Cigarette use among young adults continues to rise. As young adults transition to college and assume other adult roles and responsibilities, they are at risk for the development of mental health problems and for the progression of substance use problems. Previous studies suggest that individual differences in negative and positive mood contribute to cigarette use in established college-aged smokers, but less is known whether fluctuations in mood influence daily cigarette use, controlling for trait levels of internalizing symptoms and nicotine dependence.
Data for this study came from a sample of college students (N=39, 59% female, mean age 20.4years) who reported regular cigarette use and participated in a 21-day ecological momentary assessment (EMA) study assessing within-individual variation in cigarette use and mood.
A three-level hierarchical linear model accounting for the structure of 1896 occasions of cigarette use nested within days and individuals indicated that within-individual variability in positive mood was associated with cigarette use at each occasion, after taking into account baseline levels of nicotine dependence and internalizing problems.
Daily shifts in positive moods are importantly associated with consuming cigarettes throughout the day.
年轻人吸烟的现象仍在持续上升。随着年轻人步入大学并开始承担其他成年人的角色和责任，他们面临着心理健康问题和物质使用问题发展的风险。先前的研究表明，消极和积极情绪的个体差异导致了已确立的大学生吸烟者吸烟，但对于情绪波动是否会影响日常吸烟，在控制内在症状和尼古丁依赖的特质水平的情况下，这方面的了解较少。
本研究的数据来自于一个大学生样本（N=39，女性占 59%，平均年龄 20.4 岁），他们报告了有规律的吸烟行为，并参与了一项为期 21 天的生态瞬时评估（EMA）研究，评估了吸烟和情绪的个体内变化。
一个考虑到个体内变异性的三级层次线性模型表明，在考虑到尼古丁依赖和内在问题的基线水平后，积极情绪的个体内变异性与每天吸烟的每个时刻有关。
积极情绪的日常变化与全天吸烟有重要关联。
