Qualitative Research Methods: Collection and analysis of non-numerical data

Question 1

Define research

Answer 1

Research is a systematic process of inquiry and exploration that aims to generate new knowledge and understanding about a specific topic or field of study

It involves the collection, analysis, and interpretation of data (which could be qualitative, quantitative, or both) to answer a specific question or test a hypothesis

In the context of biomedical science, research might involve laboratory experiments, clinical trials, observational studies, or qualitative studies

Question 2

Describe how qualitative research and quantitative research methods differ in 1) data collection 2) analysis 3) theory development

Answer 2

Data Collection:

Qualitative Research:

• Involves collecting non-numerical data that captures people’s characteristics, meanings, concepts, definitions, characteristics, metaphors, symbols, and description of things
• This is typically done through methods such as interviews, focus groups, ethnographic research, content/document analysis, participant observation, or diaries/stories

Quantitative Research:

• Focuses on collecting numerical data that can be transformed into usable statistics
• Data collection methods commonly include surveys, structured observations, or experimental studies
• usually collected in a structured manner with standardised tools to ensure reproducibility

Analysis:

Qualitative Research:

• Analysis often involves identifying themes or categories, seeking patterns, or developing an understanding of the meaning of the data
• Techniques used can include thematic analysis, discourse analysis, narrative analysis, grounded theory, or interpretative phenomenological analysis
• The emphasis is on understanding the depth and complexity of the data

Quantitative Research:

• Analysis involves statistical techniques to analyze the data, ranging from simple descriptive statistics (such as means and standard deviations) to more complex inferential statistics (such as t-tests, chi-square tests, or regression analysis)
• The focus is on measuring variables, identifying relationships between them, and determining cause and effect

Theory Development:

Qualitative Research:

• Often associated with inductive reasoning where new theories are generated from the data (grounded theory)
• The aim is to understand phenomena in context-specific settings and the interpretation made by people in relation to those phenomena

Quantitative Research:

• Often associated with deductive reasoning where data is collected to evaluate or test a pre-existing theory
• The researcher begins with a hypothesis, collects data to test it, and then examines whether the data supports or contradicts the hypothesis

Question 3

Describe how qualitative research is performed

Question 4

Describe the benefits of qualitative research in healthcare

Answer 4

1) Understanding Patient Perspectives and Experiences: Qualitative research can provide insights into how patients perceive their health, illness, treatment, and care, giving healthcare providers a better understanding of the patient’s experience. It can provide valuable feedback on the acceptability and perceived effectiveness of treatments.

2) Developing Patient-Centered Care: By understanding the needs, values, and preferences of patients, qualitative research can inform the development of patient-centered care approaches, thereby improving patient satisfaction and outcomes.

3) Informing Health Policy: Qualitative research can illuminate the social, cultural, and economic contexts that influence health behaviors and outcomes, thus helping to shape health policies that are sensitive to these contexts.

4) Exploring Provider Perspectives: Qualitative research can also provide insights into the experiences and perspectives of healthcare providers, helping to identify factors that impact job satisfaction, burnout, or the quality of care provided.

5) Enhancing Quantitative Findings: Qualitative research can complement and enrich quantitative research by explaining unexpected results, providing context, or generating hypotheses.

6) Improving Health Services: Qualitative research can help identify gaps in healthcare services, barriers to care, and opportunities for improvement by capturing detailed experiences and observations from both patients and providers.

7) Understanding Health Behaviors: Qualitative research is crucial for exploring why people engage in certain health behaviors, including adherence to medication, dietary habits, exercise routines, and more.

8) Developing and Refining Interventions: Qualitative methods can be used in the initial stages of intervention development, to understand the needs of the target population, or to refine interventions based on participant feedback.
