Eating Disorders in Men

BACKGROUND

Eating disorders are seen mainly as a problem affecting women, not just by the public at large, but also in specialized circles. Although it is true that more women than men suffer from all types of eating disorder, pertinent reviews have clearly shown that they do indeed occur in men, and that the available evidence on the matter is limited. The stigmatization of men with eating disorders makes it harder for these men, and for the relevant professionals, to recognize the symptoms and to seek or provide help.

METHODS

This review is based on publications retrieved by a selective search in PubMed on the epidemiological, diagnostic, clinical, and therapeutic aspects of eating disorders in men.

RESULTS

Current estimated lifetime prevalences in men are 0.2% for anorexia nervosa, 0.6% for bulimia nervosa, and 1% for bingeeating disorder; the corresponding figures for women are 1.4%, 1.9%, and 2.8%. Men and women may display different manifestations. Women are thought to be mainly seeking a slim figure and weight reduction; men, a muscular build. The established Germanlanguage screening and diagnostic tools, however, do not cover the types of symptoms that are more common in men. Little is known about whether treatment yields comparable results in men and women.

CONCLUSION

It is important to combat the stigmati - zation of men with eating disorders and to remove the obstacles to their appropriate diagnosis and treatment. The current methods of screening and diagnosis need to be adapted to take account of the special aspects of abnormal eating behavior in men. It remains unclear whether and how the disorderspecific treatment of these conditions in men should differ from their treatment in women.

[Gender Inequalities of the COVID-19 Pandemic: A Synthesis of Systematic Reviews with a Focus on Sexual and Gender Minorities]

OBJECTIVE

From the very beginning of the COVID-19 pandemic, gender was shown to play a significant role in how people were affected by it, while aspects related to sexual and gender minorities (SGM) have been rather understudied. The aim of this review was to synthesize systematic reviews and meta-analyses that explicitly addressed the impact of gender within the context of the pandemic, with a focus on SGM.

METHODS

We based the narrative synthesis of results on a literature search of PubMed. We included systematic reviews and meta-analyses as of 2019 with an identifiable gender comparison or SGM reference and a specified clinical outcome.

RESULTS

The search yielded 2 658 hits; 29 systematic reviews were included for content synthesis. Of these, we identified 23 systematic reviews with gender comparisons and 8 related to SGM. Men showed higher prevalence, severity, and mortality of COVID-19 compared with women, but the psychological consequences of the COVID-19 pandemic affected women more compared with men. Evidence suggests that women are at higher risk for Long-COVID-19. SGM experienced increased mental health problems during the COVID-19 pandemic compared to the general population.

DISCUSSION

It appears that biological and social risks led to differential susceptibility to infection and manifestation of COVID-19 disease and also accounted for differences in mortality between men and women. Insights on prevalence, disease burden, and mortality among SGM during the COVID-19 pandemic are lacking. This suggests an underrepresentation of SGM in COVID-19-related research. Despite the abundance of COVID-19 publications, gender effects have not often been explicitly and adequately studied.

CONCLUSION

Future studies should examine gender differences and needs and concerns of SGM in mental disorders and further understudied entities like Long-COVID-19, to gain insights and help to provide preventive measures and adequate treatments for all, for potential future pandemics as well.

How evaluative pairings improve body dissatisfaction in adult women: evidence from a randomized-controlled online study

BACKGROUND

Many young women are dissatisfied with their bodies. This study investigated the effect on current body dissatisfaction levels of a newly developed evaluative conditioning procedure that paired self-similar and self-dissimilar images of bodies with positive and neutral affective images, respectively. We hypothesized that learning the contingency that self-similar bodies predict positive affectivity is one process that could aid in explaining how these procedures function.

METHODS

Adult women without disordered eating pathology participated in an online experiment with random assignment to an intervention or a control condition. All participants initially rated body images in self-similarity and were subsequently asked to categorize positive and neutral images by valence as quickly and accurately as possible. In the intervention condition, self-similar bodies systematically preceded positive images, and self-dissimilar images preceded neutral images, creating a similar body → positive contingency. Pairings in the control condition were unsystematic such that no contingency was present. We measured categorization latencies and accuracies to infer contingency learning as well as current body dissatisfaction immediately before and after exposure to the pairings. All participants further completed measures of trait body image concerns and disordered eating psychopathology at baseline, which we examined as moderators of an expected relation between condition assignment, contingency learning, and body dissatisfaction improvements.

RESULTS

We analyzed data from N = 173 women fulfilling the inclusion criteria. Moderated mediation analyses showed that assignment to the intervention (vs. control) condition predicted increased similar body → positive contingency learning, which in turn predicted improved body dissatisfaction post-intervention, but only among women with higher pre-existing trait body image concerns or disordered eating levels.

CONCLUSIONS

The findings point toward the relevancy of further exploring the utility of pairing procedures. Similar body → positive contingency learning predicted improved body dissatisfaction in individuals with normatively high body image concerns, which suggests pairing procedures could help inform future research on reducing body dissatisfaction.

The State Urge to be Physically Active-Questionnaire (SUPA-Q): Development and validation of a state measure of activity urges in patients with eating disorders

OBJECTIVE

Many people, including patients with eating disorders (EDs), experience an increased urge for physical activity. "Trait"-like activity in patients with EDs is assessed by existing questionnaires, but there are few clinically validated assessments of a "state" urge to be physically active. Here, we developed and validated the State Urge to be Physically Active-Questionnaire (SUPA-Q).

METHODS

After developing and piloting the items, N = 126 patients with EDs (mostly anorexia nervosa and bulimia nervosa) took part in our mixed-longitudinal validation study with one primary assessment for all patients and a secondary assessment for a subsample of patients. Cronbach's α and split-half-methods served as measures of consistency and reliability. Correlations with other questionnaires were used to determine convergent and divergent validity, and confirmatory factor analysis was used for investigating factorial validity. We used paired-samples t-tests for repeated assessments to investigate change sensitivity.

