A random multiple-stage sampling was used and divided into 48 subjects as case group and 49 subjects as control group. A questionnaire based on HBM was prepared whose validity and reliability was approved and given to samples. Based on the data achieved from the pre-test, an educational program was designed and applied on the case group. Three months after intervention, a second evaluation was conducted by the same questionnaire. Collected data were analyzed by using t-test،paired t-test and chi-square.P value less than 0.05 was considered statistically significant.
Results: Results showed that before training intervention, the mean score of knowledge, preventive behaviors, and all constructs of HBM were more than mediate. After training intervention, significant difference was observed in all variables of both groups (p<0.05). Also, rate of case group's using coitus interrupt was decreased from 40% to 9.65%.
Conclusion: Health education program designed based on Health Belief Model has had a positive effect on the preventive behaviors of unwanted pregnancy and may have an effective role on decreasing unwanted pregnancy incidence rate in women’s.
