There are two major types of periodical: scholarly or popular.
Popular periodicals are the kind you would buy to read for fun. They may have some value for research, depending on the topic, but they are usually not the preferred type of resource for research papers.
Scholarly periodicals are written for and by people who work in academics: professors, researchers, undergraduate or graduate students. This type of article is best suited for your research because it is reliable and authoritative.

Some of the library's online databases, such as Academic Search Complete and others have a feature that allows you to click in a checkmark box to find articles from peer-reviewed journals. This should weed out articles from magazines, newspapers, and non-peer-reviewed journals.
NOTE: Not everything published in a peer reviewed journal is a peer reviewed article. Peer reviewed journals typically include letters to the editor, commentaries or book reviews. These are not considered peer reviewed articles. Look carefully at the articles in your list of results to make sure they have the criteria for a scholarly article.
If you have a journal and you need to check if it is peer reviewed, use the Ulrich's Periodical Directory database.
Enter the name of the journal in the search bar, then look for the little referee's jersey icon or the line that says "Refereed: Yes." "Refereed" is just another way of saying "peer reviewed," so if you see either or both of those things, your journal is peer reviewed.
If you don't see the icon or if the description of the journal says "Refereed: No," that journal is not peer reviewed.
