Emerging data support the construct validity of component process variables of learning and memory within the Hopkins Verbal Learning Test-Revised (HVLT-R; Brandt & Benedict, 2001); however, the test-retest reliabilities of such measures are heretofore largely unknown. This study reveals generally modest-to-low 1-year test-retest stability for several key HVLT-R component process variables (e.g., semantic clustering) in 41 healthy, younger adults. These findings are discussed in relation to issues of clinical practice and research design in neuropsychological assessment.
