Compare Articles

scholarly articles

Both empirical articles (original research) & literature reviews are:

  • published in journals
  • often peer-reviewed
  • written by experts in the field

They are different in one important way:

Empirical articles report the findings of a research study, while review articles assess the findings of a variety of studies on a topic.

Empirical Articles

Empirical articles are based on an experiment or study.  The authors will report the purpose of the study, the research methodology, and results. This is a familiar structure for empirical articles (IMRAD):

  • introduction
  • methods
  • results
  • discussion

In describing the purpose of their study, authors will present a mini literature review to discuss how previous research has led up to their original research project.

Example: The prevalence of sleep disorders in college students: Impact on academic performance

Limiting to Empirical Articles

In PsycINFO, use the Methodology limiter to narrow to empirical study (original research).

You may also want to try clinical case study, clinical trial, or treatment outcome depending on your topic.

APA describes the methodology field values found in the PsycInfo and PsycArticles databases.

  • In addition to the Empirical Study limiter, there are also limiters for Clinical Case Study and Treatment Outcome/Clinical Trial.

Review Articles

Review articles summarize or synthesize content from earlier published research and are useful for surveying the literature on a specific research area. Review articles can lead you to empirical articles.

There are several types.

  • narrative: a literature review that describes and discusses the state of the science of a specific topic or theme.
  • systematic: a comprehensive review of all relevant studies on a particular topic/question. The systematic review is created by following an explicit methodology for identifying/selecting the studies to include and evaluating their results.
  • meta-analysis: the statistical procedure for combining data from multiple studies. This is usually, but not always, presented with a systematic review.

Example: Let's talk about sleep: a systematic review of psychological interventions to improve sleep in college students

Limiting to Lit Reviews

In PsycINFO, use the Methodology limiter to narrow to literature review.

You may also want to try systematic review or meta analysis.
