1

What 3 components make up EBP?

1. Best current research
2. clinical expertise
3. abilities & perspectives of the client & his/her family

2

What does PICO stand for?

1. Population
2. Intervention
3. Comparison
4. Outcomes

3

What is internal validity?

how well the study is testing or describing what it reports to be testing or describing

4

What is external validity?

generalizability of the results

5

What is the independent variable?

a condition that can change behavior (intervention)

6

What is the dependent variable?

the behavior that may change (outcomes)

7

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

8

What is reliability?

how much can can depend on a measure

9

What is validity of measurement?

how well it measures what it purports to measure

10

What is content validity?

how well the test items measure the characteristics or behaviors of interest

11

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

12

What is construct validity?

how well the measure reflects a theoretical construct of the characteristic of interest

13

What is quantitative research?

data is obtained using numerical measures

14

What is qualitative research?

involves exploration of factors that may underlie behavior

15

What are the 3 types of quantitative research?

1. Experimental
2. descriptive
3. mixed

16

What is involved in experimental research?

the researcher manipulates one or more independent variables and observes the effect on the dependent variable

17

What is involved in descriptive research?

it is not possible for the researcher to manipulate the independent variable because it is a subject characteristic

18

What are the three types of group research designs?

1. Between-subject
2. within-subject
3. both

19

A between-subject group design...

involves comparison of two or more groups of subjects

20

A within-subject group design...

the behavior of the same subjects is studied under different conditions
