attitudes regarding physical restraints. Data were collected immediately before and after the intervention, and again 1 and 3 months later. Findings Repeated measures analysis of variance showed significant differences between groups in knowledge ( p < .001), perceptions ( p < .001), and attitudes ( p = .011) over time. These significant improvements in the MRRP group (EG) were sustained over the 3-month period. Conclusions The MRRP effectively improved the knowledge, perceptions, and attitudes of nursing home staff about restraint use with older adults. Additional studies are recommended to evaluate effects of its components while using larger samples and rigorous research methods and measurements, and the inclusion of boosters or other supports to sustain change. Clinical Relevance These results provide valuable knowledge regarding a multicomponent intervention for changing nursing home staff attributes that likely influence clinical practice. Elements of the educational content and methods found useful for nursing home staff may also be effective in vocational and continuing education as well as for families of older nursing home residents.

Objectives To assess the utility of a long-term physical activity ( PA) intervention for reducing resting pulse rate ( RPR) in older persons. Design Community. Setting Lifestyle Interventions and Independence for Elders Study. Participants Individuals aged 70 to 89 (N = 1,635, 67.2% women) were randomized to a moderate-intensity PA intervention (n = 818) or a health education-based successful aging ( SA) intervention (n = 817). Measurements RPR was recorded at baseline and 6, 18, and 30 months. Longitudinal changes in RPR of intervention groups were compared using a mixed-effects analysis of covariance model for repeated-measure outcomes, generating least squares means with standard errors ( SEs) or 95% confidence intervals ( CIs). Results Mean duration of the study was 2.6 years (median 2.7 years, interquartile range 2.3-3.1 years). The average effect of the PA intervention on RPR over the course of the study period was statistically significant but clinically small (average intervention difference = 0.84 beats/min; 95% CI = 0.17-1.51; Paverage = .01), with the most pronounced effect observed at 18 months ( PA, 66.5 beats/min ( SE 0.32 beats/min); SA, 67.8 beats/min ( SE 0.32 beats/min); difference = 1.37 beats/min, 95% CI = 0.48-2.26 beats/min). The relationship became somewhat weaker and was not statistically significant at 30 months. There were no significant differences between several prespecified subgroups. Conclusion A long-term moderate-intensity PA program was associated with a small and clinically insignificant slowing of RPR in older persons. Whether PA can deliver a beneficial reduction in RPR requires further examination in older adults. [ABSTRACT FROM AUTHOR]

ABSTRACT BACKGROUND Bullying behavior in schools can lead to psychosocial problems. School-based interventions are important in raising student awareness, developing their skills and in planning to reduce bullying behavior. METHODS A randomized controlled trial, using a school-based educational intervention to reduce verbal bullying, was conducted among grade 10 students in 16 urban and rural schools in KwaZulu-Natal, South Africa in 2013. Baseline and postintervention questionnaires, developed using the Integrated Model for Behavior Change theoretical model, were used to assess changes in verbal bullying. RESULTS Postintervention there were reduced verbal bullying experiences. Improved social norms and awareness of verbal bullying were associated with reduced verbal bullying experiences and behavior. Although less likely to bully others verbally, girls were more likely to experience verbal bullying. Students with no living father were more likely to bully others verbally. CONCLUSIONS The study findings indicate that a school-based intervention can positively impact on verbal bullying experiences and behavior. [ABSTRACT FROM AUTHOR]

The pathways through which behavior change interventions impact breastfeeding practices have not been well studied. This study aimed to examine: (1) the effects of exposure to mass media and interpersonal counseling on exclusive breastfeeding (EBF) and hypothesized psychosocial determinants (i.e. knowledge, intention, beliefs, social norms, and self‐efficacy); and (2) the pathways through which exposure to mass media and interpersonal counseling are associated with EBF. We used survey data from mothers with children < 2 year (n = 2045) from the 2013 process evaluation of Alive & Thrive's program in Viet Nam. Multiple linear regression analyses and structural equation modeling were used to estimate effects. Exposure to mass media only, interpersonal counseling only, both or neither was 51%, 5%, 19% and 25%, respectively. Exposure to both mass media and interpersonal counseling had additive effects on EBF as well as on related psychosocial factors, compared with no exposure. For example, EBF prevalence was 26.1 percentage points (pp) higher in the group that received interpersonal counseling only, 3.9 pp higher in the mass media group and 31.8 pp higher in the group that received both interventions. As hypothesized, more than 90% of the total effect of the two interventions on EBF was explained by the psychosocial factors measured. Our findings suggest that combining different behavior change interventions leads to greater changes in psychosocial factors, which in turn positively affects breastfeeding behaviors.

