Attitude Toward Ambiguity

Abstract

Two studies were conducted to examine the factor structure of attitude toward ambiguity, a broad personality construct that refers to personal reactions to perceived ambiguous stimuli in a variety of context and situations. Using samples from two countries, Study 1 mapped the hierarchical structure of 133 items from seven tolerance–intolerance of ambiguity scales ( N = 360, Italy; N = 306, United States). Three major factors—Discomfort with Ambiguity, Moral Absolutism/Splitting, and Need for Complexity and Novelty—were recovered in each country with high replicability coefficients across samples. In Study 2 ( N = 405, Italian community sample; N =366, English native speakers sample), we carried out a confirmatory analysis on selected factor markers. A bifactor model had an acceptable fit for each sample and reached the construct-level invariance for general and group factors. Convergent validity with related traits was assessed in both studies. We conclude that attitude toward ambiguity can be best represented a multidimensional construct involving affective (Discomfort with Ambiguity), cognitive (Moral Absolutism/Splitting), and epistemic (Need for Complexity and Novelty) components.
