Abstract

Objective

The Traumatic Grief Inventory-Self Report Plus (TGI-SR+) measures the most recent prolonged grief disorder (PGD) symptom sets defined in the 11^th edition of the International Statistical of Diseases and Related Health Problems (ICD-11) and the text revision of the fifth edition of the Diagnostical and Statistical Manual of Mental Disorders (DSM-5-TR). However, the TGI-SR+ has not yet been translated and validated in Chinese. This study aims to evaluate the psychometric properties of the Chinese translation of the TGI-SR+.

Methods

We examined the Chinese TGI-SR+'s factor structure, internal consistency, convergent validity, discriminant validity, known-groups validity, and optimal clinical cut-off scores in 443 Chinese bereaved adults.

Results

Confirmatory factor analyses showed that the two-factor models showed the best fit for the Chinese TGI-SR+ items assessing ICD-11 and DSM-5-TR prolonged grief symptoms. Items assessing ICD-11 and DSM-5-TR prolonged grief symptoms demonstrated good internal consistency. Associations of TGI-SR+ scores with symptom levels of prolonged grief (assessed by the International Prolonged Grief Disorder Scale), posttraumatic stress, anxiety, and depression supported convergent and discriminant validity. Associations with background/loss-related variables provided evidence for known-groups validity. Cut-off points for probable ICD-11 PGD (liberal scoring rule), probable ICD-11 PGD (conservative scoring rule), and probable DSM-5-TR PGD were ≥67, ≥75, and ≥68, respectively.

Discussion

The Chinese TGI-SR+ appears to be a reliable and valid measure to assess prolonged grief symptoms per ICD-11 and DSM-5-TR among Chinese bereaved adults.

创伤性悲伤量表--自我报告增强版（TGI-SR+）在中国丧亲人群中的心理测量学评估。

目的：创伤性悲伤量表--自我报告增强版（TGI-SR+创伤性悲伤量表--自我报告增强版（TGI-SR+）测量的是第 11 版《国际疾病和相关健康问题统计》（ICD-11）和第五版《精神疾病诊断和统计手册》（DSM-5-TR）文本修订版中最新定义的长期悲伤障碍（PGD）症状集。然而，TGI-SR+ 尚未翻译成中文并进行验证。本研究旨在评估 TGI-SR+ 中文译本的心理测量学特性：我们以 443 名中国成年丧亲者为研究对象，考察了中文版 TGI-SR+ 的因子结构、内部一致性、收敛效度、区分效度、已知群体效度和最佳临床截断分数：结果：确认性因子分析显示，双因子模型对评估 ICD-11 和 DSM-5-TR 长时间悲伤症状的中文 TGI-SR+ 项目的拟合效果最佳。评估ICD-11和DSM-5-TR长期悲伤症状的项目显示出良好的内部一致性。TGI-SR+ 分数与长时悲伤症状水平（由国际长时悲伤障碍量表评估）、创伤后应激、焦虑和抑郁的相关性支持了收敛性和区分性有效性。与背景/损失相关变量的关联为已知组的有效性提供了证据。可能的ICD-11 PGD（自由评分规则）、可能的ICD-11 PGD（保守评分规则）和可能的DSM-5-TR PGD的临界点分别为≥67、≥75和≥68：讨论：根据ICD-11和DSM-5-TR，中文TGI-SR+似乎是评估中国成年丧亲者长期悲伤症状的可靠而有效的方法。
