Construct Details

ConstructAdaptation and evolution
DefinitionFor the success of D&I, interventions often need to be adapted to fit the local context (i.e., needs and realities). Adaptation is defined as the degree to which an evidence-based intervention is changed or modified by a user during adoption and implementation to suit the needs of the setting or to improve the fit to local conditions. The need for adaptation and understanding of context has been called Type 3 evidence (i.e., the information needed to adapt and implement an evidence-based intervention in a particular setting or population). Ideally, adaptation will lead to at least equal intervention effects as is shown in the original efficacy or effectiveness trial. To reconcile the tension between fidelity and adaptation, the core components (or essential features) of an intervention (i.e., those responsible for its efficacy/effectiveness) must be identified and preserved during the adaptation process.
