Motivation is a frequently reported but far less studied driver for post-stroke physical activity participation. Motivation and physical activity may be important contributors to the prevention management and alleviation of affective symptoms among stroke survivors.
To investigate the real-time associations between motivation, physical activity, and affect in the daily lives of community-dwelling stroke survivors using ecological momentary assessment (EMA) and accelerometry.
Forty community-dwelling stroke survivors wore an accelerometer on the thigh and completed EMA surveys assessing motivation (autonomous motivation, controlled motivation) and affect (negative affect, positive affect) eight times daily for 7 days. Multivariate regression analysis and multilevel modeling investigated the associations between motivation, physical activity, and affect.
Greater autonomous motivation for physical activity was associated with less sedentary behavior (β = -0.40, p = .049) and more moderate-to-vigorous physical activity (β = 0.45, p = .020) participation in daily life. Greater autonomous motivation was momentarily associated with less depressed affect (β = -0.05, p < .001) and greater positive affect (β = 0.13, p < .001). Moreover, greater controlled motivation was momentarily associated with greater depressed affect (β = 0.06, p < .001). More intense physical activity was momentarily associated with greater positive affect (β = 0.13, p = .016). No moderating effect of motivation on the association between physical activity and affect was found.
Motivation and physical activity are momentarily associated with affect among stroke survivors. Assessing and fostering autonomous motivation may be beneficial for promoting physical activity and managing positive and depressed affect as stroke survivors return to the community.
动机是中风后参与体育活动的一个经常被提及但研究较少的驱动因素。动机和体育活动可能是中风幸存者情感症状预防、管理和缓解的重要因素。
使用生态瞬时评估（EMA）和加速度计研究社区居住中风幸存者日常生活中动机、体育活动和情感之间的实时关联。
40名社区居住的中风幸存者在大腿上佩戴加速度计，并在7天内每天完成8次EMA调查，评估动机（自主动机、受控动机）和情感（消极情感、积极情感）。多变量回归分析和多层次建模研究了动机、体育活动和情感之间的关联。
更高的体育活动自主动机与日常生活中更少的久坐行为（β = -0.40，p = .049）和更多的中度至剧烈体育活动（β = 0.45，p = .020）参与相关。更高的自主动机与瞬间更少的抑郁情感（β = -0.05，p < .001）和更高的积极情感（β = 0.13，p < .001）相关。此外，更高的受控动机与瞬间更高的抑郁情感（β = 0.06，p < .001）相关。更剧烈强度的体育活动与瞬间更高的积极情感（β = 0.13，p = .016）相关。未发现动机对体育活动与情感之间关联的调节作用。
动机和体育活动与中风幸存者的情感瞬间相关。评估和培养自主动机可能有利于促进体育活动以及在中风幸存者回归社区时管理积极和抑郁情感。
