What is a Peer Reviewed Article?
Peer review is a process that many, but not all, journals use. Article manuscripts submitted to peer-reviewed journals are not automatically accepted and published.
In peer review, a panel of experts in the given field review the manuscript to determine aspects such as the quality of research, appropriateness for the journal, and relevance to the field. One of three decisions is made: accept, reject, or revise based on commentary from reviewers.
The process of peer review is thought to help ensure that high quality articles appear in journals.
Another term for peer-reviewed is refereed. Peer-reviewed journals may also be called scholarly.
Remember that magazines, Internet sources, and books are not the same as peer-reviewed journals.
In psychology, articles that report on original/new research studies may be referred to as primary sources or empirical.
Articles that either interpret or analyze empirical articles are considered review articles. Such articles are often referred to as secondary sources or secondary research.
You can't just throw your thesis into a database-they cannot parse whole sentences properly.

Look at your results, what terms are popping up? You might not have phrased it like that, but maybe that is what it is called in the literature.
If there's a thesaurus tool available, use it! PsycINFO's thesaurus tool is invaluable! Also be sure to look at an article's subject terms or author supplied keywords.
