Operant extinction in the treatment of severe maladaptive behavior: adapting research to practice.

Operant extinction involves termination of reinforcement for a previously reinforced response. As a clinical intervention for severe maladaptive behavior operant extinction is often repudiated because of intensity of side effects, length of treatment time required, and implementation difficulties. This article discusses both theoretical and practical aspects of extinction, including components of the extinction process and the importance of functional assessment to its effective use. Potential strategies for increasing the effectiveness of extinction while diminishing intrusiveness are recommended. Based on recent research innovations, a technology is emerging for effective use of operant extinction in the treatment of severe maladaptive behavior.
