Aim — The aim of this paper is to present the results of a citation analysis concerned with the impact on the international literature of Italian researchers in psychiaty and psychology and of sub-fields, within these two disciplines, in 1995-1999 compared to 1985-1989. Method — We used a database prepared by the Institute for Scientific Information (ISI) that included all papers, with at least one Italian author, working in Italy, which appeared in two periods (1995-1999 and 1985-1989) in psychiatric or psychological journals listed in Current Contents. A citation analysis concerning the following years, up to 1999, was performed. Results — In 1995-1999 the most cited researchers were those involved in clinical psychology, psychiatry and psychopharmacology research. Neuropsychology, which dominated the period 1985-1989, underwent a clearcut decline. Conclusions — Citation analysis, concerning relatively short periods of time (five years), appears to be a very helpful tool for monitoring the development of scientific research in specific disciplines and the trend of the scientific production of researchers.
