Are cognitive errors of underestimation predictive or reflective of depressive symptoms in children: a longitudinal study.

Children in Grades 3-8 participated in a longitudinal study of the relation between negative self-evaluation errors and symptoms of depression. Children's self-perceived competence in 5 domains (academic, social, athletic, appearance, and conduct) was compared with teachers' and peers' perceptions. Children's tendency to underestimate their competencies predicted increases in depression scores in only 1 of 6 grade levels. Children's depression scores predicted increases in the underestimation of self-competence over time in all grade levels. Gender differences and developmental differences in the cognitive errors associated with depression scores also emerged. Contrary to A. T. Beck's (1963, 1972) model, negative self-distortions appear to be more reflective than predictive of depression in children.
