摘要：

The Wisconsin Schizotypy Scales-the Perceptual Aberration, Magical Ideation, Physical Anhedonia, and Revised Social Anhedonia Scales-have been used extensively since their development in the 1970s and 1980s. Based on psychometric analyses using item response theory, the present work presents 15-item short forms of each scale. In addition to being briefer, the short forms omit items with high differential item functioning. Based on data from a sample of young adults (n = 1144), the short forms have strong internal consistency, and they mirror effects found for the longer scales. They thus appear to be a good option for researchers interested in the brief assessment of schizotypic traits. The items are listed in an Appendix A. (C) 2011 Elsevier Ltd. All rights reserved.
