Most scholarly journals indexed by our databases including PubMed are peer-reviewed, but peer review criteria and reviewer qualifications vary. Always check a journal's editorial information or ask the publisher about policy for specific journal titles.
If you are using a database such as CINAHL that does include non peer-reviewed information, there will be a peer-reviewed filter that you can check in order to refine your search to include only those articles.
We do have an excellent resource that will give you more information on how to find peer-reviewed articles and journals. It can be found in our Peer Review and Scholarly Articles guide.
