Document Summary
Personality assessment is the measurement of the individual characteristics of a person. Though there are many types of methods that researchers use to study personality, the most commonly used are personality tests. The biggest difference between a personality test you might find on the. Internet and what you find in journals or purchase from recognized publisher is that legitimate personality tests have reliability, validity, and generalizability, backed by research evidence that is available for public scrutiny. Test reliability: generalizability across time, items, and raters. We cannot know the correct time with an unreliable watch. A measure must first be consistent in order to be a valid representation of an underlying theoretical construct. Reliability is an estimate of how consistent a test is: a good test gives consistent results over time, items, or raters. Reliability describes the extent to which test scores are consistent and reproducible with repeated measurements.
