Among the general Canadian population, the most common mental disorders are depression, anxiety, posttraumatic stress disorder, psychosis and substance use disorder.
A systematic review examining several studies found that the most common mental disorders in first-generation immigrants are depression, anxiety and posttraumatic stress disorder (Close et al., 2016). The prevalence of these mental disorders varies widely based on complex factors, including pre-immigration experiences.
According to a recent systematic review on mental disorders among refugees, the prevalence rates of depression, anxiety and posttraumatic stress disorder were typically 20% and over (Ibid.). Some studies have also found higher rates of psychosis and substance use problems among immigrants and refugees than in the general population (Durbin , Lin, Taylor, & Callaghan, 2011; Parrett & Mason, 2010; Kirmayer et al., 2011a; Kroll et al., 2011; Anderson et al., 2015; Brandt, et al., 2019).
Again, it is important to keep in mind that the prevalence of mental disorders varies greatly between and among immigrant and refugee subpopulations.
