This study assessed trait validity of the Reynolds Intellectual Assessment Scales' (RIAS) Verbal Index (VIX) and Nonverbal Index (NIX) scores in a group of college students. Using both observation of patterns and latent variable modeling of a multitrait-multimethod correlation/covariance matrix, the results indicate that the RIAS VIX scores behaved in a manner predicted from the theory behind their construction; namely, they related strongly to other measures of crystallized intelligence ("Gc") and, together, they formed a salient "Gc" factor. The NIX scores, however, did not behave as predicted--showing as strong, or stronger, associations with measures of "Gc" than measures of fluid intelligence. Although more studies of this type are needed across different samples before making broad generalizations, the results from the present study support the use and interpretation of the RIAS VIX score, but not the NIX score.
