How is the study designed?

Design Details

  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Web-based alcohol programme

Participants could log on to their account and access the programme whenever they wanted to.

They received automated email reminders inviting them to use follow-up tools, especially the diary in order to register their alcohol intake on the previous week:

  • 4 weeks after starting the programme, so that they would take advantage of the monitoring stage in case they had not spontaneously done so.
  • 2 weeks later for 6-week follow-up.
Behavioral: interactive online programme to reduce alcohol consumption

The programme includes several steps:

  • personalized feedback on alcohol consumption and related risks
  • reviewing motivations and fears regarding drinking reduction
  • analyse of drinking habits
  • reduction goal setting
  • follow-up tools (alcohol diary, craving scales, well-being scales)
  • a final screen allowing participants to monitor their progress through graphs and automatically adapted comments.
Placebo Comparator: Minimum information
Participants could log on to their account and access the programme whenever they wanted to. At 6 week follow-up they received an automated email reminder inviting them to use the diary in order to register their alcohol intake on the previous week.
Behavioral: Minimum information

This intervention includes:

  • information about hazardous drinking
  • an alcohol diary

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Weekly Alcohol Intake
Time Frame: baseline and 6 weeks
The unit of "standard drink" is a drink containing 10g of pure alcohol. Participants had to report their weekly alcohol intake in a diary, in which they could choose among 21 glasses of various capacities and containing various alcoholic drinks. Each of those glasses was then converted into standard drinks.
baseline and 6 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Relative Change in Weekly Alcohol Intake
Time Frame: baseline and 6 weeks
(6 weeks minus baseline)/baseline
baseline and 6 weeks
Category of Change in Weekly Alcohol Intake
Time Frame: baseline and 6 weeks

Category of change in weekly alcohol intake (WAI) is a 3-level categorical variable whose values are:

  • clinically significant reduction in WAI, defined as a decrease of 10% or over;
  • clinically significant increase in WAI, defined as an increase of 10% or over if WAI at baseline is positive, or any increase if WAI at baseline is 0);
  • and no clinically significant change, which includes all other cases.
baseline and 6 weeks
Change in the Number of Excessive Drinkers
Time Frame: baseline and 6 weeks
The number of excessive drinkers is the number of participants whose weekly alcohol intake exceeds guidelines, i.e. 21 or 14 standard drinks (male/female) per week
baseline and 6 weeks
