title: [Confusing the confused: thoughts on impact factor, h(irsch) index, Q value, and other cofactors that influence the researcher's happiness].
abstract: BACKGROUND
  The need to evaluate curricula for sponsorship for research projects or professional promotion, has led to the search for tools that allow an objective valuation. However, the total number papers published, or citations of articles of a particular author, or the impact factor of the Journal where they are published are inadequate indicators for the evaluation of the quality and productivity of researchers. The h index, proposed by Hirsch, categorises the papers according to the number of citations per article. This tool appears to lack the limitations of other bibliometric tools but is less useful for non English-speaking authors.
  
  
  OBJECTIVE
  To propose and debate the usefulness of the existing bibliometric indicators and tools for the evaluation and categorization of researchers and scientific journals.
  
  
  METHODS
  Search for papers on bibliometric tools.
  
  
  RESULTS
  There are some hot spots in the debate on the national and international evaluation of researchers' productivity and quality of scientific journals. Opinions on impact factors and h index have been discussed. The positive discrimination, using the Q value, is proposed as an alternative for the evaluation of Spanish and Iberoamerican researchers.
  
  
  CONCLUSIONS
  It is very important de-mystify the importance of bibliometric indicators. The impact factor is useful for evaluating journals from the same scientific area but not for the evaluation of researchers' curricula. For the comparison of curricula from two or more researchers, we must use the h index or the proposed Q value. the latter allows positive discrimination of the task for Spanish and Iberoamerican researchers.
