Abstract
Objective: The objective of the current study was to assess the reliability and validity of Perceived Stress Scale 10 (PSS-10) among warfarin patients.
Methodology: A cross-sectional study was performed among warfarin patients using the PSS-10. Sociodemographic and patients reported clinical data were collected. Descriptive and inferential statistics were applied using the Statistical Package for Social Sciences (SPSS) version 24.0. A p-value < 0.05 was considered statistically significant.
Results: There were more female patients (n=238, 65.9%) than the male patients (n=123, 34.1%) in total of 361 studied patients. No major issues regarding internal consistency, factorial validity, convergent validity and floor and ceiling effect were observed.
Conclusion: The present study confirmed the reliability and validity of PSS-10 among warfarin patients.
