One of the first and most common barriers is not understanding that the symptoms the person is dealing with are related to a mental health problem. Often the symptoms start to come up as sleep difficulties or difficulties with irritability or concentration, so the person doesn't understand what they're dealing with and often blames themself. I think it goes back to what other witnesses are saying, that helping the public understand and recognize appropriately what is or is not PTSD is very important.
The second issue is around the impact on work. If the person is diagnosed with PTSD, what happens to their career advancement at work? Are they judged by other people at work? That's a major barrier that's been shown in military personnel.
The third barrier is not necessarily a barrier; it's the attitude that they want to handle the problem on their own. That is something we're supporting by creating self-help cognitive behaviour therapy so people can access help more readily.
There are three main barriers. One is not understanding that they might be dealing with a mental health issue; the second is the impact and stigma around work; and the third is not necessarily a barrier, but a wish to try to handle the problem on their own.
