自我怜悯在抑郁症患者述情障碍与抑郁症状间的中介作用

  目的  评估抑郁症患者自我怜悯、述情障碍和抑郁症状，探讨自我怜悯在述情障碍和抑郁症状的中介作用。  方法  采用中文版自我怜悯量表(self-compassion scale, SCS-C)和中文版多伦多述情障碍量表(Toronto alexithymia scale, TAS-20)对117例抑郁症患者和106例健康对照组作评估，同时患者接受中文版贝克抑郁自评量表(Beck depression rating scale, BDI)评估。选用线性回归分析模型对抑郁症患者自我怜悯、述情障碍和抑郁症状以及各维度之间的关系进行分析，使用AOMS 23.0软件进行中介效应检验。  结果  抑郁症患者组SCS-C总分及三因子分均低于对照组(均有P < 0.05)，患者组TAS-20总分及三因子分均高于对照组(均有P < 0.05)；相关分析显示，患者SCS-C总分及各因子分、TAS-20总分及各因子分和抑郁症状分间均两两相关(均有P < 0.05)；回归分析模型发现:述情障碍及各因子对自我怜悯有负性预测作用；自我怜悯及各因子对抑郁症状有负性预测作用；述情障碍及各因子对抑郁症状有正性预测作用。自我怜悯在述情障碍与抑郁症状间起着部分中介作用。  结论  抑郁症患者存在自我怜悯损害和述情障碍，述情障碍通过自我怜悯水平的部分中介效应对抑郁症状产生影响。提高抑郁症患者的自我怜悯水平可能是改善抑郁症状的干预措施之一。

The mediating effect of self-compassion between alexithymia and depressive symptoms in depression patients

  Objective  To assess the self-compassion, alexithymia and depressive symptoms in patients with depression, and to explore the mediating effects of self-compassion between alexithymia and depressive symptoms.  Methods  117 depression patients and 106 healthy subjects were measured using the Chinese version of revised self-compassion scale (SCS-C), the Chinese version of Toronto alexithymia scale (TAS-20). The patients were also assessed with the Chinese version of Beck depression rating scale (BDI), Linear regression analysis model was used to analyze the relationship between self-compassion, alexithymia, depressive symptoms and its dimensions. The mediating effect was tested with AOMS 23.0 software.  Results  Compared with the healthy controls, depressive patients had significantly lower SCS-C total score and the scores of three factors (all P < 0.05). Patients had significantly higher TAS-20 total score and the scores of three factors Compared to healthy controls (all P < 0.05). Correlation analysis model showed in the patients' group, there were significant correlation between SCS-C total score and three subscale score, the total score of TAS-20 and three subscale score and the score of depression symptoms. Regression analysis model showed that alexithymia and the three factors had negative predictive effect on self-compassion; self-compassion and the three factors had negative predictive effect on depressive symptoms; alexithymia and the three factors had positive predictive effect on depressive symptoms. Part of mediator effect of self-compassion was significant between alexithymia and depressive symptoms level.  Conclusions  Depression patients have impairments of self-compassion and alexithymia, and self-compassion is a part of mediator by which alexithymia influence depressive symptoms. Improving the depression patient's level of self-compassion may be one of the interventions to improve depressive symptoms in clinical practice.
