title: MacArthur Competence Assessment Tool for Treatment in Alzheimer disease: cross-cultural adaptation.
abstract: We adapted the MacArthur Competence Assessment Tool for Treatment (MacCAT-T) to Brazilian Portuguese, pilot testing it on mild and moderate patients with Alzheimer's disease (AD).
  The cross-cultural process required six steps. Sixty-six patients with AD were assessed for competence to consent to treatment, global cognition, working memory, awareness of disease, functionality, depressive symptoms and dementia severity.
  The items had semantic, idiomatic, conceptual and experiential equivalence. We found no difference between mild and moderate patients with AD on the MacCAT-T domains. The linear regressions showed that reasoning (p = 0.000) and functional status (p = 0.003) were related to understanding. Understanding (p = 0.000) was related to appreciation and reasoning. Awareness of disease (p = 0.001) was related to expressing a choice.
  The MacCAT-T adaptation was well-understood and the constructs of the original version were maintained. The results of the pilot study demonstrated an available Brazilian tool focused on decision-making capacity in AD.
