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.
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.

OPUS YOUNG is a two year out-patient specialized early intervention service for children and adolescents with a first episode psychosis. The OPUS YOUNG treatment consists of the following elements: modified assertive community treatment, low patients to case manager ratio, cognitive-behavioural case management (CBCM), psycho-educational family treatment including multiple family groups(MFG) and psychoeducational siblings groups, Social Cognition and Interaction Training (SCIT), possible individual Cognitive Behavioural Therapy (CBT) in addition to CBCM, and manual based psychopharmacologic treatment. Additional, special transition support, individual school/employment support, and prevention and treatment of substance abuse.
The patients allocated to TAU will be offered non-manualized treatment following national Danish guidelines and local guidelines. Treatment is provided by a multidisciplinary team and consists of case-management (no defined upper case load), family support and psychoeducation, in addition to psychopharmacological treatment. In some cases, social skills training and CBT may be offered. In general, office visits take place in outpatient clinics.

Personal and Social Performance Scale (PSP)
Change in the global score of social function, measured with Personal and Social Performance Scale (PSP). PSP provides a global score on a scale from 1-100, with lower scores indicating lower social functioning. The global score is based on scores on four subdomains (1. Socially useful activities, 2. Personal and social relationships, 3. Self-care, and 4. Disturbing and aggressive behaviour), rated on a 6-point Likert scale (1=absent to 6=very severe). The scoring of PSP is based on all available information and concerns the patient's daily level of functioning in the family, in school, and during leisure time during the past month. Higher global values mean better social function. Researchers will interview the participants prior to the scoring of PSP using a semi structured interview guide suitable for children and adolescents, developed by the OPUS YOUNG research team.

Severity of psychotic symptom dimension, SAPS
Scale for Assessing Psychotic Symptoms in Schizophrenia (SAPS), used to assess the phenomenological presentation of psychotic symptoms in schizophrenia, is a rating scale to measure positive symptoms in schizophrenia. The SAPS- scale is split into 4 sub-scales (hallucinations, delusions, bizarre behavior and formal thought disorder) each of which are rated from 0 (absent) to 5 (severe) and for each domain is also given a global symptom severity score by the rater. The Psychotic symptom dimension is the sum of global scores, divided by the number of global scores (range 0-5). The psychotic dimension is composed of scores of hallucination and delusions. Higher score indicates worse level of symptoms.

Severity of Negative symptom dimension, SANS
Scale for Assessing Negative Symptoms in Schizophrenia (SANS), used to assess the phenomenological presentation of negative symptoms in schizophrenia, is a rating scale to measure negative symptoms in schizophrenia. The SANS scale is divided into five sub-scales (affective flattening, alogia, avolition-apathy, anhedonia-asociality, attention), each of which are rated from 0 (absent) to 5 (severe) and for each domain is also given a global symptom severity score by the rater (global ratings). The Negative symptoms dimension is calculated as the sum of the global scores, divided by the number of global scores (range 0-5). The negative symptom dimension is composed of scores of anhedonia, avolition, affective flattening and alogia. Higher score indicates worse level of symptoms.
Time frame: Last month at baseline (from enrollment), at month 12, at month 24 and at month 30
Severity of disorganized symptom dimension
Severity of Disorganized symptom dimension is calculated as the sum of the global scores of formal thought disorder, bizarre and behaviors from Scale for Assessing Psychotic Symptoms in Schizophrenia (SAPS) and the score of inappropriate affects (item within the subscale for affective flattening) in Scale for Assessing Negative Symptoms in Schizophrenia (SANS) (range 0-5).Higher score indicates worse level of symptoms.

Client satisfaction questionnaire, CSQ
Patients satisfaction with the treatment is measured with the CSQ-scale. CSQ assess global client satisfaction, along with single dimension. The CSQ has eight question-items (quality of service, kind of service, met needs, recommend to a friend, amount of help, deal with problems, overall satisfaction, and come back). Patients respond to those question-items using a 4-point Likert scale. Their responses are scored from 1 to 4, and thus the possible total scores range from 8 to 32. Higher scores indicate greater satisfaction. Self-rapport
Time frame: Present time at month 12 and at month 24.
Quality of life, - Health Related Quality of Life Questionnaire for Children and Young People and their Parents, KIDSCREEN-10
The participants perception of their quality of life is assessed using the self-administered questionnaire KIDSCREEN-10. KIDSCREEN-10 contains 10 items: (1) Have you felt fit and well? (2) Have you felt full of energy? (3) Have you felt sad? (4) Have you felt lonely? (5) Have you had enough time for yourself? (6) Have you been able to do the things that you want to do in your free time? (7) Have your parent(s) treated you fairly? (8) Have you had fun with your friends? (9) Have you got on well at school? (10) Have you been able to pay attention? Participants respond to those question/items using a 5-point response scale. Answer categories item 1 and 9: not at all-slightly-moderately-very-extremely; all other items: never-seldom-quite often-very often-always. Responses are coded so that higher values indicate better QoL. A low score indicates a poor QOL, and a high score is indicative of a better QOL.
