Background Associations among illness perceptions of viruses, anxiety and depression symptoms, and self-management decisions, such as mask-wearing, are critical to informing public health practices to mitigate the short- and long-term consequences of the SARS-CoV-2 viral pandemic. Purpose Guided by the common-sense model of self-regulation, this observational study examined associations among illness perceptions of COVID-19, anxiety, and depression symptoms among community-dwelling adults. Method Data were collected from 1380 adults living in the United States early in the pandemic (03-23-2020 to 06-02-2020). Participants completed online surveys. Analyses were conducted using descriptive statistics and correlations. Findings While increased anxiety symptoms were associated with less perceived personal control, greater concern, and higher emotional responsiveness, increased depression symptoms were related to lower concern as well as greater emotional responsiveness and perceived consequences of the pandemic. Discussion Associations among illness perceptions, anxiety, and depression symptoms may impact viral spread mitigation behavior adoption.

Background Medication non-adherence is a problem of critical importance, affecting approximately 50% of all persons taking at least one regularly scheduled prescription medication and costing the United States more than $100 billion annually. Traditional data sources for identifying and resolving medication non-adherence in community pharmacies include prescription fill histories. However, medication possession does not necessarily mean patients are taking their medications as prescribed. Patient-reported outcomes (PROs), measuring adherence challenges pertaining to both remembering and intention to take medication, offer a rich data source for pharmacists and prescribers to use to resolve medication non-adherence. PatientToc™ is a PROs collection software developed to facilitate collection of PROs data from low-literacy and non-English speaking patients in Los Angeles. Objectives This study will evaluate the spread and scale of PatientToc™ from primary care to community pharmacies for the collection and use of PROs data pertaining to medication adherence. Methods The following implementation and evaluation steps will be conducted: 1) a pre-implementation developmental formative evaluation to determine community pharmacy workflow and current practices for identifying and resolving medication non-adherence, potential barriers and facilitators to PatientToc™ implementation, and to create a draft implementation toolkit, 2) two plan-do-study-act cycles to refine an implementation toolkit for spreading and scaling implementation of PatientToc™ in community pharmacies, and 3) a comprehensive, theory-driven evaluation of the quality of care, implementation, and patient health outcomes of spreading and scaling PatientToc™ to community pharmacies. Expected impact This research will inform long-term collection and use of PROs data pertaining to medication adherence in community pharmacies.

Context Most children with cancer die in hospital settings, without hospice, and many suffer from high-intensity medical interventions and pain at end of life (EOL). Objectives To examine the effects of COMPLETE: a communication plan early through EOL to increase hospice enrollment in children with cancer at EOL. Methods This is a two-phase, single-arm, two-center, and prospective pilot study of hospice enrollment in children with cancer whose parents received COMPLETE. COMPLETE is a series of medical doctor (MD)/registered nurse (RN)-guided discussions of goals of care using visual aids that begin at diagnosis. COMPLETE training for MD/RNs in Phase II was revised to increase their use of empathy. Preintervention/postintervention measurements for child include: time of hospice enrollment, pain, high-intensity medical interventions at EOL, and location of death; and for parent the following: uncertainty and hope. Results Twenty-one parents of 18 children enrolled in the study, and 13 children were followed through EOL. At EOL, 11 (84.6%) died on home hospice or inpatient hospice, and only two (15%) received high-intensity medical interventions. Similar to published findings in the initial 13 parents enrolled in Phase I, parents in Phase II (n = 7) had improvement in hope and uncertainty, and child pain was decreased. Revised training resulted in significant improvement in MD/RN (N = 6) use of empathy (11% in Phase I vs. 100% in Phase II; P = 0.001). Conclusion COMPLETE resulted in increased hospice enrollment in children with cancer at EOL compared with historical controls. In preanalysis/postanalysis, COMPLETE decreased child pain while supporting hope and reducing uncertainty in their parents.

