| Sumario: | Objective: To investigate the methylphenidate (MPH) response rate among childhood survivors of acute lymphoblastic leukemia (ALL) and brain tumors (BTs) and to identify predictors of positive MPH response.Methods: Cancer survivors (N = 106; BT = 51 and ALL = 55) identified as having attention deficits and learning problems participated in a 3-week, double-blind, crossover trial consisting of placebo, low-dose MPH (0.3 mg/kg), and moderate-dose MPH (0.6 mg/kg). Weekly teacher and parent reports on the Conners' Rating Scales were gathered.Results: Following moderate MPH dose, 45.28% of the sample was classified as responders. Findings revealed that more problems endorsed prior to the medication trial on parent and teacher ratings were predictive of positive medication response (p < .05).Conclusions: MPH significantly reduces attention problems in a subset of childhood cancer survivors. Parent and teacher ratings may assist in identifying children most likely to respond to MPH so prescribing may be optimally targeted.
