context: UNASSIGNED: Although @entity3 symptom severity and impairment are overlapping but nevertheless distinct illness parameters, little research has examined whether variables found to be associated with the severity are also correlated with symptom-induced impairment. Parents and teachers completed ratings of symptom-induced @entity2 , and parents completed a background questionnaire for a consecutively referred sample of primarily male (81  %) 6-to-12  year olds with @entity1 ( @entity1 ) (N   =   221). Some clinical correlates (e.g., IQ   <   70, maternal level of education, pregnancy complications, current use of psychotropic medication, season of birth) were associated with @entity2 , whereas others were correlated with only a few syndromes (e.g., gender, co-morbid medical conditions) or were not related to @entity2 (e.g., family psychopathology). There was little convergence in findings for parents' versus teachers' ratings. Some clinical correlates (e.g., season of birth, current psychotropic medication, maternal education) were unique predictors of three or more disorders. Pregnancy complications were uniquely associated with social @entity4 and @entity9 symptom-induced impairment. IQ was a unique predictor of @entity5 , @entity1 , @entity8 symptom-induced impairment. @entity0 whose mothers had relatively fewer years of education had greater odds for symptom-induced @entity2 , @entity7 , @entity3 , and @entity6 and greater number of impairing conditions. Season of birth was the most robust correlate of symptom-induced impairment as rated by teachers but not by parents. @entity0 born in fall evidenced higher rates of co-occurring @entity3 and @entity1 symptom-induced @entity2 of impairing conditions. Many variables previously linked with symptom severity are also correlated with impairment.
