The data were collected using a demographic information form and the standardized inventory for QOL in patients with epilepsy (QOLIE-31-P). The inventory contains 31 items measuring 7 dimensions of QOL and one general item examining the importance of the dimensions related to the disease. The dimensions of the inventory are as follows: seizure worry, mental health, energy/fatigue, cognitive functioning, medication effects, social functioning, and the overall QOL. The score of each scale is measured according to the scoring guide of the inventory. The scores range from 0–100, with higher scores indicating higher QOL. The reliability and validity of this scale have already been evaluated in Iran, and the reliability of most of the dimensions is confirmed. To respect ethics, a written permit was adopted from the translator of the inventory. The training materials consisted of two parts. The first part that was provided in the first session was about the medical aspects of epilepsy including the definition of epilepsy, description of seizures, types of seizures, observation and classification of its causes, and diagnosis of epilepsy. Moreover, the case group received an epilepsy instructional booklet containing the content of the training program. The second part that was provided within three sessions for promoting self-management was about medication management, information management, safety management, lifestyle management, and seizure management. The materials were presented face-to-face using PowerPoint presentations. These materials were already prepared by Aliasgharpour et al., its face validity on 15 patients with epilepsy had been confirmed, and it had been examined and revised in terms of readability, fluency, and understandability. Their study showed that the training had significant effects on the self-management of patients with epilepsy. The patients in the case group received both the routine care and the training intervention for improvement of self-management. To do so, they were divided into 5 groups (5–6 patients in each group) and received the training intervention within four 2-hour sessions in one month. We phoned the entire group before every session to encourage them to attend. The participants completed the inventory for QOL (QOLIE-31-P) before and one month after the intervention. The control group received only the routine clinical care and was contacted only through two short phone calls during the month. The case group received the intervention. All of the participants in the two groups completed the study. The groups filled out the posttest when they referred to the center for their treatment
