Résumé

Intervention for social cognition could be key to improving social functioning in patients with schizophrenia. A first step towards its clinical implementation involves interviewing patients about their subjective difficulties with social cognition as they experience them in the real world. The present study focused on the clinical subtypes classified by the discrepancies between the subjective difficulties in social cognition and actual cognitive impairment. A total of 131 outpatients with schizophrenia and 68 healthy controls were included. Objective measurement of social cognition was performed using a test battery covering four representative domains, and subjective difficulties were determined by a questionnaire covering the same domains. A two-step cluster analysis explored the potential classification of social cognition in patients with schizophrenia. There was little correlation between the objective performance on social cognition tasks and subjective difficulties in social cognition. The analysis yielded three clusters: the low-impact group (low objective impairment and low subjective difficulties), the unaware group (high objective impairment but low subjective difficulties), and the perceptive group (moderate objective impairment and high subjective difficulties). Positive, negative, and general symptoms were more severe in the two groups that showed impaired performance on the social cognition tasks (i.e., the unaware and perceptive groups) than those in the low-impact group. Neurocognition and functional capacity were the lowest in the unaware group, and social functioning was the lowest in the perceptive group. Awareness about the clinical subtypes of social cognition could serve as a guidepost for providing individualized, targeted interventions.
