Pain is commonly associated with psychological variables, such as anxiety and depression. However, only a few studies statistically analyzed the global trends and conducted a review through the bibliometric method.
This work aimed to analyze the general aspects of scientific studies worldwide on the comorbid of anxiety and pain research between 2000 and 2019.
Published papers on the comorbid of anxiety and pain from the last 2 decades were retrieved from the Web of Science core collection. To assess whether the percentage statistically decreased or increased over time by using IBM SPSS Statistics 22.0. Results: A total of 1,329 papers met the inclusion criteria. The trend of annual publications presented a significant growth from 2000 to 2019 (P<0.001) by linear regression analysis. Clinical Neurology, Neurosciences, and Anesthesiology of subject categories had superior quality and were recognized as mainstream on comorbid anxiety and pain research. The United States (416, 30.85%) and the University of Washington (23, 1.73%) were the most prolific and high-quality country and institution, respectively. Postoperative pain (11.81%) and headache (11.14%) were the hottest topic among researchers. Music, distraction, adult, dental anxiety, and preoperative anxiety were emerging hotspots and could be regarded as research frontiers.
Bibliometric analysis of the comorbidity of anxiety and pain and provides insights into research countries, institutions, authors, and core journal, visual, hot topics, overall tendency, and research frontiers that will aid in exploring hidden valuable field for future research.
