The current study (n=340 college students) examined individual differences in affective functioning among daily tobacco users, occasional users, and non-users. Tobacco use frequency in the past 6 months was positively associated with negative affect, affect lability, and rising reactivity while negatively associated with positive affect and falling reactivity. Multinomial logit analysis indicated that affect lability was positively associated with the likelihood of being either a non-user or a daily user relative to an occasional user. Positive affect and falling reactivity were positively associated and rising reactivity negatively associated with the likelihood of being a non-user relative to a daily user. The results indicate that daily tobacco use is associated with multiple indices of dysregulated affect. Daily tobacco use is associated with increased reactivity and decreased emotional stability coupled with decreased positive affect and a slowed rate of returning to baseline once aroused. Greater affect lability emerged as the primary affective difference between daily and occasional users.
当前的研究（n = 340名大学生）考察了每日吸烟者、偶尔吸烟者和不吸烟者在情感功能方面的个体差异。过去6个月的吸烟频率与消极情绪、情绪易变性和反应性增强呈正相关，而与积极情绪和反应性降低呈负相关。多项逻辑回归分析表明，相对于偶尔吸烟者，情绪易变性与成为不吸烟者或每日吸烟者的可能性呈正相关。积极情绪和反应性降低与相对于每日吸烟者成为不吸烟者的可能性呈正相关，而反应性增强与该可能性呈负相关。结果表明，每日吸烟与情感失调的多个指标相关。每日吸烟与反应性增加、情绪稳定性降低、积极情绪减少以及一旦被唤起后恢复到基线的速度减慢有关。更大的情绪易变性成为每日吸烟者和偶尔吸烟者之间主要的情感差异。
