Brief Summary
The goal of this clinical trial is to investigate if Mentalization-based therapy (MBT) is superior to enhanced usual care (treatment-as-usual-plus (TAU-plus)) for adolescents with disruptive behavior or dissocial disorders. MBT is an intervention that aims to improve mentalizing. Mentalizing is the ability to reflect on mental states in oneself and others that motivate behavior. TAU-plus consists of psychiatric care for the adolescent, along with additional emotion-focused skills training for the parents. Participants will be randomized in one of two groups using one study center.

Outcome Measures
Primary Outcomes (1)
Remission rate based on diagnostic criteria for Disruptive behavior or Dissocial disorders
Remission is defined as the proportion of participants no longer meeting full diagnostic criteria for Conduct-dissocial disorder (CDD) or Oppositional defiant disorder (ODD). CDD is assessed with the "Diagnostisches Interview bei psychischen Störungen - Version für Jugendlichen" (J-DIPS) and ODD with the "Diagnostisches Interview bei psychischen Störungen im Kindes- und Jugendalter" (K-DIPS).

Study Arms (2)
Mentalization-Based Therapy (MBT)
EXPERIMENTAL45 adolescents diagnosed with conduct disorder/oppositional defiant disorder will receive MBT over 10 months. The patients have 30 individual sessions weekly conducted by one therapist with formal training in MBT. Additionally, the patient receives 5 sessions together with the parents and the parents will have another 5 sessions without the patient.
Treatment-as-usual-plus (TAU-plus)
ACTIVE COMPARATOR45 adolescents diagnosed with conduct disorder/oppositional defiant disorder will receive standard psychiatric care over 10 months and their parents will participate in the Emotion Focused Skills Training (EFST). The patient receives individual psychiatric sessions at least two per quarter depending on the adolescent's needs. The individual sessions are conducted by a child and adolescent psychiatrist and/or by a therapist working under their supervision. EFST includes an intake session, 5 two-hour group sessions (6-12 parents, led by two therapists), and a final individual session.
Interventions
MBT is a manualized psychodynamic therapy based on attachment theory, designed to restore adolescents' mentalizing in general and in emotionally stressful situations and relationships. It targets to rebuilt epistemic trust, to successfully mentalize oneself and others.
The adolescents receive supportive child psychiatric consultations. For the parents the EFST sessions combine mindfulness, theoretical input, and experiential practice. Parents learn and apply four core skills: validation, repair, motivation, and setting boundaries.
