Unadjusted and adjusted differences in mean acute problem severity by location and age. Error bars show standard errors. Unadjusted estimates (a) were derived from the simple regression of acute alcohol problem severity on location, age, and their interaction. Means in the middle graph (b) were derived from models that additionally adjusted for the effect of bar attendance on acute alcohol problem severity. The final graph (c) shows means implied by the baseline mediation model, which adjusted for effects of both bar attendance and drinking on acute alcohol problem severity. In the unadjusted model, border young adults reported significantly higher acute alcohol problem severity than older border residents (b = .41, SE=.18, p<.05); other comparisons were nonsignificant. Acute alcohol problems is a latent variable scaled in a standard deviation metric, where the reference group (non-border residents aged 30+) intercept/mean is defined as zero.
