How to Write a Proposed Intervention Research Paper

Writing a proposed intervention research paper is a critical step in the research process. It outlines your plan for conducting a study that aims to address a specific problem or issue through a carefully designed intervention.

This guide will walk you through the essential components of a proposed intervention research paper, providing detailed explanations and examples to help you craft a comprehensive and compelling proposal.


The introduction section sets the stage for your research paper and captures the reader’s attention. It should provide a clear overview of the topic you’ll be exploring and the significance of your proposed intervention.

Background Information

Start by providing relevant background information on the problem or issue you’ll be addressing. Explain the scope and magnitude of the problem, and how it affects the target population. Use statistics, real-life examples, or case studies to illustrate the significance of the problem and the need for intervention.

Example: “Childhood obesity is a growing public health concern, with approximately 19% of children aged 2-19 years in the United States being obese (Centers for Disease Control and Prevention, 2022). Obesity in children can lead to various physical and mental health issues, including type 2 diabetes, cardiovascular problems, and low self-esteem.”

Purpose Statement

Clearly state the purpose of your proposed intervention research. This should be a concise statement that outlines the main goal of your study and the specific problem or issue you aim to address.

Example: “The purpose of this proposed intervention is to design and evaluate a school-based nutrition education program aimed at promoting healthy eating habits and reducing the prevalence of childhood obesity among elementary school students.”

Research Questions or Hypotheses

Depending on the nature of your research, you’ll either present research questions or hypotheses. Research questions are open-ended inquiries that guide your study, while hypotheses are testable statements that predict the outcome of your research.

Example (Research Questions):

  1. Does the proposed nutrition education program effectively improve students’ knowledge about healthy eating?
  2. To what extent does the intervention influence students’ dietary choices and behaviors?
  3. How do different factors (e.g., gender, socioeconomic status) affect the effectiveness of the intervention?

Example (Hypotheses): H1: Students who participate in the nutrition education program will demonstrate a significant increase in their knowledge of healthy eating compared to those in the control group. H2: Students who participate in the nutrition education program will report higher consumption of fruits and vegetables and lower consumption of unhealthy snacks compared to those in the control group.

Literature Review

The literature review section demonstrates your understanding of the existing body of knowledge related to your topic. It should be comprehensive and critically analyze relevant studies, theories, and models.

Theoretical Framework

Discuss the theoretical framework that underpins your proposed intervention. Explain the key concepts, theories, and models that inform your approach, and how they contribute to the development of your intervention strategy.

Example: “The proposed intervention is grounded in the Social Cognitive Theory (Bandura, 1986), which emphasizes the reciprocal interaction between personal factors, behavioral patterns, and environmental influences. This theory suggests that providing students with knowledge and skills, as well as creating a supportive environment, can positively influence their dietary behaviors.”

Previous Research

Provide an overview of previous research related to your topic. Highlight the strengths and limitations of existing studies, and explain how your proposed intervention addresses gaps or builds upon existing knowledge. Critically analyze the methodologies, findings, and implications of relevant studies, and discuss how they inform your proposed intervention.

Example: “Several school-based nutrition education programs have been implemented and evaluated, with mixed results. Smith et al. (2018) found that their program effectively increased students’ knowledge about healthy eating but did not significantly impact their dietary behaviors. On the other hand, Johnson and colleagues (2020) reported positive changes in both knowledge and behaviors among students who participated in their intervention. However, these studies focused on middle school students, and there is a need for interventions targeting younger age groups.”


The methodology section outlines the specific steps you’ll take to conduct your research. It should be detailed and clear, allowing others to replicate your study if necessary.

Research Design

Describe the research design you’ll be using, such as experimental, quasi-experimental, or qualitative. Explain why this design is appropriate for your study and how it aligns with your research questions or hypotheses.

Example: “This study will employ a quasi-experimental design with a non-equivalent control group. Two elementary schools will be selected, with one school receiving the nutrition education program (intervention group) and the other serving as the control group. This design allows for the comparison of outcomes between the two groups while accounting for potential confounding variables.”

Participants and Sampling

Describe the target population for your intervention and how you’ll select participants. Explain your sampling methods (e.g., random sampling, convenience sampling) and criteria for inclusion or exclusion. Provide details on the sample size calculation and justify the chosen sample size based on statistical power considerations or previous similar studies.

Example: “The target population for this study is elementary school students in grades 3-5 (ages 8-11) in the city of [X]. A convenience sampling method will be used to select two elementary schools based on their willingness to participate and their demographic similarities. All students in the selected grades at the intervention school will be invited to participate, while students in the same grades at the control school will serve as the comparison group. Based on a power analysis, a minimum sample size of 200 students (100 per group) is required to detect a medium effect size with a power of 0.8 and an alpha level of 0.05.”

Intervention Description

Provide a detailed description of the proposed intervention. Explain the specific components, activities, and procedures involved. Use examples or visual aids (e.g., diagrams, flowcharts) to clarify the intervention, if necessary. Discuss the theoretical underpinnings and evidence-based strategies that inform the design of your intervention.

Example: “The proposed nutrition education program will consist of eight weekly sessions, each lasting 60 minutes. The sessions will be conducted during regular school hours and will be led by trained nutritionists and health educators. The program will incorporate interactive activities, multimedia presentations, hands-on cooking demonstrations, and taste tests to engage students and reinforce learning.

The sessions will cover topics such as the importance of a balanced diet, reading nutrition labels, portion control, identifying healthy snack options, and strategies for making healthy food choices. Each session will include a combination of educational content, group discussions, and practical activities to reinforce the concepts learned.

The program will also involve parental engagement through newsletters, online resources, and a family cooking workshop to encourage healthy eating habits at home. Additionally, the school cafeteria will collaborate with the program by offering healthier menu options and promoting the consumption of fruits and vegetables during lunchtime.”

