Screening for the schizotypal personality trait is one strategy to identify people who may be susceptible to early psychosis or be at high risk for prodromal psychosis. The Schizotypal Personality Questionnaire-Brief (SPQ-B) has been widely used to assess the schizotypal personality and has been translated into Chinese. However, the psychometric properties of the Chinese-version scale have yet to be evaluated.
This study evaluates the construct validity of the Chinese-version SPQ-B on a sample of male and female undergraduate students in Taiwan.
A cross-sectional design with convenient sampling was used for this study. The data were collected using the Chinese-version SPQ-B between October 2008 and June 2009. Participants included 513 male and 675 female undergraduate students in Taiwan. The factor construct validity of the scale was examined by confirmatory factor analysis using structural equation modeling with SPSS AMOS version 17 software.
The results show that the three-factor model fits the data better than the one-factor model for both male and female participants. The male participants scored significantly higher than their female counterparts in terms of total scale, interpersonal subscales, and disorganized subscales.
CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The Chinese version of the SPQ-B adequately achieves three-factor construct validity for undergraduate students. The scale may be used to screen for the schizotypal personality trait in both male and female college students to identify those at an elevated risk for mental illness.
对分裂型人格特质进行筛查是识别可能易患早期精神病或处于前驱精神病高风险人群的一种策略。简版分裂型人格问卷（SPQ-B）已被广泛用于评估分裂型人格，并且已被翻译成中文。然而，中文版量表的心理测量特性尚未得到评估。
本研究在台湾的本科男女学生样本中评估中文版SPQ-B的结构效度。
本研究采用方便抽样的横断面设计。在2008年10月至2009年6月期间使用中文版SPQ-B收集数据。参与者包括台湾的513名男本科学生和675名女本科学生。使用SPSS AMOS 17版软件通过结构方程模型的验证性因素分析来检验量表的因素结构效度。
结果表明，对于男性和女性参与者，三因素模型比单因素模型更能拟合数据。男性参与者在总量表、人际分量表和紊乱分量表上的得分显著高于女性参与者。
结论/对实践的启示：中文版SPQ-B在本科学生中充分实现了三因素结构效度。该量表可用于筛查男女大学生的分裂型人格特质，以识别那些精神疾病风险较高的人。
