About 22% of adult smokers in the U.S. are intermittent cigarette smokers (ITS). ITS can be further classified as native ITS who never smoked daily and converted ITS who formerly smoked daily but reduced to intermittent smoking. Ecological momentary assessment (EMA) was conducted to determine the behaviors and experiences that are associated with the decision to smoke.
The study included 24 native ITS and 36 converted ITS (N = 60) from the Pennsylvania Adult Smoking Study. A baseline questionnaire, daily log, and an EMA smoking log that assessed emotions, activities, and smoking urges was filled out with each cigarette for 1 week to capture 574 smoking sessions.
Both groups had very low levels of cigarette dependence. Both groups were more tempted to smoke in positive or negative situations than situations associated with habituation. EMA showed that the most common emotional state during smoking sessions was positive (47%), followed by negative (32%), neutral (16%), and mixed (5%) emotions. Smokers were more likely to smoke during activities of leisure (48%) than during performative duties (29%), social (16%) or interactive occasions (7%). Converted ITS were more likely to smoke alone compared to native ITS (p < .001).
ITS report minimal levels of dependence when captured on traditional scales of nicotine dependence, yet experience loss of autonomy and difficulty quitting. The majority of the ITS reported positive emotions and leisure activities while smoking, and smoked during the evening.
The current paper identifies environmental and behavioral factors that are associated with smoking among ITS in real time. (Am J Addict 2018;27:131-138).
美国约有 22%的成年吸烟者为间歇性吸烟者(ITS)。ITS 可进一步分为从未每日吸烟的原生 ITS 和从前每日吸烟但转为间歇性吸烟的转化 ITS。本研究通过使用生态瞬时评估(EMA)来确定与吸烟决策相关的行为和体验。
本研究纳入了宾夕法尼亚州成人吸烟研究中的 24 名原生 ITS 和 36 名转化 ITS(共 60 名)。参与者填写了基线问卷、每日日志和 EMA 吸烟日志,该日志评估了情绪、活动和吸烟冲动,在一周内每支烟都要填写,以捕获 574 次吸烟行为。
两组的吸烟依赖程度都非常低。两组在积极或消极情况下吸烟的冲动都高于在习惯化相关情况下的冲动。EMA 显示,在吸烟期间最常见的情绪状态是积极(47%),其次是消极(32%)、中性(16%)和混合(5%)情绪。吸烟者更有可能在休闲活动(48%)中吸烟,而不是在执行任务(29%)、社交(16%)或互动场合(7%)中吸烟。与原生 ITS 相比,转化 ITS 更有可能独自吸烟(p<0.001)。
当使用尼古丁依赖的传统量表来评估时,ITS 报告的依赖程度较低,但体验到自主丧失和戒烟困难。大多数 ITS 在吸烟时报告了积极的情绪和休闲活动,且在晚上吸烟。
本研究实时识别了与 ITS 吸烟相关的环境和行为因素。
