Treats to Validity
Name a common threat to Construct Validity
•Operational definitions
•Comprehensive measurements
•Subgroup differences
•Time frame
•Multiple treatment interactions
•Experimental bias
This type of design helps to provide structure for evaluating the cause-and-effect relationship between a set of independent and dependent variables.
Experimental Design
What is the independent variable in a Time Series Design?
Time
For Casey's article (Article #1), what Quantitative study design was used to determine the PLISSIT models' effect on sexual dysfunction for women with SCI?
Randomized clinical trial with two parallel groups
Occurs when a participant's behavior changes as a result of being observed, rather than as a result of an intervention
Hawthorne Effect
This is the basic structure of randomized controlled trials. They are often used to compare two or more independent groups to see if there are significant differences between group outcomes from before to after intervention.
Pretest-posttest Control Group Design
What are the three types of Time series Designs?
One-group pretest-posttest, repeated measures, and interrupted time series design
For Christina’s article (Article #3) What type of study design and method to collect data was used in her article about sexual reeducation?
Qualitative Semi-Structured Interviews
What type of internal validity threat refers to the pressures that can occur in research situations that may lead to differences between groups? These threats have also been called performance bias.
Social Treat
In this research design, the subjects are used as their own control during conditions.
Repeated measures design
Which design has multiple pretests and posttests?
Interrupted Time Series Design
What does PFMT stand for?
Pelvic Floor Muscle Therapy
Random assignment and homogeneous samples are examples of strategies to control for what?
Subject variability
In this group design, no pretest is administered to either group.
Posttest-only Group Design
True or False, the Nonequivalent posttest-only control group design is used for explanatory purposes.
False, used for exploratory
For Christina’s article (article #3) What three themes emerged from the results of the qualitative semi-structured interviews?
Capability, Opportunity and Motivation
In addition to controlling for confounding variables in a design, it is important to maximize WHAT to the research protocol for the most reliable results.
Compliance and/or Adherence
Incorporates two or more independent variables, with independent groups of subjects that are randomly assigned to various combinations or levels of the variables.
Factorial Design
Which design measures the dependent variable multiple times?
Repeated Measures Design
What is OT's role in Quantitative Research?
Ability to design and measure occupational performance in relation to a disease or disability for greater translation of results to the public.
