|While the association between alcohol use and aggression is well documented, Eew studies have examined the relationship among youth developmentally. This study utilizes yearly data from a cohort of 808 male and female adolescents. The sample is from the longitudinal panel of the Seattle Social Development Project, which in 1985 sampled 5th grade students from high crime neighborhoods in Seattle, Washington. Yearly surveys were administrated from 8th to 12th grades except 11th grade. Both alcohol use and aggression were measured by multiple indicators in each of the four waves. With stability effects (from earlier alcohoL use to later alcohol use, and from earlier aggression to later'aggression) and cross-sectional correlation* controlled, we examine the cross-lagged effects from alcohol to aggression as well as those from aggression to alcohol. Structural Equation Modeling (LGM) was used to examine the fit of the model to the data. We conclude that the cross-lagged effects are evident in late adolescence, and mostly from aggression to alcohol use. separate models for males and females are also analyzed.