RESULTS

We found the SUPA-Q to be highly consistent, and reliable and to demonstrate convergent, divergent, and factorial validity. The comparison of SUPA-Q scores from repeated assessments within a subsample of patients demonstrated the questionnaire's change sensitivity, Cohen's d = 0.48. Moreover, an increase in SUPA-Q scores was associated with a less positive mood, more anxiety, more body dissatisfaction, more tenseness, less feelings of control, and more stress.

DISCUSSION

The newly developed SUPA-Q may help to accentuate the necessity to evaluate and address the acute urge to engage in physical activity in patients with EDs in clinical practice and ultimately support tailoring treatments to patients' unique symptom patterns. The questionnaire is available at https://doi.org/10.17605/OSF.IO/G2YBC.

Sociodemographic and clinical features of men and women with eating disorders: a diagnosis-matched, retrospective comparison among inpatients

Introduction

Eating disorders (EDs) are among the most severe mental disorders in women and men, often associated with high symptom burden and significant limitations in daily functioning, frequent comorbidities, chronic course of illness, and even high mortality rates. At the same time, differences between men and women with EDs remain poorly explored.

Methods

In this study, we compared 104 men to 104 diagnosis-matched women with EDs regarding sociodemographic and clinical features. Using latent class mixture modelling, we identified four distinct patient subgroups based on their sociodemographic features.

Results

Men with EDs had significantly higher odds than women to belong to a "single-childfree-working" class. Moreover, while there were few overall differences in ED-related symptoms and general psychopathology between men and women, single-childfree-working men with EDs presented with higher general psychopathology symptoms than men in the other classes.

Discussion

We discuss how considering sex and gender along with further sociodemographic differences in EDs may help to improve ED diagnosis and treatment.

Exploratory graph analysis (EGA) of the dimensional structure of the eating disorder examination-questionnaire (EDE-Q) in women with eating disorders

This study examined the dimensional structure of the German Eating Disorder Examination-Questionnaire (EDE-Q) in clinical groups of women with Anorexia Nervosa (AN; N = 821), Bulimia Nervosa (BN; N = 573), and Binge-Eating Disorder (BED; N = 359) using Exploratory Graph Analyses (EGA). The EGA yielded a 12-item-four-dimension structure for the AN group (subscales "Restraint", "Body Dissatisfaction", "Preoccupation", "Importance"), a 20-item-five-dimension structure for the BN group (subscales "Restraint", "Body Dissatisfaction", "Eating Concern", "Preoccupation", "Importance"), and a 17-item-four-dimension structure for the BED group (subscales "Restraint", "Body Dissatisfaction", "Concern", "Importance"). This first investigation of the EDE-Q's dimensional structure using EGA suggests that the original factor model may be suboptimal for specific clinical ED samples and that alternative scoring should be considered when screening specific cohorts or evaluating the effects of interventions.

Factor structure of the Eating Disorder Examination-Questionnaire (EDE-Q) in adult men with eating disorders

BACKGROUND

Previous investigations on the Eating Disorder Examination-Questionnaire (EDE-Q) factor structures in men have been restricted to non-clinical settings, limiting conclusions about the factorial validity in men with eating disorders (ED). This study aimed to examine the factor structure of the German EDE-Q in a clinical group of adult men with diagnosed ED.

METHODS

ED symptoms were assessed using the validated German version of the EDE-Q. Exploratory factor analysis (EFA) using principal-axis factoring based on polychoric correlations was conducted for the full sample (N = 188) using Varimax-Rotation with Kaiser-Normalization.

RESULTS

Horn's parallel analysis suggested a five-factor solution with an explained variance of 68%. The EFA factors were labeled "Restraint" (items 1, 3-6), "Body Dissatisfaction" (items 25-28), "Weight Concern" (items 10-12, 20), "Preoccupation" (items 7 and 8), and "Importance" (items 22 and 23). Items 2, 9, 19, 21, and 24 were excluded due to low communalities.

CONCLUSIONS

Factors associated with body concerns and body dissatisfaction in adult men with ED are not fully represented in the EDE-Q. This could be due to differences in body ideals in men, e.g., the underestimation of the role of concerns about musculature. Consequently, it may be useful to apply the 17-item five-factor structure of the EDE-Q presented here to adult men with diagnosed ED.

Gender differences in individuals with obesity and binge eating disorder: A retrospective comparison of phenotypical features and treatment outcomes

OBJECTIVE

Phenotypical comparisons between individuals with obesity without binge eating disorder (OB) and individuals with obesity and comorbid binge eating disorder (OB + BED) are subject to ongoing investigations. At the same time, gender-related differences have rarely been explored, raising the question whether men and women with OB and OB + BED may require differently tailored treatments.

METHOD

We retrospectively compared pre- versus post-treatment data in a matched sample of n = 180 men and n = 180 women with OB or OB + BED who received inpatient treatment.

RESULTS

We found that men displayed higher weight loss than women independent of diagnostic group. In addition, men with OB + BED showed higher weight loss than men with OB after 7 weeks of treatment.

CONCLUSIONS

The present findings add to an emerging yet overall still sparse body of studies comparing phenotypical features and treatment outcomes in men and women with OB and OB + BED; implications for further research are discussed.

CLINICAL TRIAL REGISTRATION

The study was prospectively registered with the German Clinical Trial Register as part of application DRKS00028441.

Donor and Donation Images (DDI)-A Scoping Review of What We Know and What We Don't

Organ transplantation is associated with significant physical and psychological burden for the recipients. Qualitative reports indicate that organ recipients develop donor and donation images (DDI)-conceptions of the donor and/or the organ. A deeper understanding of DDI is needed in the care of transplant recipients. To present the current state of knowledge, we searched for and identified DDI-related publications in PubMed and Scopus. Inclusion criteria were (1) studies addressing transplant recipients, and (2) English or German language. Twenty-one studies of individuals with transplanted hearts, lungs, or kidneys were included in this scoping review. Prevalence for DDI ranged from 6% to 52.3%. DDI occurs both before and after transplantation and includes ideas about the donor as well as whether and how the recipient's personality may be altered by the transplanted organ. Some transplant recipients did indeed report personality changes following transplantation due to the adoption of assumed donor characteristics. One study showed a positive association between the presence of DDI and anxiety scores and one described a coping effect. DDI is understudied and should be systematically assessed to improve care for the vulnerable group of individuals undergoing organ transplantation. Current research gaps and future directions are discussed.

