Resumen:
Introduction: The Patient Dignity Inventory (PDI) is a reliable
screening instrument for a variety of problems (physical, existential,
and social) that affect the dignity of patients during their end of
life. The PDI has been translated into several different languages and
has been validated in different settings. As such, it is important to
validate the instrument in patients with cancer in Mexico to assess
dignity in this population. The aim of this study was to translate and
validate the Spanish version of the PDI in Mexican patients with cancer.
Methods: This is a cross-sectional study that included patients with
cancer, both those enrolled and not enrolled in palliative care, at the
Instituto Nacional de Cancerologia in Mexico City from September 2018 to
August 2019. A translation and back translation were performed to obtain
the Mexican version of the PDI (PDI-Mx) instrument. Patients completed
the PDI-Mx, the Hospital Anxiety and Depression Scale (HADS), and
functional scales (Eastern Cooperative Oncology Group [ECOG] and
Karnofsky). Psychometric properties were evaluated by determining
internal consistency, exploratory and confirmatory factor analysis
(CFA), and concurrent validity with the HADS.
Results: We included 290 participants with cancer (145 in palliative
care and 145 not enrolled in palliative care). The Cronbach's alpha of
the PDI-Mx was 0.95. There was a significant correlation with the HADS
(rs = 0.757, p < 0.0001). The factor analysis showed four factors that
explain 64.7% of the model. The CFA presented adequate indicators,
which show the adjustment of the structure that indicates a balanced and
parsimonious model.
Conclusions: The Mexican version of the PDI shows adequate psychometric
properties in patients with cancer. We suggest the use of PDI-Mx in
clinical care and research.
The study was approved by the Institutional Review Board and Ethics
Committee with numbers (016/063/CPI) and (CEI/1115/16) respectively.
