Chp 2 - Personality Assessment, Measurement and Research Flashcards
Reliability
the consistency of scores that are expected to be the same
Internal consistency reliability
Degree of consistency measured by seeing whether subparts or equivalent parts of a test yield the same results (e.g. split-half)
Repeated Measurements
- Test-retest, consistent across time
Temporal stability
when you retest, it is the same over time, consistent
Construct Validity
Measures what it claims to measure
What 3 validity (in slide) are included in construct validity?
- Predictive validity
- Convergent validity
- Discriminant validity
Predictive (Criterion) Validity
Do the test results predict behaviours related to the construct?
Eg. Measure conscientiousness:
Related to honesty, does your measure of conscientiousness predict how truthful someone is?
Convergent validity
Does the test include testing for related behaviours
e.g. if theory suggest extraversion included being talkative, does test of extraversion include being talkative?
Try to capture a range of behaviours
Discriminant Validity
The test does NOT measure unrelated characteristics
e.g someone high in introversion shouldn’t necessarily score high in unrelated characteristics, such as fearfulness
Face validity
does the test make sense?
What are the three major sources of bias in personality assessment
gender, ethnic, response sets
Gender Bias
Expectations based on sex can influence test construction and interpretation
e.g. certain traits may seem more feminine…
Response Set
Tendency to respond based on factors other than what is being measured
3 types of common response sets
- acquiescence
- extreme responding
- social desirability
Response set (acquiescence)
tendency to agree with statements
(Use reverse score to combat)
