Description: Background. There is limited research validating the use of weighted vests for problem behaviours/social attention in toddlers with autism spectrum disorders (ASD) although vests are commonly used in early intervention to improve attention. Purpose. The effect of weighted vests on competing behaviours and joint attention (a pivotal skill for development and a core deficit for toddlers with ASD) in semi-structured play with their mothers was investigated. Methods. A multiple baseline design that included generalization probes to provide evidence of treatment effects across adult female play partners. Unambiguous definitions were created for competing behaviours and joint attention resulting in good inter-observer reliability. Mothers' morale was measured pre- and post-intervention. Findings. There were no replicated effects of vests on competing behaviours or joint attention. Mothers experienced increased morale in spite of null effects of the intervention. Implications. The findings suggest needed re-evaluation of the use of weighted vests with toddlers. [PUBLICATION ABSTRACT]
