Prospective evaluation of the effects of stress on exercise adherence in community-residing women.

The effects of stress on exercise behavior in community-residing women exercising on their own were assessed. Participants (N = 82) completed a background questionnaire and kept exercise diaries and Weekly Stress Inventories (P. J. Brantley, G. N. Jones, E. Boudreax, & S. L. Catz, 1997) for 8 consecutive weeks. During weeks with a high frequency of stressful events, participants exercised for less time and reported lower self-efficacy for meeting upcoming exercise goals. During weeks of high perceived stress, participants exercised significantly fewer days, omitted more planned exercise sessions, were less satisfied with their exercise, and had lower self-efficacy for meeting exercise goals. Findings suggest that perceptions of stressful events and cognitive reactions to missed exercise may play a significant role in mediating exercise behavior and support the view of exercise relapse as an ongoing process.

Assessing the Value of the Diabetes Educator

Purpose The purpose of this study was to evaluate the effectiveness of diabetes self-management education or training provided by diabetes educators in reducing complications and improving quality of life. Methods Commercial and Medicare payer-derived claims data were used to assess the relationship between DSME/T and cost. Unlike the prior study that examined diabetes education provided by all professionals, the current study focused on the value of interventions performed as part of formal accredited/recognized diabetes education programs provided by diabetes educators only. Specifically, the current study focused on diabetes education delivered in diabetes self-management training programs based on 2 codes (G0108 and G0109). Results Results of the study provide insights into the differences in trends between participants and nonparticipants in DSMT. People with diabetes who had DSMT encounters provided by diabetes educators in accredited/recognized programs are likely to show lower cost patterns when compared with a control group of people with diabetes without DSMT encounters. People with diabetes who have multiple episodes of DSMT are more likely to receive care in accordance with recommended guidelines and to comply with diabetes-related prescription regimens, resulting in lower costs and utilization trends. Conclusions and Policy Implications The collaboration between diabetes educators and patients continues to demonstrate positive clinical quality outcomes and cost savings. This analysis shows that repeated DSMT encounters over time result in a dose-response effect on positive outcomes.

Mindfulness and acceptance are associated with exercise maintenance in YMCA exercisers

Although most U.S. adults have initiated an exercise program at some time, only a fraction are able to maintain consistent exercise. Instead, research suggests that intermittent exercise is commonplace among U.S. adults, underscoring the importance of identifying factors associated with consistent exercise at a level that promotes health and long-term maintenance of this activity. We proposed a theoretical model in which mindfulness and acceptance may promote exercise initiation and maintenance. Mindfulness, acceptance, and suppression were examined as a function of exercise status in 266 YMCA exercisers. Those who were successful at maintaining exercise tended to score higher on measures of mindfulness and acceptance, and lower on measures of suppression. Findings are discussed in light of our proposed theoretical model in which exercisers having greater mindfulness and acceptance are less reactive; responding with more balanced appraisals to threats to their exercise regimen which in turn promotes increased exercise maintenance. Future studies should utilize longitudinal design to examine causal relationships between variables.

Development and validation of The Personal Diabetes Questionnaire (PDQ): A measure of diabetes self-care behaviors, perceptions and barriers

AIM To develop and evaluate the validity and reliability of The Personal Diabetes Questionnaire (PDQ), a brief, yet comprehensive measure of diabetes self-care behaviors, perceptions and barriers. To examine individual items to provide descriptive and normative information and provide data on scale reliability and associations between PDQ scales and concurrently assessed HBA(1c) and BMI. METHOD Items were written to address nutritional management, medication utilization, blood glucose monitoring, and physical activity. The initial instrument was reviewed by multidisciplinary diabetes care providers and items subsequently revised until the measure provided complete coverage of the diabetes care domains using as few items as possible. The scoring scheme was generated rationally. Subjects were 790 adults (205 with type 1 and 585 with type 2 diabetes) who completed the PDQ while waiting for clinic appointments. RESULTS Item completion rates were high, with few items skipped by participants. Subscales demonstrated good internal consistency (Cronbach α=.650-.834) and demonstrated significant associations with BMI (p ≤.001) and HbA(1c) (p ≤.001). CONCLUSIONS The PDQ is a useful measure of diabetes self-care behaviors and related perceptions and barriers that is reliable and valid and feasible to administer in a clinic setting. This measure may be used to obtain data for assessing diabetes self-management and barriers and to guide patient care.

An environmental intervention aimed at increasing physical activity levels in low-income women.

Background: Regular physical activity is a health promotion and disease prevention behavior. Of all demographic groups, low-income women report the lowest levels of physical activity. Research Objective: The purpose of this study was to test an intervention aimed at reducing community environmental barriers to physical activity in low-income women. Methods: The research design was mixed methodology: (1) quantitative (quasi-experimental, pretest-posttest, cohort design in which no treatment partitioning was possible) and (2) qualitative (focus groups). The setting was a church-sponsored community center centrally located in a low-income urban neighborhood. The comparison group was recruited first followed by the intervention group to control for setting. The sample consisted of 104 women (comparison group, n = 53; intervention group, n = 51) between the ages of 18 and 63 years who were residents of neighborhoods served by the community center. Results: No between-group differences were found for physical activity behavior. Significant between-group differences in cholesterol (P = .007) and perception of physical activity (P = .033) were observed. Significant intervention group increases from pretest to posttest were found related to advanced registered nurse practitioner support, friend support, and more positive physical activity environment at the community center. Qualitative data supported and enriched the quantitative data. Conclusions: Physical activity levels were not significantly different between the groups. In a sample of low-income women who have multiple barriers, improving attitudes, expanding their knowledge of community resources, and providing physical activity opportunities in their neighborhoods are important intermediate steps toward initiation and maintenance of regular physical activity.

