Abstract: Objective To introduce co-word analysis into the current situation studies on children′s tic disorder (TD), to analyze and compare the similarities and differences between domestic and foreign research directions over the past five years, and to find out the advantage and weakness of Chinese research status in this field. Methods The keywords were determined as “Tic Disorder” AND “child*”.Research papers that meet the research standards related to children with TD published from January 2015 to December 2019 were searched and screened in Pubmed, CNKI, VIP and Wanfang Databases.High frequency keywords were counted, and cluster analysis was conducted on them with SPSS 20.0.Co-occurrence analysis was conducted by using Ucinet 6.0 and Netdraw, and the co-occurrence relationship between high-frequency keywords was visualized. Results A total of 300 research articles related to children with TD were retrieved, including 206 in China and 94 in foreign countries.The co-occurrence analysis of high-frequency keywords in children′s TD research papers at home and abroad was conducted.The hot keywords in domestic literature included clinical efficacy, aripiprazole, risk factors, TCM therapy, etc and that in foreign literature included comorbidities, therapeutic efficacy, epidemiology, etc.The research direction of foreign countries was more novel and richer than domestic ones, which included more comorbidity, epidemiology and research methods than domestic research, and the keywords are more accurate and standardized.Domestic research was more concerned with research on drug efficacy and Chinese medicine treatment. Conclusions The overall research direction of children′s TD in China and abroad is basically similar.The foreign literature network diagram is more complicated, and the keywords are more standardized and accurate.The research and development of children′s tic disorder in China is in a good trend, and more researches are warranted in future in terms of comorbidities, epidemiology and research methods.
