Background: Alcohol consumption of college students has a fluctuating nature, which might impact the measurement of intervention effects. By using 25 follow-up time-points, this study tested whether intervention effects are robust or might vary over time.
Methods: Data were used from a two-arm parallel group randomized controlled trial applying ecological momentary assessment (EMA) with 30 data time-points in total.
Background: To evaluate the slightly modified version of the web-based brief alcohol intervention "What Do You Drink" (WDYD) among heavy drinking adolescents and young adults aged 15-20 years with a low educational background at one and six months follow-up.
Methods: A two-arm parallel group cluster randomized controlled trial was conducted online in the Netherlands in 2011-2012. Participants included in the trial were recruited from preparatory and secondary vocational education institutions and had to be between 15 and 20 years of age and report heavy drinking in the past six months.
Article Synopsis
- Young adults in the Netherlands are drinking heavily, raising public health concerns due to potential short- and long-term health issues.
- Current alcohol prevention efforts focus more on adolescents and their parents, neglecting the young adult demographic.
- The study introduces a web-based intervention called What Do You Drink (WDYD), designed using the Intervention Mapping (IM) protocol, aiming to help young adults reduce their alcohol consumption to meet Dutch low-risk drinking guidelines through motivational interviewing and tailored strategies.
Article Synopsis
- The study assessed the effectiveness of the web-based alcohol intervention 'What Do You Drink' (WDYD) among heavy drinking students at 1- and 6-month follow-ups.
- A randomized controlled trial included 913 participants aged 18-24 who were heavy drinkers and motivated to change; they were split into an intervention group (WDYD) and a control group.
- Results showed no overall effectiveness in reducing alcohol consumption, but certain subgroups (e.g., those ready to change or with severe drinking issues) benefited short-term from the intervention.
Article Synopsis
- The study focuses on addressing heavy alcohol consumption among adolescents aged 15 to 20 with low educational backgrounds in the Netherlands, as current prevention programs are lacking.
- A web-based intervention, "What Do You Drink" (WDYD), will be tested on 750 participants through a randomized controlled trial, comparing its effectiveness against a control group with no intervention.
- The primary outcomes will measure changes in drinking within safe limits, weekly consumption, and binge drinking frequency, alongside secondary outcomes related to alcohol-related attitudes and self-efficacy over specified time points.
Background: The prevalence of heavy drinking among college students and its associated health related consequences highlights an urgent need for alcohol prevention programs targeting 18 to 24 year olds. Nevertheless, current alcohol prevention programs in the Netherlands pay surprisingly little attention to the drinking patterns of this specific age group. The study described in this protocol will test the effectiveness of a web-based brief alcohol intervention that is aimed at reducing alcohol use among heavy drinking college students aged 18 to 24 years old.
