Secondary outcomes
SECONDARY
The secondary outcomes were determinants expected to impact students’ smoking behaviors as prespecified in the trial registration and study protocol [Among daily smokers, cigarettes smoked during school hours and nicotine dependence were measured at follow-up. Among regular smokers, outcomes such as intention to quit smoking, self-efficacy, smoking behavior at school, and knowledge about smoking cessation services were measured at follow-up. Among non-smokers, intention to initiate smoking was examined at follow-up. Finally, among all students, outcomes at follow-up included mood effects of smoking, social benefit effects of smoking, school well-being, and visibility and perception of smoking at school and among classmates.
