Overview

AI-generated summary, not a substitute for reading the source.

This study compares bulimia nervosa severity classifications based on shape/weight overvaluation against DSM-5 criteria using compensatory behavior frequency in a sample of 1,017 treatment-seeking individuals. The authors utilized structural equation modeling trees to identify five severity subgroups defined by overvaluation levels and assessed their association with clinical characteristics such as depression and anxiety. Results indicate that the overvaluation-based model explains significantly more variance in these symptoms than the DSM-5 scheme or purging method indicators.
