Title	Hopkins verbal learning test -revised: standardization data of percentage retention and comparison of retention rates with logical memory subtests of the wechsler memory scales -revised
Abstract	The purpose of this study was to determine the utility of the Hopkins Verbal Learning Test-Revised (HVLT-R), as a brief neuropsychological screening measure of immediate and delayed verbal memory in a mild traumatic brain injury sample. From an archival database, the neuropsychological test scores of a total of 698 subjects with a recent mild-TBI were selected for the study. Age and education effects were analyzed with nonparametric measures. Correlations between the neuropsychological tasks were conducted. Post-hoc exploratory analysis involved the creation of frontal lobe superior and impaired groups based on performance on two frontal lobe tasks: the Controlled Oral Word Association Test (COWAT) and Trails B from the Trail Making Test A and B. Independent sample t-tests were conducted to analyze the groups. Results suggest that several narrow age groups published in the HVLT-R's test manual were not found with the current head-injured sample. In contrast, three age group categories emerged from the results: 18-29 years; 30-69 years; and 70+ years. Results of education level indicated no significant difference between subjects with a high school diploma or equivalency and subjects with less than a high school education. However, both groups significantly differed from subjects with more than a high school education. The HVLT-R was compared with the Logical Memory subtest from the Wechsler Memory Scales-Revised (WMS-R). Although the correlations between the measure's various tasks were moderate, the HVLT-R identified a much higher number of subjects in the impaired range. Exploratory analysis involved creating groups based on the top and bottom quartile of individuals who had taken the COWAT and Trails B, two frontal lobe tasks. The comparison of the HVLT-R and Logical Memory on the established "frontal lobe superior" and "frontal lobe impaired" groups revealed that both measures were able to identify clients with impaired frontal lobe functioning and differentiate them from individuals with intact frontal lobes. The first trial of the HVLT-R was also correlated with another test of focused attention and immediate memory, the Digit Span subtest of the WMS-R. Results suggested a moderate correlation between the tasks.
