Pressure injuries (PIs) are a major health problem with severe implications for patients. Professionals who care for people at risk should have high knowledge about PIs prevention. The actual knowledge can be measured using different tools, but we have found no questionnaire to measure the knowledge on PIs prevention developed and validated for Spanish-speaking countries. The aim of this study was to develop a questionnaire in Spanish to measure the knowledge about PIs prevention based on current international guidelines. Content validity was evaluated by 12 experts in wound care. A convenience sample of 438 nursing professionals from Spain participated to evaluate the questionnaire using item analysis, Rasch model, and known-groups validity. The PI Prevention Knowledge (PIPK) questionnaire shows good discrimination and difficulty indices. The 31-item PIPK shows good fit and reliability of 0.98 for items and 0.72 for people; also, it has enough evidence for construct validity. Because the questionnaire has been developed based on the recommendations from international guidelines, the English version of this questionnaire could be used in further studies to test its psychometric properties.
压力性损伤（PI）是一个严重影响患者的主要健康问题。护理高危人群的专业人员应该具备关于 PI 预防的高度知识。实际知识可以使用不同的工具来衡量，但我们还没有发现为西班牙语国家开发和验证的用于衡量 PI 预防知识的问卷。本研究旨在根据当前的国际指南开发一种西班牙语问卷来衡量 PI 预防知识。内容有效性由 12 名伤口护理专家进行评估。来自西班牙的 438 名护理专业人员的便利样本参与了使用项目分析、Rasch 模型和已知组有效性来评估问卷。PI 预防知识（PIPK）问卷显示出良好的区分度和难度指数。31 项的 PIPK 具有良好的拟合度和项目 0.98 的可靠性以及人员 0.72 的可靠性；此外，它还有足够的结构有效性证据。由于该问卷是根据国际指南的建议开发的，因此可以在进一步的研究中使用此问卷的英文版本来测试其心理测量特性。
