Show that you understand the current state of research on your topic.
The length of a research proposal can vary quite a bit. A bachelor’s or master’s thesis proposal can be just a few pages, while proposals for PhD dissertations or research funding are usually much longer and more detailed. Your supervisor can help you determine the best length for your work.
One trick to get started is to think of your proposal’s structure as a shorter version of your thesis or dissertation , only without the results , conclusion and discussion sections.

Writing a research proposal can be quite challenging, but a good starting point could be to look at some examples. We’ve included a few for you below.
Like your dissertation or thesis, the proposal will usually have a title page that includes:
The first part of your proposal is the initial pitch for your project. Make sure it succinctly explains what you want to do and why.
Your introduction should:
To guide your introduction , include information about:
As you get started, it’s important to demonstrate that you’re familiar with the most important research on your topic. A strong literature review shows your reader that your project has a solid foundation in existing knowledge or theory. It also shows that you’re not simply repeating what other people have already done or said, but rather using existing research as a jumping-off point for your own.
In this section, share exactly how your project will contribute to ongoing conversations in the field by:
Following the literature review, restate your main objectives . This brings the focus back to your own project. Next, your research design or methodology section will describe your overall approach, and the practical steps you will take to answer your research questions.

To finish your proposal on a strong note, explore the potential implications of your research for your field. Emphasise again what you aim to contribute and why it matters.
For example, your results might have implications for:
Last but not least, your research proposal must include correct citations for every source you have used, compiled in a reference list . To create citations quickly and easily, you can use our free APA citation generator .
Some institutions or funders require a detailed timeline of the project, asking you to forecast what you will do at each stage and how long it may take. While not always required, be sure to check the requirements of your project.
Here’s an example schedule to help you get started. You can also download a template at the button below.

If you are applying for research funding, chances are you will have to include a detailed budget. This shows your estimates of how much each part of your project will cost.
Make sure to check what type of costs the funding body will agree to cover. For each item, include:
To determine your budget, think about:
Once you’ve decided on your research objectives , you need to explain them in your paper, at the end of your problem statement.
Keep your research objectives clear and concise, and use appropriate verbs to accurately convey the work that you will carry out for each one.
I will compare …
A research aim is a broad statement indicating the general purpose of your research project. It should appear in your introduction at the end of your problem statement , before your research objectives.
Research objectives are more specific than your research aim. They indicate the specific ways you’ll address the overarching aim.
A PhD, which is short for philosophiae doctor (doctor of philosophy in Latin), is the highest university degree that can be obtained. In a PhD, students spend 3–5 years writing a dissertation , which aims to make a significant, original contribution to current knowledge.
A PhD is intended to prepare students for a career as a researcher, whether that be in academia, the public sector, or the private sector.
A master’s is a 1- or 2-year graduate degree that can prepare you for a variety of careers.
All master’s involve graduate-level coursework. Some are research-intensive and intend to prepare students for further study in a PhD; these usually require their students to write a master’s thesis . Others focus on professional training for a specific career.
Critical thinking refers to the ability to evaluate information and to be aware of biases or assumptions, including your own.
Like information literacy , it involves evaluating arguments, identifying and solving problems in an objective and systematic way, and clearly communicating your ideas.

Learn about our Editorial Process
A research proposal systematically and transparently outlines a proposed research project.
The purpose of a research proposal is to demonstrate a project’s viability and the researcher’s preparedness to conduct an academic study. It serves as a roadmap for the researcher.
The process holds value both externally (for accountability purposes and often as a requirement for a grant application) and intrinsic value (for helping the researcher to clarify the mechanics, purpose, and potential signficance of the study).
Key sections of a research proposal include: the title, abstract, introduction, literature review, research design and methods, timeline, budget, outcomes and implications, references, and appendix. Each is briefly explained below.
Watch my Guide: How to Write a Research Proposal
Get your Template for Writing your Research Proposal Here (With AI Prompts!)
