The program has been fairly well researched since 1997, which is when the first group was run by Dr. Westwood and Dr. David Kehl. In 2012, we brought on a researcher from the U.S., who's now based at the University of British Columbia, Dr. Dan Cox. He's now conducting the outcome research, essentially, on our program. We deliver questionnaires pre-program and afterward, at three, 12, and 18 months after the program.
We're using a suite of different diagnostic measures. In 2012, we switched to using the OQ-45—outcome questionnaire 45—which is in line with what Veterans Affairs is using, but we're also measuring depression through Beck's depression inventory—a PTSD checklist, essentially—and other measures of quality of life.
We've just recently performed the analysis on our 18-month data because we run small groups, so it takes a while to get to a significant sample size. We've seen significant reductions in post-traumatic stress and depression symptoms and the frequency and severity of suicidal thoughts, and we see an increase in quality of life.
