Abstract

Aim: To evaluate the psychometric properties and measurement quality of the Patient-Reported Outcomes Measurement Information System Parent Proxy (PROMIS PP) Mobility item bank (v1.0, 23 items) for children with Duchenne muscular dystrophy (DMD), through Rasch statistical analysis.

Method: De-identified PROMIS PP Mobility items were completed by the caregivers of male patients with DMD, aged 4 to 12 years, as part of standard clinical care at the Nationwide Children's Hospital clinic; data were mined retrospectively from electronic health records. Rasch analysis was used to assess the internal functioning of the measure and items.

Results: Overall, 151 observations were available for the Rasch analysis, equally split between patients aged 4 to 7 years and 8 to 12 years. After removing clinically irrelevant items and regrouping response options for specific items, the resulting 19-item measure demonstrated overall good fit to Rasch model expectations and the ability to discriminate between respondents with different mobility levels (Person Separation Index = 0.95, excellent reliability).

Interpretation: The customized PROMIS PP Mobility measure demonstrated good fit and may be a reliable option for mobility assessment in children with DMD. Rasch analysis can be used by other researchers to improve the sensitivity of patient-reported outcomes in their field of interest.

在杜氏肌营养不良症中应用PROMIS父母代理活动能力题库的心理测量学评价。

目的：通过Rasch统计分析，评价患者报告结果测量信息系统（PROMIS PP）活动能力信息库（v1.0，共23个项目）对杜氏肌营养不良症（DMD）儿童的心理测量特性和测量质量。方法：由4 - 12岁男性DMD患者的护理人员完成去识别的PROMIS PP移动项目，作为全国儿童医院诊所标准临床护理的一部分；数据回顾性地从电子健康记录中挖掘。Rasch分析用于评估测量和项目的内部功能。结果：总的来说，有151项观察结果可用于Rasch分析，平均分为4至7岁和8至12岁的患者。在去除临床不相关的项目并重新分组特定项目的回答选项后，得到的19个项目的测量结果表明，总体上很好地符合Rasch模型的期望，并且能够区分不同流动性水平的受访者（Person Separation Index = 0.95，可靠性极佳）。解释：定制的PROMIS PP活动测量显示出良好的适应性，可能是DMD儿童活动评估的可靠选择。Rasch分析可以被其他研究人员用于提高他们感兴趣的领域中患者报告结果的敏感性。
