Objective — The aim of the study was to present the results of a citation analysis concerned with the impact of Italian researchers and institutions in psychiatry and psychology upon the international scientific community. Method — The analysis has been performed using a database of the Institute for Scientific Information (ISI). All scientific papers which were published between 1981 and 1998 in psychiatric and psychological journals included in the Science Citation Index (SCI) and the Social Sciences Citation Index (SSCI) were considered. The most cited Italian papers, authors and institutions are reported, as well the most frequently utilised journals. Results — Publications concerned with neuropsychology, psychopharmacology and biological psychiatry were the most cited. This prevalence also affected theranking of the most cited authors, even though, in this case, research groups in disciplines such as clinicalpsychology and epidemiological psychiatry appeared to be strong. The four most productive Italian Universities were characterized by the presence of both a School of Medicine and a School of Psychology. The Journal of Neurology, Neurosurgery and Psychiatry and Psychopharmacology were the most frequent vehicles of scientific communication. Conclusions — The results entail important implications for Italian research in psychology and psychiatry. On a general level, these analyses appear to be helpful for monitoring scientific production by granting agencies and for comparing different individual researchers. On a more specific level the analysis has identified the leading trends in research of Italian psychiatry and psychology.
