Experimental Research: One example of experimental research in nursing is a study investigating the effectiveness of a new medication in reducing blood pressure among hypertensive patients (Zhou et al., 2021). In this study, researchers would randomly assign participants into two groups: one receiving the new medication (experimental group) and the other receiving a placebo (control group). They would then measure and compare the changes in blood pressure between the two groups, utilizing rigorous control over variables to establish causation. Experimental research involves manipulation of variables, random assignment, and control groups, allowing researchers to draw causal conclusions.
Quasi-Experimental Research: In a quasi-experimental study in nursing, researchers might examine the impact of a specific nursing intervention on patient outcomes. Unlike experimental research, quasi-experimental designs lack random assignment. For instance, comparing patient outcomes before and after the implementation of a new nursing protocol in a specific hospital unit (Middleton et al., 2023). While researchers can identify correlations and make inferences, they cannot establish causation definitively due to the absence of randomization. Quasi-experimental designs are practical when random assignment is not feasible or ethical.
Nonexperimental Research:Nonexperimental research in nursing often involves observational studies. An example is a study assessing the prevalence of nurse burnout in a hospital using surveys or interviews (Saravanan et al., 2022). Unlike experimental and quasi-experimental research, nonexperimental research does not involve manipulation of variables or control groups. It primarily focuses on observing and describing phenomena without attempting to establish cause-and-effect relationships. Researchers collect data through surveys, interviews, or observations and analyze the relationships among variables without intervening or manipulating them.
