“…Whilst a definitive cut off age for the definition of PSD has not been agreed, it has generally been applied to children of approximately age 8 and above. This is logical given that speech acquisition is generally considered to be complete by this age (Dodd, Holm, Hua & Crosbie, 2003;James, 2001;Smit, 1993aSmit, , 1993b. Moreover, Shriberg, Fourakis, Hall, Karlsson, Lohmeier, McSweeny et al (2010) justify a cut off between age 8 and 9 on the basis that children whose speech disorder continues beyond this age are small in number but more at risk for long term persistence and associated sequelae, sometimes into adulthood.…”
