The influence of observations and ratings on implementation of discrete trial instruction

Children diagnosed with autism spectrum disorder are often taught using discrete trial instruction. Because of low trainer-to-staff ratios commonly found in human service settings, research is needed to find an efficient method to train staff to implement discrete trial instruction with little to no in-vivo training by a qualified trainer. One such technique is observing and rating the behavior of another individual. The resulting improvement in the observer's own behavior is referred to as the observer effect. The purpose of the present study was to assess the effects of conducting behavioral observations and ratings on staff implementation of discrete trial instruction. Staff trainees viewed videos of the implementation of each step, rated the accuracy of implementation, and conducted the procedure with a confederate consumer. The procedure was effective, and the effects extended to novel skills.
