Where have I heard that before? A validity study of source memory indices from the California Verbal Learning Test - Second edition.
CLINICAL NEUROPSYCHOLOGIST(2020)
摘要
Objective: We investigated the construct and criterion validity of the source memory (SM) indices within the California Verbal Learning Test-II (CVLT-II). Method: Participants included 77 individuals with HIV-associated neurocognitive disorders (HAND+), 287 HIV + neurocognitively normal individuals (HAND-) and 203 seronegative HIV comparisons (HIV-). CVLT-II SM impairment status (normative scores <= 1 standard deviation) was determined using Total Across-List Intrusions and Source Recognition Discriminability (d '). Participants also completed a comprehensive neuropsychological battery, assessments of everyday functioning and experimental measures of SM. Results: CVLT-II SM impairment was significantly associated with increased errors on experimental SM measures and lower scores on measures of passage recall and executive functions, but not visuospatial skills. In a logistic regression controlling for clinicodemographic factors, CVLT-II SM impairment was a significant independent predictor of HAND, with the HAND + group showing higher rates of SM impairment than both the HAND - and HIV - groups. Finally, CVLT-II SM impairment was significantly related to a composite measure of everyday functioning, but this effect disappeared after adjusting for covariates. Note that, the overall pattern of findings across this study also held when CVLT-3 normative standards were applied to the SM indices. Conclusions: Results provide initial support for the construct and criterion validity of a CVLT-II SM index in the setting of HIV disease. Future studies should examine the validity of CVLT-II SM variables in other neuropsychological populations.
