Importance of Narrowing the Research Topic

Whether you are assigned a general issue to investigate, must choose a problem to study from a list given to you by your professor, or you have to identify your own topic to investigate, it is important that the scope of the research problem is not too broad, otherwise, it will be difficult to adequately address the topic in the space and time allowed. You could experience a number of problems if your topic is too broad, including:

• You find too many information sources and, as a consequence, it is difficult to decide what to include or exclude or what are the most relevant sources.
• You find information that is too general and, as a consequence, it is difficult to develop a clear framework for examining the research problem.
• A lack of sufficient parameters that clearly define the research problem makes it difficult to identify and apply the proper methods needed to analyze it.
• You find information that covers a wide variety of concepts or ideas that can't be integrated into one paper and, as a consequence, you trail off into unnecessary tangents.

Strategies for Narrowing the Research Topic

A common challenge when beginning to write a research paper is determining how and in what ways to narrow down your topic . Even if your professor gives you a specific topic to study, it will almost never be so specific that you won’t have to narrow it down at least to some degree [besides, it is very boring to grade fifty papers that are all about the exact same thing!].

A topic is too broad to be manageable when a review of the literature reveals too many different, and oftentimes conflicting or only remotely related, ideas about how to investigate the research problem. Although you will want to start the writing process by considering a variety of different approaches to studying the research problem, you will need to narrow the focus of your investigation at some point early in the writing process. This way, you don't attempt to do too much in one paper.

Here are some strategies to help narrow the thematic focus of your paper :

• Aspect -- choose one lens through which to view the research problem, or look at just one facet of it [e.g., rather than studying the role of food in South Asian religious rituals, study the role of food in Hindu marriage ceremonies, or, the role of one particular type of food among several religions].
• Components -- determine if your initial variable or unit of analysis can be broken into smaller parts, which can then be analyzed more precisely [e.g., a study of tobacco use among adolescents can focus on just chewing tobacco rather than all forms of usage or, rather than adolescents in general, focus on female adolescents in a certain age range who choose to use tobacco].
• Methodology -- the way in which you gather information can reduce the domain of interpretive analysis needed to address the research problem [e.g., a single case study can be designed to generate data that does not require as extensive an explanation as using multiple cases].
• Place -- generally, the smaller the geographic unit of analysis, the more narrow the focus [e.g., rather than study trade relations issues in West Africa, study trade relations between Niger and Cameroon as a case study that helps to explain economic problems in the region].
• Relationship -- ask yourself how do two or more different perspectives or variables relate to one another. Designing a study around the relationships between specific variables can help constrict the scope of analysis [e.g., cause/effect, compare/contrast, contemporary/historical, group/individual, child/adult, opinion/reason, problem/solution].
• Time -- the shorter the time period of the study, the more narrow the focus [e.g., restricting the study of trade relations between Niger and Cameroon to only the period of 2010 - 2020].
• Type -- focus your topic in terms of a specific type or class of people, places, or phenomena [e.g., a study of developing safer traffic patterns near schools can focus on SUVs, or just student drivers, or just the timing of traffic signals in the area].
• Combination -- use two or more of the above strategies to focus your topic more narrowly.

NOTE : Apply one of the above strategies first in designing your study to determine if that gives you a manageable research problem to investigate. You will know if the problem is manageable by reviewing the literature on your more narrowed problem and assessing whether prior research is sufficient to move forward in your study [i.e., not too much, not too little]. Be careful, however, because combining multiple strategies risks creating the opposite problem--your problem becomes too narrowly defined and you can't locate enough research or data to support your study.

Picking a Topic and Keywords to Research your Topic

Whether you are writing a literature review as a standalone work or as part of a paper, choosing a topic is an important part of the process. If you haven't select a topic yet for your literature view or you feel that your topic is too broad, this page is for you!

The key to successfully choosing a topic is to find one that is not too broad (impossible to adequately cover) but also not too narrow (not enough has been written about it). Use the tools below to help you brainstorm a topic and keywords that then you can use to search our many databases. Feel free to explore these different options or  contact a Subject Specialist if you need more help!

Talk to your professor

A common challenge when beginning to write a research paper is determining how to narrow down your topic. 

Even if your professor gives you a topic to study, it will seldom be specific enough that you will not have to narrow it down, at least to some degree.

