Cognitive behavioral therapy as an evidence-based treatment for bulimia nervosa
Bibliographic record
Abstract
Bulimia nervosa (BN) presents significant psychological, behavioural, and physical challenges, often co-occurring with psychiatric conditions such as depression, PTSD, and ADHD, which can worsen prognosis and psychosocial functioning. This narrative review explores the efficacy of cognitive-behavioural therapy for bulimia nervosa (CBT-BN) as an evidence-based treatment, contrasting its rapid symptom improvement with traditional approaches like psychoanalytic psychotherapy. Studies consistently show that CBT-BN offers substantial reductions in binge eating and purging within a short treatment duration, making it an efficient and effective intervention. Key to its success is the structured targeting of dietary restraint and cognitive distortions that drive the binge-purge cycle. Group CBT also emerges as a promising, cost-effective alternative with comparable efficacy to individual CBT, suggesting potential for broader accessibility. Despite the positive outcomes, access to specialized CBT-BN practitioners remains limited, underscoring the need for scalable models such as group therapy. This review highlights CBT-BN's potential as a comprehensive, impactful approach that addresses primary and secondary symptoms of BN and offers enduring benefits for affected individuals.

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.
