Self-reported intolerance of uncertainty and behavioural decisions

Intolerance of uncertainty and psychological flexibility as predictors of mental health from adolescence to old age

PURPOSE

The COVID-19 pandemic brought with it significant social, economic and health uncertainties. These were proposed to impact young people more compared to adults, leading adolescents to report more mental health problems during the pandemic. The current study examined whether differences in cognitive risk (tolerance of uncertainty) and protective (psychological flexibility) factors accounted for age-related differences in depression and anxiety.

METHODS

These associations were investigated in the COVID-19 Risks Across the Lifespan (CORAL) cohort (N = 2280, 11-89 years).

RESULTS

The results showed that adolescents experienced greater intolerance of uncertainty and lower psychological flexibility compared to adults and older adults. Tolerance of uncertainty did not account for age-related differences in depression or anxiety. However, psychological flexibility conferred more protective advantage for anxiety in adults compared to adolescents.

CONCLUSION

The observed age-related differences in risk and protective factors advance our understanding of developmental vulnerabilities to depression and anxiety. Implications for mental health interventions in the context of future pandemics are discussed.

Systematic Search and Scoping Review of Physicians' Intolerance of Uncertainty and Medical Decision-Making Uncertainties During the COVID-19 Pandemic: A Summary of the Literature and Directions for Future Research

Pandemic-related uncertainties and intolerance of uncertainty (IU) could negatively affect physicians' well-being and functioning, being associated with experiences of distress and problematic decision-making processes. To summarize the available quantitative and qualitative evidence of physicians' IU and decisional uncertainty during COVID-19 and problems associated with it, a systematic search was conducted to identify all relevant articles describing physician uncertainty with regard to medical decision making and well-being in COVID-19 pandemic conditions. Medical, psychological, and preprint databases were searched. Ten articles met all eligibility criteria, with eight describing quantitative and two describing qualitative research outcomes, assessed primarily in European regions and via online surveys. Associations between IU and symptoms of poor mental health and mental health risk factors were widespread, but inconsistencies emerged. Qualitative studies emphasized decisional uncertainty as a stressor for physicians, and quantitative studies suggest it may have fostered more unproven treatment choices. While the prevalence and impact of physician uncertainty under COVID-19 conditions requires further investigation, sighting available literature indicates that IU coincided with experiences of poor mental health and, at least towards the beginning of the pandemic, with willingness to endorse unproven treatments. Efforts to reduce uncertainty-related problems for physicians seem warranted, for example, through normalizing experiences of uncertainty or reducing avoidable uncertainty through maintaining open and timely communication channels.

We only know that we don't know: attachment patterns and psychological coping during the COVID-19 pandemic - the mediation role of intolerance of uncertainty

The global outbreak of the COVID-19 pandemic created sudden changes in many areas of daily life and increased uncertainty about the future. Two studies examined the association between attachment patterns and mental well-being during the pandemic, the mediating role of intolerance of uncertainty (IOU), and factors related to social relationships and self-perceptions. The results of the first study, conducted at the outbreak of the pandemic, indicated that individuals with high levels of attachment anxiety experienced more negative emotions and fewer positive emotions at that time, and that IOU and perceived social support mediated these associations. The results of the second study, conducted several months into the pandemic, indicated an association between attachment anxiety and avoidance, and perceived stress during the time of the pandemic. Results of Study 2 also indicated that IOU mediated the association between attachment anxiety and stress, and that sense of coherence (SOC) mediated the association between attachment anxiety and avoidance, and stress. These findings underscore the adverse psychological effects of uncertain situations, especially for individuals with a fragile foundation of interpersonal support, thus emphasizing the need for action to reduce uncertainty, especially in times of emergency.

Adaptation in Young Military Recruits: Protocol for the Advancing Research on Mechanisms of Resilience (ARMOR) Prospective Longitudinal Study

BACKGROUND

Military services provide a unique opportunity for studying resilience, a dynamic process of successful adaptation (ie, doing well in terms of functioning and symptoms) in response to significant adversity. Despite the tremendous interest in positive adaptation among military service members, little is known about the processes underlying their resilience. Understanding the neurobiological, cognitive, and social mechanisms underlying adaptive functioning following military stressor exposure is essential for enhancing the resilience of military service members.

