目的：研究社会认知因素（自我效能和影响）在预测老年人样本（N = 174）长期体力活动中的作用。设计图：一项前瞻性设计评估了6个月随机对照运动试验后2年和5年的体力活动和心理社会变量。主要结局指标：主要结果变量是自我报告的体力活动，以前的行为，自我效能和影响评估的决定因素的体力活动。结果：协方差模型分析表明，第2年的体力活动是5年随访时体力活动的最强预测因子。第2年的自我效能和情感也与第5年的体力活动相关，这与原始治疗条件相同。变量占第5年活动方差的35%。结论：在第二年时，身体活动水平较高、积极情绪较高和自我效能感较高的老年人更有可能在第五年继续活跃。这项研究是对老年人运动行为的最长随访之一，对构建环境以最大限度地维持体力活动具有意义。
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.
