Analysis of International Research Hotspots on the Application of Chatbots in the Field of Psychological Counseling—Text Mining Based on LDA Topic Model Analysis

The application of Chatbots in the field of psychological counseling has demonstrated numerous advantages. Based on the LDA topic model, this study conducted a text mining analysis of 564 relevant papers included in the Web of Science core collection, IEEE, and ScienceDirect peer-reviewed journal collections up to 2025. The findings reveal that international research on the application of Chatbots in psychological counseling primarily focuses on four areas: artificial intelligence and mental health interventions, psychotherapy techniques and clinical practice, accessibility and integration of mental health services with technology, and specific psychological disorders and interdisciplinary applications. Future research should continue to explore the deep integration of advanced technologies with mental health services, aiming to make cost-effective, personalized, and scientific psychological counseling accessible to every individual in need.
