A further evaluation of behavioral skills training for implementation of the picture exchange communication system


  • This project constituted the master's thesis completed by the first author under the supervision of the second author to fulfill graduation requirements for the Applied Behavior Analysis program at Youngstown State University. We thank Cecelia Maderitz and Vilmary Placeres for their assistance with data collection.


We evaluated the effectiveness of a behavioral skills training package to teach implementation of Phases 1, 2, and 3A of the picture exchange communication system (PECS) to teachers employed at a therapeutic center for children with autism. Probes in the natural environment and follow-up were conducted with children who were assigned to work with the teachers in their own classrooms. Results provide additional support for the efficacy of behavioral skills training to teach implementation of PECS.