Title: The title should present a concise and descriptive statement that clearly conveys the core idea of the research projects. Make it as specific as possible. The reader should immediately be able to grasp the core idea of the intended research project. Often, the title is left too vague and does not help give an understanding of what exactly the study looks at.
Abstract: Abstracts are usually around 250-300 words and provide an overview of what is to follow – including the research problem , objectives, methods, expected outcomes, and significance of the study. Use it as a roadmap and ensure that, if the abstract is the only thing someone reads, they’ll get a good fly-by of what will be discussed in the peice.
Introduction: Introductions are all about contextualization. They often set the background information with a statement of the problem. At the end of the introduction, the reader should understand what the rationale for the study truly is. I like to see the research questions or hypotheses included in the introduction and I like to get a good understanding of what the significance of the research will be. It’s often easiest to write the introduction last
Literature Review: The literature review dives deep into the existing literature on the topic, demosntrating your thorough understanding of the existing literature including themes, strengths, weaknesses, and gaps in the literature. It serves both to demonstrate your knowledge of the field and, to demonstrate how the proposed study will fit alongside the literature on the topic. A good literature review concludes by clearly demonstrating how your research will contribute something new and innovative to the conversation in the literature.
Research Design and Methods: This section needs to clearly demonstrate how the data will be gathered and analyzed in a systematic and academically sound manner. Here, you need to demonstrate that the conclusions of your research will be both valid and reliable. Common points discussed in the research design and methods section include highlighting the research paradigm, methodologies, intended population or sample to be studied, data collection techniques, and data analysis procedures . Toward the end of this section, you are encouraged to also address ethical considerations and limitations of the research process , but also to explain why you chose your research design and how you are mitigating the identified risks and limitations.
Timeline: Provide an outline of the anticipated timeline for the study. Break it down into its various stages (including data collection, data analysis, and report writing). The goal of this section is firstly to establish a reasonable breakdown of steps for you to follow and secondly to demonstrate to the assessors that your project is practicable and feasible.
Budget: Estimate the costs associated with the research project and include evidence for your estimations. Typical costs include staffing costs, equipment, travel, and data collection tools. When applying for a scholarship, the budget should demonstrate that you are being responsible with your expensive and that your funding application is reasonable.
Expected Outcomes and Implications: A discussion of the anticipated findings or results of the research, as well as the potential contributions to the existing knowledge, theory, or practice in the field. This section should also address the potential impact of the research on relevant stakeholders and any broader implications for policy or practice.
References: A complete list of all the sources cited in the research proposal, formatted according to the required citation style. This demonstrates the researcher’s familiarity with the relevant literature and ensures proper attribution of ideas and information.
Appendices (if applicable): Any additional materials, such as questionnaires, interview guides, or consent forms, that provide further information or support for the research proposal. These materials should be included as appendices at the end of the document.
Research proposals often extend anywhere between 2,000 and 15,000 words in length. The following snippets are samples designed to briefly demonstrate what might be discussed in each section.

Consider this hypothetical education research proposal:
The Impact of Game-Based Learning on Student Engagement and Academic Performance in Middle School Mathematics
Abstract: The proposed study will explore multiplayer game-based learning techniques in middle school mathematics curricula and their effects on student engagement. The study aims to contribute to the current literature on game-based learning by examining the effects of multiplayer gaming in learning.
Introduction: Digital game-based learning has long been shunned within mathematics education for fears that it may distract students or lower the academic integrity of the classrooms. However, there is emerging evidence that digital games in math have emerging benefits not only for engagement but also academic skill development. Contributing to this discourse, this study seeks to explore the potential benefits of multiplayer digital game-based learning by examining its impact on middle school students’ engagement and academic performance in a mathematics class.
Literature Review: The literature review has identified gaps in the current knowledge, namely, while game-based learning has been extensively explored, the role of multiplayer games in supporting learning has not been studied.
Research Design and Methods: This study will employ a mixed-methods research design based upon action research in the classroom. A quasi-experimental pre-test/post-test control group design will first be used to compare the academic performance and engagement of middle school students exposed to game-based learning techniques with those in a control group receiving instruction without the aid of technology. Students will also be observed and interviewed in regard to the effect of communication and collaboration during gameplay on their learning.
