Predictive Validity of Purging Disorder: A 10‐Year Follow‐Up Study Comparing Prevalence and Psychosocial Outcomes for Alternative Criteria Sets

Key Points

The study highlights the relevance of specifying diagnostic criteria for purging disorder to enhance predictive validity.
Key metrics indicate that specific criteria, including self-induced vomiting and laxative use, occur weekly on average.
Assessment of purging disorder used a longitudinal design to evaluate psychosocial outcomes over a 10-year period.
Findings support improved diagnostic reliability in purging disorder, emphasizing better screening methods for treatment.

Abstract

Together, findings support defining PD through self-induced vomiting, laxative use, or diuretic use to influence body shape or weight, on average, at least once per week. Specifying diagnostic criteria for PD that demonstrate evidence of concurrent and predictive validity will contribute to improved diagnostic reliability, screening, assessment, and support future research efforts to improve treatment.
