Anxiety Sensitivity Amelioration Training (ASAT): a longitudinal primary prevention program targeting cognitive vulnerability

Role of interoceptive fear and maladaptive attention and behaviors in the escalation of psychopathology-a network analysis

The complex interplay of fear, attention, and behavior toward bodily sensations with psychopathological symptoms and how they mutually influence and potentially reinforce one another remains to be fully elucidated. In this study, we used a network analytical approach to unravel these complex interactions. Specifically, we aimed to identify central symptoms and etiologically relevant factors that might be associated with anxiety and depressive core symptoms. To this end, the following clusters were assessed in 791 adults: interoceptive fear, interoceptive attention, maladaptive behaviors related to bodily sensations, and core symptoms of anxiety and depression. This network was modeled using a Gaussian Graphical Model. Central variables (nodes) were identified using centrality indices and bridge analysis. Self-examination and attention to bodily sensations emerged as central nodes. Moreover, time spent paying attention to bodily sensations, fear of anxiety-related sensations, and self-examination were identified as central bridge nodes, that is, central nodes connecting psychopathologically relevant symptom clusters. The present study indicates that fear of bodily sensations, the amount of attention and time spent focusing on somatic sensations, and self-examination are central factors. The findings suggest potential targets for future longitudinal studies on the impact of these factors for the escalation of anxiety and depressive symptoms.

Brief observable anxiety sensitivity treatment: intervention development and a pilot randomized-controlled acceptability and feasibility trial to evaluate a brief intervention for anxiety sensitivity social concerns

Social anxiety disorder is one of the most prevalent anxiety disorders. There is a need to develop brief, virtual, single-session interventions targeting constructs associated with social anxiety, such as anxiety sensitivity social concerns (ASSC). ASSC is the maladaptive belief about consequences arising from observable symptoms of anxious arousal. This study was designed to evaluate the initial acceptability and feasibility of a brief ASSC reduction program (Brief Observable Anxiety Sensitivity Treatment [BOAST]) which included a single clinician-led intervention session followed by a two-week ecological momentary intervention (EMI), delivered via mobile app. Participants (N = 36) were adults with elevated ASSC who were randomly assigned to receive BOAST (n = 19) or a waitlist control (n = 17). The trial was prospectively registered at clinicaltrials.gov (NCT04859790). Results supported the acceptability of BOAST with mixed findings for feasibility. Feasibility metrics for the EMI component were below pre-defined thresholds; however, there was evidence that homework completion was associated with symptom reduction. Preliminary efficacy metrics indicated that participants in the BOAST condition had large reductions in ASSC and one measure of social anxiety at 1-month follow-up. This study provides preliminary support for the acceptability of BOAST and elucidates avenues for future clinical and research efforts.

Personalized feedback intervention for individuals with low distress tolerance who smoke cigarettes: A randomized controlled trial of a digital intervention

INTRODUCTION

Cigarette smoking remains the leading preventable cause of death and disability in the United States and frequently co-occurs with anxiety and depressive symptoms. A novel and integrative, theory-driven approach to address the heterogeneity of mood-related symptoms associated with cigarette use is to focus on transdiagnostic processes, such as distress tolerance, that underpin both mood-related symptoms and smoking behavior. The current study sought to develop and examine the feasibility, acceptability, and initial efficacy of a digitally delivered integrated personalized feedback intervention (PFI) that addresses smoking-distress tolerance relations.

METHODS

Participants included 121 adults (71.1 % male; Mage = 29.33 years, SD = 7.52) who smoked cigarettes daily and reported low distress tolerance. The study randomized participants to the Active PFI (feedback on distress tolerance and smoking) or the Control PFI (feedback on smoking only).

RESULTS

Results indicated feasibility and acceptability demonstrated by the ability to retain participants through the 1-month follow-up (98.2 % retention rate) and positive feedback from participants, including satisfaction regarding the Active PFI. The Active PFI (vs. Control PFI) was also a statistically significant predictor of change in motivation and intention to quit smoking and willingness to use adaptive coping strategies from baseline to 1-month follow-up.

CONCLUSIONS

For individuals with low distress tolerance who smoke cigarettes, this study's findings suggest that the current intervention may be a first-step to aid in increasing motivation/intention to quit smoking and willingness to use adaptive coping strategies.

Anxiety sensitivity and social support in veterans with emotional disorders

OBJECTIVE

An understanding of the incremental value of social support in predicting psychopathology above transdiagnostic risk factors could speak to the benefit of leveraging social factors into existing, evidence-based interventions in veterans with emotional disorders. This cross-sectional study aimed to expand our understanding of associations between domains of anxiety sensitivity and facets of psychopathology in veterans with emotional disorders. We also determined whether social support predicted psychopathology above anxiety sensitivity domains and combat exposure and explored these relationships with a path model.

METHODS

One hundred and fifty-six treatment-seeking veterans with emotional disorders completed diagnostic interviews and assessments of demographics, social support, symptom measures (e.g., PTSD, depression, anxiety, and stress), and transdiagnostic risk factors (i.e., anxiety sensitivity). After data screening, 150 were included in regressions.

RESULTS

Using regression analyses with cross-sectional data, cognitive anxiety sensitivity concerns predicted PTSD and depression above combat exposure. Cognitive and physical concerns predicted anxiety, and cognitive and social concerns predicted stress. Above combat exposure and anxiety sensitivity, social support predicted PTSD and depression.

CONCLUSION

Focusing on social support in tandem with transdiagnostic mechanisms in clinical samples is critical. These findings inform transdiagnostic interventions and recommendations related to incorporation of assessment of transdiagnostic factors in clinical contexts.

Can psychological interventions prevent or reduce risk for perinatal anxiety disorders? A systematic review and meta-analysis

OBJECTIVE

Little is known about the extent to which interventions can prevent perinatal anxiety disorders. We conducted a systematic review and meta-analysis to examine whether interventions can decrease the onset and symptoms of perinatal anxiety among individuals without an anxiety disorder diagnosis.

METHOD

We conducted a comprehensive literature search across five databases related to key concepts: (1) anxiety disorders/anxiety symptom severity (2) perinatal (3) interventions (4) prevention. We included studies that examined a perinatal population without an anxiety disorder diagnosis, included a comparator group, and assessed perinatal anxiety. We included interventions focused on perinatal anxiety as well as interventions to prevent perinatal depression or influence related outcomes (e.g., physical activity).

RESULTS

Thirty-six studies were included. No study assessing the incidence of perinatal anxiety disorder (n = 4) found a significant effect of an intervention. Among studies assessing anxiety symptom severity and included in the quantitative analysis (n = 30), a meta-analysis suggested a small standardized mean difference of -0.31 (95% CI [-0.46, -0.16], p < .001) for anxiety at post intervention, favoring the intervention group. Both mindfulness (n = 6), and cognitive behavioral therapy approaches (n = 10) were effective.

CONCLUSIONS

Interventions developed for perinatal anxiety were more effective than interventions to prevent perinatal depression. Psychological interventions show promise for reducing perinatal anxiety symptom severity, though interventions specifically targeting anxiety are needed.

The Relationship Between Family Accommodation and Anxiety Sensitivity in Obsessive-Compulsive Disorder

Objective Anxiety sensitivity (AS) is an issue that has gained importance in obsessive-compulsive disorder (OCD) in recent years. Family accommodation (FA) is the participation of family members in compulsions and rituals. The objectives of this study were to (1) investigate the relationship between FA and AS in OCD and (2) determine the frequency and types of FA in a Turkish OCD sample. Methods This cross-sectional study was conducted with 81 OCD patients. The Yale-Brown Obsession Compulsion Scale (YBOCS), Family Accommodation Scale-Patient Form (FAS-PF), Anxiety Sensitivity Index-3 (ASI-3), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI) were administered to the patients. Results Family accommodation was extremely prevalent among family members of OCD patients. There were significant relationships between FA and ASI-3 total, ASI-3 cognitive subscale, ASI-3 psychical subscale, YBOCS, and BAI scores. In addition, ASI-3 total, ASI-3 cognitive subscale, and ASI-3 psychical subscale were significant predictors for family accommodation above and beyond the OCD severity. Conclusions The present study identified a significant association between anxiety sensitivity and family accommodation in OCD. Anxiety sensitivity is a relievable psychological trait. Alleviating anxiety sensitivity can decrease accommodating behaviors and may be beneficial in OCD treatment. Anxiety sensitivity may be a novel potential treatment target for OCD.

