Infection risk associated with carnivore carcasses may govern trophic interactions between maggots and insectivorous passerine birds.

Infection risk by pathogenic agents motivates hosts to avoid using resources with high risks. This, in turn, results in increased availability of these resources for other species that are more tolerant of infections. For instance, carcasses of mammalian carnivores are frequently avoided by conspecific or closely related carnivores, allowing them to be almost exclusively used by maggots. This may lead to novel interactions with other species. This study investigated the consumption of maggots from carnivore carcasses by non-corvid passerines. We successfully monitored 66 raccoon carcasses in Hokkaido, Japan, from 2016 to 2019. Vertebrates only scavenged 14 carcasses before maggot dispersal; the other 52 carcasses produced abundant maggots that regularly fed at least 12 species of non-corvid passerines. Surprisingly, predation occurred at a distance from the carcasses, mainly after maggot dispersal for pupation, despite the higher efficiency of feeding on maggot masses on the carcasses. Birds are likely to reduce the potential risk of infection from the carcass and/or from maggots on the carcasses. Overall, only 1% of maggots were consumed. Our results suggest that necrophagous flies could benefit from the infection risk associated with carnivore carcasses, which may decrease scavenging by other carnivores and constrain maggot consumption by insectivorous birds.

Conceptual-level disgust conditioning in contamination-based obsessive-compulsive disorder.

Pavlovian fear conditioning and extinction represent learning mechanisms underlying exposure-based interventions. While increasing evidence indicates a pivotal role of disgust in the development of contamination-based obsessive-compulsive disorder (C-OCD), dysregulations in conditioned disgust acquisition and maintenance, in particular driven by higher-order conceptual processes, have not been examined. Here, we address this gap by exposing individuals with high (HCC, n = 41) or low (LCC, n = 41) contamination concern to a conceptual-level disgust conditioning and extinction paradigm. Conditioned stimuli (CS+) were images from one conceptual category partially reinforced by unconditioned disgust-eliciting stimuli (US), while images from another category served as non-reinforced conditioned stimuli (CS-). Skin conductance responses (SCRs), US expectancy and CS valence ratings served as primary outcomes to quantify conditioned disgust responses. Relative to LCC, HCC individuals exhibited increased US expectancy and CS+ disgust experience, but comparable SCR levels following disgust acquisition. Despite a decrease in conditioned responses from the acquisition phase to the extinction phase, both groups did not fully extinguish the learned disgust. Importantly, the extinction resilience of acquired disgust was more pronounced in HCC individuals. Together, our findings suggest that individuals with high self-reported contamination concern exhibit increased disgust acquisition and resistance to extinction. The findings provide preliminary evidence on how dysregulated disgust learning mechanism across semantically related concepts may contribute to C-OCD.

Phase-Transitions in Disgust During Self-Initiated Eating Among Adolescents With Anorexia Nervosa and Related Low-Weight Eating Disorders and Matched Controls.

BACKGROUND: Understanding the emotional context of feeding behavior may help identify causal mechanisms of food avoidance among individuals with anorexia nervosa. Although predominant food avoidance models assume fear of fat drives feeding behavior, disgust may be more theoretically and proximally relevant to moment-to-moment experiences of feeding. This study, therefore, aimed to examine affect and food avoidance using automated affect analysis from facial response by measuring time-specific transitions in disgust during a laboratory eating paradigm. We hypothesized that phase transitions in disgust would distinguish temporally self-initiated eating from food avoidance. METHODS: Sixty-three adolescents with anorexia nervosa or another low-weight eating disorder (LWED) and 27 age- and sex-matched controls were recruited as part of a larger study; 45 patients and 22 controls provided data on autonomous eating and facial affect during a laboratory meal. Dynamic structural equation models quantified moment-to-moment relationships between disgust and feeding behavior. RESULTS: Self-initiated eating was associated with greater increases in disgust, but not fear, intensity among those with LWED relative to control participants and greater disgust intensity predicted lower likelihood of self-initiated eating. DISCUSSION: Phasic transitions in disgust provide moment-to-moment evidence of affective influence on self-initiated eating and lend credibility to the hypothesis that disgust contributes to food avoidance and initiation in individuals with LWED.

