I recently attended a workshop on Suicide Prevention Training here at UBC organized by some folks in the BEd program. It was delivered in “QPR” format: Question, Persuade, Refer. They acknowledged that it was introductory, and it would be beneficial to continue educating yourself in this area, but it was a really great 2-hour intro. I would definitely recommend attending something like this, perhaps for a Pro-D activity, and the one through UBC was fantastic!
