Finding Credible Sources of Information

How to Find Accurate Information

How do I know which COVID-19 information sources are accurate?

It can be hard to know which sources of information you can trust. Before learning more about COVID-19 on the internet, check that the information comes from a credible source (e.g., federal or state agency, academic institution) and is updated on a regular basis. The National Center for Complementary and Integrative Health (NCCIH) and Purdue University offers information on Finding and Evaluating Resources1 and Evaluating Digital Resources2 to ensure the content you find is credible.

What about peer-reviewed articles?

Accurate information about COVID-19 may be found in peer-reviewed articles published in credible scholarly journals. Before formal publication in a scholarly journal, scientific and medical articles go through “peer review” for certification. To be certified by peer review, a study or article will first need to be evaluated by several subject matter experts. This helps find possible weaknesses in the study's assumptions, methods, and conclusions in an unbiased, independent, and critical way before it is formally published. Only articles that meet good scientific standards (e.g., acknowledge and build upon other work in the field, rely on logical reasoning and well-designed studies, back up claims with evidence3) are then accepted for formal publication.

Peer reviewed articles should not be confused with “preprints.” Because peer review and certification by a journal can take a long time, authors can make their manuscripts available as preprints for scientists to see, discuss, and comment on their findings. Therefore, preprints are not credible sources as they have not been finalized by authors, might contain errors, and report information that has not yet been accepted or endorsed in any way by the scientific or medical community.

The Art of reading a journal article: Methodically and effectively4 is a helpful resource for those looking for more in-depth support during the research process. See below for some examples of credible scholarly journals and resources that publish peer-reviewed articles.
 

What about sample size?

The sample size (the number of patients or other experimental units) is very important for getting statistically significant results and running a study successfully for quantitative research. Samples should not be too big or too small since both have limitations that can compromise the conclusions drawn from the studies. When reading an article, the reader should be on the alert to find out that the study they are reading was subjected to sample size calculation. In the absence of this calculation, the study's findings should be interpreted with caution since the researcher(s) may not have designed the study to consider the errors or limits of the sample size used.
