Literature Searching for Animal Testing Alternatives

Step 1: Define the Question

Formulating the Question

It may help to think of your research question in four parts. Leenaars, et al suggest four components for a focused research question in the field of animal research.

   1.) Intervention/Exposure

   2.) Disease of interest/health problem

   3.) Animal/animal species/population

   4.) Outcome measures

A research question including these concepts could be formatted as "What is the effect of [intervention/exposure] on [outcome measures] in [animal species/population] for [disease/health problem]?"

Brainstorming Keywords

It may be useful to first determine what keywords specific to your research protocol are necessary, and then to add keywords for the reduction, refinement, or replacement of animal research subjects (the "Three R's").

   Tips for Research-Specific Keywords

  • Scientific and common names of any species being studied
  • Scientific and common names of any diseases or conditions being studied
  • Generic name, trade names, and CAS RN of drugs and/or chemicals being used
  • Treatments being used
  • Scientific and common terms for tissues, systems, or cell lines being studied

   Tips for "Three R's" Keywords

There are many options for keywords in the "3R's". The Health Sciences Library at the University of North Carolina at Chapel Hill has compiled a list of suggested keywords that is replicated in this guide. In addition, you may wish to use the sample MeSH keywords and searches when constructing a PubMed MEDLINE or OVID MEDLINE search or consult the National Agricultural Library's Thesaurus for Animal Use Alternatives when searching AGRICOLA or for ideas for keywords to use in other databases.
