Nursing Research Guide: CINAHL Subject Headings

CINAHL Subject Headings

CINAHL Subject Headings - see if there are any relevant search terms for you to use.

The CINAHL Subject Headings list (controlled vocabulary or thesaurus) includes 16,000+ terms. In many cases, the most efficient way to search CINAHL is to use these headings that have been assigned to related articles by the CINAHL indexers. Not all concepts have a CINAHL heading assigned to them. You will see these called Subjects, Subject: Major Heading, Major Subjects, and Minor Subjects in the results and narrowing features.

A definition from Ebsco: These Headings follow the structure of the Medical Subject Headings, or MeSH, used in PubMed by the National Library of Medicine. This structure has been used to develop the CINAHL subject headings which reflect the terminology used by nursing and allied health professionals.

For more information see:

  • Using the CINAHL/MeSH Headings Feature. This 3 minute and 33 seconds flash video tutorial, from the Ebsco company that owns CINAHL. This is a useful illustration of how to search for CINAHL Headings. The Search History feature advice is good too.

Searching with "or" will provide you with more results, but will provide results with articles that may contain only one of the CINAHL Headings you selected. More information about searching with "and" or "or" in CINAHL is located online at the Brainstorming a Search page.
