Multi-stage cluster sampling was used in this study. One out of six districts of Isfahan’s education department and then 12 schools out of 24 state high schools were selected randomly using the drawing method. Among them, six schools were randomly considered to select individuals in the intervention group, and six schools were considered for selecting control group individuals using a table of random numbers. Ten teachers were selected voluntarily from each school via convenience sampling to participate in the research.According to the equation of = Three and six months after the intervention, the post-test was administered in both the intervention and control groups to examine the effects of education on primary and secondary outcomes. The primary outcomes of the current research included the constructs of PEN-3 (perceptions and enabler factors), and the secondary outcome was breast cancer screening behavior in women. According to experts’ opinions, due to the time required to make an appointment for mammography and clinical examinations, 3 months of follow-up was not enough to perform breast cancer screening behaviors, so the behaviors were assessed only before and 6 months after training.Based on the nature of the intervention in the present study, the instructor was not blinded to group assignment, but participants and the statistical investigator were blinded to group assignment.
