Older adults’ physical activity-related social control and social support in the context of personal norms

This study investigated whether perceived physical activity norms moderated the effects of physical activity-related social interactions on intentions to engage in physical activity among community-residing older adults (N = 217). Structural equation modeling tested whether two types of social support and social control interacted with personal norms in predicting intentions to be active. Emotional and informational support were associated with higher intentions, and negative social control was associated with lower intentions to engage in activity. Each of these effects was more prominent in the context of weak personal norms, suggesting future research and interventions should consider joint effects of support and norms.
