    摘要: 背景:
    咽喉逆流指胃中的內容物逆流而產生慢性咽喉的症狀或徵兆,此病徵不僅會造成咽喉逆流患者的慢性困擾,且須接受長期治療及定期回診。因為咽喉逆流的症狀大都出現在咽喉部位,因此這類患者經常會先前往耳鼻喉科就診,當耳鼻喉科醫師懷疑此患者症狀可能係逆流所引起的,有時會將其轉診至腸胃科再進行診斷與治療。此類患者在尚未確定診斷前,將其稱為疑似咽喉逆流患者。儘管適用此逆流患者族群的各類型的問卷漸被發展或驗證,但針對疑似咽喉逆流患者族群的健康相關生活品質的問卷則不多,中文版本更是缺乏,亟需發展。
    目的:
    本研究之目的則係針對GERDyzer中文版問卷用於疑似咽喉逆流患者之信效度驗證,並了解此問卷的適用性。
    方法:
    研究對象為台中榮民總醫院耳鼻喉科門診中,因有慢性咽喉逆流相關症狀轉診至腸胃科的患者,共103位。除臨床醫師評估外並針對疑似咽喉逆流患者治療前施測逆流相關症狀、生活品質與焦慮及憂鬱之問卷量表,針對以氫離子幫浦阻斷劑(PPI)治療之患者,在第4週、8週及12週追蹤其經藥物治療後之生理與生活品質變化情形。並進一步探討GERDyzer中文版問卷信效度,包含有內部一致性、再測信度、建構效度、區辨效度及反應性分析等。
    結果:
    GERDyzer中文版問卷用於疑似咽喉逆流患者之內部一致性指標Cronbach's α值為0.94;再測信度使用ICC值檢定,問卷總分ICC值為0.774 ,各題目之ICC值範圍介於0.865-0.971。區辨效度分析結果發現,在RSI以14分為切點及HADs問卷焦慮範疇以8分或11分為切點三個組別呈現統計上顯著差異;在建構效度部分分析結果得GERDyzer總分與RSI及HADs中焦慮範疇分數有中等程度相關,並且治療4、8、12週後之變化也有顯著相關。再反應性部分,分析結果以GERDyzer總分來看,隨著治療之時間之增加,患者的生活品質有逐漸變好的趨勢,若細分成有無典型GERD症狀,亦可得到相類似的結果;以Effect size比較患者治療滿12週與治療前比較,無論總分或各題分數皆有良好之反應性。
    結論:
    本研究結果顯示GERDyzer中文版問卷使用於疑似咽喉逆流患者有良好的信效度,且因此份問卷簡短,短時間可填答完成,使用上之可行性很高。並可適用於食道內、食道外、或疑似咽喉逆流患者,使其適用面更廣。
    Background:

    Laryngopharyngeal reflux (LPR) is the result of retrograde flow of gastric contents to the laryngopharynx, which causes chronic or intermittent laryngopharyngeal symptoms. Currently there are few Chinese version quality of life questionnaires for suspected LPR patients.

    Aim:

    To establish the reliability, validity, and responsiveness of a disease-specific assessment tool, the GERDyzer (Chinese version), which assesses patient-reported outcomes (PRO) with regard to health-related quality of life (HRQoL) of suspected LPR patients.

    Methods:

    This study was conducted as a single-center multidisciplinary open label, therapeutic trial involving the Voice & Laryngeal Pathology Laboratory and Gastrointestinal Physiology & Motility Laboratory in Taichung Veterans General Hospital, Taiwan. Subjects completed three questionnaires: GERDyzer, RSI and HADs. The outcome assessment was performed at baseline (visit 1), week 4 (visit 2), week 8 (visit 3), and week 12 (visit 4) during the PPI treatment period.

    Results:

    Validation of GERDyzer indicated high internal consistency (Cronbach’s a = 0.94) and test–retest reliability (intraclass correlation coefficient =0.774). Responsiveness of the total score expressed by nonparametric effect size was 1.14. The correlations showed strong relationships of GERDyzer total scores with RSI score and anxiety score.

    Conclusion:

    In this study, the GERDyzer (Chinese version) questionnaire displayed good reliability, validity, and responsiveness, so it may provide physicians and patients with a better understanding of the HRQoL burden of suspected LPR and the impact of therapy. The study’s findings demonstrated that the Chinese version of the GERDyzer questionnaire was useful for suspected LPR patients and may be of value in clinical practice.
