Lecture 4.1 Flashcards
(21 cards)
1
Q
defintion validity
A
- does the test measure all and nothing else
2
Q
face validity
A
- surface impression of examinee
3
Q
content validity
A
- does the test cover the whole contruct
4
Q
method of content validity
A
- panel of experts
- proportion of items that are deemed relevant
5
Q
criterion validity
A
- compared to external standard
6
Q
concurrent validity
A
- part of critirion validity
- e.g. a diagnosis
7
Q
predicitve validity
A
- prediction of future behavior
8
Q
requirements for critirion validity
A
- reliable
- free of contamination (overlap)
9
Q
decision theory
A
- hits = correct prediction
- false positive = flase alarm
- false negative = incorrectly classified
10
Q
sensitivity
A
- how well the test picks up real things
11
Q
specificty
A
- correct negative classifications
12
Q
convergent validity
A
- correlation with similar instrument
- part of construct validity
13
Q
multimethod
A
- different instruments to test
- assesses convergent validity
14
Q
multitrait
A
- correlation with unrelated tests
15
Q
multitrait-multimethod matrix
A
- table to asses correlation of convergent and discriminate validity
16
Q
factor analysis
A
- how much independent constructs does the test include
17
Q
explanatory factor analysis
A
- explore underlying structure
18
Q
confirmatory factor analysis
A
- theory tries to be confirmed
19
Q
threats to validity
A
- no relation with construct
- construct overrepresentation (more constructs than intended)
20
Q
validity shrinkage
A
- validity changing exmtremely in another sample
21
Q
types of criterion validity
A
- concurrent validity
- predictive validity
(- postdictive validity)
