Mitchell BJ, Coifman KG, Olatunji BO. Is disgust more resistant to extinction than fear? A meta-analytic review of laboratory paradigms. Behav Res Ther 2024; 174:104479. [PMID: 38301293 DOI: 10.1016/j.brat.2024.104479] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2023] [Revised: 01/05/2024] [Accepted: 01/09/2024] [Indexed: 02/03/2024]
Abstract
Disgust can be acquired via evaluative conditioning; a process by which a neutral stimulus (conditioned stimulus; CS) comes to be evaluated as disgusting due to its pairing with an inherently disgusting stimulus (unconditioned stimulus; US). Research has shown that conditioned disgust responses are resistant to extinction which may have implications for disorders (i.e., contamination-based obsessive-compulsive disorder, specific phobias, and post-traumatic stress disorder) in which heightened disgust has been implicated. Importantly, extinction is the primary mechanism by which exposure therapies are thought to achieve symptom reduction for these disorders. Exposure therapies were originally modeled on fear extinction, whereas disgust extinction was largely overlooked until recently. Accordingly, differences in the degree to which learned disgust and fear can be attenuated via extinction learning remains unclear. The present investigation was a meta-analysis directly comparing the degree of extinction of conditioned disgust (n = 14) and conditioned fear (n = 14) in laboratory paradigms. Extinction was operationalized as the standardized mean difference (SMD) in evaluative ratings between the CS+ (the CS paired with the US) and CS- (the unpaired CS) after extinction training. Results of a subgroup analysis indicated that disgust (SMD = 0.52) was significantly more resistant to extinction than fear (SMD = 0.37). Additionally, a series of meta-regression analyses indicated that extinction was not influenced by important study characteristics (e.g., sex, age, number of conditioning and extinction trials). The findings suggest that extinction-based approaches may be less effective at attenuating learned disgust and research is needed to better optimize treatments for disgust-related disorders.

Abstract
OBJECTIVES The selection pressures exerted by pathogens have played important roles in shaping the biology and behavior of animals, including humans. Immune systems recognize and respond to cues of infection or damage by coordinating cellular, humoral, and metabolic shifts that promote recovery. Moreover, animals also possess a repertoire of behavioral tools to help combat the threat of pathogens, often referred to as the behavioral immune system. Recently, researchers have begun to examine how cognitive, affective, and behavioral disease avoidance mechanisms interact with the biological immune system. METHODS The present study explored relationships among individual differences in behavioral immune system activity (e.g., pathogen disgust), shifts in SARS-CoV-2 infection risk (i.e., 7-day case averages), and immune function in a community cohort from McLennan County, Texas, USA (n = 387). RESULTS Levels of disease concern were not consistently associated with immune markers. However, serum levels of IFN-γ, TNF-α, IL-2, and IL-8, as well as serum killing ability of Escherichia coli, each varied with case counts. Additional analyses found that case counts also predicted changes in stress physiology, but not subjective measures of distress. However, follow-up mediation models did not provide evidence that relationships between case counts and immunological outcomes were mediated through levels of stress. CONCLUSIONS The present project provides initial evidence that markers of immune function may be sensitive to changes in infection risk during the COVID-19 pandemic. This adds to the growing body of research finding relationships among behavioral and biological pathogen management mechanisms.

