RESUMO
BACKGROUND: Anxiety sensitivity (AS) and disgust sensitivity (DS) are transdiagnostic vulnerability factors for anxiety. Both correlate with blood-injection-injury (BII) phobia symptoms in several studies; however, there is ambiguity about their relative contributions, and studies investigating this have relied on unselected samples. Furthermore, although DS reliably predicts BII in studies that do not account for AS, this may be limited to domain-specific DS rather than DS more broadly. AIMS: The aims of this study were to examine AS and DS as separate and simultaneous predictors of BII fears in a sample with a wide range of BII symptoms, and with attention to the specificity of DS to BII-relevant domains. METHOD: Fifty-three participants who scored above a clinical threshold on a validated measure of dental anxiety, and who represented a wide range of BII severity, completed measures of AS, DS and BII symptoms. RESULTS: AS and DS were moderately to strongly correlated with BII severity (r = .40 and .47, p = .004 and <.001), and both independently predicted BII severity when entered as simultaneous predictors (ß = .32 and .35, p = .045 and .015). Furthermore, after omitting DS about injections and blood draws, domain-general DS was still moderately correlated with BII severity (r = .33, p = .017). However, domain-general DS did not significantly predict BII severity after accounting for AS (ß = .20, p = .164). CONCLUSIONS: AS and DS both predict BII symptoms, and prospective research is warranted to examine them as potential vulnerability factors.

OBJECTIVES: Findings are inconsistent regarding the relationship between worry and anxious arousal (AA). Effortful control (EC) capacity may explain these inconsistent findings, such that only high worriers with higher EC are able to suppress autonomic arousal through worrying. The current study investigated these main and interactive effects of worry and EC on AA as well as depression. METHODS: Participants (N = 1210, 779 females) were recruited from Amazon's Mechanical Turk website and completed self-report measures assessing worry, EC, AA, depression, and negative affect intensity. RESULTS: Regression models revealed that EC moderated the relationship between worry and AA, with individuals lower in EC demonstrating a stronger positive relationship between worry and AA. EC also moderated the relationship between worry and depression, with individuals lower in EC demonstrating a stronger positive relationship between worry and depression. Results remained the same when controlling for age, gender, and negative affect intensity. CONCLUSIONS: Results support the idea that low EC may help to explain a range of comorbid psychiatric symptoms. PRACTITIONER POINTS: Individuals low in effortful control demonstrate a stronger association between worry and anxious arousal, as well as between worry and depression Those low in effortful control may be especially vulnerable to comorbid worry and depression High worriers who are high in effortful control may be motivated to continue worrying due to their ability to reduce anxious arousal during worry.

Background: Despite widespread availability of COVID vaccines and evidence of their efficacy, vaccine hesitancy remains prevalent. Several studies have examined the relationship between disgust sensitivity and vaccine hesitancy. Although results from studies using data collected prior to the COVID pandemic indicate that higher disgust sensitivity is related to greater vaccine hesitancy, results from studies using data collected during the COVID pandemic are equivocal. The present study examined whether perceived risk of contracting COVID moderated the relationship between disgust sensitivity and vaccine hesitancy. Methods: Participants (n = 152) completed self-report measures of disgust sensitivity, perceived risk of contracting COVID, and COVID vaccine hesitancy (defined as both vaccine confidence and vaccine complacency). Results: Perceived risk of contracting COVID significantly moderated the relationship between disgust sensitivity and vaccine complacency, with the association strengthened at low levels of perceived risk. Perceived risk of contracting COVID also marginally moderated the relationship between disgust sensitivity and vaccine confidence, with the association strengthened at low and average levels of perceived risk. Conclusions: Results suggest that individuals with elevated disgust sensitivity who also report low levels of perceived risk of contracting COVID are more likely to express vaccine hesitancy. Implications of these findings are discussed. Supplementary Information: The online version contains supplementary material available at 10.1007/s10608-023-10391-8.
RESUMO
Background and Objectives: Global pandemics, including COVID-19, have a significant effect on mental health, and this may be especially true for individuals with health anxiety. Although health anxiety is related to both pandemic-related fears and perceptions of health risks, there is a paucity of research on individual difference variables that might exert an influence on these relationships. The present study examined intolerance of uncertainty (IU) as a potential moderator of the relationship between health anxiety and COVID-related stress, and the relationship between health anxiety and perceived risk of contracting COVID. Design and Methods: A nationally representative sample of North American adults (N = 204) completed self-report measures of health anxiety, IU, COVID-related stress, and perceived risk of contracting COVID. Results: Prospective IU moderated the positive relationship between health anxiety and COVID-related stress, as the relationship was strengthened at average and higher levels of prospective IU. Neither IU subscale moderated the relationship between health anxiety and perceived risk. Conclusion: These results suggest that individuals with elevated health anxiety and high prospective IU may be at higher risk of experiencing COVID-related stress, illuminating the interplay of risk factors that place anxious populations at an increased risk of experiencing stress during acute health risks.

