The current study used confirmatory factor analysis to compare fit of the two-factor and bifactor models of the original and two short versions of the Intolerance of Uncertainty Scale (IUS) among a large sample of Chinese-speaking adults. The current sample consisted of 696 college or university students and 706 adults who were not currently in school. In order to examine the IUS' psychometric properties and validity, all participants completed the full-length IUS (n = 1402) and Penn State Worry Questionnaire (PSWQ; n = 1402), while some completed the neuroticism subscale of the Revised Eysenck Personality Questionnaire Short Scale for Chinese (EPQ-N; n = 1026), Beck Anxiety Inventory (BAI; n = 1026), Generalized Anxiety Disorder Scale-7 (GAD-7; n = 1026), and Beck Depression Inventory (BDI; n = 838). All measures were in Chinese and were delivered via online survey methods.
