Smokers tend to smoke when experiencing craving, but even within smoking occasions, craving may vary. We examine variations in craving when people were smoking in various real-world situations.
Using Ecological Momentary Assessment, 394 smokers recorded smoking, craving, and smoking context in real time on electronic diaries over 2 weeks of ad libitum smoking. Assessments occurred immediately prior to smoking. Mixed modeling was used to analyze associations between craving and situational variables.
Craving varied across smoking situations, but the differences were small (<1 on a 0-10 scale). Specifically, craving was higher in smoking situations where smoking was restricted, likely because high craving leads smokers to violate restrictions. Controlling for restrictions, craving was higher when cigarettes were smoked while eating or drinking, were with other people (vs. alone), were in a group of people (vs. other people simply in view), during work (vs. leisure), and during activity (vs. inactivity). In addition, craving was higher for cigarettes smoked early in the day. No differences in craving were observed in relation to drinking alcohol or caffeine (vs. doing anything else), being at work (vs. home), being at a bar or restaurant (vs. all other locations), interacting with others (vs. not interacting), or other people smoking (vs. no others smoking).
Even though most craving reports prior to smoking were high, and situations were thus expected to have little influence on craving, results suggest that some cigarettes are craved more than others across different smoking situations, but differences are small.
吸烟者在有吸烟欲望时往往会吸烟,但即使在吸烟过程中,吸烟欲望也可能会有所不同。我们考察了人们在各种真实情况下吸烟时吸烟欲望的变化。
使用生态瞬间评估法,394 名吸烟者在 2 周的自由吸烟期间,通过电子日记实时记录吸烟、吸烟欲望和吸烟环境。评估是在吸烟前立即进行的。混合建模用于分析吸烟欲望和情境变量之间的关联。
吸烟情境不同,吸烟欲望也不同,但差异较小(0-10 分制上为 1 分以下)。具体而言,在吸烟受限的情况下,吸烟欲望更高,这可能是因为强烈的吸烟欲望会导致吸烟者违反限制。控制限制因素后,当吸烟者在进食或饮水时、与他人一起(而非独自)、在一群人当中(而非其他人仅仅在视野范围内)、在工作中(而非闲暇时)、在活动中(而非静止时)吸烟时,吸烟欲望更高。此外,在一天中较早的时候吸烟,吸烟欲望更高。在与饮酒或摄入咖啡因(而非做其他事情)、在工作场所(而非家中)、在酒吧或餐厅(而非其他所有地点)、与他人互动(而非不互动)或其他人吸烟(而非其他人不吸烟)有关时,吸烟欲望没有差异。
尽管大多数吸烟欲望报告在吸烟前较高,而且预计情况对吸烟欲望的影响较小,但结果表明,在不同的吸烟情况下,一些香烟比其他香烟更受渴望,但差异较小。
