Research Impact is the influence of a scholar's work on academia as well as the wider world.

  • Academic Impact: Contribution to academic advances, across disciplines, including advances in understanding, methods, theory and application
  • Societal Impact: Benefits to individuals, communities and nations by enhancing quality of life, health, and improving the effectiveness of public services and policies
  • Economic Impact: Promoting national and global economic competitiveness

Adapted from "Pathways to Impact" Research Councils UK.

Why is it Important?

Research Impact can help support:

  • Application for promotion or tenure
  • Grant proposals or renewals
  • Ensuring that your work is properly credited
  • Connecting to other researchers engaged in related research across disciplines

Key Definitions

The journal impact factor measures the frequency with which an 'average article'  in a journal has been cited in a particular year or time period.

The h-index measures an author's productivity (number of publications) and citation impact (number of citations received).

The g-index is an index for quantifying scientific productivity based on publication record (an author-level metric). It was suggested in 2006 by Leo Egghe.  See Harzig's Publish or Perish Manual.

The i10-index is a measure used only be Google Scholar that shows the number of publications with at least 10 citations.

The Eigenfactor score ranks a journal's influence or prestige by looking at the number of times articles published in a journal over the past 5 years have been cited in the Journal Citation Reports (JCR).  Citations from more influential journals are weighted more than citations from less influential journals.

Altmetrics are non-traditional measures of citation impact.  They are based on online activity from many web services such as: PubMed, Mendeley, Facebook, Twitter, research blogs and other sources.  They show how often an article has been viewed, downloaded or shared via various social media outlets.
