Lifestyle Health-Related Self-Concept in the Context of a Lifestyle Intervention

Past research indicates self-efficacy and supervised exercise are effective interventions for prevention of chronic conditions. Despite well-known health improvements associated with moderate (MPA) and vigorous physical activity (VPA), less than 20% of US adults meet physical activity guidelines. Examination of psychosocial factors provide additional insights into lifestyle intervention participation and, subsequently, desired health outcomes. Health-related self-concept (HRSC) indicates positive (i.e., promote well-being) and negative (i.e., decrease adaptive health behavior) perceptions of health. The purpose of this study was to examine the relationship between Lifestyle-HRSC questionnaire and physical activity. The Lifestyle-HRSC scale (79-items) was implemented within a 12-week type 2 diabetes prevention intervention. Data were gathered from 71 participants. Linear regressions were calculated to predict physical activity based on Lifestyle-HRSC items. From pre-intervention results, problem solving items predicted increased MPA. (e.g., F(1, 68) = 4.23, p = 0.04, R2 = 0.06). Physical activity, problem solving, and self-monitoring items predicted increased VPA (e.g., F(1, 68) = 10.97, p = 0.001, R2 = 0.14). Post-intervention data are being analyzed. Physical activity effectively prevents chronic conditions, including heart disease and type 2 diabetes. Psychosocial factors could enhance our understanding of adherence to physical activity guidelines. Physical activity, diet, social support, and behavior change techniques have been proven to contribute to greater success in interventions. To ensure successful participation and adherence to physical activity, it is important for providers to understand these factors. Lifestyle-HRSC may provide an innovative screening to distinguish among participation in moderate and vigorous physical activity.
