We developed the 16-item Patient-Reported Arthralgia Inventory (PRAI) to measure arthralgia severity in 16 joints, in the context of a longitudinal cohort study to assess aromatase inhibitor-associated arthralgia in breast cancer survivors and arthralgia in postmenopausal women without breast cancer. We sought to evaluate the reliability and validity of the PRAI instrument in these populations, as well as to examine the relationship of patient-reported morning stiffness and arthralgia. Methods: We administered the PRAI on paper in 294 women (94 initiating aromatase inhibitor therapy and 200 postmenopausal women without breast cancer) at weeks 0, 2, 4, 6, 8, 12, 16, and 52, as well as once in 36 women who had taken but were no longer taking aromatase inhibitor therapy. Results: Cronbach's alpha was 0.9 for internal consistency of the PRAI. Intraclass correlation coefficients of test-retest reliability were in the range of 0.87–0.96 over repeated PRAI administrations; arthralgia severity was higher in the non-cancer group at baseline than at subsequent assessments. Women with joint comorbidities tended to have higher PRAI scores than those without (estimated difference in mean scores: -0.3, 95% confidence interval [CI] -0.5, -0.2; P

The purpose of this study was to develop and validate two instruments: one to assess patient perceptions of control of the childbirth environment and the other, global satisfaction with the childbirth experience. Participants were 187 women recruited from obstetric clinics, breast-feeding support groups and online who had given birth in the past 4 months. Scale development involved item construction, exploratory factor analysis (EFA) of the Perceived Control in Childbirth Scale (PCCh), confirmatory factor analysis (CFA) of the Satisfaction with Childbirth Scale (SWCh), reliability analysis and construct validity analyses. EFA identified a single factor underlying a set of items reflecting the patient's belief that her actions influenced the birth environment (i.e. perceived control). CFAs supported a single-factor model reflecting the degree to which the birth experience met the patient's ideal (i.e. satisfaction). Perceived control was associated with childbirth self-efficacy. Childbirth satisfaction was associated with both affective reactions to birth and childbirth-related posttraumatic stress disorder (PTSD) symptoms. Results support the validity and reliability of two new scales that assess perceived control of the birth environment and global satisfaction with childbirth. [ABSTRACT FROM AUTHOR]

The mechanisms underlying the relationship between health literacy, numeracy, and glycemic control are unclear. We explored the role of diabetes self-efficacy in the predicted pathway linking health literacy and numeracy to glycemic control (A1C). Adults with type 1 or type 2 diabetes mellitus (N = 383) were enrolled in a cross-sectional study at primary care and diabetes clinics at three medical centers. Data collected included demographic information, health literacy, general numeracy, and A1C. Path models estimated relations among health literacy, numeracy, and diabetes self-efficacy as predictors of A1C. Health literacy (r = 0.14, p < .01) and numeracy (r = 0.17, p < .001) were each associated with greater diabetes self-efficacy, and greater diabetes self-efficacy was associated with lower A1C levels (r = -0.25, p < .001). When considered in combination, numeracy was related to diabetes self-efficacy (r = 0.13, p < .05), and the effect of health literacy on diabetes self-efficacy was reduced to non-significance (r = 0.06, p = .30). Health literacy and numeracy are each associated with greater diabetes self-efficacy, and greater diabetes self-efficacy is associated with lower A1C levels. Diabetes self-efficacy may be an important target of interventions to improve diabetes control and promote health equity related to health literacy and general numeracy skills needed for diabetes management.

Depression and low self-efficacy are both associated with worse glycemic control in adults with diabetes, but the relationship between these variables is poorly understood. We conducted a cross-sectional study examining associations between depressive symptoms, self-efficacy, and glycemic control among men ( n = 64) and women ( n = 98) with type 2 diabetes to see if self-efficacy mediates the relationship between depression and glycemic control. Correlational and mediational analyses examined the relationship between these three variables for the sample as a whole and separately by sex. A significant association between depressive symptoms and glycemic control was found for men (0.34, P < 0.01) but not for women (0.05, P = 0.59). Path analysis suggested that, among men, self-efficacy mediates the relationship between depressive symptoms and glycemic control. We conclude that men with depressive symptoms and type 2 diabetes may need tailored interventions that improve their self-efficacy in order to achieve glycemic control. [ABSTRACT FROM AUTHOR]

Objective: Diabetic patients with lower literacy or numeracy skills are at greater risk for poor diabetes outcomes. This study evaluated the impact of providing literacy- and numeracy-sensitive diabetes care within an enhanced diabetes care program on A1C and other diabetes outcomes.Research Design and Methods: In two randomized controlled trials, we enrolled 198 adult diabetic patients with most recent A1C >or=7.0%, referred for participation in an enhanced diabetes care program. For 3 months, control patients received care from existing enhanced diabetes care programs, whereas intervention patients received enhanced programs that also addressed literacy and numeracy at each institution. Intervention providers received health communication training and used the interactive Diabetes Literacy and Numeracy Education Toolkit with patients. A1C was measured at 3 and 6 months follow-up. Secondary outcomes included self-efficacy, self-management behaviors, and treatment satisfaction.Results: At 3 months, both intervention and control patients had significant improvements in A1C from baseline (intervention -1.50 [95% CI -1.80 to -1.02]; control -0.80 [-1.10 to -0.30]). In adjusted analysis, there was greater improvement in A1C in the intervention group than in the control group (P = 0.03). At 6 months, there were no differences in A1C between intervention and control groups. Self-efficacy improved from baseline for both groups. No significant differences were found for self-management behaviors or satisfaction.Conclusions: A literacy- and numeracy-focused diabetes care program modestly improved self-efficacy and glycemic control compared with standard enhanced diabetes care, but the difference attenuated after conclusion of the intervention.