A topic is too broad to be manageable when you find that you have too many different, conflicting or only remotely related ideas. 

Although you will want to start the writing process by considering a variety of different approaches to studying the research problem, you will need to narrow the focus of your investigation at some point early in the writing process - this way you don't attempt to do too much in one paper.

Here are some strategies to help narrow your topic :

Aspect  -- choose one lens through which to view the research problem, or look at just one facet of it.

• e.g., rather than studying the role of food in South Asian religious rituals, explore the role of food in Hindu ceremonies or the role of one particular type of food among several religions.

Components  -- determine if your initial variable or unit of analysis can be broken into smaller parts, which can then be analyzed more precisely. 

• e.g., a study of tobacco use among adolescents can focus on just chewing tobacco rather than all forms of usage or, rather than adolescents in general, focus on female adolescents in a specific age range who choose to use tobacco.

Methodology  -- how you gather information can reduce the domain of interpretive analysis needed to address the research problem.

• e.g., a single case study can be designed to generate data that does not require as extensive an explanation as using multiple cases.

Place  -- generally, the smaller the geographic unit of analysis, the more narrow the focus.

• e.g., rather than study trade relations in North America, study trade relations between Mexico and the United States. 

Relationship  -- ask yourself how do two or more different perspectives or variables relate to one another. Designing a study around the relationships between specific variables can help constrict the scope of analysis. 

• e.g., cause/effect, compare/contrast, contemporary/historical, group/individual, male/female, opinion/reason, problem/solution.

Time  -- the shorter the time period of the study, the more narrow the focus.

• e.g., study of relations between Russia and the United States during the Vietnam War.

Type  -- focus your topic in terms of a specific type or class of people, places, or phenomena. 

• e.g., a study of developing safer traffic patterns near schools can focus on SUVs, or just student drivers, or just the timing of traffic signals in the area.

Cause  -- focus your topic to just one cause for your topic.

• e.g., rather than writing about all the causes of WW1, just write about nationalism.

When narrowing your topic, make sure you don't narrow it too much. A topic is too narrow if you can state it in just a few words.

For example:

• How many soldiers died during the first world war?
• Who was the first President of the United States?
• Why is ocean water salty?
• Why are Pringles shaped the way they are?

• Citing Your Sources

CHOOSING A TOPIC

Choosing your research topic is an important step in writing a literature review.

First, choose a strong topic and one you're interested in. You don't want a topic that is too narrow or one that has little or no research about it. Think of a topic that will have enough supporting articles relating to it. Is it significant enough that research has been done on it?

Try brainstorming . Writing different ideas down on paper can help your ideas flow. You also want a topic that piques your curiosity. Keep in mind you have to live with this topic over the course of an entire semester.

Try identifying 3 potential research topics. Consider related concepts. Then, perform a brief preliminary search on all three. From your three ideas, choose the one that is strongest. Are there enough articles available? Is the topic too general? Keep refining your topic so that it isn't too broad and general.

Finally, write down your topic in a statement form .

Here are a few helpful tips on how to choose a research topic:

• Choose a strong topic & one that interests you
• Try a preliminary search on your topic
• Refine your topic
• Write it out as a statement

Identifying the Scope of Your Lit. Review

In the early phase of planning your literature review, you will want to identify the scope of your research. Below are a few elements to consider:

• How long will the literature review be?
• How many sources/citations are required?
• Will the literature under review have a publication date requirement? (For example, you will only include sources published between 1990 and 2010.)
• What type of resources will you consult? (e.g. trade journals, peer review journals, books, websites, etc.)
• Will your literature review focus on a theoretical issue, on a topical issue, or on qualitative/quantitative research?

1 Narrowing a Topic

Defining your research question is a process of working from the outside in: you start with the world of all possible topics (or your assigned topic) and narrow down until you have focused your interest enough to be able to state precisely what you want to find out, instead of only what you want to “write about.”

Going through this process can be the hardest part of doing research, but once you have a question that is realistically scoped (not too broad, not too narrow) it will guide the rest of your work.

 The Process of Narrowing a Topic

ACTIVITY: Which Topic is Narrower? 

Now it’s your turn. Practice thinking about narrower topics with these 3 examples. Click the arrow to show the next question.

