Safety Culture Through Patient Voice: Qualitative Validation of the Patients' Perceptions of Safety Culture Scale (PaPSC) in Cardiology and Cardiothoracic Surgery

Problem-centred interviews and the Think-Aloud method were used in this study to ensure active patient participation. Patients contributes by identifying areas where survey items needed further clarification or contextualization, thereby enhancing the validity and usability of the Patients' Perception of Safety Culture Scale (PaPSC). Their feedback also led to the refinements in the study design and tools, underscoring the importance of patient-centred approaches in healthcare safety research. Although patients were not directly involved in the study design, since the PaPSC scale items were predefined and derived from a prior critical review of existing instruments, their role in this validation study was crucial. The study aimed not to develop new items but to assess the applicability and clarity of an established instrument. The study empowered the patients to share their views openly in a supportive and respectful environment, offering valuable insights for improving safety culture assessment.
