Multisystemic therapy (MST) is a highly individualised family- and home-based treatment that has successfully served as a clinically effective and
cost-effective alternative to out-of-home placements (e.g., incarceration,
psychiatric hospitalisation) for youth presenting serious clinical problems.
MST clinical procedures are reviewed and two extensive case summaries
are used to explicate the MST intervention process for treating serious
antisocial behaviour and modifications in that process needed to safely
and effectively serve youth presenting psychiatric emergencies.
