Abstract

Background

In Oncology, little is known about the dignity – related distress and the issues that influence the sense of dignity for patients. W validated the Patient Dignity Inventory (PDI) questionnaire in Italian patients on oncological active treatments.

Methods

After the translation procedures, the PDI was administered to 266 patients along with other questionnaires to assess the psychometric properties of the Italian version of PDI. Factor structure was tested by both explorative and confirmatory factor analyses. Concurrent validity was tested through convergent and divergent validity with validated questionnaires inquiring about physical and psychological symptoms, and religiosity. The test/retest reliability was assessed through the concordance coefficient of Linn (two weeks interval, 80 patients).

Results

The explorative analysis suggested one factor only loading highly on all the 25 items (>.45) and explaining the 48% of variance; confirmative analysis and Cronbach alpha (0.96) confirmed the adequacy of the one-factor model. In the 2 weeks test-retest study a concordance coefficient of 0.73 (95% C.I.:0.64; 0.83) was found. High correlations of problems with dignity were found with both physical and psychological symptoms (0.52 and 0.64 rho coefficient, respectively), and moderate inverse correlation with spiritual well being (-.40). The dignity construct, as measured by PDI; showed to be orthogonal to that of religiosity (-.02).

Conclusions

The Italian version of PDI is a valid and reliable tool to evaluate the dignity related-distress in out-patients with either solid and haematological cancers, on active oncological treatments, in non advanced stage of the disease.
