Social Support and Strain from Different Relationship Sources: Their Additive and Buffering Effects on Psychological Well-Being in Adulthood

Abstract

The present study examined the main and interactive effects of relationship-specific (i.e., spouses, friends, parents, and children) social support and strain on positive (happiness and well-being) and negative (loneliness and depressive symptoms) psychological well-being, and whether the associations varied by age and gender. A dataset was collected from 1033 adults (20–69 years; 50.1% female) from South Korea regarding social support and strain and indicators of psychological well-being. Results revealed that spousal and friend support was associated with enhanced happiness and well-being and reduced loneliness, whereas spousal and friend strain was associated with heightened depressive symptoms. Relationship-specific social support and strain showed interactive effects. Social support from parents and spouses buffered the adverse effects of social strain on psychological well-being, but their protective effects diminished when they experienced high levels of parental or spousal strain. These patterns were dependent on age and gender, with protective effects of friend support being greater for younger adults and women than for older adults and men.
