Parent-Implemented Interventions for Young Children With Disabilities: A Review of Fidelity Features.

The purpose of this review was to analyze fidelity features in parent-implemented interventions for young children with disabilities. The authors conducted a review of 24 studies published in nine peer-reviewed journals. Each identified article was scored on the following categories: the participant characteristics, settings, study design, independent variables, measurement of implementation and intervention fidelity, parent training components, dependent variables, social validity, overall outcomes, and study rigor. The results indicated that, although all studies described parent training components, few reported implementation fidelity. Across the studies trainers were most likely to use performance-based feedback and modeling to support parent implementation of the intervention. Although 20 studies used single-case design methodologies, only 2 studies met contemporary single-case research design standards. The authors provide an analysis of implications for future research related to supporting high-fidelity implementation of parent-implemented interventions. [ABSTRACT FROM AUTHOR]
