About this trial
The goal of this clinical trial is to learn if telephone-based Acceptance and Commitment Therapy (ACT) works to help young adults with hazardous or harmful alcohol use quit drinking. It will also learn about the psychological effects of ACT on participants.
The main questions it aims to answer are:
1. Does telephone-based ACT increase the number of participants who quit drinking, as confirmed by a urine test? 2. Does telephone-based ACT help participants reduce their alcohol consumption and improve their psychological flexibility?
Researchers will compare telephone-based ACT to a telephone-based social support programme to see if ACT works to help young adults quit drinking.
Participants will:
1. Receive telephone-based ACT or social support once a week for 6 weeks Complete questionnaires about their alcohol use and psychological flexibility. 2. Keep a record of their daily alcohol consumption throughout the study using a standardised diary method. 3. Provide a urine sample at the 6-month follow-up if they report having quit drinking

Trial outcomes
Primary outcomes
1
Biochemically-Validated Abstinence
Participants who self-report quitting drinking in the past 30 days are tested for ethyl glucuronide (a by-product of alcohol metabolism) via urine strips to confirm abstinence biochemically.
Time frame
T4 (6 months after the end of the intervention)Secondary outcomes
1
Self-Reported 30-Day Abstinence
Reduction in alcohol consumption and self-reported 30-day abstinence will be recorded using TLFB. Participants will be asked to report the number of drinks they have consumed within the past 30 days.
Time frame
T0 (baseline), T1 (post-intervention), T2 (1 month after the intervention), T3 (3 months after the intervention), T4 (6 months after the intervention)2
Reduction in Alcohol Consumption
Defined as 50% or more reduction in average alcohol consumption per day compared to baseline, measured using the Timeline Follow-Back (TLFB) questionnaire.
Time frame
T1 (post-intervention), T2 (1 month after the intervention), T3 (3 months after the intervention), T4 (6 months after the intervention)3
Psychological Flexibility Index
Personalised Psychological Flexibility Index(PPFI) will be used to measure psychological flexibility by 19 items rating on a 7-point scale. Higher scores represent greater psychological flexibility. It has been validated among Chinese college students
