Résumé
In order to experimentally asses the role of socio-emotional problems in Eating Disorder (ED) psychopathology, we have measured affective states and ED-related attitudes in response to an acute psychosocial stress and their relationships with interpersonal sensitivity in people with Anorexia Nervosa (AN) and Bulimia Nervosa (BN). Twenty-one women with AN, 21 with BN and 27 healthy women underwent an acute psycho-social challenge, the Trier Social Stress Test. Anxiety feelings, hunger perception, amount of desired food and body dissatisfaction were measured throughout the experimental procedure. The relationships between these variables and with interpersonal sensitivity measures were explored through Pearson's correlation and mediation analyses. Stress-induced anxiety was increased in people with EDs. People with AN showed reduced hunger perception, decreased desire for food and a negative association between anxiety feelings and desire for food. In people with EDs, baseline ineffectiveness predicted post-stress body dissatisfaction through the mediation of post-stress anxiety levels. The relatively low sample size and the lack of an experimental control condition are the main limitations of the study. The present findings show, for the first time, the relationships between socio-emotional distress and ED-related attitudes in people with EDs, providing experimental support to the interpersonal model of EDs. This gives empirical evidence to treatments targeting interpersonal problems in EDs.

BACKGROUND
In order to experimentally asses the role of socio-emotional problems in Eating Disorder (ED) psychopathology, we have measured affective states and ED-related attitudes in response to an acute psychosocial stress and their relationships with interpersonal sensitivity in people with Anorexia Nervosa (AN) and Bulimia Nervosa (BN).
METHODS
Twenty-one women with AN, 21 with BN and 27 healthy women underwent an acute psycho-social challenge, the Trier Social Stress Test. Anxiety feelings, hunger perception, amount of desired food and body dissatisfaction were measured throughout the experimental procedure. The relationships between these variables and with interpersonal sensitivity measures were explored through Pearson's correlation and mediation analyses.
RESULTS
Stress-induced anxiety was increased in people with EDs. People with AN showed reduced hunger perception, decreased desire for food and a negative association between anxiety feelings and desire for food. In people with EDs, baseline ineffectiveness predicted post-stress body dissatisfaction through the mediation of post-stress anxiety levels.
LIMITATIONS
The relatively low sample size and the lack of an experimental control condition are the main limitations of the study.
CONCLUSIONS
The present findings show, for the first time, the relationships between socio-emotional distress and ED-related attitudes in people with EDs, providing experimental support to the interpersonal model of EDs. This gives empirical evidence to treatments targeting interpersonal problems in EDs.
