背 景：懷孕的體質變化與一般成人是有所差異的。目 的：本研究目的在建構與測試「中醫陽氣虛體質量表」之孕期信、效度。方 法：採橫斷性問卷調查法，方便取樣426位南部醫院婦產科門診之孕婦的相關資料，並以項目分析及主成分分析法測試量表之建構效度。結 果：「中醫陽氣虛體質量表」的總解釋變異量為58.25%，內在一致性信度Cronbach’s α值為 .86，所萃取的五個因素為「胸腔陽氣不足」、「頭部陽氣不足」、「肢體陽氣不足」、「腹腔陽氣不足」以及「體表陽氣不足」，其Cronbach’s α值介於 .53 − .84；再測信度組內相關係數為 .90；五個因素與總量表之相關係數分別為 .77、.82、.73、.69、.54，且均達顯著性相關(p < .0001)，表示量表的收斂效度良好；各因素間的相關係數介於 .20 − .53，且五個因素與總量表的相關係數均高於各因素間的相關係數，表示量表的分殊效度不錯。結 論：本量表可作為孕期中醫體質的評估及具體參考指標，提供孕期調整體質的重要依據，並可作為健康照護人員提供護理指導的實證方向。

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 factor ; 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.
