Psychometric Testing of the Filipino Translation of Patient Perceptions on Safety Culture in a Hospital Setting (PPSC-H) Scale [Title Slide]
Abstract
A reliable and valid tool that measures patient safety perception is essential in developing patient-centered safety initiatives, improving quality of care, and supporting sound organizational decision-making. The Patient Perception on Safety Culture in a Hospital Setting Scale (PPSC) is a newly developed instrument that assesses how hospitalized patients perceive safety culture (Valdez et al., 2023). This study aimed to determine the psychometric properties of the Tagalog translation of the PPSC.
This quantitative methodological research was conducted in three phases. Phase 1 involved the Tagalog translation of the tool by a professional linguist, followed by expert review to establish content validity. Phase 2 focused on validity testing, where the Tagalog PPSC and the Patient Measure of Safety (PMOS-10) were administered simultaneously to 989 participants to assess construct and concurrent validity. Phase 3 evaluated reliability through a seven-day test–retest procedure using the same instrument to determine its stability over time.
The tool achieved a CVR of 0.76, supporting strong content validity. Factor analysis identified four factors explaining 53.97% of the variance, providing evidence of construct validity. A moderate-to-strong correlation with the PMOS-10 (r = 0.642, p < 0.001) indicated good concurrent validity. Subscale Cronbach’s alpha values ranged from 0.74 to 0.88, demonstrating acceptable to good internal consistency across its four dimensions. Test–retest reliability showed moderate-to-good agreement between measurements (Individual ICC = 0.525, Average ICC = 0.689, p < 0.001), indicating that the Tagalog PPSC-H yields reasonably stable results over time.
Overall, the Tagalog version of the PPSC-H demonstrated good content validity, robust construct validity, acceptable internal consistency, strong concurrent validity, and moderate test–retest reliability. These findings support its psychometric soundness as a tool for assessing patients’ perceptions of safety culture in hospital settings. The scale shows potential as a culturally relevant instrument for integrating patient perspectives into safety assessments, enhancing engagement, and informing data-driven strategies for continuous quality and safety improvement. Further validation across other major Filipino dialects is recommended to broaden its applicability and ensure usability among diverse patient populations in the Philippines.

Description
This presentation highlights the translation and validation of the Tagalog PPSC-H, a tool that captures patients’ perceptions of hospital safety culture. Attendees will gain insights into its psychometric strengths and its value in enhancing patient engagement and informing quality and safety initiatives.
