(2) For the alcohol intervention group, participants will also receive a brief smoking cessation intervention with the models as the ST group. After that they will receive a brief advice on alcohol use based on the FRAMES model. Then the RA will invite participants to complete the Alcohol Use Disorders Identification Test(AUDIT).

Then the RA will invite participants to complete the Alcohol Use Disorders Identification Test and provide personalized feedback. There will be a one to one, 20-30 minutes semi-structured interviews with 30 participants. Participants with high(N=15) and low (N=15) adherence will be purposively selected. A booster intervention will be given over the phone at 1-week, 1month, 3-month, and 6 month follow-up. |
