Anxiety sensitivity as a predictor of panic disorder symptoms: a prospective 3-year study

Trauma in childhood is associated with greater pain catastrophizing but not anxiety sensitivity: a cross-sectional study

Introduction

Adverse life experiences have been identified as a possible vulnerability factor for chronic pain. This association could result from the effect of trauma on the psychological state of individuals. Previous studies found childhood trauma to be associated with pain catastrophizing and anxiety sensitivity, both of which have been associated with an increased risk of chronic pain. However, it is unknown whether trauma in adulthood affects these variables and whether the effect on pain catastrophizing is independent of confounds such as depression and anxiety.

Objectives

To test the effect of childhood and adulthood trauma on pain catastrophizing and anxiety sensitivity whilst controlling for depression and anxiety.

Methods

In the current study, we conducted an online survey in the United Kingdom in a chronic pain sample (N = 138; 123 women; age range 19-78). We analysed whether there is an association between different types of trauma (both in childhood and through the lifespan), pain catastrophizing, and anxiety sensitivity while controlling for anxiety and depression.

Results

We found that childhood trauma (particularly emotional abuse) significantly predicts pain catastrophizing, even when controlling for depression and anxiety, whereas it did not have a significant effect on anxiety sensitivity. Trauma through the lifespan (not childhood) did not have a significant effect on anxiety sensitivity nor did it have a significant effect on pain catastrophizing.

Conclusions

Our results show that the life stage in which trauma occurs is key in its psychological effects on patients with chronic pain. Furthermore, it shows that trauma affects some psychological variables but not others.

Factor structure of the anxiety sensitivity index-3 in a sample of older adults

Anxiety sensitivity is a transdiagnostic risk factor for internalizing psychopathology in children and adults. Several factor analytic studies have examined the factor structure of anxiety sensitivity in children, adolescents, and adults. However, to date, no studies have specifically examined the factor structure of the Anxiety Sensitivity Index-3 in older adults. The purpose of the current study was to compare the fit of a correlated three-factor, higher-order, and bifactor model of the Anxiety Sensitivity Index-3 (ASI-3) in a sample of older adults. Participants were 856 older adults aged 60-94 recruited through Qualtrics Panels. Confirmatory factor analyses demonstrated good model fit for the bifactor model and the higher-order model and adequate fit for the correlated three-factor model. These results suggests that the ASI-3 is a valid tool assessing anxiety sensitivity in older adults. Limitations and future directions are discussed.

A study in University of Ruhuna for investigating prevalence, risk factors and remedies for psychiatric illnesses among students

There is no comprehensive study on the mental health of Sri Lankan undergraduate in higher education, as most existing studies have been done for medical students only. It is unknown how academic and environmental factors contribute for the prevalence of psychiatric illnesses. Further, there is no sufficient information on the student/university based remedies to reduce the psychological distress of students. This research is carried out to find the overall psychological distress, well-being, prevalence percentages of psychiatric illnesses, associated risk factors, and student/university remedies to overcome them. We use standard questionnaires to screen for psychiatric illnesses, and we analyze the responses for our own questionnaire using Binary logistic regression analysis to identify demographic factors, academic factors, and environmental factors causing each mental disorder. We use Pearson correlation coefficient to identify correlation between prevalence of each psychiatric illnesses. All 13 psychiatric illnesses were found with a moderate correlation among diseases having a mean prevalence percentage of 28 and a standard deviation of 14.36, despite the prevalence of well-being factors among students and only 8% are clinically diagnosed. 89% of the students were suffering from at least one psychiatric illness and 68% were found to be psychologically distressed. Sets of overall and individual demographic, academic, and environmental risk factors contributing for the prevalence of a psychiatric illness in general and in particular were identified respectively after a binary logistic regression analysis. 61% of the students don’t receive psychiatric help from the university and are using their own remedies. The universities must consider the environmental and academic risk factors associated with psychiatric illnesses and design curriculum, expand resources, and provide counseling services to reduce the impact of risk factors.

Are Patients at Risk for Developing Panic Disorder After an Emergency Department Visit With Noncardiac Chest Pain?

