Abstract
OBJECTIVE Eating disorders (EDs) represent a rising global health concern. The current study takes a multivariate approach to examine psychological (i.e., perfectionism, anxiety sensitivity [AS], emotion dysregulation) and sociocultural factors (i.e., body dissatisfaction) that may relate to risk and resilience in EDs. METHODS Participants were 698 undergraduate students (Mage = 21, SDage = 4.02), mainly female (71%) and Hispanic (61.6%), who participated in an online survey assessing perfectionism, emotion dysregulation, AS, body dissatisfaction, and eating behaviors. RESULTS The results from structural equation model analyses revealed differential associations with disordered eating (DE) outcomes. Self-oriented perfectionism and dysmorphic appearance concerns were associated with increased dieting/carb restriction, desire for thinness, and binging tendencies. Specifically, emotional nonacceptance and lack of emotional awareness showed associations with elevated risk for dieting/carb restriction and purging tendencies, respectively. Conversely, lack of emotional clarity showed a protective pathway to these risk behaviors. Anxiety sensitivity cognitive concerns related to higher purging tendencies, while AS social concerns related to lower purging and binging tendencies. DISCUSSION Findings highlight the differential pathways of psychosocial risk and resilience for EDs. Subscales of emotional dysregulation and AS showed risk as well as resilience associations with DE outcomes. This information is key for advancing transdiagnostic prevention and intervention to reduce the rising rates of EDs.

Abstract
Background Eating disorder (ED) subtyping studies have often extracted an undercontrolled, an overcontrolled and a resilient profile based on trait impulsivity and perfectionism. However, the extent to which methodological choices impact the coherence and distinctness of resulting subtypes remains unclear. Objective In this paper, we aimed to assess the robustness of these findings by extracting personality-based subtypes on a sample of ED patients (N = 221) under different analytic conditions. Methods We ran four latent profile analyses (LPA), varying the extent to which we constrained variances and covariances during model parametrization. We then performed a comparative analysis also including state ED symptom measures as indicators. Finally, we used cross-method validation via k-means clustering to further assess the robustness of our profiles. Results Our results demonstrated a four-profile model based on variances in impulsivity and perfectionism to fit the data well. Across model solutions, the profiles with the most and least state and trait disturbances were replicated most stably, while more nuanced variations in trait variables resulted in less consistent profiles. Inclusion of ED symptoms as indicator variables increased subtype differentiation and similarity across profiles. Validation cluster analyses aligned most with more restrictive LPA models. Conclusion These results suggest that ED subtypes track true constructs, since subtypes emerged method-independently. We found analytic methods to constrain the theoretical and practical conclusions that can be drawn. This underscores the importance of objective-driven analytic design and highlights its relevance in applying research findings in clinical practice.

Abstract
OBJECTIVE Bulimia nervosa (BN) is associated with loss-of-control (LOC) eating episodes that frequently occur in response to negative emotions. According to recent neurocomputational models, this link could be explained by a failure to accurately update beliefs about the body in states of high arousal. Specifically, these interoceptive inference models suggest that under-relying on signals from one's body about sensory experience ("low sensory precision") and/or over-relying on previously held beliefs ("excessively precise priors") lead to inaccurate perception and maladaptive behaviors. We conducted an initial test of these core predictions of the interoceptive inference model in BN using self-report measures. METHODS We compared women with BN (n = 30) and age-, BMI-, and full-scale IQ-matched controls (n = 31) on trust in sensory information from the body and two types of beliefs about what can be done to regulate high negative affect. Within the BN group, we tested interrelations among these measures and explored their associations with LOC eating frequency. RESULTS Compared with healthy controls, the BN group reported lower levels of trust in sensory information and stronger beliefs that once upset, there is little one can do, apart from eating, to self-regulate. These beliefs were associated with each other and with lower body trust. Beliefs about the uncontrollability of emotion were associated with more frequent subjective binge-eating episodes. CONCLUSIONS Findings provide initial support for the core predictions of an interoceptive inference account of BN: low trust in sensory information ("sensory precision") may promote an overreliance on maladaptive "prior beliefs" about the effects of eating on negative emotions, ultimately interfering with accurate updating of beliefs about other strategies that could regulate emotions and maintain LOC eating. Low body trust, strong expectations about emotions, and their neurocomputational underpinnings could be promising combined treatment targets for BN.

Pre-operative body shape concerns moderate excess weight loss trajectory in bariatric surgery patients: a 2-year longitudinal study. Eat Weight Disord 2024; 29:30.

Abstract
PURPOSE The main research aim was to inspect whether pre-operative body shape concerns and discomfort as Body Shape Questionnaire (BSQ) scores moderate post-operative weight loss trajectory in bariatric patients. METHODS Two studies were conducted. Study 1 analyzed cross-sectional data and verified the structural validity of the 34-item BSQ questionnaire on a sample of 327 candidates for bariatric surgery. Study 2 examined longitudinal data, with objective Body Mass Index (BMI) recorded every 6 months, from surgery intervention on, with 5 measurement occasions, from 111 patients who initially completed BSQ as bariatric surgery candidates and then underwent periodic medical post-operative follow-ups, over 2 years. RESULTS In Study 1, confirmatory factor analysis of a single-dimension model yielded acceptable fit indices and high internal consistency levels. Study 2 showed that post-operative excess BMI reduction trend was not linear and pre-operative BSQ scores moderated it, with a higher risk of weight regain in patients who initially were less concerned with their body shape. CONCLUSIONS The present findings support the structural validity of the BSQ questionnaire in bariatric candidates and call attention on the role of pre-operative body shape concerns on post-operative weight loss trajectories over 2 years, in accordance with a pathoplasty model. They suggest the need for systematic attention on perceived body image and psychological paths aimed to help bariatric patients regain positive attitudes towards their own body. Level of evidence III, well-designed cohort.

Abstract
Disturbances in eating behaviours and differences in personality characteristics, such as perfectionism, cognitive flexibility, and obsessive-compulsive behaviours, are commonly reported in individuals with eating disorders (ED) and can influence the development and maintenance of EDs. The presence of these characteristics in ED professionals may also have an influence on their patients. The aim of this study was to gain a better understanding of the presence of these behaviours and characteristics in ED clinicians/researchers (EDCR). This study examined whether these constructs differed amongst 83 EDCR and 47 general mental health clinicians/researchers (MHCR), who completed an online survey, measuring eating disorder symptomology, orthorexia nervosa, perfectionism, cognitive flexibility, and obsessive-compulsive traits. Significantly less dietary restraint, eating concerns and orthorexia nervosa behaviours, but significantly poorer ability to seek out alternative solutions (i.e. a component of cognitive flexibility) were found in the EDCR group compared with the MHCR group. Moderation analysis found no effect of ED history on the relationship between eating behaviours and group. These results suggest that working in the ED field may be a protective factor against developing certain disordered eating behaviours. However, poorer cognitive flexibility may adversely impact EDCRs, and should be considered when carrying out their clinical and/or research duties.

Abstract
Eating disorders (EDs) have been understudied and misunderstood in men. Among the relevant factors in the risk, onset, and maintenance of EDs, personality stands out. Therefore, the aim of the study was to analyze the relationships between personality traits and risk variables for the development of EDs in men. A total of 443 male university students (mean = 22.16 years) who completed the Spanish versions of the Eating Disorder Inventory-3 (EDI-3) and the NEO Five-Factor Inventory (NEO-FFI) participated. Correlation analyses were performed, and in order to determine the predictive role of personality traits on risk scales, a hierarchical multiple regression was performed. The results showed that neuroticism was positively associated with drive for thinness, being its main predictor variable. In bulimia, the main relationships were positively associated with neuroticism and negatively with conscientiousness. As for body dissatisfaction, the main predictor variables were neuroticism and, in a negative sense, extraversion and openness to experience. In conclusion, personality traits are related to the risk of developing EDs in male university students, with neuroticism being the main associated trait.

