Week 3 discussion

Theory, Research, and Evidence-Based Practice

As they explore the world around them, young children often want to know the “why” and “how” of the things they observe. This is similar to what researchers do when they approach a new problem. Researchers develop new theories or build on old ones to explain the “why” of the world around them. They use models and conceptual frameworks to help explain “how” the processes and events they observe occur. Together, theories and models provide an understanding of the world and allow researchers to explore it in meaningful ways.

Virtually all research questions can benefit from the use of an existing theory or model. Researchers should consider their research questions and select the most suitable theory or model, which then serves as a foundation for the research design. The selection of a theory or model is an important part of the research process.

In this Discussion, you focus on the role of theory and models in research and evidence-based practice.

To prepare:

Review the information in Chapter 6 of the course text. Focus on the various conceptual theories and models that are currently used in nursing research.

Select one of the theories or models described that is of interest to you.

Using the Walden Library, search for and identify a research article that uses the theory or model you selected.

Reflect on how the theory or model provides structure to the research study described in the article.

Now, think about an issue in your practice area that you would be interested in exploring through research.

Review this week’s media presentation and consider strategies for locating and identifying a relevant theory or model for a research study.

By Day 3

Post a summary of the article that you located and explain how the theory or model that you selected was used in the research study. Assess the value of basing research on an established theory or model.

Read a selection of your colleagues’ responses.

By Day 6

Respond to at least two of your colleagues on two different days using one or more of the following approaches:

Ask a probing question, substantiated with additional background information, and evidence.

Share an insight from having read your colleagues’ postings, synthesizing the information to provide new perspectives.

Offer and support an alternative perspective using readings from the classroom or from your own review of the literature in the Walden Library.

Week 4 discussion

Ethical Dimensions of Research Studies

In the best-selling book, The Immortal Life of Henrietta Lacks (Skloot, 2010), the author highlights the true story of an African-American woman who died in 1951 from cervical cancer. What makes her story unique is that prior to her death, cells from her tumor were removed and successfully grown in a petri dish. This was the first time scientists were able to successfully replicate cells outside the body, and it is estimated that billions of Lacks’ cells have been used in medical research. However, Henrietta Lacks was never asked for permission to take a sample and her family was never made aware of the widespread use of her cells. Although the culturing of her cells has been pivotal for advancing research, strong ethical concerns later arose about using these cells without patient or family approval.

This week’s readings describe historical examples of unethical research, such as a study of syphilis among African-American men in which treatment was withheld and a study in which live cancer cells were injected into elderly patients. Today, stricter controls that seek to protect study participants are placed on researchers, but breaches still occur. Careful attention must be given toward preventing unethical behavior. In this Discussion, you explore ethical considerations and issues in research.

To prepare:

Select a current health-related case involving research ethics. (If none come to mind, browse the Internet to familiarize yourself with recent cases.)

As you review the case that you have selected, reflect on the ethical principles discussed in “What Are the Major Ethical Issues in Conducting Research?” article found in this week’s Learning Resources. Which principles were breached in the case you have identified?

By Day 3

Post a description of the case that you selected and the ethical issues involved. Analyze the ethical principles that were breached by the researchers or organizations in your selected case as well as the possible cause of the breach(es). Suggest how the research might have been conducted differently to avoid or minimize the ethical problems. Discuss how research can be done on sensitive issues while still protecting the rights of the research subjects.

Read a selection of your colleagues’ responses.

By Day 6

Respond to at least two of your colleagues on two different days using one or more of the following approaches:

Ask a probing question, substantiated with additional background information, and evidence.

Offer and support an alternative perspective using readings from the classroom or from your own review of the literature in the Walden Library.

Make a suggestion based on additional evidence drawn from readings or after synthesizing multiple postings.

Week 5 discussion

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.Assignment : Evidence-Based Practice
