Abstract
Students, as future professionals and key players in social networks and community development, face various psychological challenges. Early detection and timely intervention can prevent the emergence of more serious issues. Therefore, aiming to provide an innovative framework for predicting students’ mental health, this study proposes an intelligent integration of multi-criteria decision-making (DEMATEL1), improved principal component analysis2, and machine learning techniques. First, based on a comprehensive dataset of student information and using DEMATEL technique, the complex structure of relationships between factors affecting students’ mental health is identified. Then, the target variable (mental health status) was extracted through improved principal component analysis. In the modeling phase, accordingly to comparing five machine learning algorithms, the logistic regression model was selected as the superior model due to its 100% accuracy and high interpretability. Combining the probabilistic output of this model with other algorithms improved all models’ accuracy to 100%. Coefficient analysis revealed that psychological variables-such as academic anxiety, suicidal thoughts, and depression-had the most negative impact, while marital status and interest in the field of study had protective effects on students’ mental health. The results of this study can be used as a powerful tool for early identification of students who need psychological support.
