The International Classification of Diseases Eleventh Edition (ICD-11), and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR), now include prolonged grief disorder (PGD). Since criteria for PGD in both classification systems differ from prior proposed grief disorders and each other, the validation of a single instrument to screen for prolonged grief (PG) symptoms of both new diagnoses is critical for bereavement research and care. Therefore, we evaluated the psychometric properties of the Swedish version of the Traumatic Grief Inventory Self-Report Plus (TGI-SR+). Two-hundred and forty-eight bereaved parents completed questions about sociodemographic and loss-related variables, the TGI-SR+, and symptom measures of post-traumatic stress (PTS), depression and an older measure of PG symptoms, the Prolonged Grief Disorder-13 (PG-13). Confirmatory factor analyses showed that a one-factor model best fit DSM-5-TR and ICD-11 PG symptoms and the analyses of the internal consistency and inter-item correlations showed that these symptoms could be reliably assessed. In support of convergent validity, DSM-5-TR and ICD-11 PG symptoms correlated with symptoms of PTS, depression and PG assessed with the PG-13. In support of known-groups validity, DSM-5-TR and ICD-11 PG symptoms were higher among lower educated (vs. higher educated) participants and related negatively to time since loss. ROC analyses showed optimal cut-off score of ≥71 and ≥72 to determine probable caseness for DSM-5-TR and ICD-11 PGD, respectively. Results support the reliability and validity of the Swedish TGI-SR+ as a screening instrument for PG in research and bereavement care.
《国际疾病分类第十一次修订本》（ICD - 11）以及《精神疾病诊断与统计手册》第五版修订本（DSM - 5 - TR）现已纳入持续性悲伤障碍（PGD）。由于这两个分类系统中PGD的标准与先前提出的悲伤障碍不同，且彼此之间也存在差异，因此，验证一种单一工具来筛查这两种新诊断的持续性悲伤（PG）症状，对于丧亲研究和护理至关重要。因此，我们评估了瑞典版创伤性悲伤量表自我报告升级版（TGI - SR +）的心理测量特性。248名丧亲父母完成了关于社会人口统计学和与丧失相关变量的问题、TGI - SR +，以及创伤后应激（PTS）、抑郁症状测量，还有一个较旧的PG症状测量工具——持续性悲伤障碍 - 13（PG - 13）。验证性因素分析表明，单因素模型最能拟合DSM - 5 - TR和ICD - 11的PG症状，内部一致性和项目间相关性分析表明这些症状能够得到可靠评估。为支持聚合效度，DSM - 5 - TR和ICD - 11的PG症状与PTS、抑郁症状以及用PG - 13评估的PG症状相关。为支持已知群体效度，在受教育程度较低（与受教育程度较高相比）的参与者中，DSM - 5 - TR和ICD - 11的PG症状得分更高，且与丧失后的时间呈负相关。ROC分析表明，分别确定DSM - 5 - TR和ICD - 11 PGD可能病例的最佳截断分数为≥71和≥72。结果支持瑞典版TGI - SR +作为研究和丧亲护理中PG筛查工具的可靠性和有效性。
