Our Story
The Youth Untroubled team initially developed the ISTAC model (also known as Systemic Integrative Treatment) in 2017, whilst working at the Brandon Centre, London. Following extensive experience facilitating Multi-systemic Therapy® (MST) and various other clinical models and approaches to addressing complex childhood and family issues, ISTAC was developed in accordance with NICE guidelines to better meet the needs of children and families with complex and multiple problems and ultimately reduce out-of-home placements for children deemed beyond parental control. The model has been commissioned by several local authorities and mental health trusts across London, and nationally by F-CAMHS, and has been evaluated in a study by the Youth Endowment Fund.
In 2022, the Youth Untroubled founders decided the time had come to expand provision of the model outside of London - and Youth Untroubled Ltd was born. We also started adapting the original model so that other children, young people and young adults with differing complex needs could benefit from our intensive, goal-orientated, community-based, multi-systems approach to assessing, treating and overcoming problems.
We have since devised various adaptations of the model, including brief interventions such as 1:1 parenting workshops and consultations. The Youth Untroubled team are currently providing ISTAC across the South of England, London and the Midlands, and piloting ISTAC Schools and Colleges (ISTAC SAC) in Sussex, as well as brief parenting support services and interventions, and specialist consultation and training for other professionals, nationally.
