Measure Of Disgust Sensitivity Research Articles

Science interrupted Our attempt to study disgust sensitivity and the development of political attitudes among children and their parents.

Recent research contends that the behavioral immune system, operating largely outside conscious awareness, motivates individuals to exhibit higher levels of prejudice toward unfamiliar out-groups. This research finds that individual variance in disgust sensitivity correlates with support for political policies that facilitate the avoidance of out-groups. We were interested in developing less intrusive indicators of disgust sensitivity via olfactory measures (i.e., ratings of disgusting odors) and behavioral measures (e.g., willingness to touch disgusting objects) and studying the association between measures of disgust sensitivity and in-group bias among children and adults. We submitted a registered report to conduct this research and received an in-principle acceptance. Unfortunately, unforeseen events impaired our data collection, leaving us with a limited sample (nchildren = 32, nadults = 29) and reducing our ability to draw reliable conclusions from our results. In this essay, we describe our motivation and plan of research, the events that made completing the research impossible, and our preliminary results. In doing so, we hope to offer support for studying the effects of the behavioral immune system, even in ways that we did not originally plan. We conclude with a reflection on the value of registered reports for advancing science.

Weirdness of disgust sensitivity items predicts their relationship to purity moral judgments

Disgust sensitivity predicts judgments of moral issues, especially when they concern transgressions of the purity domain. The reason for this domain-specific relationship is unclear. One potential explanation is that measures of disgust sensitivity and purity transgressions share an important characteristic: They are weird. We test this “weirdness overlap” hypothesis by examining whether weirdness of disgust sensitivity items relates to purity moral judgments (total N = 805). Weirder disgust sensitivity items were more strongly associated with moral judgments of purity, but not care, transgressions, suggesting support for the weirdness overlap hypothesis. However, the implications of this finding are limited as we find that eliminating the weirdest items from disgust sensitivity measures does not affect the tendency for the association between disgust sensitivity and moral judgments to be especially pronounced for purity transgressions. Although weirdness of disgust sensitivity items is associated with the disgust sensitivity-purity link, it cannot explain why disgust sensitivity is more strongly related to moral judgments of purity transgressions.

Disgusting clusters: trypophobia as an overgeneralised disease avoidance response

ABSTRACTIndividuals with trypophobia have an aversion towards clusters of roughly circular shapes, such as those on a sponge or the bubbles on a cup of coffee. It is unclear why the condition exists, given the harmless nature of typical eliciting stimuli. We suggest that aversion to clusters is an evolutionarily prepared response towards a class of stimuli that resemble cues to the presence of parasites and infectious disease. Trypophobia may be an exaggerated and overgeneralised version of this normally adaptive response. Consistent with this explanation, individuals with trypophobia, as well as comparison individuals, reported aversion towards disease-relevant cluster stimuli, but only the trypophobic group reported aversion towards objectively harmless cluster stimuli that had no relevance to disease. For both groups the level of aversion reported was predicted uniquely by a measure of disgust sensitivity. Scaled emotion ratings and open-ended responses revealed that the aversive response was predominantly based on the disease avoidance emotion, disgust. Many open-ended responses also described skin sensations (e.g. skin itching or skin crawling). These findings support the proposal that individuals with trypophobia primarily perceive cluster stimuli as cues to ectoparasites and skin-transmitted pathogens.

Investigating perceptions of disgust in older adult residential home residents

Objectives: As people become increasingly physically dependent as they make the transition into older age, they may lose the ability to control bodily functions. Problems with eating, voiding and washing can be linked with feelings of disgust and, given the necessity for some of being assisted with intimate care activities, it has been suggested that self-focused disgust and concerns over the disgust of others may become important preoccupations in older people, with the potential to further impair their quality of life.Method: In a mixed-methods study, feelings of disgust in 54 physically dependent older adults living in residential homes were investigated. Participants completed measures of disgust sensitivity, mood, and two new scales assessing feelings of self-disgust and perceived other-disgust related to intimate care activities. Six of the residents who reported high levels of self-disgust also participated in semi-structured interviews.Results: Results indicated that disgust was uncommon. Where present, self-disgust was related to perceptions of others’ feelings of disgust and general disgust sensitivity. These results were benchmarked against 21 community-dwelling older adults, who reported believing they would feel significantly more disgusting if they were to start receiving assistance. A thematic analysis identified the importance of underlying protective factors, the use of strategies and carer characteristics in ameliorating feelings of disgust.Conclusion: The results are discussed with reference to the disgust literature, with recommendations being made for ways in which self-disgust can be minimised in those making the transition to residential homes.

Indirect Assessment of Implicit Disgust Sensitivity

We propose a single-block, single-target, Implicit Association Test (SB-ST-IAT) for measuring implicit disgust sensitivity. Based on dual process theories, we tested the construct validity of this new measure using a sample of N = 75 participants. Incremental validity of the newly developed SB-ST-IAT was demonstrated using a disgust sensitivity questionnaire as a direct measure of disgust sensitivity, as well as two behavioral criteria. A controlled approach versus avoidance task with disgusting stimuli (worms) was employed as a measure of controlled behavior. Facial disgust expression and withdrawal of hands and upper body from the disgust stimuli were used as indicators of automatic behavior. Implications of our research for the validation of indirect measures are discussed.

