Adolygiad Sylfaenol NICE
Mae'r awduron yn datgan:
"Smokefree Class Competitions (SFCC) are a school-based incentive intervention for preventing the uptake of smoking, usually among children between 11 and 14 years old. SFCC gives responsibility for preventing smoking uptake (and stopping smoking for the duration of the competition, for those who already smoke) to the class of students. The intended effect is to denormalise smoking and create a smokefree class through the use of peer expectations of each other. There has previously been mixed evidence of effectiveness, and some concerns about whether the intervention might have adverse effects when implemented to do with bullying and peer pressure."