RESUMO
Since the introduction of generalized anxiety disorder into the diagnostic system for psychiatric conditions, scientists have worked to develop effective treatments for the amelioration of chronic, excessive worry. In addition to traditional cognitive-behavioral therapy, more recent advances have focused on treatments targeting intolerance of uncertainty, meta-cognitions, emotion dysregulation, lack of acceptance of internal experiences, and emotional contrasts. This article reviews these therapeutic approaches and summarizes recent publications relevant to the psychological treatment of worry and generalized anxiety disorder.

OBJECTIVES: We examined the reliability, validity, and factor structure of the posttraumatic stress diorder (PTSD) Checklist-Civilian Version (PCL-C; Blanchard, Jones-Alexander, Buckley, & Forneris, 1996) among unselected undergraduate students. PARTICIPANTS: Participants were 471 undergraduate students at a large university in the Eastern United States and were not preselected based on trauma history or symptom severity. RESULTS: The PCL-C demonstrated good internal consistency and retest reliability. Compared with alternative measures of PTSD, the PCL-C showed favorable patterns of convergent and discriminant validity. In contrast to previous research using samples with known trauma exposure, we found support for both 1-factor and 2-factor models of PTSD symptoms. CONCLUSIONS: Overall, the PCL-C appears to be a valid and reliable measure of PTSD symptoms, even among nonclinical samples, and is superior to some alternative measures of PTSD. The factor structure among nonclinical samples may not reflect each of the PTSD symptom "clusters" (i.e., reexperiencing, avoidance/numbing, and hyperarousal).

Prospective intolerance of uncertainty (IU) involves fear and anxiety in anticipation of future uncertainty and is especially related to worry and generalized anxiety disorder (GAD). Individuals high in IU appraise uncertain situations as threatening and thus may engage in excessive information-seeking behavior to decrease uncertainty. This study aimed to examine the links between prospective IU and information-seeking. Participants (N = 174) high and low in prospective IU completed an ostensible aptitude test (threat stimulus), which was supposedly either excellent (high relevance condition) or poor (low relevance condition) at predicting future outcomes. Thus, the test itself presented an immediate threat, and the awaited test results generated uncertainty. Following the relevance manipulation, participants were given the opportunity to engage in information-seeking behavior by asking questions about the ostensible test and by requesting feedback about the test results. Results indicated that in the high-relevance condition, individuals high and low in IU evidenced similar levels of information-seeking behavior. Conversely, in the low-relevance condition, individuals low in IU evidenced less information-seeking than did individuals high in IU. Furthermore, cognitive appraisals of ambiguous situations were associated with the extent of information-seeking behavior. The implications of these findings for the treatment of GAD are discussed.

