Validation of the Georgian version of a Stigma Scale of Epilepsy

Introduction: Stigma Scale of Epilepsy (SSE), initially developed in Brazil, is accepted worldwide as a sensitive tool for assessing epilepsy-related stigma. We adapted and validated a Georgian version of SSE.Materials and methods: The SSE originated in Brazil and was translated into Georgian by three independent experts through forward and backward translation. The final version was generated for validation after handling gross or conceptual inconsistencies between the source and the new format. We used Cronbach's alpha to assess the internal consistency of the Georgian version of SSE. To explore the construct of SSE subscales in the Georgian version, we used principal components and factor analysis. Varimax rotation was applied. The Kaiser-Meyer-Olkin Measure and Bartlett's test of sphericity were employed to assess the sampling adequacy. A probability <0.05 was considered statistically significant.Results: 87 adults, 32 (37 %) with epilepsy and 55 (63 %) without epilepsy were enrolled. The overall mean score of SSE was 19.5 (SD 10.1; min. 2, max. 53), and the differences between people with [20.7 (SD 8.9; min. 2, max. 53)] and without epilepsy [17.5 (SD 10.4; min. 3, max. 42)] were not statistically significant. Cronbach's alpha for the overall sample was 0.854; for the epilepsy cohort it was 0.876, and for individuals without epilepsy 0.823, indicating good SSE internal consistency. Kaiser-Meyer-Olkin Measure was 0.705 and Bartlett's test of sphericity was 926.2 (df 276; p < 0.001), suggesting acceptable sample adequacy.Discussion: The Georgian version of the SSE is a valid and reliable measurement tool for assessing epilepsy-related stigma determinants among the country's population.
