Highlights
- •We confirmed Criterion validity for MTL-BR.
- •We found significant differences between patients with aphasia and controls on MTL-BR.
- •Aphasia group differentiated from other clinical groups in almost all MTL-BR tasks.
Abstract
Background
The Montreal–Toulouse Language Assessment Battery — Brazilian version (MTL-BR) provides
a general description of language processing and related components in adults with
brain injury.
Objective
The present study aimed at verifying the criterion-related validity of the Montreal–Toulouse
Language Assessment Battery — Brazilian version (MTL-BR) by assessing its ability
to discriminate between individuals with unilateral brain damage with and without
aphasia.
Methods
The investigation was carried out in a Brazilian community-based sample of 104 adults,
divided into four groups: 26 participants with left hemisphere damage (LHD) with aphasia,
25 participants with right hemisphere damage (RHD), 28 with LHD non-aphasic, and 25
healthy adults.
Results
There were significant differences between patients with aphasia and the other groups
on most total and subtotal scores on MTL-BR tasks.
Conclusions
The results showed strong criterion-related validity evidence for the MTL-BR Battery,
and provided important information regarding hemispheric specialization and interhemispheric
cooperation. Future research is required to search for additional evidence of sensitivity,
specificity and validity of the MTL-BR in samples with different types of aphasia
and degrees of language impairment.