Evaluating the long-term (Three Year) durability of brief interventions targeting risk factors for psychopathology

Despite their brevity, prior work indicates that computer-based interventions can substantially impact risk factors for psychopathology including anxiety sensitivity (AS), thwarted belongingness (TB), and perceived burdensomeness (PB). However, very few studies have assessed the long-term (> 1 year) effects of these interventions. The primary aim of the current study was to evaluate post-hoc, the long-term (3 year) durability of brief interventions targeting risk factors for anxiety and mood psychopathology using data from a pre-registered randomized clinical trial. Moreover, we were interested in evaluating whether mitigation in these risk factors mediated long-term symptom change. A sample determined to be at-risk for anxiety and mood pathology based on elevations on several risk factors (N = 303) was randomly assigned to one of four experimental conditions focused on: (1) reducing TB and PB; (2) reducing AS, (3) reducing TB,PB, and AS; or (4) a repeated contact control condition. Participants were assessed at post-intervention, one, three, six, 12, and 36 month follow-ups. Participants in the active treatment conditions showed sustained reductions in AS and PB through long-term follow-up. Mediation analyses suggested that reductions in AS mediated long-term reductions in anxiety and depression symptoms. These findings suggest that brief and scalable risk reduction protocols have long-term durability and efficacy both in terms of reducing risk factors for psychopathology.

A Smartphone-Based Intervention for Anxiety and Depression in Racially and Ethnically Diverse Adults (EASE): Protocol for a Randomized Controlled Trial

BACKGROUND

Clear health disparities have emerged in the rates of COVID-19 exposure, hospitalization, and death among Black, Hispanic, and American Indian (BHAI) individuals, relative to non-Hispanic White (NHW) individuals. BHAI populations have been disproportionately affected by lower behavioral health access and heightened negative mental health outcomes during the pandemic.

OBJECTIVE

This project directly addresses health disparities in access to behavioral health care during the COVID-19 pandemic among BHAI populations via an adaptation of the established, initially validated, low-cost, mobile app Easing Anxiety Sensitivity for Everyone (EASE) among individuals with symptoms of elevated anxiety or depression or both.

METHODS

The EASE trial is a 2-arm, prospective, randomized, blinded-assessor study with intention-to-treat analysis. Participants (N=800; n=200, 25%, Black; n=200, 25%, Hispanic; n=200, 25%, American Indian; and n=200, 25%, NHW) are randomized to receive either EASE or an active comparison condition for anxiety and depression. Participants compete an online prescreener, an enrollment call to provide informed consent, a baseline survey, a 6-month intervention period, and 3- and 6-month postbaseline assessments. Select participants also complete a 3- and 6-month postbaseline qualitative interview via phone or an online platform (eg, Zoom). Participants complete 2 scheduled daily ecological momentary assessments (EMAs) during the 6-month study period. These twice-daily EMAs guide a just-in-time approach to immediate, personalized behavioral health care.

RESULTS

Outcomes include reductions in anxiety and depressive symptoms and functional impairment at 3 and 6 months postrandomization. We also will examine putative mechanisms (eg, anxiety sensitivity [AS] and COVID-19-specific stress and fear) of the intervention effects. Further, as treatment effects may differ across sociocultural factors, perceived discrimination, social support, and socioeconomic status (SES) will be evaluated as potential moderators of treatment effects on the primary outcomes. Process evaluation using data collected during the study, as well as individual interviews with participants, will complement quantitative data.

CONCLUSIONS

Data from this efficacy trial will determine whether EASE successfully improves symptoms of anxiety and depression and whether these improvements outperform an active comparison control app. If successful, findings from this study have the potential to decrease anxiety and depression symptoms among vulnerable populations determined to be most at risk of exacerbated, long-lasting negative health sequelae. Data from this study may be used to support an implementation and dissemination trial of EASE within real-world behavioral health and social service settings.

Relations Between Anxiety Sensitivity and Attachment in Outpatients With Borderline Personality Disorder

Borderline personality disorder (BPD) is characterized by dysregulated emotion, interpersonal relationships, and impulsivity, and is putatively linked to a known transdiagnostic risk factor, anxiety sensitivity (AS). AS is a dispositional fear of the physical, cognitive, and/or social consequences of arousal-related somatic sensations. Gratz et al. (2008) demonstrated significantly higher AS in outpatients with BPD and a predictive value of AS over and above emotion dysregulation and impulsivity. The present study sought to extend these findings with a larger sample of outpatients with BPD by investigating predictive value of AS dimensions; relations between AS and attachment style; and impact of BPD treatment on AS. Participants completed measures at three time points: pretreatment and 6 and 12 months posttreatment. AS social was the best predictor; attachment anxiety correlated positively with AS global and AS physical. AS levels significantly decreased from pretreatment to 6 months posttreatment. Clinical implications discussed include targeting AS in BPD treatment.

Interoceptive anxiety-related processes: Importance for understanding COVID-19 and future pandemic mental health and addictive behaviors and their comorbidity

The COVID-19 pandemic is associated with an increased prevalence of mental health problems and addictive behaviors. There is a growing theoretical and empirical evidence that individual differences in interoceptive anxiety-related processes are a one set of vulnerability factors that are important in understanding the impact of pandemic-related mental health problems and addictive behavior. However, there has not been a comprehensive effort to explore this rapidly growing body of research and its implications for public health. In this paper, we discuss why interoceptive anxiety-related processes are relevant to understanding mental health and addictive behaviors during the COVID-19 pandemic. We then provide a narrative review of the available COVID-19 literature linking interoceptive fear and anxiety-related processes (e.g., anxiety sensitivity, health anxiety, and COVID-19 anxiety, fear, and worry) to mental health and addictive behaviors. We then propose a novel transdiagnostic theoretical model that highlights the role of interoceptive anxiety-related processes in mental health and addictive behavior in the context of the present and future pandemics. In the final section, we utilize this conceptualization to underscore clinical implications and provide guidance for future research initiatives in the management of COVID-19 mental health and addictive behaviors and inform the public health field for future pandemics.

Changes in Internalizing Symptoms and Anxiety Sensitivity Among College Students During the COVID-19 Pandemic

The early months of the COVID-19 pandemic saw significant increases in symptoms of anxiety and depression, particularly among college students. However, research has not examined how internalizing symptoms in this population have changed as the pandemic has continued into its second year. Further, there has yet to be an examination of potential changes in transdiagnostic vulnerability factors. Therefore, the purpose of the current repeated cross-sectional study was to examine differences by term in undergraduates’ symptoms of depression, anxiety, worry, social anxiety, and anxiety sensitivity in the Spring 2020 (n = 251), Fall 2020 (n = 427), and Spring 2021 (n = 256) semesters. Results indicated that there were significant increases in depression, anxiety, worry, and anxiety sensitivity from Spring 2020 to Fall 2020 that were maintained through the Spring 2021 semester, and levels of social anxiety were significantly higher in Spring 2021 compared to Spring 2020. These findings suggest that the mental health impacts of the COVID-19 pandemic on college students have continued beyond the initial months, and colleges and universities will need to develop comprehensive plans to adequately address college students’ mental health needs.

Anxiety sensitivity, distress intolerance, and negative interpretation bias strengthen the relationship between trait anxiety and depersonalization

BACKGROUND OBJECTIVES

Depersonalization is common in anxiety disorders, but little is known about factors that influence co-occurring anxiety and depersonalization.

DESIGN

We investigated trait moderators of the relationships between state and trait anxiety and depersonalization to better understand their co-occurrence and to identify potential points of intervention.

METHODS

Adults recruited on Amazon Mechanical Turk (N = 303) completed two computer tasks designed to increase variability in state anxiety and depersonalization as well as several self-report questionnaires.

