Training frontline staff to respond to and manage challenging behaviors of individuals with autism spectrum disorder (ASD) poses a pervasive problem in the delivery of treatment services. Traditional synchronous staff training methods are expensive, time-consuming, and often do not result in high treatment integrity. Video Modeling alternative to traditional staff training and is an efficient, effective, and cost-effective. This study examines the use of technology-based antecedent training, and asynchronous Video Modeling (VM), on frontline staff's implementation of behavior intervention strategies. The current study extends the literature by presenting one behavior intervention strategy per video model to assess the acquisition and maintenance of discrete steps in a behavior intervention strategy. Additionally, the study evaluates the effect of video modeling as a training modality on client challenging behaviors, a dependent variable that is not typically measured in video modeling studies.
