Publications on the association between cognitive function and pain from 2000 to 2018: A bibliometric analysis using Citespace

Background: This study aimed to use CiteSpace software to conduct a bibliometric analysis of published studies on the association between pain and cognitive function from 2000 to 2018. The study also aimed to determine publication patterns and authorship and to identify recent trends for research in this field. Material/Methods: Publications on the association between cognitive function and pain between 2000 and 2018 were identified from the Web of Science database. Bibliographic information, including authorship, country, citation frequency, changes in citation, and interactive visualization were generated using CiteSpace software. Co-citation, or frequency of two publications cited together by another publication, was also studied. Results: On 8th January 2019, 4,889 publications were identified. The United States (1132 publications) and the University of Washington (87 publications) were the most productive country and institution, respectively. The journal, Pain (182 publications) had the largest number of publications and was the most frequently cited journal (citation counts, 1569) with the highest centrality (0.62). Author A had the largest number of publications (21). Author B had the greatest co-citation count (223). Author C tied with Author D as the first co-cited author in terms of centrality (0.18). Author E in 2011 (co-citation count, 96) and Author F in 2008 (centrality: 0.11) had the highest co-citation counts and centrality, respectively. The keyword ‘empathy’ ranked first for research developments with the highest citation burst (10.045). Conclusions: Bibliometric analysis of the association between pain and cognitive function might identify new directions for future research.