Monitoring in Diabetes Self-Management: Issues and Recommendations for Improvement

The American Association of Diabetes Educators hosted a Monitoring Symposium during which 18 invited participants considered pre-set questions regarding how diabetes education can more effectively address barriers to monitoring for people with diabetes and related conditions. This report provides a summary of the moderated discussion and highlights the key points that apply to diabetes educators and other providers involved with diabetes care. The participating thought leaders reviewed findings from published literature and participated in a moderated discussion with the aim of providing practical advice for health care practitioners regarding monitoring for people with diabetes so that the overall health of this population can be enhanced. The discussants also defined monitoring for diabetes as including that done by the clinician or laboratory, as well as self-monitoring. The discussion was distilled into key points that apply to diabetes educators and other providers involved with diabetes care. Participants developed specific recommendations for a self-monitoring behavior and monitoring framework. People with diabetes benefit from instruction and guidance about self-monitoring and decision making that is based on monitored results and informed interactions with providers. Importantly, collaboration among the entire diabetes care community is needed to ensure that monitoring is performed and utilized to its fullest advantage. Going forward, it will be critical to mitigate barriers to diabetes self-management and training and to identify linkages and partnerships to address barriers to self-monitoring.

Understanding systems and rhythms for minority recruitment in intervention research.

We describe one approach for recruitment and retention of minority individuals in intervention research using a systematic environmental perspective based on Bronfenbrenners ecological systems (BES) model and the construct of temporality. An exemplar in a physical activity intervention study with low-income and primarily African American women is presented. The exemplar illustrates application of BES and temporality to enhance recruitment and retention in research focused on understanding and accommodating environmental influences. Using this theory based approach resulted in successful recruitment and a high level of participant retention.

Development and Evaluation of a Nutrition and Physical Activity Counseling Module for First-Year Medical Students

Abstract: Introduction: Few Americans follow recommendations regarding nutrition or physical activity, and few physicians provide nutritional counseling (NC) or physical activity counseling (PAC) to patients. Clinical, systems-based, and institutional barriers to teaching and providing NC and PAC exist, but theoretical models of behavior change and principles of adult learning theory (ALT) can enable medical educators to overcome these barriers. Methods: We developed an educational intervention consisting of interactive lectures and two standardized patient experiences to provide first-year medical students with practical experience in PAC and NC. Students completed pre and post educational assessments of attitudes, knowledge, and self-efficacy with the counseling techniques. Results: Knowledge scores increased from 6.1 to 8.5 (p<.001) on a 13-item test. Self-confidence scores for NC increased from 45 to 78 (p<.001), and self-confidence scores for PAC increased from 51 to 82 (p<.001). While overall attitudes regarding the necessity and utility of counseling with specific disease states were not different pre/ post test (necessity pre/post 6.3 to 6.2 p= .71; utility pre/post 5.8 to 5.7 p=.88), necessity and utility scores for disease states treated primarily with counseling were different compared to disease states students perceive to be primarily pharmacologically treated (counseling vs. pharmacological necessity 5.9 vs. 6.6 p<.001; utility 5.4 vs. 6.1 p<.001). Conclusion: An educational intervention based on theoretical models of behavior change and ALT can increase knowledge and self confidence scores regarding counseling for NC and PAC.

Depression may mediate the relationship between sense of coherence and quality of life in lung cancer patients.

Lung cancer patients generally experience high levels of physical and psychological distress and decreased quality of life (QOL). Sense of coherence (SOC) has been conceptualized as a personality orientation reflecting the degree to which an individual perceives their world as comprehensible, manageable and meaningful. The present study investigated the associations of SOC with QOL in lung cancer. It also examined potential psychological mediators by which SOC may exert its influences on QOL. Fifty-six participants with non-small cell lung cancer were administered self-report assessments of SOC, QOL and psychological distress. Results revealed that SOC was positively associated with QOL and this relationship may be mediated by depressive symptoms. The current study supports the notion that SOC may be a protective factor with regard to psychological adjustment and QOL in cancer survivors.

Diet self-management and readiness to change in underserved adults with type 2 diabetes.

AIM Dietary assessment in diabetes may be enhanced by considering patient-centered perspectives and barriers to change within IDF guidelines. Consideration of readiness to change (RTC) diet in underserved samples may guide future interventions in high risk populations. This study assesses the utility of a rapid assessment of RTC diet in a medically underserved sample. METHOD Participants were 253 Black (43.7%) and White (55.1%) American adults with type 2 diabetes [M age=57.93 (11.52); 60.5% female; 19% below the US poverty threshold]. Participants were recruited at medical clinics and completed validated self-report measures assessing diabetes knowledge, self-efficacy and dietary behaviors and barriers by RTC. RESULTS Stage-based comparisons identified significant differences in diabetes and dietary domains: participants in the Action stage endorsed fewer behavioral dietary barriers (p<.001), more frequent dietary problem-solving (p<.001), and greater diabetes self-efficacy (p<.001) than participants in the Contemplation and Preparation stages. Women were more likely to be in the Preparation stage and beyond (p<.05). CONCLUSIONS Findings highlight the clinical utility of a brief measure of RTC in understanding patient perspectives toward dietary behaviors in a medically underserved sample. The impact of gender on RTC diet warrants further exploration.
