Abstract

Intolerance of uncertainty (IU) is a characteristic predominantly associated with generalized anxiety disorder (GAD); however, emerging evidence indicates that IU may be a shared element of emotional disorders. Aims: This study aimed to examine IU across diagnostic categories, change in IU during transdiagnostic treatment, and the relationship between change in IU and treatment outcome. Method: Patients diagnosed with heterogeneous anxiety and depressive disorders received up to 18 weeks of a transdiagnostic cognitive-behavioral therapy intervention. Patient self-reported IU and self-report and clinician-rated symptom/functioning measures were administered at pretreatment and posttreatment. Results: When controlling for negative affectivity, IU correlated with measures of depressive symptoms and worry severity at pretreatment. Patients with GAD and panic disorder exhibited the highest pretreatment IU scores, yet IU scores did not differ significantly based on the presence or absence of a specific diagnosis. A significant decrease in IU was observed, and change in IU was related to reduced anxiety and depressive symptom levels at posttreatment across diagnostic categories. Discussion: Change in IU can be observed across problem areas in transdiagnostic treatment and such change is correlated with treatment outcome. © 2013 Wiley Periodicals, Inc.

    If intolerance of uncertainty is a shared factor, it should appear in emotional disorders beyond generalized anxiety disorder and obsessive-compulsive disorder, which may help explain comorbidity.

    “If this is the case for IU, then it should be present as a shared factor in not just GAD and OCD, but other emotional disorders as well, which may help to explain the high degree of comorbidity observed across different emotional disorders (Brown & Barlow, 2009).”

    Except for obsessive-compulsive disorder, intolerance of uncertainty has not been examined in the treatment of many anxiety and mood disorders or across multiple emotional disorders in a single treatment study.

    “However, with the exception of OCD (see Grayson, 2004, and Wilhelm & Steketee, 2006), IU has yetto be examined in the treatment of many anxiety and mood disorders, or across multiple emotional disorders in the context of a single treatment study.”

  • IU is strongly implicated in the etiology of generalized anxiety disorder and is a transdiagnostic risk and maintenance factor across mental health concerns and an intervention target.

    “IU is strongly implicated in the etiology of generalized anxiety disorder (GAD; Dugas et al., 1998), but more recently has been included in transdiagnostic models as a central risk and maintenance factor across mental health concerns and an important transdiagnostic intervention target (Boswell et al., 2013; Carleton, 2016; Einstein, 2014; McEvoy & Mahoney, 2012) in COVID-19 (Freeston et al., 2020”

    From The Indirect Effect of Parental Intolerance of Uncertainty on Perinatal Mental Health via Mindfulness During COVID-19 (2021) · cites this paper as Boswell et al., 2013

    The Abstract Results and Discussion (page not provided) report that IU was associated with symptoms across diagnostic categories, decreased during transdiagnostic treatment, and may be a shared factor in emotional disorders. The paper does not establish IU as a central risk and maintenance factor across mental health concerns generally; its Discussion calls for further research on IU’s role in etiology and maintenance. The GAD-etiology clause is attributed to Dugas et al., not Boswell et al. (LLM, conf=0.86)

  • Individuals with higher intolerance of uncertainty and tendency to worry are more prone to anxiety.

    “That is particularly the case for individuals with higher IU and tendency to worry which, in the cognitive behavioral literature, represent some of the most important factors that make a person prone to anxiety (Carleton et al., 2007, 2012; Boswell et al., 2013).”

    From Intolerance of Uncertainty and Tendency to Worry as Mediators Between Trust in Institutions and Social Support and Fear of Coronavirus and Consequences of the Pandemic (2021) · cites this paper as Boswell et al., 2013

    The paper’s Discussion (page not available) associates intolerance of uncertainty with anxiety disorders and describes excessive worry as a cardinal feature of generalized anxiety disorder. It does not establish that higher intolerance of uncertainty and worry make individuals more prone to anxiety, or rank them among the most important factors that do so. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • In neurotypical individuals, a reduction in intolerance of uncertainty is associated with a reduction in anxiety and improvements in everyday functioning.

    “intervention studies with neurotypical individuals suggest that a reduction in IU is associated with a reduction in anxiety and improvements in everyday functioning (see, for example, [14]).”

    From Coping with Uncertainty in Everyday Situations (CUES©) to address intolerance of uncertainty in autistic children: Study protocol for an intervention feasibility trial (2019) · cites this paper as [14]

    The Results (Change in IU and Posttreatment Symptom Severity; page not indicated) associate greater reductions in IU with lower anxiety symptom severity. But the Method (Participants; page not indicated) describes patients diagnosed with anxiety disorders, not a neurotypical sample. Although the Abstract (Method) mentions functioning measures, the reported IU-change analysis addresses symptom severity, not improvements in everyday functioning. (LLM, conf=0.88)

  • Several prominent models posit a direct causal link between uncertainty and anxiety.

    “Several prominent models posit a direct causal link between uncertainty and anxiety [35-37].”

    From Impact of Media-Induced Uncertainty on Mental Health: Narrative-Based Perspective. (2025) · cites this paper as [36]

    The conceptual discussion describes uncertainty as producing distress or arousal in GAD, OCD, and panic disorder, and relates intolerance of uncertainty to a model of emotional disorders. It does not establish that several prominent models posit a direct causal link between uncertainty and anxiety; the Discussion instead calls for more direct testing of explanatory models. Page numbers are unavailable in our copy. (LLM, conf=0.82)

  • Psychological and neural mechanisms through which uncertainty-inducing stressors elicit negative mental states, particularly anxiety, and may lead to psychopathology have been extensively described in the literature.

    “Psychological and neural mechanisms through which uncertainty-inducing stressors elicit negative mental states, particularly anxiety, and may lead to psychopathology have been extensively described in the literature [31,35,36,57,119,120], and these models are broadly relevant in the present context.”

    From Impact of Media-Induced Uncertainty on Mental Health: Narrative-Based Perspective. (2025) · cites this paper as [36]

    The Discussion (page unavailable) describes psychological pathways linking uncertainty to distress, anxiety, panic attacks, and emotional disorders. It does not describe neural mechanisms, so the source supports only the psychological part of the cited claim. (LLM, conf=0.86)

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.
