Data Sources and Bibliometric Collection
The 5th edition of the Research.com Best Psychology Scientists in Egypt Ranking is grounded on a comprehensive assembly of bibliometric data primarily sourced from OpenAlex and CrossRef, alongside multiple other reputable data repositories. The citation-based metrics that inform this ranking were meticulously collected on January 12, 2026. This extensive dataset ensures an up-to-date and thorough evaluation of scholarly impact. A researcher's rank within this listing is determined by their D-index (Discipline H-index), a specialized metric that exclusively accounts for publications and citation metrics pertinent to the discipline under consideration, thereby providing a focused assessment of their contributions to Psychology.
Scope of Research and Qualification Criteria
The ranking process involved the examination of 279,971 scientist profiles compiled from a diverse range of bibliometric data sources, encompassing all academic disciplines. Within the scope of Psychology specifically, 1,043 scientists were identified and rigorously evaluated. To qualify for inclusion, each scientist was required to possess a D-index of at least 30, with a majority of their tier publications demonstrably situated within the field of Psychology. Furthermore, notable awards and achievements specific to Psychology were also factored into the assessment.
The threshold for the D-index is dynamically adjusted in increments of 10 relative to the total estimated number of scholars within each discipline. This adaptive scaling guarantees representation of the top 1% of leading researchers. Additionally, to ensure disciplinary focus and consistency, candidates typically exhibit a maximum 30% discrepancy between their general H-index and their D-index.
Additional Verification Practices
Recognizing that raw bibliometric data alone can never serve as an absolute measure of a scholar’s scientific output, the research team conducted thorough manual verification of all scientist profiles. Each profile was cross-correlated against publications indexed by a broad spectrum of trustworthy sources to substantiate accuracy and relevance.
Although not directly influencing a researcher’s ranking position, the volume of papers published in high-impact journals and prominent conference proceedings remains a significant secondary indicator of scholarly contribution within Psychology.
Ultimately, ranking positions are established relying on each researcher’s D-index as derived from OpenAlex and CrossRef—the leading bibliometric databases widely acknowledged for their robustness and transparency.