BACKGROUND

Panic disorder (PD) is common in emergency department (ED) patients with noncardiac chest pain (NCCP). The literature suggests that initially PD-free patients may be at increased risk of developing PD in the months or years following an ED visit.

OBJECTIVES

This study aims to determine the incidence of PD in the 2 years following an ED visit with NCCP and to identify predictors of incident PD.

METHODS

This study was conducted using a longitudinal, observational design. Five hundred and eighty-five patients with NCCP (without PD) were recruited in two EDs. They underwent an interview and completed a series of questionnaires assessing anxiety disorders, perceived social support, psychological distress, anxiety sensitivity, comorbidities, and stressful life events. PD was assessed 6 months, 1 year, and 2 years after the initial interview.

RESULTS

PD incidence was 11.1% (95% confidence interval: 8.7-13.9) in the two years following the baseline assessment. Anxiety sensitivity (odds ratio = 1.08; 95% confidence interval: 1.04-1.11; P < .001) and stress related to life events (odds ratio = 1.14; 95% confidence interval: 1.06-1.24; P = .001) significantly predicted incident PD.

CONCLUSIONS

Patients with NCCP are at high risk for developing PD in the 2 years following an ED visit with NCCP. Anxiety sensitivity and stress related to life events may be promising clinical targets for preventive interventions.

Association between Uncinate Fasciculus Integrity and Agoraphobia Symptoms in Female Patients with Panic Disorder

Objective

Although neural correlates of sub-clinical agoraphobia (AG) symptoms have been previously suggested, only a few studies evaluating structural changes of the brain have been conducted in agoraphobic patients with panic disorder (PD). We investigated and compared white matter (WM) micro-structural alterations between PD patients with AG (PD ＋ AG) and those without AG (PD − AG).

Methods

Our study included 56 female PD patients, of which 25 were diagnosed with AG and 31 were diagnosed without AG. Diffusion tensor imaging was performed to investigate micro-structural changes in the WM tracts related to fronto-temporo-occipital areas (uncinate fasciculus, cingulum bundle, inferior longitudinal/fronto-occipital fasciculus, fornix column and body, and fornix/stria terminalis). All participants were subjected to the Anxiety Sensitivity Inventory-Revised (ASI-R), Beck Depression Inventory-II (BDI-II), and Albany Panic and Phobia questionnaires.

Results

The fractional anisotropy values of the right uncinate fasciculus in PD ＋ AG were significantly lower than that of PD − AG and showed significant correlations with BDI-II and ASI-R total scores. Mean diffusivity and radial diffusivity values of the right uncinate fasciculus were significantly higher in PD ＋ AG as compared to PD − AG.

Conclusion

Our findings suggest that the uncinate fasciculus may be associated with AG symptoms in PD, possibly through demyelination. Our findings may contribute to the neurobiological evidence regarding the association between AG and WM structural changes in PD.

Genetic variation in neuropeptide Y interacts with childhood trauma to influence anxiety sensitivity

BACKGROUND AND OBJECTIVES

Anxiety sensitivity (AS) refers to a fear of the negative implications of anxiety, and arises due to gene-environment interactions. We investigated whether genetic variation in two neuropeptides implicated in the stress response, neuropeptide Y (NPY) and pituitary adenylate cyclase-activating polypeptide receptor 1, interacted with childhood trauma (CT) to influence AS.

DESIGN AND METHODS

This cross-sectional study examined the CT x genetic variant effects on AS in 951 adolescents who self-identified as Xhosa or South African Colored (SAC) ethnicity.

RESULTS

In Xhosa females, the NPY rs5573 A allele and rs3037354 deletion variant were associated with increased (p = 0.035) and decreased (p = 0.034) AS, respectively. The interaction of CT and the NPY rs5574 A allele increased AS in SAC female participants (p = 0.043). The rs3037354 deletion variant protected against AS with increased CT in SAC male participants (p = 0.011).

CONCLUSIONS

The NPY rs5574 A allele and rs3037354 deletion variant interact with CT to act as risk and protective factors, respectively, for AS in an ethnicity- and sex- differentiated manner. Our results reaffirm the role of NPY and gene-environment interactions in anxiety-related behaviors and reinforce the need for psychiatric genetics studies in diverse populations.

