Here we present a protocol for administration of the video-referenced rating of reciprocal social behavior (vrRSB) using a paper or online version. This survey quantifies RSB, a prerequisite for social competence, in toddlers through "video-referenced" items whereby a subject is compared to a reference child shown in a three-minute video.
