Abstract
Latent growth modeling was used to test dynamic relations between self-esteem and alcohol use in 740 middle school youth assessed at four time points. Self-esteem was characterized by a negative growth trajectory, whereas alcohol use increased steadily in a linear fashion. An initial simplified model positing bidirectional influences indicated an inverse relation between changes in self-esteem and alcohol use over time, but that initial levels of neither alcohol use nor self-esteem influenced changes in the other construct. With the addition of external covariates (i.e., gender and indices of social skills and competence risk), findings indicated that high initial levels of self-esteem fostered more increases in alcohol use compared to low initial levels of self-esteem. Findings further indicated that youth with poor competence skills advanced more rapidly in their alcohol use and declined more gradually in their self-esteem, and that poor social skills accelerated the rate of decline in self-esteem. Results indicate that self-esteem is part of a dynamic set of etiological forces that instigate early-stage alcohol use.
