Early adversity and depressive symptoms among early adolescent girls: the mediating role of exposure to recent interpersonal acute stress.

Early adversity confers risk for depression in part through its association with (i.e., proximal) acute stress. However, it remains unresolved whether: a) early adversity predicts increases in recent acute stress over time; b) all - or only certain types - of recent events mediate the relationship between early adversity and depression; and c) early adversity places individuals at greater risk for depression via greater to independent (i.e., fateful) interpersonal events or via greater of dependent (i.e., partially self-initiated) interpersonal events (i.e., stress generation) or both. These questions were examined in a 3-wave longitudinal study of early adolescent girls ( = 125; = 12.35 years [ = .77]) with no history of diagnosable depression using contextual life stress and diagnostic interviews. Path analyses indicated that increases in past-year acute interpersonal, but not non-interpersonal, stress mediated the link between early adversity and depressive symptoms. The mediating role of interpersonal events was limited to independent ones, suggesting increases in interpersonal event , not interpersonal , acted as a mediator. Finally, findings support prior evidence that early adversity may not directly predict future depressive symptoms. Implications for understanding the role of recent stress in the association between early adversity and adolescent depression are discussed.
