Supplementary Data: Bibliometric Analysis of Positive Psychology (1999–2026)

This dataset provides aggregate bibliometric materials accompanying the periodization of positive psychology and its computational turn. It includes search strategies, annual publication counts, keyword frequency summaries, periodization summaries, and analysis notes. Raw Scopus and CNKI export files are not redistributed because of database licensing restrictions. Version 2 (July 2026) corrects errors identified during peer review of the companion manuscript and withdraws claims the archived files cannot support: a data-inconsistent cross-database trend statement was removed; PERMA was moved from the 1999–2010 to the 2011–2020 period; the file listing was corrected; and the thematic-evolution analysis claims were withdrawn (thematic_evolution_summary.csv is now periodization_summary.csv, labeled an interpretive summary). See CHANGELOG.pdf in the deposit for the itemized list.
