Discussion: Observational Study Designs (NURS 6700 Week 3 / Module 2, Walden University)
The Week 3 discussion in NURS 6700 focuses on observational study designs in epidemiology (typically ecological, cross-sectional, case-control, and cohort studies). Students analyze provided or selected articles that use these designs, identify the specific design employed, discuss its strengths and limitations in the context of the study, and relate it to broader epidemiologic principles.
From student-submitted documents for this exact course:

The discussion requires reviewing one or more assigned articles on observational designs.
A commonly referenced article is: “Risk factors for stillbirth and early neonatal death: a case-control study in tertiary hospitals in Addis Ababa, Ethiopia” (a case-control study).
Students typically post an introduction explaining observational studies (how they evaluate associations between risk factors/exposures and outcomes through patterns in populations, without intervention), then analyze the article(s) by identifying the design, strengths/limitations, and relevance.

Standard Walden Discussion Format (applies here, based on similar NURS 6700 and NURS 8310 posts):

By Day 3: Post your initial response (main post) addressing the prompt on observational study designs, including analysis of the article/design.
By Day 6: Respond to at least two colleagues’ posts, engaging with their analyses (e.g., agreeing/disagreeing on design suitability, adding insights on bias, confounding, etc.).

Typical elements in student main posts for this week include:

Defining observational studies and contrasting them with experimental designs.
Describing the four main observational designs (ecological, cross-sectional, case-control, cohort) with brief strengths/limitations.
Summarizing the assigned article, identifying its design (e.g., case-control), explaining why it fits, and discussing methodologic aspects like selection of cases/controls, temporality, potential biases, or generalizability.
Linking back to population health implications or evidence-based practice.

Note: Exact wording of the prompt (including any specific required readings, articles, or questions like “Identify the study design used and evaluate its appropriateness”) is provided in your course’s Blackboard/Canvas learning management system under Week 3 > Discussion. Student documents confirm the focus is on applying concepts from the module’s readings (likely Friis & Sellers or similar epidemiology text) to real articles.
Walden discussions are graded on:

Timeliness and completeness of initial post.
Quality of analysis and use of evidence/references (APA).
Engagement in responses (thoughtful, substantive replies).
Adherence to the rubric (usually available via “Week 3 Discussion Rubric”).
