Purpose: Youth living with human immunodeficiency virus (HIV) account for over one third of new HIV infections and are at high risk of adverse psychosocial, everyday living, and health outcomes. Human immunodeficiency virus-associated neurocognitive disorders (HAND) are known to affect health outcomes of HIV-infected adults even in the era of combination antiretroviral therapy. Thus, the current study aimed to characterize the prevalence and clinical correlates of HAND in youth living with HIV.

In the present study, clinical correlates of performance on one such measure (i.e.
View Article and Find Full Text PDFThe present study provides supplemental data for the Repeatable Battery for the Assessment of Neuropsychological Status (Randolph, 1998) by reporting base rate data on discrepancies between subtests of this measure. These discrepancies are organized by general level of ability and include both age and education corrections. The data come from the Oklahoma Longitudinal Assessment of Health Outcomes in Mature Adults study and include cognitive performances of 718 community-dwelling older adults.

Regression-based prediction formulas, which use initial test performance and demographic variables to predict follow-up test performance, have been utilized with patient and healthy control samples. Comparisons between predicted and observed follow-up performances can assist clinicians in determining the significance of change in the individual patient.

The current study examined the standard scoring criteria for the Figure Copy and Recall subtests of the RBANS and compared them to a modified set of scoring criteria in two samples. In both a large community dwelling sample of older adults and in a mixed clinical sample, the original scoring criteria consistently led to lower scores than the modified criteria.

The data presented are based on the performances of a sample of 718 community dwelling older adults. These findings offer the possibility of increased sensitivity at detecting clinically significant differences that might not be identified when relying on base rate data from a greater age range.

Several statistical formulas are available to assist in this determination, but they rely on access to test-retest stability coefficients and practice effect values. The current study presents data on these psychometric properties of the RBANS in a large community dwelling elderly sample.
View Article and Find Full Text PDFIdentification of clinically significant change in performance over time on neurocognitive tests is an important aspect of neuropsychological evaluation; however, scant published empirical data exists to guide the clinician in determining the significance of psychometric change across clinically relevant retest intervals. The present study presents base rate data of RBANS score discrepancies in a user-friendly manner based on the performances of a large sample (n=283) of community-dwelling older adults. Data for 1- and 2-year retest intervals are presented in a tabular form that can be used as a convenient reference.
