Psicothema was founded in Asturias (northern Spain) in 1989, and is published jointly by the Psychology Faculty of the University of Oviedo and the Psychological Association of the Principality of Asturias (Colegio Oficial de Psicología del Principado de Asturias).
We currently publish four issues per year, which accounts for some 100 articles annually. We admit work from both the basic and applied research fields, and from all areas of Psychology, all manuscripts being anonymously reviewed prior to publication.

Se evalúa el funcionamiento y propiedades de medida de la versión española de la escala de Locus de Control de Rotter; dicha evaluación utiliza un nuevo enfoque basado en la teoría de respuesta al ítem. Nuestro procedimiento permite: (a) detectar el impacto de los sesgos de respuesta (aquiescencia y deseabilidad social); (b) evaluar de forma clara la dimensionalidad y estructura del test; (c) evaluar las posibles causas del deficiente funcionamiento de algunos ítems; y (d) incrementar la precisión de la medida. Globalmente, los resultados no contradicen lo obtenido en estudios previos, pero permiten matizar algunas de las críticas que ha recibido la escala. Se proponen algunas recomendaciones para su uso.
An IRT assessment of Rotter’s I-E scale: A new approach and some considerations. This study assessed the functioning and measurement properties of Rotter’s Locus of Control Scale in its Spanish version by using a new approach based on Item Response Theory. Our procedure allows us: (a) to detect the impact of response biases (acquiescence and social desirability); (b) to evaluate clearly the test dimensionality and structure; (c) to evaluate and understand the causes of some items’ inefficiency; and (d) to increase measurement precision. Globally, the results do not contradict those obtained in previous research, but allow some of the criticisms the scale had received to be qualified. Some recommendations for use are proposed.
