Abstract

Background: During the gradual decline of physical and social functioning associated with end-stage renal disease, patients might experience a premonition of impending death, resulting in a series of pre-mourning grief responses called preparatory grief. The preparatory grief in advanced cancer patients (PGAC) scale is the most widely used preparatory grief scale for patients on hemodialysis in China.

Aim: To verify the reliability and validity of the PGAC scale in patients on hemodialysis.

Methods: In total, 327 patients undergoing regular hemodialysis in the blood purification center of three grade-A tertiary hospitals in Guangdong and Guizhou provinces were selected by convenience sampling. The assessment was administered using the general information questionnaire and the Chinese version of PGAC. SPSS 25.0 and Amos 24.0 were used for item analysis, confirmatory factor analysis (CFA), convergent validity, and internal consistency reliability estimation.

Results: In the modified Chinese version of PGAC, 7 dimensions covering 27 total items were retained. CFA revealed a good fit of the factor model (chi-square degree of freedom = 2.056, standardized root mean square residual = 0.0479, root mean square error of approximation = 0.0570, GFI = 0.872, AGFI = 0.841, IFI = 0.931, CFI = 0.930, TLI = 0.919). The factor loadings of the items ranged 0.503-0.884. The composite reliability ranged 0.664-0.914, and the average variance extracted ranged 0.366-0.747. Cronbach's α of the scale was 0.945, and Cronbach's α for various dimensions ranged 0.662-0.914.

Conclusion: The modified PGAC has good reliability and validity, and it can effectively measure preparatory grief in patients on hemodialysis.

预备悲伤量表用于血液透析患者的信度和效度。

背景：在与终末期肾病相关的身体和社会功能逐渐下降的过程中，患者可能会体验到即将到来的死亡预感，导致一系列的哀悼前悲伤反应，称为预备悲伤。晚期癌症患者预备悲伤量表（PGAC）是国内使用最广泛的血液透析患者预备悲伤量表。目的：验证血液透析患者PGAC量表的信度和效度。方法：采用方便抽样法抽取广东、贵州三家三级甲等医院血液净化中心定期接受血液透析的患者327例。采用一般信息问卷和中文版PGAC进行评估。采用SPSS 25.0和Amos 24.0进行项目分析、验证性因子分析（CFA）、收敛效度和内部一致性信度估计。结果：修改后的中文版PGAC保留了7个维度共27个项目。结果表明，因子模型拟合良好（卡方自由度= 2.056，标准化均方根残差= 0.0479，近似均方根误差= 0.0570,GFI = 0.872, AGFI = 0.841, IFI = 0.931, CFI = 0.930, TLI = 0.919）。各项目的因子负荷范围为0.503 ~ 0.884。复合信度范围为0.664 ~ 0.914，提取的平均方差范围为0.366 ~ 0.747。量表的Cronbach’s α为0.945，各维度的Cronbach’s α为0.662 ~ 0.914。结论：改进的PGAC量表具有良好的信效度，能有效地测量血液透析患者的预备悲伤。

期刊介绍： The World Journal of Psychiatry (WJP) is a high-quality, peer reviewed, open-access journal. The primary task of WJP is to rapidly publish high-quality original articles, reviews, editorials, and case reports in the field of psychiatry. In order to promote productive academic communication, the peer review process for the WJP is transparent; to this end, all published manuscripts are accompanied by the anonymized reviewers’ comments as well as the authors’ responses. The primary aims of the WJP are to improve diagnostic, therapeutic and preventive modalities and the skills of clinicians and to guide clinical practice in psychiatry.
