Although the comprehensive assessment of at-risk mental states (CAARMS) is one of the most widely used instruments for identifying individuals meeting the criteria for ultra-high risk (UHR) of developing psychosis, the psychometric properties of the Korean version of the CAARMS (CAARMS-K) have not been studied to date. Thus, we tested the reliability, validity, and factor structure of the CAARMS-K in a Korean population.
The CAARMS-K was administered to 96 UHR individuals. The inter-rater reliability and internal consistency of the CAARMS-K were evaluated. In addition, its factor structure was investigated using principal-axis factor analysis. Concurrent validity was examined by comparing the extracted CAARMS-K factors with the five factors of the positive and negative syndrome scale (PANSS) using Spearman's correlation tests. The percentage of transition to psychosis was examined at 1- and 2-year.
The inter-rater reliability was good (intraclass correlation = .89), and the internal consistency was acceptable (Cronbach's alpha = .812). A five-factor solution demonstrated the best simple structure and accounted for 43.1% of all-item variance. The five factors extracted from the factor analysis were similar to the PANSS five factors and significantly correlated with the factors of the PANSS. Among the 96 UHR individuals, 11 (11.5%) and 17 (17.7%) developed psychotic disorders during the 1- and 2-year follow-up, respectively.
The CAARMS-K is a reliable and valid instrument for the assessment of UHR individuals in Korea.
尽管综合风险精神状态评估（CAARMS）是识别符合精神病超高风险（UHR）标准的个体的最广泛使用的工具之一，但CAARMS 的韩语版本（CAARMS-K）的心理测量特性尚未得到研究。因此，我们在韩国人群中测试了 CAARMS-K 的可靠性、有效性和因子结构。
CAARMS-K 被用于 96 名 UHR 个体。评估了 CAARMS-K 的评分者间信度和内部一致性。此外，使用主轴因子分析研究了其因子结构。通过使用 Spearman 相关检验，将提取的 CAARMS-K 因子与阳性和阴性症状量表（PANSS）的五个因子进行比较，来检验同时效度。在 1 年和 2 年时检查向精神病的转化率。
评分者间信度良好（组内相关系数=0.89），内部一致性可接受（克朗巴赫α=0.812）。五因素解决方案表现出最佳的简单结构，占所有项目方差的 43.1%。因子分析中提取的五个因子与 PANSS 的五个因子相似，并与 PANSS 因子显著相关。在 96 名 UHR 个体中，11 名（11.5%）和 17 名（17.7%）在 1 年和 2 年的随访中分别发展为精神病。
CAARMS-K 是评估韩国 UHR 个体的可靠有效的工具。
