|- Scientific Title||Testing “Hou vol! Geen alcohol”, a prevention program for parents and elementary schoolchildren targeted at delaying the age of alcohol onset of Dutch youth.|
|- ACRONYM||Hou vol! Geen alcohol / In control! No alcohol|
|- hypothesis||Two hypotheses will be tested. First, we expect parents in the experimental group, who drink as well as those who abstain from alcohol, to use more alcohol-specific socialization strategies than parents in the control group. Second, we expect that children involved in the "Hou vol! Geen alcohol" intervention will be less likely to start drinking than children in the control group.|

|- Interventions||The objective of the present study is to test an intervention program focusing on anti-alcohol socialization skills for parents of primary schoolchildren: "Hou vol! Geen alcohol". "Hou vol! Geen alcohol" is a home-based program and consists of a series of five activity guides for parents and children to complete together. These guides will be mailed to their homes every month.
For the control group an alternative program will be used based on facts. These factsheets provide knowledge about youth drinking and focuses parents attention on macro level variables relevant to youth drinking but not targeted by treatment versions of the program.
