Compared to younger youth and middle-aged and older adults, older youth and young adults (16–25 year olds) are more likely to experience serious mental health challenges, including schizophrenia, bipolar, and major depressive disorders.1 These young people are at increased risk for high school dropout (or “pushout”), unemployment and under-employment, poverty, housing instability, homelessness, justice involvement, and suicide.2 They are also least likely to utilize mental health services, which tend to feel stigmatizing, incongruent, and ineffective to young people. Accessible, attractive, and effective services spanning both child and adult sectors are needed to engage this unique population. To address these challenges, Thresholds, the largest community mental health provider in Illinois, successfully developed and implemented two multidisciplinary sister teams serving young people within a Medicaid and commercial fee-for-service insurance billing environment.
