Dr. Norris is involved in medical research exploring treatment and behavioural outcomes in youth with complex feeding and eating disorders. In addition to studies examining adjunctive use of medication for EDs, he has investigated epidemiological rates of EDs in Canada, treatment studies that have utilized varying intensities and innovative measures to study outcomes in EDs, and investigations that examine medical complications of EDs. In addition to this area of study, Dr. Norris also collaborates with other Canadian investigators on studies that involve vulnerable adolescent populations.

BRAVA: A randomized controlled trial of a brief group intervention for youth with suicidal ideation and their caregivers
16/07/2025
This randomized controlled trial evaluated BRAVA, a six‑week virtual group intervention designed to support adolescents with mild to moderate suicidal ideation and their caregivers. The study found that while both the intervention and control groups showed improvements, BRAVA participants demonstrated greater reductions in perceived stress, depression, and anxiety—benefits that were maintained at three‑month follow‑up. These findings suggest that BRAVA may offer meaningful support for youth experiencing suicidal ideation.
