Beliefs and expectations regarding etiology, treatment and outcome in bulimia nervosa
Bibliographic record
Abstract
OBJECTIVE: To examine pretreatment client beliefs and expectations about the causes of bulimia nervosa (BN), and helpfulness of treatment. The association between outcome expectations, pretreatment characteristics, and treatment outcome was also tested. METHOD: 76 BN clients completed a questionnaire assessing beliefs and expectations before participating in a randomized treatment trial. RESULTS: Clients attributed their BN to problems of dysphoria, low self-esteem, perfectionism, and weight preoccupation. They also anticipated a wide array of therapeutic modalities to be helpful, and expected to make changes within 7 weeks of treatment. Surprisingly, outcome expectations were not related to treatment response. Clients who were identified as treatment optimists were more likely to be older, have a longer duration of illness, and greater pretreatment depression and BN symptomatology. DISCUSSION: These results are discussed in the context of the transtheoretical model, suggesting that veteran BN clients who experience greater complications are less ambivalent and more hopeful about change.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
