Sammanfattning	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 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.
