The Perceived Stress Scale (PSS) measures general life stress and the Impact of Events Scale (IES) measures retrospective stress from a specific event; both have been validated across various audiences and settings . However, neither measure stress during an evolving public health crisis . The aim was to refine the PSS to measure stress during an event (e.g . COVID-19 pandemic) and examine its psychometric properties within a 4-year Hispanic-Serving Institution in the Bronx, NY . Three items from the IES were added to and one PSS item was removed from the PSS-10, creating a new PSS-12 . Cronbach's & #945; for the scale was 0.902 for faculty and 0.903 for students, indicating high internal consistency . Factor analyses also supported calculation of two subtotals similarly across groups . The PSS-12 is a valid instrument to measure perceived stress during a public health crisis, particularly among populations that already experience community health disparities.
