Highly satisfying social relationships make us happy and healthy-they fill us with joy and a sense of meaning and purpose. But do all the relationships in our lives contribute equally to our well-being and do some people benefit more from certain relationships? The current study examined associations between the satisfaction of specific relationships within a family (i.e., with parents, siblings) and adjustment (i.e., life satisfaction and depressive symptoms) among 572 emerging adults aged 18-25 ( M age = 19.95, SD = 1.42; 77.4% female). Overall, relationship satisfaction with mothers and fathers was associated with better adjustment. Attachment anxiety and avoidance moderated associations between relationship-specific satisfaction and adjustment. We discuss the findings in the context of the shifting of attachment functions during emerging adulthood and the dynamic nature of close relationships across the lifespan.
