Intolerance of uncertainty and negative metacognitive beliefs as transdiagnostic mediators of repetitive negative thinking in a clinical sample with anxiety disorders. J Anxiety Disord 2013; 27:216-24. [PMID: 23474912 DOI: 10.1016/j.janxdis.2013.01.006] [Citation(s) in RCA: 49] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2012] [Revised: 01/21/2013] [Accepted: 01/22/2013] [Indexed: 11/20/2022]
Abstract
This study aimed to replicate and extend a hierarchical model of vulnerability to worry, with neuroticism and extraversion as higher-order factors and negative metacognitions and intolerance of uncertainty as second-order factors. The model also included a transdiagnostic measure of repetitive negative thinking (RNT) and depression symptoms as outcome variables to determine whether relationships would extend beyond worry, which has traditionally been studied within the context of generalized anxiety disorder (GAD). Participants (N=99) were referrals to a specialist anxiety disorders clinic with a principal anxiety disorder who completed a battery of self-report questionnaires assessing neuroticism, extraversion, metacognitions, intolerance of uncertainty, worry, RNT, and depression symptoms. Mediational analyses using bootstrapping provided support for transdiagnostic and diagnosis-specific mediation effects. Negative metacognitions fully mediated the relationship between neuroticism and RNT for the whole sample and for subsamples with and without GAD. Intolerance of uncertainty mediated the relationship between neuroticism and worry (for the whole sample and for those with GAD) and between neuroticism and RNT (for those with GAD). Implications for theory, treatment, and nosology are discussed.

Intolerance of uncertainty as a vulnerability factor for hoarding behaviors. J Affect Disord 2013; 145:227-31. [PMID: 22921482 DOI: 10.1016/j.jad.2012.08.003] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2012] [Accepted: 08/02/2012] [Indexed: 11/22/2022]
Abstract
BACKGROUND Intolerance of uncertainty (IU) has been identified as a key vulnerability factor among numerous anxiety related conditions. It has been suggested that individuals engage in uncertainty-motivated behaviors such as avoidance, as a way to cope with ambiguous and potentially distressing situations. Patterns of behavioral avoidance have also been observed in a substantial number of hoarding patients and are thought to directly contribute to the avoidance of discarding. However, no studies to date have examined the potential relationship between IU and hoarding. The primary aim of the current investigation was to examine the association between IU and hoarding behaviors. METHOD Participants consisted of 279 college students from a large southern university. RESULTS Results revealed that IU was a significant predictor of hoarding severity after controlling for relevant covariates. Moreover, when looking at the relationships among IU subfactors and hoarding, results indicated that Factor 1 was significantly associated with hoarding severity whereas Factor 2 was not. LIMITATIONS Future research should attempt to replicate the findings within clinical populations. Additionally, due to the cross sectional nature of the study, future work should utilize a longitudinal design. CONCLUSIONS The current study provides additional evidence that IU is an important individual difference variable associated with various anxiety related conditions. Moreover, our findings revealed that IU is a unique and robust predictor of hoarding behaviors. Increasing our knowledge of vulnerability factors in compulsive hoarding has important implications for the classification of this disorder within DSM-V. Additionally, this information could inform future research and treatment programs.

Abstract
BACKGROUND Social Phobia (SP) is an anxiety disorder that frequently co-occurs with obsessive-compulsive disorder (OCD); however, studies that evaluate clinical factors associated with this specific comorbidity are rare. The aim was to estimate the prevalence of SP in a large multicenter sample of OCD patients and compare the characteristics of individuals with and without SP. METHOD A cross-sectional study with 1001 patients of the Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders using several assessment instruments, including the Dimensional Yale-Brown Obsessive-Compulsive Scale and the Structured Clinical Interview for DSM-IV Axis I Disorders. Univariate analyses were followed by logistic regression. RESULTS Lifetime prevalence of SP was 34.6% (N=346). The following variables remained associated with SP comorbidity after logistic regression: male sex, lower socioeconomic status, body dysmorphic disorder, specific phobia, dysthymia, generalized anxiety disorder, agoraphobia, Tourette syndrome and binge eating disorder. LIMITATIONS The cross-sectional design does not permit the inference of causal relationships; some retrospective information may have been subject to recall bias; all patients were being treated in tertiary services, therefore generalization of the results to other samples of OCD sufferers should be cautious. Despite the large sample size, some hypotheses may not have been confirmed due to the small number of cases with these characteristics (type 2 error). CONCLUSION SP is frequent among OCD patients and co-occurs with other disorders that have common phenomenological features. These findings have important implications for clinical practice, indicating the need for broader treatment approaches for individuals with this profile.

