About this study

Official title: Is Mentalization-based Therapy More Effective for Adolescents With Disruptive and Dissocial Disorders Than TAU-plus (Emotion-focused Parent Training With Supportive Child Psychiatric Care)?

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.

Read the detailed description

The study includes adolescents between the ages 12 to 19 of any gender who have been diagnosed with Oppositional defiant or Conduct-dissocial disorder (serious problems with following rules or criminal behavior).

The diagnosis is the primary outcome, which is assessed based on a diagnostic interview. Secondary outcomes include antisocial behavior, quality of life, symptom burden, and personality functioning (measured through self-report questionnaires), as well as aggressive behavior (measured through interview).

During the study, there will be monthly process assessments. In these assessments, participants will be asked questions about mentalizing, emotion regulation, therapy experience, antisocial behavior, and how much they trust others. These variables are considered mediators of changes in outcome.

Participants will also be interviewed regarding personality functioning to investigate whether dissocial disorders are related to personality disorders.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Mentalization-Based Therapy (MBT)Behavioural

    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.

  • Treatment-as-usual-plus (TAU-plus)Behavioural

    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.

Study groups in NCT07181928
Study groupRoleWhat they receive
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.
Receives: Behavioral: Mentalization-Based Therapy (MBT)
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.
Receives: Behavioral: Treatment-as-usual-plus (TAU-plus)

What is being measured

The primary outcome is the main question the study is designed to answer.

  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).

    Measured: Day 0, Month 14

Secondary outcomes (7)
  1. Aggressive behavior assessed with the german "Modified Overt Aggression Scale" (MOAS-D)

    Score range: 0 - 300, with higher score representing higher value of aggressive behavior

    Measured: day 0, month 11 month 14

  2. Social aggression assessed with the subscale from Subtypes of Antisocial Behavior Questionnaire (STAB)

    Score range 11 - 55, with higher score representing higher value of Social aggression

    Measured: day 0 month 11 and month 14

  3. Quality of life assessed with the Kidscreen 10 Index

    Score range: 10-50, with higher scores representing better quality of life

    Measured: day 0, month 11, month 14

  4. Symptom burden assessed with the Strengths and Difficulties Questionnaire (SDQ)

    Score range: 0 - 40, with higher score representing higher value of difficulties or strengths respectively

    Measured: day 0, month 11, month 14

  5. Participation assessed with the mini self-rating for psychological activities and participation (Mini-ICF-APP)

    Score range: 0 - 7, with higher score represeting higher value of overall capacity level

    Measured: day 0, month 14

  6. Gender typicality assessed with the "Instrument zur Erfassung des Geschlechtsrollen-Selbstkonzepts im Jugendalter" (GRI-JUG)

    There are four subscales - femenine positive and negative and Masculine positive and negative. Score range for each subscale: 1-5, with high scores indicate a high expression of the respective facet of the gender role self-concept.

    Measured: day 0, month 14

  7. Personality functioning assessed with the Level of Personality Functioning Brief Form (LPFS-BF)

    Score range: 12-48, with higher score representing higher value of personality pathology

    Measured: day 0, month 11, month 14