Objective Parent variables (stigma, mood, unmet needs for information and support, and worry) are associated with behavioral difficulties in children with seizures; however, it is not known how this relationship is influenced by additional seizures. This study followed children (ages 4–14 years) and their parents over a 24-month period (with data collected at baseline and 6, 12, and 24 months) and investigated the effect of an additional seizure on the relationship between parenting variables and child behavior difficulties. Methods The sample was parents of 196 children (104 girls and 92 boys) with a first seizure within the past 6 weeks. Child mean age at baseline was 8 years, 3 months (SD 3 years). Data were analyzed using t-tests, chi-square tests, and repeated measures analyses of covariance. Results Relationships between parent variables, additional seizures, and child behavior problems were consistent across time. Several associations between parent variables and child behavior problems were stronger in the additional seizure group than in the no additional seizure group. Conclusions Findings suggest that interventions that assist families to respond constructively to the reactions of others regarding their child's seizure condition and to address their needs for information and support could help families of children with continuing seizures to have an improved quality of life.

Objectives Thymic malignancies are rare, and options are limited for metastatic disease. Src plays a role in normal thymic epithelial maturation, and its inhibition with the oral compound saracatinib was postulated to be effective in controlling thymic malignancy. Materials and methods Patients with unresectable thymic malignancy were treated with saracatinib 175 mg by mouth daily in 28 days cycles with radiographic evaluation at cycle 2 day 1 for safety, then cycle 3 day 1 and every 8 weeks thereafter. Response was evaluated by RECIST 1.0. A two-stage optimal design was used, powered to detect a true response rate of 20%. Results 21 patients were enrolled at two institutions, 12 of them with thymoma, 9 with thymic carcinoma. Thymoma patients received a median of 4.5 cycles and thymic carcinoma patients a median of 1 cycle. There were no responses, so accrual was halted after the first stage per protocol. 9 patients had stable disease beyond the first assessment. Median time to progression was 5.7 months for thymoma patients and 3.6 months for thymic carcinoma patients. Saracatinib was well tolerated. Conclusion Src inhibition by saracatinib did not produce any radiographic responses, though some patients did experience stable disease. Though negative, this study shows the feasibility of completing a trial in this rare disease, and of accruing reasonably significant numbers of thymic carcinoma patients. More clinical trials are required for this population ( NCT00718809 ).

Building Our Solutions and Connections (BOSC) focused on enhancing problem-solving skills (PSS) of primary caregivers of children with mental health problems. Aims were determining feasibility, acceptability, and effect size ( ES ) estimates for depression, burden, personal control, and PSS. Methods: Caregivers were randomized to BOSC ( n = 30) or wait-list control (WLC) groups ( n = 31). Data were collected at baseline, post-intervention, and 3 and 6 months post-intervention. Results: Three-months post-intervention, ES for burden and personal control were .07 and .08, respectively. ES for depressed caregivers for burden and personal control were 0.14 and 0.19, respectively. Conclusions: Evidence indicates that the intervention had desired effects.

Background Provider recommendation is a predictor of colorectal cancer (CRC) screening. Purpose To compare the effects of two clinic-based interventions on patient–provider discussions about CRC screening. Design Two-group RCT with data collected at baseline and 1 week post-intervention. Setting/participants African-American patients that were non-adherent to CRC screening recommendations ( n =693) with a primary care visit between 2008 and 2010 in one of 11 urban primary care clinics. Intervention Participants received either a computer-delivered tailored CRC screening intervention or a nontailored informational brochure about CRC screening immediately prior to their primary care visit. Main outcome measures Between-group differences in odds of having had a CRC screening discussion about a colon test, with and without adjusting for demographic, clinic, health literacy, health belief, and social support variables, were examined as predictors of a CRC screening discussion using logistic regression. Intervention effects on CRC screening test order by PCPs were examined using logistic regression. Analyses were conducted in 2011 and 2012. Results Compared to the brochure group, greater proportions of those in the computer-delivered tailored intervention group reported having had a discussion with their provider about CRC screening (63% vs 48%, OR=1.81, p p -values Conclusions The computer-delivered tailored intervention was more effective than a nontailored brochure at stimulating patient–provider discussions about CRC screening. Those who received the computer-delivered intervention also were more likely to have a CRC screening test (fecal occult blood test or colonoscopy) ordered by their PCP. Trial registration This study is registered at www.clinicaltrials.gov NCT00672828.