Abstract
INTRODUCTION Although adaptive defense mechanisms are useful in helping us avoid getting injured, they are also triggered by medical interventions and procedures, when avoidance is harmful. A body of previous results showed that both fear and disgust play a pivotal role in medical avoidance. However, the underlying mechanisms are not fully understood. Thus, the aim of the current study was to examine the effects of experience, perceived control, and pain on medical avoidance with disgust and fear as mediating factors from an evolutionary perspective. METHODS We assessed participants' knowledge of and experience with medical procedures, former negative medical experiences, and health-related information; their life history strategy variation; pain-related fear and anxiety of medical procedures; perceived control over emotional reactions and extreme threats; disgust sensitivity; blood-injury-injection phobia and medical treatment avoidance. RESULTS We found that more knowledge, experience, and a slower life strategy were linked to a greater level of perceived control and attenuated emotional reactions. Further, better ability to control affective and stress reactions to negative experiences was linked to reduced disgust and fear of pain, and thus might mitigate the level of perceived threat, and diminish fear and disgust reactions. DISCUSSION More knowledge and experiences, better perceived control together with reduced disgust and fear of pain can decrease the probability of avoiding medical situations. Implications to treatment are discussed. Results support the importance of targeting these contextual factors in prevention to increase the likelihood of people attending regular screenings or seeking medical care when needed.

Abstract
Introduction Considered a part of the behavioral immune system (BIS), disgust sensitivity is expected to be adjusting as a response to the actual level of the environmental health risks. Methods In this preregistered study, we tested the hypothesis that disgust sensitivity would be higher during the COVID-19 pandemic compared to the pre-pandemic period in pregnant women. In this between-subject study with a longitudinal trend design, we administered the Disgust Scale-Revised to 200 pregnant women before the pandemic and to 350 pregnant women during the pandemic. Results We found a small but significant effect of the pandemic on disgust sensitivity, such that higher disgust sensitivity was found in women pregnant during the pandemic. This effect was stronger in primiparae, however, the interaction between parity and the pandemic period was not significant. Disgust sensitivity decreased with age. No differences in terms of nausea and vomiting were found between the women pregnant before and during the pandemic. Discussion Our findings indicate that although BIS is presumed to function as a complex mechanism to prevent health-threatening behaviors, its activation in pregnant women during the COVID-19 pandemic is rather weak.

Abstract
Disgust seems to play an important role in moral judgment. However, it is unclear whether the role of disgust in moral judgment is limited to certain kinds of moral domains (versus many) and/or certain types of disgust (versus many). To clarify these questions, we conducted a multilevel meta-analysis ( k = 512; N = 72,443) on relations between trait disgust sensitivity and moral judgment (disgust-immorality association). Main analyses revealed a significant overall mean disgust-immorality association ( r = .23). Additionally, moderator analyses revealed significant specificity in disgust type and moral domain (grounded in Moral Foundations Theory): effects were stronger for (a) sexual disgust compared to pathogen disgust, (b) sanctity moral judgments compared to other domains of moral judgments, and (c) sexual-sanctity associations compared to other disgust type-moral domain pairings.

Abstract
Exposure therapy in virtual reality is successful in treating anxiety disorders. Studies on exposure and response prevention in virtual reality (VERP) in obsessive-compulsive disorder (OCD) are rare, and it is unclear whether distress associated with other emotions than anxiety (e.g., disgust) can be evoked. The present study aimed to investigate whether distress can be induced during VERP in patients with contamination-related OCD (C-OCD) and a primary feeling of disgust. We treated eight female patients with C-OCD with the primary emotion of disgust over six weeks with VERP and assessed their OC symptoms before and after the intervention period with the Y-BOCS. We measured subjective units of distress (SUD), heart rate and skin conductivity (arousal), sense of presence, and simulator sickness during four consecutive exposure sessions. VERP was able to induce distress and arousal. The qualitative feedback was heterogeneous and sense of presence moderate. Patients' OC symptoms reduced over the treatment period with medium to large effect sizes, but only two patients were considered responders; two patients discontinued treatment due to lack of treatment success. Although VERP was able to induce distress and arousal associated with disgust and evoked a moderate sense of presence, the low rate of symptom reduction diminishes the positive results. Possible reasons for the heterogeneous results and implications are discussed. Trial registration: German Registry for Clinical Studies (DRKS00016929), 10.04.2019.

