The effectiveness of the peak relational training system and corresponding changes on the VB‐MAPP for young adults with autism

Abstract

The current investigation sought to extend prior research evaluating the use of the PEAK Relational Training System as a comprehensive treatment model in improving language skills demonstrated by individuals with autism. Baseline PEAK-Direct Training and Verbal Behavior Milestone Assessment and Placement Program (VB-MAPP) assessments were conducted across 3 adult male participants, and scores on the PEAK-Direct Training assessment were used to select targets for intervention. Language instruction guided by the PEAK-Direct Training module was implemented for 45 to 69 days across participants. Results suggest that participants mastered target skills throughout the training phase, and VB-MAPP test probes showed an increasing trend. Follow-up probes suggested that scores on the VB-MAPP maintained when training was discontinued. In addition, participants demonstrated an increase in assessment scores on the PEAK-Direct Training assessment in the follow-up phase, including the mastery of untargeted verbal skills.

Relating different perspectives on how outcomes of behavior influence behavior

“…Although RFT has given rise to useful analyses and interventions (e.g., Dixon et al, 2018; Hayes et al, 1999), much conceptual, translational, and empirical work still needs to be done (e.g., Barnes‐Holmes et al, 2016; Barnes‐Holmes & Harte, 2022). Whereas traditional functional approaches rest on concepts that have been induced across many empirical studies (e.g., reinforcement, punishment), rule‐governed behavior and AARR are still less well examined.…”