Abstract
OBJECTIVE Previous studies have revealed associations between disordered eating symptoms, big-five personality traits, and psychological distress. However, limited research has explored these relationships as a network, including their interconnections, and even less has done so in non-Western populations. We employed network analysis to investigate the co-occurrence of disordered eating symptoms, big-five personality traits, and psychological distress in Chinese adults. METHOD A sample of 500 Chinese adults (256 men) completed measures assessing big-five personality traits, psychological distress, and disordered eating symptoms. The network of personality traits, psychological distress, and disordered eating symptoms was estimated, including its central and bridge nodes. RESULTS The central nodes in the network were the facets of openness (like adventure), extraversion (like going to social and recreational parties), and disordered eating symptoms (dissatisfaction with body weight or shape). Moreover, certain facets of neuroticism (always worrying something bad will happen), psychological distress (feeling worthless), and an inverse facet of extraversion (bored by parties with lots of people) were identified as essential bridge nodes in maintaining the structure of the network. CONCLUSION Our findings suggest that personality traits (e.g., openness and extraversion) and body dissatisfaction are important in maintaining the network in a community sample of Chinese adults. While future replication is needed, findings from this study suggest that individuals with negative self-thinking, predisposed neuroticism, and extraversion may be at risk of developing disordered eating symptoms. PUBLIC SIGNIFICANCE The present study contributes to existing knowledge by employing a network perspective to examine the associations between disordered eating symptoms, big-five personality traits, and psychological distress in a Chinese adult community sample. The identified facets of neuroticism and extraversion and symptoms of psychological distress may be worthy of targeting in the prevention and treatment of disordered eating in the Chinese context.

Abstract
OBJECTIVE The aim of this study was to investigate the relationships between personality dimensions, coping strategies, and Hikikomori while controlling for the presence of depression and anxiety. METHODS Two groups, recruited on social networks, were compared: the control group (n=101, mean age±standard deviation [SD]= 36.2±12.8 years) and the Hikikomori group (n=28, mean age±SD=30.1±9.1 years). Participants of both groups completed the Big Five Inventory, the Brief Coping Orientation to Problems Experienced, and the Hospital Anxiety and Depression Scale. RESULTS The Hikikomori group had higher depression, anxiety, neuroticism, and dysfunctional coping dimension (self-blame and behavioral disengagement) scores than the control group. Being alone and depression were positively associated with Hikikomori while extraversion and instrumental support were negatively associated with Hikikomori. CONCLUSION These findings contribute to a better understanding of the psychological functioning of Hikikomori as well as to treatment elaboration and confirm that some psychological characteristics are transcultural.

Abstract
This comprehensive narrative review explores the concept of neuro-vulnerability in energy metabolism regulation and its implications for metabolic disorders. The review highlights the complex interactions among the neural, hormonal, and metabolic pathways involved in the regulation of energy metabolism. The key topics discussed include the role of organs, hormones, and neural circuits in maintaining metabolic balance. The review investigates the association between neuro-vulnerability and metabolic disorders, such as obesity, insulin resistance, and eating disorders, considering genetic, epigenetic, and environmental factors that influence neuro-vulnerability and subsequent metabolic dysregulation. Neuroendocrine interactions and the neural regulation of food intake and energy expenditure are examined, with a focus on the impact of neuro-vulnerability on appetite dysregulation and altered energy expenditure. The role of neuroinflammation in metabolic health and neuro-vulnerability is discussed, emphasizing the bidirectional relationship between metabolic dysregulation and neuroinflammatory processes. This review also evaluates the use of neuroimaging techniques in studying neuro-vulnerability and their potential applications in clinical settings. Furthermore, the association between neuro-vulnerability and eating disorders, as well as its contribution to obesity, is examined. Potential therapeutic interventions targeting neuro-vulnerability, including pharmacological treatments and lifestyle modifications, are reviewed. In conclusion, understanding the concept of neuro-vulnerability in energy metabolism regulation is crucial for addressing metabolic disorders. This review provides valuable insights into the underlying neurobiological mechanisms and their implications for metabolic health. Targeting neuro-vulnerability holds promise for developing innovative strategies in the prevention and treatment of metabolic disorders, ultimately improving metabolic health outcomes.

Abstract
Introduction The Personality Inventory for DSM-5 (PID-5) is a self-report measure of personality pathology designed to measure pathological personality traits outlined in the DSM-5 alternative model of personality disorders. Within the extensive literature exploring the relationship between personality and disordered eating, there are few that explore the relationship between the PID-5 and disordered eating behaviours in a non-clinical sample of males and females: restrictive eating, binge eating, purging, chewing and spitting, excessive exercising and muscle building. Methods An online survey assessed disordered eating, PID-5 traits and general psychopathology and was completed by 394 female and 167 male participants aged 16-30. Simultaneous equations path models were systematically generated for each disordered eating behaviour to identify how the PID-5 scales, body dissatisfaction and age predicted behaviour. Results The results indicated that each of the six disordered behaviours were associated with a unique pattern of maladaptive personality traits. The statistical models differed between males and females indicating possible differences in how dimensional personality pathology and disordered eating relate. Discussion It was concluded that understanding disordered eating behaviour in the context of personality pathology may assist formulating potentially risky behaviour.

Abstract
Introduction Previous research has highlighted the putative role of intrasexual competition (IC) in predicting women's body dissatisfaction, weight loss effort, and, at its extreme, eating disorders. However, extant research reporting on these links is limited by its exclusion of potential confounds, including psychopathologies such as depression. Moreover, it is presently unclear whether women higher in body mass index (BMI) may be more prone to the influence of IC in taking dieting risks. Methods To address these gaps in the literature, 189 young adult women completed measures of IC, depressive symptoms, willingness to use a risky diet pill, and had their height and weight measured. Results Results showed that IC interacted with BMI to predict willingness to use a risky diet pill, such that women high in both IC and BMI were most likely to take the risky diet pill. Further exploratory analyses considering potential directional links between BMI and depression supported mediating roles of depression (from BMI) and BMI (from depression) in predicting willingness to use a risky diet pill. Discussion Results suggest that links between IC and dieting risks may be moderated by women's BMI, and that these links hold when considering depressive symptoms. Future longitudinal research would benefit from a better understanding of the potential directional links between BMI, depression, and diet pill use.

Abstract
Fear of negative evaluation (FNE) is a transdiagnostic risk factor that has an important role in eating disorder (ED) onset and maintenance, as well as other psychopathologies. However, no research has explored whether FNE has associations with probable ED status when accounting for related vulnerabilities, and whether this relationship changes across gender and weight status. The current study sought out to explore how FNE explains probable ED status above and beyond heightened neuroticism and low self-esteem, with gender and BMI serving as potential moderators of this relationship. Participants were 910 university students (85 % females) aged 18-26 years (Mage = 19.90; SDage = 2.06) living in Australia, who completed measures of psychological distress, personality, self-esteem, FNE, and ED status. Logistic regression analysis showed that FNE was associated with probable ED status. This relationship was stronger among individuals with underweight and healthy-weight, whilst an interaction with gender was not significant. These findings shed light on the unique role FNE has in probable ED status across gender, which appears to be more pronounced in those with a lower BMI. Therefore, FNE should be considered as a potential target in ED screening and early intervention alongside other important transdiagnostic risk factors.

Abstract
It remains unexplained why some behaviours persist despite being non-hedonic and ostensibly aversive. This phenomenon is especially baffling when such behaviours are taken to excess in the form of psychopathology. Anorexia nervosa is one psychiatric disorder in which effortful behaviours that most people find unpleasant (suchas restrictive eating) are persistently performed. We propose thatthe social psychology theory of learned industriousness providesa novel mechanistic account for such phenomena. This theoryposits that high-effort behaviour can be conditioned to acquire secondary reinforcing properties through repeated pairing with reward. Accordingly, effort sensations become less aversive andmore appetitive, increasing willingness to engage in effortful behaviour. In this Perspective, we review pre-clinical behaviouraland biological data that support learned industriousness, contrast learned industriousness with other models of non-hedonic persistence (such as habit learning), highlight evidence that supports learned industriousness in individuals with anorexia nervosa and consider implications of the model, including translation to other psychiatric presentations.

