Cross-Cultural Adaptation and Psychometric Validation of the Constipation Assessment Scale among Chinese Adult Psychiatric Patients.
Article in International journal of environmental research and public health, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundConstipation 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. PURPOSE: This study aimed to cross-culturally adapt and psychometrically validate the traditional Chinese version of the CAS among adult psychiatric patients in Hong Kong.
methodUsing 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.
resultsThe 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.
conclusionsThe CAS-TC is valid and reliable and can be employed to assess constipation among adult psychiatric patients.