Objective: Understanding the reasons and eliminating the pervasive health disparities in diabetes is a major research, clinical, and health policy goal. We examined whether health literacy, general numeracy, and diabetes-related numeracy explain the association between African American race and poor glycemic control (A1C) in patients with diabetes.Research Design and Methods: Adults with type 2 diabetes (n = 383) were enrolled in a cross-sectional study at primary care and diabetes clinics at three medical centers. Data collected included the following: self-reported race, health literacy, general numeracy, diabetes-related numeracy, A1C, and sociodemographic factors. A series of structural equation models were estimated to explore the interrelations between variables and test for mediation.Results: In model 1, younger age (r = -0.21, P < 0.001), insulin use (r = 0.27, P < 0.001), greater years with diabetes (r = 0.16, P < 0.01), and African American race (r = 0.12, P < 0.01) were all associated with poorer glycemic control. In model 2, diabetes-related numeracy emerged as a strong predictor of A1C (r = -0.46, P < 0.001), reducing the association between African American and poor glycemic control to nonsignificance (r = 0.10, NS). In model 3, African American race and older age were associated with lower diabetes-related numeracy; younger age, insulin use, more years with diabetes, and lower diabetes-related numeracy were associated with poor glycemic control.Conclusions: Diabetes-related numeracy reduced the explanatory power of African American race, such that low diabetes-related numeracy, not African American race, was significantly related to poor glycemic control. Interventions that address numeracy could help to reduce racial disparities in diabetes. [ABSTRACT FROM AUTHOR]

This study examined the relationship between spiritual well-being (SWB) and perceived control (PC) in adult patients with heart failure (HF). The sample included 75 adults ranging in age from 27 to 82 years. Participants verbally completed study questionnaires in a clinic room selected for privacy. Multiple linear regression results indicated that increased existential spiritual well-being (a subscale of SWB) predicted increased PC. Thus, patients with HF who adjust to personal changes and who also connect with others may develop meaning and purpose in life and may perceive increased control over their heart disease.

Aim. This paper is a report of a study examining the relationships among number of roles, role quality, role stress, role balance, and psychological well-being in women diagnosed with rheumatoid arthritis. Background. A substantial literature exists examining multiple roles in healthy women. However, less is known about multiple roles and well-being in women with a chronic illness such as rheumatoid arthritis. Methods. A questionnaire study was conducted in 2003 examining four role-related constructs (number of roles, quality of roles, role stress, and role balance) and psychological well-being in healthy women ( n = 47) and women diagnosed with rheumatoid arthritis ( n = 50). Correlation coefficients and multiple regression analyses were calculated to determine the nature of the relationships among the variables. Findings. The two groups were similar in demographics except for employment, with fewer women with rheumatoid arthritis employed. The two groups differed statistically significantly on psychological well-being. Women with rheumatoid arthritis had a lower mean psychological well-being score than healthy women. Regression analyses revealed that role stress was the only unique predictor of psychological well-being in healthy women, while role balance was the sole unique predictor among women with rheumatoid arthritis. Conclusion. Women with rheumatoid arthritis experienced lower levels of well-being than their healthy counterparts. Examination of the relationships among the variables can facilitate the development of interventions to improve these women's mental health. Nurses are in a position to assess the psychosocial needs of women with rheumatoid arthritis and assist those experiencing role stress and role imbalance. [ABSTRACT FROM AUTHOR]

Patients with chronic medical conditions such as diabetes mellitus need to self-manage their condition for optimal outcomes. The degree to which patients with diabetes feel competent or self-efficacious in managing their diabetes has been related to behaviors such as dieting or exercise as well as to indicators of glycemic control. A diabetes-specific adaptation of the Perceived Medical-Condition Self-Management Scale was administered to 398 patients with either type 1 (n=57) or type 2 (n=341) diabetes. Cronbach's alpha of the 8-item Perceived Diabetes Self-Management Scale (PDSMS) was .83 indicating internal consistency. PDSMS scores were uncorrelated with age, years since diagnosis, and years of schooling, but were negatively correlated with body mass index. Those with type 1 DM had higher PDSMS scores than those with type 2 DM. PDSMS scores were positively correlated with a number of self-reported self-care activities and negatively related to measures of glycemic control. The PDSMS is a valid measure of diabetes self-efficacy, and the more generic template from which it was adapted can easily be altered for use with other chronic medical conditions.

Background: Inadequate blood pressure control is a persistent gap in quality care.Objective: To evaluate provider and patient interventions to improve blood pressure control.Design: Cluster randomized, controlled trial.Setting: 2 hospital-based and 8 community-based clinics in the Veterans Affairs Tennessee Valley Healthcare System.Patients: 1341 veterans with essential hypertension cared for by 182 providers. Eligible patients had 2 or more blood pressure measurements greater than 140/90 mm Hg in a 6-month period and were taking a single antihypertensive agent.Intervention: Providers who cared for eligible patients were randomly assigned to receive an e-mail with a Web-based link to the Seventh Report of the Joint National Committee on the Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC 7) guidelines (provider education); provider education and a patient-specific hypertension computerized alert (provider education and alert); or provider education, hypertension alert, and patient education, in which patients were sent a letter advocating drug adherence, lifestyle modification, and conversations with providers (patient education).Measurements: Proportion of patients with a systolic blood pressure less than 140 mm Hg at 6 months; intensification of antihypertensive medication.Results: Mean baseline blood pressure was 157/83 mm Hg with no differences between groups (P = 0.105). Six-month follow-up data were available for 975 patients (73%). Patients of providers who were randomly assigned to the patient education group had better blood pressure control (138/75 mm Hg) than those in the provider education and alert or provider education alone groups (146/76 mm Hg and 145/78 mm Hg, respectively). More patients in the patient education group had a systolic blood pressure of 140 mm Hg or less compared with those in the provider education or provider education and alert groups (adjusted relative risk for the patient education group compared with the provider education alone group, 1.31 [95% CI, 1.06 to 1.62]; P = 0.012).Limitations: Follow-up blood pressure measurements were missing for 27% of study patients. The study could not detect a mechanism by which patient education improved blood pressure control.Conclusions: A multifactorial intervention including patient education improved blood pressure control compared with provider education alone.

There is evidence that an individual's health beliefs influence performance of health behaviors. The purpose of this study was to determine whether health beliefs in persons with diabetes could be modified during a clinical education program and whether the health beliefs were related to adherence to self-care instructions and metabolic control of diabetes. Health beliefs and HbA were measured at baseline in 189 adult outpatients with diabetes. Diabetes educators then attempted to modify health beliefs that were not conducive to positive health behaviors. Following education, some health beliefs were modified in a positive direction. Modest, but statistically significant increases in perceived severity of diabetes, perceived ability to carry out recommended behaviors, and perceived benefits of treatment were observed. Although HbA improved significantly in a subgroup of patients, this improvement could not be directly associated with any health belief or with self-reported adherence by the measures used in this study.

