Effects of Behavioral Skills Training on Implementation and Generalization of the Picture Exchange Communication System (PECS): a Systematic Replication

Abstract

The effectiveness of a behavioral skills training (BST) package, which included verbal and written instructions, modeling and role-play with a confederate learner, and feedback was used to teach the implementation of Phases 1 --3A of the picture exchange communication system (PECS). The BST package was implemented using a multiple baseline design across three instructional staff at a center that provides services to children with autism. All participants had minimal or no previous training in PECS. Results indicate the BST package was effective in teaching these skills to all participants in a minimal amount of time, and that the results of training generalized to the classroom environment with students to whom the teachers were assigned to work with on a daily basis. Results are discussed with respect to the effectiveness and efficiency of the training package; and implications for future trainings for individuals who work with children with limited functional communication skills.
