19 Processing Speed and Academic Fluency in Childhood Survivors of Acute Lymphoblastic Leukemia Treated with Chemotherapy Only

Objective:The purpose of this study using archival data was to examine processing speed (PS) and its relation with academic fluencies in children who were diagnosed with, and treated with chemotherapy for, acute lymphoblastic leukemia (ALL) before vs. after five years of age.

Zusammenfassung:Objective:The purpose of this study using archival data was to examine processing speed (PS) and its relation with academic fluencies in children who were diagnosed with, and treated with chemotherapy for, acute lymphoblastic leukemia (ALL) before vs. after five years of age. Chemotherapy is the first-line treatment for childhood leukemias, and the impact of cancer treatment on academic and global functioning may include a steady decline in functions over time (Baron & Rey-Casserly, 2013). Specifically, this research initiative examined age and gender factors in PS and academic fluencies in this population.Participants and Methods:Sixty-eight participants (39 M, 29 F; mean age 10.6 years) diagnosed with ALL and who were previously treated with chemotherapy were included. Thirty-seven participants (23 M, 14 F) were 5 years of age at diagnosis and treatment. Participants ranged in age from 6 to 17 years at the time of their neuropsychological evaluation. Participants were given the WISC-V (PS subtests) and WJ-IV academic fluencies (math and reading). To evaluate research questions and hypotheses, correlational tests, independent samples t-tests, and analyses of variance (ANOVA) were used. Results at the p< .05 level are reported.Results:There were significant correlations between PS and WJ math fluency (r=.510) and reading fluency (r=.392). Independent samples t-test analyses revealed that children who scored below 85 (standard score) on PS composite score demonstrated poorer performance on WJ math fluency (t(60)=-3.971, p=.000, d=1.065) and reading fluency (t(56)=-3.041, p=.004, d=0.896) compared to children whose PS scores were > 85. For children whose PS scores were
