Everyday moderate-to-vigorous physical activity in stroke survivors: the role of individual and joint intentions and self-efficacy

Corroborate and extend previous evidence on individual intentions and self-efficacy for moderate-to-vigorous physical activity in a sample of stroke survivors. Examine associations between joint (with their romantic partner) intentions and self-efficacy for moderate-to-vigorous physical activity. For up to 14 consecutive days, 88 stroke survivors (Mage = 67.84, SD = 10.79; 73% male; 35% with college degree; 82% White) reported their individual and joint intentions and self-efficacy in the morning, minutes engaged in moderate-to-vigorous physical activity in the evening and wore physical activity monitors. Individual self-efficacy was not related to moderate-to-vigorous physical activity, but individual intentions were associated with higher self-reported moderate-to-vigorous physical activity minutes. Joint variables (intentions and self-efficacy) were found to predict self-reported moderate-to-vigorous physical activity minutes, but not accelerometer-measured moderate-to-vigorous physical activity. Findings shed light on when and how individual intentions and intentions involving one's spouse are beneficial for moderate-to-vigorous physical activity among individuals living with the effects of a stroke.