Female Affective Perception of Mainstream and Paraphilic Pornography: Associations with Sexual and Psychological Intrapersonal Variables.

Understanding affective perceptual processes can further contribute to the explanation of motivation and actions, as well as sexual risk behaviors. Pornography can be considered salient emotional content and is popular, also among females. Yet, the female perspective on pornography has often been overlooked and it remains unclear how individual variables may be associated with the affective perception of pornography and could provide a risk profile. Possible associations between several sexual and psychological intrapersonal variables and the affective perception of various forms of pornography were analyzed from the female perspective. A sample of 231 females (M = 21.87 years; SD = 3.9 years) provided ratings of affective valence, arousal, disgust, and moral and ethical acceptance for mainstream pornographic and paraphilic images of dominance, submission, or sexual violence. Paraphilic pornography was perceived as less pleasant, arousing, and moral and ethically acceptable, but more disgusting compared to mainstream pornography. This was more pronounced among females who had never consumed pornography. Results further suggest that the female affective perception of pornography was associated with the following sexual intrapersonal variables: sexual sensation seeking for physical sensations, erotophilia, lack of sexual control, problematic pornography consumption, and sexual disgust sensitivity. Of the assessed psychological intrapersonal variables, only anxiety was negatively associated with disgust for paraphilic pornography. It is important to further analyze the female affective perception of pornography and associated variables to include them in strategies for prevention and for addressing problematic consequences of the acceptance of specific sexual content and behaviors, especially related to sexualized violence.

Obsessive-Compulsive Symptomatology and Disgust Propensity in Disordered Eating Behaviors of Adolescents with Celiac Disease.

BACKGROUND: Considering the importance of underlying psychopathological mechanisms that mediate maladaptive eating behaviors in celiac disease (CD) in the determination of cognitive-behavioral therapeutic approaches, we investigated the impact of obsessive-compulsive symptomatology and disgust propensity on disordered eating attitudes (DEA) and poor gluten-free diet (GFD) compliance in adolescents with CD. METHOD: Adolescents with biopsy-proven CD (n = 148, aged 12-18 years) were compared with age- and sex-matched controls (n = 104) in terms of eating attitudes/behaviors, obsessive-compulsive symptoms, and disgust propensity, as well as depression and anxiety to rule out depression- and anxiety-related covariates. The clinical implications associated with poor GFD compliance were determined using between-subgroup analysis. Multivariate linear regression and multiple logistic regression were used to identify predictors of DEA and GFD noncompliance, respectively. RESULTS: In adolescents with CD, DEA was remarkably associated with obsessive-compulsive symptom severity and disgust propensity, especially in contamination and core disgust sub-dimensions. Obsessionality and disgust propensity were independent predictors of DEA, of which the obsessive-compulsive symptom severity was the most decisive predictor of DEA. Higher DEA severity and lower body mass index were independent predictors of poor GFD compliance. CONCLUSION: Higher obsessionality, accompanied by disgust-related evaluative conditioning processes, may contribute to constructing a cognitive network consisting of hypervigilance and catastrophic interpretations towards benign somatic stimulations, food-related preoccupations, and avoidant behaviors in the disordered eating of adolescents with CD. The reciprocal relationship between lifelong GFD and DEA, mediated by obsessionality and disgust propensity, was supported by current findings that could guide clinicians in the management of maladaptive eating behaviors in adolescents with CD.

Facing the Emotional Barriers to Colorectal Cancer Screening. The Roles of Reappraisal and Situation Selection.

