Value of Global Self-Ratings in Differential Diagnostics

摘要

Reliability validity and faking tendencies of a 10 dimensional personality inventory were compared with the corresponding global self ratings in a situation of job application. Global self ratings do not appear to be faked more than the personality test scales. Although there are distinct differences in reliability between self rating and personality scales, the latter attain only negligibly higher validities. Reasons for these results (unexpected from assumptions of classical testing theory) are discussed. In relation to self ratings in performance, there are indications of a capability of self assessment.
