Strengths and limitations
Strengths of this quantitative process evaluation included the use of multiple measures to evaluate OWG participant engagement and implementation fidelity. Measures included both facilitator-reported measures and device-based measures of the walking achieved during two weeks of the intervention. A limitation of this process evaluation is that findings represent the unique circumstances of the participants (those with self-perceived walking difficulties), and may not be relevant in other contexts. Reasons for non-attendance of the workshop, OWG or non-receipt of the WR were not consistently recorded; future projects could revise procedures to make this aspect clearer. This study consisted of four sites with participants of different abilities, and site leaders made choices for comfort and safety of the participants, leading to some variations in the interventions by site.
