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.
The Korean version of SIPS was administered to 40 participants over a period of 1 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).
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.
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.
耶鲁大学的前驱综合征结构性访谈（SIPS）旨在诊断精神病前驱综合征，并测量前驱症状的严重程度。在这里，我们呈现了 SIPS 的韩文版本，并使用具有代表性的韩国样本，对其信度、效度和因子结构进行了检验。
在 1 年的时间里，对 40 名参与者进行了韩文版 SIPS 的测试。然后，评估了 SIPS 的组内信度和内部一致性。此外，使用主成分因子分析探讨了其因子结构。使用与阳性和阴性症状量表（PANSS）的 Pearson 相关系数来探讨其同时效度。
在 40 名受试者中，有 12.5%在 1 年的随访期间发展为精神病障碍。组内信度良好（组内相关系数=0.96），内部一致性可接受（Cronbach's alpha=0.83）。三因子分辨率显示出最佳的简单结构，占所有项目方差的 52.6%。因子 1 和 2 与 PANSS 的阴性症状和认知功能障碍分别呈强相关，而因子 3 与 PANSS 上的任何因子均无相关性。
韩文版 SIPS 是评估前驱症状的可靠工具，可用于评估前驱期精神病。
