本研究的目的是评估复杂性悲伤（CG）的因子结构，并通过评估两个结构相结合的模型，探讨CG和创伤后应激障碍（PTSD）之间的关系。该问卷由老年人完成，已婚受访者至少有一个显着的，人际关系的损失（145名男性和147名女性，60-81岁）的历史。验证性因素分析（CFA）支持CG分离和创伤性苦恼的双因素模型。为了研究CG和PTSD之间的关系，使用CFA指定和估计三个组合模型。一个模型，其中所有五个因素，CG的两个因素和PTSD的三个因素，如DSM-IV所定义的，允许相关提供最佳拟合。结果表明，CG和PTSD的维度之间有相当大的重叠，复杂的悲伤似乎在很大程度上是由PTSD的侵入性成分造成的。(C)2010爱思唯尔有限公司保留所有权利。
The aim of this study was to assess the factorial structure of complicated grief (CG) and investigate the relationship between CG and posttraumatic stress disorder (PTSD) through the assessment of models combining both constructs. The questionnaire was completed by elderly, married respondents with a history of at least one significant, interpersonal loss (145 males and 147 females, 60-81 years). Confirmatory factor analysis (CFA) supported a two-factor model of separation and traumatic distress in CG. To investigate the relationship between CG and PTSD three combined models were specified and estimated using CFA. A model where all five factors, the two factors of CG and the three factors of PTSD, as defined by the DSM-IV, were allowed to correlate provided the best fit. The results indicated a considerable overlap between the dimensions of CG and PTSD, and complicated grief is construct that appears to be largely accounted for by especially the intrusive component of PTSD.
