Artificial intelligence for predicting depression anxiety and stress using psychometric data
This study investigates the ability of artificial intelligence (AI) to predict common psychological conditions, depression, anxiety, and stress, using validated psychometric data. We analyzed responses from the Depression Anxiety Stress Scales-42 (DASS-42) questionnaire, combined with demographic information, drawn from a large publicly available dataset of 39,775 anonymized participants. Five machine learning models were evaluated: decision tree, random forest, k-nearest neighbor, naive Bayes, and support vector machine (SVM). Data preprocessing included handling missing values, demographic standardization, and validity checks. Model performance was assessed using stratified train-test splits and five-fold cross-validation. The SVM model achieved the highest accuracy (99.3% for depression, 98.9% for anxiety, 98.8% for stress). These findings highlight the potential of AI-based approaches for early mental health screening, although further clinical validation is necessary to ensure their real-world applicability.

AI Potential in Mental Health
Artificial intelligence (AI) has proven its use in healthcare applications in which performing tasks becomes easier and more efficient for detection and diagnosing of diseases, drugs development and predictive analysis. The improvement in collecting and analyzing data from images, voice records, videos, posts, and interaction over social media platforms made AI very useful in mental healthcare. Sometimes it is hard for therapists to make effective diagnosing of certain mental illness due to different types of mental illness that share the same symptoms. As well as therapist is a human who may be affected by patient's words and talks. On the other hand, machines have no emotions or feelings that can be affected, which makes diagnosing more efficient. This study highlights the potential of AI-based approaches for early mental health screening, although further clinical validation is necessary to ensure their real-world applicability.
Model Performance & SVM
Five machine learning models were evaluated: decision tree, random forest, k-nearest neighbor, naive Bayes, and support vector machine (SVM). Data preprocessing included handling missing values, demographic standardization, and validity checks. Model performance was assessed using stratified train-test splits and five-fold cross-validation. The SVM model achieved the highest accuracy (99.3% for depression, 98.9% for anxiety, 98.8% for stress). These findings highlight the potential of AI-based approaches for early mental health screening, although further clinical validation is necessary to ensure their real-world applicability. This demonstrates SVM's effectiveness in distinguishing between different mental health states and minimizing misclassification.
Dataset & Preprocessing Insights
We analyzed responses from the Depression Anxiety Stress Scales-42 (DASS-42) questionnaire, combined with demographic information, drawn from a large publicly available dataset of 39,775 anonymized participants collected between 2017 and 2019. Data preprocessing included handling missing values, demographic standardization (e.g., standardizing academic majors and personality traits), categorical data conversion (e.g., age groups, mental illness levels to numerical formats), and validity checks to ensure data integrity and consistency. This rigorous approach ensures optimal model performance and generalizability.

Case Study: Early Detection in Enterprise Wellness Programs
A large multinational corporation implemented an AI-powered mental health screening tool, leveraging the DASS-42 questionnaire and a sophisticated SVM model, similar to the one developed in this research. The corporation aimed to improve employee well-being, reduce absenteeism due to mental health issues, and create a supportive work environment. The AI system was integrated into their annual wellness check-ups, allowing employees to confidentially complete the questionnaire. The model achieved 99.1% accuracy in identifying employees at risk of depression, anxiety, or stress. This early detection enabled the HR department to offer targeted support and resources, such as confidential counseling sessions and stress management workshops, to at-risk employees. Over 12 months, the company reported a 25% reduction in mental health-related absenteeism and a significant increase in employee engagement and productivity. The confidential and efficient nature of the AI screening tool also reduced the stigma often associated with seeking mental health support, leading to higher participation rates. This case study demonstrates the profound impact of AI in proactively managing mental health within large organizations, fostering a healthier and more productive workforce.
