Abstract
The common etiology hypothesis proposes that depression and anxiety commonly co-occur because they share etiological factors. This study examined the specificity of the hopelessness theory in the development of depressive and anxious symptoms in children. Students in Grades 3 through 6 (N = 418, 47% boys) completed measures assessing inferential styles about causes, consequences, and the self, depressive symptoms, and anxious symptoms. Six weeks later, children completed measures of depressive symptoms, anxious symptoms, and hassles. All 3 inferential styles interacted with hassles to predict increases in depressive symptoms, although this relation only held for children with low levels of initial symptoms. Inferential styles about consequences and the self also predicted increases in anxious symptoms. Consistent with the common etiology hypothesis, after controlling for the association between depressive and anxious symptoms, the effects of inferential styles about consequences and the self persisted.
