Evaluation of "The Healty School and Drugs" (= "De Gezonde School en Genotmiddelen") for elementary schools.

Te aim of the study is: To assess the effectiveness of the universal program “The Healthy School and Drugs” (= “De Gezonde School en Genotmiddelen”) for elementary schools by conducting a clustered pilot randomized controlled trial including Dutch elementary schools. The outcome will not be direct effects on substance use behavior, but effects on the determinants underlying this behavior: Attitude, social influence, self-efficacy and the intention to use in the future.

Children in the intervention conditions will be more likely to have negative attitudes and norms towards smoking and alcohol than children in the control condition.

Plan:

T1: November 2011;

T2: April 2012.

There are two intervention conditions and a control condition.The first intervention includes the use of the two textbooks “Smoking" and " Alcohol". At the end of the intervention, an information evening will be organized by the local Municipal Health Service to involve the parents. For the teachers a manual is available. In the second intervention the students will use the textbook “Alcohol & smoking, another story". Also an evening for parents will be organized. At this evening the children will present what they have learned during the intervention and they will show what they have designed as part of different assignments described in the manuals. Also for this intervention a manual is available for the teachers. The control condition is characterized by business as usual and does not
receive an intervention.
