Abstract

fetched live from OpenAlex

Posttraumatic stress disorder (PTSD) and eating disorders (EDs) frequently co-occur, with PTSD potentially worsening ED treatment outcomes. Integrated and concurrent interventions that treat both conditions together have been recommended, but no best practices exist. This case series of nine patients provides preliminary data on Written Exposure Therapy (WET), a brief, low-resource PTSD intervention, delivered concurrently with inpatient or day hospital ED treatment. Results showed reductions in PTSD symptoms, with most patients experiencing clinically significant improvements. Changes in ED symptoms varied, but no patients experienced deterioration. These findings suggest WET is a promising, efficient method for treating PTSD alongside ED treatment, supporting the need for clinical trials to assess its acceptability and efficacy for ED-PTSD.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
