The data above were extracted from the Essential Science Indicators database of Thomson Reuters. This database, currently covering the period January 2000 to February 2010, surveys only journal articles (original research reports and review articles) indexed by Thomson Reuters. Articles are assigned to a category based on the journals in which they were published and the Thomson Reuters journal-to-category field-definition scheme. Individual papers published in influential multidisciplinary journals such as Nature and Science are assigned to their appropriate fields. Both articles tabulated and citation counts are for the period indicated. Naturally, institutions publishing large numbers of papers have a greater likelihood of collecting more citations.

This ranking is by citations per paper (impact) for European institutions that published 1,000 or more papers in psychiatry and psychology during the period. For papers with multiple institutional addresses, each institution receives full, not fractional, citation credit. Essential Science Indicators lists institutions ranked in the top 1 per cent for a field over a given period, based on total citations. For the current version, 375 institutions are listed, meaning that a total of 37,500 institutions were surveyed to obtain these results.

Of the 375, 76 institutions published 1,000 or more papers. The ranking by citation impact seeks to reveal heavy hitters based on per-paper influence, not mere output or total citations. Also appearing is the world rank by impact for each of the institutions.
