“…Some researchers found a high prevalence of specific language impairment in psychiatric samples (Beitchman, Nair, Clegg & Ferguson, 1986;Cohen, 2007) while others found an association between preschool patterns of language development and future crime engagement (Stattin and Klackenberg-Larsson, 1993). Rates of language impairment are reported to reach 24% to 65% in samples of children identified as exhibiting disruptive behaviors (Benasich, Curtiss, & Tallal, 1993) and 59% to 80% of preschool-and schoolage children identified as exhibiting disruptive behaviors also exhibit language delays (Beitchman, Nair, Clegg, Ferguson, & Patel, 1996;Brinton & Fujiki, 1993;Stevenson, Richman, & Graham, 1985). High comorbidity estimates are also reported between language difficulties and diagnoses of ADHD (Cantwell & Baker, 1991;Kim & Kaiser, 2000).…”
