Faking and demand characteristics can represent significant threats to
the validity of role-play tests of social competence. The present stu
dy examined whether faking could be detected via the global judgments
of experienced and inexperienced assessors. 26 undergraduates low in a
ssertiveness were induced to fake their performances on the Idiographi
c Role-play Test via instructions and information. Experienced judges
successfully differentiated faking subjects from highly assertive subj
ects (n = 27) who had been provided with information and nonfaking ins
tructions (98% accuracy). Inexperienced assessors correctly classified
79% of the subjects. Within the discussed limitations of this study,
it appears that it is possible to detect faking on role-play tests of
assertiveness.