Data Collection

Outline the methods you’ll use to collect data, such as surveys, interviews, observations, or standardized assessments. Describe the instruments or tools you’ll use and their reliability and validity. Explain how the data collection methods align with your research questions or hypotheses.

Example: “Data will be collected using a combination of quantitative and qualitative methods. Students’ knowledge about healthy eating will be assessed using a validated nutrition knowledge questionnaire (Jones et al., 2015) administered before and after the intervention. Dietary intake and behaviors will be measured through a self-reported food frequency questionnaire (FFQ) and a 24-hour dietary recall interview conducted at baseline and post-intervention.

Additionally, focus group discussions with a subset of students from the intervention group will be conducted to gather qualitative data on their experiences, perceptions, and feedback regarding the nutrition education program. Observational data on students’ lunchtime eating behaviors and food choices will also be collected by trained researchers.”

Data Analysis

Explain how you’ll analyze the data collected from your study. Specify the statistical tests or analytical methods you’ll use and how they align with your research questions or hypotheses. Discuss any potential limitations or challenges in data analysis and how you’ll address them.

Example: “Quantitative data from the surveys and questionnaires will be analyzed using appropriate statistical software (e.g., SPSS, R). Descriptive statistics (means, standard deviations, frequencies) will be calculated for demographic variables and outcome measures. Inferential statistics, such as t-tests and analysis of variance (ANOVA), will be used to compare the intervention and control groups on knowledge, dietary intake, and behavior changes.

For the qualitative data from focus group discussions, a thematic analysis approach will be employed. Transcripts will be coded and analyzed to identify recurring themes and patterns related to students’ experiences, perceptions, and suggestions for program improvement.

Potential limitations include self-report bias in dietary intake measures and the possibility of non-response or attrition during the study. To address these limitations, multiple data collection methods will be utilized, and appropriate statistical techniques (e.g., intent-to-treat analysis) will be employed to handle missing data.”

Ethical Considerations

Address any ethical issues or concerns related to your proposed intervention research. Discuss how you’ll protect participants’ rights, maintain confidentiality, and address potential risks or benefits.

Example: “Ethical considerations are of utmost importance in this study, as it involves minors (children) as participants. The research protocol will be submitted to the Institutional Review Board (IRB) for approval to ensure adherence to ethical principles and guidelines.

Informed consent will be obtained from parents/guardians before enrolling their children in the study. The consent form will clearly explain the purpose, procedures, potential risks and benefits, and the voluntary nature of participation. Children will also be asked to provide their assent to participate.

Confidentiality of participants’ data will be maintained throughout the study. All collected data will be de-identified and stored securely, with access limited to the research team members. Participants will be assigned unique codes to protect their identities.

While the proposed intervention is educational and poses minimal risk, potential risks may include discomfort or anxiety during data collection procedures. Trained personnel will be present to address any concerns or distress experienced by participants. Additionally, participants will be informed of their right to withdraw from the study at any time without consequence.

Potential benefits of the study include increased knowledge and awareness about healthy eating habits, improved dietary choices, and the promotion of overall well-being among participating students. The findings may also contribute to the development of effective school-based nutrition education programs, benefiting a broader population of children.”

Significance and Implications

Explain the potential significance and implications of your proposed intervention research. Discuss how your findings could contribute to the existing body of knowledge, inform practice, or influence policy. Highlight the potential impact on the target population and relevant stakeholders.

Example: “The proposed intervention research has the potential to make significant contributions to the field of nutrition education and childhood obesity prevention. By evaluating the effectiveness of a comprehensive school-based program, this study can provide valuable insights into evidence-based strategies for promoting healthy eating behaviors among elementary school students.

If the intervention is found to be effective, the program can be replicated and implemented in other schools or districts, potentially reaching a larger population of children and contributing to the overall efforts to combat childhood obesity. The findings may also inform school policies and practices related to nutrition education, cafeteria menus, and the promotion of healthy eating environments.

Furthermore, the study can contribute to the existing body of knowledge by identifying factors that influence the success or failure of nutrition education interventions, such as age, gender, socioeconomic status, or cultural backgrounds. This understanding can guide the development of tailored and culturally responsive interventions to address the diverse needs of different populations.

Ultimately, the successful implementation of the proposed intervention can have far-reaching implications for children’s health and well-being. By promoting healthy eating habits from an early age, the intervention may contribute to the prevention of obesity-related health issues, such as type 2 diabetes, cardiovascular diseases, and mental health problems. This, in turn, can have long-term benefits for individual well-being, healthcare costs, and societal productivity.”


Summarize the key points of your proposed intervention research paper. Reiterate the purpose, methodology, and potential significance of your study. Emphasize the importance of the research and its potential impact on the target population and related fields.

Example: “In conclusion, this proposed intervention research aims to design and evaluate a comprehensive school-based nutrition education program for elementary school students. The program will employ evidence-based strategies and interactive approaches to enhance students’ knowledge, attitudes, and behaviors related to healthy eating.

The study will utilize a quasi-experimental design, with data collected through various quantitative and qualitative methods, including surveys, dietary assessments, focus group discussions, and observational measures. Rigorous data analysis techniques will be employed to evaluate the effectiveness of the intervention and explore factors influencing its success.

The findings of this research have the potential to make significant contributions to the fields of nutrition education, childhood obesity prevention, and public health. By identifying effective strategies for promoting healthy eating habits among children, the study can inform the development and implementation of similar programs in schools and communities, ultimately contributing to the overall well-being of children and addressing a pressing public health concern.

It is hoped that this proposed intervention research will not only advance scientific knowledge but also have a positive impact on the target population and pave the way for future research and practice in this important area.”