Abstract
Evolutionary theories of disease avoidance propose that humans have a set of universal psychological processes to detect environmental cues indicative of infectious disease. These processes then initiate cognitive, emotional, and behavioral responses that function to limit contact with harmful pathogens. Here, we study the conditions under which people exhibit behavioral avoidance of others with a contagious illness or a physical injury (i.e., a broken leg), and the potential mechanisms that underlie this behavior. Across three studies, participants were given the option of sitting at one of two workstations previously occupied by two confederates, one of whom either showed visible symptoms of a cold (contagion condition), wore a lower-leg orthopedic boot and used crutches (broken leg condition), or showed no signs of illness or physical injury (control). We found strong evidence that adults explicitly avoid contact with individuals who show symptoms of a contagious illness. Further, we provide some evidence that adults also avoid individuals with a physical injury, but that this behavior might be driven by implicit, unconscious processes. The findings are discussed in terms of implications for the healthy avoidance of contagion, and the risk for potential stigmatization of non-contagious groups.

Abstract
Although various demographic and psychosocial factors have been identified as correlates of influenza vaccine hesitancy, factors that promote infectious disease avoidance, such as disgust proneness, have been rarely examined. In two large national U.S. samples (Ns = 475 and 1007), we investigated whether disgust proneness was associated with retrospective accounts of influenza vaccine uptake, influenza vaccine hesitancy, and eventual influenza vaccine uptake, while accounting for demographics and personality. Across both studies, greater age, higher education, working in healthcare, and greater disgust proneness were significantly related to greater likelihood of previously receiving an influenza vaccine. In Study 2, which was a year-long longitudinal project, disgust proneness prospectively predicted influenza vaccine hesitancy and eventual vaccine uptake during the 2020–2021 influenza season. Findings from this project expand our understanding of individual-level factors associated with influenza vaccine hesitancy and uptake, highlighting a psychological factor to be targeted in vaccine hesitancy interventions.

Abstract
While disgust is a clinically and theoretically relevant construct for selective eating, limited research has examined how different aspects of disgust relate to selective eating severity in adults. Thus, the present study sought to 1) compare disgust propensity (how easily people are disgusted) and disgust sensitivity (how unpleasant disgust is) across a spectrum of selective eaters, 2) explore the specificity of the associations between disgust sensitivity/propensity and selective eating across selective eating and related phenotypes, and 3) explore whether the relationship between selective eating and disgust is food-specific. Participants were 554 adults recruited on Amazon's Mechanical Turk who completed cross-sectional surveys on study constructs. The sample was recruited to over-represent individuals with high levels of selective eating. Results support that disgust propensity, but not sensitivity, was elevated in the impaired selective eating group compared to non-impaired selective eaters and non-selective eaters. Only the selective eating phenotype was independently associated with both disgust sensitivity and propensity. Correlation results supported that the associations between selective eating and disgust were specific to the disgust elicited by food (i.e., animal protein, fruits, vegetables). Overall, results support that disgust propensity and disgust sensitivity play a role in selective eating. Results imply that disgust sensitivity associated with selective eating appears limited to the food domain and may be more specific to disgust eliciting food itself, rather than signs of food contamination or spoilage.

Abstract
We developed and examined the construct validity of the Disgust Avoidance Questionnaire (DAQ) as a measure of people’s inclination to prevent experiencing disgust (disgust prevention) and to escape from the experience of disgust (disgust escape). In a stepwise item-reduction (Study 1; N = 417) using Exploratory Factor Analysis (EFA) based on a 4-subscale distinction (behavioral prevention, cognitive prevention, behavioral escape, cognitive escape), we selected 17 items from a pool of potential items. In order to incorporate the conceptual overlap between dimensions of disgust avoidance, focus (prevention vs. escape), and strategy (behavioral avoidance vs. cognitive avoidance), we specified an adapted model. In this model, we allowed each item to load on one type of dimension and one type of strategy, resulting in four overlapping factors (prevention, escape, behavioral avoidance, cognitive avoidance). Evaluation of this overlapping 4-factor model (Study 2; N = 513) using Exploratory Structural Equation Modeling (ESEM) and Confirmatory Factor Analysis (CFA) showed promising model fit indices, factor loadings, factor correlations, and reliability estimates for three of the four factors (prevention, behavioral avoidance, cognitive avoidance). Those three subscales also showed good convergent validity. In contrast, the results related to the escape factor may call the suitability of self-report to assess disgust escape into question. In light of the exploratory nature of the project, future examinations of the DAQ’s validity and applicability to more diverse samples are essential. A critical next step for future research would be to examine the DAQ’s criterion validity and the distinctive roles of the DAQ subscales in (clinical) psychological constructs and processes.

