Given the well-established associations of the personality traits alexithymia, impulsivity, and reward sensitivity with problematic use of a variety of substances, including alcohol and cannabis, the present study sought to determine whether daily tobacco smoking is similarly linked to these traits. Male and female adults aged 18 to 40 years were recruited from the local Australian community, allowing comparison of demographically similar samples of current daily smokers (n = 47) to never-smokers (n = 59) on the relevant self-report measures. Multivariate analysis of covariance revealed that current smokers scored significantly higher than never-smokers on indices of negative mood, impulsiveness, and risky alcohol use, after controlling for social desirability. No significant group differences were found on indices of alexithymia, reward sensitivity, or punishment sensitivity. Results suggest that chronic daily cigarette smoking may be an exception to the maladaptive behaviors associated with alexithymia, and is driven primarily by mood regulation and poor impulse control.
鉴于人格特质的非言语性、冲动性和奖励敏感性与各种物质的使用问题，包括酒精和大麻，本研究旨在确定每日吸烟是否与这些特质有关。从当地澳大利亚社区招募了年龄在 18 至 40 岁的男性和女性成年人，使目前每日吸烟（n=47）和从不吸烟（n=59）的样本在相关的自我报告测量中具有相似的人口统计学特征。协方差的多变量分析显示，在控制了社会期望之后，当前吸烟者在消极情绪、冲动和危险饮酒方面的得分显著高于从不吸烟者。在述情障碍、奖励敏感性或惩罚敏感性方面没有发现显著的群体差异。结果表明，慢性每日吸烟可能是与述情障碍相关的适应不良行为的例外，主要是由情绪调节和冲动控制不良驱动的。
