The authors used an epidemiologic approach to investigate rates, symptoms, and behavioral concomitants of anxiety across the child and adolescent age span. They drew 210 children aged 8, 12, and 17 in equal numbers from a community sample and evaluated them with structured diagnostic assessments. They found anxiety to be the most frequently reported type of psychopathology across all three age groups. Although the prevalence of any anxiety symptom remained constant, specific types of anxiety varied with age. Age differences in nonanxiety behavior were found between subjects with and without anxiety, particularly with regard to interpersonal dysfunction.
