The aim of this study is to adapt the ESPA29 scale of parental socialization styles in adolescence to the Basque language. The study of its psychometric properties is based on the search for evidence of internal and external validity. The first focuses on the assessment of the dimensionality of the scale by means of exploratory factor analysis. The relationship between the dimensions of parental socialization styles and gender and age guarantee the external validity of the scale. The study of the equivalence of the adapted and original versions is based on the comparisons of the reliability coefficients and on factor congruence. The results allow us to conclude the equivalence of the two scales.El objetivo de este trabajo es adaptar al euskera la escala de estilos de socialización parental ESPA29. El estudio de sus propiedades psicométricas descansa en la búsqueda de evidencias internas y externas de validez. Las primeras se centran en la evaluación de la dimensionalidad de la escala a través de un análisis factorial exploratorio. La relación entre las distintas dimensiones de la socialización y las variables sexo y edad garantizan la validez externa de la escala. El estudio de equivalencia entre las versiones original y adaptada se apoya en la comparación entre los coeficientes de fiabilidad y de la congruencia factorial. Los resultados permiten concluir la equivalencia entre las dos escalas.
In this study the Eating Disorder Inventory-3 was adapted to Spanish and analyzed the internal psychometric properties of the test in a clinical sample of females with eating disorders. The results showed a high internal consistency of the scores as well as high temporal stability. The factor structure of the scale composites was analyzed using confirmatory factor analysis. The results supported the existence of a second-order structure beyond the psychological composites. The second-order factor showed high correlation with the factor related to eating disorders. Overall, the Spanish version of the EDI-3 showed good psychometric qualities in terms of internal consistency, temporal stability and internal structure.