Timeline: The study will take place across the second term of the school year with a pre-test taking place on the first day of the term and the post-test taking place on Wednesday in Week 10.
Budget: The key budgetary requirements will be the technologies required, including the subscription cost for the identified games and computers.
Expected Outcomes and Implications: It is expected that the findings will contribute to the current literature on game-based learning and inform educational practices, providing educators and policymakers with insights into how to better support student achievement in mathematics.

Consider this hypothetical psychology research proposal:
The Effects of Mindfulness-Based Interventions on Stress Reduction in College Students
Abstract: This research proposal examines the impact of mindfulness-based interventions on stress reduction among college students, using a pre-test/post-test experimental design with both quantitative and qualitative data collection methods .
Introduction: College students face heightened stress levels during exam weeks. This can affect both mental health and test performance. This study explores the potential benefits of mindfulness-based interventions such as meditation as a way to mediate stress levels in the weeks leading up to exam time.
Literature Review: Existing research on mindfulness-based meditation has shown the ability for mindfulness to increase metacognition, decrease anxiety levels, and decrease stress. Existing literature has looked at workplace, high school and general college-level applications. This study will contribute to the corpus of literature by exploring the effects of mindfulness directly in the context of exam weeks.
Research Design and Methods: Participants ( n= 234 ) will be randomly assigned to either an experimental group, receiving 5 days per week of 10-minute mindfulness-based interventions, or a control group, receiving no intervention. Data will be collected through self-report questionnaires, measuring stress levels, semi-structured interviews exploring participants’ experiences, and students’ test scores.
Timeline: The study will begin three weeks before the students’ exam week and conclude after each student’s final exam. Data collection will occur at the beginning (pre-test of self-reported stress levels) and end (post-test) of the three weeks.
Expected Outcomes and Implications: The study aims to provide evidence supporting the effectiveness of mindfulness-based interventions in reducing stress among college students in the lead up to exams, with potential implications for mental health support and stress management programs on college campuses.
Consider this hypothetical sociology research proposal:
The Impact of Social Media Usage on Interpersonal Relationships among Young Adults
Abstract: This research proposal investigates the effects of social media usage on interpersonal relationships among young adults, using a longitudinal mixed-methods approach with ongoing semi-structured interviews to collect qualitative data.
Introduction: Social media platforms have become a key medium for the development of interpersonal relationships, particularly for young adults. This study examines the potential positive and negative effects of social media usage on young adults’ relationships and development over time.
Literature Review: A preliminary review of relevant literature has demonstrated that social media usage is central to development of a personal identity and relationships with others with similar subcultural interests. However, it has also been accompanied by data on mental health deline and deteriorating off-screen relationships. The literature is to-date lacking important longitudinal data on these topics.
Research Design and Methods: Participants ( n = 454 ) will be young adults aged 18-24. Ongoing self-report surveys will assess participants’ social media usage, relationship satisfaction, and communication patterns. A subset of participants will be selected for longitudinal in-depth interviews starting at age 18 and continuing for 5 years.
Timeline: The study will be conducted over a period of five years, including recruitment, data collection, analysis, and report writing.
Expected Outcomes and Implications: This study aims to provide insights into the complex relationship between social media usage and interpersonal relationships among young adults, potentially informing social policies and mental health support related to social media use.
Consider this hypothetical nursing research proposal:
The Influence of Nurse-Patient Communication on Patient Satisfaction and Health Outcomes following Emergency Cesarians
Abstract: This research will examines the impact of effective nurse-patient communication on patient satisfaction and health outcomes for women following c-sections, utilizing a mixed-methods approach with patient surveys and semi-structured interviews.
Introduction: It has long been known that effective communication between nurses and patients is crucial for quality care. However, additional complications arise following emergency c-sections due to the interaction between new mother’s changing roles and recovery from surgery.
