Background: Traumatic brain injury (TBI) is common among children. However, their caregivers' knowledge and understanding of symptoms may influence how the injury is managed. Primary objective: To investigate the knowledge of New Zealand (NZ) parents about TBI and concussion. Method and procedures: Parents (n = 205) of children aged 5–13 years completed a pen-and-paper or online survey containing questions examining their knowledge of TBI terminology, TBI symptoms and knowledge about concussion management. Main outcomes and results: A high proportion (61%) of parents did not think that a concussion was the same as a brain injury. Loss of consciousness (LOC) was the most endorsed symptom of TBI. However, 69% of participants were aware that TBI could occur without LOC. On average, parents correctly identified 19.5 (67.3%) of the 29 symptoms of TBI, but also identified 2.0 (11.9%) of the 17 distractor symptoms as being TBI related. Demographic factors and experience of TBI/concussion were associated with TBI symptom identification accuracy and concussion knowledge. Conclusions: Further education of parents is needed to ensure they recognise the signs and symptoms of concussion/mild TBI so that they can make informed decisions on how best to manage their child's injury.
