[Co-authorship and collaboration networks in Spanish research into multiple sclerosis (1996-2010)].

Abstract：

: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. TITLE:Coautoria y redes de colaboracion en la investigacion española sobre esclerosis multiple (1996-2010). :Introduccion. La colaboracion cientifica es fundamental para el avance del conocimiento y es especialmente importante en ciencias de la salud. El objetivo de este trabajo es identificar los indicadores de colaboracion cientifica y las redes de coautoria de los investigadores e instituciones españolas que publican sobre esclerosis multiple (EM) durante el periodo 1996-2010. Materiales y metodos. Los trabajos objeto de estudio se han obtenido de las bases de datos internacionales Web of Science y Scopus, y nacionales IME e IBECS, aplicando perfiles de busqueda especificos en cada una de ellas. Se cuantificaron todos los trabajos firmados en coautoria y se obtuvieron como medidas del analisis estructural el grado, indice de intermediacion e indice de cercania. Resultados. Durante el periodo 1996-2010 se publicaron 1.613 articulos, de los que el 92% se realizo en colaboracion. Aplicando un umbral de 10 o mas trabajos firmados en colaboracion, se han identificado 20 grupos de investigacion españoles en EM. La mayor parte de los trabajos (64,23%) se ha publicado en colaboracion entre instituciones españolas, y el 33,85%, en colaboracion con extranjeras. El analisis de la participacion institucional ha permitido identificar un gran nucleo o red de relaciones de colaboracion institucional que integra 27 instituciones, en la que ocupa un lugar central el Hospital Vall d'Hebron. La colaboracion internacional esta encabezada por Estados Unidos y paises europeos como Reino Unido e Italia. Conclusion. A pesar de la bonanza de los indicadores de colaboracion que los caracterizan, es necesario potenciar la colaboracion entre autores, instituciones y grupos de trabajo, ya que esta se relaciona positivamente con la calidad e impacto de la investigacion y de las publicaciones medidos a traves de las citas.