Objectives The purposes of this 36-month study of children with first recognized seizures were: (1) to describe baseline differences in behavior problems between children with and without prior unrecognized seizures; (2) to identify differences over time in behavior problems between children with seizures and their healthy siblings; (3) to identify the proportions of children with seizures and healthy siblings who were consistently at risk for behavior problems for 36 months; and (4) to identify risk factors for behavior problems 36 months following the first recognized seizure. Risk factors explored included demographic (child age and gender, caregiver education), neuropsychological (IQ, processing speed), seizure (epileptic syndrome, use of antiepileptic drug, seizure recurrence), and family (family mastery, satisfaction with family relationships, parent response) variables. Methods Participants were 300 children aged 6 through 14 years with a first recognized seizure and 196 healthy siblings. Data were collected from medical records, structured interviews, self-report questionnaires, and neuropsychological testing. Behavior problems were measured using the Child Behavior Checklist and the Teacher's Report Form. Data analyses included descriptive statistics and linear mixed models. Results Children with prior unrecognized seizures were at higher risk for behavior problems at baseline. As a group, children with seizures showed a steady reduction in behavior problems over time. Children with seizures were found to have significantly more behavior problems than their siblings over time, and significantly more children with seizures (11.3%) than siblings (4.6%) had consistent behavior problems over time. Key risk factors for child behavior problems based on both caregivers and teachers were: less caregiver education, slower initial processing speed, slowing of processing speed over the first 36 months, and a number of family variables including lower levels of family mastery or child satisfaction with family relationships, lower parent support of the child's autonomy, and lower parent confidence in their ability to discipline their child. Conclusions Children with new-onset seizures who are otherwise developing normally have higher rates of behavior problems than their healthy siblings; however, behavior problems are not consistently in the at-risk range in most children during the first 3 years after seizure onset. When children show behavior problems, family variables that might be targeted include family mastery, parent support of child autonomy, and parents’ confidence in their ability to handle their children's behavior.

Objectives Children with long-standing epilepsy have a significantly increased risk of academic underachievement compared with healthy controls. We prospectively followed children from seizure onset to assess the relationship between change in neuropsychological functioning and change in academic achievement and to explore the risk and protective moderating effects of demographic, seizure, and family variables. Methods As part of a larger study, neuropsychological and academic data were collected at both baseline and 36 months for 219 children 6–14 years of age with seizures. Prior factor analysis of results from a battery of well-standardized neuropsychological tests yielded four factors: language, processing speed, attention/executive/construction, and verbal memory/learning. Academic achievement was measured with the Woodcock–Johnson Revised Achievement Test Battery. Correlation coefficients and linear mixed models were used for analysis. Results The reading and math scores of children with seizures and siblings did not differ at baseline, but children with seizures had lower scores than siblings at 36 months. Writing scores were significantly lower for affected children than siblings at both times. Among children with seizures, there were positive correlations between neuropsychological functioning and academic achievement at baseline and 36 months. Changes in language and in verbal memory/learning were positively correlated with change in reading achievement ( r = 0.25 and r = 0.17, respectively). Age at onset moderated the association between change in neuropsychological functioning and change in reading and writing achievement ( P ≤ 0.006), with stronger relationships among younger children (β = 0.25–0.44). The association between change in language and change in writing achievement was moderated by caregiver anxiety ( P = 0.04; stronger for more anxious parents, β = 0.40), and the association between change in processing speed and change in math achievement was moderated by etiology ( P = 0.02; stronger for symptomatic/cryptogenic vs idiopathic, β = 0.29). Gender and other family variables did not have significant moderating effects. Conclusions Changes in neuropsychological function were associated with changes in academic achievement following onset of seizures, with risk factors being younger age at onset, lower caregiver education, high parental anxiety, and symptomatic/cryptogenic etiology. Academic performance should be closely monitored in children with early-onset seizures.

