Constipation is a functional gastrointestinal disorder that presents with signs and symptoms, which are typically assessed subjectively. Various measurement scales, such as the Constipation Assessment Scale (CAS), are commonly used to evaluate constipation among the general population. However, the instruments should be culturally and contextually relevant in adult psychiatric patients to generate valid and reliable evidence.
This study aimed to cross-culturally adapt and psychometrically validate the traditional Chinese version of the CAS among adult psychiatric patients in Hong Kong.
Using the Brislin protocol and Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) guidelines, the CAS was translated into traditional Chinese and tested for internal consistency, test-retest reliability, content validity, and construct validity among psychiatric patients in Hong Kong.
The CAS was successfully translated into CAS-TC. The CAS-TC version demonstrated good content validity (scale level CVI = 97%), internal consistency (Cronbach's alpha = 0.79), and test-retest reliability (ICC = 0.722 [95% CI, 0.587-0.812]). The CAS-TC showed a two-factor loading for the construct validity, which explained 54% of the total variance.
The CAS-TC is valid and reliable and can be employed to assess constipation among adult psychiatric patients.
便秘是一种功能性胃肠疾病，表现为症状和体征，这些症状和体征通常是主观评估的。各种测量量表，如便秘评估量表（CAS），常用于评估普通人群中的便秘。然而，在成年精神科患者中，这些工具应该具有文化和背景相关性，才能产生有效和可靠的证据。
本研究旨在对香港成年精神科患者的 CAS 进行跨文化适应性和心理测量学验证。
使用 Brislin 协议和共识基础的健康测量仪器选择标准（COSMIN）指南，将 CAS 翻译成中文，并对香港精神科患者进行内部一致性、重测信度、内容效度和结构效度测试。
CAS 成功地被翻译成了 CAS-TC。CAS-TC 版本具有良好的内容效度（量表水平 CVI = 97%）、内部一致性（Cronbach's alpha = 0.79）和重测信度（ICC = 0.722 [95% CI，0.587-0.812]）。CAS-TC 的结构效度表现出双因素负荷，解释了总方差的 54%。
CAS-TC 是有效和可靠的，可以用于评估成年精神科患者的便秘。
