Background The evidence base for schema therapy has evolved significantly since it was first developed by Jeffrey Young in the 1990s. The aim of this bibliometric analysis was to summarize the trends and characteristics of the quantitative literature on schema therapy. Method PsycINFO, PubMed and CINAHL Complete databases were last searched on 1 June 2023 following the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses 2020 statement to identify peer‐reviewed journal articles written in English that reported on original quantitative research on schema therapy or schema therapy constructs. NVivo was used to complete a descriptive analysis of the bibliographic, sample and study characteristics, and a coding framework was applied to capture the aspect of the schema therapy model that was the focus of each study, as well as the study context (e.g., the population or outcomes under investigation). SciVal was used to complete citations and authorship analyses. VOSviewer was used to examine co‐authorship networks. Results A total of 704 quantitative studies on schema therapy were published by 483 unique first authors between 1994 and mid‐2023. Studies predominantly used correlational designs with small samples ( Mdn N = 153) of mostly females aged 18 years or older. The articles tended to focus on early maladaptive schemas, rather than schema domains or schema modes. Schema therapy and its concepts were most frequently studied in the context of depression and personality disorders. SciVal analyses indicated that, on average, articles were cited 27 times, with a Field Weighted Citation Impact of 1.02. Conclusions Schema therapy research output appears to have slowed in recent years and several critical research gaps were evident. Areas of high priority for future research include schema modes and coping responses, and the use of developmental and longitudinal designs to evaluate several key causal assumptions in the theory underpinning schema therapy.
