Validation d'un test de barrage informatisé sur tablette évaluant les fonctions exécutives auprès d'une population gériatrique

Abstract : In the context of early detection of cognitive impairment associated with dementia, an area of research focus concerns development and validation of computerized tests. We have developed a tablet-based cancellation test (e-CT), based on an existing paper-and-pencil cancellation test (K-T test). We studied the variables influencing performance on the e-CT and its psychometric properties. Among healthy older adults, only age was found to be an influencing variable. The performance on the e-CT was not influenced by experience with a computer-based device. However, for patients suffering from cognitive impairment, those using a computer-based device daily outperformed those who were not daily users. Further analyses showed that daily users conserved better cognitive capacities than non-daily users. The e-CT showed significant correlations with several measures of executive functions (convergent validity), but there was no relationship between the e-CT and the episodic memory test (divergent validity). It showed good test-retest reliability. The e-CT had good diagnostic accuracy in differentiating between healthy elderly subjects and patients with cognitive impairment. In conclusion, the e-CT test shows satisfying psychometric properties and is a promising tool for neuropsychological assessment in older adults
