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

Abstract
Although exposure is effective for blood-injection-injury (BII) phobia, fear often returns after treatment. While disgust has been implicated in BII phobia, its effects on fear renewal are unclear. To address this knowledge gap, the present study examined the effect of repeated video exposure to fearful and disgusting stimuli in multiple contexts on fear renewal in BII phobia. Individuals with BII phobia (N = 57) were randomized to Disgust-Specific Exposure (DSE) which included exposure to disgusting but threat-irrelevant stimuli (i.e., vomit), Fear-Specific Exposure (FSE) which included exposure to threat-relevant stimuli (i.e., injections), or General Negative Exposure (GNE) which included exposure designed to elicit negative affect (i.e., tornado) without being disgusting or threat-relevant. During session one, participants watched a pre- and post-exposure assessment injection video ("pre/post assessment"), and a novel injection video after exposure to assess renewal effects ("novel 1"). Participants came in one week later to rate the same videos, and a new injection video ("novel 2"). For week one outcomes, comparisons of covariate adjusted means indicated the fear-specific group reported significantly lower levels of anxiety than the general-negative group to the post-exposure and novel 1 stimulus. When presented with the post-exposure stimuli during week two, the disgust-specific and fear-specific groups reported significantly lower levels of anxiety than the general negative group. The fear-specific group also reported significantly lower levels of anxiety than the disgust-specific and general-negative groups when presented with novel 1 and novel 2 stimuli at week two. These findings suggest that repeated exposure to threat-relevant cues in multiple contexts does reduce the return of anxiety. However, repeated exposure to disgusting but threat irrelevant stimuli may also produce some therapeutic effects. The implications of the integration of disgust-relevant processes into exposure-based treatment of BII phobia are discussed.

Abstract
Research suggests that disgust may be linked to the etiology of some anxiety-related disorders. The present investigation reviews this literature and employs separate meta-analyses of clinical group comparison and correlational studies to examine the association between disgust proneness and anxiety-related disorder symptoms. Meta-analysis of 43 group comparison studies revealed those high in anxiety disorder symptoms reported significantly more disgust proneness than those low in anxiety symptoms. Although this effect was not moderated by clinical versus analogue studies or type of disorder, larger group differences were observed for those high in anxiety symptoms associated with contagion concerns compared to those high in anxiety symptoms not associated with contagion concerns. Similarly, meta-analysis of correlational data across 83 samples revealed moderate associations between disgust proneness and anxiety-related disorder symptoms. Moderator analysis revealed that the association between disgust proneness and anxiety-related disorder symptoms was especially robust for anxiety symptoms associated with contagion concerns. After controlling for measures of negative affect, disgust proneness continued to be moderately correlated with anxiety-related disorder symptoms. However, negative affect was no longer significantly associated with symptoms of anxiety-related disorders when controlling for disgust proneness. The implications of these findings are discussed in the context of a novel transdiagnostic model.

Abstract
Blood-injection-injury (BII) phobia is a chronic and debilitating disorder, which has largely been neglected in the child literature. The present paper briefly reviews the aetiology of specific phobias with particular attention to BII and provides an integrated developmental model of this disorder in youth. Evidence-based treatments for child-specific phobias are discussed, and the development of a modified one session treatment (OST) approach to enhance treatment outcomes for BII phobia in children and adolescents is described. This approach is illustrated in two children with a primary diagnosis of BII phobia. The cases illustrate the unique challenges associated with treating BII in youth and the need for a modified intervention. Modifications included addressing the role of pain (e.g., psychoeducation, more graduated exposure steps) and disgust (e.g., disgust eliciting exposure tasks) in the expression of the phobia and fainting in the maintenance of this phobia. Moreover, it is recommended that parents be more actively involved throughout treatment (e.g., education session prior to OST, contingency management training, guidance regarding planning exposure tasks following treatment) and for families to participate in a structured e-therapy maintenance programme post-treatment.

Abstract
Despite growing evidence implicating disgust in the etiology of blood-injection-injury (BII) phobia, the relevance of disgust for exposure-based treatment of BII phobia remains largely unknown. Individuals with BII phobia were randomly assigned to a disgust (view vomit videos) or neutral activation (view waterfall videos) condition. They were then exposed to 14 videotaped blood draws, during which fear and disgust levels were repeatedly assessed. Participants then engaged in a behavioral avoidance test (BAT) consisting of exposure to threat-relevant stimuli. Examination of outcome comparing the identical first and last blood-draw clips revealed that fear and disgust toward blood draws was significantly reduced in both groups. Disgust levels were also found to be more intense for the video stimuli relative to fear levels whereas the opposite was true for BAT stimuli. Contrary to predictions, the disgust induction did not enhance reductions in negative responses to the target video or reduce behavioral avoidance. Growth curve analyses did show that individuals with BII phobia exposed to the disgust induction showed greater initial fear levels during repeated exposure than those in the neutral condition. However, this effect was not consistently observed across different analytic approaches. Changes in fear during exposure were also found to be independent of changes in disgust but not vice versa, and greater initial fear levels during repeated exposure to threat was associated with fear and disgust levels during the BAT. The implications of these findings for conceptualizing the role of disgust in etiology and treatment of BII phobia are discussed.