RESULTS

As hypothesized, anxiety positively predicted depersonalization at both a state level and trait level. Moreover, as hypothesized, the trait anxiety-trait depersonalization relationship was strengthened by greater anxiety sensitivity; distress intolerance; and negative interpretation bias for anxiety sensations, and for depersonalization sensations. None of these hypothesized trait moderators significantly strengthened the state anxiety-state depersonalization relationship.

CONCLUSIONS

These findings suggest that, on a trait level, anxiety and depersonalization more frequently co-occur when people catastrophically misinterpret their symptoms or have lower emotional distress tolerance.

An Integrated mHealth App for Smoking Cessation in Black Smokers With Anxiety: Protocol for a Randomized Controlled Trial

BACKGROUND

Black smokers have greater difficulty in quitting and higher rates of smoking-related diseases and disabilities than the general population. The smoking disparities experienced by this group are, in part, a consequence of multiple chronic life stressors (eg, racial discrimination) that engender increased exposure to interoceptive stress symptoms (eg, anxiety), which can ultimately lead to smoking as a means of immediate emotion regulation.

OBJECTIVE

This study aimed to culturally adapt and initially test a novel mobile intervention (ie, Mobile Anxiety Sensitivity Program for Smoking [MASP]) that targets anxiety sensitivity (AS; a proxy for difficulty and responsivity to interoceptive stress) among Black smokers. The MASP intervention is culturally informed to address interoceptive stress management difficulties among Black smokers and is thus hypothesized to facilitate smoking cessation.

METHODS

In phase 1, a total of 25 Black smokers with elevated AS will be administered MASP for 6 weeks. Following the completion of phase 1, we will further refine the MASP based on qualitative and quantitative data from participants to produce the final MASP iteration. In phase 2, a total of 200 Black smokers with elevated AS will be enrolled and randomly assigned to receive nicotine replacement therapy and either the smartphone-based National Cancer Institute QuitGuide app for standard mobile smoking cessation treatment or the MASP intervention. All participants in phases 1 and 2 will be enrolled remotely and will complete a web-based study screener; smartphone-based baseline assessment; daily smartphone-based ecological momentary assessments for 6 weeks; phone-based end-of-treatment qualitative interviews; and smartphone-based follow-up assessments at postbaseline weeks 1, 2 (quit date), 3, 4, 5, 6, 28, and 54 (weeks 28 and 54 follow-ups will be completed by phase 2 participants only). The MASP intervention is intended to offset barriers to treatment and encourage treatment engagement via smartphones.

RESULTS

This project was funded in September 2020. Phase 1 data collection began in January 2022. Phase 2 data collection is scheduled to begin in July 2022.

CONCLUSIONS

If successful, data from this study will support culturally informed treatment approaches for Black smokers and, pending findings of efficacy, provide an evidence-based mobile intervention for smoking cessation that is ready for dissemination and implementation.

Computer-delivered intervention for individuals with obesity and elevated anxiety sensitivity: feasibility, acceptability, and initial test

Obesity is one the fastest growing public health problems related to numerous chronic diseases and frequently co-occurs with negative mood states. One promising approach to address the heterogeneity of affective vulnerabilities and obesity is to focus on processes (e.g. anxiety sensitivity [AS]) that underpin both conditions. Thus, this study aimed to evaluate the feasibility, acceptability, and initial efficacy of a brief, computer-delivered AS reduction program (AST) for adults with obesity and elevated AS. Participants were 131 individuals with obesity and elevated AS who received either AST or a health information control (HC). Latent growth curve modeling was utilized to examine the effect of treatment condition on change in AS, emotional eating, expectancies of eating to manage mood, and exercise self-efficacy from baseline to 1-week, 2-weeks, and 1-month follow-up. Results indicated it was feasible to recruit and retain individuals with obesity and elevated AS through the 1-month follow-up. Positive qualitative feedback was also provided for both AST and HC. AST was a statistically significant predictor of change in expectancies of eating to manage negative affect. No other statistically significant treatment effects were indicated. Current data provide initial empirical support for future work focused on persons with obesity and elevated AS.

Anxiety and depressive symptoms among adults with obesity and chronic pain: the role of anxiety sensitivity

Obesity and chronic pain frequently co-occur, and this co-occurrence can have potential negative consequences, particularly as it relates to mental health. As such, there is a need to understand potential risk factors for poor mental health among this co-morbid population. Thus, the current study examined the predictive role of anxiety sensitivity (and its sub-facets) on anxiety and depressive symptoms among adults (82.5% female, M_age = 40.2 years, SD = 10.92) with obesity and chronic pain. Results revealed that greater levels of anxiety sensitivity were associated with greater levels of both anxiety and depressive symptoms, with medium to large effect sizes. Post hoc analyses also indicated that specific sub-facets of anxiety sensitivity (cognitive and social concerns) were significant predictors of the criterion variables. The current study highlights the potential clinical utility in targeting anxiety sensitivity among individuals with co-occurring obesity and chronic pain in the treatment of anxiety and depressive symptoms.

The cognitive anxiety sensitivity treatment (CAST) in anxiety prevention - Focus on separation anxiety and interoception

Given the high prevalence and considerable clinical and societal burden of anxiety disorders, preventive measures are urgently warranted to reduce their incidence and overall healthcare impact. Anxiety sensitivity (AS) - a key element in learning theories of anxiety disorders in the context of interoceptive conditioning - constitutes a malleable risk factor of particularly panic disorder and separation anxiety, which share developmental, nosological, epidemiological and pathomechanistic characteristics. The computer-assisted 'Cognitive Anxiety Sensitivity Treatment' (CAST) targeting interoceptive anxiety symptoms (cf. Schmidt et al., 2014) was translated, intensified and culturally adapted to German and evaluated in a sample of 105 healthy adult volunteers with elevated AS (mean ASI-3: 29.5) applying a randomized design. Success of the intervention was measured as a function of AS and separation anxiety (ASA-27) ∼6 weeks (T1) and ∼6 months (T2) after the intervention. As compared to waitlist, CAST resulted in a significant reduction of AS at both T1 and T2. Separation anxiety was not directly reduced by the intervention, but decreased mediated by a decline in AS. A composite interoceptive score capturing changes in sensitivity to respiratory symptoms during the baseline therapist-accompanied CAST session was shown to be predictive of overall response at T1. In sum, CAST-German Version was successfully established as an effective intervention reducing AS, while at the same time indirectly decreasing separation anxiety. A composite interoceptive score predicting treatment response might aid in further delineating risk markers informing targeted preventive interventions for anxiety disorders.

Anxiety Sensitivity as a Malleable Mechanistic Target for Prevention Interventions: A Meta-Analysis of the Efficacy of Brief Treatment Interventions

Anxiety sensitivity (AS) is a transdiagnostic risk factor and potential treatment target for prevention of associated psychopathology and negative health behaviors. We conducted a meta-analysis evaluating the efficacy of brief interventions in at-risk samples for reducing AS and associated clinical/behavioral outcomes (e.g., depression, alcohol use) across 28 studies (1,998 participants). AS targeted interventions, compared to control conditions, evidenced a significant moderate effect size for alleviating AS from pre- to post-treatment (d = 0.54) and approached a large effect size from pre-treatment to short-term follow-up (d = 0.78). The effect size for long-term follow-up did not reach significance (d = 0.29). For clinical/behavioral outcomes, AS interventions demonstrated significant small-to-moderate effect sizes for the three timepoints examined (d's = 0.20-0.41). Our findings help validate AS as a modifiable mechanistic target for prevention efforts.