BACKGROUND: Disgust, embarrassment, and fear can hinder the attendance of colorectal cancer (CRC) screening. However, individuals can respond to these emotions differently. The present study tested whether reappraising a negative stimulus versus avoiding a negative stimulus is associated with age; whether these two emotion regulation strategies (reappraisal and situation selection) moderate the effects of disgust, embarrassment and fear on CRC screening intention; and the efficacy of a message based on participants' preferred emotion regulation strategy. METHODS: We recruited 483 Italian participants (aged 40-84 years) through snowball sampling. Participants were randomly assigned to one of four conditions differing for a message promoting CRC screening with an affective lever, a cognitive lever, both levers or none. Key variables included emotion regulation strategies, emotional barriers and intention to get screened. RESULTS: The preference for reappraisal over situation selection increased with age. Reappraisal neutralized the effect of disgust on CRC screening intention. The combined message with both affective and cognitive levers increased CRC screening intention (b = 0.27, ß = 0.11, SE = 0.13 p = .049), whereas reading the message based only on the affective (b = 0.16, ß = 0.06, SE = 0.14 p = .258) or the cognitive (b = 0.22, ß = 0.09, SE = 0.14 p = .107) lever was not effective. CONCLUSIONS: Communication campaigns should support the activation of a reappraisal strategy of emotion control, and messages promoting CRC screening should highlight both the instrumental (i.e., early detection) and affective (i.e., peace of mind) benefits of attendance.

Are cooks more disgust sensitive? Preliminary examination of the food preparation hypothesis.

According to the food preparation hypothesis, sex differences in disgust sensitivity may stem from different sex roles that males and females played in our ancestral times. In current times, these differences may be reflected in varying levels of disgust sensitivity between people who frequently versus rarely engage in meal preparation, or who are versus are not professionally responsible for providing meals for others. To test this reasoning, we conducted a preregistered study with 493 individuals (55% female), with 280 of them working in the restaurant industry. Participants reported their weekly time spent on cooking-related activities and completed the Food Disgust Scale and pathogen subscale of Three Domain Disgust Scale. These measures capture specific, food-related disgust sensitivity, and generalised pathogen disgust sensitivity, respectively. We found that while time spent on cooking was not associated with disgust sensitivity, people professionally engaged in food preparation displayed higher levels of food-related disgust sensitivity. There was no effect of cooking on the generalised pathogen disgust sensitivity. Additionally, we observed sex differences in both types of disgust sensitivity and found that vegetarians exhibited lower disgust sensitivity than meat-eaters. Overall, our findings offer preliminary support for the food preparation hypothesis, and point out that the mechanisms adjusting our disgust sensitivity levels are category-specific, even within the broader pathogen disgust domain.

Four studies yield limited evidence for prepared (disgust) learning via evaluative conditioning.

Prepared learning accounts suggest that specialized learning mechanisms increase the retention of associations linked to ancestrally-prevalent threats. Few studies have investigated specialized aversion learning for pathogen threats. In four pre-registered studies (N's = 515, 495, 164, 175), we employed an evaluative conditioning procedure to test whether foods (versus non-foods) are more readily associated with negative content associated with pathogens than negative content not associated with pathogens. Participants saw negatively valenced (either pathogen-relevant or -irrelevant), neutral or positively-valenced stimuli paired with meats and plants (in Studies 1 and 2) and with meats and abstract shapes (in Studies 3 and 4). They then evaluated each stimulus explicitly via self-reports (Studies 1-4) and implicitly via an Affect Misattribution Procedure (Studies 3 and 4). Linear mixed models revealed general evaluative conditioning effects, but inconsistent evidence for specialized (implicit or explicit) learning for a food-pathogen association. However, results from a mega-analysis across studies revealed stronger conditioning effects for meats paired with pathogen-relevant negative stimuli than pathogen-irrelevant negative stimuli.

Understanding consumer attitude toward the name framings of cultured meat: Evidence from China.

