背景资料：本研究调查了长时间悲伤障碍（PGD）、抑郁症和创伤后应激障碍（PTSD）的症状特征。我们比较了一个单因素模型的拟合与四个层次模型的拟合，其中症状形成三个不同的相关高阶维度，PTSD项目以不同的方式建模。方法：自我报告的数据来自两个样本; 572哀悼者通过互联网和408哀悼者通过医疗工作者招募。四个层次模型都拟合得更好。其中PTSD项目构成四个低阶因素的再体验，回避，烦躁不安，和过度觉醒的模型拟合数据最好。当删除一个弱PGD项目和一个弱PTSD项目时，拟合进一步改善，并且允许相似项目的错误项相关。样本1的结果在样本2中重复。局限性：本研究依赖于自我报告的数据。并非所有PGD标准和抑郁标准都得到了评估。结论：这是第一个验证性因素分析研究，表明PGD、抑郁和PTSD的症状代表了可区分的综合征。在评估和治疗寻求治疗的丧失亲人的人时，应解决PGD症状。(C)2010爱思唯尔有限公司版权所有。
Background: This study examined the distinctiveness of symptoms of Prolonged Grief Disorder (PGD), depression, and posttraumatic stress disorder (PTSD). We compared the fit of a one-factor model with the fit of four hierarchical models in which symptoms formed three distinct correlated higher-order dimensions, and PTSD-items were modeled in different ways.Methods: Self-reported data were available from two samples; 572 mourners recruited via the internet and 408 mourners recruited via healthcare workers.Results: In Sample 1, the unitary model did not fit the data. The four hierarchical models all fit better. The model in which PTSD-items constituted four lower-order factors of reexperiencing, avoidance, dysphoria, and hyperarousal fit the data best. The fit was further improved, when one weak PGD-item and one weak PTSD-item were removed, and error-terms of similar items were allowed to correlate. Findings from Sample 1 were replicated in Sample 2.Limitations: This study relied on self-reported data. Not all PGD-criteria and depression-criteria were assessed.Conclusions: This is the first confirmatory factor analysis study showing that symptoms of PGD, depression, and PTSD represent distinguishable syndromes. PGD-symptoms should be addressed in the assessment and treatment of bereaved people seeking treatment. (C) 2010 Elsevier B.V. All rights reserved.
