Abstract
CONTEXT
The Patient Dignity Inventory (PDI) is an instrument to measure dignity distressing aspects at the end of life.

OBJECTIVES
The aims of the current study was the translation of the PDI in Greek language as well as to measure its psychometric aspects in a palliative care unit.

METHODS
A back-translation method was obtained at the Greek version. 120 advanced cancer patients completed the Greek version of the PDI, the Greek Hospital Anxiety and Depression Scale (Gr-HADS), The Greek Schedule of attitudes towards hastened death (SAHD-Gr) and the Greek SF-12 (Short Form Health Survey: SF-12).

RESULTS
Confirmatory Factor Analysis failed to fit to the original instrument’s structure and . EFA was conducted revealing 5 factors (‘Psychological Distress’, ‘Body Image and Role Identity’, ‘Self-Esteem’, ‘Physical Distress and Dependency’, ‘Social Support’). The psychometric analysis of the PDI-Gr demonstrated a good concurrent validity and the instrument discriminated well between subgroups of patients regarding age differences. Cronbach’s alphas were between 0.71-0.9 showing a good internal consistency.

CONCLUSION
The Greek version of the PDI showed good psychometric properties in advanced cancer patients supported the usefulness of the instrument assessing the sense of dignity distressing aspects of the terminally ill cancer patients.
