Objective: To examine the contribution of social-cognitive factors (self-efficacy and affect) in predicting long-term physical activity in a sample of older adults (N = 174). Design: A prospective design assessed physical activity and psychosocial variables at 2 and 5 years following a 6-month randomized, controlled exercise trial. Main Outcome Measures: The primary outcome variable was self-reported physical activity, with previous behavior, self-efficacy, and affect assessed as determinants of physical activity. Results: Covariance modeling analyses indicated that physical activity at Year 2 was the strongest predictor of physical activity at 5-year follow-up. Both self-efficacy and affect at Year 2 were also associated with physical activity at Year 5, as was original treatment condition. Variables accounted for 35% of the variance in Year 5 activity. Conclusion: Older adults with higher levels of physical activity, more positive affect, and higher self-efficacy at Year 2 were more likely to continue to be active at Year 5. This study is one of the longest follow-ups of exercise behavior in older adults and has implications for structuring environments to maximize the maintenance of physical activity.

In this study, the pattern and correlates of physical activity-related well-being in older adults (N = 174; men = 49, women = 125; mean age = 66 years) were examined across a 6-month exercise trial. Baseline levels of self-efficacy fitness, importance of physical activity, and social support and exercise participation across the trial were used as correlates of positive and negative feeling states. Psychological responses to physical activity were assessed on a bimonthly basis across the trial. Latent growth curve analyses indicated significant growth in positive well-being over the 6-month period, with increases reaching a threshold at 4 months. Self-efficacy was inversely related to change in positive well-being across the trial. Frequency of activity and increases in well-being over the trial were significant predictors of self-efficacy at program termination. Findings suggest the social cognitive context of the exercise experience may have influence on exercise-related well-being. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献
