This study evaluated the use of a peer video modeling and prompting intervention used to teach three adults with autism to give a specified verbal and physical response when greeted. This intervention used a six-step task analysis to verify correct completion of the target behavior. At baseline, each of the three participants gave little to no response when greeted but after the video modeling and prompting intervention all three had acquired at least five out of six (83%) of the target behavior steps. Follow-up probes demonstrated that all three of the participants had maintained at least 4 out of 6 (67%) of the targeted steps weeks after the intervention phase had finished. These data suggest that using peer video modeling and prompting to teach social skills to adults with autism can be an effective educational intervention.

Video self-modeling has been found to be effective in increasing appropriate behaviors, increasing task fluency, and decreasing inappropriate behaviors. During video self-modeling, a student is filmed completing a task and then mistakes, prompts, and negative behaviors are edited from the video. When the edited video is viewed by the subject student, the student views a perfect model of him or herself successfully completing the given task. Video self-modeling has been used predominately with participants with autism spectrum disorder. This study is a replication of a previous study in which the effectiveness of video self-modeling and video peer modeling was compared (Sherer, Paredes, Kisacky, Ingersoll, & Schreiman, 2001). Sherer et al. evaluated these procedures with high functioning students with autism using a combined multiple baseline across participants and alternating treatment design. This study differs from Sherer et al.'s study in its use of participants who have multiple disabilities and low cognitive functioning. The results show that video self-modeling is effective for some participants while video peer modeling is effective for others. The individual student's preference for one form of video modeling over another form may indicate the method that is best for a particular participant. Implications for further research are included.
