Conditions
Summary
The goal of this observational study is to determine the effectiveness of a specialisation of multisystemic therapy (MST) for adolescents with severe behavioural problems from families with an intellectual disability (ID; MST-ID). To achieve this goal, a mixed method study design is used. To this end, a quantitative and a qualitatively primary research question are formulated: * Is MST-ID superior, when compared to standard MST, in reducing rule-breaking behaviour of adolescents (quantitative)? * What are the experiences of adolescents and/or parents receiving MST-ID treatment (qualitative)? Participants will be asked to complete two screeners (questionnaires delivered as a verbal interview) with a total duration of approximately 30 minutes. Other data will be collected through Routine Outcome Monitoring questionnaires that are part of standard MST procedures. To this end, five 'time points' have been identified: T0 (start of MST\[-ID\] treatment), T1 (end of MST\[-ID\] treatment), T2 (follow-up 6 month after MST\[-ID\] treatment), T3 (follow-up 12 month after MST\[-ID\] treatment), and T4 (follow-up 18 month after MST\[-ID\] treatment). The qualitative method used to gain insight into families' experiences is determined in consultation with the families. To assess the effectiveness of MST-ID, its treatment outcomes will be compared to standard MST treatment outcomes of families with ID.

Interventions
Multisystemic Therapy (MST) is an intensive, evidence-based treatment aimed at preventing out-of-home placement of adolescents with severe behavioural problems. The intervention is home-based and focuses not only on the adolescent, but also on the various systems surrounding the adolescent, such as the family, neighbourhood, school, and friends. MST helps parents increase their parenting competencies such as parental monitoring and find (more) social support in their environment. MST also helps adolescents improve their relationship with their parents, school participation, and social activities, and promotes contact with pro-social peers. These goals are achieved by working together with key figures in the family's environment. MST treatment duration is three to five months. In MST, a family can contact a therapist 24/7.
Multisystemic therapy - intellectual disabilities (MST-ID) is a specialisation of standard MST (see above), tailored to the needs and skill deficits of families in which the adolescent and/or parent(s) has/have a known or suspected ID. In MST-ID, among others, simplified language and visual support are used, and extra attention is paid to the generalisation of what has been learned in the treatment sessions.