Microbes, mating, and morality: Individual differences in three functional domains of disgust.

What is the function of disgust? Whereas traditional models have suggested that disgust serves to protect the self or neutralize reminders of our animal nature, an evolutionary perspective suggests that disgust functions to solve 3 qualitatively different adaptive problems related to pathogen avoidance, mate choice, and social interaction. The authors investigated this 3-domain model of disgust across 4 studies and examined how sensitivity to these functional domains relates to individual differences in other psychological constructs. Consistent with their predictions, factor analyses demonstrated that disgust sensitivity partitions into domains related to pathogens, sexuality, and morality. Further, sensitivity to the 3 domains showed predictable differentiation based on sex, perceived vulnerability to disease, psychopathic tendencies, and Big 5 personality traits. In exploring these 3 domains of disgust, the authors introduce a new measure of disgust sensitivity. Appreciation of the functional heterogeneity of disgust has important implications for research on individual differences in disgust sensitivity, emotion, clinical impairments, and neuroscience.

Hard to handle: understanding mothers' handwashing behaviour in Ghana

While handwashing with soap (HWWS) has been identified as a major pathway to reducing the risk of diarrhoeal diseases, and respiratory infections, rates of HWWS remain low across the globe. The current study, a national survey of Ghanaian mothers, found that as few as 4% of mothers engaged in HWWS after defecation, and only 2% after cleaning a child's bottom. In a multivariate analysis, we explored the determinants of handwashing at these key junctures, with and without soap. After defecation, mother's education, knowledge of important times to handwash with soap, the age of her children, and a measure of the quality of child care were all associated with handwashing (in any form). However, only the latter two variables also predicted soap use amongst handwashers. After cleaning a child's bottom, education, knowledge of important times to handwash with soap, and child care quality were associated with handwashing (in any form), yet only one variable, a measure of disgust sensitivity, showed any possible relationship with soap use. While this study has several important limitations, failure to explain much of the observed variance, despite a large range of potential determinants explored, suggests that we need to continue complementing quantitative surveys with in-depth qualitative studies if we are to better understand the motivations for, and constraints to, HWWS in community settings.

A taxometric study of the latent structure of disgust sensitivity: Converging evidence for dimensionality.

Disgust sensitivity has recently been implicated as a specific vulnerability factor for several anxiety-related disorders. However, it is not clear whether disgust sensitivity is a dimensional or categorical phenomenon. The present study examined the latent structure of disgust by applying three taxometric procedures (maximum eigenvalue, mean above minus below a cut, and latent-mode factor analysis) to data collected from 2 large nonclinical samples on 2 different measures of disgust sensitivity. Disgust sensitivity in the first sample (n=1,153) was operationalized by disgust reactions to food, animals, body products, sex, body envelope violations, death, hygiene, and sympathetic magic, as assessed by the Disgust Sensitivity Scale (J. Haidt, C. McCauley, & P. Rozin, 1994). Disgust Sensitivity Scale indicators of core, animal reminder, and contamination disgust were also examined in the 1st sample. Disgust sensitivity in the 2nd independent sample (n=1,318) was operationalized by disgust reactions to animals, injections and blood draws, mutilation and death, rotting foods, and odors, as assessed by the Disgust Emotion Scale (R. A. Kleinknecht, E. E. Kleinknecht, & R. M. Thorndike, 1997). Results across both samples provide converging evidence that disgust sensitivity is best conceptualized as a dimensional construct, present to a greater or lesser extent in all individuals. These findings are discussed in relation to the conceptualization and assessment of disgust sensitivity as a specific dimensional vulnerability for certain anxiety and related disorders.

Attitudes Toward Women's Body Hair: Relationship with Disgust Sensitivity

We aimed to further investigate the “hairlessness” norm that is the common practice of body hair removal among women. A sample of 198 undergraduate students (91 men, 107 women) completed questionnaires asking about attitudes toward women's body hair and the reasons women remove this hair, as well as a measure of disgust sensitivity. It was found that the vast majority (98%) of female participants regularly remove their leg and/or underarm hair, most frequently by shaving, and attribute this to femininity and attractiveness reasons. However, the attributions that they and men made for other women were much more socially normative in nature. For the sample as a whole, negative attitudes toward body hair were related to disgust sensitivity. It was concluded that body hair on women, but not on men, has become an elicitor of disgust and its removal correspondingly normative.

The relation between fearfulness, disgust sensitivity and religious obsessions in a non-clinical sample

The present study sought to determine the relation among fearfulness, disgust sensitivity, and religious obsessions in a non-clinical sample. One hundred participants completed two measures of fear (Fear Survey Schedule, Padua Inventory) a measure of disgust sensitivity (Disgust Scale) and a measure of religious obsessions (Penn Inventory of Scrupulosity). Overall, the data were consistent with an additive relation among fearfulness, disgust sensitivity and religious obsessions. Inconsistent with recent notions in the research literature, the relation between disgust sensitivity and religious obsessions remained significant even after controlling for general fearfulness and cleanliness fears. Stepwise multiple regression analyses indicated that interpersonal and contamination fears as well as disgust sensitivity specifically towards sex and death best predicted religious obsessions. It is suggested that an additive model consisting of symptoms of both fear and disgust should be considered in future research and treatment of religious obsessions.

