Colliding ideals - internal and external validity

MMC's recent study describes how researchers responsible for replicating interventions face colliding ideals when trying to protect the internal validity of an intervention while considering adaptations to ensure that the intervention fits into the context. Some emphasised direct replications as central in the knowledge accumulation process (stressing adherence). Others assumed that interventions generally need to be improved, giving room for adaptations and reflecting an incremental approach to knowledge accumulation. This has implications for design and reporting of intervention studies as well as for how findings across studies are synthesised.