Literature Review: A review of the literature demonstrates the importance of nurse-patient communication, its impact on patient satisfaction, and potential links to health outcomes. However, communication between nurses and new mothers is less examined, and the specific experiences of those who have given birth via emergency c-section are to date unexamined.
Research Design and Methods: Participants will be patients in a hospital setting who have recently had an emergency c-section. A self-report survey will assess their satisfaction with nurse-patient communication and perceived health outcomes. A subset of participants will be selected for in-depth interviews to explore their experiences and perceptions of the communication with their nurses.
Timeline: The study will be conducted over a period of six months, including rolling recruitment, data collection, analysis, and report writing within the hospital.
Expected Outcomes and Implications: This study aims to provide evidence for the significance of nurse-patient communication in supporting new mothers who have had an emergency c-section. Recommendations will be presented for supporting nurses and midwives in improving outcomes for new mothers who had complications during birth.
Consider this hypothetical social work research proposal:
The Role of a Family-Centered Intervention in Preventing Homelessness Among At-Risk Youthin a working-class town in Northern England
Abstract: This research proposal investigates the effectiveness of a family-centered intervention provided by a local council area in preventing homelessness among at-risk youth. This case study will use a mixed-methods approach with program evaluation data and semi-structured interviews to collect quantitative and qualitative data .
Introduction: Homelessness among youth remains a significant social issue. This study aims to assess the effectiveness of family-centered interventions in addressing this problem and identify factors that contribute to successful prevention strategies.
Literature Review: A review of the literature has demonstrated several key factors contributing to youth homelessness including lack of parental support, lack of social support, and low levels of family involvement. It also demonstrates the important role of family-centered interventions in addressing this issue. Drawing on current evidence, this study explores the effectiveness of one such intervention in preventing homelessness among at-risk youth in a working-class town in Northern England.
Research Design and Methods: The study will evaluate a new family-centered intervention program targeting at-risk youth and their families. Quantitative data on program outcomes, including housing stability and family functioning, will be collected through program records and evaluation reports. Semi-structured interviews with program staff, participants, and relevant stakeholders will provide qualitative insights into the factors contributing to program success or failure.
Timeline: The study will be conducted over a period of six months, including recruitment, data collection, analysis, and report writing.
Budget: Expenses include access to program evaluation data, interview materials, data analysis software, and any related travel costs for in-person interviews.
Expected Outcomes and Implications: This study aims to provide evidence for the effectiveness of family-centered interventions in preventing youth homelessness, potentially informing the expansion of or necessary changes to social work practices in Northern England.

Research proposal is a document that outlines a proposed research project . It is typically written by researchers, scholars, or students who intend to conduct research to address a specific research question or problem.
Research proposals can vary depending on the nature of the research project and the specific requirements of the funding agency, academic institution, or research program. Here are some common types of research proposals:
This is the most common type of research proposal, which is prepared by students, scholars, or researchers to seek approval and funding for an academic research project. It includes all the essential components mentioned earlier, such as the introduction, literature review , methodology , and expected outcomes.
A grant proposal is specifically designed to secure funding from external sources, such as government agencies, foundations, or private organizations. It typically includes additional sections, such as a detailed budget, project timeline, evaluation plan, and a description of the project’s alignment with the funding agency’s priorities and objectives.
Students pursuing a master’s or doctoral degree often need to submit a proposal outlining their intended research for their dissertation or thesis. These proposals are usually more extensive and comprehensive, including an in-depth literature review, theoretical framework, research questions or hypotheses, and a detailed methodology.
This type of proposal is often prepared by researchers or research teams within an organization or institution. It outlines a specific research project that aims to address a particular problem, explore a specific area of interest, or provide insights for decision-making. Research project proposals may include sections on project management, collaboration, and dissemination of results.
Researchers or scholars applying for research fellowships may be required to submit a proposal outlining their proposed research project. These proposals often emphasize the novelty and significance of the research and its alignment with the goals and objectives of the fellowship program.
