The manual says "71% 4 year olds with DLD score in the Highest Risk category; See Table 4.25 - 4.30 for more information" Some psychometric data is available here https://journals.sagepub.com/doi/full/10.1177/1534508411413760 This test was specifically designed to differentiate dialect from disorder. It can be used to assess diagnostic risk for both MAE and NMAE speakers. --> commentary by Owen Van Horne; not taken from the web.

There's also a thesis published that suggests that the 5 item test is broadly fine for a screening... But the psychometric tools are not modern in either paper. no information available that I am aware of