Individuals with dental anxiety show biased attentional processing of threat- and dental-related information. Disgust sensitivity and anxiety sensitivity are both associated with dental fears and attentional biases. Whereas disgust sensitivity is generally associated with attentional avoidance (Armstrong et al., 2014), anxiety sensitivity may be associated with attentional engagement (Keogh et al., 2001a). Elucidating the role of these constructs in dental anxiety-relevant attentional biases could inform theoretical models and/or intervention recommendations. Participants (N = 51) with high dental anxiety completed a Posner paradigm to assess attentional biases to dental versus neutral stimuli. We examined whether disgust sensitivity and anxiety sensitivity moderated degree of attentional bias. Results indicated that both disgust sensitivity (mutilation subscale) and anxiety sensitivity (physical concerns subscale) statistically moderated degree of attentional bias at trend level, and in opposite directions. Simple effects analyses further indicated that disgust sensitivity regarding mutilation was associated with less attentional bias toward dental relative to neutral stimuli, potentially indicating attentional avoidance, and remained so when adjusting for anxiety sensitivity. In contrast, simple effects analysis indicated that anxiety sensitivity regarding physical concerns was not associated with magnitude of attentional bias. If replicated, findings highlight the potential role of disgust in dental anxiety.

Sleep health, a crucial component and predictor of physical and mental health, has likely been adversely impacted by the stress and disruption wrought by the COVID-19 pandemic. This brief report sought to assess self-reported sleep quality among sexual minority men across the U.S.A. in the early months of the pandemic. In a cross-sectional online survey of a racially-diverse sample of 477 sexual minority men (mean age of 41.2; range 18-75 years) recruited from popular geo-social networking apps in early May 2020, participants reported on their recent experiences regarding sleep and mental health (anxiety, depression, and pessimistic repetitive future thinking). Almost 75% endorsed some level of restless sleep in the past week, 203 (42.6%) reported worse-than-usual sleep quality since the pandemic, and 77 (16.1%) reported sleeping longer than usual but not feeling better rested. Further, of the 280 reporting worse-than-usual sleep or feeling not rested, almost 85% reported that worry about the pandemic had been contributing to their troubles with falling or staying asleep. Rates of worsened sleep were highest among those whose financial situation had been adversely affected and those not in full-time employment, whereas restless sleep was highest among those in the Northeast region of the U.S.A., which, during the study's timeframe of late April and early May 2020, was the most severely affected by the pandemic. Greater emotional distress was associated with each sleep variable. Addressing and improving sleep health is critical to overall health and requires particular attention during the COVID-19 pandemic.
RESUMO
Previous research has documented the inhibitory effects of worry on cardiovascular reactivity to subsequently presented fear-relevant stimuli. Although theoretical assertions point to the verbal-linguistic (as opposed to imagery-based) nature of worry as the cause of these inhibitory effects, extant research investigating the effects of worrisome thinking on subsequent anxiety-eliciting tasks has not isolated the verbal-linguistic nature of worry as the active ingredient in its suppressive effects on arousal. Furthermore, prior research has not examined the potential effects of worry on maintenance of panic symptoms. In this study, participants high in anxiety sensitivity were asked to engage in verbal worry, imaginal worry, or relaxation prior to each of three repeated presentations of an interoceptive exposure task. Relaxation was associated with lower initial subjective fear that remained low across repeated exposures, and related stable sympathetic arousal (and decreased heart rate) over time. Imagery-based worry was associated with moderate initial subjective fear that was sustained across repeated exposures, and sympathetic arousal (and heart rate) that was likewise stable over time. However, verbal worry was associated with high initial subjective fear that was sustained over time, but sympathetic arousal (and heart rate) that decreased across repeated exposures. Thus, verbal worry was uniquely associated with a lack of synchronous response systems and maintenance of anxious meaning over time. Theoretical and clinical implications are discussed.

