Results:
The results showed that there were differences in attitudes (p=0,001), subjective norms (p=0,005) and intentions (p=0,046) between before and after the intervention with STAD but there were no differences in PBC (p=0,059).

Conclusion(s):
student team achievement division may use to intervene students to have a positive attitude, good subjective norms, and strong intentions toward smoking prevention behavior
