Intolerance of Uncertainty (IU) has been understood as a dispositional tendency to view the presence of negative events as unacceptable and threatening, regardless of the likelihood of those events occurring. The preference over the 12-item vs. 27-item of the IUS has been central to debate. The goals of the present study were to evaluate two competing models of measuring IU with model-fitting analyses and explore model invariance of gender (e.g. men vs. women). A sample of 980 individuals completed an online IUS survey. Results indicated that the two-factor short-form model provided better fit to the data compared to the full-length two-factor model proposed by. Results also indicated that the short-form IUS is gender invariant, suggesting acceptable use among men and women. These findings provide further support of a two-factor structure and suggest that the IUS is appropriate for men and women.
