    Los objetivos de este estudio fueron examinar la validez y la fiabilidad de la versión española de la “Escala de comparación de la apariencia física-revisada” (Physical Appearance Comparison Scale-Revised; PACS-R) y evaluar su capacidad predictiva de la insatisfacción corporal y las alteraciones alimentarias en una muestra comunitaria española. 1405 participantes (83,6% mujeres; de entre 14 y 64 años) completaron la PACS-R y también medidas de imagen corporal, alteraciones alimentarias, influencias socioculturales relacionadas con la apariencia física, autoestima y comparación social. Los análisis factoriales exploratorio y confirmatorio apoyaron la estructura unidimensional original para la versión española de 11 ítems de la PACS-R. Las mujeres mostraron puntuaciones significativamente más elevadas que los hombres. Se halló una consistencia interna excelente, buena fiabilidad test-retest y buena validez convergente. Los análisis de regresión demostraron la utilidad de la escala para predecir la insatisfacción corporal y las alteraciones alimentarias tanto en hombres como en mujeres. Las excelentes propiedades psicométricas de la PACS-R la convierten en una herramienta útil para medir las comparaciones de la apariencia física en personas de habla española.

    The objectives of this study were to examine the validity and reliability of the Spanish version of the Physical Appearance Comparison Scale-Revised (PACS-R) and to assess its ability to predict body dissatisfaction and disordered eating in a community sample in Spain. A total of 1405 participants (83.6% women; aged 14-64) completed the Spanish PACS-R along with measures of body image, eating disturbances, appearance-related sociocultural influences, self-esteem and social comparison. Exploratory and confirmatory factor analyses supported the original one-dimensional factor structure for the 11-item Spanish version of the PACS-R. Women had significantly higher PACS-R scores than men. Internal consistency of the measure was excellent, and results showed good test-retest reliability and convergent validity in men and women. Regression analyses demonstrated the utility of the scale in predicting body dissatisfaction and disordered eating in both genders. Results suggest that the Spanish PACS-R has excellent psychometric properties, therefore it might be a useful tool to measure appearance comparisons among Spanish speaking populations.
