INTRODUCTION Scientific collaboration is vital for to the advance of knowledge and is especially important in health sciences. The aim of this study is to identify scientific collaboration indicators and co-authorship networks of researchers and Spanish institutions that publish on multiple sclerosis (MS) during the period 1996-2010.
MATERIALS AND METHODS The analyzed papers were obtained from Web of Science and Scopus international databases, and IBECS and IME national databases, applying specific search profiles in each one of them. In order to identify collaboration networks all signed papers were quantified and co-authored measures were obtained, as the different indexes, degree, intermediation and closeness.
RESULTS 1,613 articles were published in the period 1996-2010, 92% of them in collaboration. With 10 or more works signed in collaboration, 20 Spanish research groups in MS were identified. 64.23% of the papers were published in collaboration between Spanish institutions, and 33.85% were in collaboration with foreign institutions. The institutional participation analysis has identified a large network of institutional partnerships that integrates 27 institutions, with the Hospital Vall d’Hebron in a central position. International collaboration is headed by the U.S. and European countries, most notably the UK and Italy. CONCLUSION. The most collaborative authors, institutions, and work groups in Spanish research in MS have been identified. Despite these indicators that characterize the collaboration in this area, it is necessary to enhance cooperation between them, since this collaboration is positively related to the quality and impact of research and publications.
