Development and Validation of the Perioperative Care Process Adherence Scale

Sponsor: Volkan Gokmen

Summary

This study aims to develop a new measurement instrument, the Perioperative Care Process Adherence Scale (PBSUO), and to evaluate its psychometric properties. The scale is designed to measure the degree to which nurses working in operating rooms and surgical wards adhere to evidence-based perioperative care processes, including operating room safety, early postoperative monitoring and complication prevention, Enhanced Recovery After Surgery (ERAS) components, patient education and communication, and documentation continuity. The study is a multicenter methodological (scale development and psychometric validation) study conducted with nurses from operating rooms and surgical wards at three hospitals. Scale development proceeds in four phases: (1) generation of an initial item pool based on a literature review grounded in the Donabedian structure-process-outcome quality model, (2) content validity evaluation by a panel of 8-12 content experts, (3) cognitive pilot testing with 20-30 perioperative nurses to refine item wording and clarity, and (4) administration of the refined scale to a large multicenter sample (approximately 320-450 nurses) for exploratory and confirmatory factor analysis, evaluation of a second-order factor structure, reliability analysis, convergent and discriminant validity, measurement invariance between operating room and surgical ward nurses, and test-retest reliability over a two-week interval. The study does not involve any clinical intervention, physical procedure, or performance evaluation of participants; participation consists solely of completing self-report questionnaires, and results will not be shared with participants' employers or affect their employment status.
