Completed

• Conditions: Cross-cultural Adaptation, Evaluation and Validation Study of Wang Qi's Constitution in TCM Questionnaire (For Old Person)

• Registration Number: NCT04491890
• Lead Sponsor: Hong Kong Baptist University

Brief Summary

This is a cross-cultural adaptation, evaluation and validation study of Wang Qi's Constitution in TCM questionnaire (For Old Person) in Hong Kong to investigate the content validity, construct validity and reliability of the CTCMQ-C in Cantonese speaking Hong Kong Chinese elderly population.

Detailed Description

The study includes two steps. Firstly, translation of the questionnaire into Cantonese, followed by cross-cultural adaptation. Ten Chinese Medicine Practitioners (CMPs) and 30 patients will be recruited from the community and the outpatient clinics of Hong Kong Baptist University (HKBU) to evaluate the Constitution in TCM Questionnaire (For Old Person) (Cantonese version) (CTCMQ-C) for content validity by the cognitive debriefing interviews. The content validity indices (CVI) of clarity, relevance and appropriateness of each item of the questionnaire rated by CMPs and patients will be quantified. The interpretations of items and suggestions of rewording by the patients and CMPs will be analyzed qualitatively to identify any item of the questionnaire that is not valid for the Chinese population in Hong Kong. Secondly following the validation study, 264 patients will be recruited. A validated CTCMQ-C will then be generated and will be endorsed by expert panel to use in the subsequent cross-sectional and cohort studies to evaluate the preventive effect with Chinese Medicine approaches. The psychometric properties including construct validity by scaling assumptions, confirmatory factor analysis (CFA) and reliability of the CTMCQ-C will also be tested.
