Targeted Rejection Predicts Hastened Onset of Major Depression

Abstract

Although severe life stress frequently precipitates the onset of major depression, little is known about the basic nature of stressors in this general category of adversity and how exposure to different life events might be related to clinical aspects of the disorder. We addressed this issue by introducing, and examining the effects of, targeted rejection (TR), which involves the exclusive, active, and intentional social rejection of an individual by others. Twenty-seven adults with major depressive disorder were administered an interview-based measure of life stress. Severe life events that occurred prior to the onset of depression were subsequently coded as TR or as non-TR. Participants who experienced a pre-onset severe TR event became depressed approximately three times faster than did their non-TR counterparts. These findings highlight the potential importance of TR as a marker of hastened depression onset and demonstrate how refining characterizations of stress may advance our understanding of depression.
