The London Young People Study

The evaluation of the Your Choice programme

What is the London Young People Study?

To evaluate the potential effectiveness of Your Choice, the programme is being evaluated by a randomised controlled trial (RCT). This is a research method where teams are randomly picked to either deliver the new programme or to continue as they normally would. By comparing the two groups – the Your Choice teams and the Business As Usual teams – the Evaluators can determine the potential impact of Your Choice. The evaluation of the Your Choice programme is referred to as the London Young People Study. To find out more about RCTs watch the video discussion below:

Who is involved?

Project team 
The Your Choice programme has been developed by the London Innovation and Improvement Alliance (LIIA), supported by London’s Violence Reduction Unit (VRU). The LIIA team is responsible for the design, development and implementation of the programme whilst the VRU oversees financial aspects of the pan London programme and its evaluation.  

Evaluation team 
The evaluation is being carried out by the Institute for Fiscal Studies and the Anna Freud Centre. The project funders, the Youth Endowment Fund, place a strong emphasis on evaluating ways of working to provide evidence bases to change practice.

30 of London’s Boroughs  
Across London 30 Local Authorities (LA) are participating in the full-scale Efficacy trial to test out the Your Choice programme. Each of the participating LAs have at least one Your Choice team that is delivering the programme and one team that is operating as they normally would (Business As Usual/Control). Read more about the role of Your Choice practitioners here [hyperlink].  

To coordinate the evaluation locally each LA has one or more Single Points of Contact (SPOCs) who oversees the teams involved as well as those supporting the delivery of the Your Choice programme. Trainers provide the 5-day Your Choice training to practitioners and the Clinical leads supervise the Your Choice practitioners.
