Development of MST in Ireland
How MST Was Developed in Ireland
Multisystemic Therapy (MST) was introduced in Ireland through MST UK & Ireland, establishing a structured, evidence‑based approach for working with young people presenting high‑risk and challenging behaviours. The robust international evidence supporting MST—its impact on reducing out‑of‑home placements, improving emotional wellbeing, and strengthening social functioning—made it an attractive option for national policymakers seeking effective alternatives to detention.
MST and the Development of the Bail Supervision Scheme (BSS)
Ireland’s youth justice strategy emphasises detention as a last resort, prioritising community‑based supports that help young people remain safely at home, stay engaged in education, and maintain prosocial connections. In line with these principles, the Bail Supervision Scheme (BSS) was created to offer a therapeutic alternative to remand, supporting young people to comply with bail conditions while addressing the underlying drivers of offending.
Extern delivers the BSS using MST as its central intervention model, reflecting a strong alignment between the goals of MST and the needs of youth justice.
Why MST Fits the BSS Framework
MST’s principles—family empowerment, system‑focused assessment, intensive engagement, and targeted behavioural change—translate seamlessly into a judicial context. Within the BSS, MST operates as the key mechanism that supports young people, strengthens families, and increases court compliance.
How MST is Integrated into the Bail Supervision Scheme
The BSS incorporates core MST features to deliver meaningful and sustained change:
• Intensive, home‑ and community‑based therapy
Therapists work directly with young people and caregivers in their own environments, typically offering 2–3 in‑person sessions per week, alongside 24/7 crisis support.
• Small caseloads for high‑quality intervention
Each therapist works with only 4–6 families at a time, enabling a highly individualised and evidence‑driven approach.
• Focus on compliance with bail conditions
MST empowers caregivers to manage challenging behaviour, while helping young people attend court, remain in education or training, and engage positively in their communities.
• High‑intensity behavioural change
Therapists target the root causes of behaviour—peer influences, family conflict, disengagement from school, substance use—supporting young people to achieve sustainable improvements that extend beyond the bail period.
Expansion of MST Within Youth Justice in Ireland
Following strong evaluation outcomes, the BSS—delivered with MST at its core—expanded from its initial Dublin base to Cork and Limerick. Supported by Government commitment and the Research Evidence into Policy, Programmes and Practice (REPPP) evaluation, the scheme now operates across all three Children Court jurisdictions.
Through this expansion, MST has become embedded as the default therapeutic model for Ireland’s bail‑related youth justice interventions.
National Impact of MST Through the BSS
By integrating MST within the BSS framework, Ireland has achieved significant youth justice benefits:
• Reduced reliance on detention
MST stabilises behaviour and strengthens family functioning, helping prevent unnecessary remand placements and supporting the Children Act 2001 principle that detention should be used only as a last resort.
• Improved compliance with bail
Safety planning, ongoing monitoring, and caregiver empowerment support young people to meet court‑imposed requirements.
• Holistic and lasting behavioural change
By addressing systemic factors—peer groups, family dynamics, education, and substance use—MST promotes improvements that continue beyond the bail period.
• Community and economic benefits
Evaluation findings show reductions in Garda callouts, lower community risk, and increased educational and employment engagement, reflecting MST’s well‑documented wider system benefits.
Conclusion
The development of MST in Ireland is closely intertwined with the evolution of the Bail Supervision Scheme. Together, they represent a national commitment to a family‑centred, evidence‑based alternative to detention. MST provides the therapeutic structure that enables the BSS to deliver safer communities, reduced offending, stronger families, and effective support for young people—offering courts a trusted, research‑backed alternative to remand.