OBJECTIVE: The purpose of this study was to test the effectiveness of a cognitive-behavioral intervention program designed to affect perceptions of control and coping patterns in women with rheumatoid arthritis (RA). DESIGN: Quasi-experimental. SETTING: Not given. POPULATION: Ninety women with rheumatoid arthritis between the ages of 24 and 80 were recruited and enrolled in the program over an 18-month period. The average length of time since diagnosis with RA was 10.3 years. INTERVENTIONS: After meeting entry criteria and giving written informed consent, participants completed and mailed back a battery of self-report instruments 6 weeks prior to beginning the intervention, labeled Time 1. Participants also completed these same measures during the week prior to beginning the intervention, labeled Time 2, immediately after the intervention, labeled Time 3, and at a 3-month follow-up, labeled Time 4. The intervention program, called Rising Above Arthritis, was designed to help women with RA develop a sense of competence with respect to both arthritis-related problems and other life stressors. Participants watched a videotape and reviewed manual material prior to attending each of the three small-group sessions scheduled 2 weeks apart. A major theme of the intervention program is that individuals have some control over their responses to stressors, even if it is only attitudinal control. MAIN OUTCOME MEASURE(S): The measures were selected because of their conceptual congruency with this investigation and because their reliability and validity for this population have been well established. The Perceived Health Competence Scale is an eight-item measure of the extent to which individuals perceive control over their health status in general. The Arthritis Self-Efficacy Scales for pain were used to assess competency beliefs related to arthritis symptomatology. Other measures used included the five-item Helplessness subscale from the Arthritis Helplessness Index, a shortened version of the Vanderbilt Multidimensional Pain Coping Inventory, the five-item Satisfaction with Life Scale and the 2-item version of the Positive and Negative Affect Schedule (PANAS). RESULTS/CONCLUSIONS: The MANOVA results were significant, indicating that the set of personal coping resources changed significantly over time. All of the gains established during the course of the program were maintained over the subsequent 3 months. The answer to the first research question related to the impact of the program on disease symptomatology depends on which symptom is considered. The program had the greatest impact on personal coping resources such as self-efficacy for controlling arthritis symptomatology. The majority of the significant improvement in the MANOVA of disease symptomatology was due to the highly significant improvement in perceived fatigue. [CINAHL abstract] [ABSTRACT FROM AUTHOR]

CONTEXT: Because surgery, radiation, and/or chemotherapy disrupt lymphatic structures, damage soft tissue leading to scar tissue formation and fibrosis, and further affect lymphatic function, patients with head and neck cancer may be at high risk for developing secondary lymphedema. Yet, no published data are available regarding the prevalence of secondary lymphedema after head and neck cancer treatment. OBJECTIVES: The aim of this study was to examine prevalence of secondary lymphedema in patients with head and neck cancer. METHODS: The study included 81 patients with head and neck cancer who were three months or more post-treatment. External lymphedema was staged using Foldi's lymphedema scale. Internal lymphedema was identified through a flexible fiber-optic endoscopic or mirror examination. Patterson's scale was used to grade degrees of internal lymphedema. RESULTS: Of the 81 patients, 75.3% (61 of 81) had some form of late-effect lymphedema. Of those, 9.8% (6 of 61) only had external, 39.4% (24 of 61) only had internal, and 50.8% (31 of 61) had both types. CONCLUSION: Lymphedema is a common late effect in patients with head and neck cancer, and it develops in multiple external and internal anatomical locations. During physical examination and endoscopic procedures, clinicians should assess patients with head and neck cancer for late-effect lymphedema. Referral for treatment should be considered when lymphedema is noted. Research is needed to examine risk factors of lymphedema in patients with head and neck cancer and its effects on patients' symptoms, function, and quality of life.Copyright © 2012 by Elsevier Inc.

Background: Breast cancer is the most common tumor among women throughout the world. Diagnosis and treatment of breast cancer are associated with stress and depression. Self-efficacy is one of the most important personal characteristics, studied in cancer, and is correlated with depression and immunity. The aim of the study is as follows: 1. Examining the correlation between coping self-efficacy with depression, DHEA levels, and immunity 2. Examining the correlation between depression and DHEA levels 3. Studying the effect of depression and DHEA levels on immunity 4. Examining the intermediate effect of DHEA levels on the correlation between coping self-efficacy and immunity METHODS: Thirty newly diagnosed breast cancer patients recruited from the Oncology Department, Kasr EL-Aini, Cairo University (ages 51.40 + 8.24 years) responded to two questionnaires: Coping Self-Efficacy Scale (CSES) and Patient Health Questionnaire-9 (PHQ-9); blood samples were collected to measure the phenotype of patients' cellular immunity and DHEA levels by flowcytometry and ELISA technique., Results: There was a significant negative correlation between CSES and PHQ-9, a significant positive correlation between PHQ-9 and B-cell count, and there is a significant negative correlation between CSES and B-cell count. The presence of DHEA has no mediatory role on correlation between CSES and B-cell count., Conclusion: This paper presents a new model of psychoneuroimmunology by suggesting an effect of coping self-efficacy on immunity against breast cancer patients., (© 2023.

Purpose: Cardiac rehabilitation (CR), a program of supervised exercise and cardiovascular risk management, is widely underutilized. Psychological factors such as perceived health competence, or belief in one's ability to achieve health-related goals, may play a role in CR initiation. The aim of this study was to evaluate the association of perceived health competence with CR initiation among patients hospitalized for acute coronary syndrome (ACS) after adjusting for demographic, clinical, and psychosocial characteristics., Methods: The Vanderbilt Inpatient Cohort Study (VICS) characterized the effect of psychosocial characteristics on post-discharge outcomes in ACS inpatients hospitalized from 2011 to 2015. The primary outcome for this analysis was participation in an outpatient CR program. The primary predictor was the two-item Perceived Health Competence Scale (PHCS-2), which yields a score from 2 to 10 (higher scores indicate greater perceived health competence). Multiple logistic regression was used to evaluate the relationship between the PHCS-2 and CR initiation., Results: A total of 1809 VICS participants (median age: 61 yr, 39% female) with ACS were studied, of whom 294 (16%) initiated CR. The PHCS-2 was associated with a higher odds of CR initiation (OR = 1.15/point increase: 95% CI, 1.06-1.26, P = .001) after adjusting for covariates. Participants with comorbid heart failure had a lower odds of CR initiation (OR = 0.31: 95% CI, 0.16-0.60, P < .001) as did current smokers (OR = 0.64: 95% CI, 0.43-0.96, P = .030)., Conclusion: Perceived health competence is associated with outpatient CR initiation in patients hospitalized with ACS. Interventions designed to support perceived health competence may be useful for improving CR participation., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: Ethical issues in trauma surgery are commonplace but scarcely studied. We aim to characterize the ethical dilemmas trauma surgeons encounter in clinical practice and describe perceptions about the ability to manage these dilemmas and strategies they use to address them., Methods: Members of a U.S. trauma society were electronically surveyed on handling ethically challenging scenarios. The survey instrument was developed using published ethics literature and iterative cognitive interviews. Domains included perceived frequency of encountering and self-efficacy of managing ethical situations in trauma surgery. Common situations were defined as those encountered monthly or weekly. Ethical problems were categorized within 7 larger categories: general ethics, autonomy, communication, justice, end-of-life, conflict, and other. Descriptive analyses were performed; group comparisons were analyzed using analysis of variance., Results: Of 1,748 surveyed, 548 responded (30.6%) and 154 (28%) were female. Most were White, under 55 years age, had completed fellowship training, and were practicing at a level I or II trauma center. The most encountered ethical categories were generic ethics and communication (79%). Issues involving conflict were least frequent (21%). Respondents felt most uncomfortable with autonomy topics. Respondents with high self-efficacy in handling ethical situations were older, in practice ≥15 years, served on an ethics committee, and/or frequently experienced ethical challenges., Conclusion: Most trauma surgeons regularly encounter ethical challenges, especially those related to communication. Trauma surgeons encounter ethical issues involving conflict least often, and lowest self-efficacy scores with issues involving autonomy. Experienced trauma surgeons reported higher self-efficacy scores in managing ethical issues. Future work should examine how self-efficacy translates to observed behavior, and how trauma surgeons build and enhance their ethical skillsets in the care of the injured patient., (Published by Elsevier Inc.)