TIP: Use Some of the 5 W’s to Help Narrow Your Topic to a Searchable Question

Your assignment is to write on the topic of higher education. You decide you want to write about the high cost of tuition, but that is still too broad.

Start by asking some or all of the following questions.

From asking these questions, you might come up with a research question like this:

“How does the high cost of tuition impact the degree completion of mature college students?”

Tips for Creating a Literature Review

➤ When designing a Literature Review for any topic it is useful to establish a narrative for the project. This forces an understanding of  what kind of Review you are conducting. What is a narrative in this context? Try phrasing your topic in terms of a story you are telling . For example if you are researching the impact of mobile diagnostic units on rates of TB in a country in Africa. You might compose your narrative as "if a school child in Peru has been exposed to TB, how much does it affect her possibilities for a healthy life if a mobile diagnostic unit is available in her village?" The pertinent phrase here is how much, because research will concern itself with a comparison of a base line rate of TB cases with the rate where mobile diagnostics have been available.

➤ Highlight how you are going to weight articles you discover in terms of their pertinence to your narrative.

➤ How will you know when you have covered the entire literature on a topic? When you start to get recursive results from your searches.

Once the citations you import from an index in to your citation manager start to cite the articles you have already included in your review, then you have covered the topic.

Click here for  2.1 Step-by-step Instructions (w/ screenshots) on How to Find Review Articles

• Requirements (scope, # of references, nature of the sources, publication style such as APA, etc.) 
• Focus (theories, empirical findings, methodologies, etc.)
• To find keywords for your topic, consult  Indexes  at the end of the books 
• Browse the reference list of an article and chain the citations   
• Consider personal interests   
• Scholarly journals are also called  academic, peer-reviewed, or refereed journals
• Sales & Marketing Management   : a trade magazine
• International Journal of Internet Marketing & Advertising    : a scholarly journal          
• Browse  " Annual Reviews " publications in the field, if available  
• From your department 
• From other institutions   
• CFP List : An academic call for papers database in Humanities and Social Sciences 
• NBER Project on Economic Dimensions of Personalized and Precision Medicine   
• NSF's Interdisciplinary Behavioral and Social Science Research (IBSS)
• Research Topics suggested by UK's ESRC (Economic & Social Research Council) 
• FSU Office of Research Development's Finding Funding page  
• Brainstorm a list of possible topics

After selecting a topic, if your assignment requires a working thesis, try to formulate a preliminary working thesis. This will serve as a roadmap to your search. 

• Tip on writing thesis statement s (from UNC's The Writing Center)

Once you conduct an initial search of the literature, you might want to refine your topic. Two common ways are: 

• Narrow down the topic by adding delimitations or more keywords/concepts
•  For a limited period of time (i.e. the past 10 years of literature only)  
• E.g., Treisman, D. (2007). What have we learned about the causes of corruption from ten years of cross-national empirical research?.  Annu. Rev. Polit. Sci. ,  10 , 211-244.  
• For a specific group only
• E.g., "Adolescent Depression"  -->  "Depression among HIV-affected youth" 
• Adding extra search terms /topics
• E.g., "Voter turnout" --> "Negative campaign and voter turnout " 
• Expand the topic by getting rid of the delimitations or using broader concepts 
• E.g., "Instructional effectiveness of games for teaching grammar"  --> "Effectiveness of games for language teaching"

After refining your topic, revise a working thesis accordingly.

How to structure your literature review (ignore the monotone voice as advice is good)

How to structure and write your literature review

• Chronological, ie. by date of publication or trend
• Methodological
• Use Cooper's taxonomy to explore and determine what elements and categories to incorporate into your review
• Revise and proofread your review to ensure your arguments, supporting evidence and writing is clear and precise

Cronin, P., Ryan, F. & Coughlan, M. (2008). Undertaking a literature review: A step-by-step approach . British Journal of Nursing, 17 (1), pp.38-43.

Different ways to organise a Literature Review

CHRONOLOGICAL (by date): This is one of the most common ways, especially for topics that have been talked about for a long time and have changed over their history. Organise it in stages of how the topic has changed: the first definitions of it, then major time periods of change as researchers talked about it, then how it is thought about today.

