A Trial of Multisystemic Therapy in UK a Statutory Therapeutic Intervention for Young Offenders
To evaluate whether Multisystemic Therapy (MST) is more effective in reducing youth offending and out-of-home placement in a large, ethnically diverse, urban U.K. sample than an equally comprehensive management protocol; to determine whether MST leads to broader improvements in youth sociality and in mediators believed to be responsible for change in MST.
Participants Are Male and Female Adolescents 13-16 Years at Risk for Continuing to Commit Criminal Offences.
Other: Multisystemic therapy
Other: YOT (usual services)
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Prevention
- Change in offending behavior based on police records of criminal offenses committed [ Time Frame: baseline and 6, 12, 18, 24, 30 and 36 months post randomization ] [ Designated as safety issue: No ]The number of records of offending behavior (count data) was obtained, and 6-month periods free of any offending behavior were also recorded (binary data). Records were obtained from the National Young Offender Information System (YOIS) database. YOIS records detail offence information, court appearances, criminal orders, police custody records, and arrest rates.
- self- and parent-rated symptoms of antisocial behavior, delinquency-linked cognitions, personality functioning, and parenting variables [ Time Frame: baseline and 6 months after randomization ] [ Designated as safety issue: No ]Antisocial behavior was assessed using the Self-Report of Youth Behavior (SRYB), a brief, valid measure of the prevalence and incidence in pre-adolescent and adolescent children of delinquent behavior such as vandalism, theft, burglary, and fraud; and the delinquency and aggression subscales of the Youth Self-Report (YSR) and the parent-completed Child Behavior Checklist (CBCL).
- Antisocial Beliefs and Attitudes Scale (ABAS) [ Time Frame: Baseline and 6 months after randomization ] [ Designated as safety issue: No ]
- Antisocial Process Screening Device (APSD) [ Time Frame: Baseline and 6 months after randomization ] [ Designated as safety issue: No ]
- Measure of youth's involvement with delinquent peers (IDP) [ Time Frame: Baseline and 6 months after randomization ] [ Designated as safety issue: No ]
- Measure of Positive Parenting and Disciplinary Practices, Parent Monitoring and Supervision [ Time Frame: Baseline and 6 months after randomization ] [ Designated as safety issue: No ]

Experimental: Multisystemic therapy
MST is a family- and community-based intervention that establishes close contact with families to understand and deal with the factors that cause the young person's antisocial behaviour. The intervention targets the individual's adjustment, family relationships, school functioning and peer group affiliations. Therapists help caretakers develop skills to intervene and operate changes in important domains such as young person's individual adjustment, their family relationships, school functioning, and peer group affiliations.
|Other: Multisystemic therapy|
Active Comparator: YOT (usual services)
YOT intervention consisted of services currently available to young offenders in accordance with the Youth Justice Board National Standards.These services included supporting the young person to re-engage with education, with substance misuse problems and anger management; training them in social problem-solving skills; and programs to decrease vehicle-crime, violent-offending and knife crime. The treatments were delivered by professional social workers, specialist therapists or probation officers.
