The Intolerance of Uncertainty Scale (IUS) assesses emotional, cognitive, and behavioral reactions to ambiguous situations, implications of being uncertain, and attempts to control the future.
ITEM CODING
The IUS has 27 items- none reversed scored.
The IUS may be used as a unifactorial or a bifactorial assessment tool.
SCALES
To score the IUS as a unifactorial tool, add up the responses for each of the items.
As a bifactorial tool, the IUS is used to assess the following two factors:
Factor 1: Uncertainty has negative behavioural and self-referent implications
Factor 2: Uncertainty is unfair and spoils everything
To score Factor 1, add up the responses for items 1, 2, 3, 9, 12, 13, 14, 15, 16, 17, 20, 22, 23, 24, and 25
To score Factor 2, add up the responses for items 4, 5, 6, 7, 8, 10, 11, 18, 19, 21, 26, and 27
