Comorbidity among Childhood Anxiety Disorders

This paper reports on 73 consecutive admissions to an outpatient anxiety disorder clinic for children and adolescents. Patients were evaluated with a structured diagnostic interview for primary and secondary disorders with DSM-III criteria in order to examine patterns of comorbidity. The most common primary diagnoses for the sample included separation anxiety disorder (33%), overanxious disorder (15%), social phobia of school (15%), and major depression (15%). Children with a primary diagnosis of separation anxiety disorders were most likely to receive a concurrent diagnosis of overanxious disorder. Alternatively, children with a primary diagnosis of overanxious disorder were most likely to receive an additional diagnosis indicative of a social anxiety problem, either social phobia or avoidant disorder. Children with a primary major depression most often exhibited social phobia and/or overanxious disorder. No clear-cut pattern of comorbidity emerged for the social phobic (school) group. These findings are discussed in terms of their comparability with results recently obtained from an adult anxiety clinic population.
