If you already have already found the journal article, you can check if it comes from a peer reviewed journal by checking in Ulrich’s International Periodical Directory. Access Ulrich's by clicking on the Databases and electronic resources tab and select U in the databases by title list.
Once the database is open, type in the name of the journal you found the article in (eg: Women and Health). There will be a small symbol that looks like a soccer umpire's shirt (black and white striped) on the left hand side if that journal is peer reviewed.
If you only want to search for articles that are peer reviewed, some databases will allow you to limit your search by 'peer review. For example, in CINAHL you can type in your keywords then scroll down to the 'Limit your Results' section and tick 'peer reviewed'.
Other databases that let you limit your search results to peer-reviewed journals are: CrossSearch ( after you have got your search results check the box beside "Limit to articles from peer-reviewed publications" under the Refine your Search heading at the top), any database on the EbscoHost platform, Proquest Central and most other Proquest databases.
