背景：本研究根据日本普通人群复杂悲伤的严重程度，探讨述情障碍与复杂悲伤的关系是否不同于述情障碍与一般抑郁症状的关系。方法：在日本普通人群样本中，948名年龄在40 ~ 79岁之间的参与者（有效有效率为48.0%）完成了关于述情障碍、抑郁和复杂悲伤的横断面匿名问卷。为了比较复杂悲伤组的高风险（n = 243）和低风险（n = 705），采用标准最大似然估计对两组进行同步分析，并对6个假设模型进行验证。结果：模型（RMSEA = 0.047, AIC = 71.520）表明述情潜变量与观察变量的通径系数相等，述情潜变量与心理困扰的通径系数相等。述情障碍对复杂悲伤的贡献率（2-4%）明显小于抑郁症（37-38%）。结论：与抑郁相比，述情障碍对复杂悲伤的贡献不大，且高危组述情障碍对复杂悲伤的贡献比例低于低危组。心理困扰潜变量对复杂悲伤和抑郁的贡献在高危组低于低危组。述情障碍和复杂悲伤之间缺乏相关性可能表明述情障碍和复杂悲伤的症状有不同的机制。(C) 2011 Elsevier B.V.版权所有
Background: The present research investigated whether the relationship between alexithymia and complicated grief was different from the relationship between alexithymia and general depressive symptom according to the seriousness of complicated grief in the Japanese general population.Methods: In the Japanese general population sample, 948 participants between 40 and 79 years old (effective response rate, 48.0%) completed a cross-sectional anonymous questionnaire about alexithymia, depression, and complicated grief. To compare the high risk (n = 243) and low risk (n = 705) of complicated grief groups, simultaneous analysis of two groups with standard maximum likelihood estimation was performed and six hypothesized models were verified.Results: The model (RMSEA = 0.047, AIC = 71.520) that showed that the path coefficients of the latent variable of alexithymia to the observed variables were equal and that the path coefficient of alexithymia to psychological distress was equal was adopted. The contribution ratios from alexithymia to complicated grief were apparently smaller (2-4%) than those to depression (37-38%).Conclusions: Our findings showed that alexithymia scarcely contributed to complicated grief compared to depression and that the contribution ratio in the high risk group was lower than that in the low risk group. The contribution of the latent variable of psychological distress to complicated grief and depression was lower in the high risk group than in the low risk group. The lack of a correlation between alexithymia and complicated grief might indicate that there are different mechanisms underlying the symptoms of alexithymia and complicated grief.
