Psychopathy and borderline personality disorder (BPD) are commonly associated with an increased propensity toward substance use. However, few studies have accounted for shared variance between psychopathy and BPD when examining relationships with unique forms of substance use, particularly in justice-involved females. This study investigated psychopathic and BPD traits in relation to alcohol and drug use in a sample of 274 incarcerated adult females. Results revealed that psychopathic and BPD traits were differentially related to alcohol and drug use. Specifically, unique variance in BPD traits was related to alcohol use, whereas unique variance in lifestyle-antisocial psychopathic traits was related to drug use. Findings support unique relationships between psychopathic and BPD traits and problematic and prolonged alcohol and drug use in incarcerated adult females. Results may inform methods of tailoring specific substance use treatments for use in females with distinct personality profiles.

精神病和边缘性人格障碍 (BPD) 通常与物质使用倾向增加有关。然而，在研究与独特的物质使用形式的关系时，特别是在涉及正义的女性中，很少有研究解释精神病态和边缘性人格障碍之间的共同差异。这项研究以 274 名被监禁的成年女性为样本，调查了与酒精和毒品使用相关的精神病和 BPD 特征。结果显示，精神变态和边缘性人格障碍特征与酒精和药物使用存在不同的相关性。具体来说，边缘性人格障碍特征的独特变异与饮酒有关，而生活方式-反社会精神病特征的独特变异与吸毒有关。研究结果支持精神病态和边缘性人格障碍特征与被监禁的成年女性有问题且长期酗酒和吸毒之间的独特关系。结果可能会为针对具有不同性格特征的女性定制特定药物使用治疗的方法提供信息。
