Science IndicatorsSM database. This database,
currently covering the period January 1997 to October 2007, surveys only
journal articles (original research reports and review articles) indexed
by Thomson Scientific. Articles are assigned to a category based on the
journals in which they were published and Thomson Scientific’s
journal-to-category field definition scheme. Both articles tabulated and
citation counts to those articles are for the period indicated.
Naturally, scientists publishing large numbers of papers have a greater
likelihood of collecting more citations than scientists publishing fewer
papers. This ranking is by total citations. For articles with multiple
authors, each author receives full, not fractional, citation credit.
Another ranking could be based on citations per paper, which reveals
weighted impact.
Essential Science Indicators lists authors ranked in the top 1% for a field
over a given period, based on total citations. It can be noted that
Biederman and Faraone were frequent co-authors on a number of highly cited
papers dealing with ADHD. Keck and McElroy were also frequent co-authors
of a number of highly cited papers concerning
schizophrenia and bipolar mania. In addition to
ADHD, schizophrenia, and bipolar disorder, depression, anxiety, and
autism were the other dominant subjects of papers by
the authors listed in the table. For the current version, 2,190 authors
are listed in the field of psychiatry and psychology, meaning that a
total of approximately 219,000 author records were reviewed to obtain
these results.