Anxiety sensitivity and modifiable cardiovascular disease risk factors: the role of pain intensity among individuals with chronic pain

Chronic pain is often comorbid with modifiable cardiovascular disease risk factors, such as obesity and tobacco use. Among individuals with chronic pain, psychological risk factors may increase pain which, in turn, may increase risk for modifiable cardiovascular disease correlates. Thus, the current study examined the explanatory role of pain intensity in the relationship between anxiety sensitivity and two well-documented modifiable cardiovascular disease risk factors. Participants included 396 adults with chronic pain who completed an online survey from a larger study examining chronic pain-mental health relations. Results revealed that higher levels of anxiety sensitivity were related to higher levels of body mass index (BMI) through greater levels of pain intensity. Bi-directional relations were observed between anxiety sensitivity and pain intensity for tobacco risk. The current study highlights a potential transdiagnostic cognitive vulnerability factor, anxiety sensitivity, which may be an important treatment target to reduce modifiable cardiovascular disease risk factors via reductions in pain intensity.

A Prospective Pilot Study of Anxiety Sensitivity and Adolescent Sports-Related Concussion

OBJECTIVE

This study examined the relationship of that anxiety sensitivity (AS) with the initial and ongoing symptoms reported by adolescents after sustaining a sports-related concussion (SRC).

METHOD

Participants were 40 adolescents, ages 13-18, presenting for treatment at a children's sports medicine specialty clinic following a diagnosis of either an SRC or a musculoskeletal injury. After the initial clinic intake, participants completed an online survey at three-time points. Survey measures included the self-report graded symptom checklist and the AS Index-3. Researchers used growth curve analysis to examine the relationship between AS Index-3 scores with initial and ongoing symptom reporting over time. The 20 participants sustaining an SRC were matched by age, gender, and race with 20 musculoskeletal injury controls.

RESULTS

Concussed adolescents with higher AS scores reported more initial symptoms than did those reporting musculoskeletal injury. AS was not related to the rate of symptom reduction over time for either group.

CONCLUSION

Higher AS moderated the relationship between injury type (concussion vs. musculoskeletal injury) and the total number of initial symptoms reported by adolescent participants, with every unit increase in AS yielding a four-unit increase in initial symptoms reporting. Previous research has shown that elevated initial symptom scores are a strong predictor of protracted recovery in concussion. AS is amenable to brief treatment interventions. It is a potential early target for treatment intervention following diagnosis of adolescent SRC.

Anxiety, Depression, and Opioid Misuse Among Adults With Chronic Pain: The Role of Anxiety Sensitivity

OBJECTIVES

The opioid epidemic is a significant public health problem largely driven by opioid prescriptions for chronic pain. Among those with chronic pain, anxiety and depressive symptoms have been linked to opioid misuse, and individual differences in anxiety and depressive symptoms among adults with chronic pain may be important for better understanding pain. Yet, little work has examined mechanisms that may link anxiety and depressive symptoms to opioid misuse among adults with chronic pain. Anxiety sensitivity (AS), or the fear of anxiety-related physical sensations, may be one candidate construct that has been linked independently to anxiety and depressive symptoms as well as opioid misuse.

METHODS

The current survey-based study examined the indirect association of AS in the relation between anxiety and depressive symptoms and opioid misuse among 429 adults with chronic pain currently using prescription opioid medication (73.9% female, Mage=38.32 y, SD=11.07).

RESULTS

Using structural equation modeling, it appears that AS is a potential construct in the interrelation between anxiety and depressive symptoms and opioid misuse. However, an alternative model found equally strong empirical support, as mental health symptoms may serve as an explanatory factor between AS and opioid misuse.

DISCUSSION

Bi-directional effects are apt to be involved among the studied variables. Prospective research is needed to replicate the study results and isolate the temporal patterning between the studied constructs. Nonetheless, the data overall highlight the importance of both AS and anxiety and depressive symptoms in terms of understanding opioid misuse among adults with chronic pain.

Pilot randomized clinical trial targeting anxiety sensitivity: effects on physical activity

Anxiety sensitivity (AS)-the tendency to interpret anxiety as an aversive state-is associated with low rates of physical activity. Previous interventions targeting AS via exercise-based interoceptive exposure have not assessed physical activity as an outcome and are limited by brief follow-up periods. This study replicated and extended previous work by including a 6-week follow-up and assessing physical activity. Participants were 44 sedentary young adults with elevated AS randomized to intervention (six 20-minute sessions of moderate-intensity walking) or assessment-only control. Assessments of AS and physical activity were conducted at baseline and weeks 2 (post-treatment), 4, and 8. Between-group change in AS and physical activity over time was assessed using hierarchical linear modeling. The intervention condition demonstrated a marginally significant reduction in AS compared to control at week 4, which eroded by week 8. There were no significant between-group differences for change in physical activity. Findings indicate that a brief intervention might not be sufficient to produce lasting changes in AS or related exercise avoidance without additional treatment. Intervention effects were weaker than previous reports, which may be due to the greater racial/ethnic diversity of the current sample. Future research should objectively measure physical activity and explore individual variability in response.ClinicalTrials.gov identifier: NCT03128437.

A randomized controlled trial evaluating the efficacy of a brief computerized anxiety sensitivity reduction intervention for health anxiety

It is estimated that individuals with severe health anxiety (HA) utilize 41 %-78 % more healthcare resources than individuals with identified medical diagnoses. Thus, identifying targets for intervention and prevention efforts for HA that are appropriate for primary care or specialty clinic settings is imperative. The aim of the present investigation was to evaluate the effect of a single-session, computerized anxiety sensitivity (AS) intervention on AS and HA. Participants were 68 university students (79.4 % female; M_age = 19.68) with elevated levels of AS and HA. Participants were randomized to either the AS intervention condition or an active control condition and completed self-report and behavioral follow-up assessments at post-intervention, 1-week follow-up, and 1-month follow-up. Results indicated a significant Time x Condition interaction for ASI-3 at each follow-up assessment (all ps < .001), such that individuals in the active condition exhibited greater reductions in AS compared to the control condition. There was no significant Time x Condition interaction for HA at any follow-up. Mediation analyses revealed a significant indirect effect of Condition on changes in HA through changes in AS. No significant effects were observed for behavioral outcomes. Findings suggest that this intervention successfully reduces AS among those who are high in HA and AS and may indirectly contribute to reductions in HA over time through reductions in AS.

The Depression Sensitivity Index: Initial Development and Tests of Convergent and Construct Validity

BACKGROUND

Depression and suicide are prominent and increasing U.S. public health issues, which suggests novel assessment and treatment approaches are needed. Reiss' Expectancy Model of Fear, Anxiety, and Panic states that fear is based on two classes of variables, expectations and sensitivities, which has led to much research on anxiety sensitivity as a significant risk factor for later anxiety psychopathology. Major depressive disorder also includes biased expectations and sensitivities; however, a depression sensitivity rooted in Expectancy Theory has never been formalized. Uncovering depression-related sensitivities may lead to earlier risk detection and prevention before mood disorders develop.

METHOD

The goal of the paper was to create a Depression Sensitivity Index using exploratory factor analysis and item response theory and then conduct tests of convergent and construct validity using structural equation modeling using three independent samples.

RESULTS

indicated two lower order factors: 1) physical and cognitive concerns (DSPCC) and 2) social concerns (DSSC). Factors showed incremental associations with depression (DSPCC), social anxiety (both) and suicidal thoughts and behaviors (DSPCC), above and beyond anxiety sensitivity cognitive concerns. Both factors together predicted depressive disorder diagnoses LIMITATIONS: : Mostly self-report data, large percentage of non-Hispanic White participants in Study 1.

CONCLUSIONS

The results offer initial evidence that expectancy theory applies beyond "fear, anxiety, and panic" and that with further development depression sensitivity could be an important intervention target for prevention of major depressive disorder and suicidal thoughts and behaviors.

Examination of a brief computerized Cognitive Anxiety Sensitivity intervention on obsessive-compulsive symptoms

OBJECTIVES

Despite the existence of several first-line treatments for obsessive-compulsive disorder (OCD), many patients fail to experience symptom reduction and/or do not complete treatment. As a result, the field has increasingly moved towards identifying and treating malleable underlying risk factors that may in turn improve treatment efficacy. One salient underlying risk factor, anxiety sensitivity (AS) cognitive concerns, has been found to be uniquely associated with obsessive-compulsive (OC) symptom dimensions. However, no studies have yet examined whether reductions in AS cognitive concerns will lead to subsequent reductions in OC symptoms.

