Longitudinal dynamics of depressogenic personality and attachment dimensions in adolescence: an examination of associations with changes in depressive symptoms.

Depressogenic personality and attachment are two major factors related to the development of adolescents' depressive symptoms. However, no previous longitudinal studies have examined simultaneously both vulnerability factors in relationship to depressive symptoms. The present study examined associations between intra-individual change in adolescents' depressogenic personality orientations (i.e., sociotropy and autonomy), dimensions of mother-adolescent attachment (i.e., anxiety and avoidance), and depressive symptoms. The sample of the present research consisted of 289 high school students (mean age = 12.51 years at Time 1, 66% female) participating in a 3-wave cohort-sequential design. Latent growth curve modeling revealed no significant intra-individual change in depressogenic personality orientations but significant changes in dimensions of attachment and symptoms of depression. Initial levels of sociotropy were not related significantly to changes in attachment dimensions and depressive symptoms. High initial levels of autonomy were associated with increases in attachment anxiety, attachment avoidance, and depressive symptoms. In addition, results suggested that the association between initial levels of autonomy and increases in depressive symptoms was mediated by increases in attachment anxiety and avoidance. The discussion focuses on the status of depressogenic personality and attachment as risk factors for depression.
