Worldwide research productivity in the field of psychiatry

Abstract

BackgroundThe field of psychiatry has seen significant progress in recent years due to worldwide contributions. National productivity, however, in the field of psychiatry is still unclear. In our study, we investigated contributions of individual nations to the field of psychiatry.MethodsThe Web of Science was used to perform a search from 2011 to 2015 on the subject category “psychiatry”. The total number of articles, citations and the per capita numbers were obtained to analyze the contributions of different countries.ResultsIn psychiatry journals from 2011 to 2015, 84,760 articles were published worldwide. The most productive world areas were North America, East Asia, Europe and Oceania. The percentage of articles published in high-income countries was 87.77%, middle-income countries published 12.07%, and lower-income published 0.16%. Most articles were published by the United States (32.68%); the United Kingdom was next (8.59%), which was followed by Germany (6.77%), Australia (5.87%), and Canada (4.9%). The country with the highest number of citations (243,394) was the United States. A positive correlation was found between the population/GDP and the number of publications (P < 0.01). Australia ranked the highest when normalized to population size, and the Netherlands and Norway were next. The Netherlands ranked highest, followed by Israel and Australia when adjusted for GDP.ConclusionsThe authorship of most of the psychiatry articles was from high-income countries and few papers came from low-income countries. The most productive country was the United States. However, when normalized to population size and GDP, some European and Oceania countries were most productive.Electronic supplementary materialThe online version of this article (doi:10.1186/s13033-017-0127-5) contains supplementary material, which is available to authorized users.

Investigating global trends in paraquat intoxication research from 1962 to 2015 using bibliometric analysis

“…These results match those observed in earlier bibliometric studies, These findings were expected because the USA has been recognized for its various and high‐quality international journals, scientists, and institutions in different fields of science . Other possible explanations for this, as suggested by previous studies, are that research outputs are positively correlated with a country's rapid economic development, population size, medical infrastructure, or academic investment. Furthermore, paraquat was still responsible for most cases of all pesticide deaths reported cases in the American Association of Poison Control Centers in 2009 …”

Nursing Research Literature Production in Terms of the Scope of Country and Health Determinants: A Bibliometric Study

“…It seems that smaller countries, especially Scandinavian ones, tend to be more productive per capita, while larger countries are more productive in the total number of published papers. A similar phenomenon was observed in research literature production in psychiatry (Zhang et al, ) and paracetamol poisoning (Zyoud, Al‐Jabi, & Sweileh, ). It is interesting to note that, among the 20 most productive countries, only 5 are G8 countries.…”

“…Similar results were found for dental research, for which, in addition, political stability was a significant factor influencing research literature production (Allareddy et al, ). A positive correlation between GDP and number of papers was also found in psychiatry (Zhang et al, ), paracetamol poisoning (Zyoud et al, ), arthroscopy (Liang et al, ), and endocrinology (Zhao et al, ). Indeed, it is known that developing countries, due to lack of resources, inadequate representation in journal editors' boards, and lack of international collaboration, contribute less to research literature production than developed countries (Chu, Jayaraman, Kyamanywa, & Ntakiyiruta, ; Langer, Díaz‐Olavarrieta, Berdichevsky, & Villar, ; Sooryamoorthy, ).…”

Global scientific trends on aflatoxin research during 1998–2017: a bibliometric and visualized study

“…Bibliometrics and evaluation of research performance have been carried out on a wide range of health topics [7][8][9][10][11][12][13][14][15], and several have been carried out in the fields of environmental studies [16,17], and toxicology [18][19][20][21][22][23][24]. Yet, to the best of my knowledge, only a few bibliometric studies in food contamination have been done recently [25][26][27][28], and only one bibliometric study explicitly focused on aflatoxin has been published by using Web of Science (WoS) database for data collection [28].…”
