The authors examined spouses' provision of health-related support and control as predictors of health behavior and mental health among patients participating in cardiac rehabilitation (N = 94 couples). Cross-sectional analyses revealed that spouses' support was positively associated with patient health behavior. Prospective analyses of change over 6 months (N = 65 couples) revealed that spouses' support predicted increased patient mental health, whereas spouses' control predicted decreased patient health behavior and mental health. Findings suggest that spouses' efforts to facilitate patients' healthy lifestyle behaviors are associated with patients' health behavior and mental health, but not always as spouses might intend.

Our findings offer insight into partners' day-to-day disease-related interactions and identify those that are likely to be beneficial versus detrimental for patients' physical and psychological health.

Discussion integrates solidarity theory, developmental stake, and contingency theory. Most middle-aged adults provide more to grown offspring than to parents, consistent with their greater stake in their progeny. Middle-aged adults also respond to crises (i.e., parental disability) and everyday needs (i.e., offspring student status) in providing intergenerational support, in accordance with contingency theory.

The positive effect of activities on well-being is proposed to be mediated by self-conceptualizations and facilitated by socioeconomic status. The hypothesized processes were estimated with LISREL VIII using data from a large cross-sectional survey with a sample of 679 adults aged 65 and older who were representative of older adults living in the Detroit area. Findings indicate that the frequency of performing both leisure and productive activities yields an effect on physical health and depression and that these effects are mediated in part by a sense of self as agentic, but less clearly by a sense of self as social. Furthermore, socioeconomic status, operationalized as formal educational attainment, facilitates the effect of leisure to a greater extent than that of productive activities.

Findings suggest that spousal exercise support on its own or in conjunction with spousal exercise control may facilitate daily diabetes management through physical activity.
