To explore the role of personality traits in at-risk drinking and current cannabis use among medical students.
This cross-sectional study evaluated 707 medical students from two universities. Multiple logistic regression models for at-risk drinking and current cannabis use were constructed including sociodemographic, psychiatric, and personality variables.
At-risk drinking and current cannabis use were reported by 19.3% and 14.9% of participants, respectively. Models including Big Five measures showed associations of at-risk drinking with higher extraversion (p < 0.00001, adjusted odds ratio [AOR] = 1.9) and lower conscientiousness (p = 0.00001, AOR = 0.5); cannabis use was also associated with lower conscientiousness (p = 0.003, AOR = 0.6), besides higher openness to experience (p = 0.002, AOR = 1.9). Models including measures of the Behavioral Inhibition and Activation Systems scales (BIS/BAS) showed associations of at-risk drinking with lower BIS (p = 0.002, AOR = 0.9) and higher BAS fun-seeking (p = 0.0005, AOR = 1.2); cannabis use was also associated with higher BAS fun-seeking (p = 0.008, AOR = 1.2). Personality variables had modest effects on model fit.
Specific personality traits were independently associated with at-risk drinking and current cannabis use, albeit with modest effect sizes.
探讨人格特质在医学生高危饮酒和当前大麻使用中的作用。
本横断面研究评估了来自两所大学的 707 名医学生。构建了包括社会人口学、精神科和人格变量在内的高危饮酒和当前大麻使用的多变量逻辑回归模型。
分别有 19.3%和 14.9%的参与者报告存在高危饮酒和当前大麻使用。包括大五人格测试在内的模型显示，高危饮酒与较高的外向性（p<0.00001，调整后的优势比 [AOR] = 1.9）和较低的尽责性（p = 0.00001，AOR = 0.5）有关；大麻使用也与较低的尽责性（p = 0.003，AOR = 0.6）有关，除了较高的开放性经验（p = 0.002，AOR = 1.9）。包括行为抑制和激活系统量表（BIS/BAS）测量在内的模型显示，高危饮酒与较低的 BIS（p = 0.002，AOR = 0.9）和较高的 BAS 寻求乐趣（p = 0.0005，AOR = 1.2）有关；大麻使用也与较高的 BAS 寻求乐趣（p = 0.008，AOR = 1.2）有关。人格变量对模型拟合的影响较小。
特定的人格特质与高危饮酒和当前大麻使用独立相关，尽管效应大小适中。
