Dog phobias are common in individuals with autism; however, evidence supporting behavioral interventions is limited. The current study evaluated the efficacy of contact desensitization plus reinforcement on dog phobic behavior exhibited by three children diagnosed with autism. The treatment package improved contact with dogs in analog and naturalistic settings and the improvements were maintained at follow-up and in generalization tests. Parents/caregivers also provided high consumer satisfaction reports.Approximately 30 % of individuals diagnosed with autism also receive a comorbid diagnosis of a clinical phobia.Research has shown that behavioral treatment for dog phobias in individuals with intellectual disabilities is contact desensitization plus reinforcement using two hierarchies: size of the dog and distance to the dog; no escape extinction was necessary.The current systematic replication shows that this treatment package was effective for children with autism using only a single hierarchy composed of distance to the dog.Future practitioners may wish to examine whether this treatment package also produces changes in supplemental physiological measures such as pupil dilation, heart rate, galvanic skin responses, and respiration.
