Objective@#This study conducted a
tobacco control intervention practice on vocational
school students based on
social cognitive theory, for exploring the practical and feasible
tobacco control strategies among
students, so as to reduce
adolescents’
smoking behaviors.@*
Methods@#Cluster random sampling
method was used to select
students in four vocational
schools in Shanghai, which were randomly divided into the intervention group (2
schools 1 003
students) and the
control group (2
schools 1 096
students). The intervention was conducted on the intervention group based on the
social cognitive theory and lasted for 6 months. The
control group was blank. Descriptive and analytical statistical
methods were used to evaluate the effect of intervention.@*Results@#After the intervention, in the intervention group, the current
smoking rate (2.77%) and the
smoking intention in the next 1 year (8.50%) both decreased, the scores of the
cognition of the harm of
smoking as well as second
hand smoking and the
attitudes towards tobacco all increased(39.04%, 32.93%), the
self-
efficacy of refusing
smoking increased (88.93%), the social
pressure decreased(12.40%), the exposure rate of
secondhand smoke in
family decreased(35.45%), and the exposure to
tobacco control message on media increased (36.68%). The difference was statistical significant compared to the
control group (χ2=8.67,19.32,17.87,8.32,13.51,14.71,17.36,20.09,P<0.01).@*Conclusion@#The
tobacco control model based on
social cognitive theory could effectively improve
adolescents’
self-
efficacy, increase their tobacco-related
knowledge, and significantly reduce their
future smoking intention and
behavior.
