In addition to seizure care, it has been well-established that a holistic approach to the treatment of children with epilepsy that addresses the social, behavioral, and psychological dimensions also benefits their quality of life (QoL). The aim of this study was to investigate the patient and parental perceived stigma, seizure self-efficacy of children with epilepsy, and the relationship with quality of life in terms of sociodemographic and epilepsy-related factors. The study group consisted of children, aged between 8 and 18years and with a diagnosis of epilepsy of at least six months duration and their parents. Pediatric Quality of Life Inventory (PedsQL), Child-Parent Stigma Scales, and the Seizure Self-Efficacy Scale for Children (SSES-C) were used for evaluation. One hundred and forty-four children (mean age 12.6 ± 2.9years) took part, of whom 48.6% were female. The mean Child Stigma Scale score was 1.77 ± 0.82, Parent Stigma Scale score 2.41 ± 0.75, SSES-C score was 3.37 ± 0.98, and PedsQL score was 72.8 ± 18.6 for children self-reports (CsR) and 73.2 ± 18.8 for parent proxy-reports. The intraclass correlation coefficient for parent-child PedsQL indicated a good level of agreement. There was a significant negative correlation between the Child Stigma Scale and the PedsQL-CsR scores. A significant positive correlation was identified between the SSES-C scores and the PedsQL-CsR scores. Perceptions of stigma in children with epilepsy and their parents were high in this study population. Of note, the elevated stigma perception reported by the patients had a detrimental impact on seizure self-efficacy. This relationship may affect the children's QoL and further complicates epilepsy management in this patient group.
