abstractions of human characteristics (like pain, fatigue, obesity)
In a qualitative study = phenomena
2
Q
construct
A
abstraction inferred from situations or behaviors - deliverable invented or constructed
I.e. self care
Construct = more complex abstraction than a concept

- research with roots in sociology that seeks to describe and understand the key social psychological processes that occur in social settings
- seek to understand actions by focusing on the main concern or problem that the individual’s behavior is designed to address
Focus on developing social experience
9
Q

A
provides a framework for studying partners, lifeways and experiences of a defined cultural group
anthropology
11
Q
characteristics of good research questions - 3
A
- identifies the variables
- specifies populations to be studied
- implies possibility of empirical testing
12
Q
conceptual definition
A
presents the abstract or theoretical meaning of concepts under study
I.e. pain - discomfort, uncomfortable feeling
*can be an end product in qual studies
13

specifies what the researcher must do to measure the concept and collect needed info
I.e. for measuring anxiety, tools, scales
14
Q
phases of quantitative study (5)
A
- conceptual phase (formulating the problem)

15
Q
hypothesis
A
prediction about relationship b/w variables
16
Q
null hypothesis

statistical hypotheses: state that there is no relationship between IV and DV
I.e. patients age is unrelated to their risk of falling
17
Q
characteristics of good hypotheses (3)
A
- states variable and population
- identifies the predicted relationship: converts question into a declarative statement, predicts relationship b/w variables
- is testable
18
Q
Directional hypothesis
A
one that specifies not only the existence but the expected direction of the relationship b/w variables
I.e. older patients are more likely to fall than younger patients
19
Q
nondirectional hypothesis
A
does not state the direction of the relationship
I.e. there is a relationship b/w age of patient and risk of falling
20
Q
statistical significance
A
supports inferences that a hypothesis probably correct or not
means findings are probably reliable and replicable with a new sample
21
Q
level of significance (p < 0.05)
A
index of how probable it is that the findings are reliable
.05 level = only 5 times out of 100 would the result be spurious = 95 times out of 100, similar results would be obtained in a new sample

55
covert data collection
collection of data without participants knowledge and consent - can happen if a researcher wanted to observe people’s behavior in real world settings and worried that doing so openly would affect behavior of interest
can be acceptable if risk are negligible and participants right to privacy hasn’t been violated
56
deception
involves deliberately withholding information about the study or providing participants with false information
57
implied consent
when written consent is not obtained because the participants completes a questionnaire or something similar that reflects consent to participate

3. Good if you are not in that population and you don’t understand it
60
emergent design
takes shape as qualitative studies / researchers make ongoing decisions reflecting what they have learned
Based on participants realities and viewpoints

74
constant comparison (grounded theory)
categories elicited from the data are constantly compared with data obtained earlier so that the commonalities and variations can be determined
Once researcher starts to get data and interview people → analyze early on and compare to what participants are saying and start to understand data pattern - compare data pattern and interviews
Where design might change (emergent design)
75
descriptive qualitative studies
qualitative studies that do not have a formal name

77
Participatory action research
-Based on a recognition that the production of knowledge can be political and can be used to exert power
-Action researchers typically work w/ groups or communities that are vulnerable
-Researchers and participants collaborate in defining the problem, selecting the research methods and analyze the data, decide on use to which findings are put
aim = knowledge, action and consciousness-raising

Ethnographic are unstructured
99
semi structured interviews
- Know what they want to ask but cannot predict what answers will be
- Researchers prepare a written topic guide to be covered w/ each participant
- Encourage participants to talk freely about all topics on the guide and tell stories on their own
100
focus groups

130
grounded theory analysis : constant comparison
core feature in all grounded theory analyses
Involves a comparison of elements present in one data source (i.e. in one interview) with those in another to determine if they are similar
131
grounded theory: open coding
used in first stage of the constant comparative analysis - captures what is going on in the data

138
are all BSPs core variables?
yes but not vice versa
139
theoretical coding: when does it begin and what is it?
begins while selective coding is still in progress - helps grounded theories to weave the broken pieces of data back together
Connect categories and constructs that relate to the core category
140
ethnography analysis: domain analysis
domain = units of cultural knowledge, broad categories that encompass smaller ones
Identify relational patterns among the terms in the domain that are used by members of the culture
141
ethnography: taxonomic analysis
Ethnographer decides how many domains the analysis will encompass
Taxonomy = system of classifying and organizing terms - developed to illustrate the internal organization of a domain and the relationship among the subcategories of the domain

ethnography: componential analysis
Ethnographer analyzes data for similarities and differences among cultural terms in the domain
143
ethnography: theme analysis
cultural themes are uncovered, discovery of cultural meaning

- Emerges when it conveys the feeling tone of participants lives as they are lived
152
ways to enhance quality: prolonged engagement
investment of sufficient time collecting data to have an in depth understanding of the people under study, to test for misinformation and to ensure saturation of key categories
Essential for building trust w/ informants
153
ways to enhance quality/credibility: Persistent observation
concerns the salience of the data being gathered and recorded
Refers to researcher’s focus on the characteristics or aspects of a situation or a conversation that are relevant to the phenomena being studied
154
triangulation
refers to the use of multiple referents to draw conclusions about what constitutes the trust
155
time triangulation
involves collecting data on the same phenomenon multiple times
Can involve gathering data at different times of the day or at different times in the year

using multiple methods of data collection about the same phenomenon
159
peer debriefing
involves sessions w/ peers to review and explore various aspects of the inquiry
160
member check
researchers provide feedback to participants about the study - including emerging interpretations and elicit participants reactions
Helps establish credibility
Participants realities should match researchers understanding
Can be an ongoing process during data collection
can ask participants (individually or focus group) to confirm accuracy of verbatim transcripts or review analyses of data
161
disconfirming cases
examples that do not fit and challenge researcher's interactions
162
how to enhance dependability (reliability)
replicate findings
| team coding

165
when does ethnographic data analysis begin
when researcher steps into the field
166
incubation
process of living the data, process in which researchers must try to understand the data’s meaning, find essential patterns and draw conclusions
