The ; 5th ed.) reassignment of gambling disorder as an addictive disorder alongside the substance-related addictive disorders encourages research into their shared etiologies. The aims of this study were to examine: (a) the associations of Big Five personality dimensions with alcohol, nicotine, cannabis, and gambling disorders, (b) the comorbidity between these disorders, (c) the extent to which common personality underpinnings explain comorbidity, (d) whether results differed for men and women, and (e) the magnitude of personality differences corresponding to the 4 disorders. Participants were 3,785 twins and siblings (1,365 men, 2,420 women; M = 32 years, range = 21-46 years) from the Australian Twin Registry who completed psychiatric interviews and Big Five personality inventories. The personality profile of high neuroticism, low agreeableness, and low conscientiousness was associated with all 4 addictive disorders. All but 1 of the pairwise associations between the disorders were significant. After accounting for Big Five traits, the associations were attenuated to varying degrees but remained significant. The results were generally similar for men and women. The results suggest that the Big Five traits of neuroticism, agreeableness, and conscientiousness are associated with the general propensity to develop an addictive disorder and may in part explain their co-occurrence; however, they may be more broadly associated with the propensity for any psychiatric disorder. The effect sizes of the personality associations suggest that the diagnosis of gambling disorder as operationalized by the may be more severe than the other addictive disorders. Calibration of the diagnosis of gambling disorder to the other addictive disorders may be warranted. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
（第 5 版）将赌博障碍重新归类为与物质相关的成瘾障碍之一，鼓励对它们共同的病因进行研究。本研究的目的是检验：（a）大五人格维度与酒精、尼古丁、大麻和赌博障碍的关联，（b）这些障碍之间的共病，（c）共同人格基础解释共病的程度，（d）结果是否因男性和女性而异，以及（e）对应于 4 种障碍的人格差异的程度。参与者为来自澳大利亚双胞胎登记处的 3785 对双胞胎和兄弟姐妹（1365 名男性，2420 名女性；平均年龄 32 岁，范围为 21-46 岁），他们完成了精神病学访谈和大五人格量表。高神经质、低宜人性和低尽责性的人格特征与所有 4 种成瘾障碍有关。除了 1 种障碍外，所有障碍之间的两两关联均具有统计学意义。在考虑了大五特质后，关联程度有所减弱，但仍具有统计学意义。结果在男性和女性中基本相似。结果表明，神经质、宜人性和尽责性的大五特质与发展成瘾障碍的普遍倾向有关，可能在一定程度上解释了它们的共病；然而，它们可能与任何精神障碍的倾向更广泛相关。人格关联的效应大小表明，操作化定义的赌博障碍的诊断可能比其他成瘾障碍更严重。有必要对赌博障碍的诊断进行校准，使其与其他成瘾障碍相匹配。（PsycINFO 数据库记录（c）2019 APA，保留所有权利）。
