CALDAS, Vescia Vieira de Alencar; ZUNZUNEGUI, Maria Victoria; FREIRE, Aline do Nascimento Falcão  and  GUERRA, Ricardo Oliveira. Translation, cultural adaptation and psychometric evaluation of the Leganés cognitive test in a low educated elderly Brazilian population. Arq. Neuro-Psiquiatr. [online]. 2012, vol.70, n.1, pp.22-27. ISSN 0004-282X.

OBJECTIVE: To validate the Leganés cognitive test (LCT) for cognitive screening in low educated elderly Brazilians. METHODS: The study sample was composed of 59 elderly residents from the city of Santa Cruz, in Brazil, with low schooling levels. Reliability was analyzed with a two-day interval between assessments, and concurrent validity was assessed using the Mini Mental State Examination (MMSE). RESULTS: According to the LCT, the prevalence of dementia was 11.8%. The scale items showed a moderate to strong correlation between domains (p<0.01), and inter-rater reliability exhibited ICC=0.81, 95%CI=0.72-0.88. The factor analysis resulted in two factors: memory and orientation. Interscale agreement was considered poor (k=-0.02), supporting the hypothesis of an educational impact on final MMSE scores. CONCLUSION: The results suggest that LCT has acceptable levels of reliability for use in low-educated Brazilian elderly.
