In a 2001 survey 99% of adolescents reported exposure to at least one traumatic event in the previous year. Of these, around 20% developed Post Traumatic Stress Disorder (PTSD).
The study revealed that:
32% of boys and 35% of girls had witnessed a family member being killed or injured in an assault or motor accident.
43% of boys and 26% of girls had been robbed or mugged.
Almost half the teenagers with symptoms of stress disorder were frequently using dagga or alcohol.
