BREAST CANCER
The strength of the present study is that the design of the educational intervention was based on the PEN-3 model as well as on the follow-up of the behavior of teachers 6 months after the educational intervention.The limitations of the present study were as follows: due to time and performance constraints, we could not consider nurturers for intervention, which had a significant impact on screening behavior as interventions to change the behavior. Furthermore, the first dimension of the PEN-3 model, indicating the impact of neighborhood and extended family on behavior implementation or change, was not utilized in the present study. Hence, it is suggested to use all three dimensions of the PEN-3 model to perform or change breast cancer screening behavior in future studies. This study was conducted among teachers from a specific area in Iran, and the results may not be generalizable to other populations, so conducting a study in another population is recommended. Another limitation of this study was that it was designed in a quasi-experimental way. If it were a clinical trial study, it would be possible to draw better and more accurate conclusions by following the principles of CONSORT.
