Comparing the Open Trial – Selective Reminding Test results with the California Learning Verbal Test II in multiple sclerosis

ABSTRACTWe compared the California Learning Verbal Test II (CVLT II) and the Open Trial-Selective Reminding Test (OT-SRT) in assessing learning in persons with Multiple Sclerosis. One-hundred and twelve participants with multiple sclerosis performed the OT-SRT and the CVLT II on two different days. All participants completed additional cognitive tests assessing information processing speed (IPS), working memory (WM), and executive functions (EF). By definition, all participants were identified as having impaired learning on the OT-SRT (i.e., z score <−1.0); however, only 38 participants (33.9%) were identified as having impaired learning on the CVLT II (i.e., a z score <−1 total correct responses trials 1–5). The sample was thus divided into two groups, those who failed both tests (Fail-2) and those who failed only one (Fail-1). The Fail-2 group showed poorer performance on EF, WM and IPS in comparison with the Fail-1 group. On the CVLT II, the Fail-1 group showed a significantly greater improvement betwe...