BROAD-TO-SPECIFIC : Another approach is to start with a section on the general type of issue you're reviewing, then narrow down to increasingly specific issues in the literature until you reach the articles that are most specifically similar to your research question, thesis statement, hypothesis, or proposal. This can be a good way to introduce a lot of background and related facets of your topic when there is not much directly on your topic but you are tying together many related, broader articles.

MAJOR MODELS or MAJOR THEORIES : When there are multiple models or prominent theories, it is a good idea to outline the theories or models that are applied the most in your articles. That way you can group the articles you read by the theoretical framework that each prefers, to get a good overview of the prominent approaches to your concept.

PROMINENT AUTHORS : If a certain researcher started a field, and there are several famous people who developed it more, a good approach can be grouping the famous author/researchers and what each is known to have said about the topic. You can then organise other authors into groups by which famous authors' ideas they are following. With this organisation it can help to look at the citations your articles list in them, to see if there is one author that appears over and over.

CONTRASTING SCHOOLS OF THOUGHT : If you find a dominant argument comes up in your research, with researchers taking two sides and talking about how the other is wrong, you may want to group your literature review by those schools of thought and contrast the differences in their approaches and ideas.

Ways to structure your Literature Review

Different ways to organise your literature review include:

• Topical order (by main topics or issues, showing relationship to the main problem or topic)
• Chronological order (simplest of all, organise by dates of published literature)
• Problem-cause-solution order
• General to specific order
• Known to unknown order
• Comparison and contrast order
• Specific to general order

Getting Acquainted with the Literature and Identifying Gaps

In addition to the suggestions on this page, you can narrow down your research question by getting a better understanding of the literature in your field and what gaps exist in the research.

Here are some ways to do that:

• Read recent issues of the top scholarly journals in your field. Not sure what those are? Ask your professor/advisor, or you can use tools like Journal Citation Reports (below) to identify top journals by impact factor.
• Read Calls for Papers in your field. Most journals, conferences, and book editors promote requests for proposals for upcoming publications or presentations, which will give you an idea of the scope for what they are looking for and may also present current themes of interest to researchers in your discipline. If you are a member of a professional organization for your area, these organizations usually share those calls to their members as well.
• Identify and read seminal works in your field. Your professors may be able to point you to important works you should know about, and reading these may give you an idea for how you might build on that previous research.
• Talk to your professor/advisor/editor. They might have suggestions for what angle you might take for your literature review.
• Journal Citation Reports This link opens in a new window

What Is a Researchable Topic?

A good literature review begins with a good research question. What makes a good research question? Something answerable by more than a yes or no answer. For example,  climate change  is an okay topic to begin with, but what about it? Ask yourself the who, what, where, when, why, and how questions about your topic.  Climate change  might become how is coastal erosion caused by climate change affecting communities on the coast of Southeast Louisiana ? The more narrow your topic is, the easier it will be to limit your search.

Once you've selected a topic, you can refine it by either expanding or limiting your focus. You could limit your research to a particular time period (perhaps the past 10 years of research on the topic), the group studied (looking at only a particular population). You could expand your research by adding additional concepts (in our example, maybe looking at the effects of both coastal erosion and increased severe weather events) or removing limiters (like getting rid of a time period limit).

If you're finding that refining process challenging, do some background research. The research process is iterative, so every time you read another piece of information, your background knowledge grows and changes, and your research question may shift based on what you've read. We'll go over some ideas for developing background knowledge below.

Finding Example Review Articles

You can find example review articles to serve as a model and introduce you to important pieces of research. You can find review articles in a few ways:

• Search a database, such as Academic Search Complete, for  "literature review" OR review AND  your topic. E.g.  "literature review" OR review AND "Civil War"
• Search the E-Journals tab on the Libraries' homepage for  Annual Review of ... to find annual review journals in your discipline
• Use the Annual Reviews database (below) to browse issues of annual review journals. Note: this is helpful for some disciplines in the sciences and social sciences, but does not include annual reviews for disciplines like the arts, humanities, or business.
• Annual Reviews This link opens in a new window

Finding Dissertations/Theses

For those who are working on a literature review for a dissertation or thesis, it can be helpful to look at the literature reviews of others in your program at LSU or other institutions. Where you can find these depends on factors like the age and institution of the dissertation/thesis. You can find step-by-step instructions for how to search on the guide below.

