Clinical Safety and Treatment of Severe Aggression: Behavioral-Pharmacological Intervention Evaluation in a Young Adult With Autism Spectrum Disorder

This case study concerned clinical safety and behavioral-pharmacological intervention with an 18-year-old man who had autism spectrum disorder and high-frequency aggression toward care providers at a specialized school. A multicomponent behavior support plan included antecedent, differential reinforcement, environmental modification, and physical management procedures subsequently combined with psychotropic medication (aripiprazole). Clinical safety components emphasized comprehensive care provider training, continuous supervision, function-based treatment, and prevention-focused strategies. The behavioral-pharmacological intervention eliminated implementation of aggression-contingent physical restraint and was associated with increased transition compliance during the school day. Throughout the 7.5 months duration of the study, there were no injuries to the participant or other students and a single injury was sustained by one care provider. Intervention effects were long-standing, and care providers rated their training, implementation fidelity, and therapeutic outcome favorably.

Functional Communication Training and Most-To-Least Prompting as Treatments for Problem Behavior

Functional communication training (FCT) is a treatment for problem behavior in which the learner is taught a communicative behavior that fulfills the same function as the problem behavior. Although effective, when FCT is used to request breaks from work, limitations include increased time spent in breaks and reduced task-related responding. An alternative treatment is most-to-least prompting (MTL) of a task in which a therapist provides the most helpful prompts for task-related responding (e.g., physical guidance) and gradually reduces the amount of help (e.g., visual prompt and then verbal) until the learner responds independently. We evaluated FCT and MTL in a multiple treatments design with an 11-year-old girl with severe developmental disabilities. Both treatments reduced problem behavior from baseline levels, and academic responding was greater during MTL than during FCT. MTL is an errorless teaching approach conceptualized as an abolishing operation that reduces the aversiveness of a task and makes escape less valuable.
