摘要：

目的 探讨服刑人员童年创伤与自杀风险的关系，以及述情障碍的中介效应。方法 采用童年创伤问卷（CTQ-SF）、述情障碍量表（TAS-20）、自杀行为问卷（SBQ-R）对广东省某所监狱362名男性服刑人员进行调查。结果（1）有35名服刑人员有高自杀风险，占调查人数的9.7%；（2）童年创伤问卷总分及各个维度得分与自杀行为问卷总分呈显著正相关（r=0.065~0.358，P<0.01）；（3）除性虐待维度外，童年创伤问卷各维度得分均与述情障碍量表总分呈显著正相关（r=0.156~0.255，P<0.01）；（4）述情障碍量表总分与自杀行为问卷总分呈显著正相关（r=0.330，P<0.01），述情障碍量表的情感辨别不能和情感描述不能维度与自杀行为问卷总分呈显著正相关（r=0.294~0.305，P<0.01），述情障碍的外向性思维与自杀行为问卷总分呈正相关（r=0.130，P<0.05）；（5）述情障碍在童年创伤与自杀风险之间存在部分中介效应（β=0.07，95%CI：0.023~0.121，P<0.05），中介效应占总效应比例16.22%。结论 童年创伤既可以直接影响服刑人员的自杀风险，也可以通过述情障碍的中介效应间接影响自杀风险。

Abstract:

Objective To explore the relationship between childhood trauma and suicidal risk in prisoners and the mediating effect of alexithymia in this relationship. Method We investigated a total of 362 male prisoners in Guangdong Province using Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Twenty-item Toronto Alexithymia Scale (TAS-20) and Suicidal Behaviors-Revised Questionnaire (SBQ-R). Results Thirty-five (9.7%) prisoners had a high risk of suicide. The total score and the dimension scores of the CTQ-SF was positively correlated with the total score of SBQ-R (r=0.065-0.358, P<0.01) and the total score of TAS-20 (except for the dimension score of sexual abuse) (r=0.156-0.255, P<0.01). The total score of TAS-20, the dimensions scores for difficulty in identifying and describing feeling and the dimension score for externally oriented thinking were positively correlated with the total score of SBQ-R (r=0.330, P<0.01; r=0.294-0.305, P<0.01; and r=0.130, P<0.05, respectively). The results of structural equation analysis showed that alexithymia had a partial mediating effect on childhood trauma and suicide risks (β=0.07, 95%CI: 0.023-0.121, P<0.05). Conclusion Childhood trauma affects suicidal risk in prisoners not only directly but also indirectly through the mediating effect of alexithymia.
