Abstract
Research has identified trait sensitivity as a potential risk factor and treatment target of eating disorders. Conceptualizations of trait sensitivity have depicted individuals with high and low trait sensitivity metaphorically as orchids and dandelions, highlighting their responsiveness to environmental conditions and associated outcomes. While orchids require careful tending to survive, with such care, they emerge extraordinary. In contrast, dandelions can survive a broad range of environmental conditions. Within a scientific framework, trait sensitivity can be conceptualized as neurobiologically-based, with heightened sensory, interoceptive, interpersonal, and emotional processing. While trait sensitivity may increase susceptibility to eating disorders, when therapists view these traits through the lens of environmental responsiveness, they can facilitate their client's inherent resilience and potential. Incorporating a model of trait sensitivity into eating disorders treatment using psychoeducation, modifying environmental stimuli, and selecting optimal interventions has the potential to increase treatment engagement, deepen therapeutic collaboration, and improve outcomes.

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
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.

Autistic traits, sensory sensitivity and eating disturbances in a sample of young adults referring to a generalized mental health clinic. Eat Weight Disord 2024; 29:10.

Abstract
PURPOSE The relationship between autistic traits and eating disturbances has been given considerable attention over the last decades. The rise of a dimensional approach to psychopathology has expanded the way we think about autism, acknowledging that subthreshold autistic manifestations span across the general population and are more pronounced in psychiatric patients. Here we investigated the prevalence of eating disorders and its potential relationship with autistic traits and sensory sensitivity in a group of patients who were referred for the first time to a mental health outpatient clinic, without a formal diagnosis yet. METHODS 259 young adults (between 18 and 24 years old) completed: the Eating Attitude Test (EAT-26), the Swedish Eating Assessment for Autism Spectrum Disorders (SWEAA), the Autism Quotient (AQ), the Ritvo Autism Asperger Diagnostic Scale-Revised (RAADS-R), and the Sensory Perception Quotient-Short Form 35 item (SPQ-SF35). RESULTS 23.55% of participants scored above the cut-off at the EAT-26, suggesting that they presented a risk for eating disorders and should be assessed by a specialized clinician; associations emerged between hypersensitivity in the touch and vision domain and both the EAT-26 and the SWEAA; the presence of autistic traits was largely associated with eating disturbances. CONCLUSIONS This study underlines the significance of the eating domain as a central psychopathological feature in the distress experienced by young adults with general psychiatric symptoms and psychological suffering; it adds evidence to the association between autistic traits and eating disorders and opens to new research questions about the role of subthreshold autistic traits in general psychopathology. LEVEL OF EVIDENCE Level I: Evidence obtained from experimental studies.

Abstract
Research on suicidality in muscle dysmorphia is limited despite the high rates of suicidal thoughts and behaviors in related disorders. This study employed network analysis to examine the longitudinal relationships between muscle dysmorphia symptoms, as well as the relations between MD symptoms and suicide risk factors. Fifty individuals (Mage = 30.6 years, 63 % male) meeting criteria for muscle dysmorphia received four daily surveys for three weeks. Multi-level vector autoregression analysis was used to estimate associations between muscle dysmorphia- and suicide-related thoughts, emotions, and behaviors. The most central nodes in the muscle dysmorphia networks related to assessing muscle size, dieting, using muscle-building supplements, experiencing body dissatisfaction, seeking reassurance, and avoiding others due to concerns about appearance. In the comorbidity networks, the most central suicide-related factors were feelings of burdensomeness, feeling disgusted, and dwelling on the past. Our findings indicated that various intrusive thoughts (body dissatisfaction, dieting), compulsions (seeking reassurance, body checking, supplement use), and beliefs (burden to others, disgust with oneself) predicted future engagement in muscle dysmorphia and suicide-related symptomology. Targeting intrusive thoughts and compulsions, as well as feelings of disgust and burdensomeness, may reduce the severity of these conditions.

