Overview of Qualitative Research

What is Qualitative Research?

  • Definition (Creswell, 2013): "Qualitative research begins with assumptions and the use of interpretive/theoretical frameworks that inform the study of research problems addressing the meaning individuals or groups ascribe to a social or human problem. … includes the voices of participants, the reflexivity of the researcher, a complex description and interpretation of the problem, and its contribution to the literature or a call for change."

Main Features of Qualitative Research

  • Data Type: Utilizes words, observations, images instead of numbers.

  • Natural Setting: Focuses on perspectives of people being studied.

  • Researcher Role: The researcher acts as the key instrument in data collection.

  • Data Richness: Aims for rich, in-depth data from small samples.

  • Methodological Differences: Contrasts with quantitative research in epistemology and methodology.

  • Non-hypothesis Testing: More open-ended and exploratory than hypothesis-based research.

When to Use Qualitative Approaches

  • Situations: Applicable when little is known about a phenomenon, such as:

    • Health perceptions.

    • Decision-making in healthcare.

    • Cultural influences on change.

    • Activities in health systems that defy quantitative measurement.

    • Healthcare providers' behaviours within care contexts.

    • Clinical decision-making regarding feasibility, appropriateness, and meaningfulness.

    • Identify the problem.

    • Review existing literature.

    • Formulate variables.

  • Phase 2: Design the Study

    • Select research design.

    • Identify sample and setting.

    • Choose data collection methods.

    • Evaluate instrument quality.

  • Phase 3: Conduct the Study

    • Obtain approval for human subjects research.

    • Recruit subjects.

    • Collect data.

  • Phase 4: Analyze the Study

    • Describe the sample.

    • Address research questions.

    • Interpret the results.

  • Phase 5: Use the Study

    • Recommend further research.

    • State implications for nursing practice.

    • Disseminate results.

Researcher’s Role and Reflexivity

  • Experience with Participants: Researcher must document experiences with participants that may impact interpretations.

  • Ethical Considerations: Ethical issues may arise from personal connections or biases.

  • Reflexivity Importance: Comment on how personal experiences shape research interpretations.

Qualitative Research Design

  • Analytic Frameworks: Include narrative study, phenomenology, grounded theory, ethnography, and case study.

    • Specific frameworks guide data collection and analysis.

    • Limited variability in application; popularized in specific fields.

  • Descriptive Methods: Based on participants' everyday language, with minimum theoretical interpretation, focusing on theme cataloging.

Qualitative Methodologies

Phenomenology

  • Definition: “Phenomenology is both a philosophy and a research method aiming to describe experiences as they are lived.” (Burns & Grove, 1997)

  • Purpose: Capture the ‘lived experience’ of participants.

  • Research Questions:

    • "What is the nature of …?"

    • "What is it like to experience …?"

Ethnography

  • Definition: Developed by anthropologists, this method aims to describe a culture or part of it.

  • Purpose: Aimed at learning from, rather than studying people (Powers & Knapp, 1995).

  • Focus: Understanding the customs and values of social groups.

Grounded Theory

  • Definition: “Grounded theory is a qualitative research approach used to explore social processes in interactions.” (Streubert & Carpenter, 1999)

  • Application: Develop theoretical explanations for socially constructed events and generate hypotheses for further research.

Action Research

  • Definition: A method involving actions to improve practice, while studying effects systematically (Streubert & Carpenter, 1999).

  • Focus: Real-world events aimed at collaborative inquiry and practical improvement.

  • Theoretical Foundation: Underpinned by social critical theory (Lewin, 1946).

Summary of Qualitative Research Methods

  • Descriptive: Exploratory; rich narrative data.

  • Phenomenology: Focus on lived experience.

  • Grounded Theory: Systematic procedures to build theory.

  • Ethnography: Cultural descriptions.

  • Action Research: Collaborative projects enhancing practice.

Data Collection Techniques

  • Direct Methods:

    • In-depth Interviews: Face-to-face, phone, or online.

    • Focus Group Interviews: Gather perspectives in groups.

    • Observation: Interact and observe in natural settings.

    • Diaries: Personal reflections maintained over time.

  • Indirect Methods:

    • Audiovisual: Use of media to gather data.

    • Document Reviews: Analyzing existing documents related to the study.

The Human Relationship in Qualitative Research

  • Importance of Rapport: Key element across qualitative research methods.

  • Types of Interviews:

    • Structured: Comparable but limited flexibility.

    • Semi-Structured: More flexible, but potential bias due to researcher influence.

    • Unstructured: Allows in-depth responses, though difficult to compare.

Data Recording Procedures

  • Development of protocols to ensure consistency in data collection.

  • Importance of preparing guides with questions, probes, and closing instructions.

  • Aim: Maintain participant relationships, avoiding power imbalances.

Observational Techniques

  • Data Gathering: Collect information through observation in natural settings including interactions.

  • Protocols: Develop systematic approaches for recording observations, including demographic information and settings.

Document Review Types

  • Forms of Documents:

    • Historical documents, life histories, diaries, photographs, official records, patient stories, and other qualitative/quantitative sources.

Data Analysis Procedures

  • Main Steps:

    • Segment and disassemble data, then reassemble after analysis.

    • Ongoing process alongside data collection.

    • Develop themes and subthemes from dense information.

Coding Process Factors

  • Four steps include:

    1. Data immersion.

    2. Coding.

    3. Category creation.

    4. Theme identification.

Thematic Analysis Steps (Braun & Clarke, 2006)

  • Familiarization with data.

  • Generating initial codes.

  • Searching for themes.

  • Reviewing and finalizing themes.

  • Report production.

Managing Qualitative Data

  • Manual Analysis: Use of highlighters and colored pens.

  • Software Utilization: Tools like MAXqda®, Atlas.ti®, NVivo® for organization and analysis.

Interpretation in Qualitative Research

  • Summarizing findings, comparing to literature

  • Personal interpretation, limitations, and future research recommendations.

Trustworthiness in Qualitative Research

  • Key Components:

    • Credibility: Trust in findings reflecting participants’ perspectives.

    • Transferability: Findings applicable to other contexts.

    • Dependability: Consistency in research methods.

    • Confirmability: Findings can be corroborated by others.

Validity vs Reliability

  • Validity: Assess if findings are accurate and reflective of participants' perspectives.

  • Reliability: Consistency and reproducibility of the research process.

Triangulation Types

  • Data Triangulation: Utilizes multiple data sources over time, space, and person.

  • Method Triangulation: Employs multiple data collection methods.

  • Investigator Triangulation: Involves multiple researchers for analysis and interpretation.

Enhancing Trustworthiness

  • Strategies to enhance credibility, transferability, dependability, and confirmability documented as per detailed plans.

Activities

  • Develop a Qualitative Research Study Plan: Consider research questions, sampling, recruitment, and data collection methods promoting trustworthiness.

Qualitative Research Advantages and Disadvantages

  • Advantages:

    • Useful for in-depth exploration, flexible approaches, direct information sourcing.

  • Disadvantages:

    • Potential biases, challenges in analysis and reproduction, time-consuming, and rapport building.
