Abstract
OBJECTIVES: DSM-5 changes for eating disorders (EDs) aimed to reduce preponderance of non-specified cases and increase validity of specific diagnoses. The objectives were to estimate the combined effect of changes on prevalence of EDs in adolescents and examine validity of diagnostic groupings. METHOD: A total of 3043 adolescents (1254 boys and 1789 girls, Mage = 14.19 years, SD = 1.61) completed self-report questionnaires including the Eating Disorder Diagnostic Scale. RESULTS: Prevalence of full-threshold EDs increased from 1.8% (DSM-IV) to 3.7% (DSM-5), with a higher prevalence of bulimia nervosa (1.6%) and the addition of the diagnosis of purging disorder (1.4%); prevalence of binge eating disorder was unchanged (0.5%), and non-specified cases decreased from 5.1% (DSM-IV) to 3.4% (DSM-5). Validation analyses demonstrated that DSM-5 ED subgroups better captured variance in psychopathology than DSM-IV subgroups. DISCUSSION: Findings extend results from previous prevalence and validation studies into the adolescent age range. Improved diagnostic categories should facilitate identification of EDs and indicate targeted treatments.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
