Abstract
Social skills deficits are a defining feature of individuals diagnosed with autism and other pervasive developmental disorders (PDD), which can impair functioning and put the individual at higher risk for developing problem behavior (e.g., self-injury, aggression). In the current study, an adolescent with PDD displayed inappropriate social behavior (inappropriate comments, social withdrawal, and touching others without their permission) during social interactions. An intervention using instructions, differential reinforcement, and corrective feedback successfully reduced inappropriate social behaviors.
