Feature selection used bootstrapped LASSO with permutation testing. Model performance was assessed by discrimination, calibration, and decision curve analysis. SHAP (SHapley Additive exPlanations) provided global and individual-level interpretability.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The XGBoost model achieved strong discrimination in external validation (AUC\u202f=\u202f0.859). In the internal test set, XGBoost outperformed logistic regression and other machine learning algorithms (AUC: 0.963 vs. 0.910 for logistic regression). SHAP analysis identified Effort-Reward Imbalance and Overcommitment as dominant predictors, and revealed a potential inflection point at approximately 65 weekly work hours, beyond which burnout risk escalated disproportionately in the SHAP analysis. Decision curve analysis confirmed net clinical benefit across threshold probabilities of 5 \u201365%. Individualized risk profiles were generated for actionable nurse management.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This externally validated, interpretable XGBoost-SHAP framework moves beyond population-averaged associations.

data-driven, precision prevention of burnout in radiology nurses.<\/jats:p>\n
