A modern behavioral perspective on child conduct disorder: integrating behavioral momentum and matching theory.

It has been suggested that knowledge produced within the operant laboratory is of little or no use to clinicians. I argue, on the contrary, that laboratory science has provided clinicians with two general principles that may expand the focus of behavioral family therapy to incorporate a wide range of clinical interventions that have heretofore been considered nonbehavioral. These principles, matching theory and behavioral momentum, outline the relativity of reinforcement and the persistence of behavior in the absence of reinforcement, respectively. These principles make specific predictions concerning clinical interventions aimed not only at identified reinforcement contingencies, but also the context within which reinforcement contingencies are operative. This expanded behavioral formulation allows both the clinician and the researcher a framework for designing, implementing, and assessing techniques that target cognition, affect, and interpersonal relationships, as well as specific behaviors.
