Background: This paper reports on the outcomes of a proof-of-principle study for the Exposure Therapy Consortium, a global network of researchers and clinicians who work to improve the effectiveness and uptake of exposure therapy. The study aimed to test the feasibility of the consortium's big-team science approach and test the hypothesis that adding post-exposure processing focused on enhancing threat reappraisal would enhance the efficacy of a one-session large-group interoceptive exposure therapy protocol for reducing anxiety sensitivity.

Methods: The study involved a multi-site cluster-randomized controlled trial comparing exposure with post-processing (ENHANCED), exposure without post-processing (STANDARD), and a stress management intervention (CONTROL) in students with elevated anxiety sensitivity.

The connection between stress and skin disease has been extensively documented; however, there are no empirical studies investigating the incidence of traumatic event exposure and posttraumatic stress (PTS) symptoms among dermatology patients. To address this gap in the literature and begin to understand the associations between PTS symptoms and skin disease symptoms, this study used a sample of adults with self-reported skin disease symptoms to examine: (1) rates of potentially traumatic event (PTE) exposure and PTS symptoms; and (2) the association between PTS symptoms and skin-related quality of life, controlling for relevant covariates. Data were collected online through Cloud Research, and participants completed a battery of self-report measures.

Approximately one-third of adults with chronic respiratory disease (CRD) have comorbid depressive and anxiety disorders; yet these disorders are often unrecognized in this patient population. Transdiagnostic processes such as anxiety sensitivity (AS) are useful for identifying mechanisms underlying psychological and heath conditions. The Short-Scale AS Index (SSASI) is a brief self-report measure of AS which has potential clinical utility among CRD populations to evaluate psychological distress and inform comprehensive care.

Introduction: Distress during pregnancy and postpartum is common and contributes to poor infant and maternal outcomes, such as developmental delays and mental health disorders, respectively. Anxiety sensitivity, or fear of the symptoms of anxiety (eg, palpitations, confusion), is a risk factor known to increase distress across psychological and health-related conditions. Given the physiologic and emotional changes that occur during the perinatal period, anxiety sensitivity may be a salient risk factor for maternal distress.

Article Synopsis
  • Misophonia is a disorder where individuals have a low tolerance for specific sounds or their related stimuli, but lack of a clear definition has slowed research and treatment development.
  • From June 2020 to January 2021, a committee of experts used a modified Delphi method to create a consensus definition of misophonia through multiple rounds of voting, revision, and exclusion of candidate statements from existing literature.
  • The resulting definition, approved by at least 80% of the committee members, aims to unify researchers and clinicians in their efforts to understand and assist those affected by misophonia.

Existing literature demonstrates strong links between emotion regulation (ER) difficulties and depression. Although high rates of depression are observed among individuals with body dysmorphic disorder and skin disease, little is known about these co-occurring syndromes. To advance our understanding of a vulnerable population, this study examined facets of ER difficulties in relation to depression among adults with skin disease symptoms and body dysmorphic concerns (N = 97).

Many dermatology patients experience social anxiety symptoms; however, few studies have investigated vulnerabilities contributing to this distress. Anxiety sensitivity (AS), or the fear of the consequences of anxiety, warrants consideration given its association with social anxiety and dermatological symptoms, respectively. The purpose of this investigation was to investigate the role of AS in social anxiety symptoms in two samples of adults with psychodermatological conditions.

Although behavioral inhibition (BI) is clearly identified as a temperamental risk factor for childhood anxiety psychopathology, much less is known about whether the strength of this association may vary as a function of parasympathetic nervous system regulation in children with anxiety disorders. To build upon extant research in this area, the present study examined whether respiratory sinus arrhythmia (RSA) can explicate the conditions in which BI is linked to increased symptom severity among anxiety-disordered children (N = 44; M = 9.61 years, SD = 1.

Individuals with social anxiety disorder (SAD) commonly experience panic attacks and evidence increased anxiety sensitivity (AS) specific to noticeable anxiety sensations. Interoceptive exposure (IE) is an effective treatment for reducing AS, but few IE tasks target fears of blushing, sweating, or trembling, which are incorporated within AS social concerns and especially feared by individuals with SAD. The primary study aims were trifold: (1) identify novel IE tasks that produce blushing, sweating, and/or trembling; (2) assess the intensity of sensations and anxiety produced by a series of novel and validated IE tasks; and (3) evaluate the incremental validity of combining an IE task and a speech task.

Individuals with posttraumatic stress disorder (PTSD) exhibit deficits in cognitive and emotional processes. PTSD severity is positively associated with anxiety sensitivity (AS) and difficulties in emotion regulation, and difficulties in emotion regulation mediate the relation between AS and PTSD. However, previous research has not examined the interactive nature of these variables.
