中文版反芻型反應量表在台灣憂鬱症病人之信效度驗證

Validation of the Ruminative Response Scale-Chinese Version (RRS-C) for Persons with Depression in Taiwan

目的：本研究主要在驗證中文版反芻型反應量表應用於台灣臨床憂鬱症患者之信度與效 度，並特別著重在因素結構分析及辨別憂鬱反芻傾向顯著與否之臨界值分數探究。方法： 本研究共招募143 位來自精神科門診或日間病房且被診斷罹患憂鬱相關疾病的受試者，並利 用自填量表來收集個案資料，包括中文版反芻型反應量表 (Ruminative Response Scale-Chinese version, RRS-C)、貝克憂鬱量表二版中文版 (Beck Depression Inventory-II, BDI)、活動參與及 限制問卷 (Activity Participation and Restriction Questionnaire, APRQ) 等，再透過探索性因素分 析及接收者操作特徵曲線進行資料分析。結果：本研究發現中文版反芻型反應量表包含「內 省」、「孤立」和「自我專注」等三因素；簡短中文版反芻型反應量表包含「鬱悶沈思」及 「仔細考慮」等二因素。前揭各因素之內部一致性介於可接受到良好等級。結論：中文版反 芻型反應量表在台灣臨床憂鬱症患者之施測上具有可被接受的信效度，同時可辨別出高度憂 鬱反芻傾向且日常活動參與狀況受到影響的個案，故具有應用於臨床實務之潛力及價值。

Objectives: In this study, we intended to validate the Ruminative Response Scale-Chinese version (RRS-C), a measure of rumination that has been translated and used to evaluate the intensity of ruminative responses in clinically depressed patients in Taiwan, as well as to examine the factor structure of the RRS-C and determined cut-off scores for identifying patients with prominent rumination tendencies. Methods: We recruited study participants from day care centers or clinics of several hospitals in Taiwan. Study instruments included the RRS-C, Beck Depression Inventory-II, as well as Activity Participation and Restriction Questionnaire. Results: Totally 143 participants were enrolled in this study. Three factors, “symptom-based rumination,” “isolation/introspection,” and “analyzing to understand,” were labeled for the RRS-C, and two factors, “brooding,” and “refl ection,” for the brief RRS-C. Values of Cronbach’s alpha for the factors were ranged from acceptable to excellent. Conclusion: The RRS-C has acceptable validity and reliability to be applied on depressed Taiwanese patients for screening and diagnosis. This scale has also been demonstrated the potential and value to detect depressed patients with high rumination tendency and those who suffer from not well engaging daily activities in Taiwan.
