Quantitative Research Designs

When exploring Evidence-Based Practice Nursing Essays and Research Papers, it’s essential to seek out the best information on a topic. This involves not only formulating questions and finding resources but also evaluating their quality. One way to do this is by considering the research design used in each study. Understanding how different research designs impact the quality of a study is crucial for analyzing resources effectively during literature reviews or evidence gathering.

This discussion focuses on examining various research designs and their suitability for investigating specific topics within Evidence-Based Practice Nursing Essays and Research Papers. Additionally, it discusses strategies for selecting the most appropriate research design.

To prepare:

  • Review the section on quantitative research designs in the course text, paying close attention to the guidelines for critiquing research designs in quantitative studies.
  • Choose a topic from the provided list and search the Walden Library for two different quantitative research studies addressing that topic.
  • For each selected study, identify the type of quantitative research design used and evaluate its appropriateness for the research.
  • Consider the potential consequences of selecting an inappropriate research design for a study.

Choose a topic from the list provided below and conduct a search in the Walden Library to locate two distinct quantitative research studies addressing that particular issue:

  • Caregiver stress
  • Anxiety in children
  • Sleep apnea
  • Depression in college freshmen
  • Rural health care issues
  • Post-traumatic stress syndrome
  • Traumatic brain injury in veterans
  • Health effects of environmental contaminants
  • Bipolar disorder

In this video, Dr. Kristen Mauk delves into specific quantitative research designs, methods, and considerations pertinent to her Doctorate of Nursing Practice (DNP) project. She elucidates how she formulated her research design and applied sound quantitative research methods throughout her project.

Validity in Quantitative Research Designs

Validity in research pertains to the confidence researchers can have in identifying causal relationships in their studies. Low validity indicates flawed research design, rendering the results largely inconsequential. Four facets of validity—statistical conclusion validity, internal validity, construct validity, and external validity—merit consideration when assessing the validity of quantitative research.

To prepare:

  • Review Chapter 10 of the course text focusing on rigor and validity in Evidence-Based Practice Nursing Essays and Research Papers.
  • Examine the method section of one of the quasi-experimental studies listed below and Evidence-Based Practice Nursing Essays and Research Papers. Identify at least one potential concern regarding the study’s internal validity.

  • Explore strategies to bolster the study’s internal validity and contemplate how this would affect the other three types of validity.
  • Reflect on the repercussions of an advanced practice nurse neglecting to scrutinize the validity of a research study when assessing its potential use in developing evidence-based practice.

Qualitative Research Designs

Over the past two weeks, our focus has been on delving into the intricacies of quantitative research designs. However, it’s important to note that quantitative approaches may not suit all research inquiries. For instance, you might be interested in understanding how patients respond to negative test results or investigating the evolution of perspectives on a particular health issue over time. In such cases, the emphasis lies more on grasping the thoughts and experiences of individuals or groups rather than relying solely on numerical data. For these types of inquiries, a qualitative or mixed methods research design proves most suitable.

In this Discussion, we delve into the various types of qualitative research designs, their applications, and their significance.

To prepare for Evidence-Based Practice Nursing Essays and Research Papers:

  • Reflect on the insights shared by Dr. Mauk in this week’s media presentation regarding the significance of qualitative research in nursing.
  • Access the journal Qualitative Health Research in the Sage Premier database available in the Walden Library.
  • Choose an article from this journal that piques your interest and was published within the last three years.
  • Familiarize yourself with the different qualitative research designs outlined in Chapter 21 of your course text.
  • Identify the qualitative research design employed in your chosen article and evaluate its suitability.
  • Consider any ethical considerations inherent in the study and how the researchers addressed them.
  • Ponder on how adopting a quantitative design would have impacted the nature of the data collected.

Planning for Data Collection

Data collection is a pivotal aspect of both quantitative and qualitative research methodologies. Regardless of the chosen approach, researchers must meticulously plan how data will be obtained, recorded, and stored while ensuring the reliability and validity of their methods. As nurses navigate through research to inform evidence-based practices, understanding sound data collection practices becomes imperative for assessing the credibility of presented data.

Consider the following scenario:

Healthcare professionals, including nurses, often seek to gauge patient satisfaction with healthcare services. Imagine yourself as a nurse working in a suburban primary care facility catering to approximately 10,000 patients annually. Your institution is keen on comprehending patients’ perspectives to pinpoint areas for improvement in care delivery. With this objective in mind, contemplate the development of a survey to evaluate patient satisfaction with the services rendered by your organization. Variables to consider may include ease of access to care, waiting times, staff friendliness, or the likelihood of patients recommending your institution to others.

For this Discussion, craft questions and devise an overarching plan for data collection that aligns with the aforementioned scenario.

To prepare:

  • Refer to the guidelines for generating questions outlined in this week’s Learning Resources.
  • Reflect on the scenario and formulate a minimum of five questions suitable for evaluating patient satisfaction.
  • Review the different data collection methods or instruments delineated in Chapters 13 and 23 of the course text.
  • Determine which methods or instruments would be most appropriate for the scenario. Additionally, establish an adequate sample size for the envisioned survey.

Weighing the Evidence for Evidence Based Practice Nursing Essays and Research Papers

When conducting original research, researchers must engage in the final step of weighing the evidence and interpreting the meanings inherent in their data, statistics, and analyses. This pivotal stage marks the culmination of the research process, where various research methods and designs converge to form a cohesive and meaningful conclusion. During this phase, researchers are tasked with formulating explanations based on their data, assessing whether the data effectively addresses their initial research questions, identifying areas of uncertainty, and contemplating avenues for further exploration.

In the context of Evidence-Based Practice Nursing Essays and Research Papers, individuals delve into a selected research article identified during Part 2 of the Course Project (Literature Review). Their objective is to dissect the process by which researchers derive conclusions from their data, explore alternative interpretations, and propose ideas for subsequent research endeavors.

To prepare:

  • Review this week’s Learning Resources, with a focus on how researchers derive meaning from their data and develop robust conclusions. Pay close attention to Table 2 in the article, “Study Design in Medical Research.”
  • Revisit the five articles identified in Part 2 of the Course Project and select one for closer examination in this Discussion.
  • Thoroughly examine sections of the chosen article where data is presented, analyzed, and interpreted for meaning. Evaluate the reasoning process employed by the researchers to formulate their conclusions and the explanations provided to support them. Identify any weaknesses in their analysis or conclusions.
  • Consider potential alternate conclusions that the researchers could have drawn based on their data.
  • Scrutinize the article’s findings and assess how effectively they address the researcher’s initial question(s). Propose additional research avenues that could augment these findings and provide a more comprehensive understanding of the underlying question.
