Mental Stress Prediction Dataset from Bangladesh with PSS-14 Scores and Demographic, Behavioral, and Psychological Features

This dataset contains survey-based demographic, lifestyle, academic/work-related, health, and social variables collected from participants in Bangladesh for mental stress analysis using machine learning. Stress labels were derived from Perceived Stress Scale (PSS-14) responses. The original PSS items were removed from the final released dataset to prevent data leakage. The dataset can be used for multiclass mental stress prediction, classification benchmarking, and explainable machine learning research.
