述情障碍在男性服刑人员特质愤怒与攻击行为间的中介作用

The mediating role of alexithymia in the relationship between trait anger and aggressive behavior among male prisoners

目的探讨述情障碍及其因子在特质愤怒与男性暴力犯罪服刑人员攻击行为之间的中介作用。方法采用特质愤怒量表(the trait anger scale,TAS)、多伦多述情障碍量表(Toronto alexithymia scale-20,TAS-20)和中文大学生版Buss-Perry攻击性量表(the Chinese college students' version of Buss-Perry aggression questionnaire)对268名男性暴力犯罪服刑人员进行施测,使用SPSS 23.0和Mplus 8.0进行中介效应检验。结果特质愤怒、攻击行为和述情障碍的总分分别为(17.75±4.93)分、(52.15±10.61)分、(70.90±19.40)分。Pearson相关分析表明,特质愤怒与攻击行为(r=0.67,P<0.01)、述情障碍(r=0.40,P<0.01)均呈正相关,述情障碍与攻击行为也呈正相关(r=0.55,P<0.01)。多元层次回归分析表明,在控制酒精成瘾的影响后,特质愤怒对攻击行为的直接预测作用显著(β=0.67,P<0.01);述情障碍的情感辨认障碍因子在特质愤怒与攻击行为之间起部分中介作用(β=0.18,95%CI=0.11~0.27)。结论特质愤怒不仅可以直接影响男性暴力犯罪服刑人员攻击行为,也可以通过述情障碍中的情感辨认障碍因子间接影响男性暴力犯罪服刑人员攻击行为。

Objective To explore the mediating role of alexithymia in the relationship between trait anger and aggressive behavior among male violent prisoners.Methods A sample of 268 male violent prisoners completed self-report measures of the trait anger scale(TAS),Toronto alexithymia scale-20(TAS-20)and the Chinese college students'version of Buss-Perry aggression questionnaire.SPSS 23.0 software and Mplus 8.0 software were used to test the mediating effect.Results The total scores of trait anger,aggressive behavior and alexithymia were(17.75±4.93),(52.15±10.61)and(70.90±19.40),respectively.Pearson correlation analysis showed that trait anger was both significantly positively correlated with aggressive behavior(r=0.67,P<0.01)and alexithymia(r=0.40,P<0.01),and there was also a significantly positive correlation between alexithymia and aggressive behavior(r=0.55,P<0.01).Multivariate hierarchical regression analysis showed that trait anger directly predicted aggressive behavior(β=0.67,P<0.01)after controlling the influence of alcohol addiction.Emotional recognition disorder played a partially mediating role in the relationship between trait anger and aggressive behavior(β=0.18,95%CI=0.11-0.27).Conclusion Trait anger not only directly affects male violent prisoners aggressive behavior,but also indirectly affects male violent prisoners aggressive behavior through emotional recognition disorder.
