Assessing learning and memory among patients with pediatric brain tumor (PBT): a comparison of measures

Child Neuropsychol. 2023 Jul 3:1-12. doi: 10.1080/09297049.2023.2229026. Online ahead of print.ABSTRACTPatients with pediatric brain tumor (PBT) can have memory deficits due to tumor location, medical complications, and treatment. The main objective of this study was to investigate whether the California Verbal Learning Test-Children's Version (CVLT-C; 1994) and briefer Child and Adolescent Memory Profile (ChAMP; 2015) similarly identify such deficits. Seventy-five patients with PBT ages 8-16 (x‾ = 13.1 years, SD = 2.1) were administered the ChAMP or CVLT-C. Rote verbal learning, long-term retrieval, and recognition were analyzed using standardized z-scores. Analyses of differences between measures did not reach statistical significance. Both measures indicated significant downward shifts across free retrieval trials from normative means, with scores approximately 1/3 (ChAMP) to 1/2 (CVLT-C) SD below means across learning and long-term retrieval trials. Scores on recognition trials did not differ significantly from the normative mean. Post-hoc analyses using a subset of the sample who received cranial irradiation (n = 45) similarly found no significant differences between memory measures. Additional post-hoc examination of proportion of participants falling within or below the "below average" range (≤8th percentile) revealed comparable performance between the two measures, whereas the proportion of participants falling at or below 1.5 SDs below the mean on retrieval trial...
