I think there are two parts to your question.
The participants absolutely said they benefited from participating in the play. It was another way to be witnessed by the Canadian public. When you feel witnessed, heard and understood, the research on mental health, PTSD and trauma would suggest you're better able to process things. Just having a stage and a platform to be seen and heard was beneficial to the participants.
What it did for audience members, both family and veteran, is let them know that what they were going through was normal—that those families were not the only ones with their son, daughter or loved one living in their basement suite, or not leaving their basement suite for several months. That allowed them to feel more comfortable with talking about their story and seeking help, sometimes just by approaching one of us involved in the play immediately following the play, or following up with one of the resources we shared online after the play, like a link to the Veterans Transition Network or the veterans transition program.
That's what we saw and how we helped, if that answers your question.
