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 semistructured 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.
