Have you ever wondered how literature review is written or you have difficulties completing the literature review section of your research paper? It can be difficult because it is not always clear what information they need, or where to find it.
This article will cover the basics of writing a literature review for your research paper, and provide some tips on finding sources.
A literature review is a summary of what has been published on your topic. It is also referred to as the review of related literature in research and academic papers. It’s often written as the first part of research or an academic paper, but it can also be used to summarize and evaluate existing work in other disciplines before drawing new conclusions.
The goal of this process is to synthesize all of the available information about a particular subject into one document so that others may more easily access it. It will be used by you and other researchers in order to understand the existing knowledge about the topic, which can then be synthesized and applied to your own work.
A good literature review should provide a summary of previous studies on a subject as well as clearly defined objectives for future research.
Also referred to as systematic review of literature, SLR is a research study that provides an overview of what has been done in a particular area. It uses multiple sources to collect all the information and presents it in a coherent manner.
In other terms, it employs explicit, systematic methods which involve searching for articles in electronic databases using predefined search terms or by following the guidelines established by an individual indexing service.
The reviewers then read each article independently and assess its relevance with respect to their original aim before deciding whether it should be included in the review. SLRs are used for both academic and professional purposes such as conducting research or providing evidence-based practice within healthcare organizations.
Systematic Literature Review (SLR) is a way to synthesize the research on an issue. This process can be broken down into three broad categories: search strategy, data extraction and synthesis of findings.
In order for your work to be sound you need to have a clear purpose statement that guides your search for information relevant to your topic area as well as criteria for determining which studies are useful sources of information and which ones are not.
When writing a systematic literature review, it’s important to identify the key components and major findings in each article that you’re reviewing. This will help ensure your audience understands what the research found and how it relates to your topic.
What is grey literature? It is a subset of literary work which falls outside traditional publishing channels (i.e., peer reviewed journals). These pieces are often published by private companies and organizations and are not generally found in libraries or databases like PubMed and Medline.
The non-traditional sources that fall under grey literature include such forms as newsletters, reports from industry experts or unpublished academic data.
Here are the 13 Steps of Writing a literature:
Example: ”I want to know what causes people who have been diagnosed with schizophrenia.”
Example: “What is the role of genetic factors in schizophrenia?”
Examples: Genes; Environment; Mental Illness (Schizophrenia)
Examples: PubMed; ScienceDirect
Example: “Schizophrenia” OR “genes” NOT “mental illness” OR “environment”
Example: “teenagers” OR “teens” NOT “adults” OR teens ages 50+
Examples: None given; around three or four per keyword phrase
Examples: None given; one sentence per article
Example: “The purpose of this review was to summarize genetic studies examining specific childhood maltreatment types with participants diagnosed with adult psychosis. [It] found evidence for association between physical abuse during childhood and adulthood psychotic disorder.”
Examples: None given; around three or four per keyword phrase
Example: “[The article] examined if physical abuse during childhood increased risk of adult psychotic disorder and found evidence that it does.”
For example: “When investigating bipolar disorder susceptibility genes, we would want to find scholarly articles about the human genome, genetics research on bipolar disorder in humans and other mammals, X-chromosome linkage studies of bipolar families with a female pedigree history.
There are many questions that remain unanswered relating to how mood disorders such as Bipolar Disorder (BD) develop. This is due partly simply because there has been very little genetic data collected for BD patients compared to its more common counterpart Major Depressive Disorder (MDD)
Genetic studies of mood disorders have not been well-powered for detecting individual susceptibility genes, and to date no replicated linkage or association finding has emerged from a genome-wide scan.” Even with many unanswered questions relating to the cause of BD, there are still plenty of avenues in which research can be conducted.”
A good literature review should contain the following Element: Introduction, background information on the topic (literature search), research questions/hypotheses, study design, findings and conclusion.
The purpose of the introduction section of the literature review should be to inform the reader about where you got your information from (i.e., journals, books) so that he can follow up by reading those articles himself if interested or needed to do further research into the topic before coming up with his own arguments/claims/conclusions at later stages when writing thesis statements and conclusions sections.
“I am conducting a cross-sectional study using a sample size balanced between males and females from three different age groups, 18-25 (n = 100), 26-40 (n=100) 41+ years old(N= 100).”
Here are some Review of related literature (RRL) paragraph examples:
“This systematic literature review was conducted to identify and synthesize the published evidence for complementary approaches that have been used in treating individuals with autism spectrum disorder. From the identified sources, 32 articles were selected for review. The vast majority of these studies are small in size and more research is needed to substantiate or refute current findings. The studies reviewed were generally well designed and yielded data that provide some preliminary information on efficacy. The approaches in the literature ranged from chiropractic manipulative treatment, dietary supplementation, nutritional counseling, neurotherapy/EEG biofeedback therapy to sensory integration training.”
A systematic literature search was performed using PubMed Central with keywords autism AND (integrative OR complementary). From the identified sources, 16 papers were considered eligible for inclusion into this study. All included papers reported on treatment outcomes following use of an integrative approach that incorporated both conventional and alternative therapies. These results suggest that there may be some efficacy to combining conventional medicine and therapy with complementary approaches such as acupuncture which have been commonly used by individuals seeking treatment for their ASD symptoms without access to other options.
Diversity in college textbooks has increased by 14% over three decades. In 1990, African American authors made up just 0.59% of all textbook selections while Native Americans represented 0.31%. By 2010 these numbers had risen to 0.71% (African American) and 0.51%.
A good, thorough literature review will provide readers with an overview of what other scholars have done in this field. It should summarize their main findings as well as how they conducted their studies which could be useful if you are planning on replicating it for yourself.
This article has provided you with information about what a literature review means, how to write one, steps involved in writing one and elements that make up good ones. We hope this helps!
