Procedures
The screening protocol was developed as a clinical program by the authors, which include a pediatric psychologist, two pediatric neuropsychologists, a pediatric hematologist, and a clinical psychometrist. This associated study was approved by the Institutional Review Board and appropriate informed consent and assent were obtained prior to study enrollment. Patients completed the screening program regardless of study participation. The psychologist completed the semi-structured interview with the patient’s caregiver while the clinical psychometrist administered the complete battery of neurocognitive assessments to the patient.
