Anatomy of a Scholarly Article
Interactive example of a scholarly article by NCSU

Periodicals can include newspapers, magazines, trade journals, and scholarly journals. Each type of publication serves a purpose and audience. Generally, you will want to use scholarly journals/peer-reviewed articles for your research papers, but magazines (trade or popular) may provide inspiration or examples to illustrate a point. For instance, you might use an article from Women's Health to demonstrate the information patients are reading regarding nutrition and weight loss and how it may be misinterpreted.

Levels of Research Evidence

Levels of Evidence

Nursing research often uses a system for ranking research studies based on the strength of the evidence: quality of design, validity, and applicability to patient care. The below diagram is based on the levels of evidence described by Melnyk & Fineout-Overholt (2011).