Medical Students' Perspectives on LGBTQI+ Healthcare and Education in Germany: Results of a Nationwide Online Survey

The healthcare needs of lesbian, gay, bisexual, trans*, queer, and intersex (LGBTQI+) persons are often overlooked, prompting national and international calls to include diversity-related competencies into medical students' training. However, LGBTQI+-focused healthcare education targets remain elusive, as surveys reveal considerable variability across national student populations. To generate empirical data and vocalize recommendations for medical education, we conducted the first nationwide online survey among 670 German medical students from 33 universities. Overall, most respondents reported low confidence regarding their medical training preparing them for LGBTQI+ patients, stated that LGBTQI+ themes were not covered during training, and agreed that the inclusion of such themes is urgently needed. In addition, we found gender and LGBTQI+ community member status to be key variables. Men scored lower in knowledge than women, while community members scored higher than non-community members. Similarly, community members reported higher comfort levels. Non-community men showed the highest levels of prejudice and efficacy beliefs, while at the same time had the lowest scores in contacts and the perceived importance of LGBTQI+-related teaching. Keeping subgroup differences in mind, we recommend that educational training should include LGBTQI+ healthcare aspects and address self-efficacy beliefs in future medical professionals to overcome LGBTQI+ healthcare disparities.

Gender Differences in Treatment Outcomes for Eating Disorders: A Case-Matched, Retrospective Pre–Post Comparison

Eating disorders (EDs) are increasingly emerging as a health risk in men, yet men remain underrepresented in ED research, including interventional trials. This underrepresentation of men may have facilitated the development of women-centered ED treatments that result in suboptimal outcomes for men. The present study retrospectively compared pre- vs. post-treatment outcomes between age-, diagnosis-, and length-of-treatment-matched samples of n = 200 men and n = 200 women with Anorexia Nervosa (AN), Bulimia Nervosa (BN), Binge Eating Disorder (BED), or Eating Disorder Not Otherwise Specified (EDNOS), treated in the same setting during the same period, and using the same measurements. Compared to women, men with AN showed marked improvements in weight gains during treatment as well as in ED-specific cognitions and general psychopathology. Likewise, men with BED showed marked weight loss during treatment compared to women with BED; ED-specific cognitions and general psychopathology outcomes were comparable in this case. For BN and EDNOS, weight, ED-specific cognitions, and general psychopathology outcomes remained largely comparable between men and women. Implications for treatments are discussed.

The impact of the COVID-19 pandemic on eating disorders: A systematic review

OBJECTIVE

A growing body of evidence suggests that individuals with eating disorders (EDs) have experienced deteriorating symptoms, increased isolation, and an increase in hospital admissions as a result of the COVID-19 pandemic. Despite this, no systematic reviews have been conducted examining the COVID-19 and ED peer-reviewed literature. Therefore, this systematic review aimed to synthesize the impact of the COVID-19 pandemic on individuals with EDs.

METHOD

Database searches of the peer-reviewed literature were completed in the subsequent databases: CINAHL, Embase, MEDLINE, and PsycINFO (from November 2019 to October 20, 2021). All research reporting on the relationship between the COVID-19 pandemic on individuals with EDs were included.

RESULTS

Fifty-three studies met the inclusion criteria, including 36,485 individuals with EDs. The pooled hospital admissions across the studies demonstrated on average a 48% (pre = 591, post = 876, n = 10 studies) increase in admissions during the pandemic compared to previous pre-pandemic timepoints. In this review, 36% of studies (n = 19) documented increases in eating disorder symptoms during the pandemic, this increase in eating disorder symptoms were documented in AN, BED, BN, and OFSED patients. Studies also demonstrated increases in anxiety (n = 9) and depression (n = 8), however patterns of change appeared to be diagnostic and timing specific (e.g., lockdowns).

DISCUSSION

We found a large increase in the number of hospitalizations and an increase in ED symptoms, anxiety, depression, and changes to BMI in ED patients during the pandemic. However, these changes appeared to be diagnostic and timing specific. Many qualitative studies described deterioration in ED symptomatology due to decreased access to care and treatment, changes to routine and loss of structure, negative influence of the media, and social isolation. Future studies are needed to focus on pediatric populations, new ED diagnoses, and severity of illness at presentation.

PUBLIC SIGNIFICANCE

The scientific literature suggests that individuals with eating disorders have experienced deteriorating symptoms, increased isolation, and an increase in hospital admissions as a result of the COVID-19 pandemic. This study synthesized 53 articles and explored the impact of the COVID-19 pandemic on patients with eating disorders. We found increases in eating disorder symptoms during the pandemic; this increase in eating disorder symptoms was documented in patients with common eating disorders including anorexia nervosa, binge-eating disorder, bulimia nervosa, and other specified feeding and eating disorders. This review also demonstrated changes in body mass index (an index used to classify underweight, overweight, and obesity in adults) and increases in anxiety and depression during the pandemic compared to previous timepoints; patterns of change appeared to be related to timing of lockdowns. This review provides important information on the impact of COVID-19 on the physical and mental health of individuals with eating disorders.

Gesundheitliche Themen von LSBTIQ+Personen in der ärztlichen Ausbildung in Deutschland

AIMS

Lesbian, gay, bisexual, trans, intersex and queer (LGBTIQ +) persons continue to experience discrimination and disadvantage in many areas of life, including healthcare. Studies indicate that LGBTIQ+persons show high rates of chronic physical and mental illness on the one hand, and report negative experiences with health care providers on the other hand. The aim of this work is to point towards barriers and the provision of inadequate health care for LGBTIQ+persons, and to draw attention to relevant gaps in medical education in Germany, needing to be followed by specific actions.

