title: The Interchangeability of CVLT-II and WMS-IV Verbal Paired Associates Scores: A Slightly Different Story.
abstract: We investigated the similarity of the Wechsler Memory Scale-Fourth Edition (WMS-IV) Auditory Memory Index (AMI) scores when California Verbal Learning Test-Second Edition (CVLT-II) scores are substituted for WMS-IV Verbal Paired Associates (VPA) subtest scores. College students (n = 103) were administered select WMS-IV subtests and the CVLT-II in a randomized order. Immediate and delayed VPA scaled scores were significantly greater than VPA substitute scaled scores derived from CVLT-II performance. At the Index level, AMI scores were significantly lower when CVLT-II scores were used in place of VPA scores. It is important that clinicians recognize the accepted substitution of CVLT-II scores can result in WMS-IV scores that are inconsistent with those derived from standard administration. Psychometric issues that plausibly contribute to these differences and clinical implications are discussed.