Aims To determine whether the provision of contingencymanagement using financial incentives to improve hepatitis B vaccine completion in people who inject drugs entering community treatment represents a cost-effective use of healthcare resources. Design A probabilistic cost-effectiveness analysis was conducted, using a decision-tree to estimate the short-term clinical and health-care cost impact of the vaccination strategies, followed by a Markov process to evaluate the long-term clinical consequences and costs associated with hepatitis B infection. Settings and participants Data on attendance to vaccination from a UK cluster randomized trial. Intervention Two contingency management options were examined in the trial: fixed versus escalating schedule financial incentives. Measurement Life-time health-care costs and quality-adjusted life years discounted at 3.5% annually; incremental cost-effectiveness ratios. Findings The resulting estimate for the incremental life-time health-care cost of the contingency management strategy versus usual care was £21.86 [95% confidence interval (CI) = -£12.20 to 39.86] per person offered the incentive. For 1000 people offered the incentive, the incremental reduction in numbers of hepatitis B infections avoided over their lifetime was estimated at 19 (95% CI = 8-30). The probabilistic incremental cost per quality adjusted life-year gained of the contingency management programmewas estimated to be £6738 (95% CI = £6297-7172),with an 89% probability of being considered cost-effective at a threshold of £20 000 per quality-adjusted life years gained (97.60% at £30 000). Conclusions Using financial incentives to increase hepatitis B vaccination completion in people who inject drugs could be a cost-effective use of health-care resources in the UK as long as the incidence remains above 1.2%.

Objectives To determine whether moderate-intensity physical activity ( PA) and health education ( HE) are differentially associated with categories of hospitalizations or subgroups of participants. Design Multicenter randomized controlled trial in which participants were randomized to a PA or HE program for an average of 2.6 years. Setting Eight field centers. Participants Sedentary men and women aged 70-89 with lower extremity physical limitations but able to walk 400-m in 15 minutes or less (N = 1,635). Interventions Structured, moderate-intensity PA (n = 818) at a center (2×/wk) and at home (3-4×/wk) that included aerobic, strength, balance, and flexibility training or HE (n = 817) of educational workshops and upper extremity stretching exercises. Measurements All-cause inpatient hospitalizations ascertained at 6-month intervals. Results There were 1,458 hospitalizations (49.1% of PA, 44.4% of HE; risk difference = 4.68%, 95% confidence interval ( CI) = −0.18-9.54; hazard ratio ( HR) = 1.16, 95% CI = 1.00-1.34). The intervention effect on incident hospitalization did not differ according to race, sex, Short Physical Performance Battery score, age, or history of cardiovascular disease or diabetes mellitus. PA was associated with higher rates of hospitalization in the middle baseline gait speed category, than HE (<0.8 m/s: HR = 0.93, 95% CI = 0.76-1.14; 0.8-1.0 m/s: HR = 1.54, 95% CI = 1.23-1.94; >1.0 m/s: HR = 1.05, 95% CI = 0.67-1.65; interaction P = .005). Conclusion A PA program in older adults at risk for mobility disability did not lead to a different risk of specific types of hospitalizations than a HE program overall. Baseline gait speed may be a marker for risk of hospitalization during a PA intervention, because individuals with moderate baseline gait speed in the PA group had slightly higher rates of hospitalization than those in the HE group.

