A Meta-Analysis of Intervention Effects on Challenging Behaviour among Persons with Intellectual Disabilities

Journal of Intellectual Disability Research, v54 n7 p634-649 Jul 2010
Background: Persons with intellectual disabilities (ID) often show challenging behaviour. We review distinct interventions that are applied to treat these challenging behaviours, and analyse intervention effects and moderating variables. Methods: A literature search was conducted using the databases "ERIC," "PsycINFO," "Web of Science" and "Medline." A random-effects meta-analysis was carried out, supplemented with sensitivity, subgroup, meta-regression and publication bias analyses. Results: Eighty potential articles were identified, from which 30 contained sufficient data to enable statistical meta-analysis. From these 30 studies, 18 described a biological, 13 a psychotherapeutic and nine a contextual intervention, either applied alone or combined. The overall standardised mean difference was 0.671 (SD = 0.051). As shown by sensitivity analysis, this summary effect size is robust. Assessed through subgroup and meta-regression analysis, all tested moderators showed no statistically significant association with the treatment effects. After applying a funnel plot-, a fail-safe N-, and Duval's and Tweedie's trim and fill-analysis, we conclude that our meta-analysis does not suffer much from publication bias effects. Conclusions: Several biological, psychotherapeutic and contextual interventions effectively reduce challenging behaviours among persons with ID.
