Abstract: Background: Our purpose was to examine the use of classification 
and diagnostic systems in the field of psychiatry ( CDSP) from a 
bibliometric perspective, over the period 1980-2005. Methods: We selected 
( in EMBASE and MEDLINE databases) documents that contained, in any of 
their sections, the descriptors 'psychiatr*', 'DSM*', 'ICD*', 
or 'diagnostic criteria', as well as other more specific descriptors. As a 
bibliometric indicator of production we applied Price's law. We also 
calculated the national participation index ( PI) and correlated it with 
overall PI in biomedical and health sciences, and with PI in the 
discipline of psychiatry. Results: We obtained 20,564 original documents; 
15,743 referred to the Diagnostic and Statistical Manual of Mental 
Disorders ( DSM) and 3,106 to the International Classification of Diseases 
( ICD). Our results indicate non-fulfilment of Price's law, since 
scientific production on CDSP does not undergo exponential growth ( 
correlation coefficient r = 0.9651, vs. r = 0.9927 after linear 
adjustment). Of the 10 journals with the highest impact factor in the 
field of psychiatry, the Journal of Clinical Psychiatry has the highest PI 
in the DSM subgroup ( PI = 14.77), and the British Journal of Psychiatry 
in the ICD subgroup ( PI = 1.54). The principal producer country is the 
United States ( PI = 37.9), though in proportion to its production in the 
psychiatric field the ranking is headed by Finland. Only 10 countries, of 
the 20 major producers in health sciences, surpass their own PI in the 
field of psychiatry ( Brazil, Italy, Japan, Austria, Spain, Germany, 
France, India, Switzerland, and China). Conclusions: Over recent years, 
the use of CDSP ( basically the DSM or ICD) in the scientific literature 
has increased. Nevertheless, the abstracts to these studies, included in 
the principal databases, should always specify the diagnostic criteria 
employed, with a view to increasing information levels and reliability for 
the reader. Copyright (C) 2008 S. Karger AG, Basel.
