MST - the treatment proven to decrease crime, violence and substance abuse

Something that sets MST apart from some other treatments is that it has evidence—concrete evidence—from tests and studies. There have been three decades of research that confirms MST reduces criminal activity and out-of-home placements for violent and chronic offenders.

results are long-lasting

Results show:

  • long-term re-arrest rates reduced by 25-70 percent
  • out-of-home placements reduced by 47-64 percent
  • families functioning much better
  • decreased substance use
  • fewer mental-health problems for serious juvenile offenders

And MST’s positive results are long lasting

A 14-year follow-up study by the Missouri Delinquency Project showed youths who received MST had:

  • up to 54 percent fewer re-arrests
  • up to 57 percent fewer days of incarceration
  • up to 64 percent fewer drug-related arrests
  • up to 43 percent fewer days on adult probation

A 22-year follow-up study by the Missouri Delinquency Project showed youths who received MST had:

  • up to 36 percent fewer felony arrests
  • up to 75 percent fewer violent felony arrests
  • up to 33 percent fewer days in adult confinement
  • up to 38 percent fewer issues with family instability (divorce, paternity, child support suits)

MST is committed to continuing its program evaluation and has a quality assurance program that provides all MST programs around the world with tools to assess the adherence of therapists, supervisors and organizations to the MST model.
