John R. Knight
John R. Knight is an Associate Professor of Pediatrics at Harvard Medical School (HMS) and the Associate Director for Medical Education at the HMS Division on Addictions. In 1999, he founded the Center for Adolescent Substance Abuse Research (CeASAR) and its companion outpatient clinic, the Adolescent Substance Abuse Program (ASAP). CeASAR and ASAP were the first programs of their kind to be located at a children’s hospital. He is best known as the clinical scientist who developed and validated the CRAFFT substance abuse screen for adolescents. In 2008 he was named the inaugural incumbent of the  Boston Children’s Hospital Endowed Chair in Developmental Medicine The CRAFFT Screening Test. Knight and his colleagues first assessed other brief substance abuse screening tests. They then developed a new brief screener known as “CRAFFT” that was shown to be valid, reliable, developmentally appropriate for adolescents, and practical for use in busy pediatric offices. CRAFFT has since become the American Academy of Pediatrics’ recommended standard of care in its policy statements, and it is recommended in their Bright Futures health supervision visit as the alcohol and drug-use assessment.