The naming and labeling of products can affect consumer attitudes and subsequent behavior, particularly in the case of new food products in the market. The present study explores the effects of name framing on consumer attitudes towards cultured meat (CM), which is currently in the early stages of development. With a sample of 1532 Chinese consumers, we integrated several pathways to explain the name-framing effect by examining three different terms ("cultured," "artificial," and "cell-based") for CM. Results indicate that "cultured meat" and "cell-based meat" are more appealing than "artificial meat." Name framings of CM affect consumers' perception of benefits more than that of risks. Our comprehensive model identified evoked affect (perceived disgust) and naturalness as two crucial predictors of attitudes. These two predictors also act as substantial mediators of perceived benefits, and they activate the mediation of perceived risks (an insignificant mediator in cognitive processing). In addition, perceived naturalness mediates the name-framing effect mainly through perceived disgust. Our findings have implications for future strategies for communicating about novel foods (like CM) to the public.

Pathogen disgust sensitivity protects against infection in a high pathogen environment.

Disgust is hypothesized to be an evolved emotion that functions to regulate the avoidance of pathogen-related stimuli and behaviors. Individuals with higher pathogen disgust sensitivity (PDS) are predicted to be exposed to and thus infected by fewer pathogens, though no studies have tested this directly. Furthermore, PDS is hypothesized to be locally calibrated to the types of pathogens normally encountered and the fitness-related costs and benefits of infection and avoidance. Market integration (the degree of production for and consumption from market-based economies) influences the relative costs/benefits of pathogen exposure and avoidance through sanitation, hygiene, and lifestyle changes, and is thus predicted to affect PDS. Here, we examine the function of PDS in disease avoidance, its environmental calibration, and its socioecological variation by examining associations among PDS, market-related lifestyle factors, and measures of bacterial, viral, and macroparasitic infection at the individual, household, and community levels. Data were collected among 75 participants (ages 5 to 59 y) from 28 households in three Ecuadorian Shuar communities characterized by subsistence-based lifestyles and high pathogen burden, but experiencing rapid market integration. As predicted, we found strong negative associations between PDS and biomarkers of immune response to viral/bacterial infection, and weaker associations between PDS and measures of macroparasite infection, apparently mediated by market integration-related differences. We provide support for the previously untested hypothesis that PDS is negatively associated with infection, and document variation in PDS indicative of calibration to local socioeconomic conditions. More broadly, findings highlight the importance of evolved psychological mechanisms in human health outcomes.

Interoceptive and Affective Alterations in Body Integrity Dysphoria: An Online Self-Reporting Study.

INTRODUCTION: Body integrity dysphoria (BID) is a rare condition in which individuals experience a long-lasting desire to achieve a specific physical disability. In this study, we tested the hypothesis of interoceptive and affective abnormalities in BID, in line with the evidence of structural and functional alteration of the interoceptive-affective neural system in these individuals. METHOD: Our study involved 68 participants with BID (mean age: 35.6, SD: 16.4). Among these participants, 47 expressed a desire for amputation, 14 desired paralysis, 3 sought sensory deprivation, and 3 desired a combination of these forms. For comparisons, we recruited a control group of 79 participants (mean age: 35.2, SD: 15.8). We administered assessment measures to investigate alexithymia level (TAS-20), disgust sensitivity (DS-R), interoceptive awareness (MAIA-2), and (affective and cognitive) empathy (QCAE). We also administered the Short Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE) to identify psychiatric comorbidities. Subgroups with low O-LIFE scores (BID = 31; controls = 43) and subgroups with high O-LIFE scores (BID = 37; controls = 36) were derived through a median-split procedure. RESULTS: Within the BID low O-LIFE group, we found reduced interoceptive sensibility, reduced disgust sensitivity, and increased difficulty in identifying feelings, which refers to a dimension of the alexithymia trait. Within the BID high O-LIFE group, we observed a reduced disgust sensitivity and interoceptive sensibility, accompanied by a diminished score in cognitive empathy. CONCLUSION: Our study suggests that BID can be associated with altered interoceptive and affective processing.

Self-disgust mediates the effect of problematic mobile social media use on non-suicidal self-injury in adolescents: A latent growth curve analysis.

