Journal of Intellectual Disabilities, Ahead of Print.
The aim of this review was to identify the type, content, and effectiveness of psychological parenting interventions for parents of children with intellectual disabilities to enhance child behavior and/or parental well-being. A systematic search yielded 21 studies involving 1825 participants. Studies were evaluated according to intervention content, pre- and post-treatment and follow-up effect sizes, and risk of bias. We categorized the interventions into those targeting ‘Child or interaction’ (child behavior, interaction and learning, understanding disability), and those targeting ‘Parent’ (parental well-being) or both themes. All these interventions had positive effects on parental well-being or child behavior. Parental outcomes were improved by interventions targeting ‘Parental well-being’, as well as ‘Child or interaction’. Child behavior showed improvements in programs focusing on ‘Child or interaction’, and in a mindfulness-based parental well-being program. During follow-up, most effects were sustained or further increased, but some studies showed no improvements over the control group.
