背景资料：项目银行的建设和评价，以衡量一维结构的健康相关的生活质量（HRQOL）是一个基本目标的病人报告的结果测量信息系统（PROMIS）project.Objectives：项目银行将被用来作为基础，开发短形式的工具，使计算机自适应测试。PROMIS指导委员会选择了5个HRQOL领域作为初始重点：身体功能、疲劳、疼痛、情绪困扰和社会角色参与。本报告概述了PROMIS项目分析中使用的方法以及拟议的项目库校准。分析包括数据质量评价（例如，逻辑和范围检查，项目内响应分布的扩展），描述性统计（例如，频率、平均值）、项目反应理论模型假设（单维性，局部独立性，单调性），模型拟合，差异项目功能，以及银行项目校准。并对今后HRQOL测评中试题库的评价提出了建议。
Background: The construction and evaluation of item banks to measure unidimensional constructs of health-related quality of life (HRQOL) is a fundamental objective of the Patient-Reported Outcomes Measurement Information System (PROMIS) project.Objectives: Item banks will be used as the foundation for developing short-form instruments and enabling computerized adaptive testing. The PROMIS Steering Committee selected 5 HRQOL domains for initial focus: physical functioning, fatigue, pain, emotional distress, and social role participation. This report provides an overview of the methods used in the PROMIS item analyses and proposed calibration of item banks.Analyses: Analyses include evaluation of data quality (eg, logic and range checking, spread of response distribution within an item), descriptive statistics (eg, frequencies, means), item response theory model assumptions (unidimensionality, local independence, monotonicity), model fit, differential item functioning, and item calibration for banking.Recommendations: Summarized are key analytic issues; recommendations are provided for future evaluations of item banks in HRQOL assessment.
