ABSTRACT
When it is determined that simple activation has failed due to a lack of environmental support the BA clinician turns to contingency management procedures. Contingency management procedures traditionally have been de®ned as very systematic, supervised interventions that control the delivery of consequences following easily measurable target outcomes (e.g., weight loss, abstinence from alcohol). Although consequences provided in these programs are often quite arbitrary (e.g., money provided for drug abstinence), they have the advantage of establishing competing contingencies to work against entrenched problem behaviors and have been found to be quite effective (e.g., Melin, Andersson, & GoÈtestam, 1976).
