“…About 3% of the adult population in England, for example, has PTSD at any one time (McManus, Meltzer, Brugha, Bebbington, & Jenkins, 2009). Lifetime prevalence is between 1.9% (Alonso, Angermeyer, & Lépine, 2014) and 8.8% (Ferry et al, 2010), but this rate doubles in populations affected by conflict (Steel et al, 2009) and reaches more than 23% in survivors after an earthquake (Dai et al, 2016).
