Abstract:
<p>BACKGROUND: Neurocognitive Impairment (NCI) is one of the most common complications of HIV-infection, and has serious medical and functional consequences. However, screening for it is not routine and NCI often goes undiagnosed. Screening for NCI in HIV disease faces numerous challenges, such as limited screening tests, the need for specialized equipment and apparatuses, and highly trained personnel to administer, score and interpret screening tests. To address these challenges, we developed a novel smartphone-based screening tool, , to detect HIV-related NCI that includes an easy-to-use graphical user interface with ten highly automated neuropsychological tests.AIMS: To examine : 1) acceptability among patients and different potential users; 2) test construct and criterion validity; and 3) sensitivity and specificity to detect NCI.METHODS: Fifty HIV+ individuals were administered a gold-standard neuropsychological test battery, designed to detect HIV-related NCI, and . HIV+ test participants and eight potential provider-users of were asked about its acceptability.RESULTS: There was a high level of acceptability of by patients and potential provider-users. Moderate to high correlations between individual tests and paper-and-pencil tests assessing the same cognitive domains were observed. also demonstrated high sensitivity to detect NCI.CONCLUSION: highly automated, easy-to-use smartphone-based screening test to detect NCI among HIV patients and usable by a range of healthcare personnel could help make routine screening for HIV-related NCI feasible. While demonstrated robust psychometric properties and acceptability, further testing with larger and less neurocognitively impaired samples is warranted.</p>
