目的美国耶鲁大学的前驱综合征结构化访谈（SIPS）是一种用于诊断精神病前驱综合征和测量前驱症状严重程度的方法。在这里，一个韩国版本的SIPS，其可靠性，有效性和因素结构进行检查，使用一个有代表性的韩国sample.Methods的韩国版本的SIPS管理到40名参与者在一个为期一年。然后评估SIPS的评分者间信度和内部一致性。此外，还利用主轴因子分析法对其因子结构进行了研究。结果40名被试中，12.5%的被试在1年的随访期内发生精神障碍。评价者间的可靠性是好的（类内相关=0.96），内部一致性是可以接受的（克朗巴赫的α =0.83）。三因素分辨率显示了最好的简单结构，占所有项目方差的52.6%。因子1和因子2分别与PANSS的阴性症状和认知功能障碍呈强相关。因子3与PANSS各因子均无相关性。结论韩国版SIPS量表是一种可靠的前驱症状评定工具，可用于前驱精神病的评定。精神病学调查2010;7：257-263
Objective The Structured Interview for Prodromal Syndrome (SIPS) from Yale University is intended to diagnose prodromal syndrome of psychosis and to measure the severity of prodromal symptoms. Here, a Korean version of SIPS is presented, and its reliability, validity, and factor structures are examined using a representative Korean sample.Methods The Korean version of SIPS was administered to 40 participants over a period of I year. The inter-rater reliability and internal consistency of the SIPS were then evaluated. In addition, its factor structure was investigated using principal-axis factor analysis. Concurrent validity was explored using Pearson correlation coefficients with the Positive and Negative Syndrome Scale (PANSS).Results Of the 40 subjects, 12.5% developed psychotic disorders during the 1-year follow-up period. Inter-rater reliability was good (intra-class correlations=0.96), and internal consistency was acceptable (Cronbach's alpha=0.83). A three-factor resolution displayed the best simple structure and accounted for 52.6% of all item variance. Factors 1 and 2 showed strong correlations with negative symptoms and cognitive dysfunction, respectively, on the PANSS. Factor 3 was not correlated with any factor on the PANSS.Conclusion The Korean version of SIPS is a reliable instrument for the assessment of prodromal symptoms in subjects and may be used to evaluate prodromal psychosis.
