Exam 2 Flashcards
what are the research designs that use an intervention? (3)
- experimental
- randomized controlled trials
- quasi-experimental design studies
what’s an example of a study that does not have an intervention but compares two groups of people?
observational study
these are variables that can influence the outcome that weaken the link between the independent and dependent variable
confounding variables
methods to control confounding variables from influencing outcomes of studies:
- Randomization
- crossover
- homogeneity
- matching
- statistical control
“really controlling how mary studies”
what’s the main way to get rid of bias?
“blinding”
the more groups blinded in a study, the less _____ present in a study.
BIAS
re: data collection, what is cross sectional design
one specific time
re: data collection, what is longitudinal design
across extended period of time or multiple times
study looking backwards
retrospective study
is a retrospective study considered a primary or secondary study?
secondary
data has already been collected by someone other than researcher
what is a study that’s looking forward called?
prospective cohort study
between cause and effect, which is the independent variable and which is the outcome? relate cause and effect to PICO terms
cause: independent variable (things that’s changed) / pico: I
effect: outcome / pico: O
3 traits to establish causal relationships
- temporal
- relationship
- confounders
“threesomes rarely count”
re: causal relationships, this trait requires a cause to precede an effect
temporal
re: causal relationships, this trait requires an association to be shown between the cause + effect
relationship
re: causal relationships, this trait requires it to be proven that the effect cannot be caused by a 3rd variable
confounders / confounding variable
a randomized controlled trial (RCT) always has what components? (3)
- intervention
- control
- participants chosen randomly
re: RCTs, which design measures the outcome indicator before?
pre test (baseline data)
re: RCTs, which design measures the outcome indicator after the intervention?
post test data
how is randomization usually achieved?
computer programs
what is this design: giving more than one treatment, but separate them out and use randomization to determine ordering
crossover design

taxonomic analysis
re: ethnographic (qualitative) analysis, this is analyzing data for similarities and differences among cultural terms in a domain.
componential analysis
“componential = compare”
re: ethnographic (qualitative) analysis, this is when cultural themes are uncovered and connected to domains to help provide a holistic view.
theme analysis

the goal for these types of analyses are to describe the essential nature of an experience through the identification of specific themes
phenomenological analysis
what are the 2 main methods of analyzing data for Grounded Theory? (People assiciated with)
Glaser and Strauss
**the grounded theory analysis slide was a bitch….
too lazy at this point. go back to ch. 16 slide 6 if you’re feeling froggy.

D
others are quantitative
What is narrative information in a qualitative study broken down into first? A) Constructs B) Theory C) Codes D) Themes
C
then themes, then constructs + theories
Which style of qualitative analysis uses domain analysis? A) Qualitative Content Analysis B) Ethnography C) Phenomenology D) Grounded Theory
B
Which phenomenologist analyzes artistic works in their analytical methods? A) van Manen B) Colaizzi C) Heidegger D) Giorgi
A
Colaizzi: go back to participants to verify findings
Heidegger: something about a circle lol
What method is present in all areas of grounded theory analysis? A) selective coding B) conceptual description C) paradigm development D) constant comparison
D
re: qualitative studies, this is the measure of truth in the data and how it is interpreted
credibility
re: qualitative studies, this is the ability of the study findings to be repeated in similar circumstances
dependability
if not dependable, it’s not credible
re: qualitative studies, this is making sure the data reflects the participants view or voice rather than the researcher’s
confirmability
re: qualitative studies, this is the ability for the results to be applied or assumed for other settings
transferability
re: qualitative studies, this is the ability for readers to get a true sense of a participant’s lived experience; reflects the ability of the researchers to faithfully show a range of different realities.
authenticity
re: qualitative studies, this is the investment of sufficient time collecting data to have an in-depth understanding of the culture, language, ore views of the people or group under study
prolonged engagement
builds rapport with patient to get rich info
re: qualitative studies, this refers to researcher’s focus on the characteristics or aspects of a situation that are relevant to the phenomena being studied
persistent observation
re: qualitative studies, this is the ability of a researcher to be mindful of their own bias on collection, analysis, and interpretation of data
reflexivity
clearest strategy to address researcher bias - journaling is a way to practice this
re: qualitative studies, data triangulation uses which 3 factors?
time, space + person
re: qualitative studies, this is creating a collection of raw data, methodological notes, topic guides, and drafts created by the researcher. The goal is to allow another investigator to assess the data and draw conclusions.
aduit trail
What component is required in qualitative research to claim a study is credible? A) Confirmability B) Authentiticy C) Transferability D) Dependability
D
What is a strategy used in qualitative research to reduce bias? A) Prolonged engagement B) Reflexive journaling C) Persistent observation D) Audit trail
B
What process in qualitative research involves checking that the themes are congruent with the participant’s beliefs? A) Member check B) Triangulation C) Reflexivity D) Persistent Observation
A
What strategy in a qualitative study involves getting multiple researchers for data collection, coding, and analysis? A) Inquiry audit B) Investigator triangulation C) Negative case analysis D) Peer debriefing
B
Which technique helps establish researcher credibility in qualitative research?
A) Investigator Triangulation with at least three researchers
B) Audit Trail conducted before two inquiry audits
C) Peer debriefing with at least five peers
D) Including information about the researcher in the study
D
this Integrates research from multiple sources
systematic review
what is the most known place systematic reviews can be found?
Cochrane Collaboration
Systematic review with meta-analysis is found with which type of study?
quantitative
Systematic review with meta-synthesis is found with which type of study?
qualitative
Synthesis = Subjective
re: meta-analysis, this is used to determine the relationship between variables across multiple studies
effect size
the question for a meta-analysis should be ____ or ______
narrow or focused
what is a factor assessed to determine if a meta-analysis is appropriate
statistical heterogeneity
(are the results conflicting between different studies on the same research question?)
if they have conflicting results, it’s NOT appropriate to use a meta-analysis
this collects data from multiple studies and analyzes themes
metasynthesis - multiple qualitative studies
What component is used in types of systematic reviews to measure the impact of the independent variable? A) Sample B) Research Design C) Effect Size D) Outcome
C
When would it not be appropriate to use a meta-analysis?
A) multiple studies have a similar research question
B) good quality studies with conflicting results
C) mostly primary research studies related to the phenomenon
D) Cohen’s d can be easily calculated
B
What is a risk that can occur in a meta-analysis if the study excludes articles are that are not peer-reviewed? A) Intrinsic bias B) Reduced validity C) Publication bias D) Reduced reliability
C
What technique is used to display the effect sizes of multiple studies to assess if it is appropriate to do a meta-analysis? A) Forest plot B) Cohen’s d C) Odd’s Ratio D) Pearson’s r
A
What is different about the research design for a metasynthesis versus a meta-analysis?
A) focus on primary research studies
B) researchers same as those of studies included
C) calculate effect size for data analysis
D) begin with a focused research question
B