OBJECTIVE

The primary objective of the Advancing Research on Mechanisms of Resilience (ARMOR) longitudinal study is to characterize the trajectories of positive adaptation among young military recruits in response to basic combat training (BCT), a well-defined, uniform, and 10-week period of intense stress (aim 1), and identify promotive and protective processes contributing to individual variations in resilience (aim 2). The secondary objective is to investigate the pathways by which neurobehavioral markers of self-regulation assessed using electroencephalography and magnetic resonance imaging contribute to adaptive trajectories (aim 3).

METHODS

ARMOR is an ongoing, prospective longitudinal cohort study of young military recruits who recently joined the National Guard but have not yet shipped out for BCT. Participants (N=1201) are assessed at 5 time points over the initial >2 years of military service beginning before BCT (baseline) and followed up at 2 weeks and 6, 12, and 18 months after BCT. Participants complete web-based questionnaires assessing vulnerability and protective factors, mental health, and socioemotional functioning at each time point and a battery of neurocognitive tests at time 0. A subset of participants also complete structured diagnostic interviews and additional self-report measures and perform neurobehavioral tasks before and after BCT during electroencephalography sessions and before BCT only during magnetic resonance imaging sessions.

RESULTS

This UG3/UH3 project was initially funded in August 2017, with the UG3 pilot work completed at the end of 2018. The UH3 phase of the project was funded in March 2019. Study enrollment for the UH3 phase began on April 14, 2019, and ended on October 16, 2021. A total of 1201 participants are enrolled in the study. Follow-up data collection for the UH3 phase is ongoing and projected to continue through February 2024. We will disseminate the findings through conferences, webinars, open access publications, and communications with participants and stakeholders.

CONCLUSIONS

The ARMOR study provides a rich data set to identify the predictors and mechanisms of resilient and nonresilient outcomes in the context of military stressors, which are intended to empirically inform the development of prevention and intervention strategies to enhance the resilience of military trainees and potentially other young people facing significant life challenges.

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 x 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.

Advancing Research on Mechanisms of Resilience (ARMOR) Prospective Longitudinal Study of Adaptation in Young Military Recruits: Protocol and rationale for methods and measures

Background

Military service provides a unique opportunity for studying resilience, a dynamic process of successful adaptation (i.e., doing well in terms of functioning and symptoms) in response to significant adversity. Despite tremendous interest in positive adaptation among military service members, little is known about the processes underlying their resilience. Understanding neurobiological, cognitive, and social mechanisms underlying adaptive functioning following military stressor exposure is essential to enhance the resilience of military service members.

Objectives

The primary objective of the Advancing Research on Mechanisms of Resilience (ARMOR) longitudinal study is to characterize trajectories of positive adaptation among young military recruits in response to Basic Combat Training (BCT), a well-defined, uniform, 10-week period of intense stress (Aim 1) and identify promotive and protective processes contributing to individual variations in resilience (Aim 2). The secondary objective is to investigate pathways by which neurobehavioral markers of self-regulation assessed by electroencephalography (EEG) and magnetic resonance imaging (MRI) contribute to adaptive trajectories (Aim 3).

Methods

ARMOR is an ongoing, prospective longitudinal cohort study of young military recruits who recently joined the National Guard but have not yet shipped for BCT. Participants (N=1,201) are assessed at five timepoints over the initial 2+ years of military service beginning before BCT (baseline) and followed up at 2 weeks, 6, 12, and 18 months post-BCT. At each time point, participants complete online questionnaires assessing vulnerability and protective factors, mental health and social-emotional functioning, and, at Time 0 only, a battery of neurocognitive tests. A subset of participants also complete structured diagnostic interviews, additional self-report measures, and perform neurobehavioral tasks before and after BCT during EEG sessions, and, at pre-BCT only, during MRI sessions.

Results

Study enrollment began April 14, 2019 and ended in October 16, 2021. A total of 1,201 participants are enrolled in the study (68.9% male; mean age = 18.9, SD = 3.0). Follow-up data-collection is ongoing and projected to continue through March 2024. We will disseminate findings through conferences, webinars, open access publications, and communications with participants and stakeholders.

Conclusions

Results are expected to elucidate how young military recruits adapt to military stressors during the initial years of military service. Understanding positive adaptation of military recruits in the face of BCT has implications for developing prevention and intervention strategies to enhance resilience of military trainees and potentially other young people facing significant life challenges.

