Objectives: This preliminary online study investigated the short-term effects of self-distancing, worry, and distraction on anxiety and worry-related appraisals among individuals high in worry.

Design And Methods:  = 104 community members high in trait worry were randomly assigned to think about a personally identified worry-provoking situation using self-distancing (SC), worry (WC), or distraction (DC). Participants rated their anxiety (Visual Analogue Scale for Anxiety) and appraisals of the situation (Perceived Probability, Coping, and Cost Questions) at post-task and one-day follow-up.

A robust negative association exists between self-reported posttraumatic stress disorder (PTSD) and self-reported interpersonal relationship functioning. However, the extent to which each member of a dyad's subjective PTSD ratings influence the other's subjective relationship functioning ratings is less understood. The present study tested: (a) associations between self- and partner-PTSD severity ratings and relationship functioning ratings and (b) whether exposure to the index trauma, gender, and relationship type (i.

Unlabelled: Chronic worry and generalized anxiety disorder (GAD) symptoms are associated with infrequent savoring, and high dampening, of positive emotions. The goal of the present study was to investigate the indirect role of GAD-relevant processes, including intolerance of uncertainty (IU), fear of negative emotional contrasts, and negative beliefs about positive emotion and its regulation, in the relationship between GAD symptom severity and the tendency to engage in dampening and not savor positive emotions. Community participants ( = 233) completed questionnaires online.

Background: The role of interpersonal relationship functioning in trauma recovery is well-established. However, much of this research has been done with cross-sectional samples, often years after trauma exposure, using self-report methodology only, and is focused on intimate relationship adjustment.

Methods: The current study investigated the longitudinal associations between interpersonal (intimate and non-intimate) relationship functioning and clinician- and self-reported posttraumatic stress disorder (PTSD) symptoms in 151 recently (within the past 6 months) traumatized individuals.

Safety perspectives of generalized anxiety disorder (GAD) propose that safety perception is critical to regulating anxiety. Reduced safety processing may contribute to persistent worry and anxiety that extend to recognizably safe contexts. We explored whether individuals higher in worry and intolerance of uncertainty (IU), central characteristics of GAD, display poorer recognition and use of safety cues, and whether safety perception is related to anxiety.

Context: The Attention Training Technique (ATT, Wells, 1990) is an intervention guiding individuals to focus, shift, and divide their attention in response to sounds presented in an audiorecording. The ATT has long been recommended for generalized anxiety disorder (GAD); however, there is insufficient research on its effects on excessive worry and related processes.

Objectives: This experiment examined whether the ATT is more efficacious than a control intervention at reducing worry and modifying worry-related processes (e.

Mental imagery plays a prominent role across psychopathology. However, its quality and role in generalized anxiety disorder (GAD) have not been examined as extensively as in other disorders. The goal of the present study was to obtain a better understanding of general imagery processes and individual differences in people with GAD.

Background And Objectives: Individuals with high anxiety sensitivity (AS) display negative interpretive biases in response to uncomfortable but nondangerous physical sensations. Research suggests that modifying interpretation biases associated with AS leads to changes in AS. The present study sought to replicate and extend this research by addressing limitations of previous studies, increasing the amount of training and adding a follow-up period.

Negative interpretation bias, the propensity to make threatening interpretations of ambiguous information, is associated with symptoms of generalized anxiety disorder (GAD). Apart from its relationship with intolerance of uncertainty (IU), little is known about what explains the presence of this cognitive bias in GAD. One factor may be negative urgency (NU), the tendency to take rash action when distressed, which is related to GAD symptoms and to cognitive biases in nonclinical populations.

This study examined excessive reassurance seeking (or positive feedback seeking; PFS) and negative feedback seeking (NFS) in individuals with social anxiety disorder (SAD), generalized anxiety disorder (GAD), or no history of mental health difficulties. A 2-week daily diary method was used to examine potential group differences in the frequency, topics, and targets of PFS and NFS. The SAD and GAD groups reported significantly higher feedback seeking (FS) than the healthy group on self-report questionnaires.

A number of studies have examined the association of intolerance of uncertainty (IU) to trait worry and generalized anxiety disorder (GAD). However, few studies have examined the extent of overlap between IU and other psychological constructs that bear conceptual resemblance to IU, despite the fact that IU-type constructs have been discussed and examined extensively within psychology and other disciplines. The present study investigated (1) the associations of IU, trait worry, and GAD status to a negative risk orientation, trait curiosity, indecisiveness, perceived constraints, self-oriented and socially prescribed perfectionism, intolerance of ambiguity, the need for predictability, and the need for order and structure and (2) whether IU is a unique correlate of trait worry and of the presence versus absence of Probable GAD, when overlap with other uncertainty-relevant constructs is accounted for.

Although numerous studies have provided support for the notion that intolerance of uncertainty plays a key role in pathological worry (the hallmark feature of generalized anxiety disorder (GAD)), other uncertainty-related constructs may also have relevance for the understanding of individuals who engage in pathological worry. Three constructs from the social cognition literature, causal uncertainty, causal importance, and self-concept clarity, were examined in the present study to assess the degree to which these explain unique variance in GAD, over and above intolerance of uncertainty. N = 235 participants completed self-report measures of trait worry, GAD symptoms, and uncertainty-relevant constructs.

Background And Objectives: GAD symptoms are associated with greater negative urgency, a dimension of impulsivity defined as the tendency to act rashly when distressed. This study examined the degree to which intolerance of negative emotional states and intolerance of uncertainty account for the association between negative urgency and GAD symptoms.

Design: An analysis of indirect effects evaluated whether intolerance of negative emotions and intolerance of uncertainty uniquely account for the association between negative urgency and GAD symptom severity.

The inhalation of 35% carbon dioxide (CO₂) induces panic and anxiety in people with panic disorder (PD) and in people with various other psychiatric disorders. The anxiogenic effect of CO₂ in people with eating disorders has received sparse attention despite the fact that PD and bulimia nervosa (BN) have several common psychological and neurobiological features. This study compared CO₂-reactivity across three groups of participants: females with BN, females with PD, and female controls without known risk factors for enhanced CO₂-reactivity (e.

People with generalized anxiety disorder (GAD) engage in maladaptive coping strategies to reduce or avoid distress. Evidence suggests that uncertainty and negative emotions are triggers for distress in people with GAD; however, there may also be other triggers. Recent conceptualizations have highlighted six types of experiences that people report having difficulty withstanding: uncertainty, negative emotions, ambiguity, frustration, physical discomfort, and the perceived consequences of anxious arousal.

This experiment examined the degree to which it is more beneficial for individuals with generalized anxiety disorder (GAD) to engage in repeated exposure to mental imagery of the same feared scenario versus varying the exposure content. On three consecutive days, individuals with GAD (N=57) spent 20min writing about: (1) the same worst case scenario (consistent exposure; CE), (2) variations of their worst case scenario (varied exposure; VE), or (3) a neutral topic (neutral control; NC). Participants in the CE condition displayed significant decreases in worry, acute cognitive avoidance, and intolerance of uncertainty from baseline to 1-week follow-up; participants in the VE and NC conditions did not.
