BACKGROUND
The Sasang constitutional analysis tool (SCAT) is an integrated Sasang constitutional analysis system developed by the Korea Institute of Oriental Medicine. This study aimed to evaluate the reliability of a questionnaire for measuring personality and pathophysiological symptoms that is one of the components of the SCAT.
METHODS
In this study, data were collected from university students in their twenties. Tests were administered twice, with an interval of 4 weeks between tests. Test-retest data from 176 students were collected and used for analysis. Internal consistency reliability was analyzed by using Cronbach's alpha coefficient, and test-retest reliability was analyzed by using Spearman's rank correlation coefficient.
RESULTS
Cronbach's alpha coefficient was 0.788 for personality, 0.511 for eating habits, 0.718 for digestion, 0.667 for heat- or cold-wise penchant, and 0.612 for water ingestion. Spearman's rank correlation coefficients, which were used to assess correlations between test and retest results, ranged from 0.444 to 0.828.
CONCLUSION
The internal consistency and test-retest reliability of the SCAT questionnaire were found to be satisfactory.
背景
四象体质分析工具（SCAT）是韩国韩医学研究院开发的一个综合性四象体质分析系统。本研究旨在评估作为SCAT组成部分之一的用于测量性格和病理生理症状的问卷的可靠性。
方法
在本研究中，收集了20多岁大学生的数据。测试进行了两次，两次测试间隔4周。收集了176名学生的重测数据并用于分析。使用克朗巴哈α系数分析内部一致性信度，使用斯皮尔曼等级相关系数分析重测信度。
结果
性格方面的克朗巴哈α系数为0.788，饮食习惯为0.511，消化功能为0.718，寒热倾向为0.667，饮水量为0.612。用于评估测试结果与重测结果之间相关性的斯皮尔曼等级相关系数在0.444至0.828之间。
结论
发现SCAT问卷的内部一致性和重测信度令人满意。
