Evaluating Multisystemic Therapy and MST-ID for Adolescents With Severe Behavioural Problems in Families With Intellectual Disabilities

What this Trial Is About

Researchers are evaluating a special type of multisystemic therapy called MST-ID for adolescents aged 10 to 19 with severe behavioural problems living in families affected by intellectual disability ID. The study compares MST-ID to standard multisystemic therapy MST to see if MST-ID is better at reducing rule-breaking and other behavioural issues. The study uses both numbers-based assessments and families personal experiences to understand treatment effects and is sponsored by De Viersprong. The treatments involved are intensive, home-based therapies with 3 to 5 home visits each week over about three to five months. Both MST and MST-ID target adolescents behavioural problems by involving their family, school, and social environments. MST-ID differs by adapting its approach to the needs of families with ID, using simpler language, more structured sessions, and extra practice time to help families apply what they learn. Families receive either standard MST or the MST-ID specialization following usual referrals. Participants complete questionnaires at five time points start of treatment, end of treatment, and three follow-ups at 6, 12, and 18 months after treatment. Data collection includes standard MST monitoring and special interviews or discussions to capture families experiences. Researchers measure rule-breaking behaviour, other behavioural problems, parenting stress, out-of-home placements, school or work status, addictions, social networks, parenting skills, family relations, social support, and adolescent success with peers and education or work. The study lasts over 18 months with ongoing assessments to track impact.
