The Wisconsin Schizotypy Scales (WSS) have been widely used in the study of clinical and non-clinical samples. However, researchers often find the length of the scales prohibitive. The present study examined the reliability and validity of recently developed 15-item short forms of the Perceptual Aberration, Magical Ideation, Physical Anhedonia, and Revised Social Anhedonia Scales in two large samples of non-clinically ascertained young adults. The scales demonstrated good reliability and correlated highly with the original scales. The validity of the scales was assessed by comparing the association of the original and shortened WSS with interview measures of psychotic-like and schizophrenia-spectrum symptoms and impaired functioning, as well as with questionnaire measures of personality and social impairment. The associations of the shortened WSS with the interview and questionnaire measures were comparable in terms of statistical significance and effect size with the associations of the original scales. The present findings provide the first demonstration of the validity of the shortened WSS and support their use in the study of schizotypy.
威斯康星分裂型量表（WSS）已被广泛应用于临床和非临床样本的研究。然而，研究人员通常会发现量表的长度令人望而却步。本研究在两个大型的非临床确定的年轻成年人样本中，检验了最近开发的感知偏差、神奇思维、身体快感缺失和修订的社交快感缺失量表的 15 项简短形式的可靠性和有效性。这些量表表现出良好的可靠性，并与原始量表高度相关。通过比较原始和缩短的 WSS 与访谈测量的类精神病和精神分裂症谱系症状和功能障碍，以及与人格和社会障碍的问卷测量的关联性，评估了量表的有效性。缩短的 WSS 与访谈和问卷测量的关联性在统计学意义和效应量方面与原始量表的关联性相当。本研究结果首次证明了缩短的 WSS 的有效性，并支持它们在分裂型研究中的应用。