METHODS

For these purposes, both scientific evidence for the disadvantage of LGBTIQ+persons within the health care system and important innovative interventions in the education of medical personnel are presented and discussed.

RESULTS

A variety of different - in terms of scope, format, and content - training programs have already been tested and established, mainly in English-speaking regions of the world. In contrast, medical training in Germany lacks such programs.

CONCLUSIONS

Raising awareness and expanding the training of medical students to include LGBTIQ+health topics is of great importance in Germany.

A Plea for Diversity in Eating Disorders Research

Eating disorders (EDs) are often stereotyped as affecting the SWAG, that is, as affecting mostly skinny, White, affluent girls. Over the last decade, however, significant progress has been made toward increasing diversity in ED research. There is consensus that EDs affect individuals of all genders, ages, sexual orientations, ethnic, and socio-economic backgrounds, with recent studies exploring social determinants of ED etiology, ED presentation, and developing diversity-affirming ED assessments. This article provides a brief summary of current developments related to diversity as a research theme, and proposes different perspectives toward further improving diversity in ED research. Specifically, we argue for exploring the role of diversity in ED treatment settings and outcomes, for pursuing diversity-oriented research pro-actively rather than as a reaction to issues of under-representation, and for integrating diversity across different areas of medical education and trainings in psychotherapy. Limitations with respect to the paucity of research, and the link between diversity as a research theme and ED-related workforce diversity are discussed.

The prevalence of substance use disorders and substance use in anorexia nervosa: a systematic review and meta-analysis

AIM

Individuals with anorexia nervosa (AN) often present with substance use and substance use disorders (SUDs). However, the prevalence of substance use and SUDs in AN has not been studied in-depth, especially the differences in the prevalence of SUDs between AN types [e.g., AN-R (restrictive type) and AN-BP (binge-eating/purge type]. Therefore, this systematic review and meta-analysis aimed to assess the prevalence of SUDs and substance use in AN samples.

METHOD

Systematic database searches of the peer-reviewed literature were conducted in the following online databases: MEDLINE, PsycINFO, Embase, and CINAHL from inception to January 2021. We restricted review eligibility to peer-reviewed research studies reporting the prevalence for either SUDs or substance use in individuals with AN. Random-effects meta-analyses using Freeman-Tukey double arcsine transformations were performed on eligible studies to estimate pooled proportions and 95% confidence intervals (CIs).

RESULTS

Fifty-two studies met the inclusion criteria, including 14,695 individuals identified as having AN (mean age: 22.82 years). Random pooled estimates showed that substance use disorders had a 16% prevalence in those with AN (AN-BP = 18% vs. AN-R = 7%). Drug abuse/dependence disorders had a prevalence of 7% in AN (AN-BP = 9% vs. AN-R = 5%). In studies that looked at specific abuse/dependence disorders, there was a 10% prevalence of alcohol abuse/dependence in AN (AN-BP = 15% vs. AN-R = 3%) and a 6% prevalence of cannabis abuse/dependence (AN-BP = 4% vs. AN-R = 0%). In addition, in terms of substance use, there was a 37% prevalence for caffeine use, 29% prevalence for alcohol use, 25% for tobacco use, and 14% for cannabis use in individuals with AN.

CONCLUSION

This is the most comprehensive meta-analysis on the comorbid prevalence of SUDs and substance use in persons with AN, with an overall pooled prevalence of 16%. Comorbid SUDs, including drugs, alcohol, and cannabis, were all more common in AN-BP compared to AN-R throughout. Therefore, clinicians should be aware of the high prevalence of SUD comorbidity and substance use in individuals with AN. Finally, clinicians should consider screening for SUDs and integrating treatments that target SUDs in individuals with AN. Individuals with anorexia nervosa (AN) may also present with substance use or have a substance use disorder (SUDs). Thus, we conducted a systematic review and meta-analysis to determine the prevalence of substance use and substance use disorders in individuals with AN. We examined published studies that reported the prevalence of either substance use or SUDs in individuals with AN. We found that substance use disorders had a 16% prevalence and that drug abuse/dependence disorders had a prevalence of 7% in those with AN. These rates were much higher in individuals with binge-eating/purging type compared to the restrictive AN. However, many specific substance use disorders and substance use types were low in individuals with AN. Nonetheless, clinicians should be aware of the high prevalence of SUD comorbidity and substance use in individuals with AN.

One year in: The impact of the COVID-19 pandemic on help-seeking behaviors among youth experiencing eating disorders and their caregivers

We analyzed service utilization data from the National Eating Disorder Information Centre's (NEDIC) toll-free helpline/chat to assess the impact of the COVID-19 pandemic on help-seeking behaviors among youth with disordered eating and their caregivers. The number of contacts from affected youth (n = 650) and caregivers (n = 823) was significantly higher in the pandemic year than 2018 and 2019. The proportion of affected youth reporting dieting/restriction, perfectionism, and weight pre-occupation was significantly higher during the pandemic than in 2018 and 2019. Our findings lend support to accounts from expert clinicians reporting an increase in youth presenting with eating disordered symptoms during the pandemic.

Too hot to handle: Mood states moderate implicit approach vs. avoidance tendencies toward food cues in patients with obesity and active binge eating disorder

Patients with binge eating disorder (BED) display recurring episodes of eating large amounts of food in a short period of time, especially during negative mood states. However, the psychological processes linking negative mood to binge eating behavior have not been sufficiently explored. This study investigated the effects of experimentally inducing a negative (sad) mood state upon reaction times in a computerized Approach-Avoidance-Task (AAT) using images of foods and compared to a neutral control procedure in which negative mood was not induced. Differences in reaction times between "pulling" and "pushing away" food cues in the AAT were considered surrogates for fast, automatic (i.e., implicit) preferences ("bias") for either the approach or avoidance of foods. Obese patients with BED (n = 40), weight-matched (obese) individuals (n = 40), and norm-weight controls (n = 29) were asked to approach ("pull") or avoid ("push") images of high- and low-calorie foods following the induction of a negative mood state vs. the neutral control procedure. Sample size was within the common range of previous investigations of the kind. Similar to previous findings, obese patients with BED exhibited an avoidance bias (i.e., faster reaction times in "pushing" compared to "pulling") during the neutral control condition. However, a contrast analysis revealed that negative mood was associated with decreased avoidance bias in obese patients with BED, but not in obese and norm-weight controls. Mood status exerted no effect on BED patients' self-reported (i.e., explicit) ratings of the urge to consume foods. These findings may help to advance current understanding of how negative (sad) mood states may affect binge eating behaviors. Implications of these findings for developing novel treatment approaches are discussed.

