Arm && Interventions

Group	Intervention	Description
Web-based alcohol programme	interactive online programme to reduce alcohol consumption	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.
Minimum information	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.

Primary Outcome Measures

Name	Time	Method
Change in Weekly Alcohol Intake	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.

Secondary Outcome Measures

Name	Time	Method
Relative Change in Weekly Alcohol Intake	baseline and 6 weeks	(6 weeks minus baseline)/baseline
Category of Change in Weekly Alcohol Intake	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.
Change in the Number of Excessive Drinkers	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
