Background: On the 3rd of May 2016, a mandatory evacuation order was issued for Fort McMurray and surrounding communities due to raging wildfire that threatened lives and property. Objectives: This study assesses the prevalence rates for likely Post-Traumatic Stress Disorder (PTSD), Major Depressive Disorder (MDD) and Generalized Anxiety Disorder (GAD) in residents of Fort McMurray six and 18 months after a wildfire and to determine the demographic, clinical and other predictors of these disorders in the respondents. Methods: The PTSD Checklist for DSM 5 Part 3, the PHQ-9 and the GAD-7 were used to assess the presence or absence of probable PTSD, MDD and GAD respectively in Fort McMurray residents in this cross sectional survey which employed random selection procedures. Results: At six months, 486 Fort McMurray residents completed the survey. The one month prevalence rate for likely PTSD, MDD and GAD were elevated at 12.8%, 14.8% and 19.8% respectively. While controlling for other factors in the logistic regression model, patients who reported they received no support from family and friends were 9.5 , 12.75 and 3.45 times respectively more likely to have a likely PTSD, MDD or GAD compared to patients who reported they had absolute support of family and friends. The rates of PTSD, MDD and GAD are expected not to vary significantly with the 18 month data currently being compiled for analysis. Conclusion: Our study has established that while support from family/friends following wildfires may be protective against likely PTSD, MDD and GAD.
