Machine Learning-XGBoost Analysis of Subjective Well-being Among Chronic Hepatitis B Patients
This study leveraged the XGBoost machine learning algorithm to analyze objective social support, subjective social support, social participation, and self-efficacy as predictors of subjective well-being in 253 chronic hepatitis B (CHB) patients. Achieving a classification accuracy of 98.04%, the model identified self-efficacy as the most crucial predictive factor. The findings highlight the importance of targeted psychological interventions focused on enhancing self-efficacy and social support for CHB patients, demonstrating the significant utility of AI algorithms in health psychology research.

XGBoost Technical Advantages
This research highlights the transformative potential of AI algorithms, particularly XGBoost, in healthcare prediction. Moving beyond traditional statistical models, AI offers superior prediction accuracy and generalizability, making it ideal for complex, real-world data in clinical settings. The study demonstrates how AI can model nonlinear interactions and multidimensional patterns inherent in health data, providing precise and robust insights for patient management.
The study identifies several critical psychosocial factors influencing subjective well-being in CHB patients, including objective social support, subjective social support, social participation, and self-efficacy. Notably, self-efficacy emerged as the most crucial predictive factor, underscoring its significant role in coping with chronic illness. These findings align with established psychological models and emphasize the need for targeted interventions.
XGBoost is an advanced gradient boosting algorithm renowned for its high precision, versatility, and stability. It builds decision trees sequentially, correcting errors from previous iterations. The algorithm incorporates regularization terms to prevent overfitting, enhancing model robustness. This enables XGBoost to effectively handle complex interactions and high-dimensional data, outperforming many other machine learning methods in predictive tasks.

XGBoost: Superior Predictive Power for Healthcare
The XGBoost algorithm demonstrates exceptional performance in healthcare predictive analytics, achieving high precision and stability. Its optimized gradient boosting implementation iteratively corrects prediction errors, leading to robust models. A key advantage is its regularization mechanism, which effectively prevents overfitting, ensuring reliable results even with complex, heterogeneous datasets. This makes XGBoost particularly suited for sensitive applications like psychological screening in chronic disease management, where accuracy and generalizability are paramount. Compared to traditional models like Logistic Regression or SVM, XGBoost's ability to capture nonlinear interactions provides a significant edge, offering deeper insights into patient well-being factors.
