During Stage 1, adolescents in all intervention conditions will receive standard detention services, which include education and health care. In addition, youth assigned to the ESAU condition will receive the standard mental health and substance abuse services offered in the detention (mainly psychoeducational in nature). Youth assigned to the MDFT-CS intervention will not receive standard mental health/substance abuse services provided by the detention center, as these youth will be assigned a MDFT therapist who will address their mental health and substance abuse issues needs.
