Document Summary
Personality assessment is the measurement of the individual characteristics of a person. Legitimate personality tests have reliability, validity, and generalizability. Test reliability: generalizability across time, items, and raters: reliability - an estimate of how consistent a test is, a prerequisite for validity, describes the extent to which test scores are consistent and reproducible with repeated measurements. A test should give consistent results across time, items, and raters: temporal consistency reliability: when an assessment gives consistent results over time, demonstrated through test-retest reliability (participants taking the test a second time) In test-retest, the second test has to be far enough removed in time so that there are no memory or practice effects, but not so far that the participants have changed in the interim. An alpha of 0. 7-0. 8 suggests a reliable test. Interrater reliability: when an assessment gives consistent results across raters (i. e. two separate judges rate the personality of a third person)
