Brief report: Effects of pressure vest usage on engagement and problem behaviors of a young child with developmental delays.

The purpose of this study was to examine the effects of wearing a pressure vest for a young boy with developmental delays. An A-B-A withdrawal design was used to examine the relation between wearing the pressure vest and child behaviors during a preschool art activity. Although the data showed moderate variability, no systematic differences were found in child engagement when the vest was worn and when the vest was not worn and problem behavior increased when the vest was being worn. These results are discussed in the context of the study limitations. Implications for future research are provided.
