Multisystemic Therapy for Child Abuse and Neglect

Multisystemic Therapy for Child Abuse and Neglect (MST-CAN) is an intensive intervention for families who have recently been reported to Child Protection Services for physically abusing and/or neglecting a child between the ages of 6 and 17. An MST-trained social worker or psychologist provides home-based therapeutic support to individual families for a four to six-month period with the aim of keeping children safe and stopping physically and emotionally abusive or neglectful parenting behaviours.

Model description

Multisystemic Therapy for Child Abuse and Neglect (MST-CAN) is an intensive intervention for families who have recently been reported to Child Protection Services for physically abusing and/or neglecting a child between the ages of 6 and 17.

MST-CAN is delivered by an MST-CAN therapist (typically a social worker with a master’s level qualification) who provides the family with a tailored package of support that includes individual and family support and therapy. The therapist is available to the family on a 24/7 basis and carries a caseload of three to four families at a time. Therapists typically work with families for an average of six to nine months, and commonly see families around three times a week, although these visits will vary according to the level of need. A hybrid model of support delivered by keyworkers is also available in cases that are less severe, including those involving unsubstantiated neglect.

Referrals typically come from child protection services following concerns involving abuse or neglect occurring within the past 180 days. Child protection first contacts the family to ensure that the family is in agreement with the referral, and then refers the family to the MST team.

Within 48 hours of acceptance of the referral, the MST-CAN supervisor or the therapist assigned to the case will contact the family to explain the treatment and invite them to participate. When parents agree, a detailed intake assessment begins, which is carried out over a series of visits to the family’s home.

The primary aim of the first session is to engage family members and establish a collaborative partnership between the MST therapist, child protection services and the family. In some cases, it will become clear that the family is in crisis, so the first priority is to stabilise the family situation. If the child is out of the home at the time of referral, the MST-CAN worker will meet with foster parents or kinship carers to make sure that the child’s placement is stabilised until the child can return home.

A second aim of the initial sessions is to gain an understanding of the severity of the family’s circumstances and the multiple risks that may be contributing to the maltreating behaviour. This understanding is gained through meetings with child protection services, as well as meetings with the family.

At the beginning of the intervention, the MST-CAN worker and family work collaboratively to identify family-specific goals for positive change. These goals should be clearly linked to parenting behaviours that would be considered abusive and neglectful, with a primary aim of increasing the child’s safety. In the short term, it is expected that:

  • The parent will no longer abuse or neglect the child
  • There will no longer be a need for an out-of-home placement
  • The child will live in a safer home environment
  • Any family crises will be stabilised
  • Parents will use more effective parenting skills
  • Family relationships will improve
  • The family will have improved their network of informal supports
  • The child and parent’s mental wellbeing will improve.

By the conclusion of the intervention, it is expected that:

  • Abuse and neglect will be eliminated
  • Out-of-home placements will be prevented
  • There will be improvements in parental mental health functioning
  • There will be observable improvements in parenting behaviours.

MST-CAN therapists are trained and supervised to identify the risks associated with abuse and neglect, and are thus able to tailor the intervention to directly address these risks. MST therapists are also trained to treat a wide variety of mental health problems experienced by children and adults. MST teams are embedded well within the local system so that additional treatments, including pharmaceutical treatments prescribed by the NHS, can be used to address specific mental health conditions.

Age of child

6 to 17 years

Target population

Families who have recently been reported to Child Protection Services for physically abusing and/or neglecting a child between the ages of 6 and 17.

Disclaimer: The information in this section is as offered/supported by the intervention provider.

Why?

Science-based assumption

Child maltreatment is a major public health concern that is associated with a broad array of adverse short- and long-term outcomes for children.

Science-based assumption

Child maltreatment is multi-determined by risks associated with the child, family, school, and community.

Who?

Science-based assumption

Families where there are serious concerns about a child’s physical and emotional welfare.

How?

Intervention

MST-CAN therapists help families identify strengths within the family system to help them manage the multiple risks that are contributing to the maltreating behaviours.

What?

Short-term

Maltreating parent behaviours stop

Child safety and stability in the home increases

Child wellbeing improves.

Medium-term

Reduced child maltreatment risk and recidivism

Reduced need for out-of-home placement

Reduced risk of child behavioural problems and other adverse child outcomes.

Long-term

Increased wellbeing throughout childhood

Improved life chances in adulthood.

Who is eligible?

Families who have recently been reported to Child Protection Services for physically abusing and/or neglecting a child between the ages of 6 and 17.

How is it delivered?

  • MST-CAN is delivered by a therapist individually to families in their homes.
  • Therapists are available 24/7 to the family and carry a caseload of three to four families at a time.
  • Therapy sessions typically last between 50 minutes and two hours.
  • The frequency of the sessions vary, depending on the needs of the family and the stage of the treatment, typically ranging from three days a week to daily.
  • Therapists work with individual families for an average of six to nine months.

What happens during the intervention?

The MST-CAN therapist works closely with his or her MST-CAN expert, supervisor, and family to find a good ‘fit’ between the family’s issues and tailored strategies. This includes identifying barriers to the success of the intervention (e.g. parental substance misuse or mental health problems) and developing methods for removing these barriers.

A key aim of the intervention is to help families assume greater responsibility for their behaviours and actively work to resolve serious family issues.

Who can deliver it?

MST-CAN therapists typically have a master’s qualification or higher in social work or clinical psychology.

What are the training requirements?

Practitioners have 104 total hours of intervention training. Booster training of practitioners is recommended.

How are the practitioners supervised?

  • It is recommended that practitioners are supervised by one host-agency supervisors with 120 hours of MST-CAN training.
  • It is recommended that practitioners are supervised by one of the intervention developer supervisors.

What are the systems for maintaining fidelity?

Intervention fidelity is maintained through the following processes:

  • Training manual
  • Other printed material
  • Other online material
  • Video or DVD training
  • Face-to-face training
  • Fidelity monitoring.

Is there a licensing requirement?

Yes

The most rigorous evidence for MST-CAN comes from a single RCT conducted in the United States, consistent with Foundations’ Level 3 evidence strength criteria. This study observed statistically significant improvements in children’s placement stability, the need for out-of-home placements, mental health, behaviour, and child maltreatment risk.
