Summary
Brief summary (as posted)
This study aims to evaluate the effectiveness of a community-based Protective Behavioral Strategies (PBS) program in reducing alcohol use, severity of alcohol-related problems, and intention to use alcohol among people with hazardous alcohol use (HAU) in Vietnam. In this randomized controlled trial, 104 men aged 35-44 years, identified as having HAU (Alcohol Use Disorders Identification Test score = 8-15), will be recruited from a rural area in Thai Nguyen province, Vietnam. Participants will be randomly assigned in a 1:1 ratio to either the intervention or control group using stratified blocked randomization. The intervention group will participate in a community-based PBS program, which includes five weekly 90-minute sessions, with Short Message Service (SMS) reminders sent three times weekly after each session to reinforce PBS practices. The control group will receive usual care only. The primary outcome is alcohol use, assessing both the quantity and frequency of consumption, measured at 1 month and 3 months post-intervention. Secondary outcomes include the severity of alcohol-related problems and intention to use alcohol. These will be assessed at baseline and the 3-month follow-up. Two-way repeated measures Multivariate analysis of variance (MANOVA) and regression models will be conducted to evaluate the effects of the intervention on the primary and secondary outcomes.

- description
- Alcohol use is measured by both the amount and frequency of alcohol consumption. The amount of alcohol use is quantified as the total grams of pure alcohol that participants consumed per week in the previous month measuring at baseline, 1 month, and 3 months post-intervention. This is calculated using the formula: Volume (ml) × ABV(%) × 0.79, where ABV is the alcohol by volume percentage and 0.79 is the conversion factor for the density of ethanol. Frequency of alcohol use is defined as the number of days per week in the previous month that participants consume alcohol measuring at baseline, 1 month, and 3 months post-intervention. These variables are measured using the Alcohol Timeline Follow back (TLFB).
