这篇论文是几篇论文中的第一篇，这些论文旨在演示如何将项目反应模型应用于行为科学，以增强研究人员和开发人员的概念和技术工具包，并更好地理解心理社会测量的心理测量学特性。这些论文都使用了行为改变联盟数据档案中的基准数据。本文首先介绍了项目反应模型，包括二分式和多分式两种模型。介绍和描述了应答者和项目定位、模型解释、标准误差和检验模型拟合度等概念。基于自我效能量表数据的样本分析被用来说明概念和技术。
This paper is the first of several papers designed to demonstrate how the application of item response models in the behavioral sciences can be used to enhance the conceptual and technical toolkit of researchers and developers and to understand better the psychometric properties of psychosocial measures. The papers all use baseline data from the Behavior Change Consortium data archive. This paper begins with an introduction to item response models, including both dichotomous and polytomous versions. The concepts of respondent and item location, model interpretation, standard errors and testing model fit are introduced and described. A sample analysis based on data from the self-efficacy scale is used to illustrate the concepts and techniques.
