AB  - AIM: To initially test for the content validity, comprehensibility, test-retest 
      reliability and internal consistency reliability of the Yin-Yang Assessment 
      Questionnaire (YY-AQ). METHODS: The process of initial validity and reliability 
      test covered: (1) content validation from the findings of 18 multiple-case 
      studies, validated Yin- and Yang-deficiency assessment questionnaires, relevant 
      literatures and registered Chinese medicine practitioners; (2) comprehension with 
      the levels of comprehensibility for each item categorized on a 3-point scale (not 
      comprehensible; moderately comprehensible; highly comprehensible). A minimum of 
      three respondents selecting for each item of moderately or highly comprehensible 
      were regarded as comprehensive; (3) test-retest reliability conducted with a 2-wk 
      interval. The intraclass correlation coefficients (ICCs) and their 95%CIs were 
      calculated using a two-way random effects model. Wilcoxon Signed Rank test for 
      related samples was adopted to compare the medians of test-retest scores. An ICC 
      value of 0.85 or higher together with P > 0.05, was considered acceptable; and 
      (4) internal consistency of the total items was measured and evaluated by 
      Cronbach's coefficient alpha (alpha). A Cronbach's alpha of 0.7 or higher was considered 
      to represent good internal consistency. RESULTS: Eighteen Yin-deficiency and 14 
      Yang-deficiency presentation items were finalized from content validation. Five 
      participants with type 2 diabetes mellitus (T2DM) performed the comprehensibility 
      and test-retest reliability tests. Comprehensibility score level of each 
      presentation item was found to be moderate or high in three out of the five 
      participants. Test-retest reliability showed that the single measure ICC of the 
      total Yin-deficiency presentation items was 0.99 (95%CI: 0.89-0.99) and the 
      median scores on the first and 14(th) days were 17 (IQR 6.5-27) and 21 (IQR 6-29) 
      (P = 0.144) respectively. The single measure ICC of the total Yang-deficiency 
      presentation items was 0.88 (95%CI: 0.79-0.99) and the median scores on the first 
      and 14(th) days were 10 (IQR 6-18) and 14 (IQR 7-23) (P = 0.144) respectively. 
      The results of a descriptive correlation study on 140 survey participants with 
      T2DM using the YY-AQ showed that internal consistency of the total Yin-deficiency 
      and Yang-deficiency presentation items was satisfactory, with Cronbach's alpha of 
      0.79 and 0.78 respectively. CONCLUSION: The YY-AQ will be tested further for 
      comprehensibility, test-retest and internal consistency reliabilities, scoring 
      system validity, construct validity, convergent and discriminant validities, 
      responsiveness and predictive validity.
