Overview

Network analysis reveals distinct symptom-level suicide risk pathways in anorexia versus bulimia nervosa, highlighting the need for diagnosis-specific risk assessment and interventions.

Key Points

  • To compare symptom-level network connections between eating disorder psychopathology and lifetime suicide attempts in female patients with anorexia nervosa versus bulimia nervosa.
  • Analyzed cross-sectional data from 865 female patients diagnosed with anorexia nervosa (n = 257) or bulimia nervosa (n = 608).
  • Assessed eating disorder psychopathology via the Eating Disorder Inventory-2, depressive symptoms via the Beck Depression Inventory, and lifetime suicide attempt history via diagnostic interview.
  • Estimated separate psychometric networks for each diagnosis and evaluated differences in overall network structure, global strength, and individual edge weights using network comparison procedures.
  • The anorexia nervosa network directly linked suicide attempts to depressive symptoms and multiple eating disorder dimensions, with the strongest edge connecting suicide attempts to bulimic symptoms.
  • The bulimia nervosa network connected suicide attempts directly to depressive symptoms, ineffectiveness, and impulse regulation, with the impulse regulation edge displaying the largest estimate.
  • Network comparison tests confirmed significant overall structural differences between diagnoses, with the suicide attempt to bulimic symptoms connection being significantly stronger in anorexia nervosa.
