Computerized testing augments pencil-and-paper tasks in measuring HIV-associated mild cognitive impairment(*).

摘要: Background Existing tools for rapid cognitive assessment in HIV-positive individuals with mild deficits lack sensitivity or do not meet psychometric requirements tracking changes ability over time. Methods Seventy-five nondemented patients were evaluated the Montreal Cognitive Assessment (MoCA), a brief battery of standardized neuropsychological tests, and computerized tasks evaluating frontal-executive function processing speed. Rasch analyses applied to MoCA data set subsequently full from all tests. Results The was found adequately measure as single, global construct this cohort, although it showed poorer precision measuring higher ability. Combining additional tests resulted better properties that also targeted range abilities cohort. Conclusion This application modern test development techniques shows path towards quick, quantitative, approach promise both initial detection longitudinal follow-up impairment HIV infection.
