Analyzing Research Designs: Experimental, Quasi, and Non-Experimental

This essay elucidates the distinctions between experimental, quasi-experimental, and non-experimental research designs within the context of healthcare. It presents three distinct research articles as examples: an experimental study employing a randomized clinical trial to assess the efficacy of different Lidocaine applications for intrauterine device insertion, a quasi-experimental study examining the impact of blanket temperatures on patient comfort, and a non-experimental study comparing pressure ulcer risk scales in a Korean hospital using a correlational design. The essay further discusses the purpose and effectiveness of each research design, highlighting that experimental designs evaluate treatments and interventions with random group selection, quasi-experimental designs determine causal relationships between treatment and comparison groups, and non-experimental designs explore relationships between variables through correlational studies. The essay concludes by referencing the research articles used as examples.

Experimental Article
Bayoumy et al. (2018) article is an example of an experimental research article because it
utilizes a randomized clinical trial method in the data collection process with two groups of
women participants randomly selected. The study looks at the efficacy of three types of
Lidocaine, topical spray, topical cream, and injection for intrauterine device insertion.
Quasi-Experimental Article
Sutton et al. (2012) article employed a quasi-experimental design since it uses two
different blanket temperatures for safety and comfort. The study randomized participants into
two groups that received blankets that received blankets at 155° and a control group that
received blankets at 110°. The study is a quasi-experimental since aims at determining a causal
relation between blanket temperature and patient comfort.
Non-experimental Article
A research study article by Eun-Kyung Kim et al. (2009) was not experimental. The
research article compared three pressure ulcer risk scales, Braden, Song and Choi, and Cubbin
and Jackson scale to evaluate the best predictor of pressure ulcer risk in a Korean hospital. The
research study employed a correlation design of the study.
Effectiveness of Research Designs
The purpose of the experimental study design is to evaluate experimental results such as
treatment and intervention process. In an experimental study, group selection is random, and one
of the two groups receives the experimental drug while the other group receives routine
treatment.

STATISTICS 3
Quasi-experimental research aims at determining a causal relationship between the
treatment and a comparison. Lastly, the non-experimental research study design looks at the
relationship between study variables thus as a correlation design.