Abstract
The Intolerance of Uncertainty Model was initially developed as an explanation for worry within the context of generalized anxiety disorder. However, recent research has identified intolerance of uncertainty (IU) as a possible transdiagnostic maintaining factor across the anxiety disorders and depression. The aim of this study was to determine whether IU mediated the relationship between neuroticism and symptoms related to various anxiety disorders and depression in a treatment-seeking sample (N=328). Consistent with previous research, IU was significantly associated with neuroticism as well as with symptoms of social phobia, panic disorder and agoraphobia, obsessive-compulsive disorder, generalized anxiety disorder, and depression. Moreover, IU explained unique variance in these symptom measures when controlling for neuroticism. Mediational analyses showed that IU was a significant partial mediator between neuroticism and all symptom measures, even when controlling for symptoms of other disorders. More specifically, anxiety in anticipation of future uncertainty (prospective anxiety) partially mediated the relationship between neuroticism and symptoms of generalized anxiety disorder (i.e. worry) and obsessive-compulsive disorder, whereas inaction in the face of uncertainty (inhibitory anxiety) partially mediated the relationship between neuroticism and symptoms of social anxiety, panic disorder and agoraphobia, and depression. Sobel's test demonstrated that all hypothesized meditational pathways were associated with significant indirect effects, although the mediation effect was stronger for worry than other symptoms. Potential implications of these findings for the treatment of anxiety disorders and depression are discussed.

Abstract
BACKGROUND AND OBJECTIVES Recent research suggests that intolerance of uncertainty (IU), most commonly associated with generalized anxiety disorder, also contributes to symptoms of social phobia. This study examines the relationship between IU and social anxiety symptoms across treatment. METHOD Changes in IU, social anxiety symptoms, and depression symptoms were examined following cognitive behavior group therapy (CBGT) for social phobia (N=32). RESULTS CBGT led to significant improvements in symptoms of social anxiety and depression, as well as reductions in IU. Reductions in IU were associated with reductions in social anxiety but were unrelated to improvements in depression symptoms. Reductions in IU were predictive of post-treatment social phobia symptoms after controlling for pre-treatment social phobia symptoms and changes in depression symptoms following treatment. LIMITATIONS The relationship between IU and social anxiety requires further examination within experimental and longitudinal designs, and needs to take into account additional constructs that are thought to maintain social phobia. CONCLUSIONS Current findings suggest that the enhancing tolerance of uncertainty may play a role in the optimal management of social phobia. Theoretical and clinical implications are discussed.

Abstract
Intolerance of uncertainty (IU) - a dispositional characteristic resulting from negative beliefs about uncertainty and its implications - may be an important construct in anxiety disorders and depression. Despite the potential importance of IU, clinical data on the construct remains relatively scant and focused on generalized anxiety disorder and obsessive-compulsive disorder. The present study systematically investigated IU, as measured by the Intolerance of Uncertainty Scale-12 (IUS-12), across groups diagnosed with anxiety disorders (i.e., social anxiety disorder, panic disorder, generalized anxiety disorder, obsessive-compulsive disorder) or depression (clinical sample: n=376; 61% women), as well as undergraduate (n=428; 76% women) and community samples (n=571; 67% women). Analysis of variance revealed only one statistically significant difference in IUS-12 scores across diagnostic groups in the clinical sample; specifically, people with social anxiety disorder reported higher scores (p<.01; η(2)=.03) than people with panic disorder. People diagnosed with an anxiety disorder or depression reported significantly and substantially higher IUS-12 scores relative to community and undergraduate samples. Furthermore, IUS-12 score distributions were similar across diagnostic groups as demonstrated by Kernel density estimations, with the exception of panic disorder, which may have a relatively flat distribution of IU. Response patterns were invariant across diagnostic groups as demonstrated by multi-group confirmatory factor analyses, but varied between clinical and nonclinical samples. Overall, the findings suggest IU may serve as an important transdiagnostic feature across anxiety disorders and depression. In addition, robust support was found for the proposed 2-factor model of the IUS-12. Comprehensive findings, implications, and future research directions are discussed.

