Latent structure of the Test of Everyday Attention: convergent evidence from patients with traumatic brain injury.
OBJECTIVE
The present study aimed to examine the nature of attention distinctions among sub-tests of the Test of Everyday Attention (TEA) underlying the performance of patients with traumatic brain injury (TBI).


METHODS
Confirmatory factor analysis was performed among a group of 92 patients with TBI experiencing chronic post-concussive symptoms. Comparisons were made of the fit of the previously identified models based on exploratory factor analysis, comprising three-to-four factors.


RESULTS
The results indicated that the 3-factor model with a visual selection component, a sustained attention component and a switching component provided an appropriate account of attentional performance than the other two 4-factor models.


CONCLUSIONS
These findings are consistent with those of healthy sample. This study, therefore, provides convergent evidence on the latent structure of the TEA. It is consistent and stable across healthy and clinical populations.
