How to Read a Research Article: Part I

by David M. Bazett-Jones

This is the first part of a Guide to Reading Research Articles.

Research articles can be very difficult to read. Reading research is a skill that takes quite some time to be proficient at. This is why many people will read the abstract or conclusions of a study apply them with a broad brush, which is inherently invalid.

When attempting to read and understand an article, remember to read the article as a whole. Also, the authors have written it with the audience being scholars and colleagues. Therefore, a certain level of basic knowledge is assumed. Try not to become frustrated when an article to too complicated. You will learn, in time and with much practice, to extract the important aspects of an article without getting lost in the jargon.

What is Research?

Research is defined as a “systematic inquiry or investigation into a subject in order to discover or revise facts, theories, applications, etc (dictionary.com)”. The “systematic” aspect of research refers to how it is designed, which is very important. This is what separates research from other forms of “evidence”. Commonly, these other forms of “evidence” will be used to market a product (e.g. WBV machines). These may include (with descriptions):

Abstract
This is a summary of research but not an entire research article. Many times it is part of a research article published in a peer-reviewed, academic journal.; however, much care must be taken so that only the abstract is not solely relied upon as “evidence”.

Poster
This is usually a beefed-up summary that is presented at a conference by the researcher(s) as a poster. It may or may not be reviewed for quality prior to being accepted for presentation at that conference.

Presentation
This is similar to a poster but is presented in an oral format via software (e.g. Powerpoint). Again, it may or may not be reviewed for quality.

Case Study(ies)
These can be in the form of a single-person case study or a multiple-person case study (small number of people). These are typically not research because they are not systematically designed to answer a question, nor can results from one or a few individuals answer questions related to the general population.

While these are important first steps in the research process, they are no substitute for a research article. Also, these may be published in peer-review, academic journals; however, they are specific to the individual studied and should not be over-generalized.

Testimonial
Of course the most common of these come from celebrities. They are subjective interpretations of personal experiences and are not valid in a context outside of that individual. While they are very important to that individual, it may be that not all people like them will experience the same outcome.

Why do marketers use these? Because they work and help to sell the marketer’s product. Be the weariest of these forms of “evidence”.

Remember that these forms of “evidence” never can be substituted for a full research article in a peer-reviewed, academic journal.

Also, be aware that true research articles may be presented or listed; however, many times these are only loosely related to the product.

For example, a study performed on a different WBV machine than the one being marketed should be questioned. This is especially true when comparing lineal and pivotal studies.

Many marketers also present studies that use direct muscle vibration (very different than WBV) or industrial WBV to increase the number of studies listed under their “research” sections. These are only loosely related to WBV and the reader should be aware that these types of studies are not direct evidence of the treatment’s effectiveness.

Be leery of these marketing practices to pass these “studies” off as “proof” that something is safe or effective since quantity is never a substitute for quality.