Background: My Diabetes Care (MDC) is a novel, multifaceted patient portal intervention designed to help patients better understand their diabetes health data and support self-management. MDC uses infographics to visualize and summarize patients' diabetes health data, incorporates motivational strategies, and provides literacy level-appropriate educational resources., Objectives: We aimed to assess the usability, acceptability, perceptions, and potential impact of MDC., Methods: We recruited 69 participants from four clinics affiliated with Vanderbilt University Medical Center. Participants were given 1 month of access to MDC and completed pre- and post-questionnaires including validated measures of usability and patient activation, and questions about user experience., Results: Sixty participants completed the study. Participants' mean age was 58, 55% were females, 68% were Caucasians, and 48% had limited health literacy (HL). Most participants (80%) visited MDC three or more times and 50% spent a total of ≥15 minutes on MDC. Participants' median System Usability Scale (SUS) score was 78.8 [Q1, Q3: 72.5, 87.5] and significantly greater than the threshold value of 68 indicative of "above average" usability ( p  < 0.001). The median SUS score of patients with limited HL was similar to those with adequate HL (77.5 [72.5, 85.0] vs. 82.5 [72.5, 92.5]; p  = 0.41). Participants most commonly reported the literacy level-appropriate educational links and health data infographics as features that helped them better understand their diabetes health data (65%). All participants (100%) intended to continue to use MDC. Median Patient Activation Measure® scores increased postintervention (64.3 [55.6, 72.5] vs. 67.8 [60.6, 75.0]; p  = 0.01)., Conclusion: Participants, including those with limited HL, rated the usability of MDC above average, anticipated continued use, and identified key features that improved their understanding of diabetes health data. Patient activation improved over the study period. Our findings suggest MDC may be a beneficial addition to existing patient portals., Competing Interests: None declared., (Thieme.

Background: Family and friends have both helpful and harmful effects on adults' diabetes self-management. Family-focused Add-on to Motivate Self-care (FAMS) is a mobile phone-delivered intervention designed to improve family/friend involvement, self-efficacy, and self-care via monthly phone coaching, texts tailored to goals, and the option to invite a support person to receive texts., Purpose: We sought to evaluate how FAMS was received by a diverse group of adults with Type 2 diabetes and if FAMS improved diabetes-specific family/friend involvement (increased helpful and reduced harmful), diabetes self-efficacy, and self-care (diet and physical activity). We also assessed if improvements in family/friend involvement mediated improvements in self-efficacy and self-care., Methods: Participants were prospectively assigned to enhanced treatment as usual (control), an individualized text messaging intervention alone, or the individualized text messaging intervention plus FAMS for 6 months. Participants completed surveys at baseline, 3 and 6 months, and postintervention interviews. Between-group and multiple mediator analyses followed intention-to-treat principles., Results: Retention, engagement, and fidelity were high. FAMS was well received and helped participants realize the value of involving family/friends in their care. Relative to control, FAMS participants had improved family/friend involvement, self-efficacy, and diet (but not physical activity) at 3 and 6 months (all ps < .05). Improvements in family/friend involvement mediated effects on self-efficacy and diet for FAMS participants but not for the individualized intervention group., Conclusions: The promise of effectively engaging patients' family and friends lies in sustained long-term behavior change. This work represents a first step toward this goal by demonstrating how content targeting helpful and harmful family/friend involvement can drive short-term effects., Trial Registration Number: NCT02481596., (© Society of Behavioral Medicine 2020.

Objective: To determine at which phase in the recruitment process for participation in clinical research studies do health literacy and other patient characteristics influence recruitment outcomes., Patients and Methods: Using a sample of 5872 patients hospitalized with cardiovascular disease approached for participation in the Vanderbilt Inpatient Cohort Study from October 2011 through December 2015, we examined the independent association of patients' health literacy with two steps in their research participation decision-making process: (1) research interest - willingness to hear more about a research study; and (2) research participation - the decision to enroll after an informed consent discussion. Best practices for effective health communication were implemented in recruitment approaches and informed consent processes. Using logistic regression models, we determined patient characteristics independently associated with patients' willingness to hear about and participate in the study., Results: In unadjusted analyses, participants with higher health literacy, and those who were younger, female, or had more education had higher levels of both research interest and research participation. Health literacy remained independently associated with both outcomes in multivariable models, after adjustment for sociodemographic factors., Conclusion: Because identical variables predicted both research interest and eventual consent, efforts to recruit broad populations must include acceptable methods of approaching potential participants as well as explaining study materials., (Copyright © 2020 Mayo Foundation for Medical Education and Research.

