Clinical translation of the ABA renewal model of treatment relapse

Abstract

ABSTRACTAn 18-year-old male’s attention-maintained problem behavior was treated with an alternative (ALT) variable-interval, variable-time (VI VT) schedule arrangement with two therapists each delivering attention at different rates in a multiple schedule of reinforcement. Despite the differing rates of VI VT attention, the procedures resulted in similar rates of problem behavior in the last three treatment sessions reducing problem behavior by an average of 45%. Following treatment, the two therapists conducted separate extinction sessions, initially in a different context until problem behavior extinguished and then returning to the original treatment context (i.e., the ABA renewal test). Extinction took 4.4 times longer in the renewal test for the therapist who implemented the high-rate VI VT treatment compared with the therapist who implemented the low-rate VI VT treatment. Although these results are preliminary, the implications for clinicians is that treatment designs that use low-rate treatment may be more effective than high-rate treatment in preventing relapse.
