Background: The aim of the present research was to develop a short measure for the five-factor model personality traits, which allows scores free of social desirability and acquiescence effects to be obtained. Method: Scales were created using recently developed methods to control response bias effects in a sample of 3,838 participants from a wide age range. The scales were answered in person or on-line. Results: Exploratory and confirmatory factor analysis showed the expected five factor structure. Furthermore, the scales showed good psychometric properties in that they had good reliability, temporal stability and convergence with the widely used Big-Five measures. Conclusions: The test developed in the paper presents acceptable psychometric properties, and it is suitable for individuals up from 13 years old. Because the method used to control response bias means that scales’ scoring is based upon factorial scores instead of raw scores, we have also developed an internet public application that can be used to obtain these scores.

Desarrollo y validación de las Escalas de Evaluación Global de la Personalidad (OPERAS). Antecedentes:La presente investigación se centra en el desarrollo de una medida breve de los rasgos de personalidad del modelo de los cinco grandes factores que permita la obtención de puntuaciones libres de los sesgos de respuesta más habituales. Método: Para ello la escala se construyó utilizando técnicas desarrolladas recientemente para el control de la deseabilidad social y la aquiescencia y se aplicó a una muestra de 3.838 participantes en un amplio rango de edad. Los participantes respondieron a la misma presencial o virtualmente. Resultados: Tanto el análisis exploratorio como el confirmatorio mostraron la estructura esperada de cinco factores. Además, las diferentes subescalas mostraron una buena consistencia interna, estabilidad temporal y validez convergente con otras medidas ampliamente utilizadas en la evaluación de la personalidad. Conclusiones: El test desarrollado presenta propiedades psicométricas aceptables, y es adecuado para individuos a partir de 13 años. Debido a que el método utilizado para controlar los sesgos de respuesta precisa de la utilización de puntuaciones factoriales se ha desarrollado una aplicación pública de internet que puede ser utilizada para obtener dichas puntuaciones.
