    To quantify by means of bibliometric indicators the scientific productivity of Spanish researchers and institutions that publish on multiple sclerosis in national and international journals during the period 1996-2010, and to determine their impact. Papers under study were obtained from Web of Science and Scopus international databases, as well as IBECS and IME national databases, applying specific search profiles in each. 1613 articles were published in 460 journals, of which 71 were Spanish and 389 non Spanish, being the most productive Revista de Neurologia (n = 204), Multiple Sclerosis (n = 102) and Neurology (n = 97). The articles have been published mostly in English (71.92%) and Spanish (27.40%), participating 4728 authors from 1224 different institutions. The 67.08% of the papers have been cited at least once, but 32.92% have not received citations. The mean number of citations per paper was 12.47 ± 28.42. The most cited journals have been Neurology (n = 1821), followed by M...

    Concern for encouraging gender equality makes it one of the high priority spheres of action for governments and organisations responsible for instigating scientific policies, with particular importance being placed on including the gender variable in evaluative analyses of scientific and technological activity. A comparative study was made, broken down by gender, of the scientific output of Spanish researchers with a high production in the field of substance abuse. We identified the gender of 338 authors who had published more than four different articles during the period from 1999-2004 and which were indexed in the IME/Indice Médico Español and the SCI/Science Citation Index databases, making a comparative analysis of their output and collaboration patterns, based on the gender variable. In the area of substance abuse, of those with the highest output (> 9 papers), 70% were men compared with 30% women. Among the average producers (5-9 papers), 57% of the authors identified were...

    There is growing concern for promoting equality between sexes and full integration of women in research activities. The purpose of this study is to identify the bibliometric characteristics of articles published during the 2001-2005 period in Enfermedades Infecciosas y Microbiología Clínica (EIMC) from the perspective of gender. EIMC records for 2001-2005 were obtained from the Science Citation Index database and differences according to sex were calculated for the following indicators: year of publication, type of document, number and order of author signatures, number of collaborators, and the signature/article index at the institutional and geographical level. A total of 2,163 authors were identified, 1,220 (56.4%) men and 943 (43.6%) women. The greatest of contribution from women was in original articles (42.32% of signatures). Excluding the Centro Nacional de Microbiología (Spanish National Center for Microbiology), the participation of women was lower than men in the most prod...

    This paper examines the influence of the loss of reference points for the digital readout in user interaction. This has been done using 5 eBooks from different disciplines, accessed through various consultation platforms. We have examined different aspects of the information architecture of these sites to find out if users are aware of their location in the text during reading and maintaining control to scroll through it. The results indicate the need to design more robust information architectures to overcome the problems of loss of location and convert the digital reading experience into a viable alternative

    This is a cross-sectional study in which we compared the perceived quality of life (QoL) of patients receiving outpatient treatment for cocaine (n = 727) and heroin dependence (n = 469), by analyzing differences by gender and time in treatment. Participants were recruited from addictive behavior centers in Spain in 2004. The World Health Organization Quality of Life Assessment Instrument (WHOQOL-Bref) was used as a measure. Analysis of covariance and multivariate linear regression were used. This study shows the relevance of considering the role of gender in QoL studies, and the need to evaluate the effectiveness of treatment in the improvement of QoL. Limitations of the study were noted.

    The aim of this paper is to present the bibliometric indicators for Revista Española de Cardiologíathat were obtained from the "Potential impact factor of Spanish medical journals in 2001" study financed by the Spanish Ministerio de Educacion, Cultura y Deporte. Citations to Revista Española de Cardiología, its national and international impact factor, and its immediacy index were calculated with methods similar to those used by the Institute for Scientific Information. National indicators were based only on citations from 87 Spanish journals considered source journals, whereas international indicators were calculated on the basis of citations from both national journals and foreign source journals in the Science Citation Index. Revista Española de Cardiologíaobtained a national impact factor of 0.719 and an international impact factor of 0.837, placing it at the head of the ranking of Spanish medical journals.

