Narrative review, also known as a narrative synthesis, is a type of research method used to analyze and summarize scientific literature. Unlike systematic reviews which employ strict methodology and statistical analysis, narrative reviews provide a more subjective analysis of the literature. This method of review is becoming increasingly popular as it allows for the inclusion of a vast array of studies and the synthesis of findings from various sources.
Narrative reviews are particularly useful when dealing with complex or emerging topics where standard methodologies may not be available. They provide a broad analysis of the evidence as well as contextualized insight into the topic at hand. Due to the subjectivity involved in narrative reviews, they are also useful in highlighting gaps in knowledge and potential areas for further research. In addition, they can be used to identify patterns or trends in the literature that may not have been captured in systematic reviews or meta-analyses.
Definition of Narrative Review
A narrative review is a type of research methodology that aims to provide a comprehensive summary and analysis of existing literature on a particular subject. Unlike systematic reviews, narrative reviews do not follow a strict protocol or use a set of pre-defined criteria to select studies for inclusion. Instead, they rely on the expertise and judgment of the reviewers to select papers that are relevant and meaningful in answer to the research questions.
Narrative reviews are most commonly used in the social sciences, humanities, and occasionally in biomedical research where the available evidence is less structured, and research questions are not well-defined. Narrative reviews can provide a rich source of information and are useful when examining complex phenomena that might be overlooked or inadequately identified using traditional quantitative methods.
Some characteristics of narrative reviews include:
- Focus on a specific research question or topic.
- Inclusion of non-randomized studies, including qualitative research.
- No formal protocol or criteria for inclusion or exclusion of studies.
- Synthesis of evidence through narrative or thematic analysis.
One of the main advantages of narrative reviews is their flexibility, allowing reviewers to accommodate the diverse research methodology while still providing insights into the relevant literature. However, critics argue that without having a systematic approach, there is a risk of bias and subjectivity in the selection process, interpretation of the evidence, and conclusion made.
Distinction between Systemic and Narrative Review
When it comes to conducting a literature review in research, researchers have two options – Systemic Review and Narrative Review. Both types are designed to answer research questions and synthesize the existing knowledge. However, they differ in the methodology and strategy used to accomplish this task.
Let’s find out the primary differences between Systemic and Narrative Review.
- Methodology: Systemic Review follows a systematic and transparent process to identify, select, assess, and synthesize relevant literature. It uses a pre-defined search strategy, including a set of inclusion and exclusion criteria, and critically assesses the quality of studies. In contrast, Narrative Review involves a more flexible and intuitive approach to literature searches. It is based on the author’s subjective judgment and interpretation of the available evidence.
- Objective: Systemic Review aims to provide a comprehensive and unbiased summary of the literature concerning a specific research question. It intends to minimize bias and maximize the reliability and validity of the results. On the other hand, Narrative Review aims to provide a general overview or narrative of the literature in a specific field, rather than a comprehensive synthesis of the evidence.
- Types of Evidence: Systemic Review mainly involves quantitative studies, such as randomized controlled trials and cohort studies, which provide the highest level of evidence. It may also include qualitative studies in some cases. In contrast, Narrative Review may include any type of literature, such as case reports, expert opinions, commentaries, and editorials.
In conclusion, choosing between Systemic and Narrative Review depends on the research questions, objectives, and available resources. While Systemic Review provides a rigorous and transparent approach to literature synthesis, it requires more time and resources. Narrative Review, on the other hand, may be suitable for preliminary exploration and hypothesis generation, but its findings may be less reliable because of the potential for bias.
Process of Conducting a Narrative Review
A narrative review is a type of research that involves combining studies, articles, and reports about a particular topic to produce an overview or summary of the information available. This subsection will discuss the process of conducting a narrative review.
- Developing the research question: The first step in conducting a narrative review is to develop a research question. The question should be clear, concise, and focused, and it should indicate the topic to be reviewed and the specific aspect that is being investigated. For example, “What is the effectiveness of various treatment options for chronic pain among elderly patients?”
- Identifying relevant studies: Once the research question has been developed, the next step is to identify relevant studies for inclusion in the review. This can be done by conducting a comprehensive search of relevant databases, such as PubMed and Google Scholar, and by manually searching relevant journals and reference lists. Inclusion and exclusion criteria should be established to ensure that the studies retrieved are relevant to the research question.
- Assessing the quality of studies: After the relevant studies have been identified, each study’s quality should be assessed. This involves evaluating the study’s methodology, data collection, and analysis methods in terms of their validity, reliability, and generalizability. This step ensures that only high-quality studies are included in the review.
Once all the relevant studies have been identified and their quality assessed, the next step is to systematically summarize and synthesize the information obtained from the studies. This includes analyzing the data and drawing conclusions on the topic under review.
Reporting the Narrative Review
Reporting the results of a narrative review is an important final step. A comprehensive report should be written that includes details of the search process, inclusion and exclusion criteria, and quality assessment of the studies. It should also describe the key findings of the review and any limitations or biases that may have influenced the results. The narrative review report should follow a clear and logical structure that enables the reader to understand the research question, methods used, and conclusions reached.