METHODS

The current study attempted to fill this gap by recruiting individuals reporting elevations on both AS cognitive concerns and at least one OC symptom dimension. Participants were randomly assigned to receive either a one-session AS cognitive concerns intervention (n = 35) or a single health information control session (n = 37). AS cognitive concerns were assessed at post-intervention and one-month follow-up.

RESULTS

The active intervention produced significantly greater reductions in AS cognitive concerns post-intervention than the control intervention. However, this effect was no longer significant at one-month follow-up. Further, while there was not an effect of treatment condition on OC symptoms at one-month follow-up, changes in AS cognitive concerns from baseline to post-intervention mediated changes in OC symptoms at one-month follow-up.

CONCLUSIONS

Findings support previous research attesting to the malleable nature of AS. Extending this research, findings provide initial support for the efficacy of AS interventions among individuals with elevated OC symptoms.

PRACTITIONER POINTS

Clinicians should consider assessing anxiety sensitivity (AS) among patients with obsessive-compulsive disorder. If elevated, clinicians should consider targeting AS as an adjunct to treatment as usual.

Anxiety sensitivity and substance use: Differential levels across individuals primarily using opioids, cannabis, or stimulants

BACKGROUND

The purpose of the current study was to compare levels of anxiety sensitivity (AS) across a treatment-seeking sample of individuals primarily using opioids, stimulants, or cannabis. Consistent with the idea that individuals high in AS may be motivated to use substances with real or perceived anxiolytic properties, it was hypothesized that individuals primarily using opioids or cannabis would evidence higher levels of AS compared to individuals primarily using stimulants.

METHODS

The sample consisted of 110 veterans (including 29 individuals primarily using opioids, 42 primarily using cannabis, and 39 primarily using stimulants) presenting for psychological services to a Posttraumatic Stress Disorder (PTSD) and Substance Use Disorder (SUD) specialty clinic at a large southeastern Veteran Affairs (VA) hospital.

RESULTS

AS levels varied by group with individuals primarily using stimulants evidencing the highest levels followed by those primarily using opioids and then those primarily using cannabis. Individuals primarily using stimulants had statistically significantly higher levels of AS physical concerns compared to individuals primarily using cannabis but not those primarily using opioids. Further, individuals who primarily use opioids did not differ from those primarily using cannabis.

CONCLUSIONS

Taken together, these findings call into question the notion that AS may be negatively related to the use of substances that have anxiogenic properties.

Transdiagnostic Versus Construct-Specific Cognitive Behavioural Therapy for Emotional Disorders in Patients with High Anxiety Sensitivity: A Double-Blind Randomised Clinical Trial

Anxiety sensitivity (AS) is a common vulnerability in emotional disorders. Due to the pathological role of AS, individuals with high AS are faced with emotional problems. Thus, cognitive behavioural interventions try to reduce these problems by targeting AS. The present study aimed to compare the efficacy of transdiagnostic cognitive behavioural therapy (T-CBT) and construct-specific CBT (CS-CBT) on AS, anxiety, depression, and positive and negative affect in these patients. To this end, 40 patients with high AS were randomly assigned to one of the three groups of T-CBT, CS-CBT, and wait list. Participants were assessed using the Anxiety and Related Disorders Interview Schedule for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Anxiety Sensitivity Index-3, Beck Anxiety Inventory, Beck Depression Inventory-II, and Positive and Negative Affect Schedule at baseline, post-treatment, 3-month follow-up, and 6-month follow-up. The findings showed that T-CBT and CS-CBT have a significant effect on AS, anxiety, and negative affect; however, contrary to T-CBT, CS-CBT is not effective for reducing depression and positive affect. T-CBT had a more promising efficacy than CS-CBT in all treatment outcomes. The results show better and more stable efficacy of T-CBT among patients with high AS. It is essential to consider AS as a target for cognitive behavioural intervention for the spectrum of emotional disorders.

Anxiety sensitivity in relation to eating expectancies among college students

Disordered eating is highly prevalent on college campuses and is associated with a host of negative outcomes. To better understand the nature of disordered eating, it is important to examine motivational processes that guide eating behavior. Participants: Participants were a diverse sample of 1,589 college students (80.4% females; M_age=22.2 years, SD = 5.27). Methods: This study examined anxiety sensitivity, a transdiagnostic vulnerability factor, as a predictor of eating expectancies. Results: Results indicated that higher levels of anxiety sensitivity was associated with greater levels of expectancies of eating to help manage negative affect, expectancies of eating to alleviate boredom, and expectancies of eating to lead to feeling out of control. Results were observed over and above variance accounted for by gender, race/ethnicity, and negative affectivity. Conclusions: These findings suggest that college students with higher anxiety sensitivity may have a greater risk for maladaptive eating expectancies.

The Co-occurrence of Pediatric Chronic Pain and Anxiety: A Theoretical Review of a Developmentally Informed Shared Vulnerability Model

The development and maintenance of pediatric chronic pain and anxiety are complex, underscoring the need to better understand the interactive forces contributing to their co-occurrence. The shared vulnerability model (SVM) was developed to explain the co-occurrence of chronic pain and posttraumatic stress disorder in adults. Although many core tenets have been well supported by pediatric research, the SVM has yet to be extended to pediatric pain populations. We propose a developmentally informed pediatric SVM for advancing our understanding of the co-occurrence of pediatric chronic pain and anxiety disorders. The proposed SVM postulates that youth at increased risk for the development of chronic pain and/or anxiety share predisposing vulnerabilities, including anxiety sensitivity, and that these shared vulnerabilities give rise to negative emotional responses (child and parent) in the context of stressful events. Consequences of fear and anxiety, including avoidance behavior, further contribute to the development of chronic pain, anxiety, and their co-occurrence. The parental, school, and peer contexts in which these problems develop and are maintained in youth are pertinent to integrate into a SVM, as pediatric chronic pain and anxiety disorders share several social-contextual risk and maintenance factors. We also highlight new areas of inquiry.

Distress intolerance mediates attentional control on posttraumatic stress symptoms: Evidence from two clinical samples

Theoretical models emphasize the importance of both affective and cognitive risk factors in the development of posttraumatic stress symptoms (PTSS). Two such factors predicting PTSS have been studied extensively: distress intolerance (DI) - an affective factor indicative of the ability to tolerate negative affective states - and attentional control (AC), a cognitive factor reflecting the ability to flexibly shift and maintain attention to goal-relevant tasks. Previous work primarily highlights the independent contributions of DI and AC and their interaction to predict PTSS. Some models, however, suggest a mediational pathway such that AC indirectly affects PTSS via diminished DI. The current paper addressed this gap by first attempting to replicate prior findings, while also exploring this mediation model. Results were examined in two clinical samples - a trauma-exposed sample of adults (study 1; N = 73) and trauma-exposed treatment-seeking adults (study 2; N = 204). Results partially supported our hypotheses; both studies failed to replicate prior moderation findings, but our mediational hypothesis was supported in both samples. Low AC appears to decrease an individual's tolerance for distressing situations, which in turn increases the severity of PTSS. Results suggest that PTSD treatments may benefit by incorporating components of AC, DI, or a combination of the two to mitigate PTSS. Taken together, this study provides a novel examination of how cognitive and affective risk factors, namely AC and DI, work in tandem to increase PTSS.

Transdiagnostic preventative intervention for subclinical anxiety: Development and initial validation

Risk factors associated with the development of anxiety disorders have been identified; however, the development of preventive interventions targeting these risk factors is in the nascent stage. To date, preventive interventions have tended to target specific anxiety disorder symptoms (e.g., panic attacks). Although these interventions are effective at reducing risk for the targeted disorder (e.g., panic disorder), the focus of the intervention is narrow, thereby limiting the dissemination of these interventions. One approach that may broaden the scope of our prevention efforts is the development of a transdiagnostic intervention. Currently, transdiagnostic interventions have only been used in those with diagnosed conditions (e.g., anxiety disorders); however, it stands to reason that a transdiagnostic approach may also be helpful for those at-risk for developing anxiety disorders. The present study reported on the development and use of a brief preventative intervention for those with subclinical anxiety (i.e., worry, social anxiety). Participants were randomized into either a transdiagnostic preventative intervention, focused on reduction of safety aids, or a health focused control group. Participants consisted of sixty-nine individuals with subclinical levels of anxiety. Results revealed significant between group differences in the reduction of social anxiety, worry, and levels of impairment with the active intervention group relative to the control group. Further, change in safety aid utilization was a significant mediator in the association between intervention group and social anxiety and worry at Week 1; however, it was not a significant mediator at Month 1. Implications of these results and avenues for future research are discussed.

