Semantic analysis of keywords in foreign articles on psychotherapy (2012–2021)

Introduction. Staff of the Centre for Science and Technology Studies of Leiden University (Netherlands) were developed an analytical program VOSviewer for frequency analysis of keywords in large arrays of publications. The program is widely used in the science of science. Unfortunately, the program does not carry out meaningful analysis of terms.
The intention is to conduct a semantic analysis of keywords received using the VOSviewer program in articles on psychotherapy.
Methodology. Using the VOSviewer program, 79,6 thousand articles on psychotherapy indexed in the international database PubMed in 2012–2021 were analyzed. With 250 repetitions, 532 keywords were identified, which were routinely combined into 56 terms according to their semantic content. Results and their analysis . The combined terms allowed to distribute the array of articles into 5 clusters. In the 1st cluster the authors mainly presented the results of mental impact on patients from the standpoint of evidence-based medicine and the basic principles of health care and healthcare organization with a total link strength of 51.9 % of the total array of articles. In the 2nd cluster, mental processes were studied, including cognitive, movement disorders and memory disorders. A significant place in the study of these disorders was given to biological aspects and techniques with biofeedback, animal therapy and physiotherapy; the link strength was 15.4 %. In the 3rd cluster, emotions were analyzed that were interdependent with indicators of the quality of life of patients, stress levels, the formation of somatoform disorders, etc. As a rule, meditation and music therapy techniques were used to correct these disorders, the strength of the connection was 14.4 %. In the 4th cluster, the authors investigated social relationships, for example between professionals and patients, interpersonal relationships of patients, and mental adaptation. Optimization of these relationships was carried out using specific psychotherapeutic processes, group psychotherapy and psychoanalysis, the link strength was 13.8 %. In the 5th cluster, issues of self-control, self-esteem, self-efficacy of patients, and their attitude to a healthy lifestyle were studied. Possible behavioral disorders were corrected with the help of bodily therapy, the link strength was 4.5 %.
Conclusion. Semantic analysis revealed some similarities and differences in the clustering of articles by keywords without combining them and allowed to more objectively study the content of an array of foreign publications on psychotherapy.
