[Psychometric properties of the Stigma Scale of Epilepsy]

To assess the psychometric properties of the Stigma Scale of Epilepsy, a short simple to complete questionnaire to quickly and reliably determine the presence and the level of perceived stigma in a particular patient, as well as to assess the prevalence, socio-demographic, clinical and socio-psychological factors associated with this phenomenon.

The study included 398 patients with epilepsy. Exploratory (EFA) and confirmatory factor analysis (CFA) were used to assess the psychometric characteristics of the scale.

The EFA showed a two-factor scale structure explaining 57.25% of the variance. Values of GFI 0.948, CFI 0.927 and RMSEA 0.057 after the data correction show a good conformity of the model to the empirical data. Cronbach's alpha coefficient was 0.862 for the scale, 0.815 for factor 1, 0.809 for factor 2, which indicates a high consistency of both the entire scale and its subscales. The Russian-language variant of the Stigma Scale of Epilepsy is a short, economical to use tool with good psychometric properties for assessing perceived stigma in patients with epilepsy.
