What 3 components make up EBP?
1. Best current research
2. clinical expertise
3. abilities & perspectives of the client & his/her family
What does PICO stand for?
What is internal validity?
how well the study is testing or describing what it reports to be testing or describing
What is external validity?
generalizability of the results
What is the independent variable?
a condition that can change behavior (intervention)
What is the dependent variable?
the behavior that may change (outcomes)
What is an extraneous variable?
other factors that can alter the dependent variable, making it difficult to understand the relationship between the independent variable & the dependent variable
What is reliability?
how much can can depend on a measure
What is validity of measurement?
how well it measures what it purports to measure
What is content validity?
how well the test items measure the characteristics or behaviors of interest
What is criterion validity?
how well the measure correlates with an outside criterion that is known to be a good indicator of the characteristic or behavior of interest
What is construct validity?
how well the measure reflects a theoretical construct of the characteristic of interest
What is quantitative research?
data is obtained using numerical measures
What is qualitative research?
involves exploration of factors that may underlie behavior
What are the 3 types of quantitative research?
What is involved in experimental research?
the researcher manipulates one or more independent variables and observes the effect on the dependent variable
What is involved in descriptive research?
it is not possible for the researcher to manipulate the independent variable because it is a subject characteristic
What are the three types of group research designs?
A between-subject group design...
involves comparison of two or more groups of subjects
