Abstract

Technological advances have allowed professionals to obtain extended recordings of caregiver–client interactions in natural settings, but scoring recorded video at normal speed to identify instances of low-rate problem behavior is impractical in terms of scoring time. Fast forwarding is a continuous measurement system in which all seconds of an observation are viewed at a speed faster than normal. In Study 1, we evaluated whether three groups of five observers could discriminate problem behavior at three fast-forwarding speeds across 10-min observations. We analyzed the efficiency of using fast forwarding compared to continuous scoring, and interobserver agreement across the fast-forwarding speeds. In Study 2, we compared the accuracy, efficiency, and social acceptability of fast forwarding (3.5x) and momentary time sampling (3.5 s) across 90-min observations. Results support the use of 3.5x fast forwarding as a viable measurement system of improving the practicality of scoring problem behavior from video.
