Abstract

The Inventory of Complicated Grief (ICG) is the most widely used instrument to assess the severity of prolonged grief reactions after the loss of a loved one. The purpose of the present study was to investigate the psychometric properties of the Norwegian ICG by examining its reliability, factor structure, and relationships with the anxiety and depression subscales of the Brief Symptom Inventory, the Integration of Stressful Life Events Scale – Short Form, and the Work and Social Adjustment Scale. The results showed that the Norwegian ICG has high reliability ( ωt = .95). Exploratory factor analysis yielded three factors (disbelief/bitterness, detachment, yearning/hallucinations) that align with factors found in previous investigations. With regard to external validity, moderate to high correlations with symptoms of anxiety and depression, difficulties with integration of the loss, and functional impairment were found. The results support the use of the ICG in bereaved populations in Norway.»/>

挪威一般丧亲样本复杂悲伤量表(ICG)的信度、因素结构和效度

复杂悲伤清单（ICG）是评估失去亲人后长期悲伤反应严重程度的最广泛使用的工具。本研究的目的是通过检查挪威ICG的可靠性、因素结构以及与简短症状量表、压力生活事件综合量表-简表和工作与社会适应量表的焦虑和抑郁分量表的关系，来调查其心理测量特性。结果表明，挪威ICG具有较高的可靠性（ωt=.95）。探索性因素分析得出了三个因素（怀疑/痛苦、超然、渴望/幻觉），与先前调查中发现的因素一致。在外部有效性方面，发现与焦虑和抑郁症状、整合损失困难和功能损害之间存在中度至高度相关性。研究结果支持在挪威丧亲者中使用ICG。»/>