Two of a Kind? Mapping the Psychopathological Space between Obesity with and without Binge Eating Disorder

(1) Background: Obesity (OB) is a frequent co-morbidity in Binge Eating Disorder (BED), suggesting that both conditions share phenotypical features along a spectrum of eating-related behaviors. However, the evidence is inconsistent. This study aimed to comprehensively compare OB-BED patients against OB individuals without BED and healthy, normal-weight controls in general psychopathological features, eating-related phenotypes, and early life experiences. (2) Methods: OB-BED patients (n = 37), OB individuals (n = 50), and controls (n = 44) completed a battery of standardized questionnaires. Responses were analyzed using univariate comparisons and dimensionality reduction techniques (linear discriminant analysis, LDA). (3) Results: OB-BED patients showed the highest scores across assessments (e.g., depression, emotional and stress eating, food cravings, food addiction). OB-BED patients did not differ from OB individuals in terms of childhood traumatization or attachment styles. The LDA revealed a two-dimensional solution that distinguished controls from OB and OB-BED in terms of increasing problematic eating behaviors and attitudes, depression, and childhood adversities, as well as OB-BED from OB groups in terms of emotional eating tendencies and self-regulation impairments. (4) Conclusions: Findings support the idea of a shared spectrum of eating-related disorders but also highlight important distinctions relevant to identifying and treating BED in obese patients.

All I Need Is Two: The Clinical Potential of Adding Evaluative Pairing Procedures to Cognitive Behavioral Therapy for Changing Self-, Body- and Food-Related Evaluations

Pairing procedures are among the most frequently used paradigms for modifying evaluations of target stimuli related to oneself, an object, or a specific situation due to their repeated pairing with evaluative sources, such as positive or negative images or words. Because altered patterns of evaluations can be linked to the emergence and maintenance of disordered cognitions and behaviors, it has been suggested that pairing procedures may provide a simple yet effective means of complementing more complex intervention approaches, such as cognitive behavioral therapy (CBT). Here, we summarize recent studies that explored the clinical potential of pairing procedures for improving self-esteem, body satisfaction, and food and consumption preferences. While no study has yet combined pairing procedures with CBT, there are several successful examples of pairing procedures in clinically relevant domains and clinical populations. We discuss potential sources of heterogeneity among findings, provide methodological recommendations, and conclude that pairing procedures may bear clinical potential as an add-on to classical psychotherapy.

Implicit bias to food and body cues in eating disorders: a systematic review

BACKGROUND

Rigid, restrictive eating patterns, fear of gaining weight, body image concerns, but also binge eating episodes with loss of control leading to overweight, at times followed by compensatory measures to control weight, are typical symptoms in eating disorders (EDs). The regulation of food intake in EDs may underlie explicit processes that require cognitive insight and conscious control or be steered by implicit mechanisms that are mostly automatic, rapid, and associated with affective-rather than cognitive-processing. While introspection is not capable of assessing implicit responses, so-called indirect experimental tasks can assess implicit responses underlying a specific behavior by-passing the participant's consciousness. Here, we aimed to present the current evidence regarding studies on implicit biases to food and body cues in patients with EDs.

METHODS

We performed a systematic review (PRISMA guidelines). We included controlled studies performed in clinical ED cohorts (vs. healthy control subjects or another control condition, e.g., restrictive vs. binge/purge AN) and using at least one indirect assessment method of interest.

RESULTS

Out of 115 screened publications, we identified 29 studies fulfilling the eligibility criteria, and present a synthesis of the essential findings and future directions.

CONCLUSION

In this emerging field of research, the present work provides cornerstones of evidence highlighting aspects of implicit regulation in eating disorders. Applying both direct (e.g., self-reports) and indirect measures for the assessment of both explicit and implicit responses is necessary for a comprehensive investigation of the interplay between these different regulatory mechanisms and eating behavior. Targeted training of implicit reactions is already in use and represents a useful future tool as an add-on to standard psychotherapeutic treatments in the battle against eating disorders.

Men's experiences of eating disorder treatment: A qualitative systematic review of men-only studies

WHAT IS KNOWN ON THE SUBJECT?: There is a widespread perception that eating disorders are predominantly women´s illnesses. Most studies in the field of eating disorders include predominantly women. Current eating disorder programmes are tailored to meet women´s needs. At the same time, studies show that the rate of eating disorders among men is rising. Men tend to seek help for their eating disorder late in the course of their illness; even when they do seek treatment, they run risk of being undiagnosed by health professionals. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: We assessed the current knowledge on how men think and feel about their eating disorders and explored how this may affect their help-seeking behaviours and how they go about managing their eating disorders. Men experience unique symptoms and issues that may translate into unique treatment needs. There is a call to re-evaluate the current status quo for men with eating disorders regarding access to and receiving treatment for their eating disorders. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: It is becoming an increasing priority to effectively treat men with eating disorders. Men need to be recognized as stakeholders in eating disorder-associated health care delivery. Healthcare professionals should receive training about the nature of eating disorders in men. Eating disorder-specific treatments will require adaptations to mirror the needs of individuals rather than particular gender/sex entities. ABSTRACT: Objective Despite the widespread perception that eating disorders (EDs) are predominantly experienced by women and girls, the incidence rate among men has risen substantially in recent years. Men may face unique challenges accessing treatment, which can negatively affect prognosis. The present paper aimed to review men's thoughts and feelings about their ED, and their experiences of ED treatment. Method We conducted a systematic search for qualitative articles focusing on the treatment experiences of men with EDs. Results Nine studies met inclusion criteria. Key themes that emerged across the studies were as follows: (a) recognition of the ED, (b) help-seeking, (c) treatment characteristics and (d) patient characteristics. Given that EDs are widely regarded to exclusively affect women and girls, men were reluctant to recognize their EDs, faced minimization of their symptoms by health professionals and had difficulty finding treatments that were tailored to their unique needs and preferences as men. Conclusions The present findings may serve as reference points to design future ED-specific interventions that are more inclusive of men. Further studies are needed to explore the differential experiences of men across diagnostic categories and treatment types, as well as elucidate the potential role of men-only services.

