Conditions
Summary
This randomized controlled trial aims to evaluate the effectiveness of participation in five different STIME (Strengthened Cross-Sectoral Initiative for Children and Young People's Mental Health) interventions: 'Signs of Disordered Eating', 'Signs of Internalizing', 'Signs of Self-Harm', 'Take the Control Back', and 'The Parent Pilots'. The hypothesis is that participation in one of these interventions will be more effective than Management As Usual (MAU). Each intervention consists of three core components: early identification and screening, therapy based on evidence-informed manuals, and support within the child's learning environment.

- Symptoms meeting criteria for specialized psychiatric treatment
- Has another psychiatric disorder that requires assessment or is not adequately managed
- Has difficulties other than obsessive thoughts and behaviors that currently constitute the primary burden, and which must be addressed first
- Has previously received OCD treatment within psychiatric care (may be offered STIME if assessed but not treated due to mild severity)
- Has an increased or acute risk of suicide
- Has low functioning for other reasons, e.g., significantly reduced cognitive functioning
- 'the Parent Pilots'

Interventions
A manual-based family intervention for children and adolescents (10-17 years) experiencing overwhelming thoughts about food and body image, without meeting criteria for a diagnosed eating disorder. The intervention spans 2-3 months and consists of 5-10 sessions. A STIME therapist from the child's local municipality conducts the sessions with either the parents alone (for children aged 10-12 years) or with the whole family (for children aged 13-17 years). The intervention is based on family-based therapy, emphasizing the parents' role in supporting their child's healthy development. The intervention focuses on presentation of difficulties and change, incorporating elements from Cognitive Behavioral Therapy (CBT), including externalization, validation, and skills training. Practical strategies are applied through homework assignments, goal setting, and self-monitoring.
A manual-based intervention targeting adolescents (12-17 years) with self-harming thoughts and behaviors not requiring specialized psychiatric care. The intervention involves 9 sessions delivered by a trained STIME therapist, with both joint and individual sessions involving the adolescent and parents. Based on CBT, it integrates methods from Acceptance and Commitment Therapy (ACT), Dialectical Behavior Therapy (DBT), and Emotion-Focused Therapy (EFT). Focus areas include developing an understanding of the function and consequences of self-harm, as well as the role and impact of emotions in behavior.
A manual-based CBT intervention targeting adolescents (aged 12-17 years) with emotional difficulties consistent with anxiety and subclinical to mild depression, but not requiring treatment in specialized psychiatric care. The intervention begins with an assessment session and includes up to 14 sessions across 9 modules (6 core, 3 optional). Based on CBT, the intervention seeks to enhance the adolescent's understanding of how emotional experiences influence cognitive processes, physiological responses, and behavior. Methods include behavioral experiments, exposure, and emotion regulation strategies. The therapy is grounded in an individual case formulation, which identifies the maintaining factors of the young person's emotional difficulties and sets concrete goals for therapeutic work and change. Sessions involve the adolescent, parents, and relevant network members. Homework is assigned between sessions to support daily-life implementation.
A manual-based intervention for children and adolescents with subclinical signs of Attention Deficit Hyperactivity Disorder (ADHD). The intervention consists of four group sessions during 6-8 weeks, including parents/caregivers of up to eight children/adolescents, and is conducted by a STIME therapist from the child's local municipality. Individual sessions can be added when considered beneficial based on the family's needs. The intervention is based on family-based therapy and Vygotsky's Zone of Proximal Development and focuses on empowering parents to understand and address their child's behaviors. Between sessions, parents complete manual-structured homework and real-life practice at home. To reinforce progress and ensure consistency across the home and education settings, professionals from the child's educational setting or broader support network may also be involved
A manual-based intervention for children and adolescents (aged 5-17 years) with mild to moderate obsessive thoughts and compulsive behaviors, but not requiring treatment in specialized psychiatric care. The intervention begins with an assessment session and includes a minimum of eight sessions. Grounded in family-based cognitive behavioral therapy, it combines goal-focused work, psychoeducation, exposure, response, and prevention as the main therapeutic components. The primary aim is to support the child/adolescent in being exposed to situations that may trigger obsessive thoughts and to refrain from allowing these thoughts to dictate behavior. Sessions involve the child/adolescent and their parents. To support the process, it is possible to involve professionals from the learning environment and the child/adolescent's wider network. Homework assignments are given between sessions for both the child/adolescent and their parents, to support practice in daily life.
For the STIME-interventions 'Signs of Disordered Eating', 'Signs of Internalizing', 'Signs of Self-harm', and 'Take the control back', children and adolescents allocated to the control group will receive 3-4 individual online sessions with a psychologist over 10 weeks while waiting to start the intervention. The number of sessions depends on the presenting concern: up to three sessions for the interventions 'Signs of Internalizing', 'Signs of Self-harm', and 'Take the control back', and up to four sessions for the intervention 'Signs of Disordered Eating'. Sessions may involve the child/adolescent alone, the parents alone, or both together. Psychologists providing the sessions have experience working with all target groups, but have not received training in the STIME program. They will be given freedom to use less than the maximum number of sessions and to choose their therapeutic approach to mimic the variability of management as usual.
