Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Average number of risky drinking days per month | standard drinks | one month | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Average weekly alcohol consumption | standard drinks | one month | 
| craving level | Pennsylvania Alcohol Craving Scale (PACS) is a single factor, multidimensional scale, Chinese version of the reliability and validity has been verified. The five items assessed frequency, intensity, duration, ability to cope with drinking and average craving on a scale of 0 to 6 points, with higher scores indicating higher craving levels. | two weeks | 
| Alcohol, Smoking, and Substance Use Involvement Screening Test (ASSIST) score | ASSIST(alcohol) was developed by the World Health Organization, based on existing screening tools, to assess risk levels for psychoactive substance use, the Chinese version has been validated for reliability and validity. There are 7 entries in the ASSIST alcohol section, and question 1 does not count towards the total score; Questions 2-5 0= never, 2= once or twice, 3= once a month, 4= once a week, 6= almost every day; Questions 6- 7,0 = never, 3= Yes but three months ago, 6= Yes in the past three months. Scores for questions 2-7 were added together to obtain an overall score for alcohol use, with 0-10 being low risk, 11-26 moderate risk, and 27+ high risk, with tertiary risk corresponding to no treatment, brief intervention, and referral to a specialist for evaluation and treatment. | three months | 
| willingness and confidence to abstain | The 4-item Assessment Scale of awareness, readiness and confidence in the importance of behavioral change in psychoactive substance use in the Intervention manual is scored from 0 to 10. The higher the score, the higher the degree. | one month | 
| stages of motivation for abstinence change | Developed by Dong Wang (2013) based on Prochaska and DiClemente's cross-theoretical model of behavioral change, It includes three dimensions: the precontemplation stage (P), the contemplation stage (C) and the action stage (A). There are 4 questions in each dimension. 1-5 points are scored. 1= strongly disagree, 2= disagree, 3= not sure, 4= agree, 5= strongly agree. | one month | 
| Depression, PHQ-9 | Kroenke and Spitzer (2002) revised depression screening Scale Patient Health Questionnaire, PHQ-9 based on DSM-IV diagnostic criteria, and the reliability and validity of the Chinese version have been verified (Xiaoyan Sun, Yixue Li, Canqing Yu, Liming Li, 2017). There are 9 entries, 0 to 3 on a four-point scale, 0= never at all, 1= days, 2= less than half of days, 3= almost every day. Total score 0-4 for clinically insignificant depression, 5-9 for mild depression, 10-14 for moderate depression, and 15+ for major depression. | one month | 
| Anxiety, GAD-7 | Generalized Anxiety Disorder, GAD-7's reliability and validity of the Chinese version of the module used to screen for generalized anxiety disorder in the Patient Health Questionnaire (PHQ) developed by Spitzer et al. (2006) (Wang Yu, Chen Ran, Zhang LAN, 2018). There are 7 entries, 0 to 3 on a four-point scale, 0= never at all, 1= days, 2= less than half of days, 3= almost every day. Total score 0-4 for clinically insignificant anxiety, 5-9 for mild anxiety, 10-14 for moderate anxiety, and 15+ for severe anxiety. | one month | 
| Sleep status, ISI | Insomnia Severity Index, ISI was compiled by Morin et al. (2001), the Chinese version of ISI-C has been tested to have good reliability and validity, and is suitable for the evaluation of insomnia in clinical patients in China (Bai Chunjie et al., 2018), with a total of 7 items, scoring 0-4 and 5 points. Total scores were 0-7 for nonclinically significant insomnia, 8-14 for subclinical insomnia, 15-21 for moderate clinical insomnia, and 22-28 for severe clinical insomnia. | one month | 
| Stress perception, PSS-10 | Perceived Stress Scale, PSS-10 is the most widely used self-assessment tool for stress feeling has high reliability and validity for the version of 10 items, 0-4 points score, 0= never, 1= rarely, 2= sometimes, 3= more, 4= very common, questions 4, 5, 7, 8 score in reverse, the higher the score indicates the higher the level of perceived stress. | one month |
