概要	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 EBPAS-36 is a 36-item self-report questionnaire that assesses clinicians' and organizational leaders' attitudes toward adopting and implementing evidence-based practices (EBP). Developed by Aarons in 2005 and refined through multiple validation studies, it measures four core dimensions: perceived requirements to adopt EBP, the appeal and usefulness of EBP to individual practice, organizational openness to innovation, and perceived divergence between current practice and EBP requirements. The EBPAS is widely used in healthcare, mental health, child welfare, and substance abuse treatment settings to predict adoption readiness and guide implementation planning.
