| Abstract: | A prototypic experiment for validating computer-based test interpretations (CBTIs) was conducted. Undergraduates (N = 63) completed the Comprehensive Personality Profile Compatibility Questionnaire (CPPCQ; Craft, 1987). One treatment group rated real CBTIs for relative accuracy, and another group rated bogus CBTIs. A significant main effect for differences in ratings indicated that the real CPPCQ profiles were rated as 74.5% accurate whereas the bogus CBTIs were rated as 57.9% accurate. Several covariate effects were tested, but none were significant. |
