Previous research has demonstrated the effectiveness of treatments with and without escape extinction to treat escape-maintained behavior. The aim of this study was to evaluate the use of differential positive reinforcement (DPR) without escape extinction (EE) for escape-maintained behavior in the home setting. Differential positive reinforcement is an effective function-based procedure known to produce reductions in problem behavior maintained by escape. Two subjects with autism spectrum disorder were included in this study. A functional analysis was conducted to confirm escape as the variable maintaining problem behavior for both subjects. Differential positive reinforcement without EE was evaluated using a reversal design. Results showed DPR without EE was effective in reducing problem behavior to near-zero levels for both subjects. This study demonstrated the use of an effective procedure to reduce problem behavior maintained by escape in the home setting without the use of EE.
