The OPUS YOUNG Trial. Early Intervention Versus Treatment as Usual for Adolescents With First-episode Psychosis

The OPUS YOUNG (OY) study investigates the efficacy of early intervention service versus treatment as usual (TAU) for adolescents aged 12-17 years with a first-episode psychosis. In Denmark, the yearly incidence of schizophrenia in youth below the age of 18 years has increased from 137 in 2000 to 477 in 2016. Outcomes in people with schizophrenia spectrum disorders are suboptimal with low quality of life, low rates of recovery, substance misuse, higher rates of suicide, violence and legal problems, low educational and vocational attainment, and a significantly reduced life-expectancy of 15-20 year. Schizophrenia imply a large burden of disease with severe impact on patients, their families, the service system and a large economic societal burden. The investigators will include 290 participants age 12-17 years with an early onset psychosis within the following diagnostic classes: schizophrenia spectrum, psychotic depression or drug-induced psychosis. The design is an independent, investigator initiated, pragmatic, randomized clinical trial, with blinded outcome assessment. Participants are randomized 1:1 to OY or TAU. Participants in OY are offered 2 years of specialized intervention (OY) regardless of age, while participants in TAU are switched to adult psychiatry at the age of 18 years. OY builds on the Danish evidenced based intervention for young adults, OPUS, adjusted to meet the specific needs of adolescents: intensified support for caretakers and relatives including siblings; social cognition and interaction treatment; and individual cognitive behavioral case management. OY addresses the specific challenges of psychopharmacologic treatment in youth; supported transition to adult care after OY; school or educational support; and prevention and treatment of substance misuse. The primary endpoint is improved functioning in daily and social life after 24 months. Secondary outcome measures are psychopathology, quality of life, family stress, and retention in treatment and school/employment, and healthcare consumption. The clinical and societal perspective of a large scale implementation is improved prevention of the negative consequences of early-onset psychosis and a reduced burden of severe mental illness.
