ABSTRACT
In implementation process evaluation, the analysis of the temporal structure of processes is key for understanding the successive interactions between the flow of practitioners' actions and evolving workplace reactions and context. However, capturing the temporal structure of processes in data analysis is a methodological challenge, and available literature to overcome this challenge is scarce, especially for workplace ergonomic interventions. The aim of this paper was to perform an implementation process evaluation of an ergonomic train the trainer program taking into account the temporal structure of processes. We provided a method for qualitative data analysis based on a three-stage strategy: 1) producing the timeline of the implemented intervention, 2) identifying influential factors, 3) identifying determinant mechanisms (sequence of influential factors that intervened in the implementation process). This method allowed us to identify six determinant mechanisms positioned on the timeline of the intervention. Obstacles and levers were identified as a sequence of interrelated causes and consequences rather than isolated factors. We recommended success strategies for practitioners, while also shedding light on how organizations can better be prepared to undertake the intervention and their required actions to attain targeted intervention objectives.
