Literature reviews are critical components of research papers, theses, dissertations, and other scholarly works. They serve to summarize, analyze, and synthesize existing literature on a specific topic. Depending on your research objectives and the nature of your study, there are several types of literature reviews you can consider. Let's start with a few considered by Lenaars et al (2021), in their article, "Reviewing the animal literature: how to describe and choose between different types of literature review",:
Let's dive a little further into these literature review types (and explore a few more!).
This type provides a comprehensive overview of existing literature on a particular topic. It summarizes and organizes the key concepts, theories, and findings in a narrative format. In a narrative review, there isn't any statistical analysis or a systematic search strategy.
A systematic review involves a systematic and rigorous search process to identify all relevant studies on a specific research question or topic. It often includes predefined inclusion and exclusion criteria. Statistical methods may be used to synthesize the results of selected studies (meta-analysis).
Meta-analysis is a quantitative method used within systematic reviews. It involves statistically analyzing and synthesizing the results from multiple studies to derive a pooled effect size or estimate.
A scoping review aims to map the existing literature on a broad research question or topic. It identifies the main sources, themes, and gaps in the literature, and is particularly useful when a topic is complex and diverse.
In a critical review, the emphasis is on evaluating and critiquing the quality, methodology, and findings of existing studies. It assesses the strengths and weaknesses of the research and identifies areas where further investigation is needed.
An integrative review combines both qualitative and quantitative research to provide a more comprehensive understanding of a particular phenomenon. It may include a mix of methodologies to synthesize evidence.
This type focuses on reviewing and analyzing theories and conceptual frameworks related to a specific topic. It helps establish the theoretical foundation for your research.
A historical review explores the evolution of a topic or concept over time by tracing the development of ideas and theories and may highlight key milestones.
This type examines various research methods and approaches used in previous studies related to your topic. It helps you select appropriate methodologies for your research.
An argumentative review presents a particular perspective or argument on a topic. It may aim to persuade the reader of a specific viewpoint or hypothesis based on the existing literature.