Background and purpose We report frequency of brachial plexopathy in early-stage non-small cell lung cancer treated with stereotactic body radiotherapy. Materials and methods 276 T1–T2, N0 or peripheral T3, N0 lesions were treated in 253 patients with stereotactic radiotherapy at Indiana University and Richard L. Roudebush VAMC from 1998 to 2007. Thirty-seven lesions in 36 patients were identified as apical lesions, defined as epicenter of lesion superior to aortic arch. Brachial plexus toxicity was scored for these apical lesions according to CTCAE v. 3.0 for ipsilateral shoulder/arm neuropathic pain, motor weakness, or sensory alteration. Results The 37 apical lesions (19 Stage IA, 16 IB, and 2 IIB) were treated with stereotactic body radiotherapy to a median total dose of 57Gy (30–72). The associated brachial plexus of 7/37 apical lesions developed grade 2–4 plexopathy (4 pts – grade 2, 2 pts – grade 3, 1 pt – grade 4). Five patients had ipsilateral shoulder/arm neuropathic pain alone, one had pain and upper extremity weakness, and one had pain progressing to numbness of the upper extremity and paralysis of hand and wrist. The median of the maximum brachial plexus doses of patients developing brachial plexopathy was 30Gy (18–82). Two-year Kaplan–Meier risk of brachial plexopathy for maximum brachial plexus dose >26Gy was 46% vs 8% for doses ⩽26Gy ( p =0.04 for likelihood ratio test). Conclusions Stereotactic body radiotherapy for apical lesions carries a risk of brachial plexopathy. Brachial plexus maximum dose should be kept

We have previously demonstrated that the EP1 subtype of PGE2 receptor is expressed in the differentiated compartment of normal human epidermis and is coupled to intracellular calcium mobilization. We therefore hypothesized that the EP1 receptor is coupled to keratinocyte differentiation. In in vitro studies, radioligand binding, RT-PCR, immunoblot and receptor agonist-induced second messenger studies demonstrate that the EP1 receptor is up-regulated by high cell density in human keratinocytes and this up-regulation precedes corneocyte formation. Moreover, two different EP1 receptor antagonists, SC51322 and AH6809, both inhibited corneocyte formation. SC51322 also inhibited the induction of differentiation-specific proteins, cytokeratin K10 and epidermal transglutaminase. We next examined the immunolocalization of the EP1 receptor in non-melanoma skin cancer in humans. Well differentiated SCCs exhibited significantly greater membrane staining, while spindle cell carcinomas and BCCs had significantly decreased membrane staining compared with normal epidermis. This data supports a role for the EP1 receptor in regulating keratinocyte differentiation.

This study characterized structural abnormalities associated with onset of seizures in children, using magnetic resonance imaging and a standardized classification system in a large prospective cohort. Two hundred eighty-one children aged 6-14 years completed magnetic resonance imaging within 6 months of their first recognized seizure. Most examinations were performed with a standardized, dedicated seizure protocol; all were scored using a standard scoring system. At least one magnetic resonance imaging abnormality was identified in 87 of 281 (31%) children with a first recognized seizure. Two or more abnormalities were identified in 34 (12%). The commonest abnormalities were ventricular enlargement (51%), leukomalacia/gliosis (23%), gray-matter lesions such as heterotopias and cortical dysplasia (12%), volume loss (12%), other white-matter lesions (9%), and encephalomalacia (6%). Abnormalities defined as significant, or potentially related to seizures, occurred in 40 (14%). Temporal lobe and hippocampal abnormalities were detected at a higher frequency than in previous studies (13/87). Magnetic resonance imaging and a standardized, reliable, valid scoring system demonstrated a higher rate of abnormal findings than previously reported, including findings formerly considered incidental. Practice parameters may need revision, to expand the definition of significant abnormalities and support wider use of magnetic resonance imaging in children with newly diagnosed seizures.

