Learning Objective 1: The learner will be able to known a new tool to evaluate Ying-Xu body constitution in Traditional Chinese Medicine.
Learning Objective 2: The learner will be able to understand the measurement items in Ying-Xu body constitution in Traditional Chinese Medicine.
Methods: The questionnaire of BCQ- was developed using a step-by-step approach: 1) to form the research team and select a panel of 38 experts who had both MM and TCM educational background and professional training for Delphi method; to generate questionnaire items from literature review and Delphi process, refine these items to be colloquially acceptable, and evaluate their face and content validity by Delphi process again; 2) to evaluate the difficulty of answering these questions by pilot study with 81 subjects whose age were between 20-60; 3)eight hundred and twenty one eligible participants, aged between 20-60, no disease onset in the past month, and receiving health examination in teaching hospitals were recruited to test the reliability and validity; 4) criterion- related validity was approval by 150 subjects
Results: Nineteen out of the 22 items from BCQ- were developed. Exploratory factor analysis identified 5 domains that represent and correspond to the manifestations of the diminishing material level in 5 different body areas: Yin-blood-Xu in the head, four limbs, gastrointestinal tract, body surface, and abdominal cavity. The Cronbach’s coefficient alpha (α) ranged from 0.57-0.77 and the intraclass correlation coefficients were greater than 0.7 for most of the 19 questions. The concurrent validity for BCQ- in TCM physision and Hemoglobin showed consistent agreements.
Conclusion: Five domains with 19 items in BCQ- were developed. BCQ- is a valid and potentially useful tool for evaluating the Yin-blood-Xu constitution in clinical practices and researches.
