Design
RECRUITMENT
This study was a feasibility trial, following the intended RCT design: a two-arm individually randomised group treatment trial, with a 1:1 allocation of participants to EASE or enhanced treatment as usual (ETAU). We assessed: recruitment, screening, attendance, and retention rates of participants; fidelity and competence of facilitator delivery of the intervention; the feasibility of randomization and blinding procedures and the likelihood of contamination between treatment and control groups; psychometric properties and trends in outcome measures on a range of adolescent and caregiver outcomes at pre-intervention (“baseline”; T0), post-intervention (“endline”; approximately 8 weeks post-randomisation; T1), and 3-month follow-up (approximately 20 weeks post-randomisation; T2). At T1 we conducted a qualitative process evaluation using semi-structured interviews and focus group discussions with participants and stakeholders. Study methods and results are reported following the CONSORT guidelines on the reporting of randomized feasibility and feasibility studies [
