PSY540 Research Guide: Systematic literature review

Evidence based practice - an introduction : Literature reviews/systematic reviews

Evidence based practice - an introduction is a library guide produced by the Library for undergraduates. The information contained in the guide is also relevant for post graduate study and will help you to understand the types of research and levels of evidence required to conduct evidence based research.

A Systematic Review, or a Systematic Like Review?

Researchers, academics and librarians all use various terms to describe different types of literature reviews, and there is often inconsistency between the ways the types are discussed. Here are a couple of simple explanations.

The image below describes common review types in terms of speed, detail, risk of bias and comprehensiveness:

Description of the differences between review types in image form

"Schematic of the main differences between the types of literature review" by Brennan, M. L., Arlt, S. P., Belshaw, Z., Buckley, L., Corah, L., Doit, H., Fajt, V. R., Grindlay, D., Moberly, H. K., Morrow, L. D., Stavisky, J., & White, C. (2020). Critically Appraised Topics (CATs) in veterinary medicine: Applying evidence in clinical practice.

The table below has been adapted from a widely used typology of fourteen types of reviews, (Grant & Booth, 2009).  Here are four of the most common types:

REVIEW TYPE DESCRIPTION TIMEFRAME NO. OF REVIEWERS
Systematic review Seeks to systematically search for, appraise, and synthesise research evidence so as to aid decision-making and determine best practice. Can vary in approach, and is often specific to the type of study, which include studies of effectiveness, qualitative research, economic evaluation, prevalence, aetiology, or diagnostic test accuracy. 8 months to 2 years 2 or more
Rapid review Assesses what is known about an issue by using a systematic review method to search and appraise research and determine best practice. 2-6 months 2
Scoping review Assesses the potential scope of the research literature on a particular topic. Helps determine gaps in the research. (See the page in this guide on Scoping reviews.) 2-8 weeks 1-2
Traditional (narrative) literature review Identifies and reviews published literature on a topic, which may be broad. Typically employs a narrative approach to reporting the review findings. Can include a wide range of related subjects. 1-4 weeks 1

Systematic review

Systematic literature review

A systematic literature review (SLR) identifies, selects and critically appraises research in order to answer a clearly formulated question (Dewey, A. & Drahota, A. 2016). The systematic review should follow a clearly defined protocol or plan where the criteria is clearly stated before the review is conducted. It is a comprehensive, transparent search conducted over multiple databases and grey literature that can be replicated and reproduced by other researchers. It involves planning a well thought out search strategy which has a specific focus or answers a defined question. The review identifies the type of information searched, critiqued and reported within known timeframes. The search terms, search strategies (including database names, platforms, dates of search) and limits all need to be included in the review.

Pittway (2008) outlines seven key principles behind systematic literature reviews

  • Transparency
  • Clarity
  • Integration
  • Focus
  • Equality
  • Accessibility
  • Coverage

Systematic literature reviews originated in medicine and are linked to evidence based practice. According to Grant & Booth (p 91, 2009) "the expansion in evidence-based practice has lead to an increasing variety of review types". They compare and contrast 14 review types, listing the strengths and weaknesses of each review. 

Tranfield et al (2003) discusses the origins of the evidence-based approach to undertaking a literature review and its application to other disciplines including management and science.
