Validity and reliability of Turkish version of the scales of perceived stigma for children with epilepsy and their parents

Abstract

PurposeThis study aims to establish a Turkish version of the scales of perceived stigma amongst children with epilepsy and their parents by adopting the scales developed by Austin et al. This study also aims to analyse the scales' validity and reliability in evaluating stigma perceptions amongst the aforementioned population. MethodsThe population of this methodological study consisted of parents and 85 epileptic children between 9 and 16 years old. This population visited the paediatric neurology clinic of a hospital in Erzurum Province, Turkey, between April 2015 and January 2016. The scales of perceived stigma amongst children with epilepsy and their parents, as well as its Turkish version, were used as measuring tools. Experts were also consulted for their opinions. Meanwhile, Bartlett's test, Kaiser–Meyer–Olkin (KMO) index, exploratory factor analysis, principal component analysis, varimax rotation and scree plot test were used to determine the validity of the study. Moreover, the coefficients of Cronbach's α and Pearson's product-moment correlation were used to identify internal consistency, homogeneity and thus reliability. ResultsEvaluations and analyses indicated that the Turkish version of the child and parent scales can be used with a single dimension. The mean scores of such scales were 24.02 ± 8.47 and 15.68 ± 4.04, respectively. All item-total score correlations of the child and parent scales were found to be significant (P < 0.05). The KMO coefficient of the child scale was 0.94, whereas the chi-square value of Bartlett's test of sphericity was significant at 209.311 (P < 0.05). Moreover, the KMO coefficient of the parent scale was found to be 0.80, whereas the chi-square value of Bartlett's test of sphericity was found to be significant at 209.311 (P < 0.05). The Cronbach's α coefficients were 0.95 and 0.87 for the child and parent scales, respectively. ConclusionThe Turkish version of the child and parent scales of perceived stigma is valid and reliable in measuring the perception of stigma amongst children with epilepsy and their parents.
