This study focused on a group of Chinese adolescents and examined whether the degree of alexithymia would mediate the effect of PTSD from past trauma onto psychiatric co-morbidities and whether gender differences would moderate the mediational effects of alexithymia. Three hundred and twenty-six adolescents were recruited from two schools and completed the Posttraumatic Stress Diagnostic Scale, General Health Questionnaire-28 and Toronto Alexithymia Scale-20. The results showed that 54 % had no trauma in their lives; 10, 21 and 15 % met the criteria for full, partial and no-PTSD respectively. After adjusting the number of traumatic events, difficulty identifying feelings mediated the path between PTSD from past trauma and psychiatric co-morbidity. Gender moderated the mediational effect of difficulty identifying feelings. To conclude, adolescents can develop PTSD symptoms and psychiatric co-morbidity following exposure to a traumatic event. For both males and females, difficulty getting in touch with feelings can influence the impact of PTSD onto psychiatric co-morbidity.
本研究聚焦于一组中国青少年，探讨述情障碍程度是否会介导既往创伤所致创伤后应激障碍（PTSD）对精神共病的影响，以及性别差异是否会调节述情障碍的中介作用。从两所学校招募了326名青少年，他们完成了创伤后应激诊断量表、一般健康问卷-28和多伦多述情障碍量表-20。结果显示，54%的青少年生活中无创伤经历；10%、21%和15%的青少年分别符合完全、部分和无PTSD的标准。在调整创伤事件数量后，识别情感困难介导了既往创伤所致PTSD与精神共病之间的路径。性别调节了识别情感困难的中介作用。总之，青少年在经历创伤事件后可能会出现PTSD症状和精神共病。对于男性和女性而言，接触情感困难都会影响PTSD对精神共病的影响。
