요약	Fidelity of Implementation refers to the degree to which an evidence-based practice or intervention is delivered as originally designed and intended. The Fidelity of Implementation Scale (or fidelity assessment framework) operationalizes this concept by specifying the core components of an intervention, defining each component precisely, and then assessing whether practitioners deliver each component when appropriate. Fidelity is distinct from adoption (whether staff use the innovation) and outcomes (whether the innovation produces the intended benefit). An innovation can be widely adopted but delivered with low fidelity (incorrectly or incompletely), often resulting in poor outcomes. Conversely, perfect fidelity without adaptation may fail in some contexts. Fidelity monitoring is essential in implementation science to understand whether implementation failures stem from ineffective interventions (true lack of efficacy) or ineffective delivery (low fidelity despite effective intervention). Fidelity assessment uses observation, checklist, and record review methods tailored to the intervention type.	The Implementation Leadership Scale (ILS) is a 12-item self-report measure that assesses unit-level leadership behaviors critical to successful implementation of evidence-based practices and innovations. Developed by Aarons, Ehrhart, and Farahnak in 2014, the ILS measures four dimensions of implementation leadership: proactive leadership, knowledgeable leadership, supportive leadership, and perseverant leadership. This brief, validated instrument is designed to capture frontline leaders' (managers, supervisors, unit heads) implementation-specific behaviors as perceived by clinical staff, and is widely used in healthcare implementation research to evaluate leadership effectiveness and predict implementation success.