Abstract
OBJECTIVE To test whether intolerance of uncertainty (IU) is related to eating disorder (ED) pathology. METHOD Thirty individuals with anorexia nervosa (AN), 19 with bulimia nervosa (BN), and 28 healthy control women (CW) completed the Intolerance of Uncertainty Scale (IUS). RESULTS AN and BN groups showed higher IU compared with CW. In AN and BN, Harm Avoidance and Depression scores were positively correlated with IU. In AN but not BN, IU was related positively to Drive for Thinness and Body Dissatisfaction. DISCUSSION Elevated IU is associated with AN and BN. Anxious traits may be inherent in EDs and IU could be a developmental factor contributing to anxiety, mood, and ED behavior in AN and BN.

Abstract
Intolerance of uncertainty (IU) has been found to be involved in several anxiety disorders, including generalized anxiety disorder and obsessive-compulsive disorder (OCD). Few studies have examined the role of IU in health anxiety (HA)/hypochondriacal concerns (HC). We conducted two studies exploring the associations between IU and HA/HC. The first study included undergraduates (n = 114) and indicated an association between IU and several HA/HC indices. When controlling for neuroticism, worry about illness was the single index of HA/HC that remained associated with IU. In the second study among bereaved adults (n = 126), IU was associated with one index of HA/HC but not when neuroticism and anxiety sensitivity were controlled. In both studies, IU was found to be more strongly associated with OCD symptoms and worry than with HA/HC.

Abstract
AbstractThis study explored whether intolerance of uncertainty and/or meta-worry discriminate between non-clinical individuals and those diagnosed with generalised anxiety disorder (GAD group). The participants were 107 GAD clients and 91 university students. The students were divided into two groups (high and low GAD symptom groups). A multivariate analysis of covariance (MANCOVA) adjusting for age indicated that intolerance of uncertainty distinguished between the low GAD symptom group and the high GAD symptom group, and between the low GAD symptom group and the GAD group. Meta-worry distinguished all three groups. A discriminant function including intolerance of uncertainty and meta-worry classified 94.4% of the GAD group and 97.9% of the low GAD symptom group. Only 6.8% of the high GAD symptom group was classified correctly, 77.3% of the high GAD symptom group was classified as GAD. Findings indicated that intolerance of uncertainty and meta-worry may assist with the diagnosis and treatment of GAD.

Abstract
AbstractThis study explored how meta-worry and intolerance of uncertainty relate to pathological worry, generalised anxiety, obsessive–compulsive disorder, social phobia, and depression. University students (n = 253)completed a questionnaire battery. A series of regression analyses were conducted. The results indicated that meta-worry was associated with GAD, social phobia, obsessive–compulsive, and depressive symptoms. Intolerance of uncertainty was related to GAD, social phobia, and obsessive–compulsive symptoms, but not depressive symptoms. The importance of meta-worry and intolerance of uncertainty as predictors of pathological worry, GAD, social phobia, obsessive–compulsive and depressive symptoms was also examined. Even though both factors significantly predicted the aforementioned symptoms, meta-worry emerged as a stronger predictor of GAD and obsessive compulsive symptoms than did intolerance of uncertainty. Intolerance of uncertainty, compared with meta-worry, appeared as a stronger predictor of social phobia symptoms. Findings emphasise the importance of addressing meta-worry and/or intolerance of uncertainty not only for the assessment and treatment of generalised anxiety disorder (GAD), but also obsessive–compulsive disorder, social phobia, and depression.

