Results: A signiﬁcant decrease in DUDIT-C scores at the 3-month follow-up occurred in both groups. Three out of four statistical models showed a larger decrease in the DUDIT score in the intervention group than in the control group (p = 0.006; p = 0.046; p = 0.001). Two models showed a continued decrease in AUDIT-Cand AUDIT scores also at the 6-month follow-up in the intervention group but not in the control group.No additional differences occurred.