BACKGROUND AND OBJECTIVES: Research indicates that greater variability in affect and emotion over time is associated with depression and anxiety. However, it remains unclear whether individuals with generalized anxiety disorder (GAD) experience greater affect variability due to individual differences or differences in the stimuli they encounter. The current study investigated whether individuals with analogue GAD demonstrate greater affect variability in response to a standardized set of stimuli. METHODS: Participants were 134 (95 female) undergraduate participants with analogue GAD (endorsing DSM-IV criteria A, B, C, and E on the GAD-Q-IV; n = 66) or with no symptoms of GAD (n = 68). Participants reported affective reactions (positive affect, negative affect, affective arousal, and affective dominance) to each of nine sets of standardized images varying in valence (positive, neutral, or negative) and arousal (low, medium, or high). RESULTS: In a logistic regression model controlling for baseline measurements, higher variability of affective arousal across the nine sets of images uniquely predicted analogue GAD status, whereas variability in positive affect, negative affect, and affective dominance did not. Additional analyses revealed that lower mean affective arousal also uniquely predicted analogue GAD. LIMITATIONS: Limitations include using self-report measures to determine analogue GAD status; using a short laboratory session for the assessment of affect variability; and potential repeated testing effects. CONCLUSIONS: These findings suggest that individuals with GAD symptoms experience higher levels of affective arousal variability, even when the stimuli presented are held constant. Assessing variability in affective arousal may be helpful in both conceptualizing and treating individuals with GAD symptoms.

Dental anxiety is common and associated with negative outcomes. According to information-processing models, anxiety is maintained by maladaptive patterns of processing threatening information. Furthermore, attention training interventions can reduce anxiety in one session. Fifty-three individuals with high levels of dental anxiety completed a Posner reaction-time task. Participants were randomized to attention training or control using a dot-probe task, and then attentional bias was remeasured using another Posner task. Participants then completed a script-driven imaginal exposure task. Results indicated that individuals high in dental anxiety exhibit threat-relevant attentional bias. There was mixed evidence about the efficacy of attention training. On the one hand, training did not eliminate attentional bias and training condition did not predict distress during the imagery task. On the other hand, cue dependency scores in the control group were higher for dental than neutral cues, but did not differ in the training group. In addition, cue dependency scores for both dental and neutral cues predicted subjective anxiety in anticipation of the imagery task. The mixed results of training are considered in terms of the possibility that it enhanced attentional control, rather than reducing bias.
RESUMO
The avoidance theory of worry (Borkovec, Alcaine, & Behar, 2004) posits that the verbal-linguistic (versus imagery-based) nature of worry elicits abstract (versus concrete) processing, which inhibits affective responding and generates a host of negative consequences. Although suppression of worrisome thinking is maladaptive (Purdon, 1999), expression of worry using vivid imagery may increase concreteness of worrisome thinking and facilitate more adaptive emotional responding. The present study examined whether the valence, content, and expression of mentation impacts concreteness of thought. Participants (N = 62) were randomly assigned to verbalize their thoughts while engaging in either verbal-linguistic- or imagery-based mentation about both worrisome and neutral topics. Participants were also randomly assigned to engage in a 5-min period of suppressing or expressing the target stimuli before engaging in 5-min of freely expressing the targets. Verbalizations of mental content were coded for level of abstractness/concreteness. For neutral stimuli, imagery-based mentation led to greater concreteness than did verbal-linguistic mentation; however, for worrisome stimuli, imagery-based mentation did not enhance concreteness. In addition, for neutral (but not worrisome) stimuli, an initial period of suppression was associated with increased concreteness during subsequent expression. Imagery-based mentation about worrisome stimuli may not enhance concreteness; moreover, unlike suppression of neutral stimuli, suppression of worrisome stimuli may maintain, rather than ameliorate, abstractness of thought.

