简版优逝问卷的汉化及其在癌症患者丧亲家属中的信度、效度检验 [中文引用][英文引用]

目的  汉化并检验简版优逝问卷（good death inventory- short form，GDI-SF）在癌症患者丧亲家属群体中的信度、效度。方法  通过翻译、整合、回译、专家委员会审核及预调查形成中文版 GDI-SF。采用便利抽样法对 699 名癌症患者丧亲家属进行调查，检验中文版 GDI-SF 的信度、效度。结果  305 名癌症患者丧亲家属完成研究。中文版 GDI-SF 的条目水平内容效度指数、量表水平的平均内容效度均为 1.00。探索性因子分析共提取 5 个公因子，包括专业医疗照护（6 个条目）、告别准备（4 个条目）、尊严与人生价值（4 个条目）、自然死亡与精神支持（2 个条目）、身心舒适（2 个条目），累计方差解释率为 52.176%。中文版 GDI-SF 的总体 Cronbach α 系数为 0.779，折半信度为 0.731。中文版 GDI-SF 的每个条目得分与其所属维度得分的Pearson 相关系数范围为 0.591~0.769（P<0.01）。结论  中文版 GDI-SF 具有较好的信度和效度，可从丧亲家属视角快速、有效地评估癌症患者的优逝水平。

Objective To translate the good death inventory-short form（GDI-SF）into Chinese and test its reliability and validity among bereaved family members of cancer patients. Methods A Chinese version of GDI-SF was created through translation, reconciliation, back translation, expert panel review and pilot testing. Then the inventory was administered to 699 bereaved family members of cancer patients recruited by convenience sampling. Reliability and validity were assessed. Results Toally 305 family members finished the study. The item-level content validity index（I-CVI）and average content validity index（S-CVI/Ave）were both 1.00. Exploratory factor analysis yielded 5 common factors：professional medical care（6 items）, preparation for farewell（4 items）, dignity and life value（4 items）, natural death and moral support（2 items）, and physical and mental comfort（2 items）. These factors explained 52.176% of total variance. Overall Cronbach α coefficient of the Chinese version GDI-S was 0.779, and split-half reliability was 0.731. The Pearson correlation coefficient range between the score of each item of the Chinese version of GDI-SF and the score of its corresponding dimension was 0.591 to 0.769（P<0.01）. Conclusion The Chinese version GDI-SF exhibits acceptable reliability and validity assessment of the quality of good dying in cancer patients from the perspective of bereaved family members.