Intolerance of uncertainty and functional connectivity of the anterior insula during anticipation of unpredictable reward

Individuals with high intolerance of uncertainty (IU) tend to display maladaptive cognitive, behavioral, physiological, and/or neural responses during anticipation of uncertain or ambiguous outcomes, both positive and negative in valence. Importantly, high IU has been proposed as a key transdiagnostic phenotypic risk factor for the onset and maintenance of several psychiatric disorders. Within the context of reward processing, high IU has been related to dysfunctional reward anticipation, which may be mediated by hyperactive anterior insula (AIC) response to uncertainty. The present study further investigated the relationship between the AIC and IU by examining the association between individual differences in IU and task-based functional connectivity of the right AIC using functional magnetic resonance imaging (fMRI). Participants (N = 171) completed a self-report measure of IU and a reward anticipation task during fMRI. Generalized psychophysiological interaction (gPPI) analyses were performed with a seed in the right AIC. In the U-threat model, we found that greater self-reported levels of IU were correlated with increased functional connectivity between the right AIC and the dorsal anterior cingulate cortex (dACC) and the right dorsolateral prefrontal cortex (dlPFC). In the P-threat model, we did not find these associations, perhaps indicating that they may be more robust during uncertainty. These preliminary findings suggest that parts of salience and central executive control networks may be impacted by and underlie the expression of IU. Future studies should examine the generalizability of these findings to clinical populations and investigate how disruption of these functional networks may contribute to psychopathology.

COVID-19 pandemic and tourism: The impact of health risk perception and intolerance of uncertainty on travel intentions

Understanding tourist behavior during and after major tourism crises is essential to help destinations recover. The COVID-19 pandemic - a period of uncertainty and risk - makes it relevant to assess factors that influence travel intentions. There has been little research on tourist behavior during health crises and, in particular, on perceived health risk and uncertainty effects on travel intentions. This study was carried out at the beginning of the pandemic in Brazil and aims to investigate the role of health risk perception and intolerance of uncertainty on travel intentions for 2020 and 2021. We applied an online survey to 1150 Brazilian participants from April to May 2020. Our findings indicate that perceived COVID-19 severity, perceived probability of infection, and expected duration of the pandemic are significant predictors of travel intentions for both years. This paper contributes to a deeper understanding of crisis-resistant tourists' characteristics and provides insights for destinations' recovery.

Dispositional causes of burnout, satisfaction, and performance through the fear of COVID-19 during times of pandemic

Rooted in research into personality, we propose that the Big Five traits would be related to fear of COVID-19 (FOC), which in turn would lead to heightened job burnout, reduced job satisfaction, and decreased performance. Utilizing a three-wave time-lagged design, we collected our data from employees working in the United States and Canada (N = 300 × 3). We found good support for our hypotheses. Extraversion, neuroticism, and conscientiousness had significant direct effects on FOC. Fear of COVID-19 was positively related to job burnout and negatively related to job satisfaction and performance. Extraversion, neuroticism, and conscientiousness had significant indirect effects on burnout, job satisfaction, and job performance via FOC. Hence, this study identifies a key mechanism, an individual's worry about losing their valuable resources (e.g. their health, and that of their family members and friends, etc.), through which selected dimensions of personality might affect employees' work outcomes. We discuss our findings and provide suggestions for future research in this domain.

Decision-making in uncertain contexts: The role of autonomic markers in resolving indecision

Although impulsivity is associated with an increased willingness to make risky decisions, uncertainty intolerance may also contribute to maladaptive decision-making behavior, where individuals neglect to pursue potential rewards even when probabilities for success are in their favor. Several theories have sought to explain the neural systems that guide decision-making in this context, with evidence supporting a role for increased sympathetic activation. However, it remains unclear whether the sympathetic system is associated with greater apprehension in response to uncertain outcomes, or whether it serves to guide behavioral decisions in the context of this uncertainty. Furthermore, although postulated as a within-person process, most research has examined the association between decision behavior and sympathetic activation at the between-person level. We hypothesize that in the context of uncertainty between-person differences in skin conductance will be associated with longer deliberation times; whereas within-person trial-level increases in skin conductance will be associated with a tendency to reject uncertain options. Data were collected from n = 56 children aged 7-11 years, using a computerized card game in which children chose to accept or reject cards of varying point value at varying levels of probability. Skin conductance level (SCL) was recorded throughout the task. No significant between-person associations emerged. However, within-person analyses indicated that momentary deliberation time moderated the association between momentary skin-conductance and decision outcome. This moderation was such that for trials during which the individual deliberated longer (i.e., was more indecisive), a concurrent increase in skin conductance was associated with a significantly higher likelihood of rejecting the card. The within-person nature of these results suggests that skin conductance may help in resolving indecision in the context of uncertainty.

