Group contingencies targeting inappropriate behavior may be especially useful in residential settings where the staff to client ratio makes individualized behavior plan implementation difficult. The purpose of the current study was to evaluate an independent group contingency on inappropriate behavior in a secure residential facility for offenders with disabilities. The independent group contingency involved differential reinforcement of low rate and differential reinforcement of other behavior via access to a special activity (a catered weekly lunch). The group contingency was alternated with non-activity weeks for a total of 48 weeks. Results were analyzed across and within residents and showed lower overall rates of inappropriate behavior on activity weeks than non-activity weeks for the majority of residents.