Context: Psychological distress is associated with adverse health outcomes in serious illness and magnified among patients of low socioeconomic status. Aspects of one's culture, such as religion and spirituality, can influence these patients' coping response to distress. Advanced chronic kidney disease (CKD) is a serious illness that disproportionately affects patients of low socioeconomic status, but a theory-based understanding of this group's lived experience of CKD is lacking., Objectives: We explored the cognitions, emotions, and coping behaviors of patients with CKD with emphasis on those of low socioeconomic status. We further inquired into any influences of religion or spirituality., Methods: We interviewed 50 English-speaking or Spanish-speaking adults with advanced CKD from three medical centers in Nashville, Tennessee. Analyses occurred with isolation of themes; development of a coding system; and creation of a conceptual framework using an inductive-deductive approach., Results: Median age was 65 years; median annual income was $17,500 per year; and 48% of participants had not progressed beyond high school. Key beliefs (awareness of mortality and lack of control) influenced patients' emotions (existential distress in the form of death anxiety, prognostic uncertainty, and hopelessness) and coping behaviors (acceptance, avoidance, emotion regulation via spirituality, and seeking socialsupport via a religious community)., Conclusion: Individuals with advanced CKD and low socioeconomic status lack control over disease progression, experience death anxiety and existential distress, and emphasize spirituality to cope. Our study identifies novel components for a psychotherapeutic intervention for patients with advanced CKD at high risk for adverse health outcomes., (Copyright © 2020 American Academy of Hospice and Palliative Medicine.

Objective: Text messaging interventions have high potential for scalability and for reductions in health disparities. However, more rigorous, long-term trials are needed. We examined the long-term efficacy and mechanisms of a tailored text messaging intervention., Research Design and Methods: Adults with type 2 diabetes participated in a parallel-groups, 15-month randomized controlled trial and were assigned to receive Rapid Education/Encouragement and Communications for Health (REACH) for 12 months or control. REACH included interactive texts and tailored texts addressing medication adherence and nontailored texts supporting other self-care behaviors. Outcomes included hemoglobin A 1c (HbA 1c ), diabetes medication adherence, self-care, and self-efficacy., Results: Participants ( N = 506) were approximately half racial/ethnic minorities, and half were underinsured, had annual household incomes <$35,000, and had a high school education or less; 11% were homeless. Average baseline HbA 1c was 8.6% ± 1.8%; 70.0 ± 19.7 mmol/mol) with n = 219 having HbA 1c ≥8.5% (69 mmol/mol). Half were prescribed insulin. Retention was over 90%. Median response rate to interactive texts was 91% (interquartile range 75%, 97%). The treatment effect on HbA 1c at 6 months (-0.31%; 95% CI -0.61%, -0.02%) was greater among those with baseline HbA 1c ≥8.5% (-0.74%; 95% CI -1.26%, -0.23%), and there was no evidence of effect modification by race/ethnicity or socioeconomic disadvantage. REACH improved medication adherence and diet through 12 months and self-efficacy through 6 months. Treatment effects were not significant for any outcome at 15 months. REACH reduced barriers to adherence, but barrier reduction did not mediate outcome improvements., Conclusions: REACH engaged at-risk patients in diabetes self-management and improved short-term HbA 1c . More than texts alone may be needed to sustain the effects., (© 2020 by the American Diabetes Association.)

Amid increasing interest in improving the patient-centeredness of research, new forms of engagement are emerging that enable researchers to get input from community members on research goals, methods, and implementation. This input often includes stories, which are useful for understanding lived experiences of illness and encounters with health care organizations, and for locating these experiences within larger meta-narratives of specific communities. We analyzed the stories in transcripts of 13 Community Engagement Studios and identified 4 major functions that the stories served in the sessions. Major functions included: (1) establishing mutual understanding, (2) adding expansion and depth, (3) characterizing abstract concepts, and (4) providing context for experience, with the latter being the most frequent. We assert that stories can serve to better communicate the complex contexts of patient experiences, helping to align research priorities and research design with community interests, leading to more patient-centered innovations in clinical practice., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2020.)

This cross-sectional study of 56 dialysis providers from 3 dialysis clinics examined providers' attitudes and perception of autonomy support for patients' medication adherence behaviors. Respondents completed surveys assessing attitudes and perception of autonomy support. Compared to all other provider types, physicians and nurse practitioners (MD/NP) thought it was "less true" that phosphate binder medications are very important for dialysis patients (MD/NP vs others: 5.1 [1.4] vs 6.1 [1.1]; P = 0.02). More dialysis technicians (19%) offered the highest level of support. Attitudes and perception of autonomy support for medication adherence are suboptimal, vary by dialysis provider type, and are targets for quality improvement in dialysis care. This study addresses critical gap in existing knowledge about these two novel provider-based psychosocial factors and their potential impact on phosphate binder medication adherence., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2019.)

This study aimed to develop a self-efficacy measure for mindfulness meditation practice (Self-efficacy for Mindfulness Meditation Practice scale). The scale was developed through a process of expert consensus, cognitive interviewing, and evaluation among 199 mindfulness meditation practitioners who completed an online survey. The 9-item Self-efficacy for Mindfulness Meditation Practice scale was unidimensional with three subconstructs of attention, compassion, and emotion. The omega hierarchical coefficient for the total scale was 0.78, and test-retest reliability was intraclass correlation coefficient = 0.85 (95% confidence interval: 0.80, 0.89). This study provides preliminary evidence that Self-Efficacy for Mindfulness Meditation Practice scale is a reliable and valid measure of self-efficacy for mindfulness meditation practice.

Background: The ability to understand another's emotions and act appropriately, empathy, is an important mediator of relationship function and health intervention fidelity. We adapted the Interpersonal Reactivity Index (IRI) - an empathy scale - among seroconcordant expectant couples with HIV in the Homens para Saúde Mais (HoPS+) trial - a cluster randomized controlled trial assessing couple-based versus individual treatment on viral suppression - in Zambézia Province, Mozambique., Methods: Using baseline data from 1332 HoPS+ trial participants (666 couples), an exploratory factor analysis assessed culturally relevant questions from the IRI. Because empathy is interdependent among couples, we validated the results of the exploratory factor analysis using a dyadic confirmatory factor analysis (CFA) with dyadic measurement invariance testing. Finally, we assessed the relationship between scores on our final scale and basic demographic characteristics (sex, age, education, and depression) using t-tests., Results: We found two subscales: 1) a seven-item cognitive empathy subscale (Cronbach's alpha 0.78) and 2) a six-item affective empathy subscale (Cronbach's alpha 0.73). The dyadic CFA found acceptable model fit and metric invariance across partners (Comparative Fit Index (CFI) = 0.914, Tucker Lewis Index = 0.904, Root Mean Squared Error of Approximation = 0.056, ΔCFI = 0.011). We observed higher cognitive (p: 0.012) and affective (p: 0.049) empathy among males and higher cognitive (p: 0.031) and affective (p: 0.030) empathy among younger participants. More educated participants had higher affective empathy (p: 0.017) and depressed participants had higher cognitive empathy (p: < 0.001). This two-subscale, 13-item version of the IRI measures cognitive and affective empathy in HoPS+ trial participants and adults while accounting for the interdependent nature of empathy within partner dyads., Conclusions: This scale will allow us to assess the interplay between empathy and other psychometric constructs (stigma, social support, etc.) in the HoPS+ trial and how each relates to retention in HIV, adherence to treatment, and prevention of maternal to child HIV transmission. Furthermore, this scale can be adapted for other sub-Saharan African populations, which will allow researchers to better assess HIV-related intervention efficacy., Trial Registration: This study is within the context of the HoPS+ trial, registered at ClinicalTrials.gov as number NCT03149237 . Registered May 11, 2017.

