This article reports on the development and psychometric properties of a brief version of the Multidimensional Schizotypy Scale (MSS-B). The MSS-B contains 38 items that assess positive, negative, and disorganized schizotypy. The scale was derived from the full-length Multidimensional Schizotypy Scale, and the positive, negative, and disorganized subscales were designed to provide the same content coverage as the original subscales. Scale development involved a derivation sample (n = 6265) and a separate cross-validation sample (n = 1000), both drawn from four universities and Amazon Mechanical Turk. The MSS-B was derived using classical test theory, item response theory, and differential item functioning. The three subscales exhibited high internal-consistency reliability, good item- and model-fit, good test information functions, and expected patterns of intercorrelations and associations with neuroticism, sex, and race/ethnicity. This pattern of findings was almost identical between the derivation and cross-validation samples. Furthermore, the pattern of findings was closely comparable for MSS-B subscales and the full-length MSS subscales. The MSS-B appears to offer a promising brief measure for assessing schizotypy.
