Objective: To control the effects of tobacco interventions on smoking cessation among college students with different social support levels from the perspective of the health belief model, and to provide reference for effective
intervention of smoking among college students with different social support levels. Methods: According to the score of the Nicotine Dependence Test Scale (FTND) and
the Social Support Rating Scale, 90 male college students with smoking behavior were selected as the respondents. The 2×3 inter-tester experimental design was adopted, in
which the independent variable was social support. Levels (high social support and low social support) and different forms of smoking interventions (video intervention
group, picture intervention group and control group), the dependent variable is the number of changes in the degree of nicotine dependence of the subject. Results:
There were no significant differences in the degree of nicotine dependence between the image and video intervention groups, but they were significantly lower than the control group (p<0.05). There was a significant difference in the amount of nicotine dependence between the superior social support level group and the low social
support level group (p<0.05); there was just an interaction between social support and smoking interventions on the effect of smoking cessation (p<0.05). Conclusion: In the perspective of the health belief model, the intervention of smoking students through video and picture materials can effectively improve the nicotine dependence of smoking college students. The effect of the picture material is slightly better than the video group but not statistically significant. Intervention materials have high social
support level. The intervention effect of the participants was preferable to that of the subjects with low social support.
