Data Sources Used in the Research.com 4th Best Psychology Universities in United Kingdom Ranking
The 4th edition of the Research.com Best Psychology Universities in United Kingdom Ranking is built on a robust foundation of bibliometric data sourced primarily from OpenAlex and CrossRef, in addition to multiple other reputable data repositories. Data for the citation-based metrics that underpin the ranking were extensively collected on 27 November 2024. The central metric for institutional ranking is the cumulative D-index (Discipline H-index) of all affiliated scholars whose primary publication area is Psychology. The D-index is derived exclusively from an individual’s publications and citations within the specific discipline under examination, ensuring that inter-disciplinary factors do not skew the results.
Scope and Coverage of the Ranking
The 2024 ranking process commenced with the examination of 279,971 scientist profiles identified by aggregating data from a variety of bibliometric sources. Out of these, 38,989 researchers specializing in Psychology were subjected to detailed analysis. Inclusion criteria mandated a minimum D-index threshold of 30 for each scholar, with the majority of their prestigious publications being in Psychology. Scientist awards and their significant achievements in the field were taken into consideration as supplementary evaluation factors.
The D-index qualifying threshold for top researchers is further increased in increments of 10, depending on the aggregate number of scholars within each discipline. This flexible criterion ensures the representation of the top 1% of leading scientists for each field. To preserve the focus on subject expertise, the proximity between a scientist’s general H-index and their D-index is mandated to be 30% or less. This methodology effectively highlights domain-specific impact and commitment.
Verification and Quality Assurance Practices
Research.com recognizes that bibliometric and citation data should never be viewed as the sole benchmark for academic excellence. In pursuit of accuracy, every scientist profile included in the ranking underwent individual manual verification and cross-correlation against publications disseminated in an array of trustworthy sources. While not directly influencing a scholar’s position in the Research.com ranking, the volume of papers published in renowned journals and prominent conference proceedings is acknowledged as a valuable indicator of research significance within the discipline.
Institutional positioning in the ranking is determined by aggregating each researcher’s H-index, with data sourced from OpenAlex and CrossRef—two of the most authoritative and frequently consulted bibliometric databases in the academic community. The committee encourages all interested readers to further explore our methodology page for additional details on the data, thresholds, and verification practices employed during the ranking process.
