The Nature of Qualitative Research
Qualitative research is the collection, analysis, and interpretation of comprehensive narrative data in order to gain insights into a particular phenomenon of interest
Useful for describing and answering questions about participants and contexts Objective 1.1
The Nature of Qualitative Research
Purpose of qualitative research
Promote a deep, holistic understanding of a particular phenomenon
Importance of exploring qualitative topics
Provide insight into the complexity of common occurrences Provide specific concrete details to guide understanding in a particular setting Objectives 1.2 and 1.3
The Nature of Qualitative Research
The importance of exploring qualitative topics (continued)
Provide insight into the “local” meanings that activities and practices have for participants Develop a comparative understanding of phenomena as experienced by different participants in different settings Objective 1.3
The Nature of Qualitative Research
Six General Steps
Identify the research topic Review the literature Select the participants Collect data Analyze the data data Report the results
These are the same steps as those used in quantitative research Objectives 2.1 and 2.2
Range of Qualitative Approaches
Nine approaches
Case study
Ethnography
An effort to seek an understanding of a single person or entity An effort to describe and analyze all or part of the the culture of a community by identifying and describing participants’ practices and beliefs
Ethology
An effort to compare several cultures with one another another
Objective 3.2
Range of Qualitative Approaches
Nine approaches (continued)
Ethnomethodology
Grounded theory
An effort to examine people’s understanding of their daily activities An effort to derive theory grounded in the perspectives of the participants
Phenomenology
An effort to understand the meaning of an individual’s individual’s experiences Objective 3.2
Range of Qualitative Approaches
Nine approaches (continued)
Symbolic interaction
Action research research
An effort to seek common understandings that emerge to give meaning to participants’ interactions An effort to seek a solution or improvement to a practical practical problem in the setting in which it is occurring
Historical research
An effort to seek to understand the past by studying documents, relics, and interviews Objective 3.2
Features of Qualitative Approaches
Differences between approaches
Different social contexts are being studied in each approach The participants are selected for different reasons in each approach
Objective 3.1
Features of Qualitative Approaches
Eight unique characteristics
Researchers immerse themselves in the situation si tuation The data reflects the participants’ perspectives perspectives Sources of data are real-world situations or natural contexts Data is narrative in nature Researchers focus on personal interactions with participants Objective 4.1
Features of Qualitative Approaches
Eight unique characteristics (continued)
Researchers avoid early decisions or assumptions about the study Data are analyzed inductively Methods provide clear, detailed information reflecting participants’ voices Objective 4.1
Technical Issues
Validity
The degree to which the qualitative data collected accurately gauges what is being measured Two components
Trustworthiness Understanding Objective 5.1
Technical Issues
Validity
Trustworthiness
Credibility – taking into account all the complexities in the study and addressing problems that are not easily explained Transferability – including descriptive, context-relevant statements so the reader can identify with the setting Dependability – collecting stable data Confirmability – assuring the neutrality and objectivity of the data
Objective 6.1
Technical Issues
Validity
Understanding
Descriptive validity – the factual accuracy of the account Interpretive validity – the meaning attributed to the behaviors or words of the participants Theoretical validity – the explanation of the phenomenon being studied in relation to a theory Evaluative validity – sufficient objectivity in reporting data to avoid bias, preconceived judgments, or evaluations Objective 6.2
Technical Issues
13 strategies to ensure validity
Participate at the study site for a prolonged period of time Use persistent observation Use peer debriefing Collect mechanically recorded data Use member checks Establish structural corroboration/coherence corroboration/coherence Establish referential adequacy Objective 6.3
Technical Issues
13 strategies to ensure validity (cont.)
Collect detailed descriptive data Develop detailed descriptions of the context Overlap methods (i.e., multi-methods) Establish an audit trail Practice triangulation Practice reflexivity Objective 6.3
Technical Issues
Reliability
The consistency with which data measures what is being attempted to be measured over time Qualitative perspective
The reliability of the techniques that are being used to collect data
Reliability is a necessary but not sufficient characteristic – validity is the priority Objectives 7.1 and 7.2
Technical Issues
Generalizability
The applicability of findings to settings and contexts different from the one in which they were obtained Internal-external Internal-external validity issues revisited
A depth of understanding can only be achieved achieved from a few participants in a very limited number of contexts Generalizability is therefore very limited Qualitative researchers are primarily concerned with validity and reliability and to a much lesser extent generalizability Objective 8.1
Technical Issues
General strategies for ensuring the technical merit of a qualitative study
Talk little, listen a lot Record observation accurately Begin writing early Let readers see for themselves Report fully Be candid Seek feedback Write accurately
Ethical Issues
Ethics can be considered in terms of how the researcher treats the participants in the research setting. The nature of qualitative research provides the potential for conflict and harm.
Qualitative research is intimate – there is little distance between the researcher and the participants Qualitative research is open-ended – the nature of the process requires the use of an emergent design as the situation unfolds Objectives 9.1 and 9.2
Ethical Issues
Six guidelines to help avoid ethical problems
Researchers should have an ethical perspective that is close to their personal ethical position Informed consent should take the form of a dialogue that mutually shapes the research and the results
Confidentiality is more complicated even with the use of pseudonyms Consider the use of a video tape to illustrate a point being made Objective 9.4
Ethical Issues
Six guidelines to help avoid ethical problems (cont.)
You should be able able to identify identify broader social principles that are an integral part of who you are as a researcher and a contributing member of the community in which you live. Avoidance of harm morally binds qualitative qualitative researchers to conduct their research in a manner that minimizes potential harm to those involved in the study. Objective 9.4
Ethical Issues
Six guidelines to help avoid ethical problems (cont.)
Even though an action can bring about good results, it is not ethical unless it also conforms to ethical standards such as honesty and justice. The qualitative researcher must remain attentive to the relationships between the researcher and the participants – a relationship that is determined determined by “roles, status, language, and cultural norms.” Objective 9.4