Exposure to the thin beauty ideal: Are there subliminal priming effects?

OBJECTIVE

Previous research suggested that exposure to the thin beauty ideal propagated by the media is associated with body dissatisfaction and the development of disordered eating. Given recent suggestions regarding the role of automatic processes, we aimed to enhance our understanding of automatic, unconscious responses to body pictures and the association with the internalization of the thin ideal and the severity of eating disorder symptoms.

METHOD

An affective priming task with body pictures of different weight as primes and a normal-weight body picture as target, which had to be evaluated with regard to attractiveness and desirability, was administered to healthy women with either subliminal prime presentation (Experiment 1) or conscious presentation (Experiment 2).

RESULTS

Subliminal presentation did not affect the evaluation of the normal-weight target, although strength of evaluative shifts was significantly associated with internalization of the thin ideal. In contrast, the conscious presentation of the ultra-thin prime decreased and of the obese prime increased desirability and attractiveness ratings of the target.

DISCUSSION

Prevention strategies focusing on the critical evaluation of the thin ideal are important. Future studies are warranted to enhance our understanding of automatic, unconscious processes in women experiencing eating disorders.

The impact of duration of illness on treatment nonresponse and drop-out: Exploring the relevance of enduring eating disorder concept

OBJECTIVE

There are no generally accepted definitions or markers of treatment nonresponse in eating disorders (EDs). The aim of this paper was to examine how the duration of illness and other potential prognostic markers impacted on nonresponse and drop-out from treatment across different EDs subtypes.

METHODS

A total sample of 1199 consecutively treated patients with EDs, according to Diagnostic and Statistical Manual of Mental Disorders, fifth edition criteria, participated in this study. Kaplan-Meier curves were calculated for each ED diagnosis in which the probability of recovery was plotted against the duration of illness.

RESULTS

Full remission was more likely for people with binge eating disorder (BED; 47.4%) and anorexia nervosa (AN; 43.9%) compared to bulimia nervosa (BN; 25.2%) and other specified feeding and EDs (OSFED; 23.2%). The cut-off points for the duration of the illness related with high likelihoods of poor response was 6-8 years among OSFED, 12-14 years among AN and BN and 20-21 years among BED. Other variables predicting nonresponse included dysfunctional personality traits.

CONCLUSIONS

Nonresponse to treatment is associated with duration of illness which is in turn associated with poor response to previous treatment. However, there was no evidence for staging the illness using specific duration of illness criteria. Nevertheless, the shorter temporal trajectory for OSFED suggests that early interventions may be of importance for this group.

The Prevalence of Impulse Control Disorders and Behavioral Addictions in Eating Disorders: A Systematic Review and Meta-Analysis

Aim: Individuals with eating disorders (EDs) may present with impulse control disorders (ICDs) and behavioral addictions (BAs), which may result in additional suffering and treatment resistance. However, the prevalence of ICDs and BAs in EDs has not been systematically examined. Therefore, this systematic review and meta-analysis aimed to assess the prevalence of ICDs and BAs in ED samples. Methods: A comprehensive electronic database search of the peer-reviewed literature was conducted in the following online databases: MEDLINE, PsycINFO, Embase, and CINAHL from their inception to May 2021. We restricted review eligibility to research studies reporting prevalence for ICDs or BAs in individuals with diagnosed EDs. The outcome for this review was the prevalence of ICDs or BAs in individuals with EDs. A series of random-effects meta-analyses were performed on eligible studies to estimate the pooled proportions and 95% confidence intervals (CIs). Results: Thirty-five studies met the inclusion criteria, including a total of 9,646 individuals identified as having an ED, 18 of these studies specifically examined ICDs/BAs in AN, BN, and BED. Random-effects pooled estimates demonstrated that the comorbid prevalence of any ICD was 22%. The prevalence of comorbid pathological/compulsive buying was highest (19%), followed by kleptomania (18%), pathological internet use (12%), intermittent explosive disorder (4%), trichotillomania (3%), and gambling disorder (2%). In addition, the prevalence of stealing/shoplifting behaviors was 30% in those with EDs. Conclusion: This is the first meta-analysis on the comorbid prevalence of EDs and ICDs/BAs. We found a moderate prevalence for these comorbid conditions, with approximately one out of five individuals with an ED also displaying a comorbid ICD/BA. Although causal inferences cannot be drawn, the numbers strongly suggest that clinical screening/monitoring of ICDs/BAs should be part of the clinical routine in cohorts with EDs. ED settings need either the capacity to manage these disorders or adequate access to relevant services. Further investigations are needed to reveal common underlying pathomechanisms.

A call to action to address COVID-19-induced global food insecurity to prevent hunger, malnutrition, and eating pathology

The coronavirus 2019 disease (COVID-19) pandemic has led to food shortages, increased food prices, and loss of income. As a result, global food insecurity alerts have been issued. The pandemic threatens millions of children and adolescents and their families currently living with or at risk for development of food insecurity. The lack of consistent access to nutritious food sources is associated with chronic physical and mental health problems and death. Studies on food insecurity and eating pathology have heightened our concern about the impact the added effect of the pandemic may have on eating behaviors of children and adolescents. Here, we want to draw attention to the need for making food security and healthy eating attitudes and behaviors a global priority during the COVID-19 pandemic to guarantee the current and future health and well-being of our children and adolescents.

