Trait‐defined eating‐disorder subtypes and history of childhood abuse
Bibliographic record
Abstract
OBJECTIVE: In participants with eating disorders (EDs), prior physical or sexual abuse has been associated with increased likelihood of impulsivity and affective instability. However, previous studies among participants with eating disorders have not systematically explored relationships between empirically derived, personality-trait-based classes, on the one hand, and likelihood of exposure to either childhood sexual or physical abuse, on the other. METHOD: We assessed multiple psychopathological traits, eating symptoms, and history of abuse in 185 women with an ED and 93 with no ED. RESULTS: A latent class analysis, conducted using psychopathological-trait measures, yielded latent classes of participants with eating disorders fitting the descriptors "dissocial/impulsive," "inhibited/compulsive," and "low psychopathology." ED was generally associated with increased risk of childhood sexual abuse, but the dissocial/impulsive characteristic corresponded with a unique likelihood of physical abuse and especially high rates of sexual abuse. DISCUSSION: Observed associations between different forms of childhood abuse and trait-defined ED variants help inform models on the development of eating disorders and of psychopathological traits that often accompany them.

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.
