Introduction: Seizure due to fever is the most prevalent neurological condition in children aged 6 to 60 months. A child's seizure can cause significant distress for parents, particularly the mother. Anxiety control and the well-being of the mother are crucial elements in managing child seizures. 
Methods: In this clinical trial, 70 mothers with children experiencing febrile convulsions were divided into two groups: an experimental group and a control group. The division was done using an available sampling method. The mothers in the experimental group received an intervention based on Orem's self-care model, while the mothers in the control group received the usual care. Mothers' anxiety was assessed one day after the child's hospitalization and again three weeks later using the Spielberger questionnaire. The data was analyzed using descriptive statistics, Chi-square test, Fisher's test, and analysis of covariance in SPSS software version 25.
Results: The study showed that after one day of hospitalization, the anxiety score of mothers in the test group was 101.68, compared to 106.25 in the control group. Three weeks later, the test group's anxiety score decreased to 68.97, while the control group's score was 96.34. Importantly, the decrease in the test group was statistically significant compared to the control group (P = 0.000).
Conclusions: Engaging in self-care activities results in a decrease in maternal anxiety. Hence, it is recommended to employ this approach when caring for children who are hospitalized.
