Compulsive buying is associated with significant psychiatric comorbidity, such as personality disorders. Few studies have focused on the dimensional model of personality disorders in compulsive buying. We aimed to assess the eventual presence of personality dysfunctions in compulsive buying according to the Diagnostic and Statistical Manual of Mental Disorder, 5th edition (DSM-5) dimensional conception of personality disorders. We screened online compulsive buying (QABB), characterized purchasing behavior and explored DSM-5 personality trait domains (Personality Inventory for DSM-5-Brief Form [PID-5-BF]) in 233 Paris psychology students using an online self-reporting questionnaire. The prevalence of compulsive buying among students was 7.7% (n = 18). The favorite items purchased by compulsive buyers were clothing and cosmetic products. Three mean trait domain scores were significantly higher for CB+ than CB- students: negative affect, detachment and disinhibition. Our findings suggest that compulsive buyers distinctively feature pathological DSM-5 dimensional personality trait domains.
强迫性购买与显著的精神共病有关，如人格障碍。很少有研究关注强迫性购买中的人格障碍多维模型。我们旨在根据精神障碍诊断与统计手册第 5 版（DSM-5）的人格障碍维度概念，评估强迫性购买中人格功能障碍的存在情况。我们使用在线自我报告问卷，对 233 名巴黎心理学学生进行了在线强迫性购买（QABB）筛查，描述了购买行为，并探讨了 DSM-5 人格特质领域（DSM-5 人格量表简短形式 [PID-5-BF]）。学生中强迫性购买的患病率为 7.7%（n=18）。强迫性购买者最喜欢购买的物品是服装和化妆品。3 项特质域评分均值在 CB+学生中显著高于 CB-学生：负性情绪、脱抑制和分离。我们的研究结果表明，强迫性购买者具有独特的病理性 DSM-5 维度人格特质领域。