Abstract
There is a wealth of research that has highlighted the relationship between personality and eating disorders. It has been suggested that understanding how subclinical disordered eating behaviours are uniquely associated with personality can help to improve the conceptualization of individuals with eating disorders. This study aimed to explore how the facets of the Five-Factor Model (FFM) predicted restrictive eating, binge eating, purging, chewing and spitting, excessive exercising and muscle building among males and females. An online survey assessing disordered eating behaviours, FFM and general psychopathology was completed by 394 females and 167 males aged between 16 and 30 years. Simultaneous equations path models were systematically generated for each disordered eating behaviour to identify how the FFM facets, body dissatisfaction and age predicted behaviour. The results indicated that each of the six disordered behaviours were predicted by a unique pattern of thinking, feeling and behaving. Considerable differences between males and females were found for each path model, suggesting differences between males and females in the personality traits that drive disordered eating behaviours. It was concluded that it is important to take personality into account when treating males and females who engage in disordered eating behaviours.

Abstract
Eating disorder (ED) pathology in men is not as well understood or studied as ED pathology in women. One potential reason for this is that most of the traditional assessments used for EDs were developed for and validated with exclusively female samples, meaning that symptoms in men are not as well represented or measured. There are consistent associations between perfectionism and ED symptoms in women, but less is known regarding how these relationships function in men. This study examined whether the relationship of perfectionism to ED symptoms varies by gender using the Eating Disorder Examination-Questionnaire (EDE-Q) and the Eating Pathology Symptom Inventory (EPSI). The EPSI has multiple dimensions that may better capture the presentation of ED symptoms in men. Participants were recruited from a large public university and through Amazon MechanicalTurk. Participants completed a survey battery that included the two eating measures and the self-oriented perfectionism scale from the Hewitt and Flett Multidimensional Perfectionism Scale. Data were analyzed using independent samples t-tests and structural equation modeling. There were significant positive associations between self-oriented perfectionism and all dimensions measured by the EDE-Q and the EPSI. The models were invariant across gender. Implications for further research were discussed.

Abstract
PURPOSE OF REVIEW A growing body of research suggests psychedelic-assisted therapy (PAT) may be safe and effective for a variety of mental health conditions. Among these, eating disorders have been a recent target of interest. This review provides an up-to-date summary of the potential mechanisms and use of PAT in people diagnosed with eating disorders, with a focus on anorexia nervosa. RECENT FINDINGS Classic psychedelics may have transdiagnostic efficacy through several mechanisms relevant to eating disorder pathology. Interest in, and efforts to increase access to PAT are both high. Early clinical trials are focused on establishing the safety and utility of this treatment in eating disorders, and efficacy remains unclear. High-quality published data to support the use of PAT for people with eating disorders remains lacking. Recent studies however suggest PAT has the potential to augment the efficacy of current interventions for these difficult-to-treat conditions.

Abstract
Anabolic-androgenic steroids (AAS) are primarily used to improve physical appearance and increase lean muscle mass. Due to their masculinizing properties, the majority of people using AAS are men; however, AAS use among females may increase with changing body ideals trending towards a more muscular appearance. AAS use among males have been associated with risk-taking behavior, and increased prevalence of personality disorders and psychopathology. As a result of low perceived prevalence and stigma among females who use AAS, the relationship between AAS use and psychopathology in this population is not well-known. AAS using women (n = 16) and weight-lifting controls (WLC) (n = 16) completed questionnaires regarding AAS use, health and training information. Psychopathology was evaluated using the Millon Clinical Multiaxial Inventory-III (MCMI-III). Group differences on demographic variables and scores on MCMI-III scales were evaluated with Mann-Whitney U tests. The clinical cut-off was then applied to all MCMI-III scales and groups were compared using Fisher's exact test. AAS consumers demonstrated significantly greater psychopathology than WLC on several scales. Externalizing personality disorder scales were elevated among those who use AAS relative to controls, such as borderline (p < 0.001), antisocial (p = 0.007) and sadistic (p = 0.002), and in addition depressive (p = 0.012), negativistic (p = 0.001) and masochistic (p = 0.029) personality disorders scales. Furthermore, all clinical syndromes were elevated among AAS consumers. AAS consumers thus demonstrated multi-pathology, and 56% (n = 9) of the group met the clinical criteria for six or more disorders. Females who use AAS experience in general increased levels of psychopathology compared to WLC. Clinicians should be aware of these traits and the challenges they present in providing care to this population.

Abstract
BACKGROUND There are presently a number of eating disorder treatment interventions that have a research-evidence base to support their effectiveness. However, rates of attrition and treatment outcomes demonstrate that there is no one-size fits all for the treatment of eating disorders. Narrative therapy is a promising, but under-researched, intervention for the treatment of eating disorders (EDs). The aim of this study was to conduct a narrative synthesis of the literature to explore the content and use of narrative therapy in the treatment of EDs. METHOD Data were extracted from 33 eligible included studies following systematic search of five data bases. Data included aims and objectives, sample characteristics, treatment details and components of narrative therapy, which informed the narrative synthesis. The study is reported according to the Preferred Reporting items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS Narrative therapy interventions for EDs consisted of several components including the narrative worldview; unpacking the problem story; finding, thickening the meaning and performance of stories hidden by the problem story; and safety considerations. A notable proportion of the extracted articles discussed components of unpacking problem stories, and finding and re-authoring openings (or unique outcomes) that were hidden by problematic stories. Relatively fewer papers discussed the processes by identity shifts were performed or lived out, including in the eating practices of those with a lived ED experience. Furthermore, few papers addressed how therapists established client safety within the narrative framework when working with EDs. CONCLUSION This narrative synthesis found that narrative practitioners utilise a variety of narrative therapy techniques in working with individuals with a lived ED experience. The current literature has emphasis on specific narrative therapy techniques used in ED treatments, with some aspects of the narrative worldview and safety considerations left undiscussed. Additional research is needed to explore how identity shifts in narrative therapy are performed and lead to measurable behavioural changes, and to consider how safety considerations can be established within the narrative worldview. There are a number of psychological therapies for eating disorders that have research evidence-base. These treatments, however, do not work for everyone as indicated by drop-out rates and eating disorders running a severe and enduring course for some people. Narrative therapy is a therapeutic intervention that has been reported as a promising intervention for people with an eating disorder. The focus of narrative therapy is to engage the person in finding identities hidden by problem-saturated identities and in the performance of these hidden identities. In this review, we have explored the use of narrative therapy for eating disorders to identify what aspects of this therapy are currently being used and which components are less referenced in the literature. Findings from this study support the need for further research into narrative therapy components in the treatment of eating disorders, particularly how hidden identities are performed and safety considerations are integrated into this therapeutic intervention.

Abstract
Research has suggested that schizotypy-a personality organisation representing latent vulnerability for schizophrenia-spectrum disorders-may be elevated in women with symptoms of disordered eating. However, studies have not fully considered associations between symptoms of disordered eating and multidimensional schizotypy. To overcome this limitation, we asked an online sample of 235 women from the United States to complete measures of symptoms of disordered eating (drive for thinness, body dissatisfaction, and bulimic symptoms) and multidimensional schizotypy. Correlational analyses indicated significant associations between drive for thinness and bulimic symptoms, respectively, and most schizotypal facets. Body dissatisfaction was significantly associated with only two schizotypal facets. Overall, the strength of correlations was weak-to-moderate. Regression results indicated that only the schizotypal feature of excessive social anxiety was significantly associated with all risk for disordered eating factors. These results are consistent with aetiological models of disordered eating that highlight socio-affective difficulties as risk factors for symptoms of disordered eating.

An exploratory study of associations between the ICD-11 personality disorder model and eating pathology. J Eat Disord 2022; 10:130.