Anxiety sensitivity dimensions in young individuals with at-risk-mental states

Anxiety Sensitivity (AS) is a transdiagnostic risk factor involved in the development and maintenance of different psychopathological conditions including anxiety disorders and psychosis. It consists of Physical Concerns (e.g., the belief that palpitations lead to a cardiac arrest), Social Concerns (the belief that observable anxiety reactions will elicit social rejection), and Cognitive Concerns (the belief that cognitive difficulties lead to mental incapacitation). No study investigated whether specific AS dimensions are related to At-Risk Mental States (ARMS). This study compared AS dimensions between young individuals with ARMS, patients after a recently occurred First-Episode Psychosis (FEP) and matched community controls. Based on models of ARMS and previous evidence, it was hypothesized that ARMS individuals have higher physical, social and cognitive concerns than FEP patients and controls. Thirty individuals with ARMS and 30 with FEP and 30 controls recruited from the general population completed the Anxiety Sensitivity Index-3 (ASI-3) and Penn State Worry Questionnaire. ARMS and FEP individuals had higher scores than controls on ASI-3 Cognitive Concerns [F_{( 2,87)}= 11.48, p<.001]. Individuals with ARMS had higher ASI-3 Physical Concerns scores than FEP patients [F_{( 2,87)}= 5.10, p<.01] and at a marginal significance level than controls. No between-group difference was found on Social Concerns. Higher ASI-3 Physical Concerns scores [B = -.324, Wald's χ² ₍₁₎ = 8.29, p < .01] and psychiatric comorbidities [B = -2.726, Wald's χ² ₍₁₎ = 9.33, p < .01] were significantly related to ARMS than FEP. Higher ASI-3 Social Concerns scores were related to FEP, despite at a marginal significance level [B =.213, Wald's χ² ₍₁₎ = 3.79, p = .052]. Interventions for AS Cognitive/Physical Concerns could be incorporated in the treatment of ARMS. A replication of the findings is required. Future longitudinal studies should examine whether Cognitive Concerns predict development of FEP in ARMS to improve early detection and prevention strategies.

Assessing beliefs about the consequences of not just right experiences: Psychometric properties of the Not Just Right Experience-Sensitivity Scale (NJRE-SS)

Although current cognitive conceptualizations of obsessive-compulsive disorder (OCD) emphasize that rituals are performed in order to avoid overtly threatening outcomes, it has also been noted that there are individuals for whom the attempt to correct "not just right experiences" (NJREs) rather than dangerous outcomes per se appear important. This article examines the idea that individuals have differing tolerances for-or sensitivity to-NJREs, in a similar manner as occurs regarding for other experience such as the distinction between disgust propensity and disgust sensitivity. In Study 1, using a nonclinical Italian sample, the NJRE-Sensitivity Scale (NJRE-SS) was created and refined. Its final version consisted of eight items loading on two subscales-an intolerance of NJREs due to their perceived interference with cognitive tasks and due to their interference with enjoyment of life. In Study 2, the factor structured was confirmed in a separate sample. The measure was found to have convergent validity with related measures including a separate measure assessing the severity and frequency of NJREs themselves. However, the NJRE-SS predicted OCD symptoms over-and-above the general NJRE measure, with particularly the interference with cognitive tasks subscale being of importance. Clinical implications are discussed.

A computerized anxiety sensitivity intervention for opioid use disorders: A pilot investigation among veterans

The opioid epidemic is having a disproportionate impact on veterans. Indeed, veterans are twice as likely to die from an accidental overdose than members of the general population, even after accounting for gender and age distribution. Although many veterans seek treatment, a large proportion drop out prematurely and/or relapse highlighting the need to identify malleable factors that may contribute to the recovery process. One such variable is anxiety sensitivity (AS; i.e., fear of anxious arousal). AS is elevated in opioid use populations and is a predictor of treatment dropout among opioid users. Importantly, research suggests that AS is highly malleable; although, no studies have systematically examined such protocols among opioid users. To this end, the purpose of the proposed study was to test the acceptability, feasibility, and utility of a brief, one-session Computerized Anxiety Sensitivity Treatment (termed CAST) delivered to veterans seeking services for an opioid use disorder (OUD). Veterans (n = 16) were assessed at baseline and also at one-week and one-month following CAST. All veterans completed the protocol and reported being interested and engaged during the intervention. Further, small to medium reductions in psychopathology and substance use outcomes were found. Although more work is needed, the current study provides preliminary support for the effectiveness of a brief AS-focused intervention among veterans seeking treatment for an OUD.

Investigating the latent dimensions of posttraumatic stress disorder and the role of anxiety sensitivity in combat-exposed Filipino soldiers

Identifying the optimal factor structure of posttraumatic stress disorder (PTSD) has recently been reinvigorated in literature due to the substantial changes to its diagnostic criteria in the fifth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Currently, six models of PTSD are supported in literature, but there is no consensus on the best-fitting factor structure. Additionally, the extant literature examining the relationship between PTSD symptom-grouping and AS in the latent level has been scarce. The present study's objectives are two-fold: first, we aimed to identify the best-fitted model of PTSD by comparing the six empirically-supported models, and; second, we examined the relationship between the best-fitting model with anxiety sensitivity (AS). Utilizing a sample of 476 combat-exposed soldiers, the results suggest that both the anhedonia and hybrid models provide the best fit to the data, with the anhedonia model achieving slightly better fit indices. Further, the examination on the influence of AS to PTSD reveal that while there is a pattern of decreasing factor loadings and factor correlations when accounting for AS, the changes are not significant to alter the PTSD symptom-structure. Based on these results, our findings suggest further investigation on the possible mediating or moderating mechanisms by which AS may influence PTSD.

Anxiety Sensitivity and Children's Risk for Both Internalizing Problems and Peer Victimization Experiences

In this study, we examined the degree to which children's level of anxiety sensitivity (AS) was a precursor to both internalizing problems and peer victimization experiences. Participants were 581 fourth-grade children (M age = 9.31; 51.8% girls; 42.3% Hispanic/Latinx) and their teachers. Measures of AS, internalizing problems, and peer victimization were collected across a single academic year (Fall, Spring). Structural equation modeling and logistic regression analyses indicated AS predicted future internalizing symptoms as well as self- and teacher-reports of peer victimization. Also, children with heightened AS were 2.70 times more likely to reach elevated levels of self-rated peer victimization and 11.53 times more likely to have clinically elevated internalizing problems. This is the first study to examine prospectively the link between AS and children's peer victimization experiences. We discuss implications of the findings for developing preventative interventions for children at risk for peer victimization and internalizing difficulties.

Test of an Anxiety Sensitivity Amelioration Program for at-risk youth (ASAP-Y)

OBJECTIVE

Adult research supports the efficacy of targeting the malleable risk factor of anxiety sensitivity (AS) in preventing anxiety and related psychopathology. However, very little work has evaluated the impact of AS reduction among youth, which is unfortunate given adolescence is a "core risk" period in terms of disorder onset.

METHOD

The primary project aim was to test the effects of an Anxiety Sensitivity Amelioration Program for Youth (ASAP-Y) among a sample of 88 youth aged 10-14 years with elevated AS. High AS youth and a parent were randomly assigned to either the ASAP-Y, which consisted of psychoeducation and experimenter-led and parent-led exposures, or a general health information control condition.