Introduction: Educational materials used in prostate cancer shared decision-making are often written above the health literacy levels of the patients that may benefit the most from such tools. Poor understanding the oncologic and functional outcomes of prostate cancer treatment may influence patient regret during this process. In this study, we assess the association between health literacy, numeracy, prostate-related knowledge and treatment regret in a diverse population., Materials and Methods: Patients obtaining care between June and August of 2016 at both community-based and academic tertiary care facilities were assessed for health literacy and numeracy using validated instruments. Prostate knowledge was tested in those patients without a history of prostate cancer using a 29-item questionnaire and patient-level predictors of knowledge were assessed. Prostate cancer treatment regret was assessed in those patients who had a history of prostate cancer., Results: A total of 90 patients were enrolled, 38 (42%) of whom had a history of prostate cancer. African American race (I = 0.039), financial strain (P < 0.001), and educational attainment (P < 0.001) were all associated with lower health literacy on multivariable analysis. Possessing a professional degree (P = 0.021) and higher health literacy (P = 0.001) were associated with greater prostate-related knowledge. Of those with a history of prostate cancer, 9 (24%) expressed treatment regret. Patients with regret were more likely to be African American (n = 6, 66.7% vs. 5, 17.2%, P = 0.004), not married (P = 0.016), and score lower on the literacy (1.0 vs. 8.0, P = 0.009) and numeracy (10.0 vs. 16.0, P = 0.016) scales., Conclusions: We identified lower health literacy among African American men, and lower prostate-related knowledge in those with poor health literacy. To our knowledge, this is the first study to show an association between health literacy and prostate cancer treatment regret., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: Text message-delivered interventions are a feasible and scalable approach for improving chronic disease self-care and reducing health disparities; however, information on long-term user engagement with these interventions is limited., Objective: The aim of this study is to examine user engagement in a 12-month text message-delivered intervention supporting diabetes self-care, called REACH (Rapid Education/Encouragement And Communications for Health), among racially and socioeconomically diverse patients with type 2 diabetes (T2D). We explored time trends in engagement, associations between patient characteristics and engagement, and whether the addition of a human component or allowing patients to change their text frequency affected engagement. Qualitative data informed patients' subjective experience of their engagement., Methods: We recruited patients with T2D for a randomized trial evaluating mobile phone support relative to enhanced treatment as usual. This analysis was limited to participants assigned to the intervention. Participants completed a survey and hemoglobin A1c (HbA1c) test and received REACH text messages, including self-care promotion texts, interactive texts asking about medication adherence, and adherence feedback texts. For the first 6 months, texts were sent daily, and half of the participants also received monthly phone coaching. After 6 months, coaching stopped, and participants had the option to receive fewer texts for the subsequent 6 months. We defined engagement via responses to the interactive texts and responses to a follow-up interview. We used regression models to analyze associations with response rate and thematic and structural analysis to understand participants' reasons for responding to the texts and their preferred text frequency., Results: The participants were, on average, aged 55.8 (SD 9.8) years, 55.2% (137/248) female, and 52.0% (129/248) non-White; 40.7% (101/248) had ≤ a high school education, and 40.7% (101/248) had an annual household income

Background: Effective type 2 diabetes care remains a challenge for patients including those receiving primary care in safety net settings., Objective: The Partnership to Improve Diabetes Education (PRIDE) trial team and leaders from a regional department of health evaluated approaches to improve care for vulnerable patients., Design: Cluster randomized controlled trial., Patients: Adults with uncontrolled type 2 diabetes seeking care across 10 unblinded, randomly assigned safety net clinics in Middle TN., Interventions: A literacy-sensitive, provider-focused, health communication intervention (PRIDE; 5 clinics) vs. standard diabetes education (5 clinics)., Main Measures: Participant-level primary outcome was glycemic control [A1c] at 12 months. Secondary outcomes included select health behaviors and psychosocial aspects of care at 12 and 24 months. Adjusted mixed effects regression models were used to examine the comparative effectiveness of each approach to care., Key Results: Of 410 patients enrolled, 364 (89%) were included in analyses. Median age was 51 years; Black and Hispanic patients represented 18% and 25%; 96% were uninsured, and 82% had low annual income level (< $20,000); adequate health literacy was seen in 83%, but numeracy deficits were common. At 12 months, significant within-group treatment effects occurred from baseline for both PRIDE and control sites: adjusted A1c (- 0.76 [95% CI, - 1.08 to - 0.44]; P < .001 vs - 0.54 [95% CI, - 0.86 to - 0.21]; P = .001), odds of poor eating (0.53 [95% CI, 0.33-0.83]; P = .01 vs 0.42 [95% CI, 0.26-0.68]; P < .001), treatment satisfaction (3.93 [95% CI, 2.48-6.21]; P < .001 vs 3.04 [95% CI, 1.93-4.77]; P < .001), and self-efficacy (2.97 [95% CI, 1.89-4.67]; P < .001 vs 1.81 [95% CI, 1.1-2.84]; P = .01). No significant difference was observed between study arms in adjusted analyses., Conclusions: Both interventions improved the participant's A1c and behavioral outcomes. PRIDE was not more effective than standard education. Further research may elucidate the added value of a focused health communication program in this setting.

Background: Religiosity, encompassing spirituality and religious practices, is associated with reduced disease incidence among individuals of low socioeconomic status and who self-identify as Black. We hypothesized that religiosity associates with reduced end-stage kidney disease (ESKD) risk among Black but not White adults of low socioeconomic status., Design: Cox models of religiosity and ESKD risk in 76,443 adults., Results: Black adults reporting high spirituality had reduced ESKD risk after adjusting for demographic characteristics [Hazard Ratio (HR) .82 (95% Confidence Interval (CI)) (.69-.98)], depressive symptoms, social support, and tobacco use [HR .81 (CI .68-.96)]. When clinical covariates were added, associations between spirituality and ESKD were slightly attenuated and lost significance [HR .85 (CI .68-1.06)]. Associations were not demonstrated among White adults., Conclusions: Spirituality associates with reduced ESKD risk among Black adults of low socioeconomic status independent of demographic, psychosocial, and behavioral characteristics. Effect modification by race was not statistically significant.

