Types of Scholarly Articles

Sometimes a professor might ask you to find original research or may ask you to not use literature reviews/systematic reviews as sources, but what do those terms mean? How can we tell if our potential source meets our professor's criteria?

Research Articles

In a research article, an original study is conducted by the authors. They collect and analyze data, sharing their methods and results, and then draw conclusions from their analysis. The kind of study performed can vary (surveys, interviews, experiments, etc.), but in all cases, data is analyzed and a new argument is put forth. Research articles are considered primary sources.

• Note: research articles will often contain a section titled "literature review" - this is a section that looks at other existing research as a foundation for their new idea. Simply seeing the words "literature review" does not automatically mean an article is a review article- it is important to look closer

Below is a screenshot of the abstract of the article Effectiveness of Health Coaching in Diabetes Control and Lifestyle Improvement: A Randomized-Controlled Trial, with some words underlined that let us know that a study was conducted and that this is a research article.

Review Articles

A review article gathers multiple research articles on a certain topic, summarizing and analyzing the arguments made in those articles. A review article might highlight patterns or gaps in the research, might show support for existing theories, or suggest new directions for research, but does not conduct original research on a subject. Review articles can be a great place to get an overview of the existing research on a subject. A review article is a secondary source.

• Looking in the reference section of a literature or systematic review can be a good place to find original research studies.

Below is a screenshot of the abstract of the article The Effect of Dietary Glycaemic Index on Glycaemia in Patients with Type 2 Diabetes: A Systematic Review and Meta-Analysis of Randomized Controlled Trials, with words underlined that clue us in that this is a review article.

Tips for identifying article type

Start by looking at the abstract to determine if a source might be a research article or a review article. If you're not sure after looking at the abstract, find the methods section for the source - what methods did the authors use? If they mention searching databases, it's most likely a review and if they mention conducting an experiment, survey, interview, etc., it's most likely a research article. If you're still unsure, feel free to reach out to a librarian and ask! 

Let's Practice

Below are two different scholarly articles. Look at the abstract and the methods section- Which one is an original research study? Which one is a literature review?
