Posttraumatic stress disorder (PTSD) and alcohol misuse, which frequently co-occur among combat veterans, have been linked to emotion dysregulation. Emotion dysregulation may explain the link between PTSD and alcohol misuse, and this investigation tested emotion dysregulation as a mediator of that relationship.
Correlations between PTSD symptoms and cluster symptoms, emotion dysregulation full and subscales, and alcohol misuse were examined in a sample of 139 combat Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn veterans (45% African American; 89% men). Emotion dysregulation full scale and subscales were examined as mediators of the relationship between PTSD symptoms and alcohol misuse for the full sample and men only.
PTSD symptoms and symptom clusters, emotion dysregulation, and alcohol misuse showed positive correlations for the full sample and men only. Neither the full scale of emotion dysregulation nor the facets of emotion dysregulation mediated the relationship between PTSD symptoms and alcohol misuse for the full sample; among men, the Impulse Control Difficulties when Upset and Lack of Emotional Clarity subscales were mediators of that relationship.
Impulse control difficulties and lack of emotional clarity may play an important role in the link between PTSD and alcohol misuse for male veterans and should be an important target in treatment for individuals with both disorders. Addressing impulse control difficulties and lack of emotional clarity in those with PTSD and alcohol misuse may improve outcomes by helping individuals identify and describe upsetting emotions and develop healthy coping alternatives to alcohol misuse.
创伤后应激障碍（PTSD）和酒精滥用在退伍军人中经常同时出现，它们与情绪调节障碍有关。情绪调节障碍可能解释了PTSD与酒精滥用之间的联系，本研究检验了情绪调节障碍作为这种关系的中介因素。
在139名持久自由行动/伊拉克自由行动/新黎明行动退伍军人样本中（45%为非裔美国人；89%为男性），研究了PTSD症状与集群症状、情绪调节障碍总分及分量表、以及酒精滥用之间的相关性。对整个样本和仅男性样本，检验了情绪调节障碍总分及分量表作为PTSD症状与酒精滥用之间关系的中介因素。
PTSD症状与症状集群、情绪调节障碍、以及酒精滥用在整个样本和仅男性样本中呈正相关。情绪调节障碍总分及情绪调节障碍的各个方面均未介导整个样本中PTSD症状与酒精滥用之间的关系；在男性中，心烦意乱时的冲动控制困难和情绪清晰度缺乏分量表是这种关系的中介因素。
冲动控制困难和情绪清晰度缺乏可能在男性退伍军人PTSD与酒精滥用之间的联系中起重要作用，并且应该成为患有这两种障碍的个体治疗的重要靶点。解决PTSD和酒精滥用患者的冲动控制困难和情绪清晰度缺乏问题，可能通过帮助个体识别和描述令人心烦的情绪，并开发出替代酒精滥用的健康应对方式来改善治疗效果。