Abstract
BACKGROUND Recently, the International Classification of Diseases 11th Revision (ICD-11) has introduced a paradigm shift in personality disorder conceptualization. The novel ICD-11 personality disorder model comprises a dimensional assessment of personality dysfunction and five maladaptive personality trait domains. Maladaptive personality plays a central role in eating pathology. Yet, relations between the ICD-11 personality disorder model and eating pathology are, to date, unclear. Thus, this study aimed to explore the bivariate, incremental, and interactive associations of the ICD-11 personality disorder model components with eating pathology domains. METHODS A predominantly female (85%) sample of 888 German-speaking community adults completed validated self-report measures of personality dysfunction, the ICD-11 personality trait domains, and five eating pathology domains (drive for thinness, bulimia, body dissatisfaction, orthorexia, binge eating). Bivariate and hierarchical regressions models were used to investigate bivariate, incremental, and interactive relations between the ICD-11 personality disorder model components and eating pathology. RESULTS Personality dysfunction and the ICD-11 personality trait domains showed statistically significant bivariate relations with eating pathology. Additionally, personality dysfunction and most ICD-11 personality trait domains displayed incremental links with eating pathology. Finally, the relations of the ICD-11 personality trait domains with eating pathology were largely independent of the severity of personality dysfunction. CONCLUSIONS This study indicated that all ICD-11 personality disorder model components are uniquely linked to eating pathology. Beyond maladaptive personality trait domains, the strong and incremental relations of personality dysfunction with eating pathology have potential implications for theory building. Further research using longitudinal designs is needed to evaluate causal links between the ICD-11 personality disorder model components and eating pathology.

Abstract
(1) Background: Perfectionism has been linked to eating disorders and might be a risk factor for the appearance of eating pathologies. The aims of this study are (a) to verify the relationship between perfectionism, emotional eating (EE), binge eating (BE), and body mass index (BMI); (b) to identify the variables that predict BE symptoms and BMI; (c) to study the role of perfectionism as a mediator between EE and BMI. (2) Methods: 312 adult participants answered a cross-sectional survey that included the Multidimensional Perfectionism Scale, the Emotional Eater Questionnaire (EEQ), the Binge Eating Scale (BES), and a sociodemographic questionnaire including BMI. (3) Results: The results suggest a direct correlation between EE, BE, and BMI, showing that EE is a powerful predictor of BE symptoms and BMI. Furthermore, two dimensions of perfectionism have a mediator role between EE and BMI, specifically doubts and actions and concern over mistakes: the presence of these two components of perfectionism reverses the relationship between EE and BMI. (4) Conclusions: These results have significant implications for the understanding of the two different (pathological) eating patterns: intake restriction and overeating and should be considered in intervention programs.

Abstract
A significant proportion of those with eating disorders (EDs) do not respond to first-line treatments. This systematic review was conducted to identify whether personality disorders (PDs)/traits predict or moderate ED treatment outcomes and whether these outcomes were differentially influenced by ED or PD diagnostic subtypes, or treatment approach. A comprehensive systematic literature search was conducted using the PRISMA guidelines. A total of seven randomised controlled trials (RCTs) plus four follow-up studies were reviewed investigating the impact of PD and PD traits on treatment outcomes for EDs. The majority indicated that PD had some impact on treatment outcomes. Outcome measures and time-point measurements varied across studies. Included studies suggested that bulimia nervosa treatment outcomes were not hindered by co-morbidity of borderline PD; however, psychiatric impairment remained high at post-treatment and follow-up. Cluster C PDs were found to negatively impact treatment outcomes for binge ED and attrition rates for anorexia nervosa. Included studies suggested that interventions that addressed aspects of personality pathology showed greater main effects for ED treatment outcomes. There is an urgent need for future RCTs on ED treatments to include routine measures of core personality features to allow their impacts to be more thoroughly examined and for psychotherapies to be tailored accordingly.

Abstract
OBJECTIVE Eating disorders and borderline personality disorder have high rates of comorbidity. However, the extent to which individual BPD symptoms are elevated in patients with EDs is largely unknown. Meta-analyses examined: (1) which of the nine BPD symptoms are especially elevated in individuals with versus without EDs, (2) whether particular ED subtypes have elevated levels of certain BPD symptoms, and (3) which BPD symptoms remain unstudied/understudied in relation to EDs. METHODS We performed nine separate meta-analyses (one for each BPD symptom) to compare levels of symptoms in patients with EDs versus healthy controls. A total of 122 studies (range = 4-34 studies across symptoms) were included. RESULTS Affective instability was the BPD symptom most elevated, while anger was the BPD symptom least elevated, in patients with EDs compared to controls. When comparing effect sizes across ED subtypes, anorexia nervosa binge-eating/purging subtype had the largest effect sizes for the greatest number of BPD symptoms, while effect sizes for AN restrictive subtype were not significantly larger than those of other EDs for any BPD symptom. The least studied BPD symptoms were identity disturbance and interpersonal difficulties. DISCUSSION These meta-analyses suggest that certain symptoms of BPD play a more prominent role in the comorbidity between BPD and EDs than others. Targeting affective instability when treating cases of comorbid ED and BPD may be especially likely to ameliorate the negative outcomes related to this comorbidity. Future research should further investigate identity disturbance and interpersonal difficulties in the context of EDs. PUBLIC SIGNIFICANCE Having an eating disorder and borderline personality disorder is a common comorbidity associated with a severe clinical presentation. BPD is characterized by nine distinct symptoms. This research examined levels of individual BPD symptoms in patients with versus without EDs. Findings can guide researchers and clinicians towards studying and treating symptoms that may be most relevant for BPD-ED comorbidity and in turn, improve outcomes for these patients.

Abstract
Objective: Individuals with anorexia nervosa (AN), restricting type demonstrate unique emotional responses to hedonically positive stimuli beyond eating disorder (ED)-related stimuli. The goal of this study was to evaluate differences in responses to five types of emotionally positive stimuli among acutely ill anorexia nervosa (IAN), restricting type patients, weight-recovered anorexia patients (WRAN), and healthy controls (HCs) using affect modulated startle response (AMSR) as an objective measure. Method: A total of 28 participants were recruited (n=28). Fourteen participants were recruited as IAN using the Diagnostic and Statistical Manual of Mental Disorders-V (DSM-V) criteria, seven were WRAN, and seven were HC females. All participants were female and aged between 8 and 18 years. The participants viewed images depicting negative, neutral, standardized, and non-eating disorder (ED)-related positive stimuli. Additionally, four categories of ED-related stimuli (high-calorie food, body image, success, and parent-child relationships) were presented to all participants during a standard AMSR paradigm. Results: No significant between-group differences were found for any of the four ED stimulus categories; all groups showed an inhibited startle response to the four ED-related categories. In contrast, IAN and WRAN showed reduced hedonic responses to standardized positive stimuli relative to HC-replicating previous results. Reduced hedonic response to the standardized (non-ED) positive stimuli was highly correlated with self-reported social anxiety, low self-esteem, body dissatisfaction, asceticism, interpersonal problems, and ineffectiveness. Conclusion: AN patients had a reduced hedonic response to some non-ED-related positive stimuli, which correlated with several anxiety-related traits. In contrast, their early automatic responses to high-calorie food, normal weight models, images of success, and positive parent-child relationships did not differ from HC, suggesting these stimuli are either being evaluated as highly interesting or hedonically positive.

