Implementation strategy
The implementation strategy covered the five domains of the Knowledge-into-Action Process Framework [The implementation phase for each partner organisation began with a two-day foundation-level training course to prepare participating staff to deliver the intervention. Following this, staff were to begin offering the intervention, supported by monthly group supervision sessions with the external facilitator. Intervention delivery was to continue for 12 months as part of the project. Advanced-level training was to be made available for practitioners who gained sufficient experience at foundation level. The intention was that advanced-level training would equip at least some staff in each organisation to support others in delivering the intervention, allowing for a gradual withdrawal of the external facilitator and promoting sustainability. A train-the-trainer course was also envisaged. The external facilitator, together with another member of the project team, conducted a formal mid-way meeting with steering group members to review progress, problem-solve regarding any barriers encountered, and explore and plan for future sustainability. We aimed to examine sustainability by following the first wave organisations for a further 12 months, and the second wave organisations for a further six months, after the end of the implementation period.