In cases where researchers from multiple institutions or disciplines collaborate on a research project, a collaborative research proposal is prepared. This proposal highlights the objectives, responsibilities, and contributions of each collaborator, as well as the overall research plan and coordination mechanisms.
A research proposal typically follows a standard outline that helps structure the document and ensure all essential components are included. While the specific headings and subheadings may vary slightly depending on the requirements of your institution or funding agency, the following outline provides a general structure for a research proposal:

This study will adopt a mixed-methods approach, combining quantitative surveys and qualitative interviews. The quantitative phase will involve administering standardized questionnaires to a representative sample of adolescents to assess their social media use, mental health indicators, and perceived social support. The qualitative phase will include in-depth interviews with a subset of participants to explore their experiences, motivations, and perceptions related to social media use.
3.2 Data Collection Methods:
Quantitative data will be collected through an online survey distributed to schools in the target region. The survey will include validated scales to measure social media use, mental health outcomes, and perceived social support. Qualitative data will be collected through semi-structured interviews with a purposive sample of participants. The interviews will be audio-recorded and transcribed for thematic analysis.
3.3 Data Analysis:
Quantitative data will be analyzed using descriptive statistics and regression analysis to examine the relationships between variables. Qualitative data will be analyzed thematically to identify common themes and patterns within participants’ narratives. Integration of quantitative and qualitative findings will provide a comprehensive understanding of the research questions.
4. Timeline
The research project will be conducted over a period of 12 months, divided into specific phases, including literature review, study design, data collection, analysis, and report writing. A detailed timeline outlining the key milestones and activities is provided in Appendix A.
5. Expected Outcomes and Significance
This study aims to contribute to the existing literature on the impact of social media on adolescent well-being by employing a mixed-methods approach. The findings will inform the development of evidence-based interventions and guidelines to promote healthy social media use among adolescents. This research has the potential to benefit adolescents, parents, educators, and policymakers by providing insights into the complex relationship between social media and well-being and offering strategies for fostering positive online experiences.
6. Resources
The resources required for this research include access to a representative sample of adolescents, research assistants for data collection, statistical software for data analysis, and funding to cover survey administration and participant incentives. Ethical considerations will be taken into account, ensuring participant confidentiality and obtaining informed consent.
7. References
Writing a research proposal can be a complex task, but with proper guidance and organization, you can create a compelling and well-structured proposal. Here’s a step-by-step guide to help you through the process:
The length of a research proposal can vary depending on the specific guidelines provided by your institution or funding agency. However, research proposals typically range from 1,500 to 3,000 words, excluding references and any additional supporting documents.
The purpose of a research proposal is to outline and communicate your research project to others, such as academic institutions, funding agencies, or potential collaborators. It serves several important purposes:
The research proposal holds significant importance in the research process. Here are some key reasons why research proposals are important:
The timing of when to write a research proposal can vary depending on the specific requirements and circumstances. However, here are a few common situations when it is appropriate to write a research proposal:
Researcher, Academic Writer, Web developer
Kits: proposal kit, proposal kit.
These resources are for doctoral students who are at the proposal stage and working on their official proposal documents.
Working on the proposal means that students have a solid topic approved by their committee and can move on to developing the details of their study. This kit focuses on writing the introduction, reviewing the literature, and proposing research design and method for the study. All Walden proposals, whether from professional doctorate degrees or PhD degrees, cover three main areas: introduction to the study, literature review, and discussion of the research design and method.
Students in different programs will see variations in the required number of chapters or sections in the proposal. To begin writing, students should first download the appropriate template for their program, the appropriate checklist and/or rubric, and any other documents that programs have published for guidance.
A student’s committee chairperson, second committee member, and the URR oversee the doctoral process, directing content development and assuring the capstone meets program guidelines.
In addition, the Doctoral Capstone Resources website includes all of the capstone support services provided by the university in one convenient place.
This page can serve as a starting point once a doctoral student has an approved prospectus (or premise, for DNP students) and has begun writing the proposal. These tips and links focus on writing three main areas of the document: introduction, literature review, and research design and method discussion.