The aims of this study were to develop an instrument to measure parents' responses and perceptions related to the onset of either seizures or asthma in a child (aged 4-14) and to assess the initial reliability and validity of the instrument. The 35-item scale developed comprised five subscales: Child Support, Family Life/Leisure, Condition Management, Child Autonomy, and Child Discipline. Subjects were parents of 224 children with new-onset seizures and 104 parents of children with new-onset asthma. Internal consistency reliabilities were stronger for Child Support, Family Life/Leisure, and Condition Management than for Child Autonomy and Child Discipline for both samples. Test-retest reliability ranged from good to fair for both samples. The associations between parent positive mood and all of the subscales for both samples in the predicted directions provided key empirical support for validity. The scale has potential for use in research and in the clinical setting. In addition, the scale has potential to be used with other conditions.

Objective To evaluate the acceptability to Latino parents of having their adolescent children vaccinated against sexually transmitted infections, and to identify potential demographic correlates of acceptability. Methods We applied established methodology to a sample of 119 Latino parents who accompanied their children (51% female, aged 12–17 years) to medical appointments. The parents used computer-based questionnaires to rate 9 hypothetical vaccine scenarios. The scenarios had 4 dimensions: mode of transmission (sexually transmitted or not sexually transmitted), severity of infection (curable, chronic, or fatal), vaccine efficacy (50%, 70%, or 90%), and availability of behavioral methods for prevention (available or not available). Willingness by parents to vaccinate their adolescents under each vaccine scenario was assessed on a scale (range, 0–100). Conjoint analysis was used to determine the relative contribution of each dimension to the ratings. Results The study sample consisted of predominantly Mexican immigrant parents, 94% of whom chose to complete the Spanish version of the computerized interview. The mean value of the parents' willingness to accept vaccination for their adolescent children was exceptionally high. For example, the mean score of the Latino parents for the 6 sexually transmitted infection (STI) vaccine scenarios (score 86.2; SD 21.1) was far higher than the mean score in previous studies (81.3, SD 21.1). Conjoint analysis revealed that the dimensions of vaccine efficacy and severity of infection were equal in terms of their influence on vaccine ratings for the Latino parents. The next most influential dimension on vaccine ratings was the availability of behavioral prevention, followed by the sexual transmissibility of the infection. Conclusions Our sample of predominantly Mexican parents was accepting of the concept of STI vaccination for their adolescent children. Important issues for parents include vaccine efficacy and severity of infection, followed by vaccines for infections that had no method of behavioral prevention available. Overall, there is little difference in the relative preference of a STI versus non-STI vaccine for their adolescent children.

Background The treatment of primary mediastinal nonseminomatous germ cell tumors (PMNSGCT) with cisplatin-based chemotherapy, followed by surgical resection of residual disease, has been established. We reviewed our institution's 25-year experience in the cisplatin era to determine surgical risks and predictors of survival after surgery for PMNSGCT. Methods A total of 158 patients (mean age, 29 ± 8 years) who underwent postchemotherapy operations for PMNSGCT were reviewed and multiple variables analyzed. Results Ten (6%) operative deaths occurred, nine of which were attributed to respiratory failure, and 26 (18%) patients experienced postoperative complications, including 9 with respiratory failure. None of 17 recent patients who received chemotherapy regimens that did not contain bleomycin experienced pulmonary complications ( p = 0.12 vs patients who received bleomycin). Operative survivors were followed up a median of 34 months (range, 1 to 194 months). Multivariable analysis demonstrated that the postchemotherapy pathologic category of complete necrosis vs teratoma), persistent germ cell or nongerm cell cancer, and elevated serum tumor markers after operation were independently predictive of survival. Conclusions Operative risks for PMNSGCT appear to be improved with the use of chemotherapy regimens that do not contain bleomycin. Patients pathologically demonstrating complete tumor necrosis in the residual mass after chemotherapy have excellent long-term survival, with decreasing survival after resection of teratoma and persistent germ cell or nongerm cell cancer. Patients pathologically demonstrating persistent germ cell or nongerm cell cancer have poor but possible long-term survival, which justifies an aggressive surgical approach in patients who are deemed operable.

