Various forms of literature review
Literature reviews are persistent all through various academic disciplines, and hence you can use various approaches to efficiently organize and draft literature review. Here are few of the types:
Systematic or Meta-Analysis Literature Review:
The systematic review refer to vigorous way of comparing quantitative research and then begin as per the well-defined steps, that involve statistical analysis of the pooled result of research studies. Moreover, this statistical analysis precisely called as meta-analysis, though it has become interchangeable with systematic review.
Systematic review:
- It identifies, evaluates and then synthesizes evidence to respond a particular research question.
- Applies a meticulous approach which detail time frame of specific chosen literature and critique method and analysis, with well-defined an explicit methods in order to reduce bias and increase the reliability.
- Takes in as comprehensive an amount of research studies as probable from the findings of both published and unpublished such as "grey literature".
A meta-analysis:
- It systematically discovers, assesses and synthesizes data from findings of large body using statistical techniques and analysis.
- It tends to correct flaws of narrative or traditional reviews by synthesizing a large amount of studies.
- Integrates and take out conclusions on research findings, also look for identifying relationships and broad patterns between studies.
Traditional or Narrative Literature Review:
A narrative or traditional review outlines contrasting primary studies from which conclusions can be made into a holistic interpretation accompanied by the author's own theories, experience, or models:
- It gives background in order to understand contemporary knowledge
- It criticizes, summarize and produce conclusion from body’s knowledge
- Figure out the inconsistencies or gaps that are required to be corrected or filled through further study and research.
- Helps to clarify the research question and topic
- It holds the flaw of being slighter useful as extra information becomes available.
Meta-Synthesis Literature Review
While meta-analysis is an approach used to test a hypothesis, however a meta-synthesis tries integrating results from numerous different but inter-related qualitative studies. Moreover, this technique allows interpreting rather than aggregates, contradicting to meta-analysis of quantitative studies:
- It aims to bring together, re-analyze, juxtapose and integrate findings from various qualitative studies utilizing non-statistical techniques.
- It looks for discovering or providing new conceptions, interpretations or theoretical developments.
- Integrate numerous studies to figure out common key elements and themes.
- Utilizes findings from grounded theory, phenomenological or ethnographic studies.
Scoping Review
It is mostly used at the beginning of a dissertation, article or research proposal. As conducted prior the research begins, it sets the stage for this research by underlining the gaps in the literature, also explain why the research should be conducted, which is clearly presented in the rest of the content. Scoping review mainly provide an initial indication of the nature and potential size of the existing literature on evolving topic. It allows examining the nature, range, extent of research activities in specific area, determining the significance of undertaking full systematic review or finding research gap in present literature. The main objective is to conclude with the presentation of in-depth research agenda for future study along with implication for both research and practice.
Mapping Reviews
The central goal of this form is to demonstrate the degree to which body of knowledge in specific study topic discloses any interpretable trend or pattern with respect to pre-existing theories, propositions, findings or methodologies. Contrasting with narrative reviews, it follows a transparent and systematic procedure, involving searching, classifying and screening studies. Furthermore, authors of descriptive reviews draw from each research study definite characteristics of interest, for instance research methods, publication year, data collection direction and techniques or the power of research outcomes ( which could be positive, negative, or non-significant) in the form of frequency analysis to generate quantitative results .
What is a systematic literature review
Systematic literature review is one of the types of literature review that aims to aggregate, evaluate and synthesize in a single source all empirical evidence which meet set of earlier identified eligibility criteria, as a way to answer often narrow and clearly formulated research question on specific topic of interest to support evidence-based practice. They follow carefully to explicit scientific principles and hard methodological guidelines which are aimed at reducing systematic and random errors that leads to deviations from the truth in inferences or results. The usage of methods (explicit) let systematic reviews to aggregate a great body of research evidence, and evaluate whether relationships or effects are in the similar direction or in same general magnitude. It also explains possible discrepancies between study results, and defines the strength of the complete evidence for every product of interest based on the general consistency among them and quality of included studies. The main procedures of a systematic review include
- Developing a review question and formulating search strategy grounded on explicit inclusion criteria for the recognition of eligible studies (typically discussed in the context of a comprehensive review protocol).
- Searching for qualified studies that use various information sources and databases, including grey literature sources but without any restrictions on language.
- Choosing studies, extracting the data, and evaluating risk of bias in an identical manner utilizing two independent reviewers to neglect systematic or random errors in the process.
- Analyzing the data using qualitative or quantitative methods.
- Presenting results or outcomes in the summary of findings tables.
- Interpreting results and generating conclusions.
