Structured Personality Test Flashcards
Minnesota Multiphasic Personality Index
What it is it?
true / false questions items about personality characteristics validity scales self report 2 alternative forms
MMPI-II
3 Validity scales
K scale - checks for giving socially desirable
L scale - lie scale
F scale - infrequently endorsed items. Checks people who take an unusual approach to testing.
high scores = biased results (in theory)
MMPI-2
Advantages
recent standardisation
extensive use
high researcher interest
MMPI-2
Problems
Item overlap amoung scales
imbalance t/f keying
high intercorrelation among scales
lack of generalisability across PV demographics
MMPI-2 How constructured
Criterion group strategy.
group with known characteristics vs. control group
Items that distinguished criterion group included in scale
cross-validated on an independent sample of criterion and control.
Attempted to discern an items meaning empirically
MMPI-2 assumptions used in construction
people diagnosed correctly
Assumes people are honest
4 test construction methods and examples
Logical Content Strategy - Woodworth Personal Data Sheet
Criterion Group - MMPI-2
Factor Analytic Strategy - 16 PF by Cattell
Theory Method - Edwards personal preference schedule; Jackson Personality Inventory,
Combination strategy - NEO personality inventory
Test Construction - Logical Content Strategy
Assumes
Items can be interpreted @ face value
subject takes a normal approach, comply, read instructions and are honest
Logical Content Strategy for test construction
uses reason and deductive logic to develop items.
Logical Content Strategy for test construction example
Woodworth Personal Data Sheet - First personality inventory WWI
Identify recruits likely to break down in combat
identified people at risk who needed further screening`
Woodworth Personal Data Sheet - Items
forced choice items
items lists of known symptoms of emotional disorders
single score
items endorsed by 25% or more of a normal sample excluded from the test.
Test construction - theoritical strategy example
Edwards personal preference schedule
personality research form
jackson personality inventory
Theoritical Strategy - Edwards Personal Preference Schedule (EPPS)
Items selected to measure variables specified by a theory of personality
EPPS is based on Murray (1938) theory of needs
15 needs such as
accomplish, conform, exhibition,
constructed items with content validity for each need.
EPPS - Response style bias solution
Items rated on social desirabilty.
Items with similair social desirability paired.
EPPS - Scoring
Ipsative scores: results are compared with the person taking the test expressed in relative strength of need
Forced choice between options = in social desirability but can still be fake
15 scales low correlations
