The oral and written narrative language skills of adolescent students in youth detention and the impact of language disorder

Unmet language and literacy needs are common among young people who are involved with youth justice systems. However, there is limited research regarding the functional text-level language skills of this population with regard to narrative macrostructure (story grammar) and microstructure (semantics and syntax) elements. In this study, we examined macrostructure and microstructure elements in the oral and written narrative texts of 24 adolescent students of a youth detention centre. The students, who were aged 14- to 17- years, were all speakers of Standard Australian English, and 11 (46%) students met criteria for language disorder (LD).
