Adolescents with severe disruptive behaviour have an elevated risk for adult psychosis. We investigated whether the Structured Interview for Prodromal Syndromes (SIPS) is a useful psychosis risk-screening tool for adolescents with disruptive behaviour.
Fifty-three adolescents residing in a reform school due to severe behavioural problems were interviewed with SIPS to ascertain clinical high-risk (CHR) state. CHR status was compared to self-reported psychiatric problems, and to registry data on hospital treatments for mental health disorders during a 5-year follow-up time.
CHR was associated with self-reported internalizing problems and thought problems. It failed to predict psychoses but was associated with hospital treatment for mood and conduct disorders.
The SIPS interview has limited power for predicting psychosis among adolescents with severe behavioural problems. However, SIPS appears to be useful for screening and predicting other psychiatric problems.
