Look for Methodology filters and facets

• PsycINFO has a Methodology limit. You can select "empirical study" or specific types of studies, including qualitative or quantitative studies.
• PubMed's Article Type limit includes various types of empirical research.

When there's not a way to limit by methodology:

1. Look through the results and scan the abstract for clues to recognize it's empirical.
2. Try searching with words that describe types of empirical studies (list not exhaustive):
   empirical OR qualitative OR quantitative OR "action research" OR "case study" OR "controlled trial" OR "focus group"
3. Enter other terms you'd expect to see in an abstract. Some suggestions:
   findings OR participant* OR investigat*

The Empirical Articles/Studies online guide can help you learn to recognize empirical articles and has a video showing PsycINFO's Methodology limit.
