Notes.

Fixed effects for assessment month (December vs. September, February vs. September, April vs. September) and Year (0=year 1, 1=year 2, 2=year 3) were included at level 1 of the multilevel model, but parameter estimates for these covariates are not shown to help simplify the table.

The random slope is for the within-person associations of cannabis frequency and alcohol consumption with alcohol consequences. Because the values of the slopes vary across participants, the random slopes are estimated as a between-person latent variable with the mean representing the average within-person association and the variance representing the amount of variability in the slope across participants.

The random slope variance was fixed to zero to facilitate estimation.
