In Brazil, no standardized instruments are available to asseADss
language in patients with aphasia. OBJECTIVE: The aim of the current study was to
search for reliability and validity evidence for the Montreal-Toulouse Language
Assessment Battery (MTL-BR). METHODS: The sample was composed of 537 adults, of
whom 463 were healthy individuals and 74 had neurological lesions (25
participants had right hemisphere brain damage, 21 had left hemisphere damage
(LHD) with aphasia and 28 had LHD without aphasia). Reliability was assessed by
internal consistency (Cronbach's alpha) and test-retest analyses. Test-retest
reliability was calculated using the Pearson correlation coefficient, and a
repeated measures analysis of variance, with years of education as a covariate.
Construct validity was verified by correlations between scores in MTL-BR subtest
and similar tasks from other language assessment instruments. RESULTS: Internal
consistency was satisfactory (Cronbach's alpha between 0.79 and 0.90), as were
correlations between test and retest scores (mean 0.52), and between the MTL-BR
and scores in similar instruments. CONCLUSIONS: The present results suggested
that the MTL-BR battery had adequate reliability and validity as a method for
diagnosing and monitoring aphasia.
