Eating Disorders: Anorexia Nervosa, Bulimia Nervosa, and Binge Eating Disorder
Bibliographic record
Abstract
This chapter addresses anorexia nervosa, bulimia nervosa, and the various eating syndromes that are classified as eating disorders not otherwise specified, providing an up-to-date discussion on phenomenology (including eating-specific and comorbid features), epidemiology, and etiology. In the eating disorders, interactive effects involving environmental risks (e.g., cultural inducements toward excessive dieting or overachievement) and constitutional susceptibilities in vulnerable individuals (e.g., heritable propensities toward appetitive dysregulation, affective instability, or excessive anxiety) are highly evident, perhaps more so than in many other mental-health problems. As a result, the eating disorders encourage us to think in terms of multiple determinants and maintaining factors. A main organizing concept throughout this chapter is a multidimensional etiological concept that integrates findings from biological, psychological, family-developmental, and cross-cultural studies and, more importantly, from studies on constitution x environment interactions. The chapter also provides a heuristic for differentiating factors that constitute disorder-specific risks from those that contribute (and that may explain comorbid traits, like marked impulsivity or affective instability) without having specific causal roles.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
