Constructs of the Consolidated Framework for Implementation Research

Construct	How the construct relates to the DURE trial
Characteristics of the intervention—core components and adaptable components	Intervention characteristics (adaptability complexity, relative advantage) can influence whether the intervention is adopted
Inner setting—structural, political, and cultural context that directly affects the implementation	The context of the DSGs and the eye health system in Kirinyaga can influence how participants experience the intervention
Outer setting—broader economic, political and social context	Broader political, economic, health policies, priorities, resources, incentives, and governance may impact trial activities
Characteristics of individuals—people responsible for delivering the intervention (peer supporters)	Training, knowledge, perceptions, motivation, and leadership of peer supporters can influence extent of implementation of the intervention
Implementation process—the activities involved in planning, engaging, execution, and evaluation of implementation process	The involvement of stakeholders in the planning, execution, and evaluation of progress of the trial may influence the acceptability of delivery and reception of the intervention
