Measuring Research Impact

This guide covers some of the more popular measures of author, journal, and article impact.

Guidelines for Responsible Use of Research Metrics

What is Research Impact?

Research impact aims to describe the reach and influence of a body of work.

It can be used by individuals or groups to:

  • Strengthen a case for promotion or tenure
  • Demonstrate how grant dollars have impacted academia and society
  • Bolster grant applications 
  • Identify who is citing a body of work
  • Find collaborators

This guide covers some of the more populars measures of author, journal, and article impact. Many of these metrics are proprietary to specific companies.

Best Practices for using research metrics:

  • Metrics are not a substitute for informed, qualitative assessment.
  • Metrics should be easy to understand, transparent, and open.
  • Different contexts and disciplines may require different sets of metrics.
  • The people being evaluated should have the opportunity to verify the data.

About Journal Impact Factors

Quantitative analysis of journals is a way traditional peer review may be augmented to gain a more complete picture of a scholar's impact in his chosen field. Three measures can be used:

  • The number of publications
  • The number of times an author's publications have been cited
  • The importance of the journal where the article is published, or the Journal Ranking

Publishing traditions vary between disciplines. Because of this, it is important to compare journals within the same or similar disciplines as much as possible. This will not always be easy as more research becomes interdisciplinary but in order for these journal ranking systems to have meaning the factors measured must compare journals in similar disciplines or subject areas.

Legitimacy of Journal Rankings

Just as you may be aware of predatory journals, seeking to make money from academics eager to be published, fake impact factor sites have appeared on the web. When trying to determine where to publish try as much as possible to use well-known journal ranking resources.

A word about tenure and promotion

What "impact" do metrics have on promotion and tenure?

Those are decisions made by each department or college on campus. The best thing to do is to consult with the department chair or colleagues to learn what is useful in your discipline. You'll need a selection of tools and the set will vary by discipline.