How to transition from a broad topic to a specific question.

Ask yourself the 5W's in order to break down your topic and make it more specific

Who, What, Where, When, Why?

For Example:

Topic:  mindfulness in the classroom

Who  -  Professors and college students

What - support mental health, behavior, and mood 

Where - College campuses in the Midwest.

When-  Now or in the near future.

Why - To reduce stress in college classrooms.

Becomes: Does teaching mindfulness impact stress levels in the college classroom?

When part of a larger paper, you may need to write a  thesis statement, based on your research question. A thesis statement is the way you convey to your reader the main idea of your paper and the points you will make.

This statement relies on the information you learn in the literature review.

This is often done by making a statement that consists of ____ is ____ because reasons 1,2, and 3. 

For example: Mindfulness is beneficial for classrooms because it has been shown to reduce stress , increase productivity and improve overall mood of students and teachers. 

• Review what a literature review is, and is not 
• Review your assignment and seek clarification from your instructor if needed
• Narrow your topic
• Search and gather  literature resources. 
• Read and analyze  literature resources
• Construct the thesis statement
• Write the literature review and the rest of your paper
• Review appropriate  Citation and Documentation Style  for your assignment and literature review

What is a literature review?

A literature review is an integrated analysis -- not just a summary-- of scholarly writings and other relevant evidence related directly to your research question.  That is, it represents a synthesis of the evidence that provides background information on your topic and shows a association between the evidence and your research question.

A literature review may be a stand alone work or the introduction to a larger research paper, depending on the assignment.  Rely heavily on the guidelines your instructor has given you.

Why is it important?

A literature review is important because it:

• Explains the background of research on a topic.
• Demonstrates why a topic is significant to a subject area.
• Discovers relationships between research studies/ideas.
• Identifies major themes, concepts, and researchers on a topic.
• Identifies critical gaps and points of disagreement.
• Discusses further research questions that logically come out of the previous studies.

APA7 Style resources

APA Style Blog - for those harder to find answers

1. Choose a topic. Define your research question.

Your literature review should be guided by your central research question.  The literature represents background and research developments related to a specific research question, interpreted and analyzed by you in a synthesized way.

• Make sure your research question is not too broad or too narrow.  Is it manageable?
• Begin writing down terms that are related to your question. These will be useful for searches later.
• If you have the opportunity, discuss your topic with your professor and your class mates.

2. Decide on the scope of your review

How many studies do you need to look at? How comprehensive should it be? How many years should it cover? 

• This may depend on your assignment.  How many sources does the assignment require?

3. Select the databases you will use to conduct your searches.

Make a list of the databases you will search.

• Find other databases in the Nursing Information Resources web page
• More on the Medical Library web page
• ... and more on the Yale University Library web page

4. Conduct your searches to find the evidence. Keep track of your searches.

• Use the key words in your question, as well as synonyms for those words, as terms in your search. Use the database tutorials for help.
• Save the searches in the databases. This saves time when you want to redo, or modify, the searches. It is also helpful to use as a guide is the searches are not finding any useful results.
• Review the abstracts of research studies carefully. This will save you time.
• Use the bibliographies and references of research studies you find to locate others.
• Check with your professor, or a subject expert in the field, if you are missing any key works in the field.
• Ask your librarian for help at any time.
• Use a citation manager, such as EndNote as the repository for your citations. See the EndNote tutorials for help.

Review the literature

Some questions to help you analyze the research:

• What was the research question of the study you are reviewing? What were the authors trying to discover?
• Was the research funded by a source that could influence the findings?
• What were the research methodologies? Analyze its literature review, the samples and variables used, the results, and the conclusions.
• Does the research seem to be complete? Could it have been conducted more soundly? What further questions does it raise?
• If there are conflicting studies, why do you think that is?
• How are the authors viewed in the field? Has this study been cited? If so, how has it been analyzed?

Tips: 

• Review the abstracts carefully.  
• Keep careful notes so that you may track your thought processes during the research process.
• Create a matrix of the studies for easy analysis, and synthesis, across all of the studies.

Literature Review

How to search effectively.

• Find examples of literature reviews
• How to write a literature review
• Grey literature

The  Literature searching interactive tutorial  includes self-paced, guided activities to assist you in developing  effective search skills..

