Previous research repeatedly observed associations between academic achievement and substance use during adolescence. However, the simple frequency of substance use was not differentiated from the emergence of substance use related problems, such as abuse and dependence. This study presents autoregressive cross-lagged models describing inter-relations between academic achievement, frequency of substance use, and substance use related problems among a sample of 1034 seventh graders (46% female; 83% White North Americans; Mage = 12.64 years, SD = 0.65) who participated in a four-year longitudinal study. The stability of measurement structure of frequency of substance use and substance use related problems was supported. Higher frequency of substance use and substance use related problems did not predict lower academic achievement. A higher academic achievement predicted a later increase in frequency of substance use and substance use related problems in boys, whereas a higher academic achievement predicted a lower frequency of substance use in girls. Although substance use related problems were mainly predicted by frequency of substance use, substance use can remain, nonetheless, non-problematic during adolescence.
先前的研究反复观察到青少年时期学业成绩和物质使用之间的关联。然而，物质使用的简单频率并没有从物质使用相关问题（如滥用和依赖）的出现中区分出来。本研究提出了自回归交叉滞后模型，描述了在一个由 1034 名七年级学生（46%为女性；83%为白种北美洲人；平均年龄为 12.64 岁，标准差为 0.65）组成的样本中，学业成绩、物质使用频率和物质使用相关问题之间的相互关系，这些学生参与了一项为期四年的纵向研究。物质使用频率和物质使用相关问题的测量结构稳定性得到了支持。较高的物质使用频率和物质使用相关问题并不能预测较低的学业成绩。较高的学业成绩预测男孩物质使用频率和物质使用相关问题的后期增加，而较高的学业成绩预测女孩物质使用频率的降低。尽管物质使用相关问题主要由物质使用频率预测，但在青少年时期，物质使用仍然可以是非问题性的。
