In January, APA updated our Thesaurus of Psychological Index Terms® to provide more effective searching on current topics, including sport and exercise psychology, psychological testing, mental health, and COVID-19. This update brings the total number of index terms in the Thesaurus to more than 10,000. Using the controlled vocabulary of the Thesaurus means a database search will quickly and accurately retrieve all publications related to a specific concept, regardless of the keywords the authors may have used.
