Age Differences in Stress, Social Resources, and Well-Being in Middle and Older Age

The present study examines the interrelationships among the constructs of social resources, stress, and well-being in middle-aged and older adults. Two samples of 489 middle-aged adults (41-43 years) and 449 older adults (61-63 years) from the Interdisciplinary Longitudinal Study of Adult Development were compared with respect to the availability of social resources, levels of stress, and well-being. The data were used to construct separate structural equation models explaining the influence of stress and social resources on well-being in the two groups. The results indicate higher levels of health-related stress and similar levels of social resources in the older group. Structural equation models and examination of total and indirect effects confirmed that a stress-suppression model has the best fit in explaining the interrelationships between stress, social resources, and well-being. There was a strong effect of stress on well-being, no direct effect of social resources on well-being, and a mediating effect of stress on well-being. The relative contributions of stress and resources to well-being were comparable between age groups.
