Mapping Heterogeneity in Psychological Risk Among University Students Using Explainable Machine Learning
This study pioneers a 'Predict-Explain-Discover' framework combining XAI (TreeSHAP) with unsupervised learning (GMM) to uncover three distinct psychological risk subtypes among university students: Academic-Driven, Socio-Emotional, and Internal Regulatory. Moving beyond binary risk classification, this approach enables precision interventions tailored to specific mechanistic drivers, representing a significant advance in computational mental health and personalized student support.

Bridging RDoC with Data-Driven Phenotyping
Our framework aligns with the Research Domain Criteria (RDoC) by moving beyond broad symptom-based categories to a multidimensional understanding of psychological dysfunction. By clustering in the SHAP attribution space, we identify distinct psychological drivers, offering a mathematically sound bridge to the tripartite model of student distress and transforming classifiers into interpretable diagnostic lenses.

From Generic to Precision Interventions
The identification of Academic-Driven, Socio-Emotional, and Internal Regulatory risk subtypes enables a critical shift in student mental health management. Instead of one-size-fits-all approaches, universities can deploy tailored interventions. For instance, academically-driven students may benefit from cognitive restructuring, while socio-emotional risks could be addressed through social skills training. Internal regulatory deficits might require mindfulness or physiological regulation techniques, ensuring support directly targets specific predictive drivers.

Your Path to Precision Mental Health Support
A structured roadmap for integrating the 'Predict-Explain-Discover' framework into your university's student well-being initiatives.
Phase 1: Data Integration & Model Training
Consolidate existing student textual data (reflections, mood descriptions) and other behavioral indicators. Train and validate the high-performance XGBoost classifier to identify at-risk students.
Phase 2: SHAP Attribution & Subtype Discovery
Apply TreeSHAP to decompose model predictions into feature contributions for each student. Utilize GMM clustering on SHAP values to discover distinct psychological risk subtypes (Academic-Driven, Socio-Emotional, Internal Regulatory).
Phase 3: Tailored Intervention Strategy Design
Based on the identified subtypes and their mechanistic drivers, develop personalized intervention strategies. Collaborate with counseling services to integrate these insights into existing support programs.
Phase 4: Pilot Program & Longitudinal Evaluation
Implement a pilot program with targeted interventions for each subtype. Establish metrics for longitudinal evaluation to assess the effectiveness and impact on student well-being outcomes.