Purpose: The prevalence of obesity in rural and remote areas is elevated in comparison to urban populations, highlighting the need for interventions targeting obesity prevention in these settings. Implementing evidence‐based obesity prevention programs is challenging. This study aimed to investigate factors influencing the implementation of obesity prevention programs, including adoption, program delivery, community uptake, and continuation, specifically within rural settings. Methods: Nested within a large‐scale randomized controlled trial, a qualitative exploratory approach was adopted, with purposive sampling techniques utilized, to recruit stakeholders from 41 small rural towns in Australia. In‐depth semistructured interviews were conducted with clinical health professionals, health service managers, and local government employees. Open coding was completed independently by 2 investigators and thematic analysis undertaken. Findings: In‐depth interviews revealed that obesity prevention programs were valued by the rural workforce. Program implementation is influenced by interrelated factors across: (1) contextual factors and (2) organizational capacity. Key recommendations to manage the challenges of implementing evidence‐based programs focused on reducing program delivery costs, aided by the provision of a suite of implementation and evaluation resources. Informing the scale‐up of future prevention programs, stakeholders highlighted the need to build local rural capacity through developing supportive university partnerships, generating local program ownership and promoting active feedback to all program partners. Conclusion: We demonstrate that the rural workforce places a high value on obesity prevention programs. Our results inform the future scale‐up of obesity prevention programs, providing an improved understanding of strategies to optimize implementation of evidence‐based prevention programs.

The objective of this study was to design, implement and evaluate an intervention based on the theory of planned behaviour (TPB) to enhance young peoples' motivations to breastfeed/support a partner to breastfeed. Six semi‐structured focus groups were first conducted with 48 13–14‐year‐olds from two schools in Northern Ireland. The salient beliefs elicited were subsequently used to design a TPB‐based questionnaire that was then administered to 2021 13–14‐year‐old pupils (852 males; 1169 females) from 36 post‐primary schools to identify the most important determinants of breastfeeding. The results were used to inform the design and implementation of an intervention package that was subsequently evaluated using a cluster randomised controlled trial involving 44 randomly selected schools across Northern Ireland. Questionnaires were administered to 18 intervention and 26 control schools at baseline and again at 1 and 6 months post‐intervention to evaluate its effectiveness. Multi‐level modelling was employed to analyse the data. The results revealed significant effects on women's intention to breastfeed, β = 0.208, t(1275) = 2.715, P = 0.007; attitudes, β = 0.223, t(1275) = 4.655, P < 0.001; moral attitudes, β = 0.231, t(1275) = 4.211, P < 0.001; subjective norm, β = 0.118, t(1275) = 2.521, P = 0.012; and knowledge, β = 0.109, d.f. (1275) = 7.843, P < 0.001. However, for men, the results revealed significant effects on only the construct of knowledge, β = 0.104, t(541) = 4.345, P < 0.001.The research has provided evidence to support the need for breastfeeding education in schools and has shown how a theoretical framework may be used to inform the design and evaluation of a health behaviour intervention.

Background Insufficient evidence exists to support obesity prevention in paediatric primary care. Objectives To test a theory-based behaviour modification intervention delivered by trained paediatric primary care providers for obesity prevention. Methods Efficacy trial with cluster randomization (practice level) and a 12-session 12-month sweetened beverages decrease intervention or a comprehensive dietary and physical activity intervention, compared with a control intervention among children ages 8-12 years. Results A low recruitment rate was observed. The increase in body mass index z-score ( BMIz) for the 139 subjects (11 practices) randomized to any of the two obesity interventions (combined group) was less than that of the 33 subjects (five practices) randomized to the control intervention (−0.089, 95% confidence interval [ CI]: −0.170 to −0.008, P = 0.03) with a −1.44 kg weight difference (95% CI: −2.98 to +0.10 kg, P = 0.095). The incidences of obesity and excess weight gain were lower in the obesity interventions, but the number of subjects was small. Post hoc analyses comparing the beverage only to the control intervention also showed an intervention benefit on BMIz (−0.083, 95% CI: −0.165 to −0.001, P = 0.048). Conclusions For participating families, an obesity prevention intervention delivered by paediatric primary care clinicians, who are compensated, trained and continuously supported by behavioural specialists, can impact children's BMIz.

ABSTRACT Objective Graded body image exposure is a key component of CBT for eating disorders (EDs). However, despite being a highly anxiety-provoking intervention, its specific effectiveness is unknown. The aims of this initial study were to investigate the feasibility and preliminary effectiveness of individualized graded body image exposure to a range of feared/avoided body image-related situations in a sample of partially remitted ED patients. Method Forty-five female adult participants were randomly assigned to maintenance treatment as usual (MTAU) only or MTAU plus five sessions of graded body image exposure. Results The graded body image exposure intervention led to large improvements in body avoidance as measured by two different methods. In addition, there was evidence of a significant impact of body image exposure on the overvaluation of shape, but not weight, 5 months after treatment. Discussion Taken together, the current results provide evidence of the feasibility of adjunctive individualized graded body image exposure within a clinical treatment program and suggest that graded body image exposure reduces body avoidance behaviors in partially remitted ED patients. Our findings suggest that individualized graded body image exposure shows promise as an intervention targeting the overvaluation of shape in EDs. © 2014 Wiley Periodicals, Inc.

