Measurement of Ambiguity Tolerance

Presented definitions for the construct of ambiguity tolerance. The measure of ambiguity tolerance (MAT-50) had high internal reliability (r = .88) and high test-retest reliability (r = .86) over a 10-to-12 week period. A content analysis of the measure and a subjective analysis by 20 graduate students indicated adequate content validity. A multivariate comparison with two other ambiguity measures, two rigidity measures, and a short dogmatism measure provided strong evidence for criteria-related validity. Finally, four independent empirical studies showed good construct validity.
