Proponents of sensory integration therapy recommend application of deep pressure, induced by wearing a weighted vest, as an approach to treat perceptual processing disturbance in people with developmental disabilities. The present study evaluated the effects of wearing a weighted vest on stereotypy and attention to task of four children who had autism/pervasive developmental disorder. Behaviors were measured during 10-minute sessions under baseline (no vest), weighted vest, and vest without weight conditions. For all children, wearing the weighted vest did not reduce stereotypy or increase attention to task, and with three of them it appeared to have a negative influence. Clinical and research issues are discussed.