The intolerance of uncertainty model of worry posits that individuals worry as a means to cope with the discomfort they feel when outcomes are uncertain, but few experimental studies have investigated the causal relationships between intolerance of uncertainty, situational uncertainty, and state worry. Furthermore, existing studies have failed to control for the likelihood of future negative events occurring, introducing an important rival hypothesis to explain past findings. In the present study, we examined how individuals with high and low trait intolerance of uncertainty differ in their behavioral, cognitive, and emotional reactions to situational uncertainty about an upcoming negative event (watching emotionally upsetting film clips), holding constant the likelihood of that negative event taking place. We found that although individuals high in trait prospective intolerance of uncertainty reported a higher degree of belief that being provided with detailed information about the upcoming stressor would make them feel more at ease, they did not experience an actual decrease in distress or state worry upon being provided with more information, during anticipation of the film clips, or during the film clips themselves. Our results suggest that heightened distress regarding negative events may be more central than intolerance of uncertainty to the maintenance of worry.

BACKGROUND: Exercise interventions repeatedly have been shown to be efficacious for the treatment of depression, and initial studies indicate similar efficacy for the treatment of anxiety conditions. To further study the potential beneficial role of prescriptive exercise for anxiety-related conditions, we examined the role of exercise in reducing fears of anxiety-related sensations (anxiety sensitivity). METHODS: We randomly assigned 60 participants with elevated levels of anxiety sensitivity to a 2-week exercise intervention, a 2-week exercise plus cognitive restructuring intervention, or a waitlist control condition. Assessment of outcome was completed at pretreatment, midtreatment, 1-week posttreatment, and 3-week follow-up. RESULTS: We found that both exercise conditions led to clinically significant changes in anxiety sensitivity that were superior to the waitlist condition, representing a large controlled effect size (d=2.15). Adding a cognitive component did not facilitate the effects of the exercise intervention. Consistent with hypotheses, changes in anxiety sensitivity mediated the beneficial effects of exercise on anxious and depressed mood. CONCLUSIONS: We discuss these findings in terms of the potential role of exercise as an additional psychosocial intervention for conditions such as panic disorder, where anxiety sensitivity is a prominent component of pathology.

OBJECTIVES: Methadone is the most frequently prescribed medication for the treatment of opioid dependence in the U.S., and questions relating to appropriate dosing of methadone remain an important issue. Given accumulating evidence suggesting an elevated prevalence of personality pathology in opioid dependent populations, as well as evidence of an association between Cluster B characteristics and substance use severity, we hypothesized that patients with such pathology would have elevated methadone dose prescriptions. METHODS: Participants were 54 opioid dependent individuals recruited from a methadone maintenance clinic. RESULTS: RESULTS indicated that participants with symptoms consistent with Cluster B pathology had a significantly higher mean prescribed methadone dose relative to participants without Cluster B pathology. CONCLUSION: The presence of personality traits appears to influence methadone maintenance. Implications of this finding are discussed.

Cognitive bias modification for interpretation (CBM-I) is a promising treatment modality for social anxiety disorder, but effect sizes are relatively small across investigations (Hallion & Ruscio, 2011). Additionally, the extent to which CBM-I impacts other cognitive, emotional, and behavioral outcomes is unclear. This study investigated whether two empirically supported treatment components for anxiety disorders, imaginal exposure (IE) and relaxation, augment the effects of CBM-I and increase the extent to which the effects of CBM-I generalize to behavioral and affective outcomes. We randomly assigned 111 undergraduate students with social anxiety to undergo IE, relaxation, or neutral thinking prior to CBM-I, then measured their interpretation biases, as well as their speaking time, anxiety, and subjective evaluations of performance during a speech task. Results indicated that individuals who received IE prior to CBM-I evidenced more adaptive interpretation biases and less behavioral avoidance during the speech task than did individuals who engaged in relaxation or neutral thinking. However, they did not report differential anxiety, habituation, or evaluations of their performance on the speech task. These findings suggest that the combination of CBM-I with adjunct components that target behavioral, rather than cognitive, mechanisms can facilitate transfer of the effects of CBM-I to reducing behavioral avoidance.

