Clinical and research implications
Training guides and detailed procedures were developed for all study staff. The ability of the OWG leader to modify as appropriate for safety concerns was also built in. These components may make the interventions sustainable for future community implementation. However, it would be important to meet with community groups to review and revise the documents for language clarity and level of expertise to be useful for community implementation. Incorporating additional behaviour change and motivational strategies into the intervention could help with community implementation and attendance in OWG interventions. Aspects of our procedures which could be applied to future process evaluations were: identifying the evaluation process a priori at the time of the protocol publication and incorporating the aspects of self-report and device-based assessment in the process evaluation.