Objectives To assess the effects of CBT on electroencephalogram activity in patients with orthodontic pain. Methods We recruited 24 young (18-28 years), healthy individuals with matched baseline characteristics, including pain intensity, anxiety levels, personality traits, and life-quality scores. Participants were randomly assigned to either the CBT intervention group ( n = 12) or the blank control group ( n = 12). Multichannel continuous electroencephalogram signals and visual analog scale ( VAS) scores were recorded before and after initial archwire placement for 1 week. A 1-month follow-up was conducted, when participants' daily VAS scores were recorded. Results The overall EEG spectral power of the CBT group was lower than that of the control group, especially in the theta (4-7 Hz) and beta (14-30 Hz) bands during the treatment period. An enhanced coupling of theta and beta frequencies was observed in frontal and occipital electrodes, respectively. The EEG power in delta and theta bands correlated positively with pain intensity. Network coherence for the CBT group exhibited higher connectivity in the theta band. Conclusions Specific cerebral responses to CBT instructions could be detected with continuous electroencephalograms and related to orthodontic pain processing, which may provide a new insight in exploring CBT for orthodontic pain control.

Background Failure to return to pregnancy weight by 6 months postpartum is associated with long-term obesity, as well as adverse health outcomes. This research evaluated a postpartum weight management programme for women with a body mass index ( BMI) > 25 kg m-2 that combined behaviour change principles and a low-intensity delivery format with postpartum nutrition information. Methods Women were randomised at 24-28 weeks to control (supported care; SC) or intervention (enhanced care; EC) groups, stratified by BMI cohort. At 36 weeks of gestation, SC women received a 'nutrition for breastfeeding' resource and EC women received a nutrition assessment and goal-setting session about post-natal nutrition, plus a 6-month correspondence intervention requiring return of self-monitoring sheets. Weight change, anthropometry, diet, physical activity, breastfeeding, fasting glucose and insulin measures were assessed at 6 weeks and 6 months postpartum. Results Seventy-seven percent (40 EC and 41 SC) of the 105 women approached were recruited; 36 EC and 35 SC women received a programme and 66.7% and 48.6% completed the study, respectively. No significant differences were observed between any outcomes. Median [interquartile range ( IQR)] weight change was EC: −1.1 (9.5) kg versus SC: −1.1 (7.5) kg (6 weeks to 6 months) and EC: +1.0 (8.7) kg versus SC: +2.3 (9) kg (prepregnancy to 6 months). Intervention women breastfed for half a month longer than control women (180 versus 164 days; P = 0.10). An average of 2.3 out of six activity sheets per participant was returned. Conclusions Despite low intervention engagement, the high retention rate suggests this remains an area of interest to women. Future strategies must facilitate women's engagement, be individually tailored, and include features that support behaviour change to decrease women's risk of chronic health issues.

Objective This is a secondary analysis of a randomized clinical trial which aims to examine changes in cognitive and behavioral responses to migraine with cognitive behavioral treatment for migraine, preventive medication for migraine, and their combination, and the relationship between these changes and reductions in migraine-related disability. Background Cognitive behavioral treatment is thought to reduce migraine-related disability through modifying maladaptive cognitive and behavioral responses to migraine. Methods Two hundred thirty-two people with migraine who did not respond to 5 weeks of optimized acute therapy were randomized into a 2 (beta-blocker vs placebo) X 2 (behavioral migraine management [ BMM] vs no BMM) treatment design. Participants received BMM and/or beta-blocker dose adjustment for 4 months, and were followed for an additional 12 months. Participants completed measures of catastrophizing, behavioral coping, and migraine-related disability throughout the study. Results Compared to drug therapy only, BMM demonstrated larger decreases in catastrophizing scores (19.16 to 9.89 vs 16.78 to 11.84, P < .001) and increases in number of positive coping strategies (proactive: 1.09 to 1.90 vs 1.16 to 1.09, P < .001; anticipatory: 0.19 to 0.69 vs 0.10 to 0.08, P < .001; migraine management: 0.14 to 0.36 vs 0.04 to 0.04, P < .001) at the end of the follow-up period. Decreases in catastrophizing were associated with a larger BMM effect on migraine-related disability ( P = .036). Conclusions This study demonstrated that BMM modified important cognitive and behavioral factors postulated to be mechanisms of cognitive behavioral treatments for migraine. [ABSTRACT FROM AUTHOR]

