I don't know whether it's as high as 60%. I know that in the under-18s it's in a much smaller proportion. In the older population we see a lot of comorbid history of abuse and post-traumatic stress. A lot of our patients really benefit from dialectical behavioural therapy, as well as a unique treatment that some of our therapists use, EMDR, which is very effective in post-traumatic stress.
I don't know the exact percentage in our program, but I would say it was probably at least 40% to 50%.
