OBJECTIVE: Laxative abuse is common in patients with anorexia and bulimia nervosa and has been associated with longer duration of illness, suicide attempts, impulsivity, and greater eating and general psychopathology. We explored the extent to which laxative abuse was associated with specific psychopathological features across eating disorder subtypes.
METHODS: Participants were 1021 individuals from the multisite, International Price Foundation Genetic Studies. Axis I disorders, personality disorders and traits, and obsessive compulsive features were assessed.
RESULTS: Laxative abuse was associated with worse eating disorder and general psychopathology and higher prevalence of borderline personality disorder (BPD). Symptom level analyses revealed that specific features of BPD, including suicidality and self-harm, feelings of emptiness, and anger, were most strongly associated with laxative abuse.
CONCLUSIONS: The function of laxative abuse may differ across individuals with eating disorders, alternatively serving as a method of purging and a form of self-harm.