Abstract
Previous research has shown that intrusive thoughts in obsessive-compulsive disorder (OCD) often focus on emotionally significant aspects of individuals' lives (e.g., values and beliefs). The current study sought to expand our understanding of OC symptoms related to sexual orientation (SO-OC symptoms) by investigating the roles of homophobia (i.e., negative attitudes, affect, and behaviors toward individuals with a same-gender orientation) and disgust propensity and sensitivity. A total of 592 self-identified heterosexual college students were recruited to complete measures of homophobia, disgust propensity and sensitivity, and SO-OC symptoms. Results of separate parallel mediation analyses indicated that the relationships between homophobic affect/attitudes and avoidance/aggression on one hand, and SO-OC symptoms on the other, were partially mediated specifically by disgust sensitivity, after controlling for gender. Theoretical and clinical implications are discussed, including how homophobia can be conceptualized as a disgust response in the treatment of SO-OC symptoms, as well as how other constructs of potential interest (sexual and moral disgust, religiosity, conservative sexual ideology) can be examined in future research.

Abstract
The emotion of disgust evolved as a way to protect oneself from illness and is associated with aspects of disease avoidance. Disgust Scale–Revised (DS-R) (Olatunji et al., 2008) measures the disgust propensity of three kinds of disgust (core, animal reminder, contamination). Contextual factors, such as academic background, might influence DS-R scoring, especially among medical students, where the notion of disease is central. We examined DS-R scoring and the choice of postgraduate studies in medical (n = 94) and psychology (n = 97) students. In an anonymous web-based survey, participants completed the DS-R and a questionnaire including plans for postgraduate studies. Females outnumbered males and scored higher in total DS-R score (p = 0.003). Psychology students scored higher in all three kinds of disgust (p < 0.001 for core disgust and animal reminder, p = 0.069 for contamination disgust), indicating a higher level of disease avoidance. Medical students willing to follow Internal Medicine scored higher in core disgust (p < 0.05), while psychology students willing to study Experimental Psychology scored lower in the animal reminder subscale (p = 0.019 and p < 0.001 for the association between these subscales and the orientation of Medical and Psychology Students, respectively). In conclusion, disgust propensity as rated by DS-R is related to academic background and orientation preferences in postgraduate studies.

[PMID: 32682277 DOI: 10.1016/j.janxdis.2020.102272] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2020] [Revised: 06/26/2020] [Accepted: 06/29/2020] [Indexed: 01/21/2023]
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
The COVID-19 public health crisis has led to extensive recommendations by officials to contain its spread. Anxiety regarding contracting the virus is prominent in the public. Specific routes to anxiety over disease contraction are under studied. It is expected that a contributory feature of fear of contracting COVID-19 involve disgust propensity and sensitivity, emotional reactions that are part of a broader behavioral immune system (BIS). A total of N = 908 Chinese adults (mean age = 40.37 years, SD = 9.27; n = 752 female) participated in a survey distributed between February 24 and March 15, 2020. Participants completed measures of anxiety sensitivity, disgust propensity and sensitivity, and fear of contracting COVID-19. Results support a moderating relationship between both disgust propensity and sensitivity in the relationship between physical concerns associated with anxiety sensitivity and fear of contracting COVID-19. These results lend support for individual variation in the activation of the BIS. Recommendations for public education to target individuals who may experience mental health consequences from pandemics are provided.

