The Constipation Severity Instrument (CSI) is a well-validated measure for assessing constipation severity. At present, no translated traditional Chinese version of the scale is available. We aimed to develop a traditional Chinese version of the CSI and to validate the translated version.
The CSI questionnaire was translated into traditional Chinese language, followed by linguistic validation. It was tested on 45 constipated patients and 55 controls from colorectal outpatient clinics and volunteers. A retest was performed in a subgroup of 39 patients 2 weeks later. Convergent validation was assessed using the Cleveland constipation scoring system (CSS) and quality of life was assessed with the 12-item short-form health survey (SF-12). The reliability and validity were assessed using Cronbach's α coefficient, intraclass correlation coefficient (ICC), and the Spearman correlation test.
Cronbach's α coefficient for the CSI total score and its three subscale scores were all above 0.93. Test-retest reliability was good for the CSI total score (ICC = 0.865) and its three subscale scores (ICC = 0.709-0.882). The constipated participants could be effectively differentiated from the controls based on the CSI total score and its three subscales. The convergent validation was good between the CSI and CSS (Spearman's ρ = 0.711, p < 0.001). The CSI score correlated negatively with the physical composite score and mental composite score of the SF-12 quality of life scale, indicating poorer quality of life in constipated patients.
We demonstrated the reliability and validity of the traditional Chinese version of the CSI, which could be a standardized tool for future studies on constipation.
便秘严重度指数（CSI）是一种评估便秘严重程度的经过充分验证的测量工具。目前，该量表尚无翻译的繁体中文版。我们旨在开发 CSI 的繁体中文版并对其进行验证。
将 CSI 问卷翻译成繁体中文，然后进行语言验证。在结直肠门诊和志愿者中，对 45 名便秘患者和 55 名对照者进行了测试。在 2 周后对 39 名患者的亚组进行了重测。使用克利夫兰便秘评分系统（CSS）评估了聚合验证，使用 12 项简短健康调查（SF-12）评估了生活质量。使用 Cronbach's α 系数、组内相关系数（ICC）和 Spearman 相关检验评估了可靠性和有效性。
CSI 总分及其三个分量表的 Cronbach's α 系数均大于 0.93。CSI 总分和三个分量表的重测信度良好（ICC = 0.865 和 0.709-0.882）。根据 CSI 总分及其三个分量表，可有效区分便秘患者和对照组。CSI 与 CSS 之间的聚合验证良好（Spearman's ρ = 0.711，p < 0.001）。CSI 评分与 SF-12 生活质量量表的身体成分评分和心理成分评分呈负相关，表明便秘患者的生活质量较差。
我们证明了 CSI 繁体中文版的可靠性和有效性，它可以成为未来便秘研究的标准化工具。
