Werner's orthogenetic principle states that human behavior proceeds from a state of global diffuseness to one of articulated complexity, and that as individuals develop, their responses to the environment become more specific and more differentiated. The present study evaluated this hypothesis, in relation to psychopathology in general and depression in particular. Child Behavior Checklist responses for 1, 345 outpatient and inpatient children and adolescents were compared along two developmental dimensions: age and clinical severity. Results failed to support the hypothesis that the psychopathology in general is more differentiated among older and more severely disturbed children. The findings did indicate, however, that depression was more distinct among the older, more severely disturbed subjects. Finally, little evidence of a categorical depression was found in any of the four age by severity groups.