A Swedish translation and validation of the Disgust Scale: a measure of disgust sensitivity.

The psychometric properties of a Swedish version of Haidt, McCauley and Rozin's (1994) Disgust Scale were studied. Confirmatory factor analysis of the original model with eight factors (food, animals, body products, sex, body envelope violations, death, hygiene, and magic) provided satisfactory fit to the data (N= 280), significantly better than to the alternative one-factor and five-factor models. As in the US version women scored significantly higher than men. Positive correlations with measures of food neophobia (r= 0.30, p < 0.0001) and nausea frequency (rs= 0.28, p < 0.001) indicate convergent validity. In a separate study (N= 30) a behavioral measure of the willingness to touch, hold, and taste disgusting food objects correlated negatively with the Disgust Scale (r=-0.46, p < 0.01), indicating criterion-related validity.

Disgust domains in the prediction of contamination fear

Previous research has shown a relationship between the emotion of disgust and the fear of contamination. Heightened sensitivity to disgust and increased concerns over contamination has been observed in various disorders, such as obsessive–compulsive disorder (OCD) and specific phobias. However, there is a paucity of research identifying the specific domains of disgust that contribute to contamination fear. The present study soughts to determine which domains of disgust elicitors reliably predict scores on a measure of OCD contamination obsessions and washing compulsions. We further conducted exploratory analyses that examined differences in disgust sensitivity among individuals classified as high and low in contamination fear. Three hundred and twenty-three undergraduate participants completed two measures of disgust sensitivity (Disgust Scale; Disgust Emotion Scale) and a measure of contamination fear (Padua inventory, contamination obsessions and washing compulsions subscale). Stepwise multiple regression analyses indicated that contamination fear was best predicted by seven different disgust domains, thereby suggesting that contamination fear is accounted for by generalized, rather than domain-specific, disgust elicitors. The categories of disgust that predicted contamination fear appeared to have an underlying commonality of threat of contagion. The relationship between fear of contamination and disgust sensitivity was more pronounced for animal reminder disgust elicitors as opposed to core disgust elicitors. Results also showed that individuals classified as high in contamination fear scored significantly higher than the low contamination fear group on all disgust domains. Clinical and research implications regarding the interrelationships between fear, disgust, and the fear of contamination are discussed.

Disgust and fear in response to spiders

We examined disgust and fear responses to spiders in spider-distressed and nondistressed individuals. Undergraduate participants (N = 134) completed questionnaires concerning responses to spiders and other potentially aversive stimuli, as well as measures of disgust sensitivity, anxious arousal, worry, and anhedonic depression. In addition, we obtained self-report and facial expressions of disgust and fear while participants were exposed to a live tarantula. Both spider distressed and nondistressed individuals reported disgust and exhibited disgust facial expressions in response to a tarantula. Disgust in response to spiders was not found to be part of a general disgust response to all negative stimuli, nor was it due to a general negative emotional response to spiders. Emotional responses to spiders were differentially associated with scores on personality and psychological functioning measures. The results of this study provide evidence that spiders have a specific disgust-evoking status in both distressed and nondistressed populations.

Disgust sensitivity and contamination fears in spider and blood–injection–injury phobias

Disgust has been implicated in the onset and maintenance of blood–injection–injury (BII) and animal phobias. Research suggests that people with these phobias are characterized by an elevated sensitivity to disgust-evoking stimuli separate from their phobic concerns. The disgust response has been described as the rejection of potential contaminants. Disgust-motivated avoidance of phobic stimuli may therefore be related to fears of contamination or infection. The present study compared BII phobics, spider phobics and nonphobics on two measures of disgust sensitivity and two measures of contamination fears. Positive correlations were found between disgust sensitivity and contamination fear. Specific phobics scored higher than nonphobics on all scales and BII phobics scored higher than spider phobics on contamination fear measures. Furthermore, the contamination fear scales were correlated with the blood phobia measure, but not correlated with the spider phobia measure. The results suggest that while both phobias are characterized by elevated disgust sensitivity, contamination fear is more prominent in BII than spider phobia.

Disgust and eating disorders

Two studies are described which investigated the relationship between disgust sensitivity and eating disorders. In a normal sample, Study 1 found a significant correlation between measures of eating disorder and measures of disgust sensitivity, but only in female subjects. This relationship was not mediated by existing levels of anxiety or depression. Study 2 found that subjects who had clinically-diagnosed eating disorders exhibited significantly higher levels of disgust than matched normal control subjects. Both studies indicated that elevated disgust in relation to eating disorders appeared to be confined primarily to disgust of food, the body and body products, and did not extend to disgusting stimuli which are not associated with food or the body. © 1998 John Wiley & Sons, Ltd and Eating Disorders Association.