Retrospective analysis of hypophosphatemia rates and other clinical parameters in patients with eating disorders

OBJECTIVE

To retrospectively assess medical services of a specialist inpatient eating disorders (EDs) unit.

METHOD

We retrospectively evaluated clinical parameters of 288 inpatients classified as 'moderately' or 'significantly' medically compromised between 1 January 2016 and 30 June 2019.

RESULTS

We analysed 288 patients (mean age 32.5 [SD = 11.4] years, 96% women, 76% with anorexia nervosa). Average length of stay was 38.4 (SD = 28.4) days. Average admission body mass index (BMI) was 14.8 (SD = 1.8) kg/m² , and 16.1 (SD = 1.9) kg/m² at 4 weeks. At admission, 82% of patients were considered significantly medically compromised, while 6% were deemed moderately compromised. Only 5% of patients required transfer to intensive care unit. Prevalence of hypophosphatemia was 17.7%; rates did not increase significantly between years despite more assertive re-feeding processes. There was no association between risk classification at admission and change in BMI at 4 weeks (F_(2,166) = 0.588, p = 0.557). BMI at admission was found to be significantly associated with clinical outcome (β = 0.92, p < 0.001).

DISCUSSION

Hypophosphatemia rates did not increase despite more assertive re-feeding over 3 years. Our results provide support for a model of treatment that simultaneously addresses the medical and psychiatric sequelae of patients with severe EDs.

The impact of the COVID-19 pandemic on help-seeking behaviors in individuals suffering from eating disorders and their caregivers

OBJECTIVE

To describe the impact of the COVID-19 pandemic on help-seeking behaviors among individuals with eating disorders and caregivers.

METHODS

We analyzed service utilization data from the National Eating Disorder Information Centre (NEDIC). We compared the number of contacts and symptom frequency between the pandemic period and previous years.

RESULTS

NEDIC was contacted 609 times during March 1-April 30, 2020 (72.1% individuals affected by disordered eating, 20.4% caregivers). The number of total contacts significantly increased from 2018 to 2019 and 2018 to 2020 (X²(3) = 50.34, p < .001). Among affected individuals (80.4% women), the number of contacts during the pandemic period was significantly higher (n = 439; X²(2) = 92.74, p < .001) compared to 2018 (n = 197) and 2019 (n = 312). There were higher rates of eating disorder symptoms, anxiety, and depression in 2020 compared to previous years. Thematic analysis of instant chats from the pandemic year revealed four emerging themes: 1) lack of access to treatment, 2) worsening of symptoms, 3) feeling out of control, and 4) need for support.

CONCLUSION

These findings point toward the impact of COVID-19 in individuals affected by disordered eating and hold implications for service delivery during times of crises.

Associations between pornography exposure, body image and sexual body image: A systematic review

There is evidence for associations between pornography exposure and sexual behaviors of adults and adolescents. Here, we review associations between pornography exposure and body image/sexual body image. Using a systematic search, we found 26 studies meeting inclusion criteria. Compelling evidence shows that frequency of pornography exposure is associated with negatively perceived body image and sexual body image; both heterosexual men and women appear to be affected. Due to scarcity of studies in adolescents and non-heterosexual samples, findings cannot be generalized to adolescents or individuals who identify as sexual minorities. Implications and future directions are discussed.

Prevalence and psychopathology of vegetarians and vegans - Results from a representative survey in Germany

The aim of the study was to investigate the prevalence of, and attitudes toward, vegetarianism and veganism. We also assessed the association between vegetarianism/veganism and eating disorder, depressive, and somatic symptoms. A cross-sectional questionnaire survey in adults in Germany that was representative in terms of age, gender, and educational level was carried out. Data from 2449 adults (53.5% females) were included. Mean age was 49.6 (SD 17.1) years. A total of 5.4% of participants reported following a vegetarian or vegan diet. While the majority of participants agreed that vegetarian diets are healthy and harmless (56.1%), only 34.8% believed this to be true of vegan diets. The majority of participants also believed that a vegetarian (58.7%) or vegan (74.7%) diet can lead to nutritional deficiency. Female gender, younger age, higher education, lower body mass index (BMI), and higher depressive and eating disorder symptoms were found to be associated with vegetarianism/veganism. We did not find increased physical complaints in the group of vegetarians/vegans. Our results point toward a moderate prevalence of vegetarianism/veganism among the general population. Our findings suggest that health care professionals should keep eating disorder pathology, affective status in mind when dealing with individuals who choose a vegetarian/vegan dietary pattern.

Factor Analyses and Validity of the Transplant Evaluation Rating Scale (TERS) in a Large Sample of Lung Transplant Candidates

OBJECTIVE

It is well known that the occurrence of mental disorders is more common in lung transplant candidates compared to the general population. After transplantation mental disorders may negatively affect quality of life, adherence to immunosuppressive medication, as well as overall survival. Therefore, the identification of patients at risk is of utmost importance and in Germany pre-transplant psychosocial evaluation of the patients is required. To ensure high quality and comparability of these assessments, the use of psychometrically sound instruments is recommended. We applied the Transplant Evaluation Rating Scale (TERS), a broadly used expert interview. Two research groups have detected a two-factor structure of the TERS in different transplant samples; however, with slightly different results. The present study investigated which of the models would fit best in our sample of lung transplant patients. Additionally, we assessed convergent and predictive validity of the best fitting model to evaluate its clinical usefulness.

METHODS

Between 2016 and 2019, 390 lung transplant candidates were evaluated and included in the study. The median age was 53 years and 54% were male. TERS interviews were conducted by trained medical doctors and psychologists. The participants completed questionnaires assessing quality of life and levels of depression and anxiety. Transplant- and disease-specific variables (lung disease, listing date, oxygen use) were taken from the patient charts. Confirmatory factor analysis was used to test the two proposed TERS-models in the present sample.

