Prior research has demonstrated the reliability and validity of the Neurological Predictor Scale (NPS) in relation to childhood brain tumor survivor outcomes; however, its use has not been examined in adult long-term survivors. The current study examines the concurrent validity of the NPS with long-term intellectual and adaptive outcomes in adult survivors of childhood brain tumors relative to individual variables alone. A total of 68 adult survivors of childhood brain tumors (M = 24 years old, SD = 4) almost 16 years post diagnosis (SD = 6) completed intellectual evaluations using the Wechsler Abbreviated Scale of Intelligence (WASI). Survivors' adaptive functioning skills were assessed via informant structured clinical interviews (SIB-R). NPS scores were computed from data acquired from medical records. The NPS was significantly associated with intellectual (R2 = 0.208, p < .05) and adaptive outcomes (R2 = 0.30, p < .05) over and above individual risk factors. Approximately 18% of long-term survivors were identified as impaired in intellectual outcomes, and 29% were identified as impaired in adaptive functioning in everyday life skills. The NPS quantifies the cumulative effects of treatment and neurological sequelae experienced by both short- and long-term survivors of childhood brain tumors. It is a useful and easy measure to employ in clinical research that focuses on quantifying the neurological risk factors associated with long-term intellectual and adaptive functioning outcomes in adult survivors of childhood brain tumors.
