'I bet I can do it!' - Reach and effectiveness of a television show about smoking cessation among low, moderate, and high educated smokers.

The reach of 'I bet I can do it!' and the effect on quit attempts was larger among moderate educated smokers. The entertainment-education strategy for smoking cessation television programs should be further refined. This can possible lead to a program that has positive effects on the quit intention, self efficacy, quit attempts and the quit success of low and moderate educated smokers.
