Abstract

Background: Prolonged grief disorder (PGD) has been added to the ICD-11 and DSM-5-TR. The Traumatic Grief Inventory-Self Report Plus (TGI-SR+) assesses self-rated PGD intensity as defined in ICD-11 and DSM-5-TR. The TGI-SR + is available in multiple languages, but has not been validated yet in Norwegian.Objective: The aim of this study was to evaluate the psychometric properties of the Norwegian TGI-SR + .Method: Bereaved adults (N = 307) whose child or sibling died ≥6 months ago due to a sudden or violent loss completed the TGI-SR + and measures for posttraumatic stress, depression, and precursor PGD symptoms. We examined the factor structure and internal consistency of the ICD-11 and DSM-5-TR PGD items. Convergent validity and known-groups validity was evaluated. Probable PGD cases, pair-wise agreement between diagnostic scoring rules for both PGD criteria-sets, and cut-off scores were calculated.Results: The 1-factor model for ICD-11 and DSM-5-TR PGD showed the best fit and demonstrated good internal consistency. Convergent validity was supported by strong associations between summed ICD-11 and DSM-5-TR PGD scores and summed posttraumatic stress, depression, and precursor prolonged grief scores. Known-groups validity was supported by PGD intensity being related to educational level and time since loss. The perfect pair-wise agreement was reached using the ICD-11 and DSM-5-TR PGD diagnostic scoring rules. The optimal cut-off score for detecting probable PGD cases, when summing all TGI-SR + items, was ≥73.Conclusions: The Norwegian TGI-SR + seems a valid and reliable instrument to assess ICD-11 and DSM-5-TR PGD intensity after losing a child or sibling under traumatic circumstances.

挪威创伤性悲伤清单--自我报告强化版(TGI-SR+):对创伤性丧亲人群的心理测量评估。
背景:长期悲伤障碍(PGD)已被列入 ICD-11 和 DSM-5-TR。创伤性悲伤量表--自我报告增强版(TGI-SR+)可评估ICD-11和DSM-5-TR中定义的自我评定的PGD强度。TGI-SR+ 有多种语言版本,但尚未在挪威语中得到验证:本研究旨在评估挪威语 TGI-SR + 的心理测量特性:其子女或兄弟姐妹在≥6个月前因突然或暴力丧生的失去亲人的成年人(N = 307)填写了TGI-SR +和创伤后应激反应、抑郁和PGD前兆症状测量表。我们研究了 ICD-11 和 DSM-5-TR PGD 项目的因子结构和内部一致性。我们还评估了收敛有效性和已知群体有效性。计算了可能的 PGD 病例、两套 PGD 标准的诊断评分规则之间的配对一致性以及临界分数:结果:ICD-11 和 DSM-5-TR PGD 的单因素模型显示出最佳拟合度和良好的内部一致性。ICD-11 和 DSM-5-TR PGD 的总分与创伤后应激反应、抑郁和前兆性长期悲伤的总分之间存在很强的关联,这支持了聚合效度。PGD强度与教育水平和丧亲时间相关,这也支持了已知群体有效性。通过使用 ICD-11 和 DSM-5-TR PGD 诊断评分规则,达到了完美的双向一致性。将所有TGI-SR +项目相加,检测可能的PGD病例的最佳临界分数为≥73.结论:挪威TGI-SR +似乎是评估在创伤情况下失去子女或兄弟姐妹后ICD-11和DSM-5-TR PGD强度的有效而可靠的工具。

期刊介绍: The European Journal of Psychotraumatology (EJPT) is a peer-reviewed open access interdisciplinary journal owned by the European Society of Traumatic Stress Studies (ESTSS). The European Journal of Psychotraumatology (EJPT) aims to engage scholars, clinicians and researchers in the vital issues of how to understand, prevent and treat the consequences of stress and trauma, including but not limited to, posttraumatic stress disorder (PTSD), depressive disorders, substance abuse, burnout, and neurobiological or physical consequences, using the latest research or clinical experience in these areas. The journal shares ESTSS’ mission to advance and disseminate scientific knowledge about traumatic stress. Papers may address individual events, repeated or chronic (complex) trauma, large scale disasters, or violence. Being open access, the European Journal of Psychotraumatology is also evidence of ESTSS’ stand on free accessibility of research publications to a wider community via the web. The European Journal of Psychotraumatology seeks to attract contributions from academics and practitioners from diverse professional backgrounds, including, but not restricted to, those in mental health, social sciences, and health and welfare services. Contributions from outside Europe are welcome. The journal welcomes original basic and clinical research articles that consolidate and expand the theoretical and professional basis of the field of traumatic stress; Review articles including meta-analyses; short communications presenting new ideas or early-stage promising research; study protocols that describe proposed or ongoing research; case reports examining a single individual or event in a real‑life context; clinical practice papers sharing experience from the clinic; letters to the Editor debating articles already published in the Journal; inaugural Lectures; conference abstracts and book reviews. Both quantitative and qualitative research is welcome.
