Note.
Int = Intercept, Slp = Slope, WM = Working Memory, SS = Sensation Seeking, AWT = Acting Without Thinking, DD = Delay Discounting, AU = Alcohol Use frequency.
White was the reference category for Race-Ethnicity covariate. All continuous covariates are scored such that higher scores imply higher values on that variable.
