Examining the use of deep touch pressure to improve the educational performance of students with disabilities: A meta-analysis

Abstract

The current meta-analysis examined the use of deep touch pressure (DTP; e.g., weighted vests) with students with disabilities. DTP is a form of sensory integration therapy that is currently used extensively in schools with students with autism and other disabilities. Each study in the analysis was evaluated using the Council for Exceptional Children's guidelines for evidence-based practices. In addition, noting the debate regarding appropriate single-case effect sizes, the current study calculated omnibus effect sizes utilizing a variety of single-case design effect sizes. Results of the current study suggest that DTP interventions are of generally poor quality and demonstrate effects that do not validate their current use for students with disabilities.
