Effectiviteit van Take it Personal!+, een behandeling voor problematisch middelengebruik bij mensen met een LVB

Individuals with mild intellectual disabilities or borderline intellectual functioning (MID-BIF) are at increased risk to develop a substance use disorder. Treatment programs are often not adapted to this target group. This study evaluated the effectiveness of Take it Personal!+, a personalized SUD treatment for individuals with MID-BIF. The treatment is based on motivational interviewing and cognitive behavioral therapy, supported by a mHealth application. Data were collected in a multiple baseline single-case experimental design with four phases: baseline, treatment, post-treatment and follow-up. Twelve participants were randomly allocated to baseline lengths varying between seven and eleven days. Substance use quantity was assessed during baseline, treatment and post-treatment with a daily survey using a mobile application, and substance use severity was assessed with standardized questionnaires. The results support the effectiveness of Take it Personal!+ in decreasing substance use in individuals with MID-BIF.
