Language disorder and internalizing mental health problems in youth offenders: A systematic review.

What is already known on this subject The markedly high rates of language disorder in youth involved in the justice system have been widely reported. It is also known that externalizing mental health problems often bring youth in contact with the justice system. Though there is some information about the prevalence of internalizing mental health problems in this population, the co-occurrence of language disorder and internalizing mental health problems has not been examined as widely. What this study adds to existing knowledge This study aimed to identify the frequency of co-occurrence of language disorder and anxiety and/or depression in youth offenders. Although the results did not support a significant relationship between language disorder and internalizing mental health problems in this population, results of the review provide evidence of heightened rates of both. This study also provides a summary of the various measures used to assess language and internalizing mental health in youth offenders across the eight studies included in this review. What are the potential or actual clinical implications of this work? It is possible that the tests and sub-tests used to identify language disorders and internalizing mental health problems were not sensitive enough to identify the full extent of youth offenders' needs. Identifying the presence of language disorders and internalizing mental health problems and recognizing the impact these may have on the communication and behaviours of an individual can better inform staff and therapists as they engage and interact with youth in the justice system.