Abstract
The present investigation examined the main and interactive effects of anxiety sensitivity and behavioral distress tolerance, indexed using the breath-holding task, in relation to PTSD symptom severity among trauma-exposed adults. Participants were 88 adults (63.6% women; M(age)=22.9, SD=9.1, range=18-62), recruited from the community, who met DSM-IV-TR PTSD Criterion A for lifetime trauma exposure. Covariates included number of potentially traumatic events, nonclinical panic attack history, and participant sex. Anxiety sensitivity was significantly incrementally associated with PTSD total symptom severity, as well as Avoidance and Hyperarousal symptom severity (p's<.01). Breath-holding duration was not significantly related to PTSD symptom severity (p's>.05). However, breath-holding duration emerged as a significant moderator of the association between anxiety sensitivity and PTSD Avoidance symptom severity, such that lower breath-holding duration exacerbated the effect of heightened anxiety sensitivity with regard to PTSD Avoidance symptom severity.

Abstract
Excessive reassurance-seeking (ERS) is hypothesized to play a key role in emotional disorders but has been studied mostly in relation to depression. Study 1 reports a new measure of reassurance seeking that assessed ERS related to general and evaluative threats in a non-clinical student sample, and its factor structure was further examined in Study 2. In Study 3, the scale, along with other symptom-related measures and an existing measure of depressive ERS, was administered to an undergraduate sample at two different time points, one month apart. Greater ERS was associated with greater symptoms of social anxiety, generalized anxiety disorder, and obsessive-compulsive disorder (OCD), even after controlling for trait anxiety, depression, and intolerance of uncertainty. Among OCD symptoms, only thoughts of harm were uniquely related to ERS, a finding consistent with emerging literature. ERS involving general threats also predicted changes in social anxiety and GAD symptoms one month later. Overall, the findings implicate an important role for ERS across anxiety disorders.

Abstract
Researchers have increasingly suggested that people with anxiety disorders share a common fear that the uncertain future will be catastrophic. Intolerance of uncertainty (IU) - the tendency to consider possible negative events as unacceptable and threatening, irrespective of probabilities - is representative of such fears. A key role has been indicated for IU in several anxiety and mood disorders; however, the present study appears to be the first latent structure examination of IU. Responses were obtained from a large sample (n=977; 65% women) unselected with regard to IU level, comprising anxiety disorder outpatients (i.e., putative taxon members), and community residents (i.e., putative complement class members). MAXEIG, MAMBAC, and L-Mode were performed with indicator sets drawn from the Intolerance of Uncertainty Scale-12. Assessments also included objective Comparison Curve Fit Indices. Results yielded converging evidence that IU symptoms have a dimensional latent structure. Comprehensive findings, implications, and future research directions are discussed.

Abstract
Intolerance of uncertainty (IU) has been identified as a potential maintaining factor for generalised anxiety disorder; however, there is a growing evidence to suggest that IU may contribute to other anxiety and depressive disorders. Moreover, certain components of IU (namely prospective and inhibitory IU) have been shown to be differentially associated with symptoms of emotional disorders. The aim of this study was to determine the extent to which individuals with various anxiety and depressive disorders endorsed IU, firstly as a trait variable (with prospective and inhibitory components) and secondly in reference to regularly occurring, diagnostically relevant situations (situation-specific IU). The degree to which diagnosis predicted IU was examined in a highly comorbid clinical sample (N=218). Regardless of specific diagnoses, the degree of comorbidity emerged as a significant predictor of prospective IU and situation-specific IU. Conversely, specific diagnoses of social phobia, generalised anxiety disorder, depression, and obsessive compulsive disorder were uniquely related to inhibitory IU. These findings suggest that IU is a transdiagnostic construct and have implications for current diagnosis-specific and transdiagnostic theory and clinical practice.

