If you search the web for evaluating websites you will find a number checklists and criteria, one of which is the C.R.A.P. test. Because of how easy this acronym is to remember, I think it's worth highlighting.
C = currency
R = relevancy
A = authority
P = purpose/point of view
Some versions of this acronym include an extra A for accuracy (i.e., CRAAP). This test can be used to evaluate all kinds of information sources, not just websites. Below is a link to a printable version of this list of criteria and questions.

Identifying articles on your topic of interest is just one part of finding appropriate articles. You must also constantly assess the credibility of what you're finding. Even if you've confirmed an article is peer-reviewed, you still look at it closely. The following questions can help guide your critical assessment of the articles you find:
One other important point: When we set out to find articles on a topic, we typically have preconceived notions or hypotheses (either formal or informal) and often expect the literature to report certain findings that support our suspicion. However, it's important to keep an open mind while searching! Don't discount articles simply because they are not in line with your thinking. Evaluation of the literature needs to be "fair and balanced." :-)