Worry is associated with inflexibility in cognitive, emotional, and physiological functioning. In addition, worry's negative valence and abstract level of construal are rigid characteristics that contribute to its nonadaptive consequences. Relaxation and cognitive therapy aim to increase flexibility in chronic worriers, and may have greater efficacy when administered in combination. We examined the extent to which relaxation enhances and/or worry inhibits cognitive flexibility during a cognitive restructuring exercise in which participants generated alternative predictions for their worries. Participants ( n = 189) were randomly assigned to engage in relaxation, worry, or neutral thinking prior to cognitive restructuring. We measured the number and perceived likelihood of alternative predictions generated by participants, and coded those alternative predictions for their degree of positive valence, negative valence, and level of construal (abstractness to concreteness). Worry and relaxation did not lead to different numbers or perceived likelihood of alternative predictions. However, compared with participants with minimal symptoms of generalized anxiety disorder (GAD), those with elevated symptoms of GAD who engaged in prior worry generated alternative predictions characterized by greater negative valence and more abstractness (i.e., less concreteness). We also found that greater negative valence of alternative predictions was associated with more abstractness, whereas greater positive valence of alternative predictions was associated with more concreteness. These findings suggest that after engaging in worry, individuals with GAD may be less able to flexibly shift from the use of nonadaptive characteristics (negative valence, abstractness) associated with feared outcomes to the use of more adaptive characteristics (positive valence, concreteness) when considering alternative predictions.

BACKGROUND AND OBJECTIVES: Worry and anticipatory processing are forms of repetitive negative thinking (RNT) that are associated with maladaptive characteristics and negative consequences. One key maladaptive characteristic of worry is its abstract nature (Goldwin & Behar, 2012; Stöber & Borkovec, 2002). Several investigations have relied on inductions of worry that are social-evaluative in nature, which precludes distinctions between worry and RNT about social-evaluative situations. The present study examined similarities and distinctions between worry and anticipatory processing on potentially important maladaptive characteristics. METHODS: Participants (N = 279) engaged in idiographic periods of uninstructed mentation, worry, and anticipatory processing and provided thought samples during each minute of each induction. Thought samples were assessed for concreteness, degree of verbal-linguistic activity, and degree of imagery-based activity. RESULTS: Both worry and anticipatory processing were characterized by reduced concreteness, increased abstraction of thought over time, and a predominance of verbal-linguistic activity. However, worry was more abstract, more verbal-linguistic, and less imagery-based relative to anticipatory processing. Finally, worry demonstrated reductions in verbal-linguistic activity over time, whereas anticipatory processing demonstrated reductions in imagery-based activity over time. LIMITATIONS: Worry was limited to non-social topics to distinguish worry from anticipatory processing, and may not represent worry that is social in nature. Generalizability may also be limited by use of an undergraduate sample. CONCLUSIONS: Results from the present study provide support for Stöber's theory regarding the reduced concreteness of worry, and suggest that although worry and anticipatory processing share some features, they also contain characteristics unique to each process.

This study examined the Panic Disorder Self-Report (PDSR), a new self-report diagnostic measure of panic disorder based on the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 1994). PDSR diagnoses were compared with structured interview diagnoses of individuals with generalized anxiety disorder, social phobia, and panic disorder and nonanxious controls. Receiver operating characteristic analyses revealed that the PDSR showed 100% specificity and 89% sensitivity. The PDSR also demonstrated retest reliability, convergent and discriminant validity, and kappa agreement of .93 with a structured interview. Finally, the PDSR demonstrated clinical validity. Students who were identified as having panic disorder using the PDSR did not have significantly different scores on the Panic Disorder Severity Scale--Self-Report form (P. R. Houck, D. A. Speigel, M. K. Shear, & P. Rucci, 2002) than a panic disordered community sample. However, both groups had significantly higher scores than students identified as not meeting criteria for panic disorder.
