An evaluation of strategies for training staff to implement the picture exchange communication system

The picture exchange communication system (PECS) is a functional communication system frequently used with individuals diagnosed with autism spectrum disorders who experience severe language delays (Frost & Bondy, 2002). Few empirical investigations have evaluated strategies for training direct care staff how to effectively implement PECS with clients. Using a multiple probe design, the current investigation evaluated staff training procedures for teaching three direct care staff to implement phases 1-3 of PECS for 3 adults with autism. Training with verbal instructions and an instructional video resulted in little improvement from pretest scores, underscoring the limited utility of workshops and instructional videos alone in teaching paraprofessional staff important clinical skills.
