Although alcohol use disorders (AUDs) have been associated with different aspects of disinhibited personality and antisociality, less is known about the specific relationships among different domains of disinhibited personality, antisociality, alcohol use, and alcohol problems. The current study was designed to address three goals, (i) to provide evidence of a three-factor model of disinhibited personality (comprised of impulsivity [IMP], risk taking/low harm avoidance [RTHA], excitement seeking [ES]), (ii) to test hypotheses regarding the association between each dimension and alcohol use and problems, and (iii) to test the hypothesis that antisociality (social deviance proneness [SDP]) accounts for the direct association between IMP and alcohol problems, while ES is directly related to alcohol use. Measures of disinhibited personality IMP, RTHA, ES and SDP and alcohol use and problems were assessed in a sample of young adults (N=474), which included a high proportion of individuals with AUDs. Confirmatory factor analyses supported a three-factor model of disinhibited personality reflecting IMP, RTHA, and ES. A structural equation model (SEM) showed that IMP was specifically associated with alcohol problems, while ES was specifically associated with alcohol use. In a second SEM, SDP accounted for the majority of the variance in alcohol problems associated with IMP. The results suggest that aspects of IMP associated with SDP represent a direct vulnerability to alcohol problems. In addition, the results suggest that ES reflects a specific vulnerability to excessive alcohol use, which is then associated with alcohol problems, while RTHA is not specifically associated with alcohol use or problems when controlling for IMP and ES.
尽管酒精使用障碍（AUD）与抑制障碍和反社会行为的不同方面有关，但对于抑制障碍的不同领域、反社会性、酒精使用和酒精问题之间的具体关系知之甚少。本研究旨在实现三个目标：（i）提供抑制障碍人格的三因素模型的证据（由冲动性[IMP]、冒险/低回避风险[RTHA]、兴奋寻求[ES]组成）；（ii）检验每个维度与酒精使用和问题之间关联的假设；（iii）检验反社会性（社交偏差倾向[SDP]）解释 IMP 与酒精问题之间直接关联，而 ES 与酒精使用直接相关的假设。在一个包含大量 AUD 患者的年轻人样本中（N=474），评估了抑制障碍人格的冲动性、冒险/低回避风险、兴奋寻求和 SDP 以及酒精使用和问题的测量。验证性因素分析支持反映 IMP、RTHA 和 ES 的抑制障碍人格三因素模型。结构方程模型（SEM）表明，IMP 与酒精问题特别相关，而 ES 与酒精使用特别相关。在第二个 SEM 中，SDP 解释了与 IMP 相关的酒精问题的大部分方差。结果表明，与 SDP 相关的 IMP 方面代表了对酒精问题的直接易感性。此外，结果表明 ES 反映了对过度饮酒的特定易感性，然后与酒精问题相关，而在控制 IMP 和 ES 时，RTHA 与酒精使用或问题没有特别相关。
