Context 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. Objectives We 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. Methods In 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. Results Three 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. Conclusions The 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.

Abstract

Context 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. Objectives We 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. Methods In 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. Results Three 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. Conclusions The 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.
