The Patient Dignity Inventory (PDI) is a valid and reliable instrument to measure dignity, as a state of physical, mental, social, and spiritual well-being in palliative care patients and an essential dimension for a comprehensive patient-centered approach.ObjectivesWe examined the factor structure and correlation of the Italian version of the PDI (PDI-IT) with psychosocial variables among advanced and nonadvanced cancer outpatients in two Italian centers.MethodsIn a sample of 194 patients, principal component analysis, reliability analysis (Cronbach's coefficient alpha), and correlation analysis of the PDI-IT were performed. Concurrent validity was evaluated with respect to the Italian versions of Patient Health Questionnaire-9 (PHQ-9), as a measure of depression, the Mini-Mental Adjustment to Cancer-Hopelessness Scale, as a measure of dysfunctional coping, and the Demoralization Scale (DS-IT), as a measure of demoralization.ResultsThree factors were extracted by exploratory factor analysis, which accounted for 64.38% of the variance, namely existential distress (Cronbach's α = 0.95), psychological distress (Cronbach's α = 0.88), and physical distress (Cronbach's α = 0.81), with a Cronbach's α coefficient for the PDI-IT total score of 0.96. PDI-IT factors were significantly intercorrelated and shared between 42% and 53% of the variance. Higher scores on all the PDI-IT factors and PDI-IT total were found among patients who were clinically depressed (PHQ-9) and among those who were demoralized on the DS-IT. Significant correlations were also found between all PDI-IT and the DS-IT, PHQ-9, and the Mini-Mental Adjustment to Cancer-Hopelessness Scale.ConclusionsThe study confirmed that the PDI-IT is a valid instrument to be applied in oncology and measuring three factors, namely existential, psychological, and physical distress, as core dimensions of dignity, to be monitored and treated in clinical settings.