Abstract
Self- disgust is an adverse self-conscious emotion that plays an important role in psychopathology and well-being. However, self-disgust has received little attention in the emotion literature, therefore our understanding of the processes underlying the experience of self-disgust is relatively scarce, although neuropsychological and neuroimaging studies support the idea that this emotion may heavily rely on frontal lobe-related cognition. To test this hypothesis, in two studies we investigated the relationship between state and trait levels of self-disgust, cognition and emotion regulation in healthy adults. Specifically, in Study 1 we tested the hypothesis that emotion regulation strategies (avoidance, suppression, and cognitive reappraisal) mediate the relationship between inhibition ability and state and trait levels of self-disgust. In Study 2, we followed a more comprehensive approach to test the hypothesis that frontal lobe-related cognitive processes (updating, Theory of Mind-ToM-, and self-attention) are closely related to the experience of self-disgust in healthy adults. Overall, across these studies, we found evidence to support the idea that inhibition ability and ToM may play a role in the experience of state and trait self-disgust, respectively. However, we did not find consistent evidence across the two studies to support the notion held in the literature that the experience of self- conscious emotions, in this case self-disgust, is heavily dependent on frontal lobe-related cognition.

Abstract
OBJECTIVE Food-related anxiety and avoidance are key features of anorexia nervosa, and among the most arduous maintaining processes to address in treatment. This study gathered information on the behavioural and cognitive correlates of food-related anxiety, including their associations with early experiences of aversive learning related to food, and more general anxiety. METHODS One-hundred and forty-four patients with anorexia nervosa were recruited from clinical services in Italy. They completed online questionnaires to assess food-related anxiety, eating disorder psychopathology, eating disorder safety behaviours and threat cognitions, early experience of aversive learning related to food, and somatic anxiety. RESULTS Experiences of food-related aversive learning were recalled by the majority of the sample (87.86%), with negative psychological consequences following eating being the most often reported (75%). Safety behaviours and threat cognitions related to the consequences of eating were also reported (14.29%-87.86%, and 36.43-90% respectively, depending on the behaviour/cognition). Eating disorder psychopathology was predicted by both somatic anxiety and negative psychological consequences following eating, whereas self-reported food anxiety was only predicted by somatic anxiety. CONCLUSION Findings validate an anxiety-based model of anorexia nervosa which establishes the role of safety behaviours, threat cognitions, early aversive learning experiences, and anxiety in the psychopathology of the illness. Exposure-based interventions have the potential to target these factors, and inhibit food-related fear.

Abstract
Background Ovarian hormones play a critical role in emotion processing, which may be a major reason for the high rates of major depressive disorders in women. However, the exact roles of estradiol and progesterone in emotional processing remain unclear. To this end, we performed behavioral and rs-fMRI studies on the effects ovarian hormones on disgust emotion. Methods In Experiment 1, 95 Chinese female undergraduates completed the single category implicit association test (SC-IAT) and explicit measures of disgust intensity task, 32 in the menstrual phase, 30 in the follicular phase, and 33 in the luteal phase. In Experiment 2, A total of 25 healthy female undergraduates completed three sessions of the rs-fMRI. The menstrual group was scanned during cycle days 2-5, the follicular group during cycle during days 10-13, and the luteal group was scanned 3-7 days before the next menstruation. Results The behavioral results showed that women during the luteal phase had higher D scores and shorter response times (RTs) to disgust stimuli compared to the menses and follicular phases. In contrast, women during the follicular phase had fewer feelings of disgust and longer RTs to pathogen stimuli compared with that during the menses and luteal phases, but this effect was moderated by the intensity of the stimuli. rs-fMRI studies showed that women during the luteal phase have higher functional connectivity in the salience network than those in the follicular phase. Compared with the menstrual phase, women have lower functional connectivity in the amygdala during the follicular phase. Conclusion In summary, a more negative attitude to disgust stimuli and the enhanced functional connectivity of the salience network during the luteal phase may be associated with high progesterone levels, whereas lower disgust feelings and reduced functional connectivity of the amygdala during the follicular phase may be associated with high estradiol levels.

