OBJECTIVE
to perform the psychometric validation of the Brazilian version of the Patient Dignity Inventory (PDI - Br) in patients with advanced diseases in palliative care.
METHOD
a methodological study to verify the psychometric properties of the Patient Dignity Inventory (PDI - Br) instrument, through validity and reliability tests.
RESULTS
the exploratory factor analysis showed a factorial solution with three factors, responsible for 40.9% of the explained variance, with adequate internal consistency for the Presence of Symptoms (α=0.859), Dependence (α=0.871), and Existential Suffering (α=0.759) domains. The test-retest was performed and indicated moderate to strong correlations. Convergent validity demonstrated a positive correlation between the Presence of Symptoms and the sadness (r=0.443) and anxiety (r=0.464) variables. Weak negative correlations were observed between the PDI - Br domains and functionality, spiritual well-being and quality of life.
CONCLUSION
composed of three domains and 25 items, the PDI - Br instrument presented satisfactory psychometric properties for its use in our environment, through the evidence of validity and reliability.
目的
在姑息治疗中对晚期疾病患者进行巴西版患者尊严量表（PDI-Br）的心理计量学验证。
方法
通过有效性和可靠性测试，对患者尊严量表（PDI-Br）工具进行心理计量学特性验证的方法研究。
结果
探索性因素分析显示，该量表具有三个因子的因素解决方案，负责解释方差的 40.9%，具有足够的内部一致性，用于存在症状（α=0.859）、依赖（α=0.871）和存在痛苦（α=0.759）领域。进行了测试-重测，表明具有中度到高度相关性。收敛有效性表明，存在症状与悲伤（r=0.443）和焦虑（r=0.464）变量之间存在正相关。PDI-Br 领域与功能、精神健康和生活质量之间存在弱负相关。
结论
由三个领域和 25 个项目组成的 PDI-Br 量表在我们的环境中具有令人满意的心理计量学特性，具有有效性和可靠性的证据。
