The aim of this study was to explore a longitudinal bi-directional relationship between school achievement and smoking behavior. The sample consists of 2,188 Finnish students in grades 7-9. Data were collected at three separate occasions between the years 1998 and 2000. Three hypothesized conceptual models were developed and tested using path analyses by structural equation modeling (SEM). Students that performed poorly at school smoked weekly six times more than those who achieved the highest school grade point averages at the age of 15. Using SEM, the findings suggest that not only does deterioration of school achievement contribute to progression in smoking uptake continuum but also vice versa progression in smoking uptake continuum to deterioration of school achievement over time (CFI = .997). There were no moderating effects of gender or treatment condition in the proposed models. Both deterioration of school achievement and progression in smoking uptake continuum predicted changes in other behavior during the first two years in secondary school in Finland.
本研究旨在探索学业成绩和吸烟行为之间的纵向双向关系。样本包括芬兰 7-9 年级的 2188 名学生。数据在 1998 年至 2000 年的三个不同时间点收集。通过结构方程建模（SEM）的路径分析，开发并测试了三个假设的概念模型。在 15 岁时，学业成绩较差的学生每周吸烟的频率是成绩最高的学生的六倍。使用 SEM 的研究结果表明，不仅学业成绩的恶化会导致吸烟量增加的连续体的进展，而且相反，随着时间的推移，吸烟量增加的连续体的进展也会导致学业成绩的恶化（CFI =.997）。在所提出的模型中，性别或治疗条件没有调节作用。在芬兰的中学头两年，学业成绩的恶化和吸烟量增加的连续体的进展都预测了其他行为的变化。
