Composite county written as a model document. The two US studies and the interview study are composites, shown with bracketed citations.
Appraisal Table
1. Notley et al. (2019), Cochrane review of incentives for smoking cessation. Tool: AMSTAR 2, suited to systematic reviews (Shea et al., 2017). Finding: in pregnancy, incentives conditioned on verified abstinence more than doubled quit rates at the longest follow-up (Notley et al., 2019). Rating: high confidence. Transferability: the trials were mostly outside rural America.
2. Tappin et al. (2015), randomized trial in Glasgow. Tool: EPHPP, which rates selection bias, design, confounders, blinding, data collection and withdrawals (Thomas et al., 2004). Finding: shopping vouchers tied to carbon monoxide-verified abstinence produced late-pregnancy quit rates of 22.5 percent against 8.6 percent (Tappin et al., 2015). Components: strong on design, data collection and withdrawals; weak on blinding. Global: moderate. Transferability: urban Scotland, with universal health care.
3. [Author, year], pre-post evaluation of a US voucher program. Tool: EPHPP. Weak on selection bias and confounders. Global: weak. Transferability: a US delivery setting close to Cordell's.
4. [Author, year], cohort of pregnant quitline callers. Tool: EPHPP. Weak on selection bias and confounders. Global: weak. Transferability: state quitline similar to Cordell's.
5. [Author, year], interviews with rural pregnant smokers. Tool: CASP qualitative checklist (CASP UK, 2018). Strong on data collection; recruitment through clinics may miss women outside care. Finding: distrust of programs that feel judgmental.
Why Blinding Is Weak but Not Fatal
No incentive trial can hide from a woman whether she is being paid, so blinding will always rate weak; biochemical verification of abstinence limits the harm, because a carbon monoxide reading cannot be talked up.
Synthesis
Strength and fit point in different directions. The strongest evidence, the Cochrane review and the Glasgow trial, comes from settings unlike Cordell. The closest settings, a US voucher program and a quitline cohort, come from the weakest designs. The qualitative study adds something neither can: rural women's reasons for distrusting quit programs, which bears directly on how an intervention should be delivered.
For Cordell, the conclusion is that verified incentives have the strongest evidence of effect, and that delivery must borrow from the US studies and the interviews: a trusted setting such as WIC, a nonjudgmental approach and attention to the barriers rural women describe. The weak US studies are kept rather than discarded, because they describe how an American program was actually delivered, which the Glasgow trial cannot.

How this NU465 Unit 3 example is structured
Order follows the evidence hierarchy downward, while the synthesis weighs by fit instead. The Cochrane review opens because it frames the question: across trials, incentives conditioned on verified abstinence more than doubled quitting in pregnancy. AMSTAR 2 is applied to it rather than EPHPP, and the paper explains that choice in one sentence, since a review and a trial fail in different ways. The Glasgow trial comes next with component ratings shown, including why blinding scores weak and why biochemical verification limits the harm. The two weak US studies follow, kept rather than discarded because they describe American delivery settings the trial could not. The qualitative study closes the table, rated on CASP, supplying rural women's reasons for distrusting quit programs. Synthesis then asks which evidence best fits Cordell, concluding that the strongest effect comes from abroad and the closest setting from the weakest designs.

Some sections name the appraisal tool; others leave it to the writer. If yours names one, whether Johns Hopkins, EPHPP or another, include that in the request with the Unit 3 prompt and rubric, plus any articles you have already chosen, and the model appraisal is written around them within 24-48h, free on a first order. The paper above is an original model document written by our desk, not a submitted student paper and not an official Purdue University Global document.
NU465 Unit 3 questions, answered
Can the Johns Hopkins evidence model be used instead of EPHPP?
Often, yes, if your section teaches it. The Johns Hopkins model grades evidence level and quality across designs and is common in nursing programs. EPHPP was built for public health intervention studies and asks more about selection bias and confounding in community settings. Whichever tool the prompt names should govern; where none is named, a sentence justifying the choice helps.
Why include studies rated weak?
Because rating a study weak is a finding, not a reason to hide it. In public health, the studies closest to a real delivery setting are often observational, and they carry information a trial abroad cannot. The appraisal keeps them visible, says exactly why they rate weak, and limits what they are allowed to support in the synthesis.
How many articles does a Unit 3 appraisal need?
That depends on the prompt, and sections vary widely. Quality of reasoning matters more than count; five papers appraised properly outscore ten summarized. If your instructions set a number or require a particular mix of designs, send them with the request, and the model will match that mix rather than the five used here.
