Evidence of validity based on the relation to other variables and inter-rater reliability of the Cognitive Screening (TRIACOG) for adults with cerebrovascular diseases.

This study presents evidence of validity and reliability of the results obtained with the Cognitive Screening (TRIACOG) to evaluate post-stroke adults. The TRIACOG assesses orientation memory, language, arithmetic, praxis, information processing speed, and executive functions. A total of 126 post-stroke adults (M = 63.50; SD = 13.28 years old) and 126 neurologically healthy adults (M = 61.97; SD = 11.48 years old) participated in the study. Performance on the TRIACOG was positively correlated with scores on the Montreal Cognitive Assessment-Basic (MoCA-B), schooling, and reading and writing habits, and negatively correlated with the NIHSS and Rankin scales. Post-stroke adults scored lower and took longer to complete the instrument than neurologically healthy adults. Inter-rater agreement was achieved in scoring the TRIACOG. The TRIACOG presents evidence of validity based on its relationships to other variables (criterion and convergent) and on response processes, in addition to presenting reliability evidence established by inter-rater agreement. We expect that the TRIACOG will be employed by health workers in hospital settings, health units, and medical offices.