Compulsive overworking and eating disorders (EDs) show considerable similarities in terms of risk factors (e.g., rigid perfectionism), clinical manifestation (e.g., excessive controlling behaviors), and consequences (e.g., physical exhaustion and depression). This study aimed to examine the hypotheses that compulsive study behaviors (conceptualized as study addiction) are related to EDs and that they have independent negative effects on well-being among young musicians, who constitute a highly vulnerable population for these types of problematic behaviors. The relatively high prevalence of study addiction and its pronounced negative relationship with psychosocial functioning make it a pending challenge for sustainable education. A total of 255 students from various music academies in Poland took part in the study. The Bergen Study Addiction Scale, assessing compulsive studying (conceptualized as addictive behavior), the Eating Attitude Test-26 (EAT-26), the Perceived Stress Scale, the Hospital Anxiety and Depression Scale, and the quality-of-life measure were used. A structural equation model was investigated. Study addiction was positively related to the general factor of EDs and the social pressure component. Both problematic behaviors showed negative and independent effects on the well-being of young musicians. EDs may be 8 to 16 times more prevalent among the students of music academies who are addicted to studying than among the general population. About 80% of those students showing all seven symptoms of study addiction exhibited at least mild depression, while more than half had clinically significant levels of depression. Almost 90% had clinically significant levels of anxiety. Without addressing co-occurring study addiction and eating disorders, including their commonalities and idiosyncrasies, their prevention and treatment cannot be effective and it will substantially affect the sustainability of education and work.

Abstract
Impaired cognitive flexibility has been suggested as a risk factor for the development of anorexia nervosa (AN). The current study aimed to 1) investigate cognitive flexibility in people at various levels of risk of AN; and 2) compare people with a history of AN to people at different levels of risk of AN in cognitive flexibility. The sample comprised of 262 community participants (79% female) and 36 participants with a lifetime diagnosis of AN (97.2% female) aged between 18 and 64 years old. Participants completed self-report (the Depression Anxiety Stress Scale short-form version, the Eating Disorders Examination-Questionnaire, the Neuroticism Scale, and the Cognitive Flexibility Inventory) and neurocognitive (the Trail Making Test and the Wisconsin Card Sorting Test) assessments online to evaluate eating disorder symptoms, depression, neuroticism, and cognitive flexibility. Using a cluster analysis, participants were allocated into low-, medium-, and high-risk of AN groups (n = 88, 128, 46, and 36 respectively). Although high-risk participants self-reported significantly poorer cognitive flexibility than the other risk groups, performance on the neurocognitive tasks was similar across groups. Further, participants with lifetime AN reported significantly poorer cognitive flexibility than the low-risk group. People at high-risk of AN may perceive themselves to have poorer cognitive flexibility compared to those at a lower risk of AN. These results have implications for early identification of people at high-risk of AN.

Abstract
Even though the internet is a common source of information and treatment for people with eating disorder (ED) experience, the motives for illness-related searches have rarely been investigated beyond the perceived negatives. This study explores how women with ED experience reflect upon the advantages and disadvantages of their ED-related internet use. We expand the framework of the Uses and Gratifications Theory (U&G) into the context of users with ED experience through 30 semi-structured interviews with women with ED experience, aged 16 to 28, who live in the Czech Republic. Thematic analysis revealed four themes related to the pros and cons of their internet usage: ED-related Information Content; Internet Features Important to Users; Body Image; and Social Interaction. The results challenge the binary view of ED-related internet use and question some presumptions of U&G Theory within the specific context of users with ED experience.

Abstract
The Hierarchical Taxonomy of Psychopathology (HiTOP) is a quantitative nosological system that addresses shortcomings of traditional mental disorder diagnoses, including arbitrary boundaries between psychopathology and normality, frequent disorder co-occurrence, substantial heterogeneity within disorders, and diagnostic unreliability over time and across clinicians. This paper reviews evidence on the validity and utility of the internalizing and somatoform spectra of HiTOP, which together provide support for an emotional dysfunction superspectrum. These spectra are composed of homogeneous symptom and maladaptive trait dimensions currently subsumed within multiple diagnostic classes, including depressive, anxiety, trauma-related, eating, bipolar, and somatic symptom disorders, as well as sexual dysfunction and aspects of personality disorders. Dimensions falling within the emotional dysfunction superspectrum are broadly linked to individual differences in negative affect/neuroticism. Extensive evidence establishes that dimensions falling within the superspectrum share genetic diatheses, environmental risk factors, cognitive and affective difficulties, neural substrates and biomarkers, childhood temperamental antecedents, and treatment response. The structure of these validators mirrors the quantitative structure of the superspectrum, with some correlates more specific to internalizing or somatoform conditions, and others common to both, thereby underlining the hierarchical structure of the domain. Compared to traditional diagnoses, the internalizing and somatoform spectra demonstrated substantially improved utility: greater reliability, larger explanatory and predictive power, and greater clinical applicability. Validated measures are currently available to implement the HiTOP system in practice, which can make diagnostic classification more useful, both in research and in the clinic.

Abstract
PURPOSE Childhood abuse is associated with an increased risk of developing eating disorders (EDs) as well as personality disorders (PDs). However, their interaction is still uncertain, particularly in adolescents. This study investigates the correlations between childhood emotional neglect (CEN), childhood emotional abuse (CEA), and obsessive-compulsive and borderline personality styles in female adolescent inpatients with eating disorders (EDs). METHODS One hundred and twenty-eight inpatients (ages 14-18) were assessed, 54 were diagnosed with restricting-type anorexia nervosa (AN-R) and 33 with a binge-purging ED [BP-ED; comprising patients with binge-purging type anorexia nervosa (AN-BP), n = 15, and bulimia nervosa (BN), n = 18]. Fifty healthy participants made up the control group (CG). CEN and CEA were assessed with the Childhood Trauma Questionnaire, while the Personality Style and Disorder Inventory was implemented to determine personality styles. RESULTS A MANOVA revealed a significant main effect of CEA on spontaneous-borderline personality style [F(8,119) = 17.1, p < 0.001, η2 = 0.126], as well as a main effect of ED group on spontaneous-borderline [F(2,119) = 3.1, p = 0.048, η2 = 0.050]. A significant interaction between ED group, CEA, and spontaneous-borderline was found [F(2,119) = 3.5, p = 0.034, η2 = 0.055] with BP-ED showing significantly higher scores in CEA (9.3 ± 4.0) and in spontaneous-borderline (14.2 ± 6.2). CONCLUSIONS Considering CEA and borderline personality style in adolescent inpatients with BN or AN-BP may help improve the understanding of the etiology and maintenance of BP-ED and provide more effective treatment targets.

Abstract
China was a major hotspot during the beginning of the COVID-19 pandemic. Several studies have reported changes in residents' eating behaviors and appetite during city wide lockdowns and home confinements. However, few have investigated how neuroticism interacts with the impact of COVID-19 to influence eating behaviors during city lockdowns. Thus, the current study aims to establish a pathway model to understand social media exposure, negative affect, neuroticism, and their interaction with eating behaviors during the COVID-19 lockdowns. We present data from 1,128 participants (Mage = 24.34 ± 10.48 years) who completed an online survey between February 17 and 27, 2020. The extent of respondents' social media exposure, negative affect, eating behaviors, and desire for high-calorie food during city lockdowns, as well as the personality trait of neuroticism, were measured. Results show that city lockdowns and home confinements had a negative impact on residents' eating behaviors and appetite. Forty-eight percent of respondents showed moderate to constant emotional overeating, and respondents' desire for high-calorie food significantly increased. Correlation analysis showed that emotional overeating is positively associated with social media exposure, neuroticism, and anxiety. Then, a moderated mediation model was established, showing that heavy social media exposure could lead to emotional overeating through anxiety, and the association between social media exposure and anxiety varies depending on the extent of neuroticism. The current study provides novel insight into how the interaction of a personality trait and the stressful situation of COVID-19 influence people's negative emotions and eating behaviors.

