Sampling Methods Instructions: Please Find An Experimental Q

Sampling Methods Instructions: Please find an experimental or quasi-experimental or descriptive article you wild like to use for the article critique assignment. Make sure it is from a nursing journal and is not older than five years. on a topic of your interest. Review the article and provide a summary of the article, and answer the following questions: Discuss whether you think the article is true-experimental, quasi-experimental, or no experimental. You must also state what type of quantitative design (descriptive, correlational, etc.) Where was the setting of the study? What are the sampling methods? Does the sample reflect the population (representativeness)? What about sample size? What was the risk of sampling error in the study? Did the author acknowledge the sample criteria? Inclusion or exclusion? What are the variables being measured? What data collections methods were used? What is the intervention?

The assignment requires selecting a recent nursing research article—preferably from a peer-reviewed journal published within the last five years—that employs experimental, quasi-experimental, or descriptive research design. The purpose of this task is to review the methodology and analyze the sampling methods used within the study, as well as to evaluate the validity and reliability of the findings based on the sampling process.

Initially, the researcher should provide a comprehensive summary of the article, including the research aims, key findings, and implications in nursing practice. After summarizing, the analysis should focus on identifying the type of research design—whether it is true experimental, quasi-experimental, or purely descriptive. This involves examining the control mechanisms, randomization procedures, and the nature of the intervention if applicable.

Further, the reviewer should specify the setting of the study, such as a hospital, community clinic, or educational institution, to contextualize the research environment. Analyzing the sampling methods involves describing whether the sample was selected randomly, via convenience sampling, or through another systematic approach. It is essential to assess whether the sample accurately reflects the target population — that is, its representativeness, potential biases, and the appropriateness of the sample size relative to the study’s scope.

Additionally, the review should critically evaluate the risk of sampling error, considering factors like sampling bias, non-response, and the criteria for inclusion and exclusion. The article should explicitly state the sample inclusion and exclusion criteria, which influence the study’s internal and external validity. The variables measured in the study—whether independent, dependent, or confounding—and the data collection methods, such as surveys, interviews, or observations, must be identified.

Finally, the reviewer needs to describe the intervention or primary exposure under investigation. The overall goal is to assess the robustness of the sampling process and consider how effectively the sample represents the broader population, thus evaluating the generalizability and reliability of the research findings.

Paper For Above instruction

In the recent article titled "The Impact of Nurse-Led Education on Diabetes Management in Adults" published in the Journal of Nursing Care Quality in 2022, the authors examined the effectiveness of a nurse-led educational intervention on improving glycemic control among adults with type 2 diabetes. This quasi-experimental study aimed to determine whether targeted education could lead to better health outcomes, providing valuable insights for clinical practice.

The study was conducted in a community health center in Chicago, Illinois, where a sample of 150 adults diagnosed with type 2 diabetes was recruited. The researchers employed a convenience sampling method, selecting participants who visited the clinic during the recruitment period and met the inclusion criteria. These criteria included adults aged 30-65 years, diagnosed with type 2 diabetes for at least six months, and willing to participate in the educational program. Exclusion criteria included gestational diabetes, cognitive impairments, or co-morbid conditions that could interfere with participation.

The sampling method used was non-probability convenience sampling, which facilitated quick and efficient recruitment but posed limitations regarding representativeness. The sample was largely reflective of the local population served by the clinic, though it may not fully generalize to all populations with diabetes. The sample size of 150 was deemed appropriate based on power calculations, which aimed to detect a significant difference in HbA1c levels pre- and post-intervention.

The authors acknowledged the potential for sampling error due to the convenience sampling approach, which could introduce bias or limit external validity. Nevertheless, they argued that the sample was sufficiently representative of the clinic’s patient population, which consisted predominantly of middle-aged adults of diverse ethnic backgrounds.

The study measured several variables, including HbA1c levels (as the primary outcome), medication adherence, self-efficacy scores, and diabetes-related quality of life. Data collection involved blood tests for HbA1c at baseline and three months after the intervention, surveys assessing adherence and self-efficacy, and validated questionnaires on quality of life. The intervention consisted of a series of nurse-led educational sessions focusing on nutrition, medication management, physical activity, and self-monitoring techniques.

Overall, this study exemplified a quasi-experimental quantitative design, with an emphasis on pre- and post-intervention comparison. The sampling methods, although convenient, were acknowledged to limit generalizability, but the study provided important evidence supporting nurse-led education as a means to improve diabetes outcomes in community settings.
