Week 10 Discussion: Peer Critique of Design and Claims
The Claim a Sound Design Cannot Carry: Peer Critiques Locating Exactly Where a Classmate's Completer-Only Evaluation and Another's County Before-and-After Comparison Overreach
Reply to Tomas
Tomas, your evaluation of the community health worker program that helps adults with diabetes manage their medications is carefully built. Your survey has good questions, and your interviews will capture rich experiences. My concern is with one claim in your draft: that the program "improves medication adherence." Your design surveys and interviews only people who completed the program.
The problem is not the survey or the interviews; it is who is missing. People who dropped out of the program, who may have had more trouble with their medications, will not appear in your data. Completers may also have been more motivated from the start. So even if completers report good adherence, the design cannot show the program caused it. Your design can support a different claim: "Completers report high adherence and describe what helped them." That is worth knowing. If you want to claim improvement, you need a comparison, perhaps adults referred to the program who did not enroll, measured at the same times, and you need to follow people who drop out. In mixed methods, it also helps to make clear how the interview strand will connect to the survey rather than running alongside it (Fetters et al., 2013).
Would you be able to add a short survey of people who left the program early?
Reply to Yasmin
Yasmin, your study tracking county uninsured rates before and after a health insurance navigator program is well documented, and your data sources are solid. The claim I'd question is that "the navigator program reduced the uninsured rate by four percentage points."
A before-and-after comparison in one county cannot separate the program from whatever else shifted during those years: state enrollment rules, a new employer in town, the local economy. If neighboring counties without navigators saw similar drops, the program's effect would be much smaller. Your design can support: "The county's uninsured rate fell by four points after the program began." To claim the program caused the drop, you would need comparison counties and, ideally, data on whether newly insured people actually used navigators. If you added interviews with newly insured residents about how they enrolled, a sequential design could help explain the county trend, as long as the claim stays matched to what each strand can show (Creswell & Plano Clark, 2018).
A Note on My Own Study
Writing these replies made me look at my study of hearing aid non-use. My survey includes only people fitted at clinics, so I cannot claim to describe all older adults with hearing loss. A review of non-use reasons drew on studies of people fitted with aids (McCormack & Fortnum, 2013), which is the same population as mine; my findings will speak to that group and should not be stretched further.

The Walden PUBH 8211 Week 10 instructions
Peer critique discussions late in a methods course ask students to evaluate whether classmates' designs support the conclusions they intend to draw. Prompts usually require identifying the claim, explaining why the design can or cannot support it, suggesting a claim the design can support and proposing changes that would allow the stronger claim. Instructors reward critiques that respect the classmate's design, locate the problem in a specific sentence, explain the threat precisely, such as survivorship or history, and offer feasible additions. Critiques that say only "this is not causal" without saying what would make it so earn little credit. Some sections assign each student two classmates' drafts to review.
Inside the PUBH 8211 Week 10 example
The first reply credits the classmate's design, names the overreaching claim and explains the problem of missing dropouts and self-selection. It offers a claim the design can support and suggests surveying people who left early, citing integration literature. The second reply follows the same pattern for a before-and-after comparison, naming confounding events and suggesting comparison counties and interviews. A closing note applies the test to the author's own study and limits its claims to people fitted with aids. Each reply ends with a practical question the classmate can answer. The author's own study is held to the same standard in a closing note.
Reading the PUBH 8211 Week 10 rubric
Graders evaluate precision, fairness and constructiveness. Credit is highest when the critique quotes the specific claim, names the threat accurately and proposes a claim the design can carry. Suggestions should be feasible for a doctoral student. Applying the test to one's own study shows reflection. Tone should be collegial. Accurate citations support the points. Critiques that dismiss a design rather than resizing its claims usually lose ground. Critiques that suggest an addition the classmate could realistically make, such as surveying early leavers, are more helpful than calls for a new design. Graders reward precise naming of threats like survivorship and history. Offering the claim a design can support, not only criticizing the one it cannot, demonstrates constructive scholarship. Replies that stay brief and focused are easier for classmates to act on.
PUBH 8211 Week 10 help: mistakes that cost marks
Students often critique designs instead of claims. Underline the claim the classmate makes, then list what evidence a design would have to produce before that claim could stand. Name the specific threat. Offer a smaller claim the design can carry. Suggest one addition that would allow the bigger claim. Test your own study the same way. Paste a classmate's design and claim to have a fair critique drafted. Quote the claim you are testing so the classmate knows exactly what you mean. Keep each reply to one main point. Thank the classmate for something specific. Offer the classmate a revised claim in one sentence.

Copy the classmates' conclusions and design descriptions you are critiquing, names removed, and add the Week 10 prompt and rubric. Critiques quoting each claim, explaining the mechanism that forbids it and offering a supportable replacement are back in 24-48h, and the first request is free. No real program, county or classmate stands behind them.

PUBH 8211 Week 10 questions, answered
Where can I find a free PUBH 8211 Week 10 sample paper?
Both Week 10 critiques are printed above, matching classmates' claims to what their designs can support.
Why can't a completer-only survey show a program works?
People who dropped out are missing, and completers may have been more motivated from the start.
What claim can a completer-only design support?
That completers report a given outcome and describe what helped them.
Why can't one county's before-and-after change show a program's effect?
Other events during the same period could explain the change without a comparison group.
What limit does the author place on her own study?
Findings describe adults fitted with hearing aids at the study clinics, not all older adults with hearing loss.
