Background: When examining older adults' health behaviors and psychological health, it is important to consider the social context.
Purpose: The purpose of this study was to examine in older adult marriages whether each spouse's physical activity predicted changes in their own (actor effects) and their partner's (partner effects) depressive symptoms. Gender differences were also examined.
Method: Each spouse within 1260 married couples (at baseline) in the Cardiovascular Health Study completed self-report measures at wave 1 (1989-1990), wave 3 (1992-1993), and wave 7 (1996-1997). Dyadic path analyses were performed.
Results: Husbands' physical activity significantly predicted own decreased depressive symptoms (actor effect). For both spouses, own physical activity did not significantly predict the spouse's depressive symptoms (partner effects). However, husbands' physical activity and depressive symptoms predicted wives' physical activity and depressive symptoms (partner effects), respectively. Depressive symptoms did not predict physical activity.
Conclusion: Findings suggest that husbands' physical activity is particularly influential for older married couples' psychological health.
