Music-based emotion regulation: a bibliometric systematic review (2000-2024).

Background: Music Emotion Regulation (MER) research has emerged as a significant field in mental health intervention, yet a comprehensive bibliometric analysis of its development and current status is lacking. Purpose: This research aims to systematically analyze the knowledge structure, research trends, and development patterns in MER research through bibliometric analysis. Methods: Using data from the Web of Science Core Collection (2000-2024), we conducted a comprehensive bibliometric analysis using R for primary analyses. We examined publication trends, collaboration networks, research themes, and emerging directions through multiple bibliometric indicators including co-citation analysis, keyword co-occurrence, and research theme evolution. Results: The analysis revealed three distinct development phases of MER research: initial exploration (2000-2009), rapid growth (2010-2019), and maturation (2020-2024). Research in the field demonstrates a clear transition from theoretical foundations to practical applications, with increasing methodological sophistication and cross-disciplinary integration. International collaboration networks show a "tri-polar" pattern centered in East Asia, Europe, and North America, with distinctive regional research characteristics. Conclusion: MER research has evolved into a mature, interdisciplinary field with robust theoretical foundations and practical applications. Future development trends point toward increased integration of artificial intelligence, personalized intervention strategies, and expanded international collaboration.
