Multisystemic Therapy-Psychiatric – The overriding goal of Multisystemic Therapy (MST) is to keep adolescents who have exhibited serious clinical problems (e.g., drug use, violence, severe criminal behavior) at home, in school, and out of trouble. Multisystemic Therapy–Psychiatric (MST–P) adapts the principles of MST by treating youths with psychiatric problems within their home environment and intervening in the systems, family, and caregiving environment. Treatment aims to reduce the risk of self-harm (including suicide), depression, and anxiety as well as externalizing symptoms such as drug use and criminal behavior among youths at risk of out-of-home placement due to serious behavioral problems with co-occurring mental health symptoms.