Abstract
Generalized anxiety disorder (GAD) is one of the most common comorbid disorders found in individuals with eating disorders. Despite this, little is known of shared vulnerability factors between the two disorders. The aim of the present study was to examine the four main components of a cognitive model for GAD in the eating disorders. One hundred and sixty-two females took part. Three groups were formed comprising of 19 participants with an eating disorder and GAD, 70 with an eating disorder without GAD and 73 healthy controls. All completed self-report questionnaires that measured eating attitudes, levels of GAD, intolerance of uncertainty, positive beliefs about worry, negative problem orientation, and cognitive avoidance. Participants with an eating disorder and GAD scored the highest on all four components when compared to healthy individuals and on most components when compared to those with an eating disorder. Participants with an eating disorder without GAD scored higher on all components compared to healthy controls. Findings extend our understanding of shared vulnerability factors between the eating disorders and GAD.

Abstract
Anxiety disorders represent a common but often debilitating form of psychopathology in both children and adults. While there is a growing understanding of the etiology and maintenance of these disorders across various research domains, only recently have integrative accounts been proposed. While classical attachment history has been a traditional core construct in psychological models of anxiety, contemporary attachment theory has the potential to integrate neurobiological and behavioral findings within a multidisciplinary developmental framework. The current paper proposes a modern attachment theory-based developmental model grounded in relevant literature from multiple disciplines including social neuroscience, genetics, neuroendocrinology, and the study of family factors involved in the development of anxiety disorders. Recent accounts of stress regulation have highlighted the interplay between stress, anxiety, and activation of the attachment system. This interplay directly affects the development of social-cognitive and mentalizing capacities that are acquired in the interpersonal context of early attachment relationships. Early attachment experiences are conceptualized as the key organizer of a complex interplay between genetic, environmental, and epigenetic contributions to the development of anxiety disorders - a multifactorial etiology resulting from dysfunctional co-regulation of fear and stress states. These risk-conferring processes are characterized by hyperactivation strategies in the face of anxiety. The cumulative allostatic load and subsequent "wear and tear" effects associated with hyperactivation strategies converge on the neural pathways of anxiety and stress. Attachment experiences further influence the development of anxiety as potential moderators of risk factors, differentially impacting on genetic vulnerability and relevant neurobiological pathways. Implications for further research and potential treatments are outlined.

Abstract
A growing trend of neuroimaging, behavioral, and computational research has investigated the topic of outcome uncertainty in decision-making. Although evidence to date indicates that humans are very effective in learning to adapt to uncertain situations, the nature of the specific cognitive processes involved in the adaptation to uncertainty are still a matter of debate. In this article, we reviewed evidence suggesting that cognitive control processes are at the heart of uncertainty in decision-making contexts. Available evidence suggests that: (1) There is a strong conceptual overlap between the constructs of uncertainty and cognitive control; (2) There is a remarkable overlap between the neural networks associated with uncertainty and the brain networks subserving cognitive control; (3) The perception and estimation of uncertainty might play a key role in monitoring processes and the evaluation of the "need for control"; (4) Potential interactions between uncertainty and cognitive control might play a significant role in several affective disorders.

Abstract
OBJECTIVE Intolerance of uncertainty (IU) is an important concept in eating disorders (ED). Cognitive, emotional, and behavioral features of IU amongst individuals with and without ED were investigated. METHOD Participants completed the intolerance of uncertainty scale (IUS) and four versions of a data-gathering task varying in difficulty/uncertainty, and rated their Beads task experience. RESULTS ED groups had significantly higher IUS scores than healthy controls (HC). Bulimia Nervosa (BN) participants requested more cues than HC and Anorexia Nervosa (AN) participants before making decisions. ED groups found the task more distressing than HC participants, with those with BN feeling more uncertain and less confident in their decisions, and those with AN attributing greater importance in making the correct decision. DISCUSSION While both ED groups reported raised IUS scores only BN participants engaged in an elevated evidence requirement data gathering style. Future research might benefit from further exploration of the role of perseverative processes in BN.

