More than 1 in 3 Fort McMurray youth show signs of PTSD following 2016 wildfires

Long-term Impacts of disaster on youth mental health not often considered, and underline the need for ongoing mental health support, researchers say.

When wildfires raged through Fort McMurray in May 2016, the impact to the community was devastating: Nearly 88,000 people were evacuated from the area and more than 1,900 family homes were lost. While residents have returned to the community and many of the homes have been rebuilt, a new U of A study is highlighting the long-term psychological impacts of the disaster, especially on the community's youth.

In the study, published in the journal Frontiers in Psychiatry, professor Peter Silverstone, adjunct professor Matthew Brown and a team that included members of the Fort McMurray Catholic and public school systems surveyed 3,252 students in grades 7-12 a year and a half after the fires tore through the community. The survey measured levels of PTSD, depression, anxiety, use of drugs, alcohol and tobacco, quality of life, self-esteem and resilience in students. It also compared the psychological impact on students who were living in Fort McMurray at the time of the fires, and those who moved to the community afterwards.

The results revealed that 37 per cent of Fort McMurray students showed signs of PTSD, which was about twice to three times the expected level. About 17 per cent showed indications of depression (twice the normal level), and many students showed signs of significant anxiety, including 15 per cent demonstrating alcohol or substance abuse issues. In total, nearly half of all students exhibited signs of suffering from at least one significant psychological problem.

"The study shows a clear link between low resiliency and elevated mental health symptoms," Brown said. "This is consistent with previous studies as well. From this, we expect that improving individuals' capacity to recover quickly from difficulties would reduce their susceptibility to mental health problems."

Both Brown and Silverstone agree the findings are concerning and emphasize the need for long-term mental health supports for youth following a disaster. They believe such supports should be an integral part of rebuilding a community.

"We know that most mental health problems start in the teens and can continue for many years or even decades. It impacts families as well as the individual throughout their lives, such as their ability to work or go to school," Silverstone said. "Unfortunately what happens is once the disaster moves out of the news cycle, it can be very hard to raise the issue again because things move on, but the trauma and impacts haven't."

Those impacts, Silverstone says, can be wider reaching than we think. One of the most surprising findings of the study was that youth who were not directly impacted by the wildfires, and had in fact moved to the community after the disaster, were found to have higher than normal levels of PTSD, anxiety and other trauma indicators.

"It was a completely unexpected finding," Silverstone said. "It suggested to us that there was a much more widespread change across the entire community after the fires."

"The whole community is suffering."

Building resilience

Helping children build a higher resilience to stress is one of the ways that suffering can be addressed, and ideally reversed, Silverstone says. It's part of the impetus behind a partnership with the public and Catholic school boards in Fort McMurray to bring in a new program designed to help children develop tools and strategies to better manage stress.

"People sometimes don't realize that if you give an intervention to one person, you don't just help that one person, you are helping them and their friends," Silverstone said. "Often that person's friends are worried about them and don't know what to do and when you give someone those resilience tools, you see widespread positive benefits."

Building on previous work Silverstone did with youth in Red Deer, and based on a school-based depression prevention program from Holland called "At Full Power," the Fort McMurray program will be initially offered to students in grades 7 to 9 and help them analyze their thoughts, emotions and feelings. It will involve eight to 10 classes during regular school hours focusing on 16 different cognitive behavioural interventions. The program is scheduled to start in early 2020.

"Preventing kids from getting problems throughout their lives is really important. And if we intervene in schools, we can do that," said Silverstone.

"Of all the research I've done, covering many areas, I think this focus on prevention is the most important."

The study was supported in part by the Canadian Institutes of Health Research, the Canadian Red Cross, and Alberta Innovates Health Solutions.