Conclusion
The process of conducting a narrative review involves developing a clear research question, identifying relevant studies, assessing the quality of the studies, and producing a comprehensive report of the results. This type of research can provide a valuable overview of the available evidence on a particular topic, making it an important tool for clinicians, policy-makers, and researchers.
| Steps in Conducting a Narrative Review | Description |
|---|---|
| Developing the research question | Defining the specific topic to be reviewed and the aspect being investigated. |
| Identifying relevant studies | Conducting a comprehensive search of relevant databases and manually searching relevant journals and reference lists. |

Comparison of Narrative Review with other Research Reviews
When it comes to research reviews, there are several types available, including systematic reviews, scoping reviews, and meta-analyses. While each type has its own strengths and weaknesses, narrative reviews stand apart in several ways:
- Narrative reviews are less structured than other review types. Unlike systematic and scoping reviews, which follow a strict protocol, narrative reviews offer more flexibility to the author. This can be both an advantage and a disadvantage, as it allows the author more freedom to explore different perspectives but can also lead to bias or inconsistencies if not approached with care.
- Narrative reviews typically rely on qualitative analysis. While other review types may focus on quantitative data and statistical analysis, narrative reviews often prioritize a qualitative understanding of the study topic. This can be helpful in providing a more holistic, nuanced perspective on complex issues.
- Narrative reviews may have a broader scope. While systematic reviews and meta-analyses typically focus on a single research question or set of questions, narrative reviews may provide a more comprehensive overview of a particular topic or field. This can be useful in identifying gaps in knowledge, identifying key themes or trends, and providing a high-level overview of a field or research area.
However, it’s important to note that narrative reviews do have limitations compared to other types of reviews. For example, they can be more prone to bias or inconsistencies, as the author has more freedom in selecting which studies to include and how to analyze them. Additionally, narrative reviews may not be as replicable as more structured review types, which can impact their rigor and credibility.
Overall, narrative reviews are a valuable tool in research and can provide unique insights and perspectives on a given topic. However, they should be approached with care, and their limitations should be considered when interpreting their findings.
Criticism of Narrative Review
Narrative reviews have become increasingly popular in recent years, as they offer a descriptive evaluation of literature on a particular research topic. However, they have also received criticism in the research community. Some of the major criticisms of narrative reviews include:
- Subjectivity: Narrative reviews heavily rely on the author’s interpretation of the literature, which can be biased and subjective. This can result in a lack of objectivity in the review.
- Lack of Reproducibility: Due to the subjective nature of narrative reviews, it can be difficult for other researchers to reproduce the same findings or arrive at the same conclusions.
- Incomplete Inclusion Criteria: Unlike systematic reviews, narrative reviews do not have a clear set of inclusion criteria, which can result in important studies being excluded from the review.
Additionally, narrative reviews may lack the rigor and transparency of other types of reviews, such as systematic reviews. They may also be more prone to the influence of author biases and conflicts of interest.
Despite these criticisms, narrative reviews can still be a valuable tool for synthesizing literature and providing a broad overview of a research topic. However, it is important to approach them with a critical eye and be aware of their potential limitations and biases.
| Criticisms | Consequences | Potential Solutions |
|---|---|---|
| Subjectivity | Lack of objectivity and reproducibility | Use clear and transparent inclusion criteria, involve multiple reviewers, and report potential biases |
| Lack of Reproducibility | Difficulty in reproducing findings or arriving at the same conclusions | Provide clear methods and inclusion criteria, involve multiple reviewers, and report limitations |
| Incomplete Inclusion Criteria | Important studies may be excluded from the review | Use clear and transparent inclusion criteria and involve multiple reviewers to ensure all relevant studies are included |
It is important to address these criticisms and adopt best practices to ensure that narrative reviews are conducted and reported in a rigorous and transparent manner.
The Role of Narrative Review in Evidence-Based Practice
When it comes to conducting research, there are several types of review methods that can be used. One of these methods is a narrative review. Below, we’ll explore what a narrative review is and the role it plays in evidence-based practice.
What is a Narrative Review?
A narrative review is a type of literature review that summarizes and synthesizes current research on a particular topic or research question. Unlike a systematic review that follows a specific protocol, a narrative review is conducted in a more flexible and subjective manner.
Instead of relying on a specific methodology to search for and evaluate studies, the author of a narrative review will conduct a broader search of available literature and then synthesize the information in a way that is consistent with their research question or area of interest.
The Role of Narrative Review in Evidence-Based Practice
- A narrative review can help identify gaps in the research. By synthesizing the available literature, a narrative review can reveal areas where research is lacking or where further investigation is needed. This information can guide future research and help researchers prioritize their efforts.
- A narrative review can provide context for new research. By summarizing the existing literature on a particular topic, a narrative review can contextualize new research and help clarify its significance. This can be particularly useful in emerging fields where research is still developing.
- A narrative review can be used to inform evidence-based decision making. By synthesizing current research, a narrative review can help inform clinical decision making or guide policy decisions. This can be particularly useful in healthcare settings where evidence-based practice is becoming increasingly important.
The Advantages and Disadvantages of Narrative Reviews
Like any research method, narrative reviews have their advantages and disadvantages. Some of the advantages of narrative reviews include their flexibility and the fact that they can provide a broader perspective on a particular topic. Additionally, narrative reviews can be useful in exploring questions that may not be easily addressed through more structured methods.
However, some of the disadvantages of narrative reviews include the potential for bias and the fact that they may not be as rigorous as other review methods. Additionally, because narrative reviews are more subjective, it can be difficult to replicate the results or assess their reliability.
| Advantages | Disadvantages |
|---|---|
| Flexible | Potential for bias |
| Provides a broader perspective | May not be as rigorous as other review methods |