Abstract
BACKGROUND Individuals with extreme food avoidance such as Avoidant Restrictive Food Intake Disorder (ARFID) experience impairing physical and mental health consequences from nutrition of insufficient variety or/and quantity. Identifying mechanisms contributing to food avoidance is essential to develop effective interventions. Anxiety figures prominently in theoretical models of food avoidance; however, there is limited evidence that repeated exposures to foods increases approach behavior in ARFID. Studying disgust, and relationships between disgust and anxiety, may offer novel insights, as disgust is functionally associated with avoidance of contamination from pathogens (as may occur via ingestion) and is largely resistant to extinction. METHOD This exploratory, cross-sectional study included data from 1,644 adults who completed an online questionnaire. Participant responses were used to measure ARFID classification, picky eating, sensory sensitivity, disgust, and anxiety. Structural equation modeling tested a measurement model of latent disgust and anxiety factors as measured by self-reported frequency of disgust and anxiety reactions. Mediational models were used to explore causal ordering. RESULTS A latent disgust factor was more strongly related to severity of picky eating (B ≈ 0.4) and ARFID classification (B ≈ 0.6) than the latent anxiety factor (B ≈ 0.1). Disgust partially mediated the association between anxiety and picky eating and fully mediated the association between anxiety and ARFID. Models testing the reverse causal ordering demonstrated poorer fit. Findings suggest anxiety may be associated with food avoidance in part due to increased disgust. CONCLUSIONS Disgust may play a prominent role in food avoidance. Findings may inform novel approaches to treatment.

Abstract
The Disgust Scale has been designed to measure disgust propensity—the individual ease in experiencing disgust. The present study aimed to explore the validity, reliability, the factor structure, and the measurement invariance of the Greek version of the Disgust Scale-Revised (DS-R). A sample of 754 healthy participants completed the Greek version of the DS-R. A subset (n = 363) also completed the revised Symptom checked list and the Eysenck Personality Questionnaire, in order to examine the concurrent validity. Exploratory and Confirmatory factor analyses in different subsets were used to examine the factor structure. Multiple indicators–multiple causes model (MIMIC) models were used to assess the measurement invariance across gender and age. Demographic influences were assessed using t-tests, ANOVA, and Pearson’s correlations. Exploratory factor analysis concluded to two and three factor models, with a factor structure similar to the ones proposed in the literature. Confirmatory factor analysis and bi-factor analysis provided evidence in favor of the three-factor solution. Measurement invariance test revealed differences in six items across gender, and three items across age. The psychometric properties of the factors were satisfactory. Demographic influences on the responses were present, especially with respect to gender. The Greek version of the DS-R demonstrated satisfactory psychometric properties, making it suitable for use for the Greek population.

Responsibility/Threat Overestimation Moderates the Relationship Between Contamination-Based Disgust and Obsessive-Compulsive Concerns About Sexual Orientation. ARCHIVES OF SEXUAL BEHAVIOR 2018; 47:1109-1117.

