Self-induced vomiting is adopted by people with a variety of eating disorders (ED) to control body shape and weight. We tested the prevalence, the associated features and the role on treatment outcome of self-induced vomiting in 152 ED patients consecutively admitted to an in-patient cognitive-behavioral treatment (CBT), based on the transdiagnostic CBT for ED. The Eating Disorder Examination, together with the Beck Depression Inventory, the State-Trait Anxiety Inventory and the Temperament and Character Inventory were recorded at entry and at end of treatment. Self-induced vomiting was reported in 35.5% of cases, and 21.1% had multiple purging with vomiting. Individuals with vomiting and those with multiple purging had significantly higher BMI and a higher frequency of bulimic episodes, but multiple purging was also characterized by higher levels of depression, longer ED duration, more severe ED psychopathology and lower self-directness. Individuals with vomiting had higher eating concern and novelty seeking compared with those without purging behaviors. However, the three groups had similar dropout rates and outcomes in response to in-patient CBT.

Abstract
Self-induced vomiting is adopted by people with a variety of eating disorders (ED) to control body shape and weight. We tested the prevalence, the associated features and the role on treatment outcome of self-induced vomiting in 152 ED patients consecutively admitted to an in-patient cognitive-behavioral treatment (CBT), based on the transdiagnostic CBT for ED. The Eating Disorder Examination, together with the Beck Depression Inventory, the State-Trait Anxiety Inventory and the Temperament and Character Inventory were recorded at entry and at end of treatment. Self-induced vomiting was reported in 35.5% of cases, and 21.1% had multiple purging with vomiting. Individuals with vomiting and those with multiple purging had significantly higher BMI and a higher frequency of bulimic episodes, but multiple purging was also characterized by higher levels of depression, longer ED duration, more severe ED psychopathology and lower self-directness. Individuals with vomiting had higher eating concern and novelty seeking compared with those without purging behaviors. However, the three groups had similar dropout rates and outcomes in response to in-patient CBT.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
