Multiple baseline study investigated to what extent individuals with autism would learn to operate a speech generating device (SGD) to request a preferred object by observing a video model. Participants were two males with autism, cognitive disability, and speech impairment, aged 17 and 21 years respectively. The intervention consisted of each participant viewing a 10 to 15 second video model that demonstrated the requesting of a preferred object using an SGD. Baseline, intervention, and generalization were all implemented within a special education classroom in a public school. Following conclusion of data collection, a survey gauging the social validity of the study was distributed to instructional staff who knew the students. After viewing the video model, both participants displayed the ability to request preferred items using the SGD without prompting or cues. However, participants did not generalize requesting using the SGD to a second preferred object. Survey results indicated that respondents considered appropriate requesting was important; furthermore, the use of video modeling for instructions was strongly supported by the staff, as was the use of an SGD. Study limitations and implications for future research are discussed.
