Reliability: reliability consistency of scores expected to be the same, error variance variations of a measurement that are the result of irrelevant, chance fluctuations, highly reliable in giving consistent measurement. In constructing a personality test add relevant items until total score stable but don"t add so many items that the test becomes boring: coefficient of internal consistency reliability should generally be about 0. 80.

Content validity: content validity extent to which a test is measuring the domain it is supposed to measure.