Background: Recent studies indicate the immune dysfunction in cancer patients in comparison with healthy individuals. The quality and quantity of this dysfunction are not equal in all patients even with similar cancer type., Aim: This study aims to correlate health locus of control (HLC) beliefs with CD4+ helper T (Thelper) cells, T regulatory (Treg) cells, NK cells, IL-1ß and TNF-a in breast cancer patients., Patients and Methods: The study included 30 early diagnostic breast cancer patients who responded to Form C of the MHLC questionnaire that assessed internal (IHLC), chance (CHLC), doctor (DHLC) and other person's (OHLC) control of the patient's health status. Peripheral blood samples were collected to analyze the numbers and phenotype of Thelper cells, Treg cells and NK cells by flow cytometry and to measure gene expression of IL-1ß and TNF-a with real time PCR., Results: A significant positive correlation was found between IHLC with Thelper cells and NK cells. However, a significant inverse correlation was found between DHLC with NK, Thelper and Treg cells., Conclusion: There is strong probability that the quality of immunity in cancer patients is related to their MHLC beliefs. Further research is recommended for studying whether MHLC beliefs of patients with other types of cancer can improve their immune responses and how beliefs control immune system.

Purpose: The purpose of this study was to evaluate the effect of evidence-based practice (EBP) courses on nursing students' attitudes, perceived support from their professional network, self-efficacy, knowledge, and implementation of EBP., Design: This study utilized a two-group, pre- and posttest design with 190 Masters of Science in Nursing (MSN) and 37 Doctorate of Nursing Practice (DNP) students., Methods: An EBP instrument based on the theory of planned behavior was administered both before and after the EBP course (the intervention)., Findings: Both the pre- and posttest were completed by 126 students for a 56% response rate. No significant differences between the MSN (n = 102) and DNP (n = 24) students were found in precourse scores on any of the subscales except behavior, with the DNP students reporting they performed more EBP behaviors in the clinical setting. Overall, student scores on three of the four subscales of the EBP instrument (attitudes, self-efficacy, and behavior) significantly increased pre- to postcourse. The self-efficacy subscale demonstrated the greatest pre- to postcourse change scores. When the DNP and MSN students were compared, change scores on attitudes and self-efficacy remained significant in both groups. There was a significant positive change in EBP behavior only for the MSN students. Knowledge scores increased significantly only for the DNP students., Linking Evidence to Action: EBP courses can increase self-reported EBP behaviors in the clinical setting, especially in MSN students. A precourse student evaluation will help faculty determine their learning needs in order to develop appropriate learning activities to support their acquisition of the essential knowledge, skills, and abilities to use EBP in the clinical setting. Administering the same evaluation postcourse can help faculty evaluate the effectiveness of their teaching. As a result, advanced practice nurses will be better equipped to facilitate and promote the implementation of EBP to support high-quality care and improved health outcomes., (© 2019 Sigma Theta Tau International.)

Background and Purpose: Examine the psychometric properties and factor structure of the Negative Behaviors in Healthcare (NBHC) Survey., Methods: A principal axis factor analysis with varimax rotation was conducted utilizing the 2012 NBHC survey data ( n = 1,918) to explore the underlying structure of the NBHC instrument. A confirmatory factor analysis using AMOS 23 (Arbuckle, 2014) was then conducted using the 2014 NBHC survey data ( n = 1,479)., Results: Internal consistency reliability was supported for four of the five identified factors, while construct validity for a five factor solution was established with acceptable model fit indices (Goodness of Fit Index [GFI] = 0.98; Relative Fit Index [RFI] = 0.98, Normed Fit Index [NFI] = 0.98, Root Mean Square Residual [RMR] = 0.05)., Conclusions: The NBHC instrument is a valid reliable instrument to assess negative behaviors among interprofessional healthcare team members, adding to a select few available instruments measuring negative behavior among interprofessional healthcare workers., (© Copyright 2019 Springer Publishing Company, LLC.)

The desire for control of healthcare is a significant moderator of outcomes related to childbirth. Researchers have shown that a sense of control of healthcare during childbirth is strongly correlated with postpartum maternal well-being. The aims of this study were to examine (a) the psychometric characteristics of an instrument to assess women's desire for control of healthcare during childbirth, and (b) examine desire for control in relation to parity, medical complications of pregnancy, and women's choices of childbirth providers and setting. The study design was cross-sectional using two different samples totaling 385 pregnant women. In Sample 1, (n = 193) we conducted an exploratory factor analysis to reduce the initial item pool. In Sample 2, (n = 192) we conducted a confirmatory factor analysis (CFA) of the final 12-item instrument and examined factors related to the desire for control. Results of the analysis in Sample 1 were supportive of a single-factor structure reflecting women's desire to influence the childbirth healthcare environment and decision-making. The final 12-item instrument had high internal consistency reliability (Cronbach's alpha = 0.93). CFA in Sample 2 was supportive of the single-factor structure with good model fit. The desire for control was directly correlated with an internal locus of control. Nulliparous women reported a lower desire for control compared with multiparous women. The desire for control among women with self-reported medical complications of pregnancy was comparable to that among women without pregnancy complications. The desire for control was a predictor of choosing midwives (vs. obstetricians), home or birth center (vs. hospitals), and professional labor support (e.g., doulas). Implications for future research on the impact of desire for control on maternal health outcomes are discussed., (© 2019 Wiley Periodicals, Inc.)

Background: The All of Us Research Program is building a national longitudinal cohort and collecting data from multiple information sources (e.g., biospecimens, electronic health records, and mobile/wearable technologies) to advance precision medicine. Participant-provided information, collected via surveys, will complement and augment these information sources. We report the process used to develop and refine the initial three surveys for this program., Methods: The All of Us survey development process included: (1) prioritization of domains for scientific needs, (2) examination of existing validated instruments, (3) content creation, (4) evaluation and refinement via cognitive interviews and online testing, (5) content review by key stakeholders, and (6) launch in the All of Us electronic participant portal. All content was translated into Spanish., Results: We conducted cognitive interviews in English and Spanish with 169 participants, and 573 individuals completed online testing. Feedback led to over 40 item content changes. Lessons learned included: (1) validated survey instruments performed well in diverse populations reflective of All of Us; (2) parallel evaluation of multiple languages can ensure optimal survey deployment; (3) recruitment challenges in diverse populations required multiple strategies; and (4) key stakeholders improved integration of surveys into larger Program context., Conclusions: This efficient, iterative process led to successful testing, refinement, and launch of three All of Us surveys. Reuse of All of Us surveys, available at http://researchallofus.org, may facilitate large consortia targeting diverse populations in English and Spanish to capture participant-provided information to supplement other data, such as genetic, physical measurements, or data from electronic health records.

