Item response theory (IRT) methodology allowed an in-depth examination of several issues that would be difficult to explore using traditional methodology. IRT models were estimated for 4 risky-choice items, answered by students under either a gain or loss frame. Results supported the typical framing finding of risk-aversion for gains and risk-seeking for losses but also suggested that a latent construct we label preference for risk was influential in predicting risky choice. Also, the Asian Disease item, most often used in framing research, was found to have anomalous statistical properties when compared to other framing items. Copyright 1998 Academic Press.
项目反应理论（IRT）方法允许深入研究几个使用传统方法难以探索的问题。针对4个风险选择项目估计了IRT模型，这些项目由处于收益或损失框架下的学生回答。结果支持了收益时风险规避和损失时风险寻求这一典型的框架效应发现，但也表明我们标记为风险偏好的一个潜在结构在预测风险选择方面具有影响力。此外，与其他框架项目相比，框架研究中最常使用的亚洲疾病项目被发现具有异常的统计特性。版权所有1998年学术出版社。
