Functional versus structural social support, desirable events, and positive affect in older adults.

Abstract

The independent contributions of structural social support versus functional support to positive affect in older adults were compared in this prospective design. Four social support models were translated from the stress-symptoms literature into promotional models for positive mental health and for relationships to desirable challenge events. A total of 1,031 older adults were interviewed 5 times at 6-month intervals, and events were measured across the middle 18-month period. The 2 support variables made quite different contributions. Functional support was directly related to positive affect 2 years later, independent of events; structural support had more transitory direct effects. Structural support, but not functional support, was related to the subsequent occurrence of challenge events and in turn was strengthened by challenge events, suggesting a dynamic interplay between the social network and desirable events.
