Pressure ulcer development is a known indicator of the quality of care. Negative attitudes towards the prevention of pressure ulcers can lead to preventive care with suboptimal quality. There is no valid and reliable instrument in Iran to assess clinicians' attitudes towards pressure ulcer prevention; therefore, this study aimed to examine the psychometric properties of the Persian version of the Attitude towards Pressure ulcer Prevention instrument (APuP) in Nurses.
In this cross-sectional study, 250 nurses were selected using a convenience sampling method. Face, content, and construct validity were examined using exploratory factor analysis (EFA). Internal consistency was assessed using the McDonald's omega (ω), and reliability was assessed using the test-retest method.
In the EFA, five factors of Competence, Responsibility, Perceived Consequences of Pressure Ulcers on Patients, Priority, and Confidence in the Effectiveness of Prevention were extracted that together explained 50.26% of the total variance. A McDonald's ω of 0.891 demonstrated the internal consistency of the total scale, and internal consistencies ranging from 0.70 to 0.86 were found for different dimensions of the instrument. In addition, an intraclass correlation coefficient (ICC) of 0.876 was found that indicated the reliability (stability) of the total scale (95% Confidence Interval [CI]: 0.736-0.963).
The Persian version of the Attitude towards Pressure ulcer Prevention instrument (APuP) has good validity and reliability in Iranian nurses and can be used in future clinical studies.
压疮的发展是护理质量的已知指标。对预防压疮的消极态度可能导致预防护理质量不佳。伊朗没有评估临床医生预防压疮态度的有效和可靠工具；因此，本研究旨在检验护士中文版预防压疮态度量表（APuP）的心理测量特性。
在这项横断面研究中，采用便利抽样法选择了 250 名护士。采用探索性因子分析（EFA）检验表面、内容和结构效度。使用 McDonald's omega（ω）评估内部一致性，使用重测法评估可靠性。
在 EFA 中，提取了五个因素，即能力、责任、对患者压疮后果的感知、优先级和预防效果的信心，这五个因素共同解释了总方差的 50.26%。总量表的 McDonald's ω 为 0.891，表明内部一致性良好，仪器不同维度的内部一致性在 0.70 至 0.86 之间。此外，还发现组内相关系数（ICC）为 0.876，表明总量表的可靠性（稳定性）良好（95%置信区间[CI]：0.736-0.963）。
伊朗护士中文版预防压疮态度量表（APuP）具有良好的效度和信度，可用于未来的临床研究。