1. Identify search words

Analyse your research topic or question.

• What are the main ideas?
• What concepts or theories have you already covered?
• Write down your main ideas, synonyms, related words and phrases.
• If you're looking for specific types of research, use these suggested terms: qualitative, quantitative, methodology, review, survey, test, trend (and more).
• Be aware of UK and US spelling variations. E.g. organisation OR organization, ageing OR aging.
• Interactive Keyword Builder
• Identifying effective keywords

2. Connect your search words

Find results with one or more search words.

Use OR between words that mean the same thing.

E.g.  adolescent  OR  teenager

This search will find results with either (or both) of the search words.

Find results with two search words

Use AND between words which represent the main ideas in the question.

E.g. adolescent AND “physical activity”

This will find results with both of the search words.

Exclude search words

Use NOT to exclude words that you don’t want in your search results.

E.g. (adolescent OR teenager) NOT “young adult”

3. Use search tricks

Search for different word endings.

Truncation *

The asterisk symbol * will help you search for different word endings.

E.g. teen* will find results with the words: teen, teens, teenager, teenagers

Specific truncation symbols will vary. Check the 'Help' section of the database you are searching.

Search for common phrases

Phrase searching “...........”

Double quotation marks help you search for common phrases and make your results more relevant.

E.g. “physical activity” will find results with the words physical activity together as a phrase.

Search for spelling variations within related terms

Wildcards ?

Wildcard symbols allow you to search for spelling variations within the same or related terms.

E.g. wom?n will find results with women OR woman

Specific wild card symbols will vary. Check the 'Help' section of the database you are searching.

Search terms within specific ranges of each other

Proximity  w/#

Proximity searching allows you to specify where your search terms will appear in relation to each other.

E.g.  pain w/10 morphine will search for pain within ten words of morphine

Specific proximity symbols will vary. Check the 'Help' section of the database you are searching.

4. Improve your search results

All library databases are different and you can't always search and refine in the same way. Try to be consistent when transferring your search in the library databases you have chosen.

Narrow and refine your search results by:

• year of publication or date range (for recent or historical research)
• document or source type (e.g. article, review or book)
• subject or keyword (for relevance). Try repeating your search using the 'subject' headings or 'keywords' field to focus your search
• searching in particular fields, i.e. citation and abstract. Explore the available dropdown menus to change the fields to be searched.

When searching, remember to:

Adapt your search and keep trying.

Searching for information is a process and you won't always get it right the first time. Improve your results by changing your search and trying again until you're happy with what you have found.

Keep track of your searches

Keeping track of searches saves time as you can rerun them, store references, and set up regular alerts for new research relevant to your topic.

Most library databases allow you to register with a personal account. Look for a 'log in', 'sign in' or 'register' button to get started.

Getting Started with Research at Shapiro Library

Narrowing down or broadening your topic.

When you need to broaden or narrow down your topic, ask yourself:

Who am I researching?

• Consider age, gender, profession, ethnicity, humans vs. animals vs. corporations, etc.

What am I researching?

• Consider potential causes and effects, trends, statistics, problems, etc.

When? 

What time period am I interested in? 

• Consider when the topic became significant, century vs. specific dates, historical vs. current data, etc.

Where is my research topic taking place? 

• Consider country, state, city, urban vs. rural, environments like prisons vs. college towns, etc.

Why?  

Why does my research matter?

• Consider what makes it important to you, to your colleagues and peers, to your community, to the world, etc.

Narrowing Down Research Topic: Ultimate Guide With Examples

For most students, narrowing down a research topic makes a huge difference between how they carried out the research while in high school and how they should conduct their research projects in college.

Choosing a suitable research topic requires that you work from outside in. Often, you’ll start with a broader topic and narrow it down to a level where you can establish what you’d like to find out rather than only what you’d like to “write about.”

Whether you’ve been given a general topic to investigate, given several problems to study, or you need to come up with your own topic to study, you should ensure that the research problem’s scope underpinning the study isn’t too broad.

A Step-by-Step Example on Narrowing a Research Topic

To narrow down a specific topic, follow these steps:

1. Choose a general topic area.

An example could be employee turnover.

