Content Requirements:
You will select one research report with a qualitative design and one with quantitative design and answer the following questions regarding the following categories:
Discuss what is meant by the term Qualitative Research
Briefly, describe the characteristics of qualitative research and identify nursing issues/phenomena that lend themselves to a qualitative research approach.
Compare and contrast three different qualitative research methodologies.
Briefly, discuss the strengths and weaknesses of qualitative research evidence for informing nursing practice.
Communicate how this research design used in research.
The study, sampling, data collection, analysis, rigor, findings and limitations
Identify the purpose of the study.
Briefly, describe the design of the study and explain why you think it is either appropriate or inappropriate to meet the purpose.
Identify ethical issues related to the study and how they were/were not addressed.
Identify the sampling method and recruitment strategy that was used.
Discuss whether sampling and recruitment were appropriate to the aims of the research.
Identify the data collection method(s) and discuss whether the method(s) is/are appropriate to the aims of the study.
Identify how the data was analyzed and discuss whether the method(s) of analysis is/are appropriate to the aims of the study.
Identify four (4) criteria by which the rigor of a qualitative project can be judged.
Discuss the rigor of this study using the four criteria.
Briefly, describe the findings of the study and identify any limitations.

- Comparing Qualitative Methodologies:
| Methodology |
Description |
Strengths |
Weaknesses |
| Phenomenology |
Explores the lived experience of a phenomenon. |
Rich, detailed understanding of participants' experiences. |
Limited generalizability, subjectivity of researcher interpretation. |
| Grounded Theory |
Develops a theory based on data collected from participants. |
Generates new theoretical frameworks, identifies emerging concepts. |
Time-consuming data collection and analysis, potential for researcher bias. |
| Ethnography |
Studies a culture or group in their natural setting. |
Provides holistic understanding of cultural practices and norms. |
Highly time-intensive, potential for researcher bias in interpretation. |

- Strengths and Weaknesses of Qualitative Evidence:
Strengths:
- Offers rich insights into participants' perspectives.
- Useful for exploring complex and under-researched topics.
Weaknesses:
- Limited generalizability due to small sample sizes.
- Subjectivity of researcher interpretation.
Communicating How Qualitative Research Informs Nursing Practice:
Findings from qualitative research can inform the development of interventions, improve communication strategies, and enhance patient-centered care.
Critically Appraising a Specific Qualitative Research Report:
- Purpose of the Study: Identify the research question(s) and the overall aim of the study.
- Study Design: Analyze the chosen qualitative methodology (e.g., phenomenology, grounded theory). Is it appropriate to answer the research question?
- Ethical Issues: Were informed consent procedures followed? How were confidentiality and anonymity ensured?
- Sampling and Recruitment: Describe the sampling method (e.g., purposive, snowball) and recruitment strategy. Were these appropriate for the study aims?
- Data Collection: Identify the data collection methods (e.g., interviews, focus groups) and assess their suitability for the research question.
- Data Analysis: Discuss how the data was analyzed (e.g., thematic analysis) and whether it aligns with the chosen methodology.
- Rigor: Evaluate the study's trustworthiness using criteria like credibility, dependability, confirmability, and transferability.
- Findings and Limitations: Summarize the key results of the study and identify any limitations (e.g., small sample size).
By following this framework, you can critically analyze both qualitative and quantitative research reports you encounter.
