Introduction: Diabetes mellitus is the most common metabolic disease and can lead to serious
complications such as blindness, limb amputation, renal failure, and cardiovascular disease.
Gestational diabetes is diagnosed as impaired glucose tolerance for the first time during pregnancy.
On the other hand, there is a relationship between diabetes and self-efficacy. One of the important
patterns that builds on the ability of individuals and their needs for self-care is our self-care model.
Therefore, the aim of this study was to determine the effect of self-care education program based
on self-care pattern of Orem on self-efficacy in women with gestational diabetes mellitus.
Materials and Method: This was a quasi-experimental study of pre and post type, which was
performed on 42 patients with gestational diabetes mellitus. The data collection tools were
demographic information questionnaire and diabetes self-efficacy scale (CIDS), which were
completed and compared before and after intervention. Data were analyzed by SPSS software
Results: The mean of self-efficacy score was 52.66 ± 5.27 before the intervention, but after the
intervention, the mean score of this score was 77.21 ± 9.13, which can be said to be samples after
participation in Educational sessions have a high level of self-efficacy. Comparison of mean score
of self-efficacy before and after intervention was statistically significant (P = 0.01).
Conclusion: The results showed that using self-care education using Orem self-care model for
GDM patients increases the average performance of all aspects of self-efficacy in these
individuals. According to this, if self-care program implementation can be continued according to
patient's self-care needs and can be tailored to the level of their perception, they can achieve
positive results in the health of these people and help them to improve their health.
