Document Summary
Personality assessment: measurement of the individual characteristics of a person. Reliability- extent to which test scores are consistent and reproducible with repeated measures. Temporary consistency reliability- checked by having respondents take the test a 2nd time to see if their scores are similar. Internal consistency reliability- checked to see if different items of the test give similar results. Parallel-forms reliability- 2 versions of a test that are comparable and checked to see that the scores on the parallel forms of the test were similar. Split-half reliability- a test is split in half and see if test-takers" scores on one half correlated with scores on the other half. Interrater reliability- (to make sure measures are reliable across multiple raters) might have 2 separate judges rate the personality or behaviour of a 3rd person. Researchers will often calculate average correlation among the scores of all raters or the percentage agreement among raters.
