Psychometric Properties of the Patient Dignity Inventory in a Longitudinal Cohort of Acute Respiratory Failure Survivors
Authors' conclusion
The PDI is a valid, reliable instrument for assessing dignity among ARF survivors longitudinally, demonstrating excellent internal consistency and generalizability, providing a foundation for designing and evaluating dignity-centered interventions addressing ARF survivors' evolving needs.
