The purpose of this study was to examine the within-day and cross-day prospective effects of knee osteoarthritis (OA) patients' self-efficacy to engage in physical activity despite the pain on their subsequent physical activity assessed objectively in their natural environment.
Over 22 days, 135 older adults with knee OA reported their morning self-efficacy for being physically active throughout the day using a handheld computer and wore an accelerometer to measure moderate activity and steps.
Morning self-efficacy had a significant positive effect on steps and moderate-intensity activity throughout that day, above and beyond the effects of demographic background and other psychosocial factors as well as spouses' support and social control. The lagged effect of morning self-efficacy on the next day's physical activity and the reciprocal lagged effect of physical activity on the next day's self-efficacy were not significant. Positive between-person effects of self-efficacy on physical activity were found.
Future research should aim to better understand the mechanisms underlying fluctuations in patients' daily self-efficacy, and target patients' daily self-efficacy as a modifiable psychological mechanism for promoting physical activity. (PsycINFO Database Record
本研究旨在探讨膝骨关节炎（OA）患者尽管疼痛但参与体育活动的自我效能感在自然环境中对其后续客观评估的体育活动的日内和跨日前瞻性影响。
在22天的时间里，135名患有膝骨关节炎的老年人使用手持电脑报告他们全天进行体育活动的早晨自我效能感，并佩戴加速度计来测量中等强度活动和步数。
早晨自我效能感对当天的步数和中等强度活动有显著的积极影响，超出了人口统计学背景、其他心理社会因素以及配偶支持和社会控制的影响。早晨自我效能感对次日体育活动的滞后效应以及体育活动对次日自我效能感的相互滞后效应并不显著。发现自我效能感对体育活动存在个体间的积极影响。
未来的研究应旨在更好地理解患者日常自我效能感波动背后的机制，并将患者的日常自我效能感作为促进体育活动的一种可调节心理机制加以关注。（PsycINFO数据库记录）
