“…In a recent epidemiological study, more than two thirds of children reported at least one traumatic event by sixteen years of age, suggesting that potentially traumatic events are fairly common in childhood and adolescence [22][23][24][25] . Other well-known risk factors include parental psychopathological disorders [26] , domestic violence and bullying [27,28] , physical abuse [29] , having a chronic paediatric illness [30] , poverty and material hardship [31,32] .
