Cluster B personality disorders (PDs) (i.e., antisocial, borderline, histrionic, and narcissistic) typically show a high degree of comorbidity with substance use disorders (SUDs). Previous research suggests that the broad-based personality domains of Disinhibition and Negative Temperament/Neuroticism may be common factors to both types of disorders. Using a two-phase process (i.e., screening and follow-up), this study examined three lower-order personality traits (i.e., dependency, impulsivity, and self-harm) that fall within the Disinhibition and Neuroticism domains. The study evaluated the hypotheses that these traits (a) are related both to cluster B PDs and to SUDs; and (b) underlie the association between the two types of disorders. Results indicate that impulsivity and self-harm play a significant role in cluster B PDs and SUDs, as well as in their association with each other. However, dependency was not associated with either type of disorder. These results indicate that sets of individual traits can be of significant utility in understanding the comorbidity between PDs and SUDs.
B类人格障碍（即反社会型、边缘型、表演型和自恋型人格障碍）通常与物质使用障碍（SUDs）高度共病。先前的研究表明，脱抑制和负性气质/神经质这两个人格领域可能是这两种障碍的共同因素。本研究采用两阶段过程（即筛查和随访），考察了脱抑制和神经质领域内的三种低阶人格特质（即依赖、冲动和自我伤害）。该研究评估了以下假设：这些特质（a）与B类人格障碍和物质使用障碍均相关；（b）是这两种障碍之间关联的基础。结果表明，冲动和自我伤害在B类人格障碍和物质使用障碍及其相互关联中起重要作用。然而，依赖与这两种障碍均无关联。这些结果表明，个体特质集在理解人格障碍和物质使用障碍之间的共病方面具有重要作用。
