Title: Doing qualitative research: study design, sampling, data collection


1
Doing qualitative research study design,
sampling, data collection
  • Elizabeth Boyd, PhD
  • EPI 240
  • January 15, 2008

2
Recap Using qualitative methods
  • To interpret, illuminate, illustrate
  • To understand why or how
  • To describe previously unstudied processes or
    situations
  • To learn about subjects who are few or hard to
    reach
  • To brainstorm ideas

3
Research questions - what do you want to
understand?
  • Meaning
  • Context
  • Unanticipated phenomena
  • Process
  • Explanations
  • Opinions
  • Attitudes
  • Understandings
  • Actions

4
Formulating research questions
  • Pub bias example
  • Your examples
  • Common problems
  • Too broad
  • Impossible to find answers or how to
    operationalize
  • Really asking a quantitative question

5
Data collection
  • Based on what you want to know
  • Where do you go to find out?
  • Site selection
  • Who do you ask/observe?
  • Sample
  • What do you ask/do?
  • Data

6
Choosing your site
  • Justification why is this site the best for
    answering your research questions?
  • Naturalistic?
  • Ethnography video
  • Public vs. private settings
  • Neutral?
  • Interviews focus groups

7
Choosing your site
  • Implications
  • Ethical
  • Role as researcher-caregiver
  • Logistic
  • How to gain access?
  • How to gather data?

8
Sampling
  • Who will you include in your study and why?
  • Everyone (ethnography)
  • Sample -- need sampling strategy
  • Random
  • Convenience
  • Purposeful
  • Typical
  • Hetereogenous
  • Extreme cases/comparisons

9
Data collection
  • Once you have identified your site and
    participants, practical matters include
  • Timing -- when to go/how long to stay?
  • Fitting in
  • Establishing relationships -- Who? How? How much?
  • Equipment
  • Recording devices
  • Hand notes
  • Video/digital
  • Impact on participants
  • Cost/transportability/impact

10
Quality in qualitative research
  • Two phases -- data collection and write-up
  • Overall quality credibility
  • Credibility is achieved through depth, clarity,
    nuance

11
Rich and sufficient data
  • Enough background to understand and portray full
    range of persons, processes, settings
  • Detailed description of range of views actions
    -- multiple perspectives
  • Beyond superficial
  • Analytic categories -- complexity
  • Comparisons -- generative or general?
  • Saturation -- stop seeing new cases/instances

12
Bottom Line
  • Regardless of the type of data you are working
    with,
  • Ground ALL observations, analyses in the
    particular details of your data

13
Managing your data
  • Youve interviewed 10 (or 20, or 30, or 100)
    people, now what?
  • Transcription
  • Coding
  • Analysis

14
Transcription
  • Written representation of the interview
  • Types of transcription
  • Cleansed transcript
  • Just the words
  • Jeffersonian transcript

15
The cleansed transcript
  • Dr. E Im deputy editor of Annals of Internal
    Medicine. I was associate editor from 1978 to
    1999, and I was deputy editor from 1999 to 2003.
    My sub-specialty is pulmonary disease which I
    practice every day at the University of
    Pennsylvania. Most of the editors at Annals do
    practice, though not as extensively as I do.

16
Just the words
  • IR So today is March seventh. Im at Annals of
    Internal Medicine and Ill be interviewing Dr.
    P.E. And for the record can you state your name
    and position?
  • DrE Its P.E. Im deputy editor of Annals of
    Internal Medicine.
  • IR Okay. And how long have you been working at
    Annals?
  • DrE Since 1978. Its a long time. I was
    associate editor from 1978 to 1999 and Ive been
    deputy editor from 1999 to 2003.

17
Jeffersonian transcript
  • IR So today is March seventh, Im at Annals of
    Internal Medicine and Ill be interviewing doctor
    Pete Ernest. (0.4) And um for the record can
    you state your name and position?
  • IE Its Pete Ernest, Im deputy editor of
    Annals of Internal Medicine.

  • IE Since nineteen seventy eight. Its a long
    time. I was uh associate editor from nineteen
    seventy eight t nineteen ninety nine,

18
Which transcription method to use?
  • Speed versus detail and accuracy versus cost
  • What are you most interested in learning --
  • Content?
  • Narrative?
  • Interaction?/Context?

19
Assignment
  • If necessary, refine your research questions
  • Describe your sample and data collection protocol
  • Describe how you will prepare your data for
    analysis
  • Be sure to defend your choices!
