Discussions1.Quantitative Research DesignsIn 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 text on quantitative research designs. Focus on the information on, Guidelines for Critiquing Research Designs in Quantitative Studies.· Select a topic from the list below and search the Walden Library to find two different quantitative research studies addressing that issue:o Caregiver stresso Anxiety in childreno Sleep apneao Depression in college freshmeno Rural health care issueso Post-traumatic stress syndromeo Traumatic brain injury in veteranso Health effects of environmental contaminantso Bipolar disordero End-of-life ethical issueso 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.RESOURCESRequired ReadingsPolit, D.

It describes different research designs and their key features and discusses how to plan for data collection.Chapter 9, Quantitative Research DesignThis chapter explores quantitative research in greater depth including the importance of experimental design and the role of randomization in conducting research. The chapter also describes quasi-experimental design and observational research.MediaLaureate Education (Producer). (2012m). Quantitative research for evidence-based practice. Baltimore, MD: Author.In this video, Dr. Kristen Mauk explains specific quantitative research designs, methods, and considerations related to her Doctorate of Nursing Practice (DNP) project. She discusses how she developed her research design and how she used sound quantitative research methods throughout her project.2.Validity in Quantitative Research DesignsValidity in research refers to the extent researchers can be confident that the cause and effect they identify in their research are in fact causal relationships. If there is low validity in a study, it usually means that the research design is flawed and the results will be of little or no value. Four different aspects of validity should be considered when reviewing a research design: statistical conclusion validity, internal validity, construct validity, and external validity. In this Discussion, you consider the importance of each of these aspects in judging the validity of quantitative research.To prepare:· Review the information in Chapter 10 of the course text on rigor and validity.· Read the method section of one of the following quasi-experimental studies. Identify at least one potential concern that could be raised about the studys internal validity.o Metheny, N. A., Davis-Jackson, J., & Stewart, B. J. (2010).

However, quantitative designs are not appropriate for all research questions. Perhaps you are concerned with how patients react when confronted with negative test results, or you wish to study how views on a certain health topic change over time. In each of these cases, the emphasis is more on understanding the thinking and experiences of an individual or group than on numerical measurements. For these types of questions, a qualitative or mixed methods research design is the most appropriate.For this Discussion, you focus on the different types of qualitative research designs, when they are used, and why they are important.To prepare:· Reflect on the comments made by Dr. Mauk in this weeks media presentation on the value of qualitative research in nursing.· Locate the journal Qualitative Health Research in the Sage Premier database in the Walden Library.· From this journal, select an article of interest to you that was published within the last 3 years.· Review the information on different qualitative research designs in Chapter 21 of your course text.· Determine what qualitative research design was used in your selected article and evaluate whether it was the best choice.· Consider ethical issues involved in the study and how the researchers addressed them.· Think about how using a quantitative design would have affected the type of data gathered.RESOURCESRequired ReadingsPolit, D.

Dr. Mauk explains the advantages of qualitative research as well as strategies for increasing credibility when conducting qualitative or mixed methods research.4.Planning for Data CollectionData collection is an important part of both quantitative and qualitative research. Although the actual approach to gathering information may vary, for either research design, researchers need to plan in advance how the data will be gathered, reported, and stored, and they need to ensure that their methods are both reliable and valid. As nurses review research when considering a new evidence-based practice, it is important to be familiar with sound collection practices in order to ascertain the credibility of the data presented.Consider the following scenario:Nurses and other health care professionals are often interested in assessing patient satisfaction with health care services. Imagine that you are a nurse working in a suburban primary care setting that serves 10,000 patients annually. Your organization is very interested in understanding the patients point of view to help determine areas of care that can be improved. With this focus in mind, consider how you would create a survey to assess patient satisfaction with the services your organization provides. You may wish to consider variables such as the ease of accessing care, patient wait time, friendliness of the staff, or the likelihood that a patient would recommend your organization to others.For this Discussion, you generate questions and an overall plan for data collection that would be appropriate for a patient satisfaction survey in relation to the above scenario.To prepare:· Consider the guidelines for generating questions presented in this weeks Learning Resources.· Review the scenario and formulate at least five questions that you could use to evaluate patient satisfaction.· Reflect on the different methods or instruments that can be used for gathering data described in Chapter 13 and Chapter 23 of the course text.· Which methods or instruments would work well for the scenario? Determine an appropriate sample size for the scenario.RESOURCESRequired ReadingsPolit, D. F., & Beck, C. T. (2017).

David Company.Chapter 9, Evaluation of Research Instruments and Experimental Conditions5.Weighing the EvidenceWhen conducting original research, the final step researchers must complete is weighing the evidence and interpreting the meanings of their data, statistics, and analyses. This is the culmination of the research process in which all of the research methods and designs can be synthesized into a meaningful conclusion. In this stage, researchers should formulate explanations for what their data indicates, determine whether the data answers their initial research question, identify areas of uncertainty, and consider directions for further research.In this Discussion, you focus on one of the research articles that you identified for Part 2 of the Course Project (Literature Review). You then explore the process of how the researchers generated conclusions based on their data, consider other possible interpretations of their data, and formulate ideas for further research.To prepare:· Review this weeks Learning Resources, focusing on how researchers find meaning in their data and generate sound conclusions. Pay particular attention to Table 2 in the article, Study Design in Medical Research.· Revisit the 5 articles that you identified in Part 2 of the Course Project. Select one to consider for the purpose of this Discussion.· Read sections of the chosen article where the data is presented, analyzed, and interpreted for meaning. What reasoning process did the researchers use to formulate their conclusions? What explanation did they give to support their conclusions? Were there any weaknesses in their analysis or conclusions?· Consider possible alternate conclusions that the researchers could have drawn based on their data.· Examine the findings that the article presents and consider how well they addressed the researchers initial question(s). What additional research could be done to build on these findings and gain a fuller understanding of the question?RESOURCESRequired ReadingsPolit, D. F., & Beck, C. T. (2017).
