Primary use / Purpose:
The Intolerance of Uncertainty Scale – Short Form (IUS-12) has a strong correlation with the original scale, rs = .94 to .96 (Carleton, Norton, et al., 2007; Khawaja & Yu, 2010), a continuous latent structure (Carleton, Weeks et al., 2012), and has been shown to have two factors (Carleton, Norton, et al., 2007; McEvoy & Mahoney, 2011), prospective IU (7 items; e.g., “I can’t stand being taken by surprise”) and inhibitory IU (5 items; e.g., “When it’s time to act, uncertainty paralyzes me”), both with identically high internal consistencies, α = .85 (Carleton, Norton, et al., 2007).
The IU construct has been found to be ubiquitous, with scores comparable across anxiety disorders and depression (Carleton, Mulvogue et al., 2012). The IUS-12 was selected to measure IU because it is comparable to, but briefer than, the longer original IUS (Khawaja & Yu, 2010) and the new symptom-focused Intolerance of Uncertainty Index (IUI; Carleton, Gosselin, & Asmundson, 2010; Gosselin et al., 2008).
Good convergent and discriminant validity, as well as internal consistency, have been demonstrated by the total score and both subscale scores (Carleton, Norton, et al., 2007; McEvoy & Mahoney, 2011).
Prospective Anxiety Subscale: sum of items 1,2,4,5,8,9,11
Inhibitory Anxiety Subscale: the sum of items 3,6,7,10,12
Total Score: the sum of all items
