Sintesi	The Perceived Organizational Readiness for Assisting the System (PORAS) is a 19-item self-report measure developed by Helfrich and colleagues to assess organizational readiness to implement health information technology systems and other healthcare innovations. Grounded in Weiner's theory of organizational readiness for change, the PORAS measures four dimensions of readiness: Valence (perceived importance of the change to the organization), Motivation (organizational commitment and drive to implement), Resource Adequacy (availability of financial, human, and technical resources), and Change Efficacy (staff belief in organizational capability to successfully implement). While originally developed for health IT implementation, the PORAS framework and scale are applicable to broader healthcare innovations and evidence-based practice implementation.	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.
