This longitudinal study examined how depressive symptoms relate to children's self-perceptions and to estimates of children's cognitive distortions about the self in a nonclinical sample of children who were followed from 4th grade (n ϭ 248) through 6th grade (n ϭ 227). Report card grades measured children's academic competence, and teachers' ratings of children's level of peer acceptance at school indicated social acceptance. Self-reported depressive symptoms predicted a change in children's negative views of the self. Moreover, the self-perceptions of children who exhibited more symptoms of depression appeared to reflect an underestimation of their actual competence. Children's negative self-perceptions and underestimations about the self were not associated with a subsequent change in depressive symptoms. The implications of the findings for cognitive theories of depression and future research with this population are discussed.Cognitive theory suggests that cognitions, particularly negative beliefs about the self, are related to the etiology of depression (Beck, 1967(Beck, , 1976. Two of the most basic assumptions of the theory, (a) that cognition has causal priority over emotions and (b) that depressed children's negative beliefs about the self reflect distortions of reality, have rarely been tested in the childhood depression literature (for reviews, see Garber, Quiggle, & Shanley, 1990;Hammen, 1990). The current study used a prospective longitudinal design to test associations between depressive symptoms and two dimensions of children's self-perceptions: the overall evaluation of the self and the accuracy of that judgment. First, we tested whether negative self-perceptions are associated with subsequent increases in signs of depressive symptoms or whether the reverse is true (i.e., depressed mood predicts a more negative view of the self). Second, estimating negative biases in children's judgments about the self, we examined whether underestimations of competence are a risk factor for future depressive symptomatology. The reverse causal model was also tested.
