Recommended For:

This course is recommended for researchers and health care professionals interested in the impact of the proposed changes to the binge eating frequency criterion and duration in DSM-5.

Course Objectives:

1. Describe the limitations of the current DSM-IV binge eating frequency and duration criteria.

2. Demonstrate how lifetime prevalence of bulimia nervosa and binge eating disorder changes across a range of binge eating frequency thresholds in a large population-based sample.

3. Explain the likely impact of the proposed DSM-5 changes to the binge eating frequency and duration criterion on the healthcare system based on the findings from this study.