Intolerance of uncertainty prospectively predicts the transdiagnostic severity of emotional psychopathology: Evidence from a Veteran sample

Intolerance of uncertainty (IU) has been conceptualized as a transdiagnostic vulnerability for emotional psychopathology, but few studies have tested whether it prospectively predicts emotional psychopathology, and none have utilized transdiagnostic and clinician-rated outcomes. To fill this gap, the present study tested whether IU prospectively predicted the clinician-rated severity of transdiagnostic emotional psychopathology six months later in a treatment-seeking Veteran sample. Participants completed the Intolerance of Uncertainty 12-item scale (IUS-12) and the Structured Clinical Interview for the DSM-5 (SCID-5) at Time 1 and again six-months later (Time 2); assessed emotional disorders included both anxiety-related disorders (i.e., post-traumatic stress disorder, generalized anxiety disorder, panic disorder, social anxiety disorder, obsessive compulsive disorder, specific phobia) and depressive conditions (i.e., major depressive disorder and persistent depressive disorder). Linear regression analyses revealed a bidirectional prospective relation between IU and emotional psychopathology, wherein higher Time 1 IUS-12 predicted greater Time 2 emotional disorder severity and greater Time 1 emotional disorder severity predicted higher Time 2 IUS-12. Follow-up analyses revealed that IU prospectively predicted the maintenance (but not the development) of anxiety-related issues, whereas prediction of Time 2 depression was nullified when controlling for Time 1 anxiety pathology. These findings implicate IU as a transdiagnostic vulnerability for emotional psychopathology and suggest the construct can be particularly useful as a treatment target and prognostic indicator for anxiety-related conditions.

Identifying the contingencies of self-worth associated with eating disorder symptoms: The use of choice-based conjoint analysis

OBJECTIVE

Self-worth contingent on shape/weight is a diagnostic criterion and key maintaining factor for eating disorders. However, the role of other contingencies of self-worth (i.e., domains in which self-worth is invested) is largely unknown. Moreover, research has relied on self-ratings of contingency strength, which are subject to distortion through socially desirable responding and limited self-awareness, and may have limitations in terms of ecological validity. To overcome these limitations, the present study investigated a broad range of contingencies of self-worth in relation to eating disorder pathology and employed a choice-based conjoint (CBC) approach for assessing these contingencies.

METHOD

Young women and men from the community (N = 428) completed a CBC task to assess the domains in which self-worth is invested, the Eating Disorder Examination Questionnaire (EDE-Q) to assess eating disorder symptomatology, and the Balanced Inventory of Desirable Responding to assess socially desirable responding.

RESULTS

Beta regression analyses showed that CBC thinness and athletic competence predicted higher scores on all EDE-Q scales. CBC muscularity and facial attractiveness predicted higher scores, while coping ability and quality of relationships predicted lower scores, on various aspects of eating disorder symptoms. CBC social acceptance predicted lower eating disorder symptoms in males only.

DISCUSSION

The findings suggest that a broader range of contingencies of self-worth beyond shape/weight are relevant to eating disorder pathology and should be considered as potential underlying mechanisms and treatment targets. In addition, this first use of the CBC method in eating disorder research provides initial support for its validity and utility.

Future Expectations and Internet Addiction Among Adolescents: The Roles of Intolerance of Uncertainty and Perceived Social Support

Internet addiction is a common and challenging problem among adolescents. Previous studies have shown that future time orientation is an important protective factor against internet addiction. In this study, the mediating effect of intolerance of uncertainty and the moderating role of perceived social support were examined on the association between future expectations, regarded as the "prospective life course" perspective of future time orientation, and internet addiction among adolescents. A total of 1,006 Chinese adolescents (54% male and 46% female; Mage = 15.42 years, SD = 1.32) recruited from middle schools completed questionnaires. Results indicated that future expectations were significantly negatively associated with internet addiction, and the link was mediated by intolerance to uncertainty in adolescents. Further, the latent moderated structural equation showed that perceived social support moderated the association between future expectations and intolerance of uncertainty. The association was significant only for adolescents with a higher level of perceived social support. The findings of this study provide specific guidelines for how to prevent adolescent internet addiction.

