As a result of acts of crime and violence, children detained in our juvenile correctional facilities require strong interventions. Nationally, there are over 105,000 juveniles in private and public facilities. Employment in juvenile institutions is a small part of total employment in the overall State and local government correctional field. Mental health professionals working within the juvenile justice field treat large numbers of adolescents, many of whom are violent, truant, run-aways, and/or abusing illegal substances. This updated edition includes DSM-5 and ICD-10 diagnostic codes.
