Eighty-one eligible young people from three English counties (27/county; Hertfordshire, Bedford, and Norfolk) were selected. This sample size was selected to enable 20 participants per arm to attend the intervention sessions (assuming 33% dropout) and allows for each of the 3 interventions to be completed at each of the 3 study sites, giving 9 groups in total. Each group needs to have 9 participants to ensure that at any given session at least 6 participants are present (allowing for 33% no show/drop out). As this is a feasibility study it is not powered to detect a difference in clinical outcomes between the two intervention arms and the social control arm. Therefore, no power calculation has been performed. A sample size of 81 participants will allow us to gain experience in running each intervention at each site. It will also allow us to estimate the outcome completion rate to within ± 6% assuming a completion rate of 80% using an 80% confidence interval.
