确定与健康相关的生活质量问题是照顾癌症患者时的优先事项。具体的问题领域，如疼痛，疲劳，情绪困扰，疾病和治疗相关的症状，以及身体功能，可以使用项目反应理论的应用程序进行常规评估。项目反应理论测量模型可以改善经典的方法，以健康相关的生活质量评估的优势，包括患者在不同的仪器，所需的精确度的灵活性，多个简短的形式，间隔测量和个人评估的能力（实时临床监测）使用计算机自适应测试的可用性比较。本文综述了肿瘤学中健康相关生活质量的模型以及项目反应理论对使用该模型进行评估的贡献。
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.
