ESCALA DE EXPERIENCIAS DE DISCRIMINACIÓN: CONSISTENCIA Y ESTRUCTURA INTERNA EN ESTUDIANTES DE MEDICINA (Experiences of Discrimination Scale: Internal consistency and structure in medical students)
Resumen
El objetivo fue estimar la consistencia y estructura interna de la Escala de Experiencias de Discriminación (EED) en estudiantes de medicina de Bucaramanga, Colombia. Se realizó un estudio de validación con 361 estudiantes, entre 18 y 30 años, y 59,7%, mujeres. La EED agrupa dos escalas distintas, discriminación general (EED-G) y preocupación por discriminación (EED-P). Se determinó alfa de Cronbach, omega de McDonald y estructura interna (análisis factorial exploratorio). La EED-G mostró alfa de Cronbach de 0,88 y omega de McDonald de 0,89; y la EED-P, 0,80 para ambos coeficientes. La EED-G presentó un factor que explicó 52,9% de la varianza; y EED-P, una dimensión fue responsable del 62,5% de la varianza. Se concluye que la EED presenta buen desempeño psicométrico, EED-G y EED-P son dos escalas unidimensionales con alta consistencia interna.

Abstract
The objective was to estimate the internal consistency and structure of the Experiences of Discrimination Scale (EDS) in medical students from Bucaramanga, Colombia. A validation study was conducted. A total of 361 student participated, aged between 18 to 30, and 59.7% were women. The EED includes two separated scales, overall discrimination (O-EDS) and concerns about discrimination (W-EDS). Cronbach alpha, McDonald omega and internal structure (exploratory factor analysis) were determined. The O-EDS showed Cronbach alpha of 0.88 and McDonald omega, 0.89; and W-EDS, showed 0.80 for both coefficients. The O-EDS consists in a factor that explained 52.9% of the variance; and W-EDS one dimension was responsible of 62.5% of the variance. It is concluded that EDS shows an appropriate psychometric performance, both W-EDS and O-EDS are one-dimensional scales with high internal consistency.
Keywords: Experiences of Discrimination Scale, Validity, Test Validity, Test Reliability, Reproducibility of Results, Validation Studies, Psychometrics, Medical Students, Racism.
