New ML methodology uses circadian rhythm for depression screening

Researchers have developed a new methodology for depression screening and intervention using machine learning, focusing on circadian rhythm patterns. They introduced the Circadian Rhythm Score (CRS) to represent multi-domain daily behaviors in a unified index, which proved effective for depression screening. The framework, utilizing gradient-boosted trees and SHAP analysis, revealed nonlinear associations between circadian rhythm and depression risk. Experiments on the China Health and Retirement Longitudinal Study dataset showed robust screening performance with an ROC-AUC of 0.825 and identified actionable thresholds for exercise and napping.
