Facilitators
Six non-specialist male and female facilitators with past experience delivering psychosocial activities in their community delivered the EASE intervention, with two facilitators per intervention group. They received nine days of training in basic counselling skills, delivery of EASE, group facilitation, self-care, and organisational trainings, including child safeguarding, suicide risk management and security briefings. Additionally, they completed a supervised practice cycle of EASE intervention (comprised of individuals without high levels of distress) and underwent an assessment of competencies to be eligible to implement the intervention. Weekly group supervision was provided by local trainers who received a training-of-trainers and had previously conducted their own EASE intervention groups. They also received training in supervisory techniques, in order to ensure protocol adherence. Trainers themselves received regular supervision (from AM, FB, or MA), to ensure treatment adherence and provide support.ETAU facilitators were recruited using the same criteria and process as EASE facilitators. They received three days of training in delivering the scripted session, basic counselling and communication skills, and self-care. At the end of training a role-play competency assessment was conducted. Given the single session nature of ETAU, facilitators received one group supervision session mid-way through implementation of the sessions, and a group debrief and feedback session once all intervention sessions were completed.
