| Abstract: | Objectives: This meta‐analysis examined the effectiveness of psychosocial interventions for youth with mild intellectual disabilities or borderline intellectual functioning (MID‐BIF) and externalising problems. Methods: We assessed 2221 studies for eligibility and included seven studies containing 14 effect sizes. We used a multilevel modelling approach to analyse the data and calculated two different types of effect sizes: one for controlled trials and one for intervention pre‐test to post‐test effects (across all studies). Results: Both controlled trial effect sizes (g = 0.49) and pre‐test to post‐test effect sizes were significant (g = 0.53). We were unable to detect heterogeneity of effects because of the small number of eligible studies. The risk of bias was generally high. Discussion: Results suggest that psychosocial interventions decrease externalising problems among youth with MID‐BIF. Effect sizes appear similar to those for youth without MID‐BIF. We discuss recommendations for how the field can move forward. [ABSTRACT FROM AUTHOR] |