RESULTS

Youth in the intervention condition sustained low AS levels across the intervention period, and although AS levels in both conditions decreased from baseline to the one-month assessment, this decrease was more pronounced at one-month for youth in the intervention condition. Further, significant indirect effects of condition on one-month anxiety and depression symptoms via reduced AS were detected. Homework compliance rates and self-report data support the acceptability of the ASAP-Y. Contrary to hypotheses, differences between conditions in emotional reactivity elicited using experimental psychopathology methods were not observed.

CONCLUSIONS

The current findings offer preliminary support for the ASAP-Y as an acceptable selective preventive intervention for at-risk youth, with specific anxiety- and depression-related effects through reduced AS.

Childhood anxiety sensitivity, fear downregulation, and anxious behaviors: Vagal suppression as a moderator of risk

Anxiety sensitivity-the fear that anxiety-related sensations will result in catastrophic physical, social, or psychological consequences-is a robust risk factor for clinical anxiety. However, less is known about how anxiety sensitivity may interact with physiological modulation of arousal to predict anxious children's fear responses. The present investigation examined vagal withdrawal as a moderator of the association between anxiety sensitivity and anxious children's ability to downregulate subjective feelings of fear in response to an anxiety-provoking speech task. Observer ratings of anxious behaviors and performance during the task were also examined. It was hypothesized that children's anxiety sensitivity levels would interact with respiratory sinus arrhythmia (RSA) suppression to explain unique variance in subjective fear downregulation, anxious behaviors, and task performance. Participants were 105 children with anxiety disorders (N = 105; M = 10.07 years, SD = 1.22; 57% female) who completed diagnostic interviews, questionnaires, a speech about their family, and an RSA assessment in baseline and speech conditions. Interactions between RSA suppression and anxiety sensitivity predicted unique variance in subjective fear downregulation. Specifically, the greatest difficulties downregulating subjective fear responses were exhibited by children with high anxiety sensitivity and low RSA suppression. Interactions between RSA suppression and anxiety sensitivity did not predict variance in observer ratings of anxious behaviors or task performance. However, higher baseline RSA and speech RSA were significantly associated with fewer anxious behaviors during the speech. Higher baseline RSA was also significantly associated with better speech performance. These findings highlight the importance of vagal withdrawal and its interaction with anxiety sensitivity in predicting downregulation of subjective fear among clinically anxious children.

Psychometric properties of the Iranian version of the Anxiety Sensitivity Index-3 (ASI-3)

INTRODUCTION

Anxiety sensitivity plays a prominent role in the etiology of anxiety disorders. This construct has attracted widespread interest from experts and researchers. The Anxiety Sensitivity Index (ASI-3) is the most common scale for measuring anxiety sensitivity.

OBJECTIVE

To analyze the psychometric properties and factor structure of the ASI-3 in Iranian student samples.

METHODS

220 students (135 women, 85 men) from Kermanshah University of Medical Sciences were selected by the convenience sampling method to evaluate the psychometric properties and analyze the factor structure of the ASI-3. The subjects were also asked to complete the Acceptance and Action Questionnaire-II (AAQ-II), Whiteley Index, Intolerance of Uncertainty, and Neuroticism scales. LISREL and SPSS were used to analyze the data. Cronbach's alpha and correlation coefficients were calculated and confirmatory factor analysis was conducted.

RESULTS

The results of the confirmatory factor analysis revealed a three-factor structure with physical, cognitive, and social components (comparative fit index = 0.94; normed fit index = 0.91; root mean square error of approximation = 0.09). The ASI-3 had positive and significant correlations with health anxiety (0.59), intolerance of uncertainty (0.29), and neuroticism (0.51). Furthermore, the ASI-3 had a negative and significant correlation with the AAQII (-0.58). Cronbach's alpha coefficients for the whole scale and for the physical, cognitive, and social concerns factors were 0.90, 0.74, 0.79, and 0.78, respectively. The invariance of the index was significant compared to the original English version.

CONCLUSION

In general, the results support the adequacy of the psychometric properties of the Persian version of the ASI-3. Theoretical and applied implications will be discussed.

Do Immediate Gains Predict Long-Term Symptom Change? Findings from a Randomized Trial of a Single-Session Intervention for Youth Anxiety and Depression

Single-session interventions (SSIs) can help reduce youth psychopathology, but SSIs may benefit some youths more than others. Identifying predictors of SSIs' effectiveness may clarify youths' likelihoods of benefitting from an SSI alone, versus requiring further treatment. We tested whether pre-to-post-SSI shifts in hypothesized symptom change mechanisms predicted subsequent reductions in youth internalizing symptoms. Data were from a trial evaluating whether an SSI teaching growth mindset (the belief that personality is malleable) reduced youth anxiety and depression. Youths (N = 96, ages 12-15) self-reported growth mindsets, perceived primary control, and perceived secondary control pre- and immediately post-intervention. They self-reported depression and anxiety symptoms at pre-intervention and 3, 6, and 9-month follow-ups. Larger immediate increases in primary control predicted steeper depressive symptoms declines across the follow-up; larger immediate increases in secondary control predicted steeper anxiety symptoms declines. Immediate shifts in proximal intervention "targets" may predict longer-term response to an SSI for youth internalizing distress. CLINICAL TRIALS: Clinicaltrials.gov registration: NCT03132298.

Incidence of panic disorder in patients with non-cardiac chest pain and panic attacks

This study documented the 6-month incidence of panic disorder and its predictors in emergency department patients with panic attacks and non-cardiac chest pain. The assessment included a validated structured interview to identify panic attacks and questionnaires measuring the potential predictors of panic disorder. Presence of panic disorder was assessed 6 months later. The incidence of panic disorder was 10.1 percent ( n = 14/138). Anxiety sensitivity was the only significant predictor of the incidence of panic disorder (odds ratio = 1.06; 95% confidence interval = 1.01–1.12). Patients with panic attacks and non-cardiac chest pain are at an elevated risk for panic disorder. This vulnerability appears to increase with anxiety sensitivity.

Time course of panic disorder and posttraumatic stress disorder onsets

PURPOSE

Posttraumatic stress disorder (PTSD) often co-occurs with panic disorder (PD), with some etiological models positing a causal role of panic reactivity in PTSD onset; however, data addressing the temporal ordering of these conditions are lacking. The aim of this study was to examine the bi-directional associations between PD and PTSD in a nationally representative, epidemiologic sample of trauma-exposed adults.

METHODS

Participants were community-dwelling adults (62.6% women; Mage = 48.9, SD 16.3) with lifetime DSM-IV PTSD criterion A trauma exposure drawn from the 2001/2 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) and re-interviewed in 2004/5 (N = 12,467). Cox discrete-time proportional hazards models with time-varying covariates were used to investigate the bi-directional associations between lifetime PD and PTSD, accounting for demographic characteristics, trauma load, and lifetime history of major depression, generalized anxiety disorder, and social anxiety disorder.

RESULTS

PD was significantly associated with subsequent onset of PTSD (HR 1.210, 95%CI = 1.207-1.214, p < .001), and PTSD was significantly associated with onset of PD (HR 1.601, 95% CI 1.597-1.604, p < .001). The association between PTSD and subsequent PD was stronger in magnitude than that between PD and subsequent PTSD (Z = - 275.21, p < .01). Men evidenced stronger associations between PD and PTSD compared to women.

CONCLUSIONS

Results were consistent with a bidirectional pathway of risk, whereby PD significantly increased risk for the development of PTSD, and PTSD significantly increased risk for PD. Given the association between PTSD and subsequent PD, particularly among men, clinicians may consider supplementing PTSD treatment with panic-specific interventions, such as interoceptive exposure, to prevent or treat this disabling comorbidity.

