The loss of a significant person can lead to a broad spectrum of responses. While most individuals gradually recover within a year, a minority develop Prolonged Grief Disorder (PGD). The Traumatic Grief Inventory Self-Report Plus (TGI-SR+) was recently developed to ensure that the original scale (TGI-SR) still accurately assesses PGD in line with the latest diagnostic standards of the DSM-5-TR and ICD-11. This study aimed to validate the TGI-SR+ within two French-speaking cohorts: 276 French-Canadian and 469 Belgian participants. Data were collected through an online survey in 2022. Confirmatory factor analysis resulted in a 4-factor model for the TGI-SR+ total scale, but high inter-item correlations favored a 1-factor solution. A 1-factor model was found for the DSM-5-TR and ICD-11 PGD scores. Convergent validity with mental health disorder, depression, and post-traumatic growth, and known-group validity were confirmed. The findings endorse the TGI-SR+ as a valid tool for detecting potential PGD.
重要人物的离世可能会引发一系列广泛的反应。虽然大多数人在一年内会逐渐恢复，但少数人会患上持续性悲伤障碍（PGD）。创伤性悲伤量表自我报告升级版（TGI-SR+）最近被开发出来，以确保原始量表（TGI-SR）仍能根据《精神疾病诊断与统计手册》第5版修订版（DSM-5-TR）和《国际疾病分类》第11版（ICD-11）的最新诊断标准准确评估PGD。本研究旨在验证TGI-SR+在两个说法语的队列中的有效性：276名法裔加拿大参与者和469名比利时参与者。数据于2022年通过在线调查收集。验证性因素分析得出TGI-SR+总量表的四因素模型，但项目间的高相关性支持单因素解决方案。在DSM-5-TR和ICD-11的PGD评分中发现了单因素模型。与心理健康障碍、抑郁症和创伤后成长的收敛效度以及已知群体效度得到了证实。研究结果认可TGI-SR+作为检测潜在PGD的有效工具。
