Development of the perceived stigma scale and the concealment of epilepsy scale for the Turkish population.

The aim of this study was to develop two culture-specific scales to measure the level of felt stigma, and level of concealment of Turkish adult people with epilepsy (PWE). For this purpose, a 10-item felt-stigma scale and a 17-item disclosure of epilepsy scale were developed and then applied to 200 adult PWE. After item and factor analyses of the stigma scale, the 10 items with a one-factor solution explained 45.6% of the variance with a 0.86 internal consistency value. Higher scores represent higher felt stigma. The concealment of epilepsy scale has 17 items loaded on one factor, which explained 45.1% of the variance. Cronbach's alpha coefficient was found to be 0.92. The higher the score, the higher the concealment of illness by the participant. For convergent validity, the relationship between stigma and disclosure scales was examined, and a positive significant relation (r=0.64, p<0.000) was found.
