“…A wide range of anomalies in social-emotional processing and reactivity to emotional stimuli have been documented in people with acute AN (Bora & Köse, 2016;Caglar-Nazali et al, 2014;Davies et al, 2016). Furthermore, longitudinal cohort studies have reported that difficulties in social cognition and social communication at admission are important predictors of poor treatment outcome at 3-to 18-year follow-up (Nielsen et al, 2015;Speranza, Loas, Wallier, & Corcos, 2007). Thus, these difficulties may contribute to the maintenance of the illness and further understanding of these processes is of importance.…”

A B S T R A C TBackground: People with anorexia nervosa (AN) have difficulties in a wide range of social-emotional processes. Previous work suggests atypical involvement of the prefrontal cortex (PFC), amygdala, insula, and fusiform gyri during social-emotional processing in AN. Methods: Twenty women with AN and twenty healthy comparison (HC) women were presented with happy, fearful, and neutral faces during a functional magnetic resonance imaging study. Group differences were investigated in the following regions of interest: lateral PFC, amygdala, insula, and fusiform gyri. Results: The HC participants showed significantly increased recruitment of the ventrolateral PFC and amygdala in the fearful > neutral contrast relative to the AN participants. The AN participants showed a significantly increased recruitment of a small cluster in the right posterior insula in the happy > neutral contrast. Conclusions: These findings are in line with the hypothesis that people with AN have a blunted response to negative and atypical exaggerated response to positive emotionally provoking stimuli.

“…These factors are likely not disorder-specific for AN (for instance, a possible overlapping between AN and autism spectrum disorders has been suggested), nonetheless in people with AN they may interfere with the healing process (Oldershaw, Hambrook, Tchanturia, Treasure, Schmidt, 2010). For instance, a 3-year longitudinal study (Speranza, Loas, Wallier, Corcos, 2007), found the Difficulty Identifying Feelings factor of the Toronto Alexithymia Scale significantly predicted treatment outcome, independent of depressive symptoms and ED severity.…”

Alexithymia, empathy, emotion identification and social inference in anorexia nervosa: A case-control study

Alexithymia, difficulties in facial emotion recognition, poor socio-relational skills are typical of Anorexia Nervosa (AN). We assessed patients with AN and healthy controls (HCs) with mixed stimuli: questionnaires (Toronto Alexithymia Scale-TAS, Interpersonal Reactivity Index-IRI), photographs (Facial Emotion Identification Test-FEIT) and dynamic images (The Awareness of Social Inference Test-TASIT). TAS and IRI Personal Distress (PD) were higher in AN than HCs.Few or no differences emerged at the FEIT and TASIT, respectively. Despite higher levels of alexithymia, patients with AN seem to properly acknowledge others' emotions while being inhibited in the expression of their own.

“…proposed that socio-emotional difficulties may contribute to the maintenance of the eating disorder psychopathology Schmidt and Treasure, 2006;Speranza et al, 2007) and in the case of AN, that eating disorder symptoms function, in part, to help the individual cope with aversive emotional states (Wildes et al, 2010).…”

first and second authors contributed equally to this publication  AN showed Duchenne smiles for shorter durations than BN and HC participants. AN participants' Duchenne smiles were less intense than those of BN and HC. Reduced Duchenne smile was related to low BMI, and use of medication. Results provide further evidence of difficulties in emotion processing in AN. AbstractA large body of research has associated Eating Disorders with difficulties in socioemotional functioning and it has been argued that they may serve to maintain the illness. This study aimed to explore facial expressions of positive emotions in individuals with Anorexia Nervosa (AN) and Bulimia Nervosa (BN) compared to healthy controls (HC), through an examination of the Duchenne smile (DS), which has been associated with feelings of enjoyment, amusement and happiness . Sixty participants (AN=20; BN=20; HC=20) were videotaped while watching a humorous film clip. The duration and intensity of DS were subsequently analysed using the Facial Action Coding System (FACS) (Ekman and Friesen, 2003). Participants with AN displayed DS for shorter durations than BN and HC participants, and their DS had lower intensity. In the clinical groups, lower duration and intensity of DS were associated with lower BMI, and use of psychotropic medication.The study is the first to explore DS in people with eating disorders, providing further evidence of difficulties in the socio-emotional domain in people with AN.
