Self-assessment of empathy uncovers defective self-awareness in mild cognitive impairment

Objective: Self-assessment scales are broadly used to evaluate empathy in neurological patients, but it is conceivable that some discrepancy with caregiver evaluation may emerge as consequence of reduced self-awareness. The aim of the present study was to verify the presence of discrepancies in the self-assessment of empathy in subjects with mild cognitive impairment (MCI) and to explore their neural correlates. Method: Twenty MCI patients and 38 healthy controls (HCs) underwent the Interpersonal Reactivity Index (IRI), exploring the following four aspects of empathy: perspective taking (PT), fantasy, empathic concern, and personal distress. The questionnaire was administered in two modalities: self-administered, and administered to an informant, and the scores were compared. The correlation between discrepancies and regional cortical thickness was assessed. Results: The self-administered version of IRI showed higher PT scores in MCI as compared to HC (p = .017), with no differences detected in the other subscales. The difference between the scores obtained in the self-administered and in the informant-administered IRI-PT was significantly higher in MCI than in HCs (p = .006). Conclusion: The self-assessment of empathy in subjects with MCI may be misleading because of a tendency toward an overestimation of the PT ability, typically considered as a cognitive component of empathy. Our results may reflect a particular aspect of reduced self-awareness in MCI subjects. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