How Patients with an Uncertain Diagnosis Experience Intolerance of Uncertainty: A Grounded Theory Study

PURPOSE

To develop a conceptual framework to explain how patients with uncertain diagnoses experience intolerance of uncertainty (IU) in order to achieve an in-depth understanding of the process of facing uncertainty in this population.

PATIENTS AND METHODS

A grounded theory study using semi-structured interviews was conducted with 21 patients with uncertain diagnoses in China from December 2018 to March 2019. The coding process followed the procedures of Strauss and Corbin: open coding, axial coding, and selective coding.

RESULTS

We developed a conceptual framework called 'Facing an Uncertain Diagnosis'. This framework considers not only the external and internal context of IU generation but also the ongoing process of how IU impacts patients' psychological status, cognitive response, behavior, and decision making.

CONCLUSION

We suggest that healthcare professionals should be aware of the high level of IU and its psychological, cognitive, and behavioral manifestations in patients with uncertain diagnoses. Healthcare professionals should also be more cautious in shared decision making with patients with uncertain diagnoses.

The Mediating Role of Entrepreneurial Mindset between Intolerance of Uncertainty and Career Adaptability

Entrepreneurship education has been employed broadly in higher education, and one of the most popularly targeted outcomes is enhancing entrepreneurial mindset. However, the role of entrepreneurial mindset has not been examined in relation to career adaptability, which has been acknowledged as an important resource for adjustment, especially with the increased uncertainty caused by COVID-19. The current study investigated the relations among intolerance of uncertainty—specifically its sub-factors, prospective anxiety and inhibitory anxiety—career adaptability, and entrepreneurial mindset in 274 Korean college students facing school-to-work transition during COVID-19. The study conducted path analysis and evaluated the mediating effect of entrepreneurial mindset, using a 95% bootstrapping confidence interval, to better understand the role of entrepreneurial mindset in general career development in the context of uncertainty. The results found that inhibitory anxiety had an inverse association with career adaptability and entrepreneurial mindset, while prospective anxiety had a positive relation with career adaptability and entrepreneurial mindset. Entrepreneurial mindset and career adaptability showed a significantly positive relation, and the mediating role of entrepreneurial mindset between intolerance of uncertainty and career adaptability was also supported. Discussions on the role of entrepreneurial mindset are initiated and practical implications for entrepreneurship education are proposed along with the limitations of the study.

Intolerance of uncertainty and reactions to the COVID-19 pandemic

The COVID-19 pandemic has presented a threat to mental health worldwide. The current study aims to investigate the role of intolerance of uncertainty in cognitive, emotional and behavioral reactions to this pandemic and propose a path model of these reactions. In the first two months of the COVID-19 pandemic in Slovakia, participants in a general sample (n = 1,011) as well as an older adult sample (n = 655) completed measures regarding intolerance of uncertainty, mental health (anxiety, well-being, perceived stress) and adherence to preventive measures. Two rounds of data collection were carried out in the first sample. Intolerance of uncertainty was found to be related to mental health indicators and the structural equation model showed a direct and indirect effect on them as well as on the adherence to preventive measures. However, the comparison of data from different time points has brought inconsistent results. The findings highlight the role of intolerance of uncertainty in reaction to threat and indicate the potential of uncertainty reduction e.g., getting clear messages from authorities, as a way of decreasing mental health problems.

Mental Capacity, Decision-Making and Emotion Dysregulation in Severe Enduring Anorexia Nervosa

Severe and Enduring Anorexia Nervosa (SE-AN) is a chronic eating disorder characterized by long-term starvation and its physical and psychological sequelae, and severe loss of quality of life. Interactions between neurobiological changes caused by starvation, vulnerability (personality) traits, and eating behaviors play a role. Several other factors, such as increased fear and decreased social cognition, have also been found in relation to SE-AN. With this in mind, we aim to add to the understanding of SE-AN by introducing the concept of mental capacity (MC), which refers to the ability to understand and process information-both on a cognitive and an emotional level-and then make a well-informed choice. MC may be an important construct within the context of SE-AN. Furthermore, we will argue how impaired decision-making processes may underlie, fuel, or contribute to limited MC in SE-AN. We will speculate on the importance of dysfunctional emotion processing and anxiety-related processes (e.g., a high intolerance of uncertainty) and their potential interaction with decision-making. Lastly, we will propose how these aspects, which to our knowledge have previously received little attention, may advise research and treatment or help in dealing with the "want but cannot" situation of life-threatening AN.

