The Reliability and Validity of the Thin Slice Technique: Observational Research on Video Recorded Medical Interactions

Introduction: Observational research using the thin slice technique has been routinely incorporated in observational research methods, however there is limited evidence supporting use of this technique compared to full interaction coding. The purpose of this study was to determine if this technique could be reliability coded, if ratings are consistent between the first, second and third slice, and if they are indeed representative of full interactions.

Methods: Three 30-second thin slices were sampled from the beginning, middle and end of a full-length video-recorded …