Abstract
BACKGROUND The relationship between anorexia nervosa (AN) and family disturbance has been a subject of debate since its first description. What began as a clear view of the pathologically disturbed family causing AN has become ever more complex over the decades. OBJECTIVE The aim of this review is to explore the literature to examine the changes and evolution of clinical opinion around family dysfunction and AN over the last 20 years. METHODS A narrative review of heterogeneous studies in peer-reviewed publications sourced from the major databases, including PubMed and ScienceDirect, to illuminate the topic of family distress and AN by highlighting the conflicting and complementary ways it has been studied. RESULTS This review has highlighted the complexity of the relationship between anorectic sufferers and their families. It has explored the literature about parental burden, emotions and cognitive mechanisms together with parental attitudes about weight and shape. It is clear that there is no consistent psycho-social pathology in families which has been shown to be causative. However, over the last twenty years, research has highlighted the distress and family dysfunction caused by having to look after an anoretic child with poor mentalisation skills, insecure attachment and emotion dysregulation. CONCLUSION The area has become clearer over the last 20 years; research suggests a bi-directional relationship between AN and family dysfunction, with difficult dynamics becoming entrenched within the family. This is best addressed, the consensus suggests, by specialist family therapy and carer skills interventions. Longitudinal research is needed to definitively answer the question with rigorous scientific certainty. EMB RATING Level V. LEVEL OF EVIDENCE Level I: Evidence obtained from: at least one properly designed randomized controlled trials; systematic reviews and meta-analyses; experimental studies. Level II: Evidence obtained from well-designed controlled trials without randomization. Level III: Evidence obtained from well-designed cohort or case-control analytic studies. Level IV: Evidence obtained from with multiple time series analysis such as case studies. Dramatic results in uncontrolled trials might also be regarded as this type of evidence. Level V: Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

The role of positive self-compassion, distress tolerance, and social problem-solving in the relationship between perfectionism and disordered eating among racially and ethnically diverse college students.

Abstract
Eating disorders (EDs) are associated with high levels of distress, functional impairment, and morbidity. Perfectionism has been consistently identified as an important factor in the etiology and maintenance of disordered eating, and as a promising target for treatment efforts. To address the detrimental effects of perfectionism on disordered eating, further research is needed to better understand what mechanisms may influence the relationship between these variables. In the present research, we examined three constructs related to self-regulation as potential mediators of the relationship between perfectionism and disordered eating: positive self-compassion, distress tolerance, and social problem-solving. We collected data from a sample of racially and ethnically diverse undergraduate students (N = 280) using an online questionnaire battery. Using structural equation modeling (SEM), we developed measurement and structural models to meet criteria for good fit and tested the hypothesized relationships. Distress tolerance emerged as a robust, statistically significant mediator of the relationship between perfectionism and disordered eating. Social problem-solving and self-compassion did not mediate this relationship. Distress tolerance may counterbalance the cognitive load associated with perfectionism; freeing up mental resources to focus on resisting urges for immediate relief through engagement in maladaptive disordered eating.

Abstract
Features of personality disorders (PDs) have been found to explain meaningful variance in the onset, maintenance, and symptomatic presentation of eating disorders (EDs), and a co-occurent personality pathology is commonly associated with poorer response to ED treatment. The "pathoplasty model" of the relationship between personality and EDs implies that, once both conditions are established, they are likely to interact in ways that modify therapy outcome; however, to date, no studies have explored overall personality functioning, and especially PD clusters, as a mediator of treatment outcome. The present study aimed at conjointly exploring the associations between personality functioning and PDs, respectively, with pre-treatment ED symptomatic impairment and therapy outcome; and the mediating role of personality variables. At treatment onset, a sample of 107 women with ED problems were evaluated using both the Structured Clinical Interview for DSM-5 (SCID-5-CV) and the Shedler-Westen Assessment Procedure-200 (SWAP-200)-a clinician-rated procedure to dimensionally assess personality. Participants were also asked to complete self-report questionnaires on overall ED symptomatology, symptoms of binge eating and purging behaviors, and therapy outcome. The findings showed that, over and above the categorical ED diagnosis, the SWAP-200 healthy personality functioning score mediated the relationship between baseline ED symptom severity and therapy outcome, as well as the association between baseline bulimic symptoms and treatment outcome; furthermore, SWAP-200 Cluster B PD scores mediated the link between baseline binge eating and purging symptoms and therapy outcome, whereas scores in Clusters A and C showed no significant effects. The findings suggest that personality-based outcome research may improve treatment effectiveness in this difficult-to-treat population.

Abstract
Purpose: The relationship between anxiety or depressive comorbidities, their chronology of onset, and the severity of anorexia nervosa (AN) is not well-studied. We hypothesize that the existence of a comorbidity, particularly before the onset of AN, is associated with greater severity of AN. Methods: One hundred seventy-seven subjects were assessed. The prevalence of major depressive disorder (MDD), obsessive-compulsive disorder (OCD), generalized anxiety disorder (GAD), and social phobia (SP) as well as their chronology of onset were studied. The assessment criteria of AN severity were the overall clinical condition, body mass index (BMI) on admission, lowest BMI, intensity of the eating symptoms, age at the onset of AN, illness duration, number of hospitalizations, and quality of life. Results: Patients with AN had the greatest clinical severity when they had a comorbid disorder over their lifetime, such as MDD, GAD, or SP. These comorbidities along with OCD were associated with a higher level of eating symptoms and a more altered quality of life. A profile of maximum severity was associated with a higher prevalence of MDD and GAD. Concerning the chronology of onset, the age at the start of AN was later in cases of MDD or GAD prior to AN. Conclusion: There seems to be an association between severity of AN and both MDD and GAD. The chronology of onset of the comorbidity did not seem to be associated with the severity.

Fumagalli G, Margola D. Is personality the key in cognitive-behavioural therapy for eating disorders? A review. Clin Psychol Psychother 2021; 29:164-177. [PMID: 34110647 DOI: 10.1002/cpp.2627] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Revised: 05/13/2021] [Accepted: 06/03/2021] [Indexed: 11/08/2022]
Abstract
The efficacy of individual cognitive-behavioural therapy (CBT) for eating disorders can be assessed by investigating the potential predictors, mediators and moderators of treatment. The present review focused on personality since its crucial role has been emphasized both by research and practice. Sixteen studies were collected, and data were extracted through a highly operationalized coding system. Overall, personality disorders were the most investigated construct; however, their influence was somewhat contradictory. A more cogent result occurred for borderline personality disorder (BPD) when considered as a moderator (not a predictor nor a mediator). Patients with a more disturbed borderline personality benefited to a greater extent from treatments including booster modules on affects, interpersonal relationships and mood intolerance, rather than symptoms exclusively. Nine additional personality dimensions, beyond BPD, were investigated sparsely, and results regarding them were barely indicative in this review. However, some of these dimensions (e.g., affective lability and stimulus-seeking behaviours) could be traced back to BPD, thereby strengthening evidence of the role of borderline disorder as a moderator. Although research on the relationship between personality and eating disorders needs to be increased and methodologically improved, personality, taken as a whole, emerged as a promising variable for enhancing the efficacy of CBT.

Turk F, Kellett S, Waller G. Determining the potential links of self-compassion with eating pathology and body image among women and men: A cross-sectional mediational study. Body Image 2021; 37:28-37. [PMID: 33548664 DOI: 10.1016/j.bodyim.2021.01.007] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2020] [Revised: 01/21/2021] [Accepted: 01/21/2021] [Indexed: 11/15/2022]
Abstract
This study examined whether rumination, shame, self-criticism, and perfectionism mediate the previously established link between self-compassion and both eating and body image concerns. A cross-sectional online survey was completed by a community sample of non-clinical adult women (n = 369) and men (n = 201). Participants completed standardised measures of self-compassion (predictor), rumination, external shame, perfectionism and self-criticism (mediating variables), and eating pathology and body image (criterion variables). Path analyses confirmed that higher self-compassion was serially linked to lower eating pathology and body dissatisfaction through comparative self-criticism and external shame. Compared with women, the association between higher self-compassion and lower body dissatisfaction was weaker in men. However, there were no mediating effects of rumination, perfectionism, or internalized self-criticism. Overall results indicate notable similarities between women and men, and emphasise the potential value of targeting external shame during eating disorder prevention and treatment. Longitudinal study of these constructs is warranted in future research.

