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 Psicólogos 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.

Background: Deficits in information processing, sustained attention and social cognition have important implications for the daily functioning of people with schizophrenia. The present study analyzed the relationship between processing speed, sustained attention, social cognition, and functioning in clinically stable people with schizophrenia. Method: Ninety people with schizophrenia and 100 healthy controls completed a battery of measures to assess clinical symptoms, processing speed, sustained attention, social cognition, and functioning. GLMMs and SEM were used to assess the relationships between these variables. Results: People with schizophrenia had impaired performance in all cognitive outcomes compared to healthy controls. Processing speed and sustained attention, together in a latent variable, had a strong effect on functioning (Beta = 0.32; p < .05). However, social cognition had also a strong effect on functioning (Beta = 0.29; p <.001) in the mediation model, which exhibited better indices of fit than the model including neurocognition alone (e.g. RMSEAbasic = 0.131 and RMSEAmediator = 0.054). Conclusions: The mediating effect of social cognition on the relationship between processing speed, sustained attention, and functioning in people with schizophrenia suggests the importance of including both domains of neurocognition along with social cognition as treatment targets in rehabilitation interventions to optimize improvements in functioning in schizophrenia.

Antecedentes: Los déficits en el procesamiento de la información, la atención sostenida y la cognición social tienen implicaciones importantes para el funcionamiento diario de las personas con esquizofrenia. El presente estudio analizó la relación entre velocidad de procesamiento, atención sostenida, cognición social y funcionamiento en personas clínicamente estables con esquizofrenia. Método: Noventa personas con esquizofrenia y 100 controles sanos completaron una batería de pruebas para evaluar síntomas clínicos, velocidad de procesamiento, atención sostenida, cognición social y funcionamiento. Se utilizaron GLMM y SEM para evaluar las relaciones entre variables. Resultados: Las personas con esquizofrenia tuvieron un peor rendimiento en todos los resultados cognitivos. La velocidad de procesamiento y la atención sostenida, juntas en una variable latente, tuvieron un fuerte efecto sobre el funcionamiento (Beta = 0,32; p < 0,05). La cognición social también tuvo un fuerte efecto sobre el funcionamiento (Beta = 0,29; p < 0,001) en el modelo de mediación, que mostró mejores índices de ajuste que el modelo que incluía solo neurocognición (e.g. RMSEAbasic = 0.131 y RMSEAmediator = 0.054). Conclusiones: El efecto mediador de la cognición social sobre la relación entre la velocidad de procesamiento, la atención sostenida y el funcionamiento sugiere la importancia de incluir ambos dominios junto con la cognición social como objetivos de tratamiento en las intervenciones de rehabilitación.
