摘要

背景：產後睡眠困擾是產後婦女所要面對的重要課題；雖然產後婦女睡眠困擾的相關因素已被探討，但都使用一般性睡眠品質量表，目前缺乏針對產婦睡眠品質特殊性而設計的測量工具。目的：本研究目的是發展一份「產後睡眠品質量表」，並驗證其信度和效度。方法：本研究依據臨床經驗、文獻查證和專家意見編製一份16題「產後睡眠品質量表」，檢定其內部一致性、再測信度、建構效度和收斂效度。樣本來源為南部地區某一醫學中心和一婦產科診所之產後門診，共收集有效樣本202位產後婦女，收案時間為2010年至2011年。結果：「產後睡眠品質量表」經項目分析後，由16題減為14題，其內部一致性為α = .81，5天再測信度為r = .81。進行因素分析萃取出二個因素，分別是「夜晚照顧嬰兒睡眠中斷相關之白天功能障礙」和「身體症狀相關之睡眠無效率」，可解釋44.49%的總變異量，每題因素負荷量介於.43和.76之間。本量表與匹茲堡睡眠品質量表有顯著相關r = .67，顯示其收斂效度。結論：14題「產後睡眠品質量表」經由驗證後，針對測量婦女產後睡眠品質是一份可信、有效與實用的量表，且本量表可作為未來有睡眠困擾的產後婦女介入措施之成效測量工具。

Background: Postpartum sleep disorders are a significant problem for postnatal women. Although factors predisposing postnatal women to sleep disorders have been identified, few sleep quality assessment instruments adequately address these factors. Purpose: This study aimed to develop a Postpartum Sleep Quality Scale (PSQS) and test its psychometric properties. Methods: Sixteen PSQS items were generated from clinical practice, a literature review, and expert recommendations. Two hundred two postpartum women were recruited from a medical center and an obstetric clinic in southern Taiwan in 2010-2011 to assess the internal consistency, test-retest reliability, construct validity, and convergent validity of the developed PSQS. Results: Item analysis removed two of the initial PSQS items. The resultant 14-item PSQS showed good internal consistency (α = .81) and acceptable 5-day test-retest reliability (r = .81). Construct validity was confirmed using exploratory factor analysis, which extracted and defined ”Infant night care-related daytime dysfunction” and ”Physical symptoms related sleep inefficiency” as the two main categories of postpartum sleep quality. These two factors explained 44.49% of total variance, with factor loadings between .43 and .76. Significant correlation (r = .67) with the Pittsburgh Sleep Quality Index showed convergent validity. Conclusion: The 14-item PSQS is a reliable, valid, and useful scale for measuring postpartum sleep quality and examining intervention protocols in Taiwanese postpartum women with sleep disturbance.