Abstract
Intolerance of uncertainty (IU) has been proposed to be an important maintaining factor in several anxiety disorders, including generalized anxiety disorder, obsessive-compulsive disorder, and social phobia. While IU has been shown to predict subjective ratings and decision-making during uncertain/ambiguous situations, few studies have examined whether IU also predicts emotional responding to uncertain threat. The present study examined whether IU predicted aversive responding (startle and subjective ratings) during the anticipation of temporally uncertain shocks. Sixty-nine participants completed three experimental conditions during which they received: no shocks, temporally certain/predictable shocks, and temporally uncertain shocks. Results indicated that IU was negatively associated with startle during the uncertain threat condition in that those with higher IU had a smaller startle response. IU was also only related to startle during the uncertain (and not the certain/predictable) threat condition, suggesting that it was not predictive of general aversive responding, but specific to responses to uncertain aversiveness. Perceived control over anxiety-related events mediated the relation between IU and startle to uncertain threat, such that high IU led to lowered perceived control, which in turn led to a smaller startle response. We discuss several potential explanations for these findings, including the inhibitory qualities of IU. Overall, our results suggest that IU is associated with attenuated aversive responding to uncertain threat.

Abstract
Uncertainty is an omnipresent force in peoples' lives that has been shown to amplify the negative impact of aversive events. This amplified aversiveness, together with the negative attitudes that individuals can have toward uncertainty, suggests that a cue indicating uncertainty about future events might be associated with biased expectancies of negative outcomes or biased contingency estimates, similar to biases that have been observed for traditional fear-relevant cues, such as snakes or spiders. Participants in this study saw three different cues: one that indicated with certainty that an aversive picture would follow, one that indicated with certainty that a neutral picture would follow, and one that indicated uncertainty about whether an aversive or neutral picture would follow. Online self-report data revealed negatively biased expectancies of aversion after uncertain cues. The degree of this online expectancy bias predicted participants' estimates, at the conclusion of the experiment, of the relationship between uncertain cues and aversive pictures. Aversive pictures after the uncertain cue (relative to those after the certain cue) were accompanied by increased skin conductance responses and self-reported negative mood. These findings that uncertainty is accompanied by biased expectancies of aversion and heightened responses to aversion warrant extensions of this research in anxiety disorders, given evidence for intolerance of uncertainty and anticipatory dysfunction in the pathology of such disorders.

Abstract
Approach-avoidance conflict is an important psychological concept that has been used extensively to better understand cognition and emotion. This review focuses on neural systems involved in approach, avoidance, and conflict decision making, and how these systems overlap with implicated neural substrates of anxiety disorders. In particular, the role of amygdala, insula, ventral striatal, and prefrontal regions are discussed with respect to approach and avoidance behaviors. Three specific hypotheses underlying the dysfunction in anxiety disorders are proposed, including: (i) over-representation of avoidance valuation related to limbic overactivation; (ii) under- or over-representation of approach valuation related to attenuated or exaggerated striatal activation respectively; and (iii) insufficient integration and arbitration of approach and avoidance valuations related to attenuated orbitofrontal cortex activation. These dysfunctions can be examined experimentally using versions of existing decision-making paradigms, but may also require new translational and innovative approaches to probe approach-avoidance conflict and related neural systems in anxiety disorders.

Abstract
Evidence is accumulating that intolerance of uncertainty (IU) may be a transdiagnostic maintaining factor across the anxiety disorders and depression. However, psychometric studies of the most commonly used measure of IU have typically used undergraduate students, and the factor structure has been highly inconsistent. Previous studies have also tended to focus on one diagnostic subgroup or related symptom, thereby limiting transdiagnostic comparisons. The first aim of this study was to test the latent structure of a commonly used measure of IU in a treatment-seeking sample with anxiety and depression (n=463). The second aim was to examine psychometric properties of the best fitting solution, including internal reliability, convergent validity, and discriminant validity. Confirmatory factor analysis was used to compare the goodness of fit of five models previously found with undergraduate and community samples. A two-factor solution, comprising of prospective anxiety and inhibitory anxiety, was the best fitting model. The total scale and subscales demonstrated excellent internal reliability. Convergent validity was demonstrated by the scales correlating with symptoms associated with five anxiety disorders and depression, as well as neuroticism, distress and disability. IU explained unique variance in all symptom measures, even after controlling for neuroticism and other symptom measures. Evidence of discriminant validity was also found for each IU subscale. Findings support reliability and validity of the two-factor solution, and are consistent with IU being a transdiagnostic maintaining factor.