Abstract
AbstractThe current study examined whether a traditional exposure-based treatment for blood-injection-injury (BII) phobia would be effective at reducing disgust responses to BII stimuli and whether the addition of modules targeting disgust would provide incremental efficacy. Participants, many of whom reported subclinical BII phobia symptoms, underwent one of two single-session exposure protocols, one targeting fear alone, and the other targeting both fear and disgust. Both treatments consisted of education components (fear-only or fear-disgust) and in vivo exposure (fear-only or fear-disgust). Both the fear-only and the fear-disgust treatment groups significantly decreased fear and avoidance behaviour toward BII stimuli over time. The two groups also experienced similar reductions in disgust responses to BII-related stimuli and global as well as domain-specific disgust sensitivity. The effect sizes indicated that the fear-disgust group evidenced greater reduction in symptoms than did the fear-only group. The implications of the results for models of phobia maintenance and treatment are discussed.

Abstract
Although extant research examining predictors of development of Posttraumatic Stress Disorder (PTSD) have focused primarily on fear and anxiety, recent research suggests that a range of different emotional reactions may occur in response to traumatic events. For example, specific aspects of traumatic exposure frequently include either experiencing or witnessing events that may elicit disgust, including injury, death, or sexual assault (e.g., Dalgleish and Power in Behav Res Ther Spec Issue Festschrift Spec Issue John Teasdale 42(9):1069–1088, 2004); McNally in J Anxiety Disord 16(5):561–566, 2002). However, no published research has specifically examined the role of disgust propensity in the development and maintenance of PTSD. Thus, the aim of the present study was to evaluate the relationship between disgust propensity and intrusive symptoms. To this end, 30 undergraduates without symptoms of PTSD were recruited to participate in a distressing film paradigm (for a review of this paradigm see Holmes and Bourne in Acta Psychol 127(3):553–566, 2008). Anxiety, depression, and trait disgust scores were entered hierarchically into a regression equation to predict the number of intrusions during a post-film thought monitoring period. Results indicated that disgust propensity predicted intrusions independent of anxiety and depression. Although still preliminary, results suggest that disgust propensity may be one factor that predicts frequency of intrusive memories after witnessing injury or bodily harm.

Abstract
Research has begun to implicate the role of disgust in the etiology of specific phobias and obsessive-compulsive disorder (OCD). However, it remains unclear if the association between disgust and specific anxiety disorder symptoms is an artifact of trait anxiety or a potential mechanism through which trait anxiety effects specific anxiety disorder symptoms. The present study employed structural equation modeling to differentiate disgust from trait anxiety in the prediction of four types of specific anxiety disorder symptoms in a non-clinical sample (N=352). Results indicate that disgust and trait anxiety latent factors were independently related to spider fears, blood-injection-injury (BII) fears, general OCD symptoms, and OCD washing concerns. However, when both variables were simultaneously modeled as predictors, latent disgust remained significantly associated with the anxiety disorder symptoms, whereas the association between latent trait anxiety and the anxiety disorder symptoms became non-significant or was substantially reduced. Statistical tests of intervening variable effects converged in support of disgust as a significant intervening variable between trait anxiety and spider fears, BII fears, and OCD symptoms (particularly washing concerns). The relevance of these findings for future research investigating the role of disgust in specific anxiety disorders is discussed.

Abstract
Blood phobia differs from other phobias and anxiety disorders in that no attentional bias for blood-related stimuli has been consistently observed. The present study aimed at clarifying this characteristic by investigating electromagnetic brain activity to blood-related and -unrelated pictures in high blood-fearful and non-fearful individuals. Relative to non-fearful controls, high blood-fearful subjects displayed more intense occipito-parietal activation 190-250ms after picture onset, which was interpreted as non-specifically enhanced sensory encoding of visual stimuli. Blood-related stimuli did not elicit different activity patterns in high blood-fearful subjects and controls, supporting the hypothesis that non-specific hypervigilance does not provide a basis for subsequent, specifically enhanced processing of fear-related contents.
