In order to find a relevant peer-reviewed article in CINAHL, think of the best words to describe your topic. This might be the name of a country or cultural group along with a certain disease or intervention. Add a word or short phrase to the first box, then another word in the second box. When using a phrase, be sure to put quotation marks around it so that the database knows to search for that exact phrase rather than as separate terms. Depending on the number and type of results, you might want to add additional terms your search.
Be sure to add a date range. I recommend the last five years: 2017-2022. You should also click the "peer-reviewed" button, so you find article from refereed journals.
See the attached document below for a sample search.