Abstract
Anorexia nervosa (AN) is characterized by its similarity to anxiety disorders, especially obsessive-compulsive disorder (OCD). Family-based treatment (FBT) has shown promising initial results for treatment of AN in adolescents, yet the precise mechanisms of action are unknown. We present a theoretical argument and model, suggesting that FBT may work via exposure (and habituation) to food and its consumption. First, we review the evidence for pathological anxiety in AN, and suggest a framework for identifying specific anxious triggers, emotions (fear and worry) and avoidance strategies. Second, we briefly review evidence indicating that cognitive-behavioural therapy (CBT) and specifically exposure in its various forms is most effective for treating anxiety disorders in youth. Third, we consider distinct approaches to exposure therapy based on the pattern of triggers, anxious emotions and avoidance. We conclude that the interventions utilized in FBT share clear similarities to exposure with response prevention, a type of exposure therapy commonly used with OCD, and may work via facilitating habituation to food and eating in one's natural environment. We also highlight how parents facilitate this process in between sessions by effectively coaching their children and facilitating naturalistic exposure to food and related triggers. Options for future research are considered.

Abstract
The present investigation examined the incremental associations between distress tolerance, or the perceived capacity to tolerate emotional distress, and global posttraumatic stress symptom severity as well as symptom cluster severity, beyond the variance accounted for by number of trauma exposure types and negative affectivity. The sample consisted of 140 adults (72 women; M(age)=25.9, SD=11.1) who endorsed exposure to traumatic life events, as defined by posttraumatic stress disorder diagnostic criterion A (American Psychiatric Association 2000). Participants did not meet diagnostic criteria for current axis I psychopathology. Distress tolerance demonstrated significant incremental associations with global posttraumatic stress symptom severity (p<.01) as well as re-experiencing (p<.05), avoidance (p=.05), and hyperarousal (p<.001) symptom cluster severity. Given the cross-sectional study design, causation cannot be inferred. Theoretical implications and future directions for better understanding associations between distress tolerance and posttraumatic stress are discussed.

Abstract
Posttraumatic stress disorder (PTSD) and social anxiety disorder (SAD) are frequently comorbid among veteran and community samples. Several studies have demonstrated significant comorbidity between trauma, PTSD, and social anxiety (SA), and a growing number of studies have explored the nature of this association. Although a diagnosis of either PTSD or SAD alone can result in significant impairment in social and occupational functioning, these difficulties are often magnified in persons suffering from both disorders. This review describes the current state-of-the-art regarding the co-occurrence of trauma, PTSD, and SA. First, we provide an overview of empirical data on the prevalence of co-occurring trauma, PTSD, and SAD. Second, we describe possible explanatory models of the co-occurrence, with a specific focus on the shared vulnerability model. Third, we review the available empirical data addressing the postulates of this model, including both genetic and psychological vulnerabilities. Fourth, we describe additional factors-guilt, shame, and depressive symptoms-that may help to explain the co-occurrence of PTSD and SA. A better understanding of this complex relationship will improve the efficacy of treatment for individuals suffering from both disorders. We conclude with key areas for future research.

Abstract
The present study investigates intolerance of uncertainty and metacognitions in individuals with problematic eating attitudes (PEA) and individuals with normal eating attitudes (NEA). It was hypothesised that individuals with PEA will show higher levels of intolerance of uncertainty and metacognitions compared to individuals with NEA, and that the two variables would be positively associated. A non-clinical sample of 116 UK-based university students completed the Eating Attitudes Test (EAT-26), Metacognitions Questionnaire (MCQ-30) and Intolerance of Uncertainty Scale (IUS). Twenty-seven participants formed the PEA group and 89 the NEA group. Results overall supported the hypotheses, participants with PEA scored significantly higher on three of the five metacognition factors, total metacognition score and intolerance of uncertainty compared to participants with NEA. Positive correlations were also found between intolerance of uncertainty and metacognitions. Findings point towards further examining intolerance of uncertainty and metacognitions in the field of eating disorders. Changing metacognitions and targeting high levels of intolerance of uncertainty could contribute to better treatment outcome for individuals with eating disorders.

