If your chair has approved the previous sections (title, supporting literature, problem), this week you will complete the Purpose section of the Prospectus Form. The Appendix located in the Prospectus Form describes how each element should be completed with examples.
Incorporating feedback from your chair, additional reading, and further thinking about your topic, revise all parts of your prospectus as needed to assure alignment. Particular attention should be directed toward the Problem, revising the research and social problems align them precisely with the Purpose.
How to Write the Purpose Section of a Dissertation Prospectus
Introduction
The purpose section of a dissertation prospectus serves as the bridge between the identified problem and the proposed research study. While the problem statement explains what issue exists and why it is significant, the purpose statement explains what the researcher intends to do to address or investigate that issue. A well-developed purpose statement demonstrates clear alignment with the research problem, social problem, theoretical foundation, and research questions. Alignment is critical because dissertation committees evaluate whether each section logically supports the others and contributes to a coherent research design (Creswell & Creswell, 2023).
As doctoral researchers continue refining their prospectus, it is common to revise earlier sections such as the title, supporting literature, and problem statement to ensure consistency with the developing purpose. The process of refinement helps strengthen the study’s focus and ensures that the proposed research can effectively contribute to existing knowledge while addressing a meaningful social issue. Therefore, careful attention must be given to ensuring that the purpose statement directly addresses the research problem and supports the overall goals of the study.
Section 1: Understanding the Purpose Statement
The purpose statement describes the overall intent of the study. It identifies the methodology, target population, central phenomenon or variables, and the specific objective of the research. Unlike the problem statement, which focuses on what is wrong or unknown, the purpose statement focuses on what the researcher will do to investigate or address the identified problem (Burkholder et al., 2020).
For example, if the problem statement identifies a lack of understanding regarding employee retention among remote workers, the purpose statement would explain that the study seeks to explore factors influencing employee retention among remote workers within a specific industry or population. The purpose statement should be concise yet comprehensive enough to communicate the study’s direction and scope.
An effective purpose statement typically answers several questions. It explains what will be studied, who will participate, where the study will occur if applicable, what methodology will be used, and how the study connects to the identified problem. By addressing these components, the purpose statement establishes a clear roadmap for the remainder of the dissertation.
Section 2: Ensuring Alignment Between the Problem and Purpose
One of the most important requirements of a prospectus is alignment between the problem statement and the purpose statement. Every aspect of the purpose should directly respond to the research problem identified earlier in the prospectus. If the problem statement identifies a gap in knowledge, the purpose statement should explain how the proposed study will investigate that gap. If the problem identifies a practical issue affecting a population, the purpose should explain how the study will contribute to understanding or addressing that issue (Ravitch & Carl, 2021).
The research problem and social problem must also remain aligned. The social problem explains why the issue matters in the real world, while the research problem identifies the specific gap in scholarly knowledge. The purpose statement should connect both elements by demonstrating how the proposed study contributes to knowledge while potentially informing solutions to the broader social issue.
Researchers should carefully review their prospectus to ensure consistency in terminology. Key concepts, variables, populations, and phenomena should remain consistent throughout the title, problem statement, purpose statement, and research questions. Misalignment often occurs when researchers introduce new concepts in the purpose statement that were not discussed in the problem statement or supporting literature.
Section 3: Components of a Strong Purpose Statement
A strong purpose statement includes several essential components. First, it identifies the research methodology. Qualitative studies often use language such as explore, understand, describe, or examine experiences. Quantitative studies typically use language such as examine relationships, determine effects, assess differences, or test hypotheses. Mixed-methods studies incorporate both qualitative and quantitative elements.
Second, the purpose statement identifies the target population. The population should be specific enough to clearly define who will participate in the study. Examples may include teachers, nurses, business leaders, social workers, students, or community members within a particular context.
Third, the purpose statement identifies the central phenomenon or variables being studied. In qualitative research, this may involve experiences, perceptions, or lived realities. In quantitative research, this may involve measurable variables and relationships between variables.
Finally, the purpose statement should indicate the intended contribution of the study. This contribution may involve filling a gap in the literature, informing policy, improving professional practice, or supporting social change. Including the study’s contribution helps demonstrate its significance and relevance.
Section 4: Sample Purpose Statement Framework
The following framework can be adapted to many doctoral studies:
For a Qualitative Study:
“The purpose of this qualitative [design] study is to explore the experiences of [population] regarding [phenomenon] in [setting]. The study seeks to address the gap in the literature concerning [research problem] and contribute to understanding factors that influence [topic].”
For a Quantitative Study:
“The purpose of this quantitative [design] study is to examine the relationship between [independent variable] and [dependent variable] among [population]. The study seeks to address the identified gap in the literature regarding [research problem] and provide evidence that may inform [practice, policy, or social change].”
For a Mixed-Methods Study:
“The purpose of this mixed-methods study is to examine [topic] among [population] by combining quantitative analysis of [variables] with qualitative exploration of [experiences or perceptions]. The study seeks to address the identified research problem and contribute to improved understanding of [topic].”
Section 5: Revising Previous Prospectus Sections
Once the purpose statement is drafted, researchers should revisit all previous sections to ensure alignment. The title should accurately reflect the purpose of the study and the target population. Supporting literature should provide evidence supporting both the research problem and the proposed purpose. The problem statement should clearly establish the need for the investigation described in the purpose statement.
Additionally, any conceptual framework, theoretical framework, or research questions should align directly with the purpose. Research questions should emerge naturally from the purpose statement and focus on addressing the identified problem. Consistency across sections strengthens the overall prospectus and demonstrates methodological rigor.
Researchers should also verify that terminology remains consistent throughout the document. Variations in wording may unintentionally suggest different research topics and create confusion for reviewers. Careful revision helps ensure that the prospectus presents a unified and logically connected research plan.
Conclusion
The purpose section is one of the most important components of a dissertation prospectus because it explains what the study intends to accomplish and how it will address the identified research problem. A strong purpose statement aligns directly with the problem statement, social problem, supporting literature, and research questions. It clearly identifies the methodology, population, phenomenon or variables, and anticipated contribution of the study. As researchers revise their prospectus, careful attention to alignment ensures that all sections work together to create a coherent and academically rigorous research proposal. Ultimately, a well-developed purpose statement provides a strong foundation for the successful completion of the dissertation process.
