HST 2800: Research Methods

How to find peer-reviewed articles for the literature review assignment.

What is a Literature Review?

As part of a larger work, the literature review section of an article places the author's work within the context of other studies. 

As a type of article, a review article summarizes research in a particular field of field of study.  A helpful guide to writing review articles is available at: http://www.ploscompbiol.org/article/info%3Adoi%2F10.1371%2Fjournal.pcbi.1003149

Defining your topic

Before you begin searching, try to develop a question that your research will answer.  As an example, if your chosen topic is childhood obesity, your question might be "What do studies show about school-based childhood obesity programs?" or "What does the literature say about exercise and childhood obesity?" Once you have some background information on your topic, you will find more specific questions. For example, are school-based obesity prevention programs with an internet compenent more effective than those without?

It will be easier to narrow your search if you define a specific patient population. As an example, if you are working on sucide prevention, possible populations would be "adolescents enrolled in school" or "elderly commuity residents."
