The clinical utility of a behavior modification procedure, Differential Reinforcement of Other Behavior, to reduce resistive behavior during physical therapy was investigated using a sample of four severely physically and developmentally disabled females. A multiple baseline design across subjects was employed to assess the effects of positively reinforcing behaviors other than the resistive or inappropriate behaviors during the therapy sessions. The procedure employed produced a dramatic decrease in the inappropriate behavior of two subjects, a moderate decrease in the behavior of one subject, and a minimal decrease in the fourth. The observational system generated extremely reliable data as indicated by the high degree of interobserver agreement.
