简要总结
The purpose of the study is to determine whether a web-based ultra-brief intervention, consisting of personalized normative feedback or standardized self-help material, is effective in lowering self reported alcohol use in heavy drinkers.
详细描述
Background and purpose:
The Danish national board of Health has awarded funds for two studies that will test methods that can be used for effective and early detection of heavy drinkers. The study will be carried out in 12 Danish municipalities in 2008. The study is part of the 'Diet, Smoking, Alcohol and Exercise' nationwide health study of the Danish population. It takes place in 13 municipalities in 2007 and 2008.
The purpose of the study is to determine whether a web-based ultra-brief intervention, consisting of personalized normative feedback or standardized self-help material, is effective in lowering self reported alcohol use in heavy drinkers.
Design:
The experiment is designed as a randomized controlled trial, where heavy drinkers will be allocated to either:

研究组 & 干预措施
1
Personalized normative feedback (PFI). The PFI was a single-session intervention; it was displayed in a single screenshot and addressed the participant by name. It consisted of a summary of the participant's weekly consumption, a comparison with maximum drinking limits and a graphical comparison of the participant's consumption to the average level in the municipality (gender-specific), followed by information about health and social risks of heavy drinking as well as links for further self-help material and a local alcohol treatment facility.
干预措施: Personalised normative feedback (PNF) (Other)
2
Self-help material (SHM). The SHM was a single-session intervention and was displayed in a single screenshot. It consisted of information about maximum drinking limits, followed by information about health and social risks of heavy drinking as well as links for further standardized self-help material and a local alcohol treatment facility.
干预措施: Self-help material (Other)
3
Control
干预措施: Control (Other)
