Study Overview
=================
Brief Summary
-----------------
The existing alcohol intervention studies are mainly conducted in developed countries, few studies have focused on alcohol consumption among ethnic minority migrant people in developing countries. To address this gap, the investigators aim to evaluate the effects of a brief intervention combined with a small financial incentive on alcohol consumption and health outcomes among the migrated population in Liangshan Prefecture. This study was conducted in Liangshan Prefecture for two reasons: first, Liangshan is a region located in the southwestern of Sichuan province and is populated by Yi minority, and the average income in Liangshan is just about two-thirds of the national average income. Second, a study found that the drinking rate of the Yi minority (47.9%) is higher than that of other regions in China. The aim of this paper is to provide an overview of alcohol consumption among the ethnic populations in China and to test the feasibility and efficacy of small financial incentives with brief advice intervention targeting the reduction of harmful drinking behaviors among poor people.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: Control without intervention<br>No information or cash incentives are provided to the participants in the control group, but it is also necessary to collect the information of the participants in the control group and perform an alcohol test. Therefore, the project team will provide a certain degree of compensation for participants in the control group (participants of the intervention group also will receive this part of compensation). | |
| Active Comparator: Mobile-based information intervention<br>The participants in this group received free three-time counsel and constant multi-media messages about the topic of alcohol consumption for three months. One-to-one counseling services will be provided via a telephone call, which is based on World Health Organization (WHO) recommendations. A total of three counsels are conducted, which are set on the second week, sixth and tenth week after the baseline survey. | Behavioral: Brief Alcohol Intervention<br>* The participants in the treatment group received free three-time counsel and constant multi-media messages about the topic of alcohol consumption for three months. One-to-one counseling services will be provided via a telephone call, which is based on World Health Organization (WHO) recommendations. A total of three counsels are conducted, which are set on the second week, sixth and tenth week after the baseline survey. Brief intervention counselors are from the team of this study and trained by Hongkong University. All counselors are required to attend a full-day workshop before participant recruitment. The contents of the workshop include (1) knowledge of excessive drinking harms and benefits of controlling drinking; (2) overview of AUDIT; (3) alcohol reduction advice; (4) a standard procedure of brief intervention.<br>|
| Active Comparator: Mobile-based information intervention with performance-based incentive<br>The participants in this group were conducted by deducting money. Firstly, a certain amount of vouchers were given to the participants, which was equivalent to the reward for passing seven tests. Then, the voucher would be deducted according to every test result. Finally, the participants will receive cash according to the vouchers. | Behavioral: Brief Alcohol Intervention<br>* The participants in the treatment group received free three-time counsel and constant multi-media messages about the topic of alcohol consumption for three months.
