Background Radiotherapy is associated with an increased survival rate in children with brain tumors, but also with cognitive decline. This study examined the time‐dependent effects of radiation treatment on adaptive functioning in children with brain tumors. The potentially mediating effects of attention span (Trial 1 of the Rey Auditory Verbal Learning Test [RAVLT]) assessed within 7 years of diagnosis were explored. Procedure Twenty‐two children treated with cranial radiation for third ventricle or cerebellar tumors were included in this archival study. The mean age at diagnosis was 7.62 years (SD = 4.78) and 10.16 years (SD = 3.83) at evaluation. We examined the extent to which auditory attention span was able to mediate the relationship between time elapsed since the initiation of radiation treatment (M = 2.43 years; SD = 2.37) and adaptive functioning (Vineland Adaptive Behavior Scales [VABS]). Results Attention span was found to mediate the relationship between time since the initiation of radiation and daily living skills. These findings were shown to be specific to attention and not a reflection of generalized neuropsychological decline, nor were they a result of increasing time since diagnosis in and of itself. Conclusions The results of this study suggest that time since radiation may directly decrease attention and poor attention in turn may be associated with lower adaptive functioning on tasks of daily living.
