The authors examined competing hypotheses regarding the role of 2 personality dimensions, disconstraint and negative emotionality, in mediating the relationship between posttraumatic stress disorder (PTSD) severity and substance-related problems. Data were drawn from a large sample of male Vietnam veterans. The best-fitting structural model included significant indirect paths from PTSD to both alcohol- and drug-related outcomes through disconstraint, and a significant indirect path from PTSD to alcohol-related problems through negative emotionality. There were no direct effects of PTSD on either substance-related outcome. These findings indicate distinct pathways to different forms of substance-related problems in PTSD and underscore the role of personality in mediating these relationships.
作者研究了关于两种人格维度（放纵和负性情绪）在介导创伤后应激障碍（PTSD）严重程度与物质相关问题之间关系时的相互竞争的假设。数据来自一大群越南战争退伍军人男性样本。最佳拟合结构模型包括从PTSD通过放纵到酒精和药物相关结果的显著间接路径，以及从PTSD通过负性情绪到酒精相关问题的显著间接路径。PTSD对任何一种物质相关结果均无直接影响。这些发现表明PTSD中不同形式的物质相关问题有不同的途径，并强调了人格在介导这些关系中的作用。
