可靠的变化指数已被用来评估健康相关的生活质量的个体变化的意义。我们估计了患者报告结局测量信息系统（PROMIS®）29项健康相关生活质量测量（PROMIS-29 v2.1）中两项测量（身体功能和情绪困扰）的可靠变化。使用两波的数据收集间隔3个月的纵向观察性研究的慢性腰痛和慢性颈部疼痛患者接受脊椎按摩治疗，和模拟，我们比较了可靠的变化估计从经典的测试理论固定标准误与项目反应理论的标准误从分级反应模型。我们发现，除非真正的PROMIS的身体功能和情绪困扰量表的变化是实质性的，经典的测试理论估计显着的个人变化要乐观得多的变化估计的基础上项目反应理论。在线版补充材料可通过10.1007/s11336-021-09774-1获得。
The reliable change index has been used to evaluate the significance of individual change in health-related quality of life. We estimate reliable change for two measures (physical function and emotional distress) in the Patient-Reported Outcomes Measurement Information System (PROMIS®) 29-item health-related quality of life measure (PROMIS-29 v2.1). Using two waves of data collected 3 months apart in a longitudinal observational study of chronic low back pain and chronic neck pain patients receiving chiropractic care, and simulations, we compare estimates of reliable change from classical test theory fixed standard errors with item response theory standard errors from the graded response model. We find that unless true change in the PROMIS physical function and emotional distress scales is substantial, classical test theory estimates of significant individual change are much more optimistic than estimates of change based on item response theory.
