Process Evaluation


Randomised controlled trials (RCTs) are considered the most rigorous way to evaluate intervention effectiveness. However, it is not enough for an evaluation to report solely on effectiveness. Evaluations should also provide information on the planning, delivery, and uptake of the intervention, the causal pathways through which the intervention is expected to act, and the contextual factors affecting the implementation and outcomes of the intervention – the process that takes place.
