assessment and methods Flashcards
self-report questionnaires
questionnaire that gets people to report on their own personalities by rating themselves on a list of adjectives or statements
problem with self-report questionnaires
may be biased through socially desirable responding
likert scale
a range of numbers that cirrespond with how much a person agrees or disagrees with an item
reverse-score items
items scored in the opposite direction of responses, whch prevents acquiescence response set (tendency to agree with/ go along with the statements/items)
correlation
relationship between 2 things/variables
positive correlation
as one variable increases, so does the other
negative correlation
as one variable increases, the other decreases
null correlation
no relationship
correlation range
-1 to +1
reliability
consistency of a personality scale
internal reliability
items on a scale/test measure the same thing
chronbach’s alpha
average of the correkations between all items on a scale/test
should be at least 0.70
test-retest reliability
consistency of a person’s scores when they re-take a scale/test
intercoder reliability
consistency of coding by researchers measuring the same behaviours or written responses
validity
accuracy of a personality scale
face validity
items on a scale appear to be accurate
convergent validity
scale correlates with similar scales
predictive validity
when a scale can predict a related outcome or behaviour
discriminant validity
scale doesnt correlate with dissimilar scales
Marlowe-Crowne scale
measures a person’s need for social approval/social desirability
how much you want to be socially desirable, not actually how socially despirable you really are
informant reports
person cannot fill out a self-rport questionnaire so someone does it on their behalf
clinical interviews
to diagnose a personality disorder
projective tests examples
rorshach test
TAT (thematic apperception test)
repressive coping
people who score high on Marlowe-Crowne test often score low on self-reported anxiety, however, they show higher degrees of anxiety through physiological measures such as high blood pressure and high heart rate
does correlation show cause and effect
NOPE
confounding variables, unsure which one causes which without experiements
