PTSD after road accidents

Prevalence in road traffic accident survivors

What is prevalence of PTSD following road traffic accidents?

Prevalence represents the overall proportion of individuals in a population who have the disorder of interest. It is different from incidence, which represents only the new cases that have developed over a particular time period. Point prevalence is the proportion of individuals who have the disorder at a given point in time. Period prevalence is the proportion of individuals who have the disorder over specific time periods. Lifetime prevalence is the proportion of individuals who have ever had the disorder. Lifetime morbid risk also includes those who had the disorder but were deceased at the time of the survey.

What is the evidence for the prevalence of PTSD?

Moderate quality evidence finds the overall prevalence of PTSD in people after a road traffic accident is around 22.25%. Rates were highest in females, in Black people, in people living in the USA, and in people without a college education.

The prevalence of PTSD in children and adolescents after road traffic accidents is 19.95%. Rates were highest in females and in studies located in children living in the UK.
