Predictors and pathways from infancy to symptoms of anxiety and depression in early adolescence.

Abstract

Data from a prospective 11-year longitudinal survey were used to identify early predictors and pathways to symptoms of anxiety and depression at 12-13 years of age, and to examine whether there were unique predictors of anxious versus depressive symptoms. Structural equation modeling was used to explore longitudinal relations between contextual (maternal distress, family adversities, and social support) and temperamental (shyness and emotionality) risk factors in their prediction of informant-consistent symptoms of anxiety and depression. The results show that early risk factors can explain 38% of the variance in boys' covarying symptoms of anxiety and depression in early adolescence, and 25% of variance in girls' covarying symptoms. Two main pathways were identified. One pathway was through temperament, as nearly all risk factors were partly mediated through child emotionality in midchildhood. Another pathway was through early contextual risk factors, with all direct and indirect contextual impact from before 5 years of age. Family adversity uniquely predicted depressive symptoms. These findings underscore the persisting impact of contextual predictors in families with children less than 5 years of age. The importance of early interventions to prevent adolescent internalizing problems is stressed.
