Introduction: The purpose of this study was to determine the effectiveness of an educational
program based on the Belief, Attitude, Subjective Norm, and Enabling Factors (BASNEF) Model
on the nutritional behavior among second‑grade, middle school, female students in Isfahan
city. Materials and Methods: This quasi‑experimental study was performed on 72 students.
The samples were randomly divided in two groups (36 in the intervention group and 36 in
the control group). The data collection tools were validated and had reliable questionnaires.
For the intervention group, a 75‑minute educational session was held thrice. The control
group had no education. The BASNEF model constructs guided the development of the
questionnaires and content of the educational sessions. The independent t‑test and paired
t‑test were used to analyze the data. A two-tailed P value lower than 0.05 was considered to
be statistically significant. Result: According to the results, the mean scores of knowledge and
model variables (Belief, Attitude, Subjective Norm, and Enabling Factors) had a significant
difference in the two groups after intervention (P < 0.001). On the basis of the findings, after
educational intervention, 36.1% of the students had unfavorable nutritional behavior. In the
control group, 88.9% of the students had unfavorable nutritional behavior, before and one month
after intervention. Conclusion: The present study showed that nutrition education intervention
based on the BASNEF model could promote the nutritional behavior in girl students.