OBJECTIVE: Previous research linked problematic mobile social media use to non-suicidal self-injury (NSSI). However, little research explored the underlying mechanism. Drawing on the social displacement hypothesis, which suggests that excessive social media use may disrupt offline social interactions, leading to negative emotional experiences, the study employs a longitudinal design to explore the relationship between problematic mobile social media use and NSSI, with a specific emphasis on the mediating role of self-disgust. METHODS: A total of 1,684 Chinese adolescents (52.3% females; Mage = 14.59 years, SDage = 1.27) completed self-report questionnaires regarding problematic mobile social media use, self-disgust, and NSSI. The assessment was conducted in three waves, 6 months apart. RESULTS: Using latent growth curve and structural equation modeling, our study observed a consistent linear decline in NSSI levels over time. Higher initial NSSI levels correlated with a slower reduction. Problematic mobile social media use positively influenced the initial level of NSSI. Additionally, self-disgust played a mediating role in the relationship between problematic mobile social media use and NSSI. CONCLUSIONS: The study underscores the importance of understanding the emotional experiences behind social media use, beyond mere usage duration. By revealing the mediating role of self-disgust, it provides new insights into the complex interplay between problematic mobile social media use and adolescent NSSI.

Contamination in Trypophobia: investigating the role of disgust.

Trypophobia is a relatively common aversion to clusters of holes. There is no consensus yet on which emotions are involved in Trypophobia nor in its functional utility. This report investigates the role of disgust using contamination tasks in two studies, which contrast people with an aversion to trypophobic stimuli to those without. In Study 1, participants reported their emotional reactions to imagined contamination of trypophobic images. In Study 2, participants evaluated physically present trypophobic, disgust, fear, and control stimuli. The capacity of these stimuli to contaminate other objects was established using a chain of contagion task. Across both studies, contamination was present, however, only those with an aversion to trypophobic stimuli evidenced contamination on the chain of contagion task, a hallmark of disgust responding. Elevated levels were not only reported for disgust, but also alongside fear/anxiety. Participant reports suggest an underlying disease avoidance mechanism in Trypophobia, with trypophobic participants demonstrating an exaggerated response to such stimuli involving disgust and fear/anxiety, which is also seen in small animal phobia, BII, and C-OCD. Implications, particularly for treatment are discussed.

Age-related disgust responses to signs of disease.

Previous studies found similarities in adults' disgust responses to benign (e.g. obesity) and actual disease signs (e.g. influenza). However, limited research has compared visual (i.e. benign and actual) to cognitive (i.e. disease label) disease cues in different age groups. The current study investigated disgust responses across middle childhood (7-9 years), late childhood (10-12 years), adolescence (13-17 years), and adulthood (18+ years). Participants viewed individuals representing a benign visual disease (obese), sick-looking (staphylococcus), sick-label (cold/flu), and healthy condition. Disgust-related outcomes were: (1) avoidance, or contact level with apparel the individual was said to have worn, (2) disgust facial reactions, and (3) a combination of (1) and (2). Avoidance was greater for the sick-looking and sick-label than the healthy and obese conditions. For facial reaction and combination outcomes, middle childhood participants responded with greater disgust to the sick-looking than the healthy condition, while late childhood participants expressed stronger disgust towards the sick-looking and obese conditions than the healthy condition. Adolescents and adults exhibited stronger disgust towards sick-label and sick-looking than obese and healthy conditions. Results suggest visual cues are central to children's disgust responses whereas adolescents and adult responses considered cognitive cues.

Association between Disgust Sensitivity during Pregnancy and Endogenous Steroids: A Longitudinal Study.