Abstract
Disgust has been shown to perform a "disease-avoidance" function in contamination fears. However, no studies have examined the relevance of disgust to obsessive-compulsive (OC) concerns about sexual orientation (e.g., fear of one's sexual orientation transforming against one's will, and compulsive avoidance of same-sex and/or gay or lesbian individuals to prevent that from happening). Therefore, we investigated whether the specific domain of contamination-based disgust (i.e., evoked by the perceived threat of transmission of essences between individuals) predicted OC concerns about sexual orientation, and whether this effect was moderated/amplified by obsessive beliefs, in evaluation of a "sexual orientation transformation-avoidance" function. We recruited 283 self-identified heterosexual college students (152 females, 131 males; mean age = 20.88 years, SD = 3.19) who completed three measures assessing disgust, obsessive beliefs, and OC concerns about sexual orientation. Results showed that contamination-based disgust (β = .17), responsibility/threat overestimation beliefs (β = .15), and their interaction (β = .17) each uniquely predicted OC concerns about sexual orientation, ts = 2.22, 2.50, and 2.90, ps < .05. Post hoc probing indicated that high contamination-based disgust accompanied by strong responsibility/threat overestimation beliefs predicted more severe OC concerns about sexual orientation, β = .48, t = 3.24, p < .001. The present study, therefore, provided preliminary evidence for a "sexual orientation transformation-avoidance" process underlying OC concerns about sexual orientation in heterosexual college students, which is facilitated by contamination-based disgust, and exacerbated by responsibility/threat overestimation beliefs. Treatment for OC concerns about sexual orientation should target such beliefs.

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
We investigated whether self-ratings of health are affected by a symptom rating. A diary including a one-item self-rating of health (“pre–self-rated health”; 1 = excellent, 7 = very poor), a subsequent 26-item rating of symptoms, and thereafter a second (identical) health rating (“post–self-rated health”) was completed by 820 persons 21 times. Self-rated health worsened significantly ( p < .0001) after the symptom rating, from 2.72 pre–self-rated health (95% confidence interval: 2.70–2.74) to 2.77 post–self-rated health (95% confidence interval: 2.75–2.79) and more so in persons who reported more symptoms ( b = .058, p < .05). The results support the notion that subjective health perception is influenced by attending to symptoms, especially so in persons with a high symptom burden.

Abstract
OBJECTIVE To investigate the relationship between the severities of symptom dimensions in obsessive-compulsive disorder (OCD) and white matter alterations. METHODS We applied tract-based spatial statistics for diffusion tensor imaging (DTI) acquired by 3T magnetic resonance imaging. First, we compared fractional anisotropy (FA) between 20 OCD patients and 30 healthy controls (HC). Then, applying whole brain analysis, we searched the brain regions showing correlations between the severities of symptom dimensions assessed by Obsessive-Compulsive Inventory-Revised and FA in all participants. Finally, we calculated the correlations between the six symptom dimensions and multiple DTI measures [FA, axial diffusivity (AD), radial diffusivity (RD), mean diffusivity (MD)] in a region-of-interest (ROI) analysis and explored the differences between OCD patients and HC. RESULTS There were no between-group differences in FA or brain region correlations between the severities of symptom dimensions and FA in any of the participants. ROI analysis revealed negative correlations between checking severity and left inferior frontal gyrus white matter and left middle temporal gyrus white matter and a positive correlation between ordering severity and right precuneus in FA in OCD compared with HC. We also found negative correlations between ordering severity and right precuneus in RD, between obsessing severities and right supramarginal gyrus in AD and MD, and between hoarding severity and right insular gyrus in AD. CONCLUSION Our study supported the hypothesis that the severities of respective symptom dimensions are associated with different patterns of white matter alterations.

Abstract
Although some studies suggest that the association between disgust proneness (DP) and obsessive-compulsive symptoms (OCS) is specific to the contamination subtype, others suggest that DP is associated with OCS more broadly. To examine if the discrepant findings may partially reflect differences in self-report measures used, this investigation employed structural equation modeling to examine the association between DP and OCS in three samples that completed different combinations of measures of DP, OCS, and anxiety/negative affect. In Study 1 (n=626), the path from DP to contamination-based OCS was significantly stronger than the path from DP to non-contamination OCS when controlling for anxiety sensitivity. In Study 2 (n=403), the results showed that the path from DP to contamination-based OCS did not significantly differ from the path from DP to non-contamination OCS when controlling for negative affect. Lastly, Study 3 (n=296) showed that the path from DP to contamination-based OCS was significantly weaker than the path from DP to non-contamination OCS. These findings highlight that the self-report measures employed is an important moderator when making inferences about the association between DP and contamination-based OCS and non-contamination OCS.

