Abstract: This study reports on an initial examination of the construct validity of the Multidimensional Schizotypy Scale-Brief (MSS-B) and the first investigation of its psychometric properties outside of its derivation samples. The MSS-B contains 38 items that assess positive, negative, and disorganized schizotypy and has comparable content coverage and psychometric properties as the original 77-item Multidimensional Schizotypy Scale. Two large samples (n?=?1430 and 1289) completed the MSS-B, as well as measures of schizotypal personality traits and the Five-Factor Model of Personality. MSS-B scores were computed from the full-length scale in sample 1, whereas participants in sample 2 were administered the MSS-B. The psychometric properties and intercorrelations of the MSS-B subscales were consistent with findings from the original derivation samples, with no shrinkage in reliability. In terms of relations with schizotypal traits, the MSS-B positive schizotypy dimension had its strongest association with cognitive-perceptual schizotypal traits, MSS-B negative schizotypy had its strongest association with interpersonal schizotypal traits, and MSS-B disorganized schizotypy had its strongest association with disorganized schizotypal traits. The schizotypy dimensions were characterized by hypothesized patterns of distinct associations with the Five-Factor Model. The present findings are consistent with results from the full-scale MSS.
