Study Summary

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.

Study Description

The overarching purpose of the OPUS YOUNG trial is to improve the treatment and outcome of first-episode psychosis (FEP) in children and adolescents. We will address this ambition by testing the hypothesis, that Early Intervention Services (EIS) is superior compared to standard care in the treatment of children and adolescents below age 18 years with first-episode psychosis. The hypothesis is based on extrapolation of research showing that EIS is superior to standard care in the treatment of adults with first-episode psychosis with regards to symptom reduction, function improvement, adherence to treatment, lower hospitalization risk, improved recovery, and higher cost-effectiveness. However, no trials have investigated EIS in samples of patients below age 18 years. We will compare the efficacy and cost-effectiveness of EIS to treatment as usual (TAU) in adolescents aged 12-17 years (both inclusive) with first-episode psychosis. We will build on a Danish evidence-based intervention developed for young adults (OPUS) and adjust the concept to meet the specific needs of children and adolescents with early onset psychosis (OPUS YOUNG). The OPUS treatment is a coordinated and integrated manualized multimodal treatment building on three core elements: modified assertive community treatment with a low patient-case manager ratio; psychoeducational family intervention; and social skills training (SST). In OPUS YOUNG we will adjust the OPUS program to fit our younger age group by: 1) intensifying the support for caretakers and relatives including siblings, 2) instead of SST we are introducing social cognition and interaction treatment (SCIT), 3) providing individual cognitive behavioural case management (CBCM) to all participants and cognitive behavioural therapy (CBT) when needed, 4) addressing the specific challenges of psychopharmacologic treatment in adolescents by providing a treatment algorithm, 5) providing intensive supported transition of care (when patients approach transition to adult mental health services), 6) providing individualized school support, and 7) providing integrated prevention and treatment of substance misuse. Based on sample size estimation, we will include a minimum of 284 participants (maximum 304) and randomize them 1:1 to a two-year intervention of OPUS YOUNG versus TAU. We will conduct blinded assessment of treatment effects after 12 months and at treatment endpoint at 24 months. A further follow-up assessment will be performed to evaluate the sustainability of the intervention effects at six months after transition from OPUS YOUNG to TAU. Our primary outcome at treatment endpoint will be social function measured with Personal and Social Performance Scale (PSP). Secondary key outcomes measures are positive and negative symptoms, client satisfaction, and health related quality of life. Further outcomes are the broader psychopathology, cognitive functioning, social cognition, self-efficacy, experience of service, treatment alliance and adherence, the use of pharmacotherapy, school adherence, family burden, siblings' perceived stress, substance misuse, adverse treatment effects, and health economic measures.