The purpose of this study was to compare teachers' ratings of academic performance over 24 months between children with new-onset seizures (N=121) and those with new-onset asthma (N=54) aged 4 to 14. At each data collection point (baseline, 12 months, 24 months), children with seizures were placed into two groups according to their recurrent seizure status (yes/no) during that period. Longitudinal linear mixed models were used to explore differences between the asthma group and the two seizure groups and to determine if differences in teachers' ratings of performance in children with seizures were associated with age, gender, or use of medication. In the seizure sample, scores for children in both groups (with and without recurrent seizures) initially declined at 12 months; however, at 24 months, children who did not have recurrent seizures improved, whereas children who continued to have recurrent seizures declined. There was a trend for younger children to decline more than older children.

Blood levels of the anti-inflammatory and cardioprotective omega-3 eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids are determined primarily by dietary consumption. There is reason to believe that hemodialysis patients are at risk for inadequate omega-3 intake and, consequently, low blood levels.This question was tested in 75 long-term hemodialysis patients and 25 matched controls by measuring fasting, predialysis plasma and red blood cell (RBC) fatty acid levels using gas chromatography and performing a fish-consumption survey.Sixty-seven percent of patients did not meet American Heart Association fish-consumption guidelines for healthy persons. Compared with controls, patients had lower plasma omega-3 levels (mean % wt: DHA, 1.33 +/- 0.38 [SD] versus 1.51 +/- 0.36; P = 0.0370; omega-3 index [ie, EPA plus DHA], 1.67 +/- 0.49 versus 1.92 +/- 0.40; P = 0.0249). RBC levels, which estimate more long-term consumption, showed mixed results (EPA, 0.29 +/- 0.08 versus 0.33 +/- 0.11; P = 0.0816; DHA, 4.65 +/- 0.92 versus 3.16 +/- 1.15; P0.0001; omega-3 index, 4.95 +/- 0.95 versus 3.49 +/- 1.22; P0.0001). RBC omega-3 levels in patients roughly reflected fish consumption. Independent predictors of plasma and RBC omega-3 levels at the 0.05 level of significance included age, race, sex, alcohol use, and fish servings.Hemodialysis patients consumed fish in quantities far below current American Heart Association recommendations and manifested suboptimal omega-3 levels given their high heart disease risk. These results identify a potentially modifiable cardiovascular risk factor.

Heart failure is nearing epidemic proportions and there is a need for innovative approaches to care that facilitate learning and behavioral change in order to improve health outcomes. This article discusses the development and pilot testing of the PUMP UP program, a tailored computerized intervention, designed to improve 4 health outcomes. The development phases included evaluation of knowledge and design and computerization of the intervention. Pilot testing was completed with 12 patients recruited from primary medicine clinics. Patients completed a baseline telephone interview; follow-up data were obtained immediately after the intervention clinic visit and at 4, 8, and 26 weeks after the visit. Four of the 12 patients met the outcome of improved provider adherence to guidelines. Health-related quality of life scores improved at 26 weeks after baseline. The PUMP UP program was informative and feasible to deliver. It is now ready for testing in intervention studies with larger samples.

Purpose. The goal of this work is to describe psychometric properties of two scales measuring perceived stigma in children with epilepsy and their parents. Methods. Data were collected for the parent scale in two samples: parents of 173 children with epilepsy and of 224 children with new-onset seizures. The child scale was tested in the chronic sample. Content validity, internal consistency reliability, and construct validity were tested. Results. Both scales had strong internal consistency reliability and construct validity. Higher scores were associated with greater seizure severity scores. In the parent scale, lower scores were associated with more positive mood, less worry, and more family leisure activities. In the child scale, higher scores were correlated with more negative attitude, greater worry, poorer self-concept, and more depression symptoms. Conclusions. Both scales were found to have strong psychometric properties. They are short, and items are easy to understand. These scales have potential for use in research and in the clinical setting to measure stigma. 2004 Elsevier Inc. All rights reserved.

