Q

systematic

A

The selection of sample members such that every #th person or element in a sampling frame is chosen.

o The population is divided by the size of the desired sample to obtain the sampling interval (the fixed distance between selected cases).

o Systematic sampling done in this manner is essentially the same as simple random sampling and is often convenient

Q

quota sampling

A

A nonrandom sampling method in which “quotas” for certain subgroups, based on sample characteristics, are established to increase the representativeness of the sample

o Researchers identify population strata and figure out how many people are needed from each stratum

o Quota sampling is similar to convenience sampling: Participants are a convenience sample from each stratum

Q

facial validity

A

Refers to whether the instrument looks like it is measuring the target construct.

o Not considered good evidence of validity

o Helpful for a measure to have face validity if other types of validity have also been demonstrated

Q

grounded theory types

A

Develops middle range theories

o Constant comparison is used: procedure to develop and refine theoretical relevant concepts and categories

o New data collected compared ongoing to previous data collected

o In-depth interviews & participant interviews for data collection

o Constructivist grounded theory: the data collected and analyzed are acknowledged to be constructed from shared experiences and relationships between researcher and participant

importance of research
Validates knowledge o Refines knowledge o Generates knowledge
26
intuition
Gut feeling; Insite that can’t be explained logically
27
Longitudinal design challenges
Collecting data multiple times over a certain length of time o Useful to study changes over time o Helpful to establish sequence of events o Must decide data points and time intervals between o Challenge is attrition
28
major parts of the research report
``` title and abstract intro method section results discussion references ```
29
nature of qualitative studies
Investigating a phenomena using rich narrative material. o Goal: Develop rich understanding of phenomena o Almost always nonexperimental o Do not conceptualize as having dependent and independent variables o Blinding rarely used o Typically, do not compare groups
30
PICO components and identification in a questio
P- patient population/disease o I- intervention o C- comparison o O- Outcomes
31
primary sources
Written by person who generated ideas/conducted the research o PREFERRED source
32
primary sources can be
§ Qualitative, quantitative, or mixed method research articles § Systematic review § Clinical practice guideline
33
Probability sampling characteristics
Involves random selection of elements from a population. o Each element in the population has an equal, independent chance of being selected
34
Qualitative methodology types
``` ethnography phenomenology grounded theory historical case studies narrative analysis critical theory feminist research Participatory action research ```
35
ethnography
Description and interpretation of culture & cultural behavior § Extensive fieldwork (time consuming) § Purpose: seek to learn from rather than study § -emic & -etic perspectives
36
info sought rhoguh ethnography
Cultural behavior § Cultural artifacts § Cultural speech
37
phenomenology
Main data source is in-depth conversations § Key themes
38
2 main types of phenomenology
descriptive | interpretive
39
descriptive
Depicts “things” as people experience them: § Eclectic design § In-depth collection of qualitative data § No traditional qualitative roots § Content analysis for data interpretation
40
interpretive
Rely on in depth interviews · May augment understandings § Lived experience and interpretive process § Goals: · To enter another’s word & discover the understandings.
41
grounded theory
Develops middle range theories § Identify main problem and offer resolution § Constant comparison is used · New data collected compared ongoing to previous data collected § In-depth interviews & participant interviews for data collection
42
historical
Systematic collection & critical evaluation of data related to past events/occurrences § Usually interpretive-describe what, how, & why § Primarily relies on written records:
43
case studies
Single or Small number of entities with in-depth review § Understand the “why” rather than the “what” § Strength/Weakness
44
narrative analysis
The story is the form of inquiry and understanding
45
critical theory
Critique of society § Envisions new possibilities § Action oriented § Inspire change
46
feminist research
Similar to critical theory § Focuses specifically on gender domination/discrimination § Goal: facilitate change to end women’s unequal social positions
47
Participatory action research
Production of knowledge can influence power · Also focuses on action, empowerment, and raising awareness
48
quantitative methodology types
experimental quasi-experimental correlational descriptive
49
experimental
Randomized Controlled Trials (RCT) · “True Experiment” · Level 1 (pg 23 Fig 2.1) · Gold standard · Test the effects of an intervention AND random groups assigned
50
correlational
§ Level III § Examine relationship between variables § Non-experimental study § Correlations can be detected through statistical analyses § Does not prove causation
51
descriptive
Level III § Observe, describe, document situation
52
Quasi-experimental research design characteristics
- Has an intervention - Lacks randomization - less control than true experimental designs - samples not randomly assigned
53
types of quasi-experimental
nonequivalent control groups | time series design
54
nonequivalent control groups
same as pretest-posttest but lacks randomization (weaker)
55
time series design
looking at extended periods of time
56
randomized control trials characteristics
intervention control randomization
57
reasoning
logical reasoning process
58
2 types of reasoning
deductive | inductive
59
deductive reasoning
quantitive, looks at facts rules and definitions
60
inductive reasoning
qualitative, uses patterns and behaviors to arrive at a conclusion
61
reliability
Consistency of measurement technique/associated with the methods § Correlation coefficient (r)= how the degree of realibility is expressed § Reliability coefficients normally range from 0-1.0 (>0.8 is desired) § Cronbach’s alpha coefficient=most common measure of realibility
62
research hypothesis
predict the existence of a relationship o Predicted answers to research questions o State the expected relationship between the IV and DV o Offer direction o Suggest explanations o Promotes critical thinking directional, nondirectional, null
63
Research question – identify independent and dependent variables
Questions researcher wants to answer o Independent (cause) o Dependent/Outcome variable (effect)
64
secondary sources
Summarizes or quotes from primary source o Only use source if cannot locate primary
65
Social desirability response set bias
A tendency to misrepresent attitudes or traits by giving answers that are consistent with prevailing social views
66
Steps of Descriptive Qualitative Research
bracketing intuiting analyzing describing
67
bracketing
Identifying preconceived ideas (beliefs & opinions) | May use reflexive journal to bracket
68
intuiting
Remain open to new meanings
69
analyzing
Make sense of new meanings
70
describing
Come to full understanding and define the phenomenon
71
temporal ambiguity
2 variables and you’re not sure which one is the cause and which on is the effect
72
transferability
The extent to which qualitative findings have applicability in other settings or groups
73
Truncation symbol
Use of a asterisk *- this expands a search term to include all forms of the root