Abstract
Objective: To investigate empathic abilities in patients with obsessive-compulsive disorder (OCD) compared to control subjects. OCD is characterized by persistent obsessions and compulsions. Previous studies have proposed specific emotion recognition deficits in patients with OCD. The ability to recognize emotion is part of the broad construct of empathy that incorporates mentalizing and experience-sharing dimensions. Methods: Twenty-four subjects with a diagnosis of OCD and 23 control subjects underwent empathic measures. Results: Patients with OCD compared to control subjects showed deficits in all mentalizing measures. They were incapable of understanding the mental and emotional states of other people. On the other hand, in the sharing experience measures, the OCD group was able to empathize with the emotional experience of other people when they expressed emotions with positive valence, but were not able to do when the emotional valence was negative. Conclusion: Our results suggest that patients with OCD show a difficulty in mentalizing ability, whereas the deficit in sharing ability is specific for the negative emotional valence.

Abstract
The purpose of this study was to apply a set of rarely reported psychometric indices that, nevertheless, are important to consider when evaluating psychological measures. All can be derived from a standardized loading matrix in a confirmatory bifactor model: omega reliability coefficients, factor determinacy, construct replicability, explained common variance, and percentage of uncontaminated correlations. We calculated these indices and extended the findings of 50 recent bifactor model estimation studies published in psychopathology, personality, and assessment journals. These bifactor derived indices (most not presented in the articles) provided a clearer and more complete picture of the psychometric properties of the assessment instruments. We reached 2 firm conclusions. First, although all measures had been tagged "multidimensional," unit-weighted total scores overwhelmingly reflected variance due to a single latent variable. Second, unit-weighted subscale scores often have ambiguous interpretations because their variance mostly reflects the general, not the specific, trait. Finally, we review the implications of our evaluations and consider the limits of inferences drawn from a bifactor modeling approach.

Abstract
Despite the upsurge of research on disgust, the implications of this research for the investigation of cultural pollution beliefs has yet to be adequately explored. In particular, the sensitivity of both disgust and pollution to a common set of elicitors (e.g., bodily emissions, disease, and death) suggests a common psychological basis, though several obstacles have prevented an integrative account, including methodological differences between the relevant disciplines. Employing a conciliatory framework that embraces both naturalistic (evolutionary) and humanistic levels of explanation, this article examines the dynamic reciprocal process by which contamination/contagion appraisals in individuals serve to shape-and are in turn shaped by-culture-specific pollution beliefs. This complex interrelationship is illustrated by examining ancient Near Eastern and modern ethnographic documentation of pollution beliefs, highlighting the underappreciated function of these pollution beliefs as folk theories for the spread of infectious disease. By evaluating how pollution beliefs (as also modern germ theory) shape contamination appraisals in individuals, it will be argued that cultural inheritance has played a much larger role in guiding disease avoidance behavior than has been previously recognized.

Abstract
Disgust, in addition to fear, is a prominent emotional state associated with avoidance of distressing stimuli. While most of the research in disgust has been conducted in relation to Obsessive-Compulsive Disorder (OCD), recent data has also implicated disgust in the etiology of anxiety disorders in general. Studies have shown that decreases in disgust are key to symptom reduction in individuals with OCD. However, there has been little empirical work exploring whether these interventions are efficacious for childhood anxiety disorders that present with prominent disgust components. This study examined how disgust propensity in children with anxiety disorders responds to cognitive-behavioral therapy (CBT) with an emphasis on exposure. Forty-one children, ages 7 to 17, with anxiety disorders were evaluated for disgust propensity and were treated with intensive, weekly, CBT. It was found that disgust levels decreased following treatment across all anxiety disorder diagnoses, where children with primary OCD exhibited significantly greater reductions. Clinical implications and suggestions for further research of the treatment of disgust in relation to childhood anxiety disorders are discussed.
