Abstract

Background
Social and emotional difficulties have been identified as key factors in the development and maintenance of anorexia nervosa (AN). However, few studies have investigated the influence of comorbid psychopathology on social cognition. The aim of the current study was to examine perception of nonverbal communication and empathy in AN using ecologically valid, performance-based measures, and to explore associations with comorbid psychopathology (anxiety, depression, autism spectrum disorder (ASD) traits, alexithymia, and social anxiety).

Methods
In this cross-sectional study, the Multifaceted Empathy Test (MET) and the Mini Profile of Nonverbal Sensitivity (MiniPONS) were administered to 51 adults with AN, 51 recovered AN (REC), and 51 healthy controls (HCs). Comorbid psychopathological traits were assessed using self-report questionnaires and the Autism Diagnostic Observation Schedule – 2nd edition (ADOS-2).

Results
Individuals with AN showed reduced affective empathy to positive stimuli compared to HCs, and a trend towards lower vocal prosody recognition scores relative to REC. Around a quarter of AN and REC scored above the clinical cut-off for ASD on the ADOS-2, and high ASD symptoms predicted lower cognitive and affective empathy scores.

Limitations
The study is cross-sectional, future research would benefit from examining social-cognition performance and comorbid psychopathology longitudinally.

Conclusions
The findings highlight the importance of ASD symptoms in empathy dysfunction in those with a lifetime history of AN. Future research should explore whether treatment adaptations to accommodate for differences in social-cognitive abilities may be helpful in the treatment of AN.
