title: [Assessment of emotional reactivity to food images in bulimia nervosa].
abstract: The aim of the study was to assess the influence on reactivity to food images of the following variables: craving-trait, positive or negative mood state, and food restriction. Emotional modulation of the defense startle reflex (RMS) was assessed in 26 women at risk of suffering from bulimia nervosa; they were assigned one of to two groups: high craving-trait and low craving-trait. Before the test, positive or negative mood and restriction vs. non-restriction states were induced in each of the groups. Skin conductance response (SCR) and electromyogram activity from the orbiculari oculi region were recorded after the auditory stimuli; questionnaires such as Food Craving Trait Questionnaire (FCQ-T) and the Self-assessment Manikin (SAM) were used. Results showed that negative affect produced a negative valence of food images, more arousal, and more loss of control, as well as higher SCRs. Subjects with low FCQ-T levels reduced their RMS to food images as a consequence of experiencing positive emotions; when emotions were negative, their RMS increased.
