Title : Validation study of the cogniscan computerized test for memory and processing speed in a Brazilian sample
Abstract:
Objective: To evaluate the psychometric properties of the Cogniscan screening test, a self-administered software for assessing episodic and working memory, focusing on validating its accuracy in a Brazilian clinical sample. Participants.
Methods: This study involves 300 volunteers aged 18 years or older with at least four years of schooling. Participants will answer a sociodemographic and quality of life questionnaire, in addition to taking the G-38 intelligence test, the Recognition Memory Test (TEM-R-2), attention tests (AOL) and the computerized Cogniscan, which assesses episodic and working memory and processing speed. The results of the Cogniscan are expected to be equivalent to those of the TEM-R-2, showing impressive reliability and construct validity indices.
Results: Preliminary data from 54 participants show a mean age of 36.7 years (SD = 13.4), with a predominance of women (66.7%, n = 33) over men (33.3%, n = 18). Regarding education, 42.6% of the participants had higher education (n = 23), and 37% (n = 20) had postgraduate degrees. The results of the cognitive tests were expressed as means and standard deviations, demonstrating the variation in the use of Cogniscan as a screening tool.
Conclusions: Initial results suggest that the Cogniscan test has potential as an effective tool for cognitive monitoring and early detection of declines. Validation of this software may significantly contribute to preventive and therapeutic interventions, promoting a better quality of life in the different stages of aging.
