Scientific title | |
Study objectives | "Smoke-Free Class competition" (SFC) shows a preventive effect on knowledge on smoking, attitudes towards smoking, and smoking behaviour. |
Ethics approval(s) | Approved by state administration department of Saxony-Anhalt (Landesverwaltungsamt Sachsen-Anhalt) on the 31st August 2006 (ref: Reg.-Nr. 504-50/06). |
Health condition(s) or problem(s) studied | Smoking prevention |
Intervention | Since the intervention was planned to take place at the class level, schools were chosen as the unit of randomisation. Experimental schools would provide the SFC, while control schools would provide normal lessons. Intervention - Be Smart Don't Start (the German version of the Smoke-Free Class Competition): Each participating class has to decide if they want to be a Smoke-free Class for a six month period from fall to spring. Classes monitor their (non-)smoking behaviour and report it to the teacher regularly. Classes, in which pupils refrain from smoking for this period of time participate in a prize draw. Control - treatment as usual: Normal lessons. |
