Quantitative study:
Qualitative study:

A

2) Epistemology
Quantitative study: researchers are independent from their study subjects and that researchers can control for possible biases in order to make objective measurements
Qualitative study: researchers and study participants are interdependent, and they create knowledge together as they interactively explore subjective topics

21
Q

Method:

A

-In-depth interviews, examining transcript to identify meanings and themes
-researchers may out aside preconceieved ideas about reality in order to be open to new meanings that might be expressed by particpants (Bracketing)

22
Q

Phenomenology Example

A
23
Q

Grounded Theory

A
  • AN inductive reasoning process
  • the use of observations to develop general theories that explain phenomena
    -simultaneous data collection and data anaylysis
    -No predetermined sampling strategy
    -data collection continues unti data saturation (reaching the theory)
    Theoretical sampling
24
Q

Grounded Theory Continued

A
25
Q

Ethnography

A

-systematic study of people and cultures in their natural environments
-an anthropological approach to develop an insider’s view of the way members of a sociocultural group understand their world
-ethnographers often-use participant observation methods to understand a group’s collective experiences, values, beliefs, and behaviours

26
Q

Ethnography COnt

A

Observing participants to understand their beliefs

27
Q

Case study (do not confuse with case report/series)

A

Use of multiple data sources to examine and understand one person, group, or event in detail
* observations
*Interviews
*historic records
sometimes before preparing a case report or a case series (week 5)

28
Q

Case study example

A
29
Q

Mixed method Studies

A

Element of both quantitative and qualitative methods in one single study
* parallel collection of quantitative and qualitative data and then compare the result s and interpret them
*sequential collection of data
*some qualitative studies are mebedded within a quantitative study

30
Q

Collecting Qualitative Data
The main issue

A

Close engagement of researchers with participants
* hard to remain objective
* higher chance of bias
Both a methodological and an ethical issue
Key is transparency

31
Q

In-depth Interview
Semi-structured?
What are the two techniques?

A

-Long (1 or 2) hours interviewing a key informant using open-ended questions
S
Semi-structured: a list of open-ended questions as starting points for eliciting responses from participants
Techniques:
- Probing: prompting interviewees to provide a roe complete or specific response
-Observing and recording: body language, other nonverbal communications

32
Q

Focus Group

A

-small number of people (8-10 individuals with similar backgrounds, experiences, or perspectives) participating for 1 or 2 hours in a moderated discussion
-the facilitator poses questions to the group, keeps the conversation focused on the core discussion items and moving forward at an appropriate pace
* participants and encouraged to interact with one another
-richer responses and clearer opinions
The moderator ensures that everyone has an opportunity to speak and that no one dominates the conversation
-usually are audio- or video-recorded so that complete transcripts can be created

33
Q

Observational Methods

A

Systematic observations of human actions and interactions

34
Q

Naturalistic observation

A

the researcher discreetly observes study subjects in a natural setting, typically without the knowledge of the subjects (covert)

35
Q

Controlled observation

A

study participants are observed in a laboratory setting and know that they are being observed (overt)

36
Q

Participant- observation:

A

a trained investigator seeks to understand a community by engaging with its members and immersing in its practices

37
Q

Field notes:

A

Observation records, interview transcripts, and other documents compiled during the qualitative research process

38
Q

Analyzing Qualitative Data

A
39
Q

Approach
Is inductive:

A

making inferences (identifying patterns, developing theory) based on observations
-flexible and can be in a cycle

40
Q

Quantitative studies is deductive:

A

making logical inferences based on facts or widely-accepted premises (testing theories)
Linear: data collection»analysis»interpretation»reporting

41
Q

Analytic Frameworks: 1) Content Analysis

A

The process of categorizing textual data
1) Systematic CODING the text using labels and categories derived from the text or from existing theories or previous research findings
2) Determine which codes occur most often, and then identification of the most prominent patterns and themes in the text.
Which study design used this analytic framework more?

42
Q

Analytic Frameworks: 2) Constant Comparison

A

A process of collecting data, transcribing interviews, assigning initial codes , identifying categories, identifying themes, and developing a theory
-may include several cycles of data collection, analysis, and additional data collection and analysis
Which study design uses this analytic framework more?

43
Q

Analytic Frameworks 3) Narrative and Discourse Analyses

A

Narrative analysis seeks to understand personal stories
-content of stories, the structure of stories, the themes of stories, or the communication goals of stories
-postmodernism, feminism, or other established philosophies may be applied to help with interpretation of the stories

Discourse analysis uses the tools of linguistics to evaluate the ordinary use of written and spoken language- that is, natural language use

Not common analytic strategies in health research

44
Q

Process Coding
Coding (indexing):
Goal of coding:

A

Coding (indexing) is the use of words or short phrases to briefly summarize the contents, attitudes, processes, or other aspects of each item in a transcript or other qualitative document
Code: a label attached to a word or a phrase
Goal of coding: descriptions of participants characteristics, emotions, values , evaluations , judgments, processes, or actions

45
Q

Process Categorizing

A

grouping related codes into categories
-to identify trends and patterns, look for relationships between codes, and begin to understand multiple layers of meaning

46
Q

Process themes

A

Synthesizing the categories in order to identify the concepts, meanings, and themes that answer the study question
a theme is a concept that encompasses one or several categories

47
Q

Questions about Mental Wellbeing

A
48
Q

Process Theories

A

a theory is a construct that provides a systematic explanation about a phenomenon
-for some studies, a fourth level of coding generates a new theory about the phenomenon
