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. 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 Cancerología 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. 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, < 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. 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.
患者尊严量表（PDI）是一种可靠的筛查工具，可用于评估各种影响终末期患者尊严的问题（身体、存在和社会方面）。PDI 已被翻译成多种语言，并在不同环境中得到验证。因此，在墨西哥的癌症患者中验证该工具以评估该人群的尊严非常重要。本研究的目的是翻译和验证墨西哥癌症患者的 PDIMx 西班牙语版本。这是一项横断面研究，纳入了 2018 年 9 月至 2019 年 8 月在墨西哥城国家癌症研究所的癌症患者，包括接受和未接受姑息治疗的患者。通过翻译和回译获得 PDIMx 仪器的墨西哥版本。患者完成 PDIMx、医院焦虑和抑郁量表（HADS）以及功能量表（东部合作肿瘤学组 [ECOG] 和卡诺夫斯基）。通过确定内部一致性、探索性和验证性因子分析（CFA）以及与 HADS 的同时效度来评估心理测量特性。我们纳入了 290 名癌症患者（145 名接受姑息治疗，145 名未接受姑息治疗）。PDIMx 的 Cronbach's alpha 为 0.95。与 HADS 呈显著相关性（rs=0.757， <0.0001）。因子分析显示四个因子，可解释模型的 64.7%。CFA 呈现出适当的指标，表明结构调整，表明模型平衡且简约。PDIMx 在癌症患者中具有良好的心理测量特性。我们建议在临床护理和研究中使用 PDIMx。该研究得到了机构审查委员会和伦理委员会的批准，编号分别为（016/063/CPI）和（CEI/1115/16）。
