Background. The aim of this study was to assess the relationship among variables measuring eating disorder and general psychopathology, quality of life, body mass index (BMI), weight loss expectations and internalized weight-stigma in individuals with obesity, using a network analysis. Methods. Treatment seeking patients with obesity were consecutively recruited in a rehabilitative residential treatment program for severe obesity. Each patient completed the following questionnaires: EDE-Q, SCL-90), ORWELL 97) and WBIS. Moreover, current BMI was measured, and maximum acceptable and dream BMI were assessed. Results. The sample included 996 patients with obesity (age 52.3 (SD=16.0) years; BMI 41.8 (SD=7.8) kg/m2; 65.7% females; 52.2%). The network analysis showed that interpersonal sensitivity and shape concern, but also quality of life and internalized weight-stigma were the most central and highly interconnected nodes in the network. On the contrary, objective binge-eating episodes and dietary restraint were the most peripheral and least connected nodes. Eating disorder and general psychopathology formed two clearly separated clusters. No difference in the network structure was found between men and women. Conclusions. The pattern of network node connections supports the design and evaluation of personalized interventions addressing interpersonal sensitivity, shape concern and internalized weight-stigma.
