The perception of beingcured from leprosy
• From the leprosy specialistTreatment completed Infection eradicated

The essence of qualitative research
• Inquiry process of understanding• Based upon distinct methodological
traditions of inquiry that explore a social or human problem
The place of qualitative research

The qualitative researcher
• Builds a complex, holistic picture• Analyzes words• Reports detailed views of informants• Conducts the study in a natural setting
The place of qualitative research

Why use qualitative methods?
• Bridge the gap between: The public health professionals The population that is supposed to benefit
from their work• Who are these people we are working for?
• Get the perspective of the local people The first information can be misinterpreted More information is needed for it to become
intelligible
The place of qualitative research
![Page 8: Introduction to qualitative research methods India FETP.](https://reader036.fdocuments.in/reader036/viewer/2022062300/56649e4e5503460f94b4586f/html5/thumbnails/8.jpg)
When to use qualitative methods?
• Need to explore and explain behaviours Explain rather than describing
• Subject matter is unfamiliar or insufficiently researched Mapping issues
• Suitable vocabulary is not available to communicate with respondents
The place of qualitative research
![Page 9: Introduction to qualitative research methods India FETP.](https://reader036.fdocuments.in/reader036/viewer/2022062300/56649e4e5503460f94b4586f/html5/thumbnails/9.jpg)
What qualitative methods can bring?
• Identify health determinants Underlying behaviours Attitudes Perceptions
• Explain social and programmatic impediment to: Informed choices Use of services
• Shed light on the success of intervention• Facilitate understanding of policy, social and
legal context in which decisions are made
The place of qualitative research

Advantages of qualitative methods
• Flexible• Encourage discoveries• Stimulate more investigation of the
unexpected
The place of qualitative research

Qualitative methods do not replace quantitative research
• Address different questions• Qualitative methods may be in
important input to quantitative research
• Parallel source of distinct, rich and pertinent information
Qualitative versus quantitative
![Page 12: Introduction to qualitative research methods India FETP.](https://reader036.fdocuments.in/reader036/viewer/2022062300/56649e4e5503460f94b4586f/html5/thumbnails/12.jpg)
A source of added value
Qualitative research
Quantitative research
Include in a single design
Qualitative versus quantitative
![Page 13: Introduction to qualitative research methods India FETP.](https://reader036.fdocuments.in/reader036/viewer/2022062300/56649e4e5503460f94b4586f/html5/thumbnails/13.jpg)
Possible sequence in qualitative and quantitative research
1. Qualitative research methods• Sort out / identify issues or factors
2. Quantitative research methods• Measure the frequency of key issues /
factors
Qualitative versus quantitative
![Page 14: Introduction to qualitative research methods India FETP.](https://reader036.fdocuments.in/reader036/viewer/2022062300/56649e4e5503460f94b4586f/html5/thumbnails/14.jpg)
Traditional questions in qualitative methods
• Examples: Why do people behave the way they do? Why are things the way they are?
• The “how many” of the epidemiologist is replaced by “why”
Qualitative versus quantitative
![Page 15: Introduction to qualitative research methods India FETP.](https://reader036.fdocuments.in/reader036/viewer/2022062300/56649e4e5503460f94b4586f/html5/thumbnails/15.jpg)
Deductive versus inductive processes
• Deductive process in qualitative studies(e.g., Einstein) Begins with theory Examines hypothetical relationships within it
• Inductive process in quantitative studies(e.g., Newton) Begins with observations Open questions towards more general
conclusionsQualitative versus quantitative
![Page 16: Introduction to qualitative research methods India FETP.](https://reader036.fdocuments.in/reader036/viewer/2022062300/56649e4e5503460f94b4586f/html5/thumbnails/16.jpg)
Criteria to judge the quality of findings in quantitative and
qualitative researchQuantitative studies
• Accuracy• Reliability• Freedom from bias
Qualitative studies• Neutrality• Uniformity• Objectivity• Replicability
Qualitative versus quantitative
![Page 17: Introduction to qualitative research methods India FETP.](https://reader036.fdocuments.in/reader036/viewer/2022062300/56649e4e5503460f94b4586f/html5/thumbnails/17.jpg)
Emphasis of quantitative and qualitative studies
Quantitative studies• Consistent
operational definitions
• Precisely worded questions
• Statistical analysis
The formulation of questions in measurable terms limits the scope
Qualitative studies• Objectivity• Expression of
findings: Measurable outcomes Relationship

Emic versus Etic perspectives *
Emic Etic
Methods •In depth interview •Observation
Aims •How do respondents define and label things
•Describe and explain patterns of behaviours
Explanations of behaviours
•People’s idea systems
•Impersonal factors•Material conditions
Cross cultural generalizations
•Require conversion in abstract inter-cultural categories
•Application of the same observation method to different cultures
* Neologisms coming from “phonetic” and “phonemic”

Sorting observations and experiences as domains: Free listing
and pile sorting• Free listing
Participants are asked to make lists of all instances of the same phenomenon
Transfer to cards
• Pile sorting Sorting of the cards by piles according to
own criteria and labels