    Twenty years of Spanish psychological research in Psicothema (1989-2008). Scientific collaboration and gender equality are two spheres of great interest for the organizations responsible for instigating scientific policies. We have identified the research groups and women's contribution to one of the most outstanding Spanish psychology journals. We have selected papers published during the 1989-2008 period in Psicothema. A bibliometric and network analysis was carried out using the Pajek Software tool. We have analysed 1,718 papers, written by 2,423 authors, 53.45% men and 47.54% women. We have identified 86 research groups made up of 293 researchers. We have observed a high increase of productivity and collaboration in the 1999-2008 period, as well as the consolidation, growth, and evolution of many incipient groups identified in the 1989-1998 period, benefiting from the increased interest and prestige of the journal. Despite the increase in the number of women, rising from 35....

    The publication of research articles has increased considerably in recent years in all biomedical fields. The present study examines the position of Spanish quality research in cardiology in the European and world context, and its evolution during the 5-year period 2003-2007. Using the Science Citation Index Expanded of Thomson Reuters as data source, we compared Spanish cardiovascular scientific production with that of the rest of countries in the European Union and of the most important countries worldwide, along with relative productivity as per number of inhabitants and Gross Domestic Product, and the number of citations in the journals of the <Cardiac and Cardiovascular Systems> area of the Journal Citation Reports (CCS-JCR). Spain ranks sixth in the European Union and ninth worldwide in scientific production (tenth worldwide if only the journals of the first quartile of the CCS-JCR area are considered). As regards the number of citations received, Spain ranks seventh in the European Union and eleventh worldwide. In terms of relative productivity as per number of inhabitants and Gross Domestic Product, the Spanish ranking is less favorable (positions 15 and 18, respectively). The ranking of Spanish cardiovascular research is similar to that of other biomedical fields, though its position is less favorable in relation to certain demographic and economical indicators. In order to maintain adequate investigational levels, it is necessary for the European governments and scientific societies to regard the promotion of high-quality cardiological research as a priority concern.

    The Injection Drug User Quality of life Scale (IDUQOL) measures the unique and individual circumstances that determine the quality of life of injection drug users. This paper reports the psychometric properties of the Spanish version, for drug dependent persons with or without injectable consumption using a revised instrument: Drug user Quality of Life Scale-Spanish (DUQOL-Spanish). We studied 169 outpatients in 9 Spanish drug treatment centers. Factor analysis, internal consistency, test-retest reliability and criterion-related validity were assessed. The results show the essential unidimensionality of the scale, which supports the use of a total score. Both internal consistency (Cronbach's alpha: 0.86), and test-retest reliability (r=0.79) of the total score were high. Criterion-related validity supports the interpretation of the DUQOL-Spanish total score as measuring a construct consistent with quality of life. This study suggests that the DUQOL-Spanish is a valid instrument to measure subjective quality of life in Spanish drug users, and allows the identification of life areas that are considered by the patient important to change in order to improve their quality of life.

    Driving under the influence of alcohol and drugs has been identified as a risk factor for road traffic crashes. We have assessed the prevalence and predictor factors for driving after alcohol and drug use by adolescents.A cross-sectional survey involving 11,239 students aged 14–18 years from 252 private and public schools in the Valencia region of Spain was conducted. The prevalence and predictors of driving after alcohol use, alcohol and drug use, or drug use during the previous 6 months were measured.Of the students who reported driving (20%), 45.1% indicated driving after alcohol and drug use. The consumption of various drugs was higher among students who drove a vehicle compared with those who did not. The likelihood of driving after consuming alcohol, or alcohol and drugs, increased in line with the number of standard drink units per week, reports of any lifetime alcohol- or drug-related problems, and poor family relationship. In addition, masculine gender and early alcohol use increased the likelihood of driving after consuming alcohol.Driving after alcohol and drug use is quite prevalent among adolescents in the Valencia region of Spain. There is a need for implementation of targeted policies for adolescents. This should focus on education and information on alcohol/drug use and driving.
