College is a time when individuals are at risk for initiating or increasing their smoking behavior. Little is known, however, about the contexts in which college students smoke. Identifying antecedents to smoking would provide insights into motivation and stimulus control of smoking in this population.
In a sample of 50 college student smokers, situational, behavioral, and subjective state variables were compared between prompted interviews (N = 2,095) and participant-initiated smoking interviews (N = 865) using electronic handheld diaries.
The strongest predictors of smoking were recently inhabiting an outside location (odds ratio [OR] = 4.19, p < .001), the presence of others smoking (OR = 3.93, p < .001), and being where smoking was permitted (OR = 3.26, p < .001), indicating situational control over smoking. Less cue control over smoking was found for daily than nondaily smokers. Craving was the most robust subjective antecedent of smoking behavior (OR = 1.32, p < .001).
These results suggest that smoking among college students is largely opportunistic, craving is important and may develop early in the progression of smoking, and stimulus control may erode with greater smoking experience.
大学阶段是个人开始或增加吸烟行为的风险期。然而，人们对大学生吸烟的情境知之甚少。了解吸烟的前因可以深入了解这一人群吸烟的动机和刺激控制。
在 50 名大学生吸烟者的样本中，使用电子手持日记比较了提示访谈（N = 2095）和参与者发起的吸烟访谈（N = 865）之间的情境、行为和主观状态变量。
吸烟的最强预测因素是最近居住在室外（优势比[OR] = 4.19，p <.001）、他人吸烟（OR = 3.93，p <.001）和允许吸烟的地方（OR = 3.26，p <.001），表明对吸烟有情境控制。与非日常吸烟者相比，日常吸烟者对吸烟的线索控制较少。渴望是吸烟行为最有力的主观前兆（OR = 1.32，p <.001）。
这些结果表明，大学生吸烟主要是机会主义的，渴望很重要，并且可能在吸烟的早期阶段就出现了，并且随着吸烟经验的增加，刺激控制可能会减弱。
