Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Background of the study:

Over the years, a large body of research has shown that adolescents with intellectual disability are 3-4 times more likely to develop severe behaviour problems than adolescents without intellectual disability. Families in which adolescents and/or one or both parent(s) have an intellectual disability (from now on, families with ID) often deal with complex problems, putting the adolescent at an increased risk of out-of-home placement. Multisystemic therapy (MST) is an intensive home-based treatment, effective in reducing severe behaviour problems and preventing the out-of-home placement of adolescents. A specialisation of MST has been developed for families with ID: MST-ID. In MST-ID, among other alterations, simplified language and visual support is used, sessions are more structured and more time is scheduled for practicing exercises, and extra attention is paid to the generalisation of what has been learned in the sessions (with the aim of attaining long-term outcomes). Pilot studies show that when compared to standard MST, MST-ID shows similar or better treatment outcomes in families with adolescents with ID. Meanwhile, MST-ID has been disseminated more widely and the target population extended by including families in which only the parent(s) have an ID.

Objective of the study:

The aim of this study is to investigate the effectiveness of MST-ID for adolescents with severe behavioural problems from families with an intellectual disability (ID), compared to standard MST. It is hypothesised that MST-ID is more effective - in terms of fewer behavioural problems, more adolescents living at home, being in school/work, no new police contacts, less parenting stress - than standard MST. Treatment outcomes are considered both quantitatively and qualitatively.

Study design:

Quantitatively, the Propensity Score (PS) method is used to balance treatment groups and, combined with Multilevel Modelling (MLM), to estimate treatment effect over time. Qualitatively, the experiences of approximately 10 adolescents and/or parents are centralised. The qualitative research methods will be decided upon in a participatory manner with respondents (examples of potential research methods are interviews, focus group discussions, or photo elicitation).

Study population:

Adolescents (10-19y) with severe behavioural problems or delinquent behaviours, and their parent(s) receiving MST(-ID) treatment. All research participants must be from families where either the adolescent and/or parent(s) has/have ID.

Intervention:

Following standard referral procedures, families were either referred to standard MST or MST-ID treatment (i.e., non-randomly). Both standard MST and MST-ID are intensive, home-based treatments with 3-5 home visits per week, targeting the severe behavioural problems of adolescents across multiple life domains. MST-ID is tailored to the needs and skill deficits of adolescents and/or parents with ID. Concretely, more attention is paid to how therapists create engagement, implement interventions, and realise support from informal supports, in a tailored, developmentally appropriate, and simplified manner (meaning in a more structured way and using accessible language, among others), when compared to standard MST.

Research questions:

Building on the objectives, the following research questions were formulated:

Primary research questions:

1. Is MST-ID superior, when compared to standard MST, in reducing rule-breaking behaviour of adolescents, according to parents?
2. Is MST-ID superior, when compared to standard MST, in reducing rule-breaking behaviour of adolescents, according to adolescents?

Secondary research questions:
3. Is MST-ID superior, when compared to standard MST, in reducing externalising and internalising behavioural problems of adolescents, according to parents?
4. Is MST-ID superior, when compared to standard MST, in reducing externalising and internalising behavioural problems of adolescents, according to adolescents?
5. Is MST-ID superior, when compared to standard MST, in reducing parenting stress?
6. Is MST-ID superior, when compared to standard MST, in preventing short and long term out-of-home placement, delinquency, truancy or joblessness, and addictions of adolescents?
7. Is MST-ID superior, when compared to standard MST, in realising improvements on family's social networks?
8. Is MST-ID superior, when compared to standard MST, in improving the instrumental outcome parenting skills?
9. Is MST-ID superior, when compared to standard MST, in improving the instrumental outcome family relations?
10. Is MST-ID superior, when compared to standard MST, in improving the instrumental outcome social support?
11. Is MST-ID superior, when compared to standard MST, in improving the instrumental outcome adolescent success in an educational or vocational setting?
12. Is MST-ID superior, when compared to standard MST, in improving the instrumental outcome adolescent involvement with pro-social peers?
13. Is MST-ID superior, when compared to standard MST, in improving the instrumental outcome change in adolescent problem behaviour?
14. What are the experiences of adolescents and/or parents receiving MST-ID treatment?
15. Do effects across subgroups of adolescents and/or parents with ID differ?

MST-ID is expected to be superior in achieving the aforementioned outcomes (#1-13) when compared to standard MST. Research questions #14-15 will be assessed exploratively, therefore no hypotheses have been formulated.

Multisystemic therapy

Intervention Type BEHAVIORAL

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

Intervention Type BEHAVIORAL

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.