Abstract
PURPOSE Although personality has been widely researched in patients with anorexia nervosa (AN) and bulimia nervosa (BN), the nature of this relationship has not yet been clearly articulated. The pathoplasty model theorizes that personality might shape symptomatic presentation and thus affect therapeutic outcomes, but more research is needed. The present study aimed at investigating the predictive value of a broad spectrum of personality traits in determining AN and BN treatment outcomes, considering both the statistical and clinical significance of the therapeutic change. METHODS Eighty-four female patients with AN and BN treated in a residential program were evaluated at treatment onset using the Shedler-Westen Assessment Procedure-200-a clinician-rated measure of personality disorders and healthy personality functioning. At both intake and discharge, patients completed the Eating Disorder Inventory-3 to assess eating symptoms and the Outcome Questionnaire-45.2 to evaluate overall impairment. RESULTS Considering overall ED symptomatic change, multiple regression analyses showed that, even when controlling for baseline symptoms and DSM-5 categories, schizoid (B = 0.41, p ≤ 0.01), avoidant (B = 0.31, p ≤ 0.05), and paranoid (B = 0.25, p ≤ 0.05) personality features predicted worse therapeutic outcomes. Similar results were found when applying the clinical significance approach, with the emotionally dysregulated factor as an additional negative predictor of significant/reliable change (B = - 0.09; p < 0.01). Healthy personality functioning predicted better therapeutic outcomes (B = - 0.34, p ≤ 0.001). CONCLUSIONS Pathoplastic models and personality-based research in this clinical population have the potential to inform effective treatment strategies by targeting relevant individual factors. LEVEL OF EVIDENCE Level III, longitudinal cohort study.

Abstract
BACKGROUND Personality has been suggested to be an important factor in understanding onset, maintenance, and recovery from eating disorders (ED). The objective of the current study was to evaluate personality style in different ED diagnostic groups as classified in the Diagnostic and Statistical Manual of Mental Disorders, Fifth edition (DSM-5). METHODS The overcontrolled, undercontrolled, and resilient personality styles were compared in four groups of patients with EDs: anorexia nervosa restricting (ANr) (n = 34), anorexia nervosa binge eating/purging (ANbp) (n = 31), atypical anorexia nervosa (AAN) (n = 29), and bulimia nervosa (BN) (n = 76). These groups were compared with a group of patients with borderline personality disorder (BPD) (n = 108), and a non-clinical group (NC) (n = 444). Patient data were collected at two outpatient clinics in Uppsala, Sweden. NC control data were collected through convenience sampling. Participants filled out questionnaires assessing personality style. RESULTS The main findings were more pronounced overcontrol reported by the ANr and AAN groups compared with the BN, BPD, and NC groups, and no significant difference in resilience between the ED and the NC groups. Considerable variability of over- and undercontrol was also found within each group. CONCLUSIONS The results replicate previous findings when EDs are classified according to current diagnostic criteria (DSM-5). Taking personality styles into account may improve our understanding of certain characteristics in EDs, such as social deficits and rigidity that are attributed to poor treatment outcome.

Abstract
Research supports an association between altered interoceptive accuracy, or the ability to accurately monitor sensations from the body, and disordered eating. However, the behavioral mechanism through which interoceptive accuracy may influence eating behaviors is unclear. Intuitive eating, the ability to regulate food intake according to visceral cues of hunger and satiety, is positively related to interoceptive accuracy and negatively related to disordered eating. Therefore, we hypothesized that interoceptive accuracy would be negatively associated with intuitive eating which would, in turn, influence eating disorder risk. A mediation analysis was performed to test this hypothesis in a sample of 41 undergraduate women who completed a heartbeat counting task to assess interoceptive accuracy, followed by self-report measures of intuitive eating ability and eating disorder risk. We found that eating for physical rather than emotional reasons and reliance on hunger and satiety cues, two aspects of intuitive eating, mediated the relationship between interoceptive accuracy and eating disorder risk. Although further research is necessary, it is possible that findings regarding the association between interoceptive accuracy and intuitive eating may inform the development of eating disorder prevention efforts.

Abstract
PURPOSE There is a significant relationship between childhood trauma and the development of an eating disorder in adolescence or adulthood, possibly influenced by circulating levels of inflammatory parameters. The main objective is to identify and describe a subgroup of patients with eating disorders and a history of trauma in childhood or adolescence with differential clinical features. METHODS An observational study on a sample of 55 patients who met the diagnostic criteria for any DSM-5 eating disorder was carried out. Inflammatory parameters in white blood cells were examined. Patients underwent different assessments, including clinical and personality scales. RESULTS Patients with a history of trauma had higher scores in the delirious and narcissistic items of the Millon Clinical Multiaxial Inventory (MCMI-II) (p < 0.05) and a higher score in the paranoid item of the SCID-5 Personality Disorders Version (SCID-5-PD) (p < 0.05). Patients with distinguishing personality features were grouped according to the Childhood Trauma Questionnaire sexual subscale. Tumor necrosis alpha (TNF-α) showed a significant association with childhood trauma history. CONCLUSIONS There is a profile of patients with eating disorders who have increased activity in the inflammatory pathways that, if identified precociously, can benefit from specifically aimed interventions.

Associations Between Trauma, Early Maladaptive Schemas, Personality Traits, and Clinical Severity in Eating Disorder Patients: A Clinical Presentation and Mediation Analysis. Front Psychol 2021; 12:661924. [PMID: 33868136 PMCID: PMC8044897 DOI: 10.3389/fpsyg.2021.661924] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2021] [Accepted: 03/11/2021] [Indexed: 12/12/2022] Open
Abstract
Background: The literature has shown a significant association between traumatic experiences and eating psychopathology, showing a greater symptomatology in patients with trauma history. Less is known about the associations between trauma and cognitive schemas, and personality traits and the differences between childhood and adulthood trauma experiences. Thus, this paper aims to assess the clinical and psychological characteristics of eating disorder (ED) patients, looking for differences between patients without a history of trauma and patients with trauma experiences, as well as at possible differences between exposure in childhood, adulthood, or repeated events. Another aim of the paper is to evaluate the possible mediation role of cognitive schemas and personality traits in the relationship between early trauma and eating psychopathology. Methods: From January to November 2020, 115 consecutive inpatients admitted for a specific multidisciplinary ED treatment in a dedicated Unit were evaluated for trauma, differentiating between trauma occurring in childhood and adulthood. The subjects were evaluated for early maladaptive schemas (EMS), personality traits, trauma symptomatology, quality of life, and specific psychopathologies linked to EDs. Mediation analyses between childhood and adulthood trauma and eating psychopathology were performed, with EMS and personality traits as mediators. Results: Patients with a history of trauma showed higher physical and psychological symptomatology scores, with a more impaired clinical profile in patients with both childhood and adulthood trauma exposure. The mediation analysis showed a specific mediator role for the “disconnection and rejection (DR)” EMS factor in the relationship between childhood trauma (cT) and eating psychopathology. Conclusion: Trauma experiences are associated with more severe clinical symptomatology in EDs and may need a specific assessment in patients with failed outpatient standard treatments. Specific cognitive schemas linked to DR domain should be evaluated in treatments for ED patients with history of trauma due to the mediation role between trauma and eating psychopathology. The need for outcome studies about treatment approaches for ED patients with history of trauma is discussed.