Acute stress enhances tolerance of uncertainty during decision-making

Acute stress has been shown to influence reward sensitivity, feedback learning, and risk-taking during decision-making, primarily through activation of the hypothalamic pituitary axis (HPA). However, it is unclear how acute stress affects decision-making among choices that vary in their degree of uncertainty. To address this question, we conducted two experiments in which participants repeatedly chose between two options-a high-uncertainty option that offered highly variable rewards but was advantageous in the long-term, and a low-uncertainty option that offered smaller yet more consistent rewards. The Socially Evaluated Cold Pressor Task (SECPT) was utilized to induce acute stress. Participants in Experiment 1 (N = 114) were exposed to either the SECPT or a warm-water control condition and then completed the decision-making under uncertainty task. Compared to the control condition, those exposed to the acute stress manipulation chose the high-uncertainty option that provided highly variable but larger rewards over the option that provided stable, smaller rewards. Experiment 2 (N = 95) incorporated a salivary cortisol measure. Results replicated the behavioral findings in Experiment 1 and demonstrated that the acute stress manipulation increased salivary cortisol. This work suggests that moderate acute stress is associated with tolerance of outcome variability in contexts that depend on learning to maximize rewards.

Functional connectivity of the anterior insula associated with intolerance of uncertainty in youth

Intolerance of uncertainty (IU) is a trait characteristic marked by distress in the face of insufficient information. Elevated IU has been implicated in the development and maintenance of anxiety disorders, particularly during adolescence, which is characterized by dramatic neural maturation and the onset of anxiety disorders. Previous task-based work implicates the bilateral anterior insula in IU. However, the association between anterior insula intrinsic functional connectivity (iFC) and IU has not been examined in adolescents. Fifty-eight healthy youth (mean age = 12.56; 55% boys) completed the Intolerance of Uncertainty Scale for Children (IUSC-12) and a 6-minute resting state fMRI scan. Group-level analyses were conducted using a random-effects, ordinary least-squares model, including IUSC-12 scores (Total, Inhibitory subscale, Prospective subscale), and three nuisance covariates (age, sex, and mean framewise displacement). IUSC-12 Inhibitory subscale scores were predictive of iFC between the left and right anterior insula and right prefrontal regions. IUSC-12 Prospective subscale scores significantly predicted iFC between the anterior insula and the anterior cingulate cortex. IUSC-12 total scores did not predict significant iFC of the bilateral anterior insula. Follow-up analyses, including anxiety (MASC Total Score) in the models, failed to find significant results. This could suggest that the associations found between IUSC-12 scores and anterior insula iFC are not unique to IU and, rather, reflect a broader anxiety-related connectivity pattern. Further studies with larger samples are needed to tease apart unique associations. These findings bear significance in contributing to the literature evaluating the neural correlates of risk factors for anxiety in youth.

Intolerance of uncertainty and eating disorder behaviour: Piloting a consumption task in a non-clinical sample

BACKGROUND AND OBJECTIVES

Intolerance of uncertainty (IU) is a transdiagnostic process contributing to the maintenance of anxiety disorders, and is a potential target for treatment. Recent literature has investigated IU as a cognitive process underpinning pathological fear and anxiety in Anorexia Nervosa (AN). The current study was designed to examine trait and state IU, and their relationship to restrictive eating disorder symptoms, anxiety, worry, cognitive rigidity and eating behaviour.

METHODS

A sample of undergraduate women (N = 85) completed measures of eating disorder symptoms, IU, cognitive rigidity and worry. Participants were randomised to complete an eating task under one of two conditions: the "certain" condition received a high-calorie meal and nutritional information, while the "uncertain" condition received the meal alone. During the meal, state IU and state anxiety were examined at three time-points (baseline, pre-eating, post-eating).

RESULTS

Trait IU was correlated with cognitive rigidity, worry, global eating disorder symptoms, and, in particular, dietary restraint. No differences emerged between conditions with respect to eating-related anxiety, or amount of food eaten. Controlling for condition and eating disorder symptoms, state IU predicted pre-eating anxiety. Beyond the contribution of condition, BMI and eating disorder symptoms, state IU predicted consumption, specifically greater dietary restriction.

