Qualitative & Quantitative Studies in CINAHL


Check the Research check box, and use the Clinical Queries menu on the Advanced Search:

  • Qualitative-High Sensitivity for a broad search
  • Qualitative-High Specificity for a narrow, specific search
  • Qualitative-Best Balance for something in between



There is no easy way to specify quantitative studies in CINAHL.

Randomized Controlled Trials (check box or in the Publication Type menu) are often quantitative, or at least have a quantitative aspect.

With the Research check box, use the Publication Type menu:

  • Equations and Formulas
  • Statistics
  • Tables and Charts
  • Randomized Controlled Trials (if you haven't already done a search with the check box, see above)
    (you can select more than one option in the drop down box by using CTRL-click (Windows) or Command-click (Mac))

Graph and Chart are available from the more limited Image Quick View check boxes (bottom of the Limits menu), as well. Results will be mostly 1-click full text, unlike the Publication Type menu options above.

These don't guarantee quantitative studies, but they help narrow things down.

Adding other types of research

You can combine these searches with other research-related options, such as the Age Groups, or Human/Animal studies options, or keywords related to types of studies, like 'phenomenology'.
