Effect sizes ranged from −0.09 to 0.06 across the index scores, from −0.11 to 0.11 across the recall scaled scores, from −0.15 to 0.06 across the recognition scaled scores, and from −0.18 to 0.29 across the error and process scaled scores, indicating small changes in performance across forms. Therefore, it is unlikely that performance will vary across the two forms greatly due to experience with the test. It is important to note that when the same form is administered, memory tests show practice effects (i.e., performance improvement related to prior experience with taking a test) for a long time after administration, with patients recalling information for months to years after administration (Goldberg, Harvey, Wesnes, Snyder, & Schneider, 2015).
CAUTION 1.1
Memory and learning measures are particularly susceptible to practice effects. Practice effects can be observed for more than 6 months.
COMPREHENSIVE REFERENCES ON TEST
The most detailed and comprehensive information for each edition of the CVLT can be found in the corresponding test manual: CVLT-C Manual, CVLT-II Manual, and CVLT3 Manual. Each manual provides an overview of the test, descriptions of each condition and score, and detailed information on administration and scoring, calculating the raw scores, and deriving normative scores. Information on the theoretical underpinnings, development and standardization, reliability, validity, and interpretation are also provided. In addition, the CVLT3 manual provides an overview of the use of demographic adjustments to the CVLT3 norms.
Editions of the CVLT have been used in multiple research studies incorporated into thousands of published articles. The CVLT-C has been used to assess memory functioning in typically developing children, children with acquired disorders, such as brain tumors and injuries, and children with neurological disorders, such as epilepsy. The CVLT-II has been used to examine memory functioning in typically developing and aging adults, individuals with degenerative diseases, such as mild cognitive impairment and dementia, individuals with acquired injuries, such as stroke or traumatic brain injury, individuals with psychiatric disorders, such as schizophrenia, and other populations with suspected or known memory disorders. It is expected that more research on the CVLT3 will become available as the revision is more widely used. Rapid Reference 1.10 provides basic reference and publication information for the CVLT-C, CVLT-II, and CVLT3.
