OBJECTIVE: The present study examined whether the everyday problems test (EPT), a performance-based measure of everyday problem-solving, can be considered a useful test in assessing functional independence in patients with traumatic brain injury (TBI). The relationship between EPT, cognitive abilities (i.e., selective attention, set switching, and working memory) and self-rated measures of everyday functioning and disability in these patients was also assessed.
METHOD: In this case-control study 25 postcomatose outpatients with TBI (age M = 35.9, SD = 14.21) from a neurorehabilitation unit and 25 matched controls were enrolled. Participants were administered the EPT along with neuropsychological tests of selective attention, set switching and working memory, and self-rated measures of everyday functioning and disability.
RESULTS: Patients with TBI were less accurate and slower than controls in the EPT; the two groups were accurately classified based on EPT completion time (likelihood ratio test χ2 = 28.67, R2 = 0.72, p < .001). In the patient group education and selective attention explained a large portion of variance in EPT accuracy (R2 = 0.53, p = .001), while only selective attention explained a significant portion of variance in EPT time (R2 = 0.24, p < .01). Self-rated measures of everyday functioning and disability did not significantly contribute to EPT performance variance.
CONCLUSION: Including performance-based measures as the EPT in a multifactorial approach to assessment can be useful for unraveling cognitive factors contributing to TBI's impact on everyday functioning. Since attentional processes seem to play a significant role in determining EPT performance, rehabilitation of functional independence should target this ability first.
