Utilizing physiological measures to facilitate phobia treatment with individuals with autism and intellectual disability: A case study

Despite the conceptualization of phobic fear as a multi‐factorial response, the measurement and treatment of phobias is often not comprehensive. The extant literature on the treatment of phobias for individuals with intellectual disabilities has exclusively focused on indices of behavioral avoidance. The present study demonstrates the treatment of behavioral avoidance and physiological reactivity in a child diagnosed with autism, intellectual disability, and a dog phobia. The results indicate that the individual often experienced physiological reactivity in the presence of the feared stimulus despite engaging in behavioral approach. Treatment of both behavioral avoidance and physiological reactivity resulted in successful generalization of treatment effects across three additional dogs and maintenance of treatment effects during a six‐month follow‐up assessment. Implications for examining multiple aspects of the anxious response when treating children with intellectual disabilities and severe language delays are discussed.