The emotion of disgust protects individuals against pathogens, and it has been found to be elevated during pregnancy. Physiological mechanisms discussed in relation to these changes include immune markers and progesterone levels. This study aimed to assess the association between steroids and disgust sensitivity in pregnancy. Using a prospective longitudinal design, we analyzed blood serum steroid concentrations and measured disgust sensitivity via text-based questionnaires in a sample of 179 pregnant women during their first and third trimesters. We found positive correlations between disgust sensitivity and the levels of C19 steroids (including testosterone) and its precursors in the Δ5 pathway (androstenediol, DHEA, and their sulfates) and the Δ4 pathway (androstenedione). Additionally, positive correlations were observed with 5α/ß-reduced C19 steroid metabolites in both trimesters. In the first trimester, disgust sensitivity was positively associated with 17-hydroxypregnanolone and with some estrogens. In the third trimester, positive associations were observed with cortisol and immunoprotective Δ5 C19 7α/ß-hydroxy-steroids. Our findings show that disgust sensitivity is positively correlated with immunomodulatory steroids, and in the third trimester, with steroids which may be related to potential maternal-anxiety-related symptoms. This study highlights the complex relationship between hormonal changes and disgust sensitivity during pregnancy.

Anxiety sensitivity and disgust sensitivity predict blood-injection-injury fears in individuals with dental anxiety.

BACKGROUND: Anxiety sensitivity (AS) and disgust sensitivity (DS) are transdiagnostic vulnerability factors for anxiety. Both correlate with blood-injection-injury (BII) phobia symptoms in several studies; however, there is ambiguity about their relative contributions, and studies investigating this have relied on unselected samples. Furthermore, although DS reliably predicts BII in studies that do not account for AS, this may be limited to domain-specific DS rather than DS more broadly. AIMS: The aims of this study were to examine AS and DS as separate and simultaneous predictors of BII fears in a sample with a wide range of BII symptoms, and with attention to the specificity of DS to BII-relevant domains. METHOD: Fifty-three participants who scored above a clinical threshold on a validated measure of dental anxiety, and who represented a wide range of BII severity, completed measures of AS, DS and BII symptoms. RESULTS: AS and DS were moderately to strongly correlated with BII severity (r = .40 and .47, p = .004 and <.001), and both independently predicted BII severity when entered as simultaneous predictors (ß = .32 and .35, p = .045 and .015). Furthermore, after omitting DS about injections and blood draws, domain-general DS was still moderately correlated with BII severity (r = .33, p = .017). However, domain-general DS did not significantly predict BII severity after accounting for AS (ß = .20, p = .164). CONCLUSIONS: AS and DS both predict BII symptoms, and prospective research is warranted to examine them as potential vulnerability factors.

Disgust as a basic, sexual, and moral emotion.

Disgust is a basic emotion that increases the organism's survival success by preventing the transfer of pathogens. In this regard, it directs cognitive processes and motivates avoidance behaviors that prevent pathogens from entering the body. Moreover, disgust has many specific characteristics that distinguish it from other basic emotions. Firstly, unlike other basic emotions, it contaminates neutral objects around it and causes difficult-to-change learning. Another specific characteristic of disgust is that it depends on ideational processes. Objects, situations, and behaviors that do not contain pathogens can also cause disgust. In this regard, disgust appears not only as a basic emotion but also as different adaptations in different fields. In this context, two distinct adaptations of disgust stand out: sexual and moral disgust. These two adaptations of disgust benefit from disgust-related behaviors and motivations in different ways. Sexual disgust works as a gene protection mechanism, while moral disgust helps maintain social rules. The specific characteristics of disgust and its effects on cognitive processes such as attention and memory interact. In conclusion, the multifaceted structure of disgust shows that it needs to be studied more in the subfields of psychology. (Strohminger, Philos Compass 9:478-493, 2014) defines disgust as a psychological nebula that needs to be discovered. However, it is observed that disgust has not been adequately addressed. This review aims to comprehensively explore unique characteristics and diverse aspects of disgust, shedding light on its significance from various perspectives. This study underscores the broader understanding of disgust and its pivotal role in psychological research.

Visual images of disgusting creatures facilitated attentional orienting and delayed attentional disengagement.

