Lecture 3: Personality Assessment

Question 1

what are the four ways of assessing a personality trait

Answer 1

• self report (can be bias but views of the self from the self)
• observer data (unnatural, less bias, non intrinsic)
• test data (subjective, more variables)
• Life outcome data (can occur by chance, not biased, factual)

Question 2

what is validity

Answer 2

• the extent to which a test measured what it is supposed to measure
• we gain confidence in the construct

Question 3

what is reliability

Answer 3

• the degree to which the test represent “true” levels of this trait
• how accurate is it

Question 4

face validity

Answer 4

is there consensus that the test captures concept

Question 5

predictive validity

Answer 5

do scores on the test predict some important outcomes

Question 6

convergent validity

Answer 6

• do scores correlated with scores on a similar concepts
• to they converge with other established theories

Question 7

discriminant validity

Answer 7

• to what extent do scores correlated with concepts from which they should be distinct
• is the measure contaminated with other things

Question 8

construct validity

Answer 8

• how well does the test capture and represent the abstract concept
• basically a summary of all the different validities

Question 9

internal consistency reliability

Answer 9

• over items on a questionnaire/test: internal consistency

Question 10

over time reliability

Answer 10

• test retest correlation
• is it consistent over time?

Question 11

inter rater reliability

Answer 11

• raters look at the test and find consistency

Question 12

generalizability

Answer 12

• to what extent does our test remain valid in new context, different populations
