Aims:
To examine the use of the Internet in a survey of drinking among students, and the effectiveness of incentives to encourage participation.
Methods:
In a survey of drinking in university students, a random sample of 160 students were randomly assigned to one of four token incentive conditions. All received posted invitations, and reminders by e-mail and telephone.
Results:
Overall response was 85% and did not differ significantly by incentive condition.
Conclusion:
Internet surveys are effective in obtaining alcohol use information from students. Minimal incentives may suffice if coupled with intensive follow-up.
