Considering the executive functions as a transdiagnostic process in ED and obesity could provide explanations for the inability to regulate food intake, present in both ED and obese patients. Implications of these executive impairments in the development and maintenance of ED and obesity are discussed.

Abstract:Cognitive remediation and emotion skills training was initially designed by the Tchanturia group for individual intervention in patients with eating disorders. The purpose of the present study is to present its adaptation to patients with obesity in group format. It is structured in 8 weekly sessions that work on central executive functions, the relation between emotion and thought, and emotion regulation in oneself and others. In addition, we present the preliminary results of its application to a group of 5 participants with morbid obesity to assess its possible effi cacy. The results indicate that, after the intervention, the patients showed improvement in their cognitive and emotional skills, as well as in their behaviors related to eating and weight. This program can be a useful complementary intervention in the initial stages of obesity treatment.Keywords: CREST; cognitive remediation; emotion; eating disorders; obesity.Resumen: El entrenamiento en remediación cognitiva y habilidades emocionales fue diseñado inicialmente por el grupo de Tchanturia para la intervención individual de pacientes con trastornos alimentarios. El objetivo del presente trabajo es exponer su adaptación a pacientes con obesidad en formato grupal. Se estructura en 8 sesiones semanales en las que se trabaja funciones de ejecutivo central, la relación entre emoción y pensamiento, y el manejo emocional en un mismo y en los demás. Además, presentamos los resultados preliminares de su aplicación a un grupo de 5 participantes con obesidad mórbida con el fi n de valorar su posible efi cacia. Los resultados indican que tras la intervención, las pacientes mostraron una mejoría en sus habilidades cognitivas y emocionales, así como en las conductas relacionadas con la alimentación y el peso. Este programa puede ser una intervención útil complemento del tratamiento de la obesidad en sus fases iniciales.

Eating disorders (ED) are associated with cognitive and emotional impairments. Cognitive and Emotional Remediation Skill Training (CREST) was developed as an intervention program targeting patients' thinking styles and their skills in recognizing and managing emotions. AIM: to analyze the effects of the CREST intervention in a group format in females with ED. METHOD: eight females underwent a CREST program (eight 90-minute sessions) targeting cognitive (central coherence, set shifting, problem solving) and emotional (recognizing emotions, managing emotions) difficulties. It was assessed cognitive flexibility (Wisconsin Card Sorting Test), decision-making (Iowa Gambling Task), central coherence (Group embedded Figures Test), alexithymia (Toronto Alexithymia Scale), affect (Positive and Negative Affect Schedule), ED symptomatology (Eating Attitudes Test). RESULTS: Results showed improvements in cognitive flexibility, decision-making, and central coherence, a decrease in depression, anxiety, negative affect, and alexithymia, and an improvement in quality of life. CONCLUSION: The results of this study on patients with ED suggest that the CREST can reduce ED symptomatology and could increase adherence to psychological treatments.