Abstract
Background: Binge eating disorder (BED) is clinically relevant by virtue of the global impairment, poor quality of life, and increased overall medical morbidity. The high comorbidity with psychiatric disorders, particularly depression, has received attention as a possible mediator of the poor outcome. Further, BED and depression share cognitive dysfunctions. This naturalistic and uncontrolled pilot study aimed at evaluating the efficacy of vortioxetine (VTX) on depressive symptoms in patients with BED, secondly the efficacy in improving a broad array of executive functions, and third to explore the effect on eating behavior and body weight. Methods: This pilot study involved 30 patients with BED and comorbid MDD, treated with VTX for 24 weeks. Assessments were run at baseline (t 0), 4 (t 1), 8 (t 2), 12 (t 3), and 24 (t 4) weeks. Changes in depressive symptoms (HDRS and BDI), executive functions, eating behaviors (binge frequency and severity, night eating, food addiction), and body weight were estimated after treatment with VTX through GLM. Results: Significant improvements emerged after treatment with VTX in: depression (HDRS p < 0.001; BDI p = 0.002) regardless the dose of VTX and first diagnosis (BED/MDD), working memory (RAVLT acquisition p = 0.01, delay recall p < 0.001, RCFT percentage of recall p = 0.01, and Attentional Matrices p = 0.05), binge days frequency (p < 0.001), binge eating severity (BES p < 0.001), night eating (p = 0.001), food addiction (YFAS 2.0 p = 0.039), and body weight (p = 0.039). The improvement in depressive symptoms was associated with the concurrent improvement in night eating as assessed by the I-NEQ. Conclusions: VTX can be a valid therapeutic choice for patients with BED with comorbid depression in controlling the depressive symptoms, working memory, and eating behavior. Indeed, by acting on affective symptoms, neurocognitive functioning, and eating behaviors, it confirms the results already obtained with VTX in other disorders, expanding them to BED.

Abstract
PURPOSE The many studies examining the relationship between anorexia nervosa (AN) and personality abnormalities have observed high comorbidity. However, no definitive studies to date have established whether there is a causal connection or whether it is a complication. The current study aimed to explore the nature of the relationship between personality disorder (PD) traits, obsessionality and perfectionism, using a study design that allows the testing of some comorbidity models. METHODS Twenty-nine women were recruited from a group of former AN patients treated during their adolescence in a specialized unit around 20 years before the time of this study. They were divided into two groups according to the current presence of eating disorder (ED) symptoms (current-ED, n = 11; recovered, n = 18). Both groups were compared to a matched control group (n = 29) regarding current PD traits, obsessive beliefs and perfectionism. RESULTS Borderline PD traits, most cluster C PD traits and overestimation of threat were more common in the current-ED group than in the control and recovered groups. Obsessive-compulsive PD traits, intolerance of uncertainty, and perfectionism were also significantly more prevalent in the current-ED group compared to controls but did not reach significance when compared to the recovered group. No significant differences were found between the recovered and control groups. CONCLUSION Our results mostly support the personality abnormalities observed as a transient effect related to the presence of ED psychopathology in patients with adolescent-onset AN. LEVEL OF EVIDENCE Level III, case-control analytic studies.

Abstract
OBJECTIVE Recent studies on atypical interoceptive capabilities have focused on clinical populations, including anorexia nervosa[1,2]. The present exploratory study aims to characterize the influence of disordered eating symptomology on interoceptive capabilities in college students, a population for which dangerous dieting behaviors may emerge. METHOD Ninety-nine participants were randomized to consume a blinded high calorie or low calorie midday shake. Participants reported frequency of eating disorder cognitions and behaviors; indicated changes in satiety, happiness, and energy pre- and post-consumption; and guessed the calories in their shake. Outcomes (perceived satiety, changes in mood, and caloric guess) were regressed on eating disorder symptoms scores, the high/low calorie shake condition, and the interaction between these predictors. RESULTS Those randomized to receive the high calorie shake reported feeling fuller, but only when endorsing lower levels of eating concern. Those randomized to the high calorie shake reported greater post-meal happiness, but only at greater levels of eating concerns. Lastly, those with lower levels of eating restraint reported an expected positive association between level of fullness and calorie guess, but those with higher levels of eating restraint did not exhibit any relationship between perceived fullness and calorie guess. DISCUSSION Results of this exploratory suggest that irregular eating habits (e.g., not eating a sufficient amount for lunch) may have direct consequences on interoceptive capabilities. Further, these capacities may be impacted by individual differences in eating concern and restraint. Preliminary findings suggest that impairment in deciphering visceral signals may be associated with the degree of eating disorder symptomology; such impairment may occur at lower levels of symptomatology than normative data would indicate.

Abstract
OBJECTIVE We examined how personality traits are associated with eating pathology (EP) across a range of severities and symptom subtypes. METHOD The National Comorbidity Survey Adolescent Supplement (N = 10,148) was used to compare personality across severities (i.e., clinical Eating Disorders [EDs], subclinical disordered eating, preclinical weight concerns, or no weight/EP [no W/EP]), subclinical subtypes (i.e., Binge Eating Only, Binge-Purge, Binge-Restrict, Restrict-Purge, or no W/EP), and clinical subtypes (i.e., Anorexia Nervosa [AN]), Bulimia Nervosa [BN], Binge Eating Disorder [BED], internalizing disorders, or no ED or internalizing disorder) of EP. RESULTS More severe EP was associated with more extreme personality trait endorsements. Impulsivity-related traits did not consistently distinguish binge eating/purging from restricting subtypes, although behavioral disinhibition differentiated adolescents with BN or BED from AN. CONCLUSION Personality traits related to affectivity and impulsivity were more consistently associated with severity rather than subtype of EP.

Neuropsychiatr Dis Treat 2021; 17:2053-2062.

Abstract
Studies using functional magnetic resonance imaging (fMRI) have contributed to our understanding of possible neural abnormalities among individuals with eating disorders. Many of these studies have focused on three domains: 1) cognitive control, 2) reward processing, and 3) affective processing. This review attempts to summarize the recent fMRI findings across these domains among the most well-characterized eating disorders: anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). Though the literature is a bit murky, a few major themes have emerged. Cognitive control systems are affected among individuals across eating disorder diagnoses, but effects seem least pronounced in AN. Specifically, individuals with all eating disorders appear to show decreased prefrontal activation during cognitive control, but there is less evidence in AN linking decreased prefrontal activation with behavior. There is some evidence that the reinforcing value of food is reduced in AN, but individuals with BN and BED show hyperactivation to rewarding food-related stimuli, suggesting the reinforcing value of food may be enhanced. However, more complex reward processing paradigms show that individuals with BN and BED exhibit hypoactivation to reward anticipation and provide mixed results with regards to reward receipt. There are fewer neuroimaging findings related to affective processing, yet behavioral findings suggest affective processing is important in understanding eating disorders. Though the extant literature is complicated, these studies represent a foundation from which to build and provide insight into potential neurobiological mechanisms that may contribute to the pathophysiology of eating disorders.

Evaluating empirically valid and clinically meaningful change in intensive residential treatment for severe eating disorders at discharge and at a 6-month follow-up. Eat Weight Disord 2020; 25:1609-1620. [PMID: 31673985 DOI: 10.1007/s40519-019-00798-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2019] [Accepted: 10/14/2019] [Indexed: 10/25/2022] Open
Abstract
PURPOSE The present study evaluated the statistical and clinical significance of symptomatic change at discharge and after 6 months of an intensive residential treatment for patients with eating disorders (ED), and explored the individual factors that may affect therapeutic outcomes. METHODS A sample of 118 female ED patients were assessed at intake and discharge on the following dimensions: BMI, ED-specific symptoms, depressive features, and overall symptomatic distress. A subsample of 59 patients filled out the same questionnaires at a 6-month follow-up after discharge. RESULTS Findings evidenced statistically significant changes in all outcome measures at both discharge and follow-up. Between 30.1 and 38.6% of patients at discharge and 35.2-54.2% at the 6-month follow-up showed clinically significant symptomatic change; additionally, 19.8-29.1% of patients at discharge and 22.9-38.3% at follow-up improved reliably. However, 34.9-39.8% remained unchanged and 2-4.8% worsened. At the 6-month follow-up, 21.3-25.9% showed no symptomatic change and 0-3.7% had deteriorated. Unchanged and deteriorated patients had an earlier age of ED onset and were more likely to suffer a comorbid personality pathology and to be following concurrent pharmacological treatment. CONCLUSIONS Results suggested that intensive and multimodal residential treatment may be effective for the majority of ED patients, and that therapeutic outcomes tend to improve over time. Prevention strategies should focus on early onset subjects and those with concurrent personality pathology. LEVEL OF EVIDENCE Level III, evidence obtained from a longitudinal cohort study.
