Adolescents' self-reported problems as predictors of psychopathology in adulthood: 10-year follow-up study

BACKGROUND: Knowledge of the course of psychopathology from adolescence into adulthood is needed to answer questions concerning origins and prognosis of psychopathology across a wide age range. AIMS: To investigate the 10-year course and predictive value of self-reported problems in adolescence in relation to psychopathology in adulthood. METHOD: Subjects from the general population, aged 11-19 years, were assessed with the Youth Self-Report (YSR) at initial assessment, and with the Young Adult Self-Report (YASR), the Composite International Diagnostic Interview (CIDI) and three sections of the Diagnostic Interview Schedule (DIS) 10 years later. RESULTS: Of the subjects with deviant YSR total problem scores, 23% (males) and 22% (females) had deviant YASR total problem scores at follow-up. Subjects with initial deviant YSR total problem, internalising and externalising scores had higher prevalences of DSM-IV diagnoses at follow-up. CONCLUSIONS: Adolescent problems tended to persist into adulthood to a moderate degree. High rates of problems during adolescence are risk factors for psychiatric disorders in adulthood.
