Although clinicians who work in adolescent inpatient settings often utilise the principles of dialectical behaviour therapy (DBT) to support young people, DBT itself is usually a community treatment modality.  This US study (an RCT using a historical control) including over 400 participants found that a formal inpatient DBT programme reduced the number of suicide attempts, use of restraints, number of days people were hospitalised and that it saved $251,609 on staff time for constant observation.