Background: Identifying potential mechanisms that link depressed mood with worse health behaviors is important given the prevalence of depressed mood in patients with coronary heart disease (CHD) and its relationship with subsequent mortality. Perceived health competence is an individual's confidence in his/her ability to successfully engineer solutions to achieve health goals and may explain how depressed mood affects multiple health behaviors., Objective: Examine whether or not perceived health competence mediates the relationship between depressed mood and worse health behaviors., Design: A cross-sectional study conducted by the Patient-Centered Outcomes Research Institute-funded Mid-South Clinical Data Research Network between August 2014 and September 2015. Bootstrapped mediation was used., Participants: Patients with coronary heart disease (n = 2334)., Main Measures: Two items assessing perceived health competence, a single item assessing depressed mood, and a Health Behaviors Index including: the International Physical Activity Questionnaire (IPAQ); select items from the National Adult Tobacco Survey and the Alcohol Use Disorder Inventory Test; and single items assessing diet and medication adherence., Key Results: Depressed mood was associated with lower perceived health competence (a = - 0.21, p < .001) and lower perceived health competence was associated with worse performance on a Health Behaviors Index(b = 0.18, p < .001). Perceived health competence mediated the influence of depressed mood on health behaviors (ab = - 0.04, 95% CI = - 0.05 to - 0.03). The ratio of the indirect effect to the total effect was used as a measure of effect size (P M  = 0.26, 95% CI: 0.18 to 0.39)., Conclusions: Depressed mood is associated with worse health behaviors directly and indirectly via lower perceived health competence. Interventions to increase perceived health competence may lessen the deleterious impact of depressed mood on health behaviors and cardiovascular outcomes.

Introduction: Among patients with type 2 diabetes, racial disparities are prevalent across a variety of outcomes; however, inconsistent disparities in determinants of outcomes warrants exploring the impact of other, related factors. This study sought to examine whether disparities in health literacy, numeracy, self-care behaviors, and HbA1c persisted between non-Hispanic blacks and non-Hispanic whites after applying a robust adjustment for socioeconomic status (SES)., Methods: From 2016 to 2018, adult patients with type 2 diabetes (N=444) were recruited from primary care clinics. Participants self-reported demographics; indicators of SES (i.e., income, education, health insurance, housing status, and financial strain); subjective health literacy and numeracy; and self-care behaviors. Participants also completed an HbA1c test. In 2018, differences were examined between non-Hispanic blacks and non-Hispanic whites in health literacy, numeracy, self-care, and HbA1c, first unadjusted and then adjusted using propensity score weighting., Results: In unadjusted analyses, compared with non-Hispanic whites, non-Hispanic blacks had lower health literacy (p=0.039) and numeracy (p<0.001); less medication adherence (p=0.009); use of information for dietary decisions (p=0.013); and problem eating behaviors (p<0.001; i.e., non-Hispanic blacks reported fewer problems); and higher HbA1c levels (p=0.005). After adjusting for all SES indicators, only the reverse disparity in problem eating behaviors (p=0.016) and the disparity in HbA1c (p=0.011) remained., Conclusions: Findings highlight the importance of considering SES when examining disparities in health-related skills and behaviors. Moving beyond education and income to inclusion of more comprehensive markers of SES can improve understanding of how SES may contribute to disparities and the ability to appropriately target factors leading to inequality., (Copyright © 2019 American Journal of Preventive Medicine.

Objective: Develop and evaluate a measure assessing helpful and harmful family/friends' involvement in adults' type 2 diabetes (T2D) self-management., Methods: Prior mixed-methods research, cognitive interviews, and expert input informed measure development. We administered the measure in two studies (N = 392 and N = 512) to evaluate its factor structure, internal consistency reliability, test-retest reliability, and construct, criterion and predictive validity., Results: Analyses supported a two-factor solution: helpful and harmful involvement with internal consistency reliability α = .86 and .72, respectively. Three-month test-retest reliability was rho = 0.64 for helpful and rho = 0.61 for harmful (both p < 0.001). Over 90% reported at least one instance of family/friend involvement in the past month. Associations with other measures of diabetes involvement were as anticipated (all p < .01). Helpful and harmful involvement were independently associated with diabetes self-efficacy, diet, blood glucose testing and medication adherence cross-sectionally [βs 0.13-0.39 helpful, -0.12--0.33 harmful; all p < .05]. Harmful involvement independently predicted worse HbA1c (β = 0.08), and worsening HbA1c over three months (β = 0.12, both p < 0.05)., Conclusion: The Family and Friend Involvement in Adults' Diabetes (FIAD) is a reliable and valid measure assessing family/friend involvement in adults' T2D., Practice Implications: FIAD use can inform interventions to improve social contexts in which adults manage diabetes., (Copyright © 2019 Elsevier B.V.

Objective: Lack of trust toward medical research is a major barrier to research participation, particularly among some population groups. Valid measures of trust are needed to develop appropriate interventions. The study purpose was to compare two previously validated scales that measure trust in biomedical research - one developed by Hall et al. (H-TBR; 2006) and the other by Mainous et al. (M-TBR; 2006) - in relation to socio-demographic variables and attitudes toward research. Differences between Black and White respondents were explored., Methods: Two nearly identical surveys - one with H-TBR and the other with M-TBR - were systematically administered to a convenience sample. Internal consistency reliability of each scale was assessed. Associations were computed between scores on each scale with attitudes toward biomedical research and demographic variables (i.e., gender, age, race, and socioeconomic status). The difference between White and Black respondents on each TBR score while controlling for age, education, and race was also investigated., Results: A total of 2020 participants completed the H-TBR survey; 1957 completed the M-TBR survey. Mean item scores for M-TBR were higher ( F = 56.05, p < 0.001) among Whites than Blacks. Whites also had higher mean item scores than Blacks on H-TBR ( F = 7.09, p < 0.001). Both scales showed a strong association with participants' perceived barriers to research (ps < 0.001) and significant, positive correlations with interest in research participation (ps < 0.001). Age and household income were positive predictors of TBR scores, but the effects of education differed., Conclusions: Both scales are internally consistent and show associations with attitudes toward research. Whites score higher than Blacks on both TBR scales, even while controlling for age and socioeconomic status., (© The Association for Clinical and Translational Science 2019.)
