In 2012, more than 80,000 cases of HIV infection were recorded in the Southern Chinese minority autonomous region of Guangxi Zhuang, where the occurrence of HIV-associated dementia remains high. The International HIV Dementia Scale is a relatively simple-to-administer screening scale for HIV-associated neurocognitive disorders. However, clinical experience in utilizing the scale with large Chinese samples is currently lacking, especially among individuals with limited formal schooling. In this study, a full neuropsychological evaluation the gold standard was conducted to identify the incidence/prevalence of HIV-associated neurocognitive disorders in a socioeconomically underdeveloped region of Southern China and to locate the optimal cut-off scale value using receiver operating characteristic curves. The highest Youden index of the scale was 0.450, with a corresponding cut-off point of 7.25. The sensitivity and specificity were 0.737 and 0.713, respectively. These results suggest that the scale is an effective and feasible screening tool for HIV-associated neurocognitive disorders in poorer regions of China with fewer well-educated residents.