Abstract
The current study examined Intolerance of Uncertainty (IU)-the tendency to react negatively to situations that are uncertain-in psychological problems among adolescents. Using data from 191 adolescents, aged 14 to 18, we examined (a) the dimensionality of IU as tapped by the Intolerance of Uncertainty Scale short-form (IUS-12), (b) the relationship of IU with worry, social anxiety, and depression, (c) the specificity of IU to these variables, and (d) the role of IU as a mediator of the linkages between negative affectivity (NA) and worry, social anxiety, and depression. Results showed that the IUS-12 encompassed 2 components of IU, named Prospective Anxiety and Inhibitory Anxiety. Furthermore, IU was specifically related with worry and social anxiety, but not depression, when controlling the shared variance between these variables and NA, age, and gender. Finally, IU and its 2 components were found to mediate the linkages of NA with worry and social anxiety.

Abstract
OBJECTIVE The authors examined the association between social anxiety and drinking game (DG) involvement as well as the moderating role of social anxiety-relevant alcohol outcome expectancies (AOE) in social anxiety and DG involvement among college students. PARTICIPANTS Participants were 715 students (74.8% women, Mage = 19.46, SD = 1.22) from 8 US colleges. METHODS Data were collected via self-report survey from Fall 2005 to Spring 2007. RESULTS Tension Reduction and Liquid Courage AOE moderated the association between social anxiety and DG participation. Tension Reduction AOE and DG participation were positively related among those with high social anxiety, but were associated negatively for those with low social anxiety. Liquid Courage AOE were associated with increased DG participation for those with low social anxiety, but not for those with high social anxiety. CONCLUSIONS Findings suggest that social anxiety acts as a protective or a risk factor for DG participation among college students, depending upon AOE.

Abstract
Interest in the role of intolerance of uncertainty (IU) - the tendency for a person to consider the possibility of a negative event occurring as unacceptable and threatening irrespective of the probability of its occurrence - in anxiety disorders has been increasing in recent research. IU has been implicated as an important construct associated with generalized anxiety disorder (GAD); however, a growing body of research suggests that levels of IU are also high among individuals with other anxiety disorders. Despite the increasing interest, few studies have examined the relationship between IU and social anxiety (SA). The purpose of the present investigation was to further investigate the relationship between IU and SA. Participants included 286 community members (71% women) from Canada who completed measures of IU, SA, anxiety sensitivity, and fear of negative evaluation (FNE). Regression analyses revealed that the inhibitory anxiety dimension of IU, the fear of socially observable anxiety symptoms dimension of anxiety sensitivity, and the FNE were consistently significant predictors of SA symptoms. Unexpectedly, IU and FNE were often comparable predictors of SA variance. Moreover, participants with SA symptoms consistent with SAD exhibited levels of IU comparable to those reported by participants with worry symptoms consistent with GAD. Comprehensive findings, implications, and directions for future research are discussed.

Abstract
Anxiety is a commonly experienced subjective state that can have both adaptive and maladaptive properties. Clinical disorders of anxiety are likewise also common, and range widely in their symptomatology and consequences for the individual. Cognitive neuroscience has provided an increasingly sophisticated understanding of the processes underlying normal human emotion, and its disruption or dysregulation in clinical anxiety disorders. In this chapter, I review functional neuroimaging studies of emotion in healthy and anxiety-disordered populations. A limbic-medial prefrontal circuit is emphasized and an information processing model is proposed for the processing of negative emotion. Data on negative emotion processing in a variety of anxiety disorders are presented and integrated within an understanding of the functions of elements within the limbic-medial prefrontal circuit. These data suggest that anxiety disorders may be usefully conceptualized as differentially affecting emotional reactivity and regulatory processes--functions that involve different neurobiological mechanisms. While the neural bases of several anxiety disorders are increasingly better understood, advances have lagged significantly behind in others. Nonetheless, the conceptual framework provided by convergent findings in studies of emotional processing in normative and anxiety-disordered populations promises to yield continued insights and nuances, and will likely provide useful information in the search for etiology and novel treatments.
