The inclusion of HIV under the Americans with Disabilities Act has prompted many persons with HIV-1 infection to apply for disability, which raises the concern that a subset of these individuals might feign cognitive deficits to obtain benefits. This brief report provides base rate data on one SVT, the Hiscock Digit Memory Test (HDMT), in a sample of 82 non-compensation-seeking, neuropsychologically impaired participants who met diagnostic criteria for an HIV-associated neurocognitive disorder. Approximately 98% of individuals with HIV-associated neurocognitive disorders performed above an established HDMT cutoff for suboptimal effort (i.e., HDMT> or =90% accuracy), whilst 95% of the sample obtained perfect scores. Clinicians can therefore be confident that, in the absence of severe dementia or amnesia, HDMT scores below standard cutoffs are unlikely to be solely attributable to HIV-associated cognitive impairment. |
