Discussion
Findings from this quantitative process evaluation of the GO-OUT trial demonstrated that the workshop was successfully implemented at multiple sites as per protocol and participants were engaged in the workshop. The provision of a high percentage of the WR to participants provides evidence of implementation fidelity of the WR intervention. The five components of the OWG sessions, as outlined in the protocol, were successfully implemented with participants in the study. However, average attendance was not high. Evaluations with accelerometry and GPS during week 3 and 9 OWG sessions suggest that participants who attended were engaged and active during the OWG. This process evaluation demonstrates feasibility for community implementation and can help to explain the main study findings.
