Just to be certain: Confirming the factor structure of the Intolerance of Uncertainty Scale in patients with obsessive-compulsive disorder

Abstract

Intolerance of uncertainty (IU) is a cognitive construct in obsessive-compulsive disorder (OCD); yet no studies exist confirming the factor structure of the most widely used measure of IU, the intolerance of uncertainty scale (IUS), in OCD patients. Moreover, no studies have examined how scores on this measure relate to OCD symptom dimensions. Accordingly, the present study examined a 12-item two-factor revised version of the IUS (IUS-12) in 205 OCD patients. Confirmatory factor analysis verified the scale's two-factor structure. The measure also demonstrated high internal consistency and the IUS-12 was correlated moderately with another self-report measure of IU. Finally, theoretically consistent and specific relationships emerged between the IUS-12 and OCD symptom dimensions. These findings are discussed in terms of implications for the assessment and treatment of OCD, and specifically how elevated scores on the IUS-12 subscales may be utilized to identify subtleties in the presentation of OCD-related problems with IU.

  • The IUS-SF has satisfactory convergent validity with anxiety, worry, and depression, high internal consistency (α > 0.9), and a factor structure replicated in an OCD sample.

    “In the original scale development research, it was found to have satisfactory convergent validity with assessments of anxiety and worry, as well as depression.”
  • Intolerance of uncertainty has been linked to OCD, PTSD, panic disorder, and most other anxiety disorders.

    “intolerance of uncertainty has also been linked to OCD (Holaway, Heimberg, & Coles, 2006; Jacoby, Fabricant, Leonard, Riemann, & Abramowitz, 2013; Tolin, Abramowitz, Brigidi, & Foa, 2003), PTSD (Boelen, Reijntjes, & Smid, 2016; Oglesby, Boffa, Short, Raines, & Schmidt, 2016), panic disorder (Carleton et al., 2014; Carleton, Fetzner, Hackl, & McEvoy, 2013), and most other anxiety disorders (see Car”

    From Enhancing Inhibitory Learning: The Utility of Variability in Exposure (2019) · cites this paper as Jacoby, Fabricant, Leonard, Riemann, & Abramowitz, 2013

  • There has been considerable support for a two-factor IUS-12 structure: a 7-item prospective IU scale and a 5-item inhibitory IU scale.

    “there has been considerable support for a two-factor IUS-12 structure: (1) a 7-item prospective IU scale related to action/approach-oriented strategies in order to increase certainty (e.g. seeking more information), and (2) a 5-item inhibitory IU associated with inaction/avoidance-oriented thoughts and behaviours (e.g. delayed decision-making) [251, 259, 264–271].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
