Training Staff to Implement a Paired-stimulus Preference Assessment using Video Modeling with Voiceover Instruction

摘要

A key component of successful early intervention programming is the identification of stimuli that may function as reinforcers. One common direct method used by behavior analysts to determine preference is the paired-stimulus (PS) preference assessment. Although effective at identifying potential reinforcers, the PS procedure is only useful if staff are trained on the steps necessary to conduct the assessment. The current study examined the effectiveness of video modeling with voiceover instruction to train staff to conduct a PS preference assessment. Three staff were trained to do the following: (i) identify items to use during the PS assessment; (ii) conduct a PS preference assessment with a simulated consumer (i.e., an adult acting as a child); and (iii) score and interpret the results of the PS assessment. Generalization was assessed with an actual consumer (i.e., a child with an autism spectrum disorder). The results demonstrated that video modeling was effective, and staff demonstrated high levels of integrity up to 2months following training. These results support a growing body of literature supporting the use of video modeling as an approach to training. Copyright (c) 2015 John Wiley & Sons, Ltd.
