Brief summary
The purpose of the study is to determine whether a brief intervention (a short conversation build on the principles of motivational interviewing) is effective in lowering self reported alcohol use in heavy drinkers.
Detailed description
Background and purpose: The Danish national board of Health has awarded 5.6 million DKR to 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 9 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 study will determine whether a brief intervention 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: A) a intervention group receiving a short (about 10 minutes) motivational conversation (build on the principles of motivational interviewing) and two leaflets about alcohol ('Good advice about drinking less' and 'Learn more about alcohol') and a sheet about local alcohol treatment possibilities. The Intervention group is also offered a brief telephone follow up call 4 weeks later. The purpose of this is to maintain the participant's motivation to reduce drinking. B) a control group receiving two leaflets about alcohol ('Good advice about drinking less' and 'Learn more about alcohol') and a sheet about local alcohol treatment possibilities. The study will take place in premises linked to the 'Diet, Smoking, Alcohol and Exercise' nationwide health study. After 6 and 12 months there will be follow-up and the participants will receive a questionnaire with questions about their alcohol consumption.
Interventions
OTHERBrief intervention
The intervention consists of a brief conversation based on the principles of motivational interviewing, including Rollnicks scales to assess the motivation and importance for change. The intervention has duration of about 10 minutes and qualifies as a hybrid between a minimal intervention and a brief intervention. The intervention also consists of two leaflets ('Good advice about drinking less' and 'Learn more about alcohol') on the harmful in having an alcohol above recommended limits, and a sheet about local alcohol treatment possibilities. The Intervention group is also offered a brief telephone follow up call 4 weeks later. The purpose of this is to maintain the participant's motivation to reduce drinking. Employees had been instructed to ask these questions during the intervention: What are you already doing to restrain your drinking? And What can you do more?