The following pages in this proposal kit cover three broad questions students should ask when they begin the proposal, and the final page provides links to resources across the university.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .
There are five key steps to writing a literature review:
A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

What is the purpose of a literature review, examples of literature reviews, step 1 – search for relevant literature, step 2 – evaluate and select sources, step 3 – identify themes, debates, and gaps, step 4 – outline your literature review’s structure, step 5 – write your literature review, free lecture slides, other interesting articles, frequently asked questions, introduction.
When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:
Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.
Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.
You can also check out our templates with literature review examples and sample outlines at the links below.

Before you begin searching for literature, you need a clearly defined topic .
If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .
Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.
Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:
You can also use boolean operators to help narrow down your search.
Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.
You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.
For each publication, ask yourself:
Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.
You can use our template to summarize and evaluate sources you’re thinking about using. Click on either button below to download.
As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.
It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.
Professional editors proofread and edit your paper by focusing on:
See an example
To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:
This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.
There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).
The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.
Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.
If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.
For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.
If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:
A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.
You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.
Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.
The introduction should clearly establish the focus and purpose of the literature review.
Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.
As you write, you can follow these tips:
In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.
When you’ve finished writing and revising your literature review, don’t forget to proofread thoroughly before submitting. Not a language expert? Check out Scribbr’s professional proofreading services !

Statistics
Research bias
A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .
It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.
There are several reasons to conduct a literature review at the beginning of a research project:
Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.
The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .
A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other academic texts , with an introduction , a main body, and a conclusion .
An annotated bibliography is a list of source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a paper .

Research proposal template faqs, what types of research proposals can this template be used for.
The proposal template follows the standard format for academic research projects, which means it will be suitable for the vast majority of dissertations and theses (especially those within the sciences), whether they are qualitative or quantitative in terms of design.
Keep in mind that the exact requirements for the introduction chapter/section will vary between universities and degree programs. These are typically minor, but it’s always a good idea to double-check your university’s requirements before you finalise your structure.
This template can be used for a research project at any level of study. Doctoral-level projects typically require the research proposal to be more extensive/comprehensive, but the structure will typically remain the same.
The length of a research proposal varies by institution and subject, but as a ballpark, it’s usually between 1,500 and 3,000 words.
To be safe, it’s best to check with your university if they have any preferences or requirements in terms of minimum and maximum word count for the research propsal.
You don’t need to go into the fine details of your methodology, but this section should be detailed enough to demonstrate that your research approach is feasible and will address your research questions effectively. Be sure to include your intended methods for data collection and analysis.
Generally, yes. This can strengthen your proposal by demonstrating the feasibility of your research. However, make sure that your pilot study is approved by your university before collecting any data.

Peritoneal dialysis (PD)-associated peritonitis is a serious complication that can lead to PD discontinuation and mortality. Tsukamurella species are uncommon opportunistic pathogens that can cause peritonitis, often necessitating catheter removal.
A 46-year-old woman with a 1.5-year history of PD presented with fever and lower abdominal pain, along with cloudy peritoneal effluent showing an elevated cell count. Empiric antibiotic therapy with ciprofloxacin, cefazolin, and ceftazidime was started for PD-associated peritonitis. The peritoneal effluent culture yielded a gram-positive rod with weak acid-fast staining. A rebound in the cell count necessitated a switch of antibiotics to meropenem and vancomycin. This led to improvement, and the treatment was switched to oral levofloxacin on day 30 and the patient was discharged on day 35. Subsequently, 16S rRNA gene sequencing confirmed the isolate as Tsukamurella inchonensis .
This case highlights the challenges in identifying and treating Tsukamurella peritonitis. Successful treatment without catheter removal in this case suggests that early detection and appropriate antibiotics may enable catheter salvage in this rare infection. However, further research is needed to establish optimal treatment strategies.
