WHAT IS QUALITATIVE RESEARCH?
Any type of research that produces findings not arrived by statistical procedures or other means of quantification.
Refers to research about:Person’s livesLived experiencesBehaviors, emotions, feelingsOrganizational functionSocial movementsCultural phenomena
Strauss & Corbin, 1998

QUALITATIVE RESEARCH
GOALS: Explore, discover, understand, describe
TYPES OF RESEARCH QUESTIONS:Why?How?
![Page 9: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/9.jpg)

CHARACTERISTICS
Starts with general question or problem
Usually no pre-defined hypothesis
Uses a small, purposeful sample (not random)
Often done in naturalistic settings
Creswell, 2009
![Page 10: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/10.jpg)
10
CHARACTERISTICS (cont.)
In-depth analysis
Present results descriptively
Focus on participants’ meanings; holistic account
Emphasize personal experiences and interpretation over quantification
Interpretive; Researcher as key instrument- awareness of own orientations, biases, experiences
![Page 11: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/11.jpg)
11USE QUALITATIVE METHODS…
To explore a topic/population that has previously not been studied
To gain a more holistic, contextualized understanding
To gain insight into possible causal mechanisms
To study behavior in a natural setting (gangs, homelessness, drug use, etc.)
![Page 12: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/12.jpg)
12
USE QUALITATIVE METHODS…
To understand local terms, meaning
To develop survey instruments
To explore quantitative findings
To test feasibility
To test standardized measurements or instruments on different cultures, populations

THE PROCESS
Systematic process!
STEP 1: Decide on sampling procedure
STEP 2: Decide on the specific methods
STEP 3: Decide on how to analyze data
![Page 20: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/20.jpg)
20
HOW TO DESIGN A STUDY…
STEP 1: DECIDE ON A SAMPLING PROCEDURE
How much is known about this topic and population
Clear eligibility/exclusion criteria
Homogeneity of the population
How to gain access to this population
Your resources
![Page 21: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/21.jpg)
21
APPROPRIATE SAMPLE DESIGN DEPENDS ON…
Degree of accuracy required
Range of possible experiences (homogeneity of target group)
Need for statistical analysis
Difficulty reaching your population
Ethical issues
Resources (i.e. time / money)
![Page 22: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/22.jpg)
22
SAMPLING
Adequacy of sample depends not so much on the number of cases
Need for smaller but focused samples rather than large, random samples
Who will you learn the most from?
Depends on the proper specification of the cases to be analyzed
![Page 23: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/23.jpg)
23
SAMPLE SIZE
Required size (n) is often unknown
Recent guidance- n=30 is large enough sample (Dworkin, 2012)
Maximize possibility that all perspectives (positive and negative cases) have been explored
Redundancy in information is often a sign that the sample size is adequate -“saturation point” (Morse, 1995)
![Page 24: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/24.jpg)
24
PURPOSEFUL SAMPLING
Non-probability or non-random sampling
Aim is not statistical representativeness but to gain access to the full range of views, perspectives, themes in the population
Used when there is a limited number of individuals who have the relevant information
Sometimes the only meaningful way to investigate
![Page 25: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/25.jpg)
25
PURPOSEFUL SAMPLING
Select cases rich in information with in-depth understanding
Choose subjects who are in the best position to provide data
“Maximum Variation”
![Page 26: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/26.jpg)
26
PURPOSEFUL SAMPLING
Examples: Snowball Quota Stratified Convenience Homogenous Typical case vs. extreme/deviant/critical case Maximum variation
Patton, 1990
![Page 27: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/27.jpg)
27
PURPOSEFUL SAMPLING-EXAMPLES
Snowball sampling Starting with a small group and asking for further contacts Useful for sensitive topics
Quota sampling Population is stratified and numbers within strata are decided Contacts are made until quotas are full Quotas can be proportional or non-proportional to the population
Confirming or disconfirming cases Other examples to confirm research
Criterion sampling all meet pre-determined criterion--- ex: all dropped out of school,
all in Iraq war
![Page 28: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/28.jpg)
28
PURPOSEFUL SAMPLING-EXAMPLES
Convenience sampling e.g., interviews on the street; simply asking for
volunteers; using clients in clinical or business setting quick, convenient, less expensive not generalizable at all Sometimes only way to reach population
Stratified purposeful sampling Need to stratify in order to make generalizations
about comparisons between groups Each strata will be homogeneous
![Page 29: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/29.jpg)
29SAMPLING EXAMPLES
Sexual practices among men on the down low
Women who use cocaine and who have children under age 5
Why some immigrant Asian women do not seek pre-natal care
Age at first sex among Latino men
Stigma among Mexican parents of children who have cleft lip or palate
![Page 30: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/30.jpg)

