Although the initiation of cigarette use typically occurs prior to age 18, there is evidence for considerable change in smoking behavior after this age. College may be a particularly important period to study smoking because it is a time when adolescents transition into a new social context where substance use is normative. Using a longitudinal design, daily assessments of smoking were collected during the entire first year of college for a large cohort of freshman (N=496). Findings suggested a weekly cycle of smoking such that the probability of smoking was much higher on weekends (Friday and Saturday) than on remaining days of the week. In addition to this weekly cycle, there was an overall trend for smoking to decline over the course of the year. Substantial individual variability in levels of smoking was observed. These findings provide new insights into college smoking, and have implications for assessment, policy, intervention, and future directions for research.
尽管开始吸烟通常发生在18岁之前，但有证据表明，18岁之后吸烟行为会发生相当大的变化。大学时期可能是研究吸烟行为的一个特别重要的阶段，因为这是青少年过渡到一个新的社会环境的时期，在这个环境中物质使用是常态。采用纵向设计，对一大群大一新生（N = 496）在大学第一年全年进行吸烟情况的每日评估。研究结果表明吸烟呈现每周的循环模式，即周末（周五和周六）吸烟的可能性比一周中的其他日子要高得多。除了这种每周的循环模式外，全年吸烟率总体呈下降趋势。观察到吸烟水平存在很大的个体差异。这些发现为大学生吸烟问题提供了新的见解，并对评估、政策、干预措施以及未来的研究方向具有启示意义。
