Recognizing primary or original research articles

Most of the peer-reviewed articles you'll find using PubMed, Google Scholar, ScienceDirect, APPsearch, CINAHL, and other search interfaces will be original or primary research.  Not all.  You'll often see reviews, systematic reviews, and meta-analyses (and maybe evidence summaries, guidelines, or position statements).  You might also see editorials, commentary, news.    All these are not considered original or primary.

Look for the standard format: short introduction, methods, results, and conclusions.  If your article is in this format, it's not editorials, commentary, news.  It's probably original research.  But,

Look for terms like these, especially in the title or abstract: review, systematic review, meta-analysis, evidence summary, guideline, or position statement.  If you don't see those, it's almost certainly original research.

Look for the standardized format, especially whether there is a Methods or Methodology section.  Then look for the terms like review.  If you see a methods section and you cannot see the article described as a review (or similar), it's probably original.

This is a very simplified approach, so please fell free to ask me to look at any articles with you.  John Wiswell, .



More details, if you need them

One additional area of confusion is this.  Some original research articles use data collected systematically by governments and other entities.  Other original research articles are based on original data, data that's not collected or measured or described elsewhere.  But original research does not have to have to start with original data.

Note that in some journals like the Journal of the Academy of Nutrition and Dietetics, original research is labelled "Original Research."  (This journal has an unusually high proportion of articles that are not original, but they're pretty well labelled.)

Original research where researchers collect or create their own data

Frymark, E. E., Stickford, J. L., & Farris, A. R. (2020). A Nutritional and Environmental Analysis of Local Food Pantries Accessible to College Students in Rural North Carolina. Journal of Appalachian Health, 2(2), 24–35.    Link to full text
Original research where researchers use already collected data

Not original research -- These researchers find and review original research done by others.

NUT 4200 assignment -- 2022

One detail -- 3 peer-reviewed articles, must be the original studies, not review papers

See box below titled, "Recognizing original research articles."

Also, (video) how to filter for original articles in ScienceDirect, Web of Science, and PubMed.  You cannot really filter with a button in APPsearch or Google Scholar.  But you should be beginning to recognize the original versus review anyway. (Note: I claim in this video that I eliminated everything but original studies from my PubMed results, but that's not true.  I filtered out only reviews, including systematic reviews and meta-analyses.  There would still be editorials and a small variety of other things.)

Special services for "AppState Online" students

Almost all of our journals and electronic resources are available online to the entire AppState community.  We're mostly buying ebooks for programs with many "distance" students.

But we do have additional services for you.  As an "AppState Online" student, you may have physical books mailed to you.  Click the Request button in the Library Catalog to trigger this.  It will be mailed to your home with a postage paid return label.  Make sure to update your University address!

Also, you might occasionally find an old article that we only have in paper volumes.  You can request that these articles be scanned and emailed to you.  Use our ILLiad system.

Also,  everyone can use ILLiad in general to request articles, books, and theses that we do not have immediate access to.  ILLiad is our InterLibrary "Loan" service.  It's generally 24-48 hours for articles.

Also, contact me as needed.