HOW TO DESIGN A STUDY…
STEP 2: DECIDE ON A METHOD
How detailed you need the results
Potential biases
Your time, $$ and resources
![Page 31: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/31.jpg)
31
METHODS
Depend on research question & theoretical and philosophical framework
Examples of methods:Documentary ResearchParticipant ObservationInterviewsFocus GroupsCase StudiesOral HistoriesObservationsPhotovoice
![Page 32: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/32.jpg)
32
SELF-REFLEXIVITY
Objectivity is not possible (not required)
Acknowledge your framework, experience, perspective
Researcher influences process from the very beginning all the way through (research question)
Requires self-awareness, transparency
Convince the reader that the researcher(s) is sufficiently knowledgeable and will produce trustworthy results
![Page 33: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/33.jpg)
33
RELIABILITY & VALIDITY
Instead, think of:TrustworthinessApplicabilityRespectAuthenticityFairnessCredibilityMeaning in-contextConsistency
![Page 34: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/34.jpg)
34
STRATEGIES TO INCREASE TRUSTWORTHINESS
Detailed description of methods
Continuous checking for representativeness of data and fit between coding categories and data
Multiple members of team for analysis
![Page 35: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/35.jpg)
35
STRATEGIES TO INCREASE TRUSTWORTHINESS
Prolonged contact with informants
Continuous validation of data (member checks)
Self-reflexivity; transparency/competence of researcher
Triangulation
![Page 36: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/36.jpg)
36
Multiple data sources
Multiple kinds of data
Multiple data collection strategies
Subjects(data sources)
Data collection strategies
Kinds of data
TRIANGULATION
![Page 37: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/37.jpg)
37
A WORD ABOUT FOCUS GROUPS
Depends on research question and population
Focus groups not appropriate for sensitive topics
Group dynamics may influence process
Logistically difficult
Often no savings for time & $
![Page 38: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/38.jpg)
38
IRB ISSUES
You should have a qualitative expert help you write the study protocol (methods) and the IRB application
You will need documents such as: Question guides Screening scripts Recruitment materials
![Page 39: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/39.jpg)

HOW TO DESIGN A STUDY…
STEP 3: DECIDE ON DATA ANALYSIS PLAN
Analysis methods vary
Usually based on looking for patterns, themes, linkages between them
Represent people through and in their own words (Miles & Huberman, 1994)
Examples: content analysis, grounded theory
![Page 41: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/41.jpg)
41
DATA ANALYSIS
Selecting, focusing, simplifying & transforming
Not linear; circular; iterative process
Often occurs simultaneously with data collection
Multiple readings of data
Examination of patterns/themes
![Page 42: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/42.jpg)
42
DATA ANALYSIS
All analytical choices (which codes, quotations to use)
Use of quotes, examples; usually not quantifications
Coding, summaries, clusters: a final report
Miles & Huberman, 1994
![Page 43: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/43.jpg)

![Page 44: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/44.jpg)
44
DATA ANALYSIS SOFTWARE
Software such as Atlas.ti, Envivo, Nudist helps organize
Does not do the analysis for you
![Page 45: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/45.jpg)
45
ESTIMATING TIME FOR ANALYSIS
Depends on if you are audio-taping, transcribing (and translating from another language) Getting the transcripts can take TIME
Takes much more time to do the analysis- at least 2 hours of analysis for every hour of interview
Should be analyzed by multiple members of team, and validated by member of the target group
![Page 46: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/46.jpg)
46
TRANSCRIPTION?
The need to transcribe depends on how detailed you want the data to be
If rich, detailed quotes will be helpful to illustrate a complex process, consider transcription
Sometimes you can audiotape and review tapes in order to write notes and come up with major themes without nuanced, contextual quotes
![Page 47: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/47.jpg)
47
TRANSCRIPTION SERVICES
Professional transcription services
Estimate about 60-90 mins for interviews & focus groups
$75-90 per hour of audiotape
Assumes you have clear audio and only two English speakers More speakers or foreign language= higher cost
![Page 48: DESIGNING QUALITATIVE RESEARCH](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816661550346895dd9eb84/html5/thumbnails/48.jpg)
