DNP 955 Topic 5: Chapter 3 methodology
This chapter expands the strategic points, which means every claim in it is checkable against Appendix A. The commonest failure is a methodology that has quietly moved on from the points that were approved.

Chapter three expands Appendix A — it cannot contradict it
The dependency stated in the brief is the constraint that governs this chapter. Chapter three expands the strategic points you finalised in Topic 2, so a reviewer will read the two against each other. If your thinking has developed — and over several topics it usually has — the honest move is to go back and amend the strategic points with your committee rather than to let chapter three quietly diverge. A methodology chapter contradicting its own appendix is a governance problem as much as a writing one, because the committee approved the appendix. Resolve the divergence before you submit rather than defending it afterwards. Note also what this chapter is not. It is not the place to re-argue that the problem matters — chapters one and two did that — and a methodology chapter that opens with three paragraphs of significance has spent space it will need later. Every paragraph should answer how, and a reviewer notices when one answers why.
Within the chapter, write for reproducibility. The test is whether someone else could run your project from this text alone, and it is a demanding standard that exposes most vague writing. Sample means the inclusion and exclusion criteria, the recruitment route, the size and how you arrived at it. Instrumentation means the named tool with its psychometrics, its licence status, and who administers it. Data collection means the sequence, the timing relative to the intervention, and who holds the data. Analysis means the named test with the assumptions you will check, decided before any data exists — because choosing an analysis after seeing results is the thing pre-specification prevents. Include the ethical considerations and the limitations honestly; a chapter that claims no limitations reads as one that has not looked. Where a decision was forced by practicality rather than ideal design, say so and say what it costs, since a reviewer will find it anyway.
