Reviewed by Emmett Rockwell, MBA Arizona State University Updated October 2026

This HCD 400 Module 3 sample answers the rigor essay set in the third module of Evidence Odyssey, ASU's senior research course for the Health Care Administration and Policy degree. For 50 points, ASU HCD 400 wants students to evaluate a peer-reviewed article's methodological rigor by examining its authenticity, reliability and credibility through four lenses: authorship, research methodology, sources and publication context. The composite student appraises the community health worker trial she found in Module 2. She looks at who wrote it and where, how it was published, how patients were recruited, randomized and followed, how outcomes were measured and analyzed and how its references and venue support the claims.

Can This Trial Be Trusted? Weighing the Authorship, Methods, Sources and Publication Context of a Community Health Worker Study

Introduction

In Module 2, I found a randomized trial testing whether community health workers improved outcomes for low-income patients with several chronic conditions (Kangovi et al., 2018). Before relying on it, I need to judge whether it is authentic, reliable and credible. This essay examines the article through four lenses: authorship, methodology, sources and publication context.

Authorship

The authors are physicians, statisticians and program staff affiliated with a large academic medical school and a center devoted to community health workers. That expertise is a strength, because the team understands both the clinical setting and the statistics. It also raises a question of independence: several authors helped design the program they are testing. The article discloses funding and author roles, which lets readers weigh this, and the presence of a biostatistician among the authors supports the analysis.

Research Methodology

The study is a randomized clinical trial, the design best suited to showing that a program, rather than chance or patient differences, produced a result. Eligible patients came from three primary care practices, lived in high-poverty ZIP codes, had public coverage or none and carried at least two chronic diagnoses; they were randomly assigned to the community health worker program or to goal setting alone. Outcomes were defined before the trial began, with self-rated physical health as the primary outcome, and analysis followed the intention-to-treat principle, so every patient was analyzed in the arm chosen by randomization, even those who disengaged from the program. These features protect against bias.

Some limits deserve attention. The trial was single-blind, but patients knew whether they were working with a community health worker, so self-reported outcomes may be influenced by expectations. The primary outcome did not differ between groups, while hospital use and care quality ratings did; a careful reader should give more weight to the primary result and treat secondary results as supportive rather than definitive.

What this page is doingDistinguishing the primary outcome from secondary ones is a mark of rigorous reading, and it keeps the essay from overstating what the trial showed.

Sources

The article's references include prior trials, systematic reviews and established measurement tools, cited where the authors make claims about earlier evidence. The authors also cite their own earlier work on the program, which is appropriate but means a reader should check whether independent studies agree. A systematic review of U.S. studies, which I found separately, reports mixed effects of community health workers on hospital use (Jack et al., 2017), suggesting the trial's results should be read in that broader context. A review of randomized trials of community-based health workers among vulnerable populations (Kim et al., 2016) shows that most such trials target prevention rather than hospital use, so this trial adds to a thinner part of the evidence.

Publication Context

The trial appeared in a peer-reviewed general medicine journal with editorial review, alongside an invited commentary, which signals that editors considered it important enough to discuss. Publication in a well-regarded journal does not guarantee correctness, but it means the methods passed external review.

Conclusion

The trial is authentic and credible: its authors are qualified and transparent, its design is strong and its venue is reputable. Its reliability is strongest for the outcomes it measured objectively, such as hospital days, and weaker for self-reported outcomes. I will use it as solid evidence that community health workers can reduce hospital use for some patients, while noting that its primary outcome was not improved.

What the HCD 400 Module 3 instructions ask for

The Module 3 Assignment, worth 50 points, asks for an essay that systematically evaluates the methodological rigor of peer-reviewed sources. The syllabus names the elements to examine: authenticity, reliability and credibility, through a comprehensive look at authorship, research methodology, sources and publication context. It builds directly on Module 2, so appraising a source you already found keeps your work connected. The five percent limit on quoted material still applies, and the course expects APA citations throughout. Open the complete article through the ASU Library instead of stopping at its abstract, because judgments about methods depend on details such as how participants were assigned and how outcomes were measured. Expect the Module 3 reading assessment on methods and statistics to help here, since terms such as randomization and intention-to-treat appear in both.

Inside the HCD 400 Module 3 example

Four sections follow the four lenses the syllabus names. The authorship section describes the team's expertise and affiliations and raises the question of independence that arises when developers test their own program. The methodology section explains the design, eligibility, randomization, prespecified outcomes and intention-to-treat analysis, then names the limits of unblinded self-reports and the null primary outcome. The sources section looks at how the article uses prior work and checks it against an independent review. The publication context section considers the journal and the accompanying commentary. The conclusion separates authenticity, credibility and reliability and states how the writer will use the study.

HCD 400 Module 3 rubric: what earns full marks

Fifty points are available under the Canvas rubric. Rigor essays are generally credited for addressing all four elements, explaining why each feature strengthens or weakens trust in the study, accurate description of the design and analysis, attention to conflicts of interest and limitations, use of an outside source to check the study's place in the literature and a clear overall judgment. Essays lose credit when they summarize the article's findings instead of evaluating its methods, when they treat publication in a journal as proof of quality and when they overstate results, for example by reporting secondary outcomes as the main finding.

HCD 400 Module 3 help with common mistakes

Many students summarize the study and add "it is credible" at the end. Instead, judge each feature: say what it is and whether it makes the findings more or less trustworthy. Read the methods section closely. Identify the primary outcome and report whether it was met. Look up the authors' affiliations and funding disclosures. Check the study against at least one independent source. Paraphrase rather than quote to stay under the five percent limit. The desk can help you plan the four sections if you share the article you chose. A useful habit is to write one sentence per lens before drafting: who wrote it, how it was built, what it rests on and where it appeared. Those four sentences become the spine of the essay.

What does the HCD 400 Module 3 assignment ask?

To evaluate a peer-reviewed article's methodological rigor by examining authenticity, reliability and credibility through authorship, methodology, sources and publication context.

What is the primary outcome of a study?

The outcome the investigators named in advance as the main test of the intervention; secondary outcomes support it but carry less weight.

Why does randomization matter?

Because chance alone decides who receives the program, the two arms start out alike in measured and unmeasured ways, so later gaps can more confidently be credited to the program.

It is worth 50 points.
