Study type
Interventional
Description of intervention(s) / exposure
B: Screening (The screening involves patients to complete the 10-item Alcohol Use Disorders Identification Test (AUDIT) at a computer in the waiting area which is connected to the Internet. They also answered questions about the largest amount they consumed in a single episode in the last 4 weeks, the duration of the episode, their age, gender, and ethnicity. It takes 3 minutes.), information leaflet (An educational leaflet providing information on the effects of alcohol and recommended upper limits for low-risk consumption) plus assessment of alcohol use, perceptions of peer drinking norms, and problems 4 weeks later. The assessment involves a 14-day retrospective account of drinks per day, the Alcohol Problems Scale - 14 items, the Academic Role Expectations and Alcohol Scale - 5 items, estimates of others' drinking (7 items) and their height and weight. Median completion time is 11 minutes.
C: Web-based motivational intervention (single-dose); including comparison of patient's drinking with age/gender norms and recommended upper limits. This intervention takes 11 minutes to answer the questions (see above) plus the time required to read the feedback, which we estimate to be 3-5 minutes. Overall, total time is approximately 15 minutes.
D: Web-based motivational intervention (multi-dose); as in C, provided at the commencement of the trial, at 6 months and at 12 months. This intervention takes 15 minutes at baseline and a further 10 minutes four weeks later for assessment and feedback.

Behaviour
Comparator / control treatment
A: Screening and information leaflet (control). An educational leaflet providing information on the effects of alcohol and recommended upper limits for low-risk consumption. The screening involves patients to complete the 10-item Alcohol Use Disorders Identification Test (AUDIT) at a computer in the waiting area which is connected to the Internet. They also answered questions about the largest amount they consumed in a single episode in the last 4 weeks, the duration of the episode, their age, gender, and ethnicity. It takes 3 minutes.

Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Research staff involved in the trial were not informed of participants’ group allocation during intervention or follow-up. The generation of the sequence and loading of it into the server database were conducted by off-site staff who were not involved in the implementation of the trial on site, who never came into contact with study participants. Participants were informed that they were participating in a series of surveys about their drinking. Thier perceptions were checked in a pilot study, and found to be consistent with the aim to conceal group allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The random sequence was generated in Microsoft Excel using the rand function, and this was loaded into the server which administered the intervention.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
Subjects were blind. Note: there were no assessors or therapists as such: all done by computer. The intervention, assessment, and analysis may therefore be said to have been conducted blindly.

Summary
Brief summary
There is compelling evidence for the efficacy of screening and brief intervention (SBI) for hazardous drinking, yet it is not widely available in primary healthcare. Electronic (computer/web-based) intervention offers the prospect of ease, simplicity, and economy of access.
The objective was to examine whether electronic SBI (single- and multi-intervention) reduces hazardous drinking and related problems compared with an information leaflet alone (control condition).
Design and Setting: Randomized controlled trial at a university health service (enrolment 8/2003), with follow-up measures taken at 6 and 12 months.
