THE EFFECT OF CONTINGENT REINFORCEMENT ON TARGET VARIABLES IN OUTPATIENT PSYCHOTHERAPY FOR DEPRESSION: A SUCCESSFUL AND UNSUCCESSFUL CASE USING FUNCTIONAL ANALYTIC PSYCHOTHERAPY

Abstract

The current study investigated a behavior‐analytic treatment, functional analytic psychotherapy (FAP), for outpatient depression utilizing two single‐subject A/A+B designs. The baseline condition was cognitive behavioral therapy. Results demonstrated treatment success in 1 client after the addition of FAP and treatment failure in the 2nd. This study highlights the challenges in measuring treatment progress and outcome idiographically in this population.
