Reliability and Validity Evaluation of the Traditional Chinese Medical Yang-Xu Constitutional Questionnaire on Pregnant Women

摘要


Background: Constitutional changes in pregnant women differ from those in the general adult population. Purpose: The purpose of this study was to establish and test the reliability and validity of the ”Traditional Chinese Medical Yang‐Xu Constitutional Questionnaire (TCMYCQ) ” on pregnant women. Methods: We used a cross‐sectional questionnaire survey and collected data from a convenience sample of 426 pregnant women who received prenatal examinations at obstetrics and gynecology clinics in southern Taiwan. Construct validity was assessed using item analysis and principle component analysis. Results: Results showed a total explained variance of 58.25% and internal consistency reliability (Cronbach's α) of .86 for the TCMYCQ in our sample population. The five factors extracted were ”yang‐qi deficiency in chest”, ”yang‐qi deficiency in head”, ”yang‐qi deficiency in four limbs”, ”yang‐qi deficiency in abdominal cavity”, and ”yang‐qi deficiency on body surface”. The Cronbach's α ranged from .53 − .84 for the five factors; the intraclass correlation coefficient for test‐retest reliability was .90. The correlation coefficients between the 5 factors and the total scale were .77, .82, .73, .69, and .54, respectively, representing significant correlations (p < .0001) that indicate good TCMYCQ convergent validity. Correlation coefficients among the 5 factors ranged from .20 − .53. Because correlation coefficients between the 5 factors and the total scale were all higher than those among the 5 factors, good divergent validity was indicated for this questionnaire. Conclusion: This questionnaire is not only appropriate as an assessment and reference indicator of traditional Chinese medical constitution during pregnancy and reference to help pregnant women adjust their constitution, but also offers evidence‐based data for nurses to provide healthcare guidance.
