The Three Domains of Disgust Scale: factor structure, psychometric properties, and conceptual limitations

This investigation examined the measurement properties of the Three Domains of Disgust Scale (TDDS). Principal components analysis in Study 1 (n = 206) revealed three factors of Pathogen, Sexual, and Moral Disgust that demonstrated excellent reliability, including test-retest over 12 weeks. Confirmatory factor analyses in Study 2 (n = 406) supported the three factors. Supportive evidence for the validity of the Pathogen and Sexual Disgust subscales was found in Study 1 and Study 2 with strong associations with disgust/contamination and weak associations with negative affect. However, the validity of the Moral Disgust subscale was limited. Study 3 (n = 200) showed that the TDDS subscales differentially related to personality traits. Study 4 (n = 47) provided evidence for the validity of the TDDS subscales in relation to multiple indices of disgust/contamination aversion in a select sample. Study 5 (n = 70) further highlighted limitations of the Moral Disgust subscale given the lack of a theoretically consistent association with moral attitudes. Lastly, Study 6 (n = 178) showed that responses on the Moral Disgust scale were more intense when anger was the response option compared with when disgust was the response option. The implications of these findings for the assessment of disgust are discussed.     

Unpacking cognitive reappraisal: goals, tactics, and outcomes

Studies of emotion regulation typically contrast two or more strategies (e.g., reappraisal vs. suppression) and ignore variation within each strategy. To address such variation, we focused on cognitive reappraisal and considered the effects of goals (i.e., what people are trying to achieve) and tactics (i.e., what people actually do) on outcomes (i.e., how affective responses change). To examine goals, we randomly assigned participants to either increase positive emotion or decrease negative emotion to a negative stimulus. To examine tactics, we categorized participants' reports of how they reappraised. To examine reappraisal outcomes, we measured experience and electrodermal responding. Findings indicated that (a) the goal of increasing positive emotion led to greater increases in positive affect and smaller decreases in skin conductance than the goal of decreasing negative emotion, and (b) use of the reality challenge tactic was associated with smaller increases in positive affect during reappraisal. These findings suggest that reappraisal can be implemented in the service of different emotion goals, using different tactics. Such differences are associated with different outcomes, and they should be considered in future research and applied attempts to maximize reappraisal success.     

Effects of experienced disgust on habituation during repeated exposure to threat-relevant stimuli in blood-injection-injury phobia

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.     

Disgust vulnerability and symptoms of contamination-based OCD: descriptive tests of incremental specificity

The present investigation examines the incremental association between disgust propensity and sensitivity and contamination-based obsessive-compulsive disorder (OCD) symptoms. Structural equation modeling in Study 1 indicated that general disgust was related to contamination fear even when controlling for negative affect in a nonclinical sample. Evidence was also found for a model in which the effect of negative affect on contamination fear is mediated by general disgust. Study 1 also showed that both disgust sensitivity and disgust propensity uniquely predicted contamination fear when controlling for negative affect. Growth curve analyses in Study 2 indicated that higher baseline contamination fear is associated with less reduction in contamination fear over a 6-week period as disgust sensitivity increases even when controlling for negative affect. Lastly, disgust propensity was associated with concurrent levels of excessive washing symptoms among patients with OCD in Study 3 when controlling for depression. Implications of these findings from nonclinical, analogue, and clinical samples for future research on the specificity of disgust-related vulnerabilities in the etiology of contamination concerns in OCD are discussed.     

Emotional expressions and visual search efficiency: specificity and effects of anxiety symptoms

Although facial expressions are thought to vary in their functional impact on perceivers, experimental demonstration of the differential effects of facial expressions on behavior are lacking. In the present study, we examined the effects of exposure to facial expressions on visual search efficiency. Participants (n = 31) searched for a target in a 12 location circle array after exposure to an angry, disgusted, fearful, happy, or neutral facial expression for 100 ms or 500 ms. Consistent with predictions, exposure to a fearful expression prior to visual search resulted in faster target identification compared to exposure to other facial expressions. The effects of other facial expressions on visual search did not differ from each other. The fear facilitating effect on visual search efficiency was observed at 500-ms but not at 100-ms presentations, suggesting a specific temporal course of the facilitation. Subsequent analysis also revealed that individual differences in fear of negative evaluation, trait anxiety, and obsessive-compulsive symptoms possess a differential pattern of association with visual search efficiency. The experimental and clinical implications of these findings are discussed.     

Worry and the anxiety disorders: A meta-analytic synthesis of specificity to GAD

Although worry is central to the diagnosis of generalized anxiety disorder (GAD), it is also commonly observed in other anxiety disorders. In this meta-analytic review, we empirically evaluated the extent to which worry is specific to GAD relative to patients with other anxiety disorders, those with other psychiatric disorders, and nonpsychiatric controls. A total of 47 published studies (N = 8,410) were included in the analysis. The results yielded a large effect size indicating greater severity/frequency of worry, meta-worry, and domains of worry among anxiety disorder patients v. nonpsychiatric controls (d = 1.64). In contrast to the many differences emerging from comparisons between anxiety disordered patients and nonpsychiatric controls, when anxiety disordered patients were compared to people with other psychiatric disorders they differed only on severity/frequency and not on meta-worry or domains of worry. A large effect size indicating greater severity/frequency of worry, meta-worry, and domains of worry among patients with GAD v. nonpsychiatric controls was also found (d = 2.05). However, differences between GAD and those with other psychiatric disorders also emerged for severity/frequency of worry. GAD was associated with greater worry difficulties than other anxiety disorders, which generally did not differ from those with other psychiatric disorders and each other. The implications of these findings for conceptualizing worry in GAD and other anxiety disorders, and the potentially moderating effects of age and gender are discussed.     

Fear and Loathing: A Meta-Analytic Review of the Specificity of Anger in PTSD

The available empirical literature suggests that anger may be characteristic of posttraumatic stress disorder (PTSD). Meta-analytic strategies were used to evaluate the extent to which the experience of anger is specific to PTSD rather than anxiety disorders in general. Thirty-four anxiety disorder patient samples (n = 2,169) from 28 separate studies were included in the analysis. Results yielded a large effect size indicating greater anger difficulties among anxiety disorder patients versus controls. Compared to control samples, a diagnosis of PTSD was associated with significantly greater difficulties with anger than was any other anxiety disorder diagnosis. Other anxiety disorder diagnoses did not differ significantly from each other. However, the specific association between PTSD and anger did vary depending on the anger domain assessed. Difficulties with anger control, anger in, and anger out significantly differentiated PTSD from non-PTSD anxiety disorder samples, whereas difficulties with anger expression, state anger, and trait anger did not. These findings are discussed in the context of future research on the role of anger in PTSD.     

Who am I to judge? Self-disgust predicts less punishment of severe transgressions

Although recent research has shown that experimentally induced disgust and the personality trait of disgust sensitivity is associated with more severe moral decisions, no study to date has examined how disgust, experienced specifically toward the self, influences morally relevant decisions. Participants (n = 109) in the present study completed a measure of self-disgust, disgust sensitivity, and depressive symptoms and then evaluated nonoffenses, moderate offenses, and severe offenses with regard to level of disgust and punishment deserved. The results showed that self-disgust significantly predicted more disgust and punishment ratings of nonoffenses when controlling for individual differences in both depressive symptoms and disgust sensitivity. In contrast, self-disgust significantly predicted less disgust and punishment ratings of severe offenses when controlling for individual differences in depressive symptoms and disgust sensitivity. The implications of these findings for further conceptualizing how the heterogeneous construct of disgust operates in the moral domain are discussed.
