Resumo: |
The use of virtual reality technology in clinical neuropsychology has received emphasis in the areas of assessment and rehabilitation in recent decades. Thereby, this doctoral thesis consisted of four studies with the objective of developing an ecological task in virtual reality for neuropsychological assessment in elderly (the ECO-VR), and provide evidence of its validity and reliability. Overall, the studies were characterized by cross-sectional, quasi-experimental, correlational, and between participants comparison design. At the development stage, the sample included 29 non-specialist judges, who analyzed the representativeness degree of the ECO-VR scene and three-dimensional stimuli, five expert judges have verified the apparent validity of the tasks, and six elderly who responded to the pilot studies. In other thesis studies, initial overall sample included 169 community dwelling elderly, recruited by convenience and snowball technique. In addition, 141 informants were included to respond questionnaires of cognitive complaints and functional capacity in relation to the elderly. After considering the exclusion criteria, final overall sample consisted of 149 elderly, 38 identified with mild cognitive decline, according to international criteria. In addition to the ECO-VR, the instruments used were a socio-demographic and clinical questionnaire, the CAGE questionnaire, the Mini Mental State Examination, the Geriatric Depression Scale-short form, a battery of neuropsychological tests, questionnaires of cognitive complaints and functional capacity. Data distribution was investigated by Kolmogorov-Smirnov, and associations between the scores of ECO-RV and other variables were investigated by Pearson correlation and stepwise multiple linear regression analysis. In the reliability tests, we used the Cronbach's coefficient alpha and the halves method (half-split), by adjusting the value according to the Spearman-Brown formula. Comparisons between groups were performed using chi-square test, Student's t test for independent samples, Mann-Whitney test and univariate analysis, and the effect magnitude was assessed by the Cohen’s d. A discriminant analysis was also carried out with enter method, and variance-covariance homogeneity was investigated with the Shapiro-Wilk test and Box’s M. Results were considered significant when p ≤ 0.05 and the SPSS 22 version for Windows was used for data analysis. According to the results, the ECO-VR has shown evidence for apparent, criterion, construct, and ecological validity, as well as adequate reliability indices. Correlations between ECO-TV scores and demographic data, neuropsychological performance and functional capacity were found. The inclusion of technological tools in the clinical neuropsychology field seeks to enhance the evaluation methods, particulary in the diagnosis of cognitive disorders associated with aging process. |
