The factorial validity of the attentional-style subscales of the Test of Attentional and Interpersonal Style (TAIS) have recently been questioned, although the evidence is only indirect. This study aimed to examine, directly, the factorial validity of these scales and to cross-validate the results. Two samples of 210 first-year psychology students responded to the 52 items comprising the attention-related subscales of the TAIS. A multidimensional confirmatory factor analysis (MCFA) was conducted on the interitem covariance matrix to test the measurement model underlying the six subscales. The MCFA results failed to support the model. Furthermore, internal consistency coefficients and item-total coefficients also supported the view that many of the subscales have insufficient factorial validity. Of the 52 items, 44% correlated better with at least one subscale other than their own, which indicates poor discriminant validity. Analysis of item content reveals some explanation for the poor discriminant validity. All results were cross-validated with the second sample.
