We are not experts in post-traumatic stress syndrome. However, I am a psychologist and my colleague is as well. One would have to validate what you're saying through research, but to my knowledge there is no way to prevent post-traumatic stress disorder. Generally speaking, you can do so for other mental health problems. So members of the Canadian Forces could certainly benefit from receiving treatment aimed at preventing any type of mental health problem, which can have a positive long-term effect. Hiring psychologists to work with the Canadian Forces to help them adopt a healthier lifestyle and mental health care would be a very good initiative.