LIMITATIONS

The study employed a non-clinical sample.

CONCLUSIONS

IU may be implicated in a rigid cognitive style, the anxiety response to energy-dense food, and restrictive eating behaviour. Should these findings be replicated in a clinical sample, then IU might emerge as an adjunctive treatment target for AN.

Psychological distress in women with recurrent spontaneous abortion: A case-control study

Objective

The aim of the present study was to evaluate psychological problems in women with recurrent spontaneous abortion (RSA).

Materials and Methods

In this case-control study, 115 women with RSA were assigned to the case group and 240 non-pregnant women comprised the control group. The revised version of the Symptom Checklist-90 (SCL-90-R) and the Intolerance of Uncertainty scale (IUS) were used for assessing mental health problems.

Results

The results showed that the mean Global Severity Index (GSI) of the SCL-90-R and the IUS scores in the case and control groups were 109.10±59.85 and 68.91±22.17, and 82.98±52.99 and 59.19±23.01, respectively. GSI was the strongest predictor of RSA [odds ratio (OR)=6.43; 95% confidence interval (CI): 3.52-11.72]. The chance estimate of RSA was approximately 2.1 times higher in women in rural areas (OR=2.07; 95% CI: 1.16-3.69), and 2 times higher at 12 months after the last pregnancy (OR=1.99; 95% CI: 1.42-2.78).

Conclusion

Psychological problems are greater after RSA. Therefore, it is suggested that the treatment of RSA emphasizes psychological counseling and psychological management.

Talking about risk in the context of genomic tests (TARGET): development and evaluation of an educational program for clinicians

Purpose

Gene expression profiling (GEP) test scores calculate risks of recurrence and likely benefit of adjuvant chemotherapy in ER-positive, HER2-negative, early-stage breast cancer. As health literacy and numeracy skills in the general population are poor, healthcare professionals (HCPs) require a wide repertoire of communication skills to explain clearly risk of recurrence scores (RSs) and uncertainty. We developed and evaluated an educational program for HCPs discussing GEP test results and adjuvant treatment.

Methods

Eight-hour workshops contained elements aimed at improving knowledge, communication skills and self-awareness; these included the science underpinning GEP tests, an interactive risk psychology lecture, exercises and facilitated group discussions regarding seven filmed scenarios involving discussions about high, intermediate and low RSs. Attendees were recorded explaining RSs with patient simulators pre and post workshop. Researchers, blinded to time point, analysed recordings using a study-specific scoring system. Primary objective outcomes were improvements post workshop in HCPs’ competence and confidence when communicating 17 pre-specified key information areas. We estimated odds ratios (OR) using conditional logistic regression to compare pre- and post-workshop scores.

Results

65 HCPs attended. Objective analyses revealed significant positive shifts post workshop which included explaining GEP tests (OR 2.98; 95% CI 1.38–6.42; P = .001), recurrence RSs (OR 3.99; 95% CI 1.72–9.25; P < .001), benefits of chemotherapy (OR 3.99; 95% CI 1.82–8.75; P < .001; and harms OR 2.31; 95% CI 1.37–3.92; P < .001) using jargon free language (OR 5.29; 95% CI 2.27–12.35; P < .001). Patient simulator assessments also showed significant improvements as did HCPs’ self-assessments and ratings of their self-confidence when discussing different GEP tests with diverse patient types (P < .001).

Conclusion

These short, intensive, interactive TARGET workshops significantly improved HCPs’ communication about GEP results in ways likely to promote more informed decision-making by patients about chemotherapy.

Brief Report: The Impact of Sensory Hypersensitivity and Intolerance of Uncertainty on Anxiety in Williams Syndrome

This study explored the interrelationship between intolerance of uncertainty, sensory hyper-sensitivity and anxiety in Williams syndrome (WS). Thirty-two parents or guardians of individuals with WS (M_age = 24.76 years, SD = 7.55) were included. Associations between anxiety, intolerance of uncertainty, sensory hyper-sensitivity, and ASD symptoms were assessed. Linear regression analysis revealed that intolerance of uncertainty and sensory hyper-sensitivity were unique independent predictors of anxiety, while social communication score was not. There was evidence of a mediating effect of sensory hyper-sensitivity on the relationship between intolerance of uncertainty and anxiety. These findings bear strong resemblance to the pattern seen in ASD and emphasize the need for development of anxiety interventions that attempt to reduce negative beliefs about unpredictable situations in WS.

