Spanish Version of the Everyday Discrimination Scale (EDS-E): Factorial Structure and Scale Invariance in Spanish Adolescents

<b>Background/Objectives:</b> Discrimination is a phenomenon of special relevance in adolescence, as this is a key period in the development of young people, so measures that accurately and reliably assess it are essential. The aim of this research is to study the psychometric properties of the Spanish version of the Everyday Discrimination Scale in a sample of Spanish adolescents. <b>Methods:</b> The scale was applied to 1000 adolescents using Computer Assistance Web Interview (CAWI) methodology by means of a stratified random sampling by age, gender and territorial distribution. <b>Results:</b> The results reveal an unifactorial structure of the scale, with adequate measures of reliability and validity that confirm that it is a suitable instrument for assessing everyday discrimination in this population. <b>Conclusions</b>: This study has implications for understanding the experiences of discrimination in adolescents and for developing interventions to reduce discrimination and promote equality. Limitations and implications for the future are also discussed.
