| Abstract |
Background Early symptoms of emerging psychiatric problems in adolescence are often unstable and co-occur. The dynamic character of these symptoms impedes not only the diagnostic process but also complicates indicating an appropriate intervention. Prevention programs mainly focus on specific symptom reduction while, considering the nature of early psychiatric symptoms, a transdiagnostic intervention may be more appropriate. This study aims to examine the effectiveness of a school-based transdiagnostic intervention targeting mechanisms of early psychiatric symptoms. Method The intervention was conducted among adolescents (n = 80, mean age = 12.5) reporting persistent elevated psychosocial problems for a period of 12 months. Participants received an 8-session program containing elements of empowerment and cognitive bias modification. Psychotic experiences, symptoms of depression and anxiety, as well as emotional and behavioural problems were assessed before the intervention, immediately after the intervention and at six months follow-up. Self-esteem and locus of control were included in Generalized Estimating Equations analyses as mediators. Results Results showed decrease of psychotic, anxiety and depression symptoms immediately after intervention and at follow-up. Psychosocial problems (emotional, behavioural and peer problems and hyperactivity) decreased only at follow-up. No mediating effects of locus of control and self-esteem were found. Conclusions Findings provide initial support for efficacy of a school-based transdiagnostic intervention for persistent early psychiatric symptoms. As a next step, randomized controlled trials and more insights on mechanisms of transdiagnostic interventions are needed. |
