INFORMATION

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.

Cue-exposure software for the treatment of bulimia nervosa and binge eating disorder

Background: Cue-exposure therapy (CET) has proven its efficacy in treating patients with bulimia nervosa and binge eating disorder who are resistant to standard treatment. Furthermore, incorporating virtual reality (VR) technology is increasingly considered a valid exposure method that may help to increase the efficacy of standard treatments in a variety of eating disorders. Although immersive displays improve the beneficial effects, expensive technology is not always necessary. Method: We aimed to assess whether exposure to food related virtual environments could decrease food craving in a non-clinical sample. In addition, we specifically compared the effects of two VR systems (one non-immersive and one immersive) during CET. We therefore applied a one-session CET to 113 undergraduate students. Results: Decreased food craving was found during exposure to both VR environments compared with pre-treatment levels, supporting the efficacy of VR-CET in reducing food craving. We found no significant differences in craving between immersive and non-immersive systems. Conclusions: Low-cost non-immersive systems applied through 3D laptops can improve the accessibility of this technique. By reducing the costs and improving the usability, VR-CET on 3D laptops may become a viable option that can be readily applied in a greater range of clinical contexts.

Programa de exposición a señales para el tratamiento de la bulimia nerviosa y del trastorno por atracón. Antecedentes: la terapia de exposición a señales (TES) se ha mostrado eficaz en el tratamiento de pacientes con bulimia nerviosa y trastorno por atracón. Por otra parte, la incorporación de tecnologías de realidad virtual (RV) se considera cada vez más un método de exposición válido que puede ayudar a aumentar la eficacia de los tratamientos. Aunque los dispositivos inmersivos mejoran los efectos beneficiosos, no siempre es necesario el uso de tecnología costosa. Método: el objetivo de este estudio es evaluar si la exposición a entornos virtuales relacionados con la comida puede disminuir el deseo de comer en una muestra no clínica. Además, se comparan los efectos de dos sistemas (uno no inmersivo y otro inmersivo) durante la TES. Se aplicó un modelo de TES en una única sesión a 113 participantes. Resultados: los resultados indicaron una disminución del deseo de comer como efecto de la exposición. No se encontraron diferencias significativas entre los dos sistemas. Conclusiones: los resultados sugieren que con sistemas de bajo coste y alta facilidad de uso, la TES mediante RV puede llegar a ser una opción aplicable en un mayor rango de contextos clínicos.
