Research & Publications

Research Summary

Dr. Zabel’s research focuses upon the adaptive and neuropsychological functioning of individuals with congenital and acquired disorders of the brain’s white matter, with particular emphasis on persons with hydrocephalus, spina bifida, Sturge-Weber syndrome, and cerebral palsy. Recent publications have focused on the executive components of medical self-care, self-management, and transition into adulthood. 

Within Kennedy Krieger, Dr. Zabel and his collaborators have instituted a system of internet-based clinical data collection to facilitate efficient parent- and teacher-report of behavior. Outside of Kennedy Krieger, Dr. Zabel and his collaborators have created the Kennedy Krieger Independence Scales–Spina Bifida Version (KKIS-SB) to measure the executive components of spina bifida–related health care. The KKIS-SB and other instruments have been accrued into a nationally available online dashboard of parent, teacher, and self-report questionnaires to help facilitate the systematic provision of evidence-based spina bifida–related care.
