Quantitative Research Designs
In order to find the best information on a topic, not only should you develop a question and search for resources, but you should also know how to analyze the value of the resources that you identify. There are different ways to evaluate resources, such as using the hierarchy of evidence, which you explored in Week 4 of this course. Another way to evaluate resources is to consider the appropriateness of the research design. Understanding how research designs contribute to the quality of a study is essential for being able to analyze resources when conducting a literature review or locating evidence for practice.
In this Discussion, you consider the different research designs and evaluate how these designs have been used to research a specific topic. You also consider strategies for selecting an appropriate research design.
To prepare:
• Review the information in the course texton quantitative research designs. Focus on the information in Box 9.1, “Guidelines for Critiquing Research Designs in Quantitative Studies” located on page 230 of the course text.
• Select a topic from the list below and search the Walden Library to find two different quantitative research studies addressing that issue:
o Caregiver stress
o Anxiety in children
o Sleep apnea
o Depression in college freshmen
o Rural health care issues
o Post-traumatic stress syndrome
o Traumatic brain injury in veterans
o Health effects of environmental contaminants
o Bipolar disorder
o End-of-life ethical issues
o Alternative medicine
• For each of the sources that you select, identify the type of quantitative research design used, and evaluate whether it is the most appropriate approach to the research.
• Consider the ramifications of choosing an inappropriate design for a research study.
Post on or before Day 3 the topic you selected, references for the two sources you identified, and the quantitative research design used in each. Critique the appropriateness of the design used and justify your comments with information from the Learning Resources. Discuss the ramifications of choosing an inappropriate design for a research study.
NURS 6052: Essentials of Evidence-Based Practice “Quantitative Research for Evidence-Based Practice” Program Transcript
NARRATOR: Quantitative research includes any study or project that involves the use of numerical data or information that can be described using numbers. But having an effective research design is critical for the validity and success of all quantitative research ventures. In this video, Doctor Kristen Mauk speaks about the design of her DNP project, which explored the effect of education on new nurses in a rehabilitation unit.
Doctor Mauk's project can be considered a quantitative study, because it involved comparing the numerical results from tests that nurses completed before and after receiving educational materials, and then performing statistical tests to check for significance in the findings.
KRISTEN MAUK, PHD: I found a unit that was nearby, and they had opened a brand new rehab unit. And I collaborated with the nurse manager to see what would be the best methods for them to learn. And she said that her rehab staff didn't really have a lot of training specifically in rehab. They were experienced, wonderful nurses, but they were opening a new unit.
Well, my background was rehab, and I decided, ooh, well here was a good problem. Would education make a difference in their knowledge about rehabilitation? So that was my question. I designed, in collaboration with the nurse manager and the administration and using all those techniques about being a change agent, and communication, and people skills, we designed a project that fit that unit.
So first I went to the literature and found that, yes, knowledge makes a difference. If you're educating nurses, yes, they will-- if you give them education, that will result in better knowledge. So I designed a pre- and post-test using a tool that was already in existence to measure rehab knowledge. And I took 15 basic competencies of rehabilitation as set forth by the Association of Rehabilitation Nurses.

So you have to do your homework, and get your background, and kind of set up your methods, how you're going to work this. So I looked at what had other people done to measure knowledge outcomes, and a pre- and post-test design just was very logical. It measured their knowledge that they had coming in about these competencies, and then give them some education on it, and measure their knowledge going out.
They didn't have enough staff to perhaps cover shifts for each other. And in working with the organization, it shouldn't have had to cost them a lot of money. So in order to do those things, we had to modify our methods to make sure that it was something that was assessable, that wouldn't take a lot of time, that nurses could do in their down time that was available.
They could take their pre- and post-test at home if they wanted to, because it was online. And yet, when you mention technology, the nursing staff was mainly an older age group, so they didn't want the educational modules to be on the computer. They wanted them in paper and pencil form.
So for me, as the person implementing the project, that was a little bit challenging, because I was kind of used to the online form and had the PowerPoints. Now I had to translate those into what would I do if I was standing up teaching this as a course, and write all my notes at the bottom, and figure out how to put that in a paper and pencil module that was interesting, and not boring, and informative, and had the main points for people to learn.
Well, when you do your analysis, which would be quantitative, when I looked at the numbers of their pre- and post-test scores, then I could plug them in into the SPSS 14 statistical package, and it told me that I had a significant difference. It takes out all the variables as far as demographics, et cetera, so that I could attribute my intervention of the education to the difference in their scores, which were highly significant.
