Objectives: Using the Proactivity Model of Successful Aging, we examined how internal and external resources contribute to the maintenance of psychological well-being and social activities among older adults who experience normative stressors of aging. Outcome variables in this study are collectively referred to as quality of life (QOL). We also examined the mediating role of proactive adaptations between internal and external resources and QOL indicators.
Method: Based on five annual interviews of a sample of 1000 community-dwelling older adults in Florida (effective N = 561), we tested the lagged effects of stressors on two indicators of QOL, four years later. In the full longitudinal model, using structural equations, we estimated the direct effects of internal and external resources on QOL, along with indirect effects through proactive adaptations.
Results: Stressors negatively influenced QOL four years later. Internal and external resources led to better QOL four years later, both directly and indirectly through proactive adaptations of marshaling support and planning for the future.
Conclusion: These findings lend support to the Proactivity Model of Successful Aging by documenting the value of proactive adaptations (i.e., exercise, planning ahead, and marshaling support) as proximate influences on QOL outcomes (i.e., depressive symptomatology and social activities). Findings suggest that older adults can maintain successful aging even in the face of health-related and social stressors by invoking accumulated resources to deal actively with the challenges of aging.
