CDI webinar series on methods for theory-based evaluation

Theory-based evaluations: Dealing with complex interventions and ‘small n’ evaluation scenarios

1 June 2021 13:00–14:00

This session will provide participants with an overview of how best to evaluate complex interventions and deal with ‘small n’ evaluation scenarios. We first rehearse the challenges of conducting evaluations in these contexts and then discuss qualitative and participatory approaches that partially respond to these so-called ‘small n methods’ as an alternative to experimental approaches to establishing causation. We explore the role that these evaluations can have for theory- testing, theory- building, and explaining outcomes.
