Step 0: Unadjusted for confounders
Step 1: Adjusted for background confounders: financial difficulties, family education level, parents’ alcohol consumption, and parents’ depression
Step 2: Adjusted for background confounders + SDQ conduct problems
Step 3: Adjusted for background confounders + SDQ conduct problems + earlier mediator at age 13 (i.e., deviant peers)
Step 4: Adjusted for background confounders + SDQ conduct problems + earlier mediator at age 13 (i.e., deviant peers) + earlier outcome at 13 (i.e., alcohol use)