Objective: The purpose of this study was to determine in a group of hemodialysis patients whether perceptions of barriers to and benefits of adherence to fluid limitations, perceived seriousness of and susceptibility to the consequences of nonadherence, self-efficacy, and thirst differed by stage of fluid adherence. Design: Cross-sectional descriptive design. Setting: There were 147 participants from rural, suburban, and urban outpatient hemodialysis units. Results: Significant differences were found in perceived benefits, barriers, seriousness, susceptibility, and thirst intensity by stage of fluid adherence. There were no significant differences in self-efficacy by stage of fluid adherence. Conclusion: Stage of fluid adherence may be important to consider when designing interventions to reduce fluid intake.

The purpose of this study was to explore the association between seizures and behavior problems in children with new-onset seizures using teachers' ratings of behavior. Subjects were 209 children with new-onset seizures and 93 children with asthma. Teacher ratings of behavior were collected prospectively over 24 months to determine differences between children with recurrent seizures, children without recurrent seizures, and children with asthma. During the 2-year period, 155 (74%) children had at least one recurring seizure. Data were analyzed using repeated-measures analysis of variance both with and without covariates. Controlling for covariates, children experiencing recurrent seizures had higher Total (P=0.002) and Internalizing (P=0.018) Behavior Problems scores across all times than those not experiencing recurrent seizures. Children with asthma were similar to children not experiencing recurrent seizures. The association between seizures and behavioral problems was supported using behavioral ratings from teachers.

Background: Lack of medication and dietary compliance leads to troublesome symptoms and hospitalization in patients with heart failure. Compliance behaviors are influenced by beliefs about the behavior. Objective: The purpose of this study was to evaluate the reliability and validity of the Beliefs about Medication Compliance Scale (BMCS) and the Beliefs about Dietary Compliance Scale (BDCS) among patients with heart failure. Theoretical Framework: This study’s theoretical framework is the Health Belief Model. Methods: A convenience sample of 234 patients with heart failure completed the BMCS and the BDCS. Patients completed the scales at baseline by face-to-face interviews and at 8 and 52 weeks after baseline by telephone interview. Results: Construct validity of the scales was supported by confirmatory factor analysis. Both the BMCS and the BDCS had benefits and barriers scales with clear factor loadings. The internal consistency reliability estimates of the scales ranged from.63 to.88, with the BMCS having some estimates lower than.70. The test-retest reliability estimates ranged from.07 to.57. The intraclass correlation coefficient estimates were higher between the 8-week and 52-week scores for all scales. Possible reasons for the varying estimates are discussed. Conclusions: The BMCS and the BDCS have documented reliability and validity. Future work should be directed at evaluating the responsiveness of the scales to changing patient conditions and testing interventions to improve medication and dietary compliance through changing beliefs.

Objectives To measure empirically the influence of race and socioeconomic status (SES) on the diagnosis of child abuse and willingness to report to child protection services. Study design A total of 5000 pediatricians randomly selected from the American Medical Association's Masterfile received 1 of 4 randomly assigned versions of a fictional clinical presentation of a child (black/white + high SES/low SES) that described an unwitnessed event in a mobile 18-month-old child resulting in an oblique femur fracture. Outcome measures included ranking the degree to which the injury was accidental versus abuse and agreement with reporting the injury to child protection services. Results A total of 2109 of 4423 physicians responded (47.7%). Patient's race did not have an effect on a diagnosis of abuse (black, 45% versus white, 46%). Abuse was more likely to be diagnosed in patients with low SES (48% versus 43%, overall P = .02). Conclusion This study supports earlier work demonstrating physicians' greater willingness to consider abuse as a potential cause of injury in low SES children. It failed to demonstrate the finding of retrospective, real world studies of an increased likelihood to consider abuse in black patients. Future work should try to understand why there remains a differential approach to evaluating minority children for abuse in real world settings.
