Developmental influences on interpersonal stress generation in depressed youth

This research tested the hypothesis that the transition through adolescence, particularly undergoing puberty early relative to one's peers, would amplify the effect of depression on the subsequent generation of interpersonal stress. This hypothesis was examined in 158 youth (M age=12.39 years, SD=1.21) using semistructured interviews of depression and life stress. Three indexes of development--chronological age, pubertal status, and pubertal timing--were examined as possible moderators of the stress-generation effect. As anticipated, depression predicted interpersonal stress generation in early-maturing but not late-maturing youth. These findings provide an important developmental context for theory and research on stress generation.
