To investigate the incidence, transition probabilities, and risk factors for obsessive-compulsive disorder (OCD) and subclinical OCD in adolescents.
A two-stage epidemiological study originally designed to investigate depression was conducted between 1987 and 1989 in the southeastern United States.
For the screening, a self-report depressive symptom questionnaire was administered to a community sample of 3,283 adolescents.
In the diagnostic stage, the Schedule for Affective Disorders and Schizophrenia for School-Age Children was administered to 488 mother-child pairs.
Baseline screening and diagnostic data from the first year the subject completed an interview and follow-up diagnostic data from subsequent years were used.
The 1-year incidence rates of OCD and subclinical OCD were found to be 0.7% and 8.4%, respectively.
Transition probabilities demonstrated a pattern of moving from more severe to less severe categories.
Of those with baseline OCD, 17% had the diagnosis of OCD at follow-up ; 62% moved to the referent group.
Of those with baseline subclinical OCD, 1.5% had OCD at follow-up and 75% moved to the referent group.
Black race (odds ratio [OR]=23.38), age (OR=4.02), desirable life events (OR=0.78), undesirable life events (OR=1.21), and socioeconomic status (OR not estimable) were significant predictors of incident OCD.
Age (OR=2.30), desirable life events (OR=0.92), and undesirable life events (OR=1. (...)
