K. Moser et al., VALIDITY OF SELF-ASSESSMENT OF WORK PERFO RMANCE - A STUDY IN INDUSTRIAL-RESEARCH AND DEVELOPMENT, Zeitschrift fur experimentelle und angewandte Psychologie, 41(3), 1994, pp. 473-499
Based on a literature review, the psychometric criteria (reliability,
validity, rating tendencies) as well as the (assumed) moderators of th
e validity of self-assessment are presented. A closer examination show
s that most existing studies on the validity of self-assessment did no
t refer to work performance. Therefore, the quality of self-assessed w
ork performance was investigated in a sample of scientists and enginee
rs in industrial R & D. Especially, metaanalytic results were used in
order to improve the conditions for higher validity of self-assessment
(anonymity, social comparison instruction, information that self-asse
ssment will be validated). In the present study, no leniency effect wa
s found in self-assessment compared to supervisory's assessment. In ag
reement with earlier results, self-assessments have lower standard dev
iations and less halo than supervisory's assessments. The correlation
(validity) between self- and supervisory's assessment is r = .42 (n =
144). Further moderator analysis confirmed the robustness of this resu
lt. Finally, explanations for the limited validity of self-assessment
are discussed.
