The selection of a population sample is a crucial element in any research study. It is essential to ensure that the sample represents the target population, to obtain reliable and valid results. In this article, we will analyze a research study and evaluate the effectiveness of the sampling strategy used.
The research article selected for analysis is “The Impact of Nurse-Led Education on Self-Care Behaviors and Glycemic Control among Patients with Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis.” The article’s link is
Overview of the study:
The study aimed to evaluate the effectiveness of nurse-led education in improving self-care behaviors and glycemic control among patients with type 2 diabetes. The researchers conducted a meta-analysis and systematic review of randomized controlled trials (RCTs) published between 2010 and 2020. The study included a total of 16 RCTs, with a combined population of 1684 diabetic patients.
The sampling strategy used in this study was purposive sampling. The researchers selected the studies based on specific inclusion and exclusion criteria. They included RCTs that evaluated the impact of nurse-led education on self-care behaviors and glycemic control among patients with type 2 diabetes. The studies had to include adult patients diagnosed with type 2 diabetes, provide nurse-led education, and report pre- and post-intervention glycemic control measures.
Evaluation of sampling method:
Purposive sampling is an effective method for selecting a sample from a population when a specific criterion or characteristic is required. In this study, the researchers used purposive sampling to include RCTs that met the inclusion and exclusion criteria. However, one limitation of purposive sampling is the potential for selection bias. The researchers may have excluded studies that did not fit the criteria, leading to a non-representative sample.
The study’s sample selection strategy was purposive sampling, which was effective in selecting RCTs that met specific inclusion and exclusion criteria. However, the potential for selection bias is a limitation of purposive sampling. Overall, the study’s findings suggest that nurse-led education is effective in improving self-care behaviors and glycemic control among patients with type 2 diabetes.