Abstract
Individual differences exist in perceived vulnerability to disease (PVD). PVD is associated with negative responses (e.g., disgust) towards individuals with obesity and heightened sensitivity regarding personal appearance. Through increasing fear of fat (FOF), PVD may be associated with cognitive restraint and compensatory behaviors. We utilized an adult sample (n = 247; 53.3% male sex assigned at birth) recruited through Amazon's MTurk prior to the COVID-19 pandemic to investigate associations between PVD, cognitive restraint and compensatory behaviors. Participants completed the Perceived Vulnerability to Disease Scale, Eating Disorder Diagnostic Scale, Dutch Eating Behaviors Questionnaire, and Goldfarb's Fear of Fat Scale. Mediation analyses were used to test our hypotheses. Perceived infectability (PVD-Infection) was associated with cognitive restraint and compensatory behaviors through increased FOF. Perceived germ aversion (PVD-Germ) was associated with cognitive restraint, but FOF did not mediate this association. Sex-stratified analyses revealed no significant sex differences. PVD may be an overlooked factor associated with cognitive restraint and compensatory behaviors in males and females. FOF was an important mediating factor in these associations. Increased engagement in cognitive restraint and compensatory behaviors may reflect attempts to reduce FOF. Future longitudinal research should explore whether PVD is a risk factor for cognitive restraint and compensatory behaviors.

Abstract
Disgust and self-disgust are aversive emotions which are often encountered in people with eating disorders. We conducted a systematic review and meta-analysis of disgust and self-disgust in people with eating disorders using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The systematic review of the literature revealed 52 original research papers. There was substantial heterogeneity regarding the research question and outcomes. However, we found 5 articles on disgust elicited by food images, 10 studies on generic disgust sensitivity, and 4 studies on self-disgust, and we proceeded to a meta-analytic approach on these studies. We found that women with eating disorders have significantly higher momentary disgust feelings in response to food images (1.32; 95% CI 1.05, 1.59), higher generic disgust sensitivity (0.49; 95% CI 0.24, 0.71), and higher self-disgust (1.90; 95% CI 1.51, 2.29) compared with healthy controls. These findings indicate the potential clinical relevance of disgust and self-disgust in the treatment of eating disorders.

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
Fear is central to conceptualizations of weight and shape-focused eating disorders. The current study will examine the reliability and validity of a test meal paradigm that varies perceptions of fat content to manipulate fear. Undergraduate women with elevated eating pathology (N = 96) will be randomized to one of three test meal conditions: two "low" fat yogurts, two "high" fat yogurts, or one "high" fat and one "low" fat yogurt. In actuality, all yogurts will have the same fat content. Supporting reliability, we hypothesize that self-reported fear and electrodermal activity (psychophysiological index of fear-related arousal) will exhibit good test-retest reliability over a 48-hr period in the "high" fat/"high" fat and "low" fat/"low" fat conditions. Supporting construct validity, self-reported fear and electrodermal activity will be elevated during the "high" versus "low" fat condition and responses to the "high" fat condition will correlate with fear of food, eating, and weight gain. Supporting discriminant validity, self-reported disgust and anger will be comparable in the "high" and "low" fat conditions and will exhibit weak correlations with trait measures of disgust and anger. This experimental paradigm will allow researchers to manipulate fear in order understand the mechanisms by which fear maintains eating pathology.

Abstract
Mindfulness is a two-component skill that includes mindful awareness (attentional monitoring of present moment experience) and mindful acceptance (adopting an attitude of acceptance toward this experience). Although mindfulness-based interventions (MBIs) are efficacious for many conditions, there is a lack of research on MBIs for eating disorders (EDs). We propose that MBIs may be promising for EDs given their potential to mobilize not one, but multiple associative-learning change mechanisms in EDs-defined as adaptive processes of change involving one of two forms of associative-learning: Pavlovian and operant learning. We hypothesize how MBIs-via increasing either mindful awareness or mindful acceptance-may mobilize up to eight associative-learning change mechanisms, two involving Pavlovian learning, and six involving operant learning. We also elaborate on similarities and differences between MBIs and CBT approaches for EDs, as well as opportunities for synergy. Finally, we present recommendations for future research related to the development and evaluation of novel MBI interventions for EDs and the testing of mechanisms and patient-treatment matching hypotheses.
