Plain English Summary
Background and study aims
Youth antisocial behaviour is a common and serious problem with costly consequences to young people themselves, their families, and society in general. Antisocial behaviour is associated with higher rates of criminal behaviour, unstable relationships, unemployment, and mental health problems. Multisystemic Therapy (MST) is an intensive family and home-based intervention for young people with serious antisocial behaviour. Although the programme has had some positive outcomes in the U.S., its effectiveness has not yet been assessed in the UK. This study is made up of two parts. The purpose of the first part (START I) is to assess whether Multisystemic Therapy in the UK is more likely to reduce out of home placement compared to management as usual (MAU; i.e., whichever services they would have received in the absence of MST). The purpose of the second part (START II) is to assess whether MST is more likely to reduce criminal convictions compared to MAU.
Who can participate?
Young people who meet three of seven risk indicators, such as history of offending, poor school attendance, and previous episodes of being looked-after.
What does the study involve?
Families which are considered eligible for the study are invited to take part in the research. Each family is randomly allocated to a treatment programme: either MST, or MAU. Research assistants visit the family home with a questionnaire pack at baseline, 12, and 18 months, and (START I), and 24, 36 and 48 months (START II). The questionnaires take about 1-2 hours to complete. Families are also invited to take part in optional qualitative interviews, in which they are asked about their experiences with MST, and about their lives and well-being after taking part in the programme.
What are the possible benefits and risks of participating?
Families taking part in the study are reimbursed £25 per visit. No other direct benefits or risks are anticipated.
Where is the study run from?
The study is run by University College London and takes place in nine NHS sites providing MST services in England (UK)
When is the study starting and how long is it expected to run for?
January 2009 to September 2017
Who is funding the study?
Department for Children, Schools and Families in conjunction with the Department of Health (UK)

START (Systemic Therapy for At Risk Teens): a national randomised controlled trial to evaluate multisystemic therapy for young people at risk of out of home placement as a result of antisocial behaviour in the UK context
The aim of this study is to carry out a pragmatic trial that will inform policy makers, commissioners of services and professionals about the potential of Multisystemic Therapy (MST) in a UK context, investigating whether the provision of MST could reduce the incidence of out of home placements for young people at risk of being removed from their homes because of antisocial behaviour, mental health problems, educational problems or unmet need.
The primary outcome of the study is to determine whether criminal conviction is reduced at 5-year follow-up in the MST arm compared to MAU.

Mental health problems and antisocial behaviour in adolescents
MST is offered to families for a period of three to six months, depending on individual family needs. Treatments offered in the MAU arm are widely varied, depending on resources available within the local authority and individual family needs.
Once a referral has been accepted into the study, the research assistant visits the family to confirm participation and complete consent forms. An independent statistician then manages the randomisation and the MST team administrator contacts the Trial Coordinator to find out the results of the randomisation. If the family has been allocated to MAU, the MST supervisor alerts the multi-agency panel for treatment allocation.
MST: Multi-systemic therapy is an integrative, manualised, licensed programme with a substantial evidence base for engaging young people exhibiting anti-social behaviour and their families. Adolescents with severe conduct problems (violence, drug abuse, school expulsion) are treated over a period of 3-6 months with a community-based multi-component treatment programme focused on the family but also engaging schools, neighbourhoods and community resources and administered by specifically trained professionals with relatively low caseloads. Adolescents and their families receive a minimum of 3 and a maximum of 6 months of input from the MST team; it is expected that some families will require briefer periods of treatment or may prematurely terminate treatment unilaterally. MST is delivered by a team of at least 3 specially trained clinicians under the supervision of an MST supervisor, with weekly one hour conference calls for consultation with an MST services staff member. In addition, MST therapists have the support of local consultation from mental health professionals with post-graduate qualifications in disciplines such as social work, psychology or counselling.
MAU: Management As Usual is the standard care offered to adolescents and their families who meet eligibility criteria for the trial. This treatment is likely to be diverse and may involve no therapeutic intervention or individual or family orientated work. It is likely to be delivered by a wide range of practitioners with quite different theoretical orientations. The average duration of these interventions is also likely to vary. It is expected that practitioners will be working in line with best practice as specified in relevant SCIE and NICE guidance. MAU interventions are carefully monitored using a service use schedule designed specifically for the trial that will record contact with all services (health, social, YOT, education, voluntary sector etc), including number of contacts (and possibly average duration of contacts). As this is a pragmatic trial involving a number of collaborating services even within each site, it is not possible to specify in advance what management as usual will be.
Families are followed up to 24 months in START I.
The study involves the 684 families (young people and parents/carers) recruited into the START I trial. All participants were initially sent an opt-out letter, giving them information on how they could opt-out of being contacted by the research team about START II. If the family does not opt out, the research team contacts the family to discuss continued participation in the trial. If the family agrees to take part, they are given an updated information sheet, and asked to sign an updated consent form, explaining the extension of the study to 60 months. Participants are then invited to take part in yearly follow-up assessments at 24, 36, and 48 months post randomisation. At each follow-up point, the family is contacted by the research assistant (RA) who schedules a time to visit the family in person. Both the young person and the parent separately complete the questionnaire pack with the assistance of the RA. The questionnaire pack takes approximately 2-3 hours to complete and includes assessments of emotional well-being, mental health, education and work adjustment, physical health, demographic data, antisocial behaviour (e.g., arrests, convictions), family cohesion and parenting. Parents and young people receive £12.50 each for taking part.
Primary outcome data (offending) continues to be collected up to 60 months post randomisation, unless the family does not give consent for this.
Additionally, all families are invited to take part in a qualitative component of the study, comprised of semi-structured interviews with young people and parents about their experiences with MST, their outcomes in terms of offending, emotional well-being, relationships with family and peers, and their outlook on the future. The interviews will be analysed for themes using Framework analysis.
