Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants randomly selected from university enrolment database, sent postal and email invitations to complete baseline survey. Those screening positive for hazardous drinking via computer algorithms within the baseline survey were then automatically allocated to intervention or control group via computerised randomisation. Contacted by letter and email at 1 and 6 months to complete follow ups via web-based interface. In accordance with ethics approval, participants were not informed that the study was a RCT.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Sequence generation conducted by programmer not involved in implementation of the trial on site (therefore not in contact with study participants) by using a randomisation table created by computer software. Sequence applied automatically by computer algorithms during completion of the baseline survey.
Masking / blinding
Blinded (masking used)