Separation Anxiety Disorder in Panic Disorder Patients with and without Comorbid Agoraphobia

Objective: Previous studies have focused on the relationship between childhood separation anxiety disorder (SAD) and adult panic disorder (PD)-agoraphobia. It is not clear enough whether SAD, which continues into adulthood, is associated with PD with and without comorbid agoraphobia in adult patients. Our primary hypothesis was that PD patients with comorbid agoraphobia had a higher rate of SAD that continues into adulthood than those without agoraphobia. We also hypothesized that adulthood SAD symptoms were more likely to be associated with PD-agoraphobia than PD without agoraphobia.Method: 151 patients who were diagnosed with PD with (n = 106), and without comorbid agoraphobia (n = 45) were compared using Panic and Agoraphobia Scale, Structured Clinical Interview for Separation Anxiety Symptoms, Separation Anxiety Symptom Inventory, Adult Separation Anxiety Questionnaire, and State-Trait Anxiety Inventory. We performed Student's t-test, Pearson correlation test, and multiple linear regression analysis in this study.Results: PD patients with comorbid agoraphobia were more likely to have SAD both in childhood and adulthood (p = .028), than those without agoraphobia. There were mild to moderate significant correlations between PD severity and state anxiety (p = .002), trait anxiety (p = .006), and SAD in childhood (p = .049), and in adulthood (p = .001). SAD in adulthood (β = 0.278, Exp(B) = 0.136, p = .003), and state anxiety (β = 0.236, Exp(B) = 0.164, p = .012) significantly predicted the severity of PD in patients with comorbid agoraphobia.Conclusion: SAD that continues in adulthood may be related to the severity of PD in patients with agoraphobia. Our findings might provide some evidence of the role of SAD in adulthood in patients with adult-onset PD-agoraphobia.

Role of panic appraisal in predicting the severity of panic and agoraphobic symptoms

OBJECTIVE

The present study examined the contribution of panic appraisal (PA) dimensions to the prediction of panic and agoraphobic symptoms, above and beyond anxiety sensitivity (AS), among patients with panic disorder. PA dimensions consist of anticipated panic, perceived panic consequences, and panic coping efficacy.

METHOD

Panic disorder patients (N = 84, 60.7% female, M = 38 years) completed self-report measures of panic and agoraphobic symptoms, three dimensions of PA, AS, anxiety, and depression symptoms.

RESULTS

PA dimensions significantly contributed to the prediction of overall and all facets of panic and agoraphobic symptoms, as well as anxiety symptoms, but not depressive symptoms, above and beyond AS. Of the three PA dimensions, both anticipated panic and panic coping efficacy uniquely contributed to agoraphobic avoidance after controlling for AS and the other dimensions of PA.

CONCLUSION

PA dimensions may emerge as an important predictor of panic and agoraphobic or anxiety symptoms.

Examining the cross-sectional and longitudinal effects of anxiety sensitivity on indicators of disease severity among patients with inflammatory arthritis

Few studies have investigated anxiety sensitivity (AS) in the context of inflammatory arthritis (IA), despite evidence of a relationship between AS and pain. This study examined cross-sectional and longitudinal relationships between AS and indicators of IA severity in 148 participants with IA. AS and its factors (social, physical, cognitive) were self-reported. Arthritis severity was physician-assessed (disease activity scales) and self-reported (physical function; pain and fatigue). Cross-sectional correlations assessed the association between AS and arthritis severity outcomes. Longitudinal multivariable mixed-effect regressions assessed the association of AS total and AS factors at each visit with disease severity outcomes. All AS factors were significantly and positively correlated (at the same visit) with function, pain, and fatigue. AS total significantly predicted pain, fatigue, and function. Cognitive AS significantly predicted fatigue, and physical AS significantly predicted pain and fatigue. Social AS significantly predicted pain, fatigue, function and weighted joint count (articular burden). AS is associated with several indicators of disease severity among those with IA; unique findings emerged across factors with the broadest disease impact by social AS. The AS factors, especially social AS, may contribute to the development and severity of IA symptoms, which may have implications for interventions.
