Abstract
This study examined the test validity of the respondent validity scales of the Ruff neurobehavioral inventory (RNBI). In a private practice sample of motor vehicle accident pain patients (n = 54) without neurologic injury, the scores obtained for these scales were compared with and correlated with equivalent ones on the Millon clinical multi-axial inventory III (MCMI III) and the Detailed assessment of post-traumatic stress (DAPS). Results revealed that there was a consistent pattern of convergence and divergence in response styles across the three instruments. In terms of the RNBI interscale correlations, in particular, the results suggested that premorbid positive impression management and postmorbid negative impression management are related in this type of sample. These findings add to the concurrent validity of the RNBI, suggesting that the instrument provides relevant incremental information about the type of population studied. Limitations of the study and ideas for future research were discussed.