2. Give specific description of the topic area.

Example: turnover in the nursing industry

3. Mention an aspect of the specific topic:

Example: factors that affect turnover among registered nurses

To narrow down a topic’s focus, follow these steps:

4. Note down extra specifics about the topic.

Example: Workplace stress and turnover among registered nurses.

5. Turn the topic into a sentence or statement.

Example: Workplace stress has a significant impact on turnover among registered nurses.

6. Fine-tune your topic’s focus using elements such as time, place, and relationship.

Example: Workplace stress causes increased turnover among registered nurses in Brooklyn.

What’s Too Broad?

College students get tired when an instructor tells them that the topic they chose is too broad. This problem is very common. How do you tell if your topic is too broad?

If you’ve summed up the topic in one or two words, such as education, school cheating, corporal punishment, smoking, or overweight teens, it’s obviously too broad.

If you visit the library and realize you are staring at a whole section of books that you can use as sources for your study topic, then the topic is too broad. A good topic should address a specific problem or question. You should spot four to five books (or even fewer) on a shelf that can effectively address a specific research problem.

If you can’t easily come up with a thesis statement for your research paper, then chances are your topic is too broad.

The Dangers Of Not Narrowing Down

If you don’t do that, you’ll find it challenging to handle the study problem on the time and space provided. You might face a couple of issues if you choose to write on a very broad PhD research topic. The issues include:

Finding tons of sources of information, which makes it difficult to choose what to omit or include, or what’s the most essential.

Finding generic information that makes it tricky to come up with a clear framework for addressing the research problem

Lack of adequate parameters to effectively define the research problem makes it challenging to identify and use correct methods required for its analysis.

You come across information that addresses a wide array of concepts that can’t be included in a single paper. Consequently, you easily get into unnecessary details.

When starting to write a research paper, there’s a common challenge – determining how to narrow down a research topic.

Even if the professor assigns you a specific topic of study, you’ll still be required to narrow it down to some degree. Besides, the professor will find it boring to mark fifty papers talking about the same thing.

That’s why you should narrow your study’s focus early in the writing process. That way, you won’t try to do too much in one research paper.

Tips For Narrowing A Research Topic

Select one lens and use it for viewing a research problem. The other alternative is to focus on just one angle. For example, instead of studying the different factors that cause cancer, study how smoking can cause lung cancer.

Figure out if the initial unit or variable of analysis can be partitioned into smaller components, so you analyze them with more precision. For example, a study on the use of tobacco among teenagers can be narrowed down to chewing tobacco instead of all forms of tobacco use or teenagers in general. A better approach would be to focus on male teenagers in a specific age range and region who chew tobacco.

Methodology

The methods used to gather data can reduce the scope of interpretive analysis required to address your research problem. For example, you can design a single case study to generate data that won’t require an extensive explanation as that of using multiple cases.

In general, analyzing a smaller geographical unit means a narrow topical focus. For example, instead of studying trade relations in Asia, focus on trade relations between China and Singapore as a case study to guide you in explaining problems in that region.

Relationship

Find out how two or more variables or perspectives relate to each other. When you design a study around the correlation of different variables, it helps you to reduce the scope of your analysis. Examples of variables to look out for are:

Cause and effect

Group and individual

Compare and contrast

Contemporary and historical

Problem and solution

Male and female

Opinion and reason

Study periods can be assigned timeframes. Generally, the shorter a study’s time period, the more narrow its focus becomes. For example, instead of studying trade relations between China and Singapore, focus on the trade relations between China and Singapore between 2010 and 2018.

Focus the study topic with regard to a particular class of people, phenomena, or places. For instance, a study of developing better housing near schools may focus on condominiums, universities, or building materials only.

Combination

You can choose at least two of the above tips to narrow down to a specific topic.

Narrowing Down A Research Topic Is Vital – Use Our Advice!

In sum, you can use the broad topic given by your instructor to narrow down, or you can come up with your own topic first and narrow it down (some teachers give this freedom). Either way, you should ensure your narrowed topic is specific and more of a sentence than just a couple of words.

Remember, you want to be able to write a good thesis statement from the topic and proceed to write a paper on it. You can ask for feedback from your friends or instructor to confirm the topic is good and worth writing about. As you can see, it’s easier to write on a specific topic than one that’s too broad.
