A randomized controlled trial of the effectiveness of Multisystemic Therapy in the Netherlands:Post-treatment changes and moderator effects

Objective: In the present randomized controlled trial, the effectiveness of multisystemic therapy (MST) in The Netherlands was examined. Moderator tests were conducted for ethnicity, age and gender. Methods: The sample consisted of N = 256 adolescents, referred because of conduct problems, and randomized to MST or treatment as usual (TAU). Assessments (questionnaires and observational ratings) took place before and immediately after the treatment. Results: MST was more effective than TAU in decreasing externalizing behavior, ODD, CD and property offences, but not for violence. Findings were mixed for adolescents’ and parental cognitions: the MST group, compared to TAU, showed an improvement in parental sense of competence, and a decrease in adolescents’ hostility, but no change in self-esteem and an increase in personal failure. MST was effective for positive dimensions of parenting and associations with prosocial peers, but not for relationships with deviant peers. MST was equally effective for adolescents of different ages and with different ethnicities. However, MST showed larger (and more positive) effects for adolescent cognitions for boys than for girls. Conclusions: Effects of MST in The Netherlands are generally comparable to the positive findings reported in American and Norwegian trials. MST seems equally effective across age and ethnic minority groups, but some gender moderator effects were found for adolescent cognitions

The Parent Participation Engagement Measure (PPEM): Reliability and Validity in Child and Adolescent Community Mental Health Services

Parent participation in community-based child mental health services is an important yet understudied process associated with treatment effectiveness. This paper describes the development and psychometrics of the Parent Participation Engagement Measure (PPEM) in a sample of 1374 parents and 563 youth receiving publicly-funded mental health services. Analyses indicated excellent internal consistency, and model fit indices/factor loadings supported a one-factor model. Convergent and discriminant validity were supported, although some coefficients were modest in magnitude. Psychometric results were consistent for Caucasian versus Hispanic, parent versus youth, and English versus Spanish-language respondents. The clinical and research utility of this measure are discussed
