Psychometric evaluation of the Turkish adaptation of the Epworth sleepiness scale for children and adolescents

The aim of our study was to investigate the psychometric properties of the Turkish adaptation of the Epworth Sleepiness Scale for children and adolescents (ESS-CHAD). We evaluated internal consistency, test-retest reliability, construct validity, and criterion validity of the ESS-CHAD in the sample of 145 children with a mean age of 14.58 (+/- 1.44), consisting of 53.1% females. Confirmatory factor analysis showed an 8-item unidimensional structure of the scale. Cronbach's alpha was 0.74; the correlation coefficients for test-retest reliability and criterion validity were 0.96 and 0.85, respectively (p's< .05). Our study presented the first evidence to establish the validity and reliability of the ESS-CHAD for Turkish children aged 12 - 18 years.
