Assessment And Dx Flashcards
(331 cards)
MMPI2 validity scale k
Measures guardedness and defensiveness
Serves as moderator variable— adjusts for defensiveness
MMPI scale L
Naive attempt to present favorably
MMPI F scale
Measures infrequently endorses items- used to assess overall distress and pathology, attempts to fake bad or random responding
MMPI VRIN and TRIN
Response inconsistency or random responding
Standard error of estimate
Direct rel with the SD of criterion
Indirect rel w validity (when validity is high, there should be little error in prediction and vice versa)
Halo effect
Being influenced by only 1 attribute when evaluating so
Can be controlled by training, utilizing forced choice, and objective methods like the BARS
Range of standard error of measurement
Index of Amt of error expected in obtained score for individuals d/t unreliability of the test
0 to SDx (test)
Range of validity coefficient
-1 to 1
Range of reliability coefficient
0 to 1
Range of standard error of estimate
0 to SDy (criterion)
selection ratio
of openings over # of applicants
base rate
rate of successful hiring without test
criterion validity
correlation between scores on the validity test and scores on the outcome measure of performance production
what effects incremental validity
base rate, selection ratio, criterion validity
concordance rates for twins with bipolar
75%
adverse impact
percentage of minorities hired is less than 4/5 % of non-minorities. Can multiply hiring rate for non minorities by .8
Reliability
Consistency.
Correlating the test with itself.
Do items measure what they’re supposed to measure?
Ex. .84 means 84% of variability in scores is due to score differences among examinees and 16% is due to measurement error
Factors that affect reliability
- Test length- longer is better for rel
- Range of scores- unrestricted is best for rel
- Guessing - as probability of guessing right increases, rel decreases
Content validity
Extent to which a measure represents all facets of a given construct
Ex depression scale may lack content validity if it only measures affect
Construct validity
The degree to which a test measures what it claims to be measuring
Do all items measure the same construct?
Criterion validity
Extent to which a measure is related to an outcome
Concurrent: compare measure in question and an outcome measured at the same time
Predictive: compares the measure in question with an outcome predicted at a later time
item response theory
It is a theory of testing based on the relationship between individuals’ performances on a test item and the test takers’ levels of performance on an overall measure of the ability that item was designed to measure.
criterion keying approach to constructing a personality inventory (i.e., MMPI)
discriminate among various criterion groups
primary mental abilities test
multifaceted test of intelligence
