Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy of .85 and a significant result on Bartlett’s test of Sphericity χ2= 5052,53 (p< .001, df= 66). Results confirmatory factor analyses demonstrated that 12 items yielded two factor as original form and that the two-dimensional model was well fit (χ²= 147.20, df= 48, RMSEA=.073, CFI=.95, IFI=.95, GFI=.94, and SRMR=.046). Factor loadings ranged from .55 to .87. In the concurrent validity significant relationships were found between the Intolerance of Uncertainty Scale (IUS-12) and Coping Flexibility Scale, Educational Stress Scale (r= -.43, .41 respectively). Test-retest reliability coefficient was .74.

Cronbach alpha internal consistency coefficient was found as .88 for overall scale, .84 for prospective anxiety subscale and .77 for inhibitory anxiety subscale.
