International HIV Dementia Scale: Screening for HIV-Associated Neurocognitive Disorders in Occupational Settings

ABSTRACT

This study investigated whether the International HIV Dementia Scale (IHDS) can be used to screen for milder forms of HIV-associated neurocognitive disorder (HAND) in occupational health settings. It explored first; the effect of demographic variables on IHDS performance in a sample of HIV-negative employees and second; the extent to which the IHDS can differentiate between milder forms of HAND in HIV-infected employees. Data from 476 HIV-negativeand 90 HIV-positive individuals indicated that; although clinicians need to be sensitive to the effect of education and test-language proficiency; separate norms based on socio-demographic variables are not required in this context; and that the IHDS shows promise for identifying milder forms of HAND in this HIV-positive sample; with ?10 the recommended cut-off for further referral. In conclusion; there is support for the IHDS to screen for HAND where this may impact on safety-critical tasks in the workplace
