Abstract

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, SDage?=?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.