Predicting intolerance of uncertainty in individuals with eating disorder symptoms

BACKGROUND

Intolerance of Uncertainty (IU) is recognized for its contribution to various psychopathologies, in particular anxiety and depression. Studies highlight the relevance of IU for Eating Disorders (EDs) however, potential factors contributing to IU in EDs remain unstudied.

METHODS

Three hundred and forty-nine women with ED symptoms and 214 individuals without ED symptoms were recruited and compared on levels of IU, insecure (anxious and avoidant) attachment styles, extraversion and openness. Secondly, the contribution of these factors to IU were tested.

RESULTS

Compared to the non-ED group, the ED group scored higher on IU, insecure attachment, and lower on extraversion and openness. Regression analyses confirmed that higher insecure attachment, and lower extraversion predicted higher IU scores in the ED group, and that insecure attachment predicted higher IU scores in the non-ED group.

CONCLUSIONS

Results confirm the relevance of IU to ED, and demonstrate that personality traits and insecure attachment styles contribute to IU in ED. Findings add to the growing literature on IU in ED and suggest that people with EDs may benefit from clinical interventions targeting IU.

Intolerance of Uncertainty Scale: Measurement invariance among adolescent boys and girls and relationships with anxiety and risk taking

BACKGROUND AND OBJECTIVES

Adolescence-related increases in both anxiety and risk taking may originate in variability in Intolerance of Uncertainty (IU), rendering the study of IU of importance. We therefore studied the psychometric properties of the Intolerance of Uncertainty Scale-Short version (IUS-12), including its associations with trait anxiety and risk taking, among adolescents.

METHODS

A sample of 879 Dutch adolescents, from diverse educational levels, and with an equal distribution of boys and girls, was classically tested. To obtain indices of IU, and self-reported trait anxiety and need for risk taking, questionnaires were administrated; to obtain an index of risk taking behavior, adolescents performed a risk taking task.

RESULTS

Multi-group Confirmatory Factor Analyses revealed that the IUS-12 consists of a Prospective and an Inhibitory IU subscale, which are partially measurement invariant across sex. Cronbach's alphas and item-total correlations revealed that the IUS-12 and its subscales have reasonable-to-good internal consistency. Correlational analyses support convergent validity, as higher IUS-12 scores were related to, respectively, higher and lower levels of self-reported trait anxiety and need for risk taking. However, we found no relationship between IUS-12 scores and risk taking behavior, operationalized by performance on the risk taking task.

LIMITATIONS

A community, instead of clinical, sample was included. Also, IU was measured by a paper-and-pencil version of the IUS-12, instead of a computerized version.

CONCLUSIONS

The IUS-12 has good psychometric properties and may be a central measure to assess IU, which enables to explain the adolescence-related increase in both anxiety and risk taking.

Intolerance of Uncertainty: A Temporary Experimental Induction Procedure

Background and Objectives

Intolerance of uncertainty (IU) is a trans-diagnostic construct involved in anxiety and related disorders. Research focused on cross-sectional reporting, manipulating attitudes toward objective and impersonal events or on treatments designed to reduce IU in clinical populations. The current paper presents an experimental procedure for laboratory manipulations of IU and tests mediation hypotheses following the Intolerance of Uncertainty Model.

Methods

On pre-test, undergraduate volunteers (Study 1, n = 43;68% women. Study 2, n = 169;83.8% women) were asked to provide an idiosyncratic future negative life event. State-IU, Worry, Positive and Negative Affect were assessed after that a standardized procedure was used to identify event’s potential negative consequences. The same variables were assessed on post-test, after that participants were asked to read-through increasing and decreasing IU statements.

Results

Temporary changes on IU were consistently reproduced in both studies. Participants receiving increasing IU instructions reported greater state-IU, Worry and Negative Affect than those receiving decreasing IU instructions. However, this latter condition was not different from a control one (Study 2). Both studies revealed significant indirect effects of IU induction instructions on Worry and Negative Affect through state-IU.

Limitations

Both studies used undergraduate psychology students samples, younger than average population and predominantly female. Experimental manipulation and outcome measures belongs to the same semantic domain, uncertainty, potentially limiting generalizability.

Conclusions

Results supported the feasibility and efficacy of the proposed IU manipulation for non-clinical sample. Findings parallel clinical research showing that state-IU preceded Worry and Negative Affect states.