Tsukamurella species are aerobic, gram-positive, weakly acid-fast bacilli found in various environmental sources and are increasingly recognized as opportunistic pathogens in humans [ 1 , 2 ]. They can cause a wide range of infections, including pulmonary [ 3 , 4 ], cutaneous [ 5 ], ocular [ 6 ], bloodstream [ 7 , 8 ], central nervous system [ 9 ], and peritoneal infections [ 10 ]. However, accurate identification of these species remains challenging in many clinical microbiology laboratories due to phenotypic and biochemical similarities to other actinomycetes, such as Corynebacterium , Rhodococcus , Nocardia , and non-tuberculous mycobacteria [ 1 ].
One of the most significant complications of peritoneal dialysis (PD) is PD-associated peritonitis, which is a leading cause of PD discontinuation and mortality [ 11 ]. Although prompt empiric antibiotic treatment with broad-spectrum coverage of both gram-positive and gram-negative organisms is crucial, the emergence of less common and drug-resistant pathogens presents an obstacle to successful treatment. Reports of PD-associated peritonitis caused by Tsukamurella spp. are limited, and catheter removal is frequently required for resolution [ 10 , 12 ]. Recent advances in molecular diagnostic methods, particularly matrix-assisted desorption ionization time-of-flight mass spectrometry (MALDI–TOF MS) and 16S rRNA gene sequencing, have significantly improved the identification of Tsukamurella infections.
We report a rare case of PD-associated peritonitis caused by Tsukamurella inchonensis that was successfully treated without catheter removal, highlighting the potential for catheter salvage treatment strategies.
A 46-year-old Japanese woman with a 1.5-year history of automated PD due to autosomal dominant polycystic kidney disease presented with a 3-day history of fever and lower abdominal pain. She had no prior history of PD-associated peritonitis. She had body temperature of 38.9℃, blood pressure of 124/94 mmHg, and heart rate of 131 beats per minute. The PD effluent was cloudy with a cell count of 1000 cells/μL. There was no sign of exit-site infection, history of PD tube troubles, or touch contamination. She was a homemaker and did PD exchange manually without use of a PD connection assist device. She had no pets or hobbies such as gardening. She was admitted with the diagnosis of PD-associated peritonitis. Laboratory findings on admission are presented in Table 1 . After collection of blood, urine, and peritoneal effluent culture samples, she was started on oral ciprofloxacin (CPFX), intraperitoneal (IP) cefazolin (CEZ), and IP ceftazidime (CAZ) daily. The IP antibiotics were administered continuously (every 6 h). The blood and urine cultures were all negative. The aerobic culture bottle of the peritoneal effluent was positive, and gram-positive rod bacteria with weak acid-fast staining were isolated (Fig. 1 a, b). The bacterial isolate could not be identified by MALDI–TOF MS (Bruker MALDI Biotyper®). Our facility was not able to identify the species, but we suspected Tsukamurella spp. due to its yellowish cream-colored colonies and its gram-staining and other staining characteristics (Fig. 1 c–e). We sent the specimen to the Medical Mycology Research Center of Chiba University for molecular analysis. The peritoneal effluent cell count initially decreased after treatment initiation. However, on day 11, a rebound in the cell count to 2770/μL prompted discontinuation of oral CPFX and IP CEZ, and addition of intravenous (IV) meropenem and IP vancomycin. This treatment modification resulted in a decrease in cell count to 70/μL by day 21. By day 30, the count remained consistently below 10/μL, allowing for a switch to oral levofloxacin (LVFX). On day 34, 16S rRNA gene sequencing identified the bacterial isolate as Tsukamurella inchonensis (antibiogram in Table 2 ) [ 10 , 13 , 14 ]. The following day, the patient was discharged with a 1-week prescription of LVFX.

Two months later, the patient developed peritonitis caused by Micrococcus luteus and Moraxella osloensis , which resolved with a 3-week course of antibiotics. Although this episode was unrelated to the prior Tsukamurella infection, its occurrence within 2 months of discharge, coupled with the involvement of environmental bacteria, highlighted the need for improved hygiene practices, particularly in areas prone to bacterial growth, such as the kitchen and bathroom. Therefore, although we did not perform environmental culturing, we recommended improving the patient’s home environment, including the bathroom and shower, and thoroughly wiping off any water droplets that may have adhered to the catheter after bathing. There have been no signs of peritonitis for 6 months since then.