Numerous studies have suggested that threatening stimuli induce a spatial attention bias; however, only a few studies have investigated spatial attention biases for disgusting stimuli. Moreover, past studies generally reported that the spatial attention bias to disgusting images is not robustly in normal individuals. We hypothesized that this was due to the unfamiliar of the images, so we prepared the creature's images that were clearly categorized as disgusting and examined the effects of disgusting images on spatial attention bias. A disgusting or an emotionally neutral image was paired and presented with an (emotionally neutral) filler image. After a temporal interval, a target appeared at either the position where a disgusting or a neutral image was presented (valid condition) or where a filler image was presented (invalid condition). Participants pressed a key corresponding to the target's position as quickly and accurately as possible. We varied the position-response correspondence among three experiments. The results showed that the RTs in the invalid condition was longer for the disgusting images than for the neutral images when the position of a disgusting image was not naturally associated with the left-right hand position. We interpreted the results in that that disgusting images generally slowed down attentional disengagement process but the manual responses were inhibited for the position where a disgusting image appeared when the locations of keys and targets were congruent. The present results suggest that disgusting images affect not only attentional processes but also manual responses related to the selection and initiation of responses.

Longitudinal Associations Between Negative Body Image, Self-Disgust, and Nonsuicidal Self-Injury Among Chinese Adolescents: Disentangling Between- and Within-Person Effects.

Nonsuicidal self-injury (NSSI) and negative body image are both highly prevalent among adolescents, and there are theoretically proposed reciprocal associations between them. However, previous research has not differentiated between stable personal traits and time-varying state levels when examining these associations, and the underlying mechanisms remain unclear. To address these gaps, this study investigated the longitudinal associations between negative body image, self-disgust, and NSSI among Chinese adolescents, disentangling the between- and within-person effects by employing random intercept cross-lagged panel models (RI-CLPMs). A total of 515 Chinese adolescents (50.7% boys; baseline Mage = 12.34 years, SD = 0.47) participated in a four-wave longitudinal study with 6-month intervals. The results indicated that, at the between-person level, higher levels of self-disgust were associated with more NSSI and more concerns about general appearance, facial appearance, shortness, and fatness, but were not associated with concerns about thinness. At the within-person level, general appearance concern and NSSI positively predicted each other over time through self-disgust. Concerns about facial appearance, shortness, and fatness all positively predicted self-disgust, which in turn positively predicted NSSI over time, but not vice versa. These findings highlight the stable and trait-like associations between self-disgust, NSSI, and most negative body image dimensions. Self-disgust is worth considering as a target for intervention, as it plays a mediating role in the long-term associations between negative body image and NSSI.

The identification of the relationship between nursing students' disgust sensitivity and willingness to care for the elderly: The case of a university.

OBJECTIVES: In clinical learning environments, nursing students frequently encounter situations that cause physical disgust. It is believed that a high sensitivity to disgust among students can negatively affect their academic performance and caregiving behavior. This study was conducted to identify the relationship between nursing students' disgust sensitivity and willingness to care for older adults. METHOD: This descriptive and cross-sectional research was conducted with 807 volunteer participants studying at the Department of Nursing of a university in southeast Turkey. The research data were collected by using the Personal Information Form, the Disgust Sensitivity Scale - Revised Form (DS-R), and the Willingness to Care for the Elderly Scale (WCES) . Descriptive statistics, the Student's t-test, the Mann-Whitney U test, the One-Way Analysis of Variance, and Pearson's correlation were used in the analysis of research data. RESULTS: In the research, nursing students' mean DS-R and WCES scores were calculated respectively as 77.93 ± 16.40 and 34.16 ± 5.98 points. A statistically significant negative relationship was found between nursing students' DS-R and WCES scores (p < 0.05). In the research, there were statistically significant differences in nursing students' mean DS-R scores as per the variables of student gender and class year. Also, it was found that, as per the variables of student nationality and the status of assuming responsibility for the care of a sick or old relative, there were statistically significant differences in both nursing students' mean DS-R scores and their mean WCES scores (p < 0.05). CONCLUSION: It was concluded that nursing students had high-level disgust sensitivity and medium-level willingness to care for an older adult. As the disgust sensitivity of the nursing students increased, their willingness to care for an older adult was negatively affected. Therefore, it is important that nurse educators evaluate nursing students' disgust sensitivity and help nursing students define and eliminate their disgust emotions.
