The purpose of the current study was to evaluate the effectiveness of whether Behavioral Skills Training (BST) was effective in teaching PEAK-DT to parents of children with Autism Spectrum Disorder (ASD). Along with, if parent implementation of PEAK was effective in increasing the children’s PEAK scores. Three parents and their child with autism were participants in the current study using the PEAK Relational Training System-Direct Training module (PEAK-DT). The procedure first required the parents to read information on how to implement the programs found in the introduction of the PEAK-DT module. Following this step, parents observed their child’s therapy sessions conducted at an ABA clinic by student therapists. Next, the parents were instructed to implement three programs and received feedback from the child’s therapist. Implementation fidelity was collected based on the parent performance and child progress was recorded based on percent correct responding within the actual program. Each parent was able to successfully implement programs within the PEAK-DT module within their child’s therapy sessions and the children were accurately responding and two of the three children had increases in skill acquisition. The results of the present study suggest that training parents using a BST model to implement PEAK-DT was effective in teaching children with autism.
