Psychometric evaluation of the Chinese version of the Elderly- Constipation Impact Scale: A translation and validation study

Abstract Objective The objective of this study was to translate the Elderly-Constipation Impact Scale into Chinese and to examine its reliability and validity in a population of older people suffering from chronic constipation. Methods A total of 564 elderly chronically constipated patients were recruited for this study. The general information questionnaire and the Chinese version of the Elderly-Constipation Impact Scale (E-CIS) were used to survey them. The reliability of the Chinese questionnaire is assessed by internal consistency, split-half reliability, and retest reliability. Content validity indicators and structural validity indicators were used to assess the validity of the scale. Results The Chinese version of the Constipation Impact Scale for the Elderly has an appropriate level of reliability. The split-half reliability is 0.736 and the stability is 0. 763. The content validity and structural validity indicators are within reasonable limits. Conclusion The Chinese version of the E-CIS has good reliability and validity in the chronic constipation population of the elderly. The results of the questionnaire can effectively and comprehensively reflect the impact of chronic constipation on the quality of life of the elderly. It provides a meaningful reference for identifying targets for intervention.
