This study determined the effectiveness of a self-efficacy intervention designed to improve self-efficacy and physical activity in older adults postcardiac event. An experimental three-group design tested the intervention, with treatment groups receiving 1 of 2 supportive telephone protocols (theory-based self-efficacy coaching or attention control). Outcome variables included self-efficacy expectations for physical activity (PA), self-reported PA, and PA performance (distance walked in 6 minutes). The self-efficacy intervention was effective in demonstrating greater PA performance when compared to the attention control intervention, and PA self-efficacy was significantly correlated with both measures of PA. There were significant main effects of time for PA self-efficacy and distance walked, and a significant interaction effect on the distance walked because of time and treatment condition. Although the self-efficacy intervention did not show a direct effect on level of PA self-efficacy as hypothesized, there was an indirect interaction effect on distance walked and physical activity confidence.
本研究确定了一种自我效能干预措施的有效性，该措施旨在提高心脏病发作后老年人的自我效能和身体活动水平。采用实验性三组设计对该干预措施进行测试，治疗组接受两种支持性电话协议中的一种（基于理论的自我效能指导或注意力控制）。结果变量包括身体活动（PA）的自我效能期望、自我报告的PA以及PA表现（6分钟内行走的距离）。与注意力控制干预相比，自我效能干预在提高PA表现方面更有效，并且PA自我效能与PA的两项测量指标均显著相关。PA自我效能和行走距离在时间上有显著的主效应，并且由于时间和治疗条件对行走距离有显著的交互效应。尽管自我效能干预并未如假设的那样对PA自我效能水平产生直接影响，但对行走距离和身体活动信心有间接的交互效应。
