Trait and situation-specific intolerance of uncertainty predict affective symptoms during the COVID-19 pandemic

BackgroundThe COVID-19 pandemic, a high-uncertainty situation, presents an ideal opportunity to examine how trait intolerance of uncertainty (IU) and situation-specific IU relate to each other and to mental health outcomes. The current longitudinal study examined the unique associations of trait and COVID-specific IU with general distress (anxiety and depression) and pandemic-specific concerns (pandemic stress and vaccine worry). MethodsA community sample of Florida adults (N = 2152) was surveyed online at three timepoints. They completed measures of trait IU at Wave 1 (April–May 2020) and COVID-specific IU at Wave 2 (May–June 2020). At Wave 3 (December–February 2021), they reported symptoms of depression, anxiety, pandemic stress, and vaccine worry. ResultsWe used structural equation modeling to test our overall model. Trait IU significantly predicted later COVID-specific IU, however there was no significant effect of trait IU on any outcome measure after accounting for COVID-specific IU. Notably, COVID-specific IU fully mediated the relationship between trait IU and all four symptom measures. LimitationsThere were several limitations of the current study, including the use of a community sample and high participant attrition. ConclusionsResults suggest that COVID-specific IU predicts mental health outcomes over and above trait IU, extending the existing literature. These findings indicate that uncertainty may be more aversive when it is related to specific distressing situations, providing guidance for developing more specific and individualized interventions. Idiographic treatments which target situation-specific IU may be more efficacious in reducing affective symptoms and related stress during the COVID-19 pandemic or other similar events.

Feeling uncertain despite knowing the risk: Patients with OCD (but not controls) experience known and unknown probabilistic decisions as similarly distressing and uncertain

Patients with obsessive compulsive disorder (OCD) present as risk-averse and avoidant of feared stimuli, yet the literature examining risk aversion in OCD is conflicting. One possible explanation is that patients may exhibit aversion only on ambiguous tasks where the likelihood of possible outcomes is unknown. To test this idea, the current study assigned 30 patients with OCD versus 30 non-psychiatric controls (NPC) to conditions of known versus unknown risk (i.e., probabilities) on the Beads Task. Importantly, the task involved real financial stakes. We also examined self-reported intolerance of uncertainty (IU) as a mechanism. Results revealed a significant risk information × group interaction for certainty about the decision. Specifically, while NPCs felt significantly less certain on the unknown risk (versus known risk) task, the OCD group felt uncertain regardless of risk information. Results also revealed a significant main effect of group for distress after deciding, such that the OCD group was more distressed across all task versions compared to NPCs. Elevated trait IU was associated with higher task-related distress. Results indicate that even when patients with OCD are given information about likelihoods, they still feel uncertain and experience distress. Findings have clinical implications for addressing risk aversion and ambiguity/uncertainty in treatment.

Disentangling trait and daily experiences of uncertainty and meaning in life: implications for daily anxiety, negative affect, and somatic symptoms

ABSTRACTBackgroundAlthough there is growing evidence supporting the association between intolerance of uncertainty (IU) and psychopathology, little is known about the covariation of IU and psychological distress day-to-day. The purpose of this ecological momentary assessment (EMA) study was to examine negative emotional and somatic correlates of trait IU and daily uncertainty, while investigating how a source of stability, meaning in life (MIL), might buffer against deleterious effects of IU and uncertainty.Design and MethodsAdult community members (n = 62) from a mid-size town in the Rocky Mountain region completed baseline measures of IU and MIL and ecological momentary assessments (EMA) of meaning, uncertainty, affect, and somatic symptoms over the course of one week.ResultsResults indicate individuals high in trait IU experience more uncertainty day-to-day and greater distress when they feel uncertain compared to individuals lower in trait IU; however, MIL plays a stronger protective role for high IU compared to low IU individuals.ConclusionsThese findings support and extend previous research showing IU is associated with psychological distress and that MIL may be a critical resource to cultivate. Interventions promoting meaning day-to-day may reduce the effects of uncertainty on the well-being of those highly intolerant of uncertainty.

Race moderates the impact of intolerance of uncertainty on mental health symptoms in Black and White community adults

Racism increases the amount of uncertainty in daily life, which may differentially affect the mental health of individuals from racial minority groups who score high on trait intolerance of uncertainty (IU), or the tendency to experience uncertainty as highly aversive. We examined associations between trait IU and current symptoms of common mental disorders in community samples of Black (N = 125) and White (N = 125) adults ages 18–55 who were matched on age, gender, and educational attainment. Given that data were collected between 2017 and 2021, we also examined pandemic exposure as a moderator of these associations. No mean differences emerged between Black and White adults on trait IU measured with the Intolerance of Uncertainty Scale-12 or on current psychiatric symptoms assessed with the Structured Clinical Interview for DSM-5. Trait IU was more strongly associated with current psychiatric symptoms in Black than White adults, a racial difference that dissipated following pandemic exposure. Present results extend prior work by suggesting the dispositional tendency to find uncertainty aversive is a stronger predictor of mental health symptoms in Black than White adults outside the context of pandemic-related stress. Implications of these findings for understanding the impact of racial- and pandemic-related environmental uncertainty on mental health is discussed.

