Q

Theoretical Sampling

Q

What is the preferred sampling method in gorunded theory research and why?

A

Theoretical Sampling - this is because we are constantly using emergent design in grounded theory

Q

What is the sample size usually like in qualitative research

A

there is no explicit formal criteria for sample size as there is no power analysis and size needed - sample size is instead determined by informational needs

Q

When do qualitative researchers know when to stop sampling

A

Via Data Saturation - If you are hearing similar stories and themes over and over you can decide to stop recruiting for the study

So you could end sampling early with fewer sources fi they are rich ones

Q

What is sampling like with Ethnography Tradition

A

Sampling with a “big net” approach - mingling with many members of the culture

Multiple interviews with smaller number of KEY INFORMANTS - but typically involves sampling THINGS as well as people

19
Q

What is sampling like with the Phenomenology Tradition

Study These Flashcards
A

Relies on very SMALL samples (15 or fewer oftentimes)

2 Principles guide sampling: the participant must have experienced the phenomenon of interest and they must eb able to articulate what its like to have lived that experience

May sample some artistic or literary sources as well

20
Q

Which tradition usually has the smallest sample size and why

Study These Flashcards
A

Phenomenology because rich interviews can lead to data saturation faster

21
Q

What is sampling like with the Grounded Theory Tradition

Study These Flashcards
A

Usually 20-30 people

Selection of participants who can best contribute to emerging theory (Usually THEORETICAL SAMPLING) is done

So they have a general notion of who to start with and as things change they recruit new

22
Q

What 3 things should be looked at when critically appraising qualitative sampling plans

Study These Flashcards
A
  1. Appropriateness (does the method of sampling seem right)
  2. Adequacy (Does it provide samples with rich data)
  3. Transferability (Nebulous - am I seeing similarities between study samples)
23
Q

Lots of qualitative data is in the form of ___

Study These Flashcards
A

words (transcripts and audio recording)

24
Q

What is unique about data collection in qualitative studies

Study These Flashcards
A

Data collection methods may change as the study progresses

25
What are the most common methods of data collection in qualitative studies
indepth interviews - and observation (good for ethnographic and some phenomenological)
26
Unstructured Interview
Type of Qual Self Report Technique Totally open ended, conversational, and totally flexible beginnings of data collection This is good since we do not know what we do not know and structured questions will limit information Uses Grand Tour Questions
27
Grand Tour Questions
Questions in Unstructured Interviews involves grand overarching questions followed up with related open ended questions Allows you to follow a tangent or unexpected road of information Usually only start with 3-4 overarching questions
28
Semi Structured Interviews
Type of qualitative self report Data collection similar to unstructured interviews but uses a topic guide for staying on track Can limit some information
29
Focus Group Interviews
Type of qual self report technique Interviews led by a MODERATOR in small groups (5-10 people) The moderator is trained in focus group methods and amages the conversation between people Basically group interviews - they are often recorded and later transcribed
30
Diaries
Type of qualitative self report Source of historical research that provide intimate details of everyday life Can yield unique qualitative information
31
Photo Elicitation
Type of qual self report technique Interview stimulated and guided by photographic images Using photos to guide the interview or having participants take photos to gain information on experiences or insight on the experience
32
Photovoice
Type of photo elicitation where the participants take images themselves and interpret them
33
Qualitative Observation
Unstructured observation in a naturalistic setting including participant observation So the researcher knows they are part of a natrualistic setting so some of their involvement is put into the interpretation of the observation
34
Why is the Hawthorne effect, while still an issue, not as big of an issue in qualitative research than quantitative
Because while it changes behavior it can add some richness that you would not normally get The research just has to keep in mind that some of what they bring to the table affects the participant
35
Why do researchers in qualitative research gather narrative self report data
to develop a construction of a phenomenon consistent with that of the understanding of the participant
36
Making a construction of a phenomenon in qualitative researh requies the research to do what
overcome communicaiton barriers and enhance information flow - get unobstructed flow of info between research and participant
37
What are some of the things to look at during participant observation in qualitative research
physical setting participants activities frequency and duration of activities process outcomes- why it did or didnt happen etc
38
Field Diaries/Notes (Logs)
Records of qual. observations Can be (1) descriptive observational notes or (2) reflective ones The notes should show a reconstructable situation but show research reflecting on what is happening to acknowledge they know in a constructivist paradigm they cannot remove themselves so they should be observing and reflecting on the progress
39
Reflective Notes involve what 3 things
1. Researchers Personal Experiences 2. Reflections 3. Progress in the fields
40
Unstructured observational methods are an excellent methodd for...
capturing many clinical phenomena and behaviors
41
In unstructured observational methods, observers may lose objectivity in sampling, viewing and interpreting observations. Why is this ok?
It can be okay as long as we have measures like multiple researchers to prevent one researcher's emotions from skewing results and we can triangulate some information Researchers should also be aware of the emotional involvement concern and be able to account for it It is ok as long as we maintain that they dont get a myopic view on the situation
42
Success of participant observation in qualitative unstructured observational research depends on...
the observer's observational and interpersonal skills
43
T/F: Sampling in qualitative research is guided more by the desire for rich sources of information than by the need for random selection
True Rationale: Selection of sample members for qualitative research is guided by the desire for information rich sources. The representativeness of the sample is not a key aspect, and random selection is not considered productive
44
T/F: A focus group involves at least 10-15 people
False Rationale: A focus group usually involves interviews with small groups ranging in size from 5-10 people
45
T/F: In qualitative studies observation is unstructured
True Rationale: Observation with qualitative study is unstructured and occurs in naturalistic settings
