Writing a Systematic Literature Review Investigating concepts associated with psychology requires an indefinite amount of reading.
Hence, good literature reviews are an inevitably needed part of providing the modern scientists with a broad spectrum of knowledge. In order to help, this blog post will introduce you to the basics of literature reviews and explain a specific methodological approach towards writing one, known as the systematic literature review.
THE BASICS Literature review is a term associated with the process of collecting, checking and re analysing data from the existing literature with a particular search question in mind.
The latter could be for example: Does brief psychotherapy produce beneficial outcomes for individuals diagnosed with agoraphobia? What personality traits are most commonly associated with homelessness in the modern literature?
A literature review a defines a specific issue, concept, theory, phenomena; b compiles published literature on a topic; c summarises critical points of current knowledge about the problem and d suggests next steps in addressing it. Literature reviews can be based on all sorts of information found in scientific journals, books, academic dissertations, electronic bibliographic databases and the rest of the Internet.
Besides scientific literature, literature reviews often include the so called gray literature. This refers to the material that is either unpublished or published in non-commercial form e.
Excluding it completely from a literature review is inappropriate because the search should be always as complete as possible in order to reduce the risk of publication bias.
However, when reviewing the material on for example Google ScholarScience. When performing literature reviews, the use of appropriately selected terminology is essential, since it allows the researchers much clearer communication. In psychology, without some commonly agreed lists of terms, we would all get lost in the variety of concepts and vocabularies that could be applied.
Other tools to make search strategy more comprehensive and focused are also truncations — a tool for searching terminologies that have same initial roots e. It is worth noting that the databases slightly differ in how they label the index terms and utilize specific search tools in their systems.
Among authors, there is not much coherence about different types of literature reviews but in general, most recognize at least two: The main difference between them is situated in the process of collecting and selecting data and the material for the review.
Systematic literature review, as the name implies, is the more structured of the two and is thought to be more credible. Systematic protocol of the systematic literature review can be therefore understood as an optional solution for controlling the incomplete and possibly biased reports of traditional reviews.
In other words, to reduce bias, the rationale, the hypothesis, and the methods of data collection are prepared before the review and are used as a guide for performing the process. Just like it is for the traditional literature reviews, the goal is to identify, critically appraise, and summarize the existing evidence concerning a clearly defined problem.
Furthermore, they include the possibility of evaluating consistency and generalization of the evidence regarding specific scientific questions and are, therefore, also of great practical value within the psychological field.
Systematic literature reviews include all or most of the following characteristics: The process of performing a systematic literature review consists of several stages and can be reported in a form of an original research article with the same name i.
Start by clearly defining the objective of the review or form a structured research question. Place in the research article: Example of the objective: The objective of this literature revision is to systematically review and analyse the current research on the effects of music on the anxiety levels of children in hospital settings.
Example of a structured research question: What are the most important factors associated with the development of PTSD in soldiers?
In the title, identify that the report is a systematic literature review.
Clearly specify the methodology of the review and define eligibility criteria i. The search should be extensive. Examples of inclusion criteria: Publication was an academic and peer-reviewed study.
Publication was a study that examined the effects of regular physical exercise intervention on depression and included a control group. Examples of exclusion criteria: Publication was involving male adults.
Studies that also examined non-physical activities as interventions. Studies that were only published in a language other than English.
The eligibility criteria sometimes fit to be presented in tables. Retrieve eligible literature and thoroughly report your search strategy throughout the process.
Ideally, the selection process is performed by at least two independent investigators.In composing a literature review, it is important to note that it is often this third layer of knowledge that is cited as "true" even though it often has only a loose relationship to the primary studies and secondary literature reviews.
