Abstract
The enhanced-choice model (ECM; Rajaraman et al., 2021) has been hypothesized as one way to promote assent in behavior analytic practices. Previous studies have used ECM within skills-based treatment packages (Metras et al., 2023; Rajaraman et al., 2021; Staubitz et al., 2022) and replicated effectiveness in reducing target behavior and increasing task completion amongst participants. This study evaluates the effectiveness of ECM within a differential reinforcement of alternative (DRA) behavior treatment package to reduce target behavior and increase task completion. One participant was included with autism spectrum disorder, minimal vocal-verbal abilities, and engaged in aggression and disruption. Results demonstrate that ECM was effective at reducing target behavior but ineffective at increasing task completion and allocating to majority of time spent in treatment. Study outcomes are indicative of requiring further research in evaluating ECM in other treatment packages, such as DRA. Limitations of this study and future research opportunities are discussed.
