Table 1 Five exposures that compose 3 study arms
From: Design of a dual randomized trial in a type 2 hybrid effectiveness—implementation study
5 types of study exposures | 3 study arms that are randomized |
|---|---|
Pa (active intervention program): an evidence-based intervention hypothesized to have a stronger effect on the health outcome compared to the control. It is used in both active and control arms in the test of implementation strategies Pc (control for active intervention program): an intervention that can be comparison treatment, an attention control or usual care/no new activity Sa (active implementation strategies): implementation strategies hypothesized to have a stronger effect on implementation outcomes compared to the control. It is used in active arm of test of implementation strategies Sc (control for active implementation strategies): implementation strategies hypothesized to have a measurable non-zero effect on the implementation outcome. It is used in control arm in test of implementation strategies Sx (implementation strategies used to administer control intervention program): the implementation strategies are designed to be consistent with the type of control intervention | SaPa: active arm in test of implementation strategies and intervention program ScPa: control arm in test of implementation strategies SxPc: control arm in test of intervention program |