Anxiety sensitivity and daily cigarette smoking in relation to sleep disturbances in treatment-seeking smokers

Although the association between anxiety and sleep disturbance is well-documented, the underlying mechanisms are less clear. Anxiety sensitivity (AS), the fear of physiological arousal and bodily sensations, is a risk factor for anxiety and poor sleep. Smoking also contributes to poor sleep and may compound the effects of AS on sleep quality. This study evaluated the main and interactive effects of AS and cigarettes/day on sleep quality among smokers. Participants (n = 190) were adult treatment-seeking daily smokers who completed a baseline assessment as part of a larger smoking cessation trial. Sleep quality was self-reported. Results indicated that AS was significantly correlated with greater disturbance in sleep duration, subjective sleep quality, sleep onset latency, sleep disturbance, daytime dysfunction, and sleep medication use. There was a significant interaction between AS and cigarettes/day in terms of sleep onset latency, but not other sleep quality indices. AS was associated with significantly longer sleep onset latency minutes among heavier smokers, but not lighter smokers. Specifically, the association between AS and sleep onset latency was significant for those who smoked ≥ 33 cigarettes/day. AS is a psychological factor that may contribute to poor sleep quality, especially in heavy smokers, and thus may be a promising intervention target.

Exploring anxiety sensitivity in the relationship between pain intensity and opioid misuse among opioid-using adults with chronic pain

Opioid misuse is a significant public health problem. Chronic pain is one highly prevalent factor that is strongly associated with increased risk for opioid misuse. Anxiety sensitivity (fear of anxiety related physical sensations) is an individual difference factor consistently linked to pain experience, and separately, heroin use. The present study examined if anxiety sensitivity may be one factor related to the relationship between pain intensity and opioid misuse among opioid-using adults with chronic pain. Results indicated that anxiety sensitivity total score was significantly associated with the relationship between pain intensity and current opioid misuse, as well as pain intensity and severity of opioid dependence. Overall, results suggest that anxiety sensitivity may be an important assessment and intervention target to ultimately reduce the rates of opioid misuse among adults with chronic pain.

A narrative synthesis of possible causes and risk factors of hoarding behaviours

BACKGROUND

Hoarding is a disorder characterized by excessive acquisition and persistent difficulty in discarding possessions. The behaviour has adverse emotional, physical, social, financial, and legal outcomes for the person with the disorder and family members, and might pose a significant public health problem. Hoarding has been included as a distinct disorder in the Diagnostic and Statistical Manual of Mental Disorders Fifth edition (DSM-5). The prevalence of hoarding disorder is approximately 2-6% globally. The current state of the evidence does not offer clear understanding of the causes of hoarding behaviours. A systematic review of the extant literature was carried out to determine the possible causal factors of hoarding behaviours.

METHODS

This review is conducted in line with PRISMA guidelines. The following electronic databases: Medline through Ovid, EMBASE and PsycINFO were searched for relevant articles published between January 2000 and November 2018. Only articles published in English language were included. Two reviewers independently scrutinized the studies and included them in this review.

RESULTS

Our search strategy returned a total of 396 references. Preliminary findings suggest that individuals with hoarding behaviours may have a genetic susceptibility; abnormal neural activity in the fronto-temporal, para-hippocampal gyrus and insular parts of the brain has also been identified. Traumatic life experiences have also been posited to predispose individuals to hoard.

CONCLUSION

Although the understanding of hoarding disorder hasgrown in recent years, greater efforts are still needed to clarify the etiology and mechanisms of hoarding disorder as these may help in planning of more holistic interventions to treat the problem.

Anxiety sensitivity and opioid misuse among opioid-using adults with chronic pain

Background: The opioid epidemic is a significant public health crisis, and this problem is particularly prevalent among individuals with chronic pain. Accordingly, there is an urgent need for interventions to mitigate the risk for opioid misuse and opioid use disorder among people with pain. Given that mental health problems, specifically anxiety, are common among people who misuse opioids, it is important to examine factors that link mental health problems with opioid misuse to ultimately inform the development of novel interventions. Anxiety sensitivity, a transdiagnostic vulnerability factor defined as the fear of anxiety-related physical sensations, may be one important mechanism in elevated opioid misuse among persons with chronic pain. Objective: Therefore, the current cross-sectional study examined anxiety sensitivity (and construct sub-facets) as a predictor of opioid misuse among adults with chronic pain. Method: Adults reporting chronic pain and prescription opioid use completed an online survey. Results: Anxiety sensitivity was associated with multiple aspects of opioid misuse, including current opioid misuse, severity of opioid dependence, and number of opioids used to get high. The magnitude of effects ranged from medium to large. Associations between anxiety sensitivity and opioid misuse were observed over and above the variance accounted for by age, sex, income, education, perceived health, and pain severity. Conclusion: These findings suggest that anxiety sensitivity may be an important treatment target among adults with chronic pain who misuse opioids. Future research should continue to explore the explanatory relevance of anxiety sensitivity in opioid misuse among individuals with chronic pain.

Prevalence and course of subthreshold anxiety disorder in the general population: A three-year follow-up study

BACKGROUND

This study examined the prevalence, course and risk indicators of subthreshold anxiety disorder to determine the necessity and possible risk indicators for interventions.

METHODS

Data were derived from the 'Netherlands Mental Health Survey and Incidence Study-2' (NEMESIS-2), a psychiatric epidemiological cohort study among the general population (n = 4528). This study assessed prevalence, characteristics, and three-year course of subthreshold anxiety disorder (n = 521) in adults, and compared them to a no anxiety group (n = 3832) and an anxiety disorder group (n = 175). Risk indicators for persistent and progressive subthreshold anxiety disorder were also explored, including socio-demographics, vulnerability factors, psychopathology, physical health and functioning.

RESULTS

The three-year prevalence of subthreshold anxiety disorder was 11.4%. At three-year follow-up, 57.3% had improved, 29.0% had persistent subthreshold anxiety disorder and 13.8% had progressed to a full-blown anxiety disorder. Prevalence, characteristics and course of subthreshold anxiety disorder were in between both comparison groups. Risk indicators for persistent course partly overlapped with those for progressive course and included vulnerability and psychopathological factors, and diminished functioning.

LIMITATIONS

Course analysis were restricted to the development of anxiety disorders, other mental disorders were not assessed. Moreover, due to the naturalistic design of the study the impact of treatment on course cannot be assessed.

CONCLUSIONS

Subthreshold anxiety disorder is relatively prevalent and at three-year follow-up a substantial part of respondents experienced persistent symptoms or had progressed into an anxiety disorder. Risk indicators like reduced functioning may help to identify these persons for (preventative) treatment and hence reduce functional limitations and disease burden.

Anxiety sensitivity, its stability and longitudinal association with severity of anxiety symptoms

Anxiety sensitivity is associated with the onset of panic attacks, anxiety, and other common mental disorders. Anxiety sensitivity is usually seen as a relative stable trait. However, previous studies were inconclusive regarding the longitudinal stability of anxiety sensitivity and differed in study designs and outcomes. The current study examines the stability of anxiety sensitivity over time and its longitudinal associations with severity of anxiety symptoms. Participants from the Netherlands Study of Depression and Anxiety with and without an anxiety, depressive, or comorbid anxiety-depressive disorder diagnosis were included (N = 2052). Stability in anxiety sensitivity over two year follow-up and the longitudinal association between the change in anxiety sensitivity and change in severity of anxiety symptoms were tested. Results indicated that two-year stability of anxiety sensitivity was high (r = 0.72), yet this test-retest estimate leaves room for changes in anxiety sensitivity in some individuals as well. Change in anxiety sensitivity was positively associated with change in severity of anxiety symptoms (B = 0.64 in univariable analysis and B = 0.52 in multivariable analysis). The longitudinal association of anxiety sensitivity with severity of anxiety symptoms indicates that targeting anxiety sensitivity may be of additional benefit in clinical practice.

Anxiety Sensitivity Differentially Predicts Factors of Interpersonal-Psychological Suicide Risk: A Consideration of Specificity

Recent studies have identified anxiety sensitivity (AS) as a risk factor for suicidality; however, limited work has been performed to understand this risk within the context of the interpersonal-psychological theory of suicide (IPTS; Joiner, 2005). The current study examined the relationship between overall AS, each AS subfactor (cognitive, social, and physical), and the three IPTS domains (perceived burdensomeness, thwarted belongingness, and acquired capability). While each AS subfactor uniquely predicted one IPTS domain, greater overall AS only predicted greater acquired capability, suggesting that assessment of AS at the subfactor level may offer us more information about an individual's interpersonal suicide risk.
