All participants were asked to complete a basic information questionnaire before CHM treatment and an assessment of their TCM constitution. The CCMQ consisted of 60 items (clinical observations, indicators of constitutions, Table 2) categorized into 9 subscales, each measuring one of the 9 different body constitutions, namely, Yang-deficient (7 items), Yin-deficient (8 items), Qi-deficient (8 items), Phlegm-dampness (8 items), Damp-heat (6 items), Stagnant Blood (7 items), Inherited Special (7 items), Stagnant Qi (7 items), and Balanced (8 items). The items were on a 5-point Likert scale, with high scores indicating a higher likelihood of having the given constitution. Usually, a threshold of 30 or higher points on a subscale was used to classify a person as having that body constitution.
