“…Forty-four of the 51 studies utilised the standard version of the YFAS, of which six had been converted to and validated in the following non-English languages: Italian (n = 6) (20,40,(51)(52)(53)(54) , French (n = 3) (36)(37)(38) , German (n = 3) (15,64,67) , Spanish (n = 4) (17,49,50,73) , Arabic (n = 1) (76,82) , Chinese (n = 1) (42) and Turkish (n = 1) (71) . Three studies used the shorter version of the YFAS, referred to as the modified YFAS (mYFAS), which comprises nine questions rather than the standard 25 items (45,60,72) ; these studies were larger populationbased surveys.…”