Here, we presented a rare case of PD-associated peritonitis caused by Tsukamurella inchonensis , an emerging opportunistic pathogen. To our knowledge, only a few cases of PD-associated peritonitis due to Tsukamurella have been reported. Although our MALDI–TOF MS analysis of the bacterial isolate failed to provide definitive identification, the isolate’s colony morphology and Gram-staining characteristics suggested the possibility of Tsukamurella infection. This prompted further analyses such as 16S rRNA gene sequencing at another institution because of the lack of specialized equipment for Tsukamurella identification at our facility. Tsukamurella colonies are typically small and dry, with convex elevation, and appear white, cream-colored, or orange [ 1 ]. Only peritoneal effluent culture collected in an aerobic bottle yielded positive results, and the bacterial isolate from this case displayed slow growth, forming small, dry, round, yellowish cream-colored colonies.
According to an in vitro study, Tsukamurella spp. are susceptible to quinolones, trimethoprim/sulfamethoxazole, amikacin, minocycline, linezolid, and tigecycline [ 15 ]. In that study, Tsukamurella isolates were also susceptible to the third- and fourth-generation cephalosporins. Cases of PD-associated peritonitis caused by Tsukamurella spp. are limited, and the optimal management strategy has not yet been determined (Table 3 ) [ 10 , 12 , 13 , 14 ]. Caution may be needed regarding the use of quinolone since the mechanism conferring quinolone resistance in Tsukamurella tyrosinosolvens has been reported [ 15 ], which might be one of the reasons for the difficulty we encountered using CPFX to treat Tsukamurella inchonensis . Another reason was the discrepancy between the isolate’s specific antibiogram, which showed “intermediate” susceptibility against CPFX, and our facility’s standard antibiogram, which indicated it was “susceptible.” This discrepancy could be due to the lack of species-specific data for Tsukamurella in our standard antibiogram.
For treatment of catheter-related bloodstream infections caused by Tsukamurella spp., the combination of catheter removal and appropriate antibiotic treatment is considered essential [ 8 , 15 ]. In some previous reports, successful treatment of Tsukamurella PD-associated peritonitis required catheter removal [ 10 , 12 , 13 ]. However, a case from China [ 14 ] and our case demonstrated successful treatment without catheter removal. These reports are summarized in Table 3 . Although we were unable to identify the route of infection, PD connection troubles [ 13 ] and diarrhea [ 14 ] prior to peritonitis have been reported as infection routes. The necessary treatment duration for Tsukamurella PD-associated peritonitis remains unclear. The case report from China described an 18-day treatment course [ 14 ]. Our case required 42 days of treatment including the duration of oral antibiotics administered after discharge. Also, repeat peritonitis caused by Tsukamurella has not been reported. Treatment recommendations for Gordonia peritonitis, a genus phenotypically similar to Tsukamurella , suggest at least 3 weeks of carbapenem–aminoglycoside combination therapy [ 16 ]. While evidence supporting successful treatment of Tsukamurella peritonitis without catheter removal is limited, our case demonstrates the potential for successful treatment with an antimicrobial therapy course exceeding 3 weeks, with subsequent close follow-up. Accurate identification of Tsukamurella can be achieved through newer molecular biological techniques, thus contributing to the appropriate selection of definitive therapy for infections caused by Tsukamurella [ 17 ]. Prompt therapy and understanding of the clinical, microbiological, and molecular characteristics of Tsukamurella spp. might prevent catheter removal in PD-associated peritonitis caused by these organisms.
Our experience with PD-associated peritonitis caused by Tsukamurella inchonensis suggests the potential for successful treatment without catheter removal. Accurate identification of Tsukamurella might contribute to the selection of appropriate therapy and infectious resolution.
