[A key role for physicians in identifying, discussing and referring problematic alcohol use].

Introduction: Alcohol consumption increases the risk of approximately 200 health conditions. Nature, severity, and prevalence of alcohol-related issues in the Netherlands warrant more structured attention in medical consultations. Over 20 GP-guidelines recommend addressing alcohol consumption and providing advice.

Consumption of alcohol-free and alcoholic beverages among Dutch university students: Substitution or addition?

Introduction: Alcohol-free drinks are suggested as healthy alternatives for alcohol consumption. To achieve benefits, alcohol-free beverages must be consumed as a substitute for alcoholic beverages, not in addition. This study examined in a student sample (i) the frequency/quantity of alcohol(-free) consumption; (ii) the relationship between alcohol-free and alcohol consumption; (iii) alcohol-free drinks as substitution or in addition to alcoholic drinks; and (iv) possible gender differences.

The effect of the 'What Do You Drink' web-based brief alcohol intervention on self-efficacy to better understand changes in alcohol use over time: randomized controlled trial using ecological momentary assessment.

Background: To examine whether (1) the 'What Do You Drink' (WDYD) intervention resulted in drinking refusal self-efficacy (DRSE) changes directly after the intervention, and if so, whether these changes sustained at six-months follow-up and (2) DRSE was related to alcohol use over time, and if so, whether the strength of these relationships differed across conditions. Insight herein can help explain the sustained preventive effects of the WDYD intervention on alcohol use, as reported previously.

Methods: Alcohol use and DRSE data were collected from 907 participants (60.

Using ecological momentary assessment in testing the effectiveness of an alcohol intervention: a two-arm parallel group randomized controlled trial.

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.

The effectiveness of a web-based brief alcohol intervention in reducing heavy drinking among adolescents aged 15-20 years with a low educational background: a two-arm parallel group cluster randomized controlled trial.

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.

The development of a web-based brief alcohol intervention in reducing heavy drinking among college students: an Intervention Mapping approach.

In the Netherlands, young adults' drinking practices have become an issue of public concern since their drinking levels are high. Heavy drinking can place young adults at an increased risk for developing short- and long-term health-related problems. Current national alcohol prevention programmes focus mainly on adolescents and their parents and paying less systematic attention to young adults.

The effectiveness of the 'what do you drink' web-based brief alcohol intervention in reducing heavy drinking among students: a two-arm parallel group randomized controlled trial.

Aims: To evaluate the effectiveness of a web-based brief alcohol intervention 'What Do You Drink' (WDYD) among heavy drinking students at 1- and 6-month post-intervention. Additionally, it was investigated whether certain subgroups would benefit more than others from the WDYD intervention.

Methods: A two-arm parallel group randomized controlled trial was conducted online in the Netherlands in 2010-2011.

The effectiveness of a web-based brief alcohol intervention in reducing heavy drinking among adolescents aged 15 to 20 years with a low educational background: study protocol for a randomized controlled trial.

Background: The serious negative health consequences of heavy drinking among adolescents is cause for concern, especially among adolescents aged 15 to 20 years with a low educational background. In the Netherlands, there is a lack of alcohol prevention programs directed to the drinking patterns of this specific target group. The study described in this protocol will test the effectiveness of a web-based brief alcohol intervention that aims to reduce alcohol use among heavy drinking adolescents aged 15 to 20 years with a low educational background.

Targeting young drinkers online: the effectiveness of a web-based brief alcohol intervention in reducing heavy drinking among college students: study protocol of a two-arm parallel group randomized controlled trial.

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.
