Implementation Leadership Scale (ILS)

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.