What is already known about this subject Obesity-related insulin resistance is highly prevalent in children and adolescents, and contributes to an increased lifetime risk of type 2 diabetes mellitus and cardiovascular disease., Intensive exercise training may improve insulin sensitivity., What this study adds Three monitored exercise training sessions per week for 8 weeks can improve fitness-related insulin sensitivity in obese, insulin resistant children., Insulin sensitivity and skeletal muscle oxidative phosphorylation may be dissociable in this population., Improvements in fitness may be accompanied by a rise in intramyocellular lipid content and an associated increase in resting energy expenditure., Background Obesity is associated with poor fitness and adverse metabolic consequences in children. Objective To investigate how exercise and lifestyle modification may improve fitness and insulin sensitivity in this population. Design and subjects Randomized controlled trial, 21 obese (body mass index ≥ 95% percentile) subjects, ages 10 to 17 years. Methods Subjects were given standardized healthful lifestyle advice for 8 weeks. In addition, they were randomized to an in-home supervised exercise intervention ( n = 10) or control group ( n = 11). Measurements Fasting laboratory studies (insulin, glucose, lipid profile) and assessments of fitness, body composition, skeletal muscle oxidative phosphorylation and intramyocellular lipid content ( IMCL), were performed at baseline and study completion. Results Subjects were 13.0 ± 1.9 (standard deviation) years old, 72% female and 44% non-white. Exercise improved fitness ( P = 0.03) and power ( P = 0.01), and increased IMCL ( P = 0.02). HOMA-IR decreased among all subjects in response to lifestyle modification advice ( P = 0.01), regardless of exercise training assignment. In univariate analysis in all subjects, change in cardiovascular fitness was associated with change in HOMA-IR. In exploratory analyses, increased IMCL was associated with greater resting energy expenditure (r = 0.78, P = 0.005) and a decrease in fasting respiratory quotient (r = −0.70, P = 0.02) ( n = 11). Conclusions Change in fitness was found to be related to change in insulin resistance in response to lifestyle modification and exercise in obese children. IMCL increased with exercise in these obese children, which may reflect greater muscle lipid oxidative capacity. [ABSTRACT FROM AUTHOR]

The UK has low breastfeeding rates, with socioeconomic disparities. The Assets‐based feeding help Before and After birth (ABA) intervention was designed to be inclusive and improve infant feeding behaviours. ABA is underpinned by the behaviour change wheel and offers an assets‐based approach focusing on positive capabilities of individuals and communities, including use of a Genogram. This study aimed to investigate feasibility of intervention delivery within a randomised controlled trial (RCT). Nulliparous women ≥16 years, (n = 103) from two English sites were recruited and randomised to either intervention or usual care. The intervention – delivered through face‐to‐face, telephone and text message by trained Infant Feeding Helpers (IFHs) – ran from 30‐weeks' gestation until 5‐months postnatal. Outcomes included recruitment rates and follow‐up at 3‐days, 8‐weeks and 6‐months postnatal, with collection of future full trial outcomes via questionnaires. A mixed‐methods process evaluation included qualitative interviews with 30 women, 13 IFHs and 17 maternity providers; IFH contact logs; and fidelity checking of antenatal contact recordings. This study successfully recruited women, including teenagers, from socioeconomically disadvantaged areas; postnatal follow‐up rates were 68.0%, 85.4% and 80.6% at 3‐days, 8‐weeks and 6‐months respectively. Breastfeeding at 8‐weeks was obtained for 95.1% using routine data for non‐responders. It was possible to recruit and train peer supporters to deliver the intervention with adequate fidelity. The ABA intervention was acceptable to women, IFHs and maternity services. There was minimal contamination and no evidence of intervention‐related harm. In conclusion, the intervention is feasible to deliver within an RCT, and a definitive trial required. [ABSTRACT FROM AUTHOR]
