HS860: Doctoral Project I: Project Proposal

Unit 4 Purpose and Question Alignment

[Instructor Name]

[Date]

The project is composite and no data have been collected; the design source cited is real.

What this part is doingNaming the verbs that were cut tells the committee the revision is about scope, the most common reason doctoral purposes fail.

The First Draft and Its Problem

The first draft read: "The purpose of this project is to examine lymphedema surveillance at the center, understand barriers to participation and improve early detection of lymphedema." Each verb promises something different. Examine is vague; it could mean anything from counting visits to auditing clinical decisions. Understand barriers implies an explanation of causes, which needs a design able to support causal claims. Improve early detection promises an outcome, which would require an intervention, a comparison and a follow-up period longer than the program allows. Read against the problem statement, which describes a gap in knowledge about where and why women leave the pathway, only part of the first verb and part of the second belong.

The Revised Purpose

This project, using an explanatory sequential mixed methods design, aims to describe where, among women who had axillary lymph node dissection at a community cancer center over a two-year period, women leave the lymphedema surveillance pathway, and to explore how women and staff explain those departures.

The pathway in question is the center's version of the published surveillance model, which pairs a measurement before treatment with measurements at set intervals afterward (Stout et al., 2012). Describe is the governing verb. Explore is a qualitative verb that promises accounts, not causes. Improve is gone, and the project's conclusions will be limited to what the data can show.

The revised purpose promises less than the first draft, and that is its strength: everything it promises, the design can deliver.

What this part is doingDefending the smaller purpose explicitly anticipates the committee's most likely question, whether the project has become too modest.

The Research Questions

Research question one, quantitative: Among women who had axillary lymph node dissection at the center during the study period, what proportion completed each step of the surveillance pathway, a preoperative baseline measurement, a surveillance referral at discharge and a first surveillance visit within four months, and at which step did the largest share leave?

Research question two, qualitative: How do women who left the pathway, and the staff responsible for each step, explain why those steps were or were not completed?

The questions are sequential. The first locates the failure; the second explains it, and its interview sample will be drawn according to where the first question finds the largest losses (Ivankova et al., 2006).

The Alignment, Element by Element

Problem: community cancer centers do not know where or why high-risk women leave surveillance pathways.

Purpose: describe where women leave and explore how women and staff explain it.

Question one: proportions completing each step and the step with the largest loss.

Data for question one: structured fields in the electronic health record, namely the preoperative measurement flowsheet, the referral order and the scheduling record for the lymphedema clinic, for all eligible women over two years.

Analysis for question one: descriptive statistics, a step-by-step attrition count and proportions with confidence intervals, with comparisons by age group, surgery type and insurance where numbers allow.

Question two: explanations from women and staff.

Data for question two: semi-structured interviews with about [12] to [15] women who left at the step with the largest loss and [6] to [8] staff from the relevant services.

Analysis for question two: thematic analysis, with themes compared against the step-by-step results.

Integration: a joint display placing each step's completion proportion beside the explanations offered for losses at that step, the standard way of bringing the two strands together in this design (Creswell & Plano Clark, 2018).

Checks Applied

Each element was checked against the next. Does the purpose follow from the problem? Yes; the problem is a gap in knowledge about where and why, and the purpose is to describe where and explore why. Does each question serve the purpose? Yes; one each. Does each question need its own data? Yes; question one needs records and question two needs interviews. Can the analysis answer each question? Yes, and neither analysis claims more than description and explanation. Would any question be answered by the same table as another? No.

What the Alignment Removes

Two things were removed because they failed the checks. A third question, on whether women who completed surveillance had less severe lymphedema at diagnosis, would require following women for two years after surgery and comparing groups that differ in many ways, which the design cannot support. A question about the cost of late diagnosis was removed because cost data are not available at the center. Both remain good questions for later work, and the final chapter of the eventual dissertation can name them as directions for future study rather than leaving them out entirely.

What this part is doingRecording what was cut, and why, shows the committee that the narrowing was deliberate rather than accidental.

Remaining Risk

The alignment assumes that the record captures each step in a structured field. If preoperative measurements are recorded in free-text notes, question one becomes far more labor-intensive. The feasibility appraisal in a later unit will test this assumption before the proposal is final.

Reading the HS 860 Unit 4 instructions

The fourth unit usually asks candidates to revise their purpose statement and research questions and show how they align with the problem, design, data and analysis. A table or element-by-element list is common, along with a few pages of explanation. Instructors look for a purpose with a single governing verb that matches the design, research questions that each need their own data and analysis, and nothing promised that the design cannot deliver. Descriptive and exploratory designs should not claim to establish causes or improvements. Many prompts ask candidates to explain what they removed and why. A note on the most important remaining risk, often whether the data will exist in usable form, helps connect this unit to later feasibility work.

How the HS 860 Unit 4 example is put together

The paper quotes the first-draft purpose and explains what each of its three verbs would require. The revised purpose follows, with describe and explore defined, and the highlighted sentence argues that promising less is a strength. Two research questions are stated, sequential in logic. An element-by-element alignment runs from problem through purpose, questions, data sources, analysis and integration in a joint display. A checks section answers five alignment questions in turn. A section explains why a question about lymphedema severity and another about cost were removed. The paper closes with the risk that preoperative measurements may sit in free text, to be tested in the feasibility appraisal.

Where the points sit in the HS860 Unit 4 rubric

Alignment assignments are commonly assessed on the precision of the purpose statement, the quality of the research questions, the consistency of the alignment, the justification of changes and writing. Precision and consistency usually carry the most weight, since misalignment is the most common reason doctoral proposals are returned. Research questions earn credit when each is answerable, distinct and matched to the design's capabilities. Justification points reward candidates who explain what was cut and why, rather than silently narrowing. Graders also check that analysis plans match the level of the data. A clear table or list, a single governing verb and correct APA citation complete the score. Purposes that promise outcomes beyond the design usually lose points.

HS860 Unit 4 help: mistakes that cost points

The most frequent error is a purpose statement with several verbs, each implying a different design. Another is research questions that would be answered by the same table, which suggests they are really one question. Some candidates ask why questions in a records-only design that cannot explain causes. Others drop a question without explaining the reason, leaving the committee to wonder. Alignment tables that list elements without showing how each follows from the last miss the point. If your project uses another design, perhaps a pre-post comparison or a qualitative descriptive study, send your problem statement and draft purpose, and an alignment can be prepared that keeps every element in step.

HS860 Unit 4 questions, answered

What does alignment mean in a doctoral proposal?

Consistency between the problem, purpose, research questions, design, data and analysis, so each element follows from the one before and promises no more than the next can deliver. A misaligned proposal might describe a problem about access, state a purpose about satisfaction and ask a question about cost. Committees check alignment early because every later chapter depends on it.

Can a descriptive project ask why?

It can ask how people explain their choices, which is a legitimate descriptive question, particularly in qualitative work. What it cannot do is claim to establish causes, which usually requires a comparison, an intervention or a design built to rule out alternatives. Wording the question accordingly, about described reasons rather than causes, keeps the promise honest.

How many research questions should a doctoral project have?

Often two or three, and sometimes one. Each question should require its own data or analysis; if two questions would be answered by the same table, they are probably one question. Adding questions to seem thorough usually creates alignment problems, since each new question makes a promise the design must keep.

Where can I find a free HS860 Unit 4 sample paper?

This page presents the complete Unit 4 purpose and question alignment, revising a three-verb purpose into one that a two-strand design can fully deliver.

Why was improve removed from the purpose?

Improvement requires an intervention, a comparison and enough follow-up to see change, none of which a descriptive project at one site can provide.
