Scholarly articles are published by experts/academics in the field. In order for the articles to be published, they have to be reviewed by their peers (who are also experts in the field) to make sure all the research is correct.
Why do you need it?
Scholarly articles (peer reviewed articles) will provide the indisputable facts you'll use and are primary sources.
Use your main topics as KEYWORDS when doing research on databases. Below is an example on PTSD and TREATMENT as my keywords.
When you're searching on a database, use the filters! They are going to help narrow down your search. Remember to click on FULL TEXT and make sure the publication dates are relative to your project. The SUBJECT filter will help you narrow down your results to a specific subject.
When you're using the filters, make sure you're looking for recent publications. First limited the years to 2007- 2017. If you're having trouble, ask a librarian.
REMEMBER PEER REVIEWED = SCHOLARLY JOURNALS = ACADEMIC JOURNALS
You found an article that's perfect for you. Make sure you do a few things before you print the article out to read. Read the article's ABSTRACT. Is it what you really need? Do you understand it? Make sure it's going to give you the information you need.
Second, use the article record to find other keyword or search terms. Under SUBJECTS, there'll be a list of subjects related to your article. Try searching with a few of those terms.
Lastly, on the right hand side under the TOOLS column, there are few very useful things. You could save it to your Google Drive, you could email yourself the article, save it, or find it's permalink.
