Expert and Target Scoring: Their realtion, corresponding test instructions, and their effect on construct validity of video-based social understanding test (VSU)

This study investigated the relation between expert and target scoring of a video-based social understanding test (VSU) under two different types of instructions (internal and observer). The effects of the scoring methods and instructions on the VSU's construct validity were also examined. A total of 529 pilot applicants completed the VSU (some with internal and some with observer instructions), cognitive ability and knowledge tests, and a personality questionnaire. A subsample (n = 132) completed the VSU again with the other instructions and participated in an assessment center (AC). The two scores were moderately correlated; correlations decreased when the instructions were considered. Neither expert nor target scores showed convergent validity with AC variables; none of the scoring-instruction combinations showed significant associations with the remaining measures