Нетерпимость к неопределенности и трудности принятия решений у взрослых людей с высокофункциональным аутизмом

<p style="text-align: justify;">Individuals with high-functioning autism have difficulties in decision-making in face of incomplete or ambiguous information, particularly in the context of social interaction. Tasks demanding an immediate response or deviation from the usual behavior make them feel excessive anxiety which restricts their social and professional activity. Attempts to camouflage their conservatism to others are one of the risk factors for comorbid depression. Therefore, they avoid new and non-routine situations, thus restricting their own social activity and professional development. On the other hand, insisting on sameness and clarity may give individuals with autism an advantage in long-lasting monotonous tasks. The aim of this review is to consider these symptoms from the perspective of predictive coding. A range of experimental studies has shown that most of the subjects with autism have difficulty in predicting the outcomes based on the cumulative history of interacting with the environment, as well as updating expectations as new evidence becomes available. These peculiarities of the analysis and pragmatic weighting of information may cause the trait intolerance of uncertainty and novelty avoidance of most people with autism.</p>

Eating disorder pathology and compulsive exercise during the COVID-19 public health emergency: Examining risk associated with COVID-19 anxiety and intolerance of uncertainty.

COVID-19 has led to disruptions in daily living and increased uncertainty about physical, financial, social, and psychological consequences, which may contribute to anxiety, eating disorder (ED) pathology, and compulsive exercise. Individual factors, such as intolerance of uncertainty, may impact risk for ED pathology and CE in response to COVID-19 anxiety. The current study examined associations between COVID-19 anxiety, trait intolerance of uncertainty, and COVID-19 intolerance of uncertainty and ED pathology and compulsive exercise. Undergraduate participants (N = 295) completed a series of online questionnaires between March and April of 2020. COVID-19 anxiety and intolerance of uncertainty were associated with ED pathology, but not compulsive exercise. Additionally, both trait and COVID-19 intolerance of uncertainty moderated associations between COVID-19 anxiety and compulsive exercise and ED pathology. COVID-19 anxiety was more strongly related to compulsive exercise and ED pathology for individuals with lower intolerance of uncertainty. COVID-19 anxiety may increase risk for ED pathology and may be specifically important in determining risk for ED pathology and compulsive exercise among individuals with lower intolerance of uncertainty. These results contribute to a growing body of research aimed at understanding the mental health consequences of the COVID-19 and suggest that individual factors (e.g., anxiety and intolerance of uncertainty) are important in determining risk for ED pathology and compulsive exercise in the context of the pandemic.

The influence of uncertainty and intolerance of uncertainty on anxiety

Background and objectivesAlthough the influence of uncertainty and intolerance of uncertainty (IU) on anxiety pathologies has been well-established, only a few studies examined the interaction between uncertainty and IU in producing anxiety. Meanwhile, there is a lack of research utilizing experimental methods to manipulate the situational uncertainty. Therefore, the current study aimed to more systematically investigate whether and how trait IU interacted with uncertainty in the production of anxiety. Methodsthe current study examined the influence of threat-related uncertainty and IU on anxiety in a lab setting. A variant of the threat-of-shock paradigm was employed to manipulate the uncertainty level. State anxiety and worry were measured immediately before and after this manipulation. Hierarchical linear modeling was used for data analysis. ResultsResults showed that trait IU contributed to elevated state anxiety and worry. Meanwhile, when under imminent threat, uncertainty provoked increased worry but exerted limited influence on state anxiety. The interaction effect of uncertainty and IU on anxiety was not evident in this study. LimitationsResults were based on a non-clinical sample rather than individuals with clinical diagnoses. ConclusionsUncertainty could be regarded as a trigger of worrying thoughts, while IU is an important cognitive vulnerability factor of anxiety and related symptoms. The possible reasons for these findings and their implications were discussed in light of theoretical models of anxiety, worry, and IU.

