A Bayesian network model was developed in the training sample, modelling early changes (sessions 1\u20134) and interactions among symptoms measured by the Eating Disorder Examination Questionnaire (EDE\u2010Q). A variable selection approach was applied to include only the most important variables in the model (i.e., reliable predictors of recovery). The trained model was externally validated by applying it to predict post\u2010treatment recovery status in the test sample.

The model was reliable in predicting recovery status and showed good generalisability to a test sample (training AUC\u00a0=\u00a00.81 vs. test AUC = 0.77). Early changes in six areas (ranked by importance) reliably predict recovery after therapy: [1] avoidance of body exposure; [2] feelings of \u2018fatness\u2019; [3] preoccupation with food, eating or calories; [4] fear of losing control over eating; [5] dissatisfaction with body shape; [6] dietary rules.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>The identification of early response domains associated with eventual recovery could help to inform targeted interventions strategies for patients with eating disorders.
