Background/Objective: Retirement homes and other gerontology services are frequently criticized due to their lack of flexibility and tailored attention, leading to homogeneous treatment which compromises patients’ control of their lives. This study aims to develop and validate the first Spanish instrument for healthcare professionals to assess the degree of person-centered attention delivered by senior care centers. Method: A total of 844 healthcare professionals (mean age = 39.94 years old; SD = 10.56) with a mean of 6.56 years (SD = 6.15) of work experience participated in the study. The psychometric properties of the questionnaire developed were analyzed using both classical test theory and item response theory models. Results: The internal structure was unidimensional with an explained variance of 55.23%. Reliability was outstanding: internal consistency (α = .96, ω = .96) and test-retest (r = .88; ICC = .93). The total score was significantly correlated with two similar questionnaires, with associated variance of 58.83% and 55.20% respectively. Conclusions: The new instrument allows healthcare professionals to assess the level of person-centered care provided by gerontology centers with excellent reliability and validity.

背景/目标：养老院和其他老年学服务经常因缺乏灵活性和针对性的关注而受到批评，导致治疗同质化，损害患者对自己生活的控制。本研究旨在开发和验证第一个西班牙工具，供医疗保健专业人员评估高级护理中心以人为本的关注程度。方法：共有 844 名医疗保健专业人员（平均年龄 = 39.94 岁； SD = 10.56）、平均工作经验 6.56 年（ SD = 6.15）参与了这项研究。使用经典测试理论和项目反应理论模型分析了所开发问卷的心理测量特性。结果：内部结构是一维的，解释方差为55.23%。可靠性非常出色：内部一致性（α = .96，ω = .96）和重测（ r = .88；ICC = .93）。总分与两份类似问卷显着相关，相关方差分别为58.83%和55.20%。结论：新工具使医疗保健专业人员能够评估老年学中心提供的以人为本的护理水平，具有出色的可靠性和有效性。
