BACKGROUND: Emotional difficulties are common among individuals with Eating Disorders (EDs). Following Panksepp's theoretical model, which conceptualises primary emotional systems as the evolutionary foundation of personality, this study aimed to identify distinct profiles of primary emotional systems within a clinical eating disorder (ED) sample. It further examined differences in sociodemographic, clinical, and psychopathological characteristics across profiles, as well as associations between clinical features and profile membership.
METHODS: In this cross-sectional study, data were obtained from the Regional Centre for ED registry at the University Hospital of Verona. Measures included the Affective Neuroscience Personality scales, the Eating Disorder Examination, the Symptom CheckList-90-Revised, the Life Stressor Checklist-Revised, and the Impact of Event Scale-Revised. A Latent Profile Analysis was conducted, followed by inferential analyses.
RESULTS: Among 122 patients, three profiles emerged: (1) high FEAR and SADNESS, and low SEEKING and PLAY; (2) low negative primary emotional systems and CARE; (3) high positive primary emotional systems and high SADNESS and ANGER. Profiles differed by age, sex, illness duration, trauma burden, depressive-anxiety symptoms, and ED severity.
DISCUSSION: Findings revealed emotional heterogeneity among ED patients, underscoring the importance of considering individual emotional differences in treatment planning. Study limitations and directions for future research are discussed.