The Role of Threat Level and Intolerance of Uncertainty (IU) in Anxiety: An Experimental Test of IU Theory

Intolerance of uncertainty (IU) has been proposed as an important transdiagnostic variable within mood- and anxiety-related disorders. The extant literature has suggested that individuals high in IU interpret uncertainty more negatively. Furthermore, theoretical models of IU posit that those elevated in IU may experience an uncertain threat as more anxiety provoking than a certain threat. However, no research to date has experimentally manipulated the certainty of an impending threat while utilizing an in vivo stressor. In the current study, undergraduate participants (N = 79) were randomized to one of two conditions: certain threat (participants were told that later on in the study they would give a 3-minute speech) or uncertain threat (participants were told that later on in the study they would flip a coin to determine whether or not they would give a 3-minute speech). Participants also completed self-report questionnaires measuring their baseline state anxiety, baseline trait IU, and prespeech state anxiety. Results indicated that trait IU was associated with greater state anticipatory anxiety when the prospect of giving a speech was made uncertain (i.e., uncertain condition). Further, findings indicated no significant difference in anticipatory state anxiety among individuals high in IU when comparing an uncertain versus certain threat (i.e., uncertain and certain threat conditions, respectively). Furthermore, results found no significant interaction between condition and trait IU when predicting state anticipatory anxiety. This investigation is the first to test a crucial component of IU theory while utilizing an ecologically valid paradigm. Results of the present study are discussed in terms of theoretical models of IU and directions for future work.

Pathways from uncertainty to anxiety: An evaluation of a hierarchical model of trait and disorder-specific intolerance of uncertainty on anxiety disorder symptoms

Uncertainty is central to anxiety-related pathology and intolerance of uncertainty (IU) appears to be a transdiagnostic risk and maintaining factor. The aim of the present study was to evaluate a hierarchical model to identify the unique contributions of trait and disorder-specific IU (i.e., uncertainty specific to generalised anxiety disorder, social anxiety, obsessive compulsive disorder, and panic disorder) to disorder-specific symptoms, beyond other disorder-specific cognitive vulnerabilities (i.e., negative metacognitive beliefs, fear of negative evaluation, inflated responsibility, and agoraphobic cognitions, respectively). Participants (N=506) completed a battery of online questionnaires. Structural equation modelling was used to evaluate model fit, as well as direct and indirect pathways. Trait and disorder-specific IU were significantly associated with multiple cognitive vulnerability factors and disorder symptoms. Indirect effects between trait IU and symptoms were observed through disorder-specific IU and cognitive vulnerabilities. The relative contribution of trait IU and disorder-specific IU to symptoms varied and theoretical and clinical implications are highlighted. Limitations include the cross-sectional design and reliance on self-report. Avenues for further research include a need for replication and extension of the model in different samples and using experimental and multi-method research methods.

Domain-Specific Intolerance of Uncertainty in Socially Anxious and Contamination-Focused Obsessive–Compulsive Individuals

Intolerance of uncertainty (IU) has been increasingly recognized as a transdiagnostic factor across anxiety disorders and depression and is associated with substantial cognitive, behavioral, and emotional impairment. IU is typically construed as a dispositional tendency to view ambiguous stimuli and unknown outcomes as unacceptably threatening regardless of context, but recent findings suggest that the domain in which uncertainty is encountered may be relevant. Taking that research to the next step, the aim of the present study was to determine whether IU is more salient in concern-congruent versus incongruent domains and whether domain-specific IU is a better predictor of anxiety symptoms than trait IU. A total of 102 undergraduates were recruited into analog socially anxious (SA), obsessive–compulsive contamination (OCC), and nonanxious control (NAC) groups based on responses to measures of SA and OCC symptoms. Both groups reported more domain-congruent IU than trait IU or domain-incongruent IU. The SA group reported more social interaction IU than the OCC and NAC groups; the OCC group reported more cleanliness IU than the SA and NAC groups. Domain-specific IU predicted social anxiety and OCC fears above and beyond trait IU. Results suggest that IU has a substantial context-specific component and should be examined both transdiagnostically and transsituationally.

Trait Versus Situation-Specific Intolerance of Uncertainty in a Clinical Sample with Anxiety and Depressive Disorders

Intolerance of uncertainty (IU) has been most heavily implicated in the development and maintenance of generalised anxiety disorder; however, recent research has supported the transdiagnostic conceptualisation of IU by demonstrating that IU contributes to a broad array of symptoms associated with multiple anxiety and depressive disorders. The aim of this study was to examine IU firstly as a trait variable and secondly in reference to a regularly occurring, diagnostically relevant situation in a large clinical sample (N = 218). A measure of situation-specific IU (the Intolerance of Uncertainty Scale–Situation-Specific Version; IUS-SS) is presented. The IUS-SS was found to have a unitary factor structure and high internal consistency. Participants reported significantly more situation-specific IU compared to trait IU. Discriminant validity was indicated by lack of significant relationships with measures of extraversion and alcohol use. Supporting the convergent validity and transdiagnostic nature of the scale, the IUS-SS was positively associated with neuroticism and symptoms of generalised anxiety disorder and social phobia, and explained unique variance in symptoms of depression and panic disorder above and beyond trait IU. Theoretical and clinical implications are discussed.
