Impaired social cognition in anorexia nervosa patients

BACKGROUND The purpose of this study was to investigate the characteristics of social cognition in patients with anorexia nervosa (AN). METHODS Eighteen female patients with AN (mean age =35.4±8.6 years) and 18 female healthy controls (HC) (mean age =32.8±9.4 years) participated in the study. Their social cognition was assessed with the Social Cognition Screening Questionnaire (SCSQ). RESULTS The results showed that total score of the SCSQ and scores of theory of mind and metacognition were significantly lower in AN group than those in HC group. Moreover, significant differences in theory of mind, metacognition, and total score of the SCSQ remained when the effects of depression, anxiety, and starvation were eliminated statistically. CONCLUSION These results suggest that patients with AN may have difficulty inferring other people's intention and also monitoring and evaluating their own cognitive activities. Therefore, these features may explain some aspects of the pathology of AN.
