Identifying health-related quality of life concerns is a priority when caring for people with cancer. Specific problem areas such as pain, fatigue, emotional distress, disease- and treatment-related symptoms, as well as physical functioning can be routinely assessed using applications that draw upon item response theory. Item response theory measurement models can improve on the classical approach to health-related quality of life assessment with advantages that include comparison of patients across diverse instruments, flexibility in degree of precision desired, availability of multiple short forms, interval measurement and capability for individual assessment (real-time clinical monitoring) using computerized adaptive testing. This review describes a model of health-related quality of life in oncology and the contribution of item response theory to assessment using that model.
当护理癌症患者时，确定与健康相关的生活质量问题是当务之急。可以使用基于项目反应理论的应用程序来常规评估特定的问题领域，例如疼痛、疲劳、情绪困扰、疾病和治疗相关症状以及身体功能。项目反应理论测量模型可以改进与健康相关的生活质量评估的经典方法，其优点包括在不同仪器之间比较患者、所需精度程度的灵活性、多种简短形式的可用性、区间测量以及使用计算机自适应测试进行个体评估（实时临床监测）的能力。本综述描述了肿瘤学中与健康相关的生活质量模型以及项目反应理论对该模型评估的贡献。
