Despite widespread interest in ambiguity tolerance and other information-related individual differences, existing measures of ambiguity tolerance are conceptually disparate and are often psychometrically weak. This paper presents evidence of reliability and validity for a 13-item measure of ambiguity tolerance (MSTAT-II) based on a definition of ambiguity tolerance as an orientation, ranging from aversion to attraction, toward stimuli that are complex, unfamiliar, and insoluble. The MSTAT-II addresses each basic type of ambiguous stimulus, contains fewer items than many other scales, and reduces references to specific contexts and objects not directly related to ambiguity. Data from three studies using diverse samples and measures, including other popular ambiguity tolerance scales, were examined, and the results suggest the MSTAT-II may improve upon other paper-and-pencil measures of ambiguity tolerance.
尽管人们对模糊容忍度及其他与信息相关的个体差异普遍感兴趣，但现有的模糊容忍度测量方法在概念上各不相同，而且在心理测量方面往往存在缺陷。本文基于将模糊容忍度定义为一种对复杂、陌生和无法解决的刺激的态度（从厌恶到吸引），给出了一个13项模糊容忍度量表（MSTAT-II）的信效度证据。MSTAT-II针对每种基本类型的模糊刺激，项目数量比许多其他量表更少，并且减少了对与模糊性无直接关系的特定情境和对象的提及。研究人员对三项使用不同样本和测量方法（包括其他常用的模糊容忍度量表）的研究数据进行了检验，结果表明MSTAT-II可能优于其他纸笔形式的模糊容忍度测量方法。