RESULTS

The two-factor structure of the TERS reported by Hoodin and Kalbfleisch fit our sample best, showing good psychometric properties. The factor "emotional sensitivity" was highly correlated with quality of life and measures of psychosocial health while the factor "defiance" correlated with obstructive lung disease and older age but not with quality of life. The two factors showed differential predictive validity with regard to time until listing and pulmonary-specific quality of life 1 year after transplantation.

CONCLUSIONS

The two factors showed good psychometric properties, and differential convergent and predictive validity. However, further studies concentrating on the predictive value of the TERS and its factors regarding somatic outcomes (mortality, graft functioning) are required.

Review of Randomized Controlled Trials Using e-Health Interventions for Patients With Eating Disorders

BACKGROUND

In a world of technological advancements, electronic devices and services seem to be a promising way to increase patients' engagement in treatment and to help manage their symptoms. Here, we identified and analyzed the current evidence of RCTs to evaluate the effectiveness and acceptability of e-health interventions in the eating disorder (ED) field.

METHODS

We screened an initial cluster of 581 papers. In the end, 12 RCTs in clinical ED cohorts were included.

RESULTS

Some studies were conceived as stand-alone interventions, while others were presented as add-ons to ED-specific treatments. Studies varied in the type of EDs under investigation and in the e-health intervention applied (with vs. without therapist support vs. blended interventions; smartphone- vs. web-based). Only four studies reported explicit acceptability measures. Out of those, two reported high acceptability, one reported low acceptability, and one reported no significant difference in acceptability between groups. Four studies reported higher effectiveness of the e-health intervention compared to the control condition, e.g., reduction in maladaptive eating behaviors. Regarding control groups, three used a wait list design and nine had another kind of intervention (e.g., face-to-face CBT, or treatment as usual) as control.

DISCUSSION

So far, the evidence for acceptability and effectiveness of e-health interventions in EDs is very limited. There is also a lack of studies in older patients, adolescents, men, sexual and ethnic minorities. Shame/stigma is discussed in the context of e-health interventions for EDs. It remains unclear how severity of EDs affects the effectiveness of e-health interventions, how patients can channel the knowledge they acquire from e-health interventions into their actual behaviors, and how such interventions can better fit the needs of the individual patient to increase acceptability and effectiveness.

Review of Mindfulness-Related Interventions to Modify Eating Behaviors in Adolescents

There are few well-established treatments for adolescent eating disorders, and for those that do exist, remission rates are reported to be between 30 and 40%. There is a need for the development and implementation of novel treatment approaches. Mindfulness approaches have shown improvements in eating disorder-related psychopathology in adults and have been suggested for adolescents. The present review identifies and summarizes studies that have used mindfulness approaches to modify eating behaviors and to treat eating disorders in adolescents. Focused searches were conducted in Embase, Medline, and PsycINFO, and identified articles were checked for relevance. A small number of studies (n = 15) were designated as appropriate for inclusion in the review. These studies were divided into those that focused on the promotion of healthy eating/the prevention of disordered eating (n = 5), those that concentrated on targeted prevention among high risk adolescents (n = 5), and those that focused on clinical eating disordered adolescents (n = 5). Thirteen of the 15 studies reviewed reported at least one positive association between mindfulness treatment techniques and reduced weight/shape concerns, dietary restraint, decreased body mass index (BMI), eating in the absence of hunger (EAH), binge eating, increased willingness to eat novel healthy foods, and reduced eating disorder psychopathology. In summary, incorporating mindfulness to modify eating behaviors in adolescent non-clinical and clinical samples is still in the early stages, with a lack of data showing clear evidence of acceptability and efficacy. Further studies and preferably controlled conditions are warranted.

Associations between neuropsychological performance and appetite-regulating hormones in anorexia nervosa and healthy controls: Ghrelin's putative role as a mediator of decision-making

Anorexia nervosa (AN) is a severe eating disorder accompanied by alterations in endocrinological circuits and deficits in neuropsychological performance. In this study, a series of appetite-regulating hormones (ghrelin, leptin, cholecystokinin, PYY, adiponectin, and visfatin) were measured under fasting conditions in female patients with AN and female healthy controls. All of the participants also underwent a battery of neuropsychological assessment [namely the Iowa Gambling Task (IGT), the Wisconsin Card Sorting Test (WCST), and the Stroop Color and Word Test (SCWT)]. As the main finding, we found that higher ghrelin levels predict better performance in the IGT. Ghrelin may be a putative mediator of decision-making, a finding that has not been described so far. The role of ghrelin in decision-making can only be described as speculative, as there are hardly any additional evidence-based data published up to date. Further studies are warranted.

Protective factors of depressive symptoms in adult cancer patients: The role of sense of coherence and posttraumatic growth in different time spans since diagnosis

Purpose: The purpose of this study was to investigate the impact of posttraumatic growth (PTG) and sense of coherence (SOC) as protective factors on depressive symptoms at different time spans after cancer diagnosis. Design: In a cross-sectional study, adult cancer patients were recruited from the tumor clinics of the University Hospital in Erlangen (Germany) and from peer-support groups for cancer survivors. Sample: Participants included 157 adult patients with primary cancer or in remission (53.5% female; mean age: 58.0 ± 14.1 years; mean time since diagnosis: 46.7 ± 72.8 months) with various forms of cancer. Methods: Multiple linear regression analyses were conducted. The patients were divided into two groups (≤1 year and >1 year since diagnosis) to test the impact of PTG and SOC on depressive symptoms at different time intervals after diagnosis. The Posttraumatic Growth Inventory (PTGI), Sense of Coherence Scale (SOC-13), and Hospital Anxiety and Depression Scale (HADS) were applied. Findings: After controlling for major demographic and clinical variables, SOC (β = -.489, p < .001) was found to be the only significant predictor for depressive symptoms ≤ 1 year after diagnosis; >1 year after diagnosis, SOC (β = -.571, p < .001), PTG (β = -.318, p = .002), and metastatic cancer (β = .231, p = .023) were significant predictors of depressive symptoms (high levels of SOC as well as PTG, and having no metastatic cancer were associated with low manifestations of depressive symptoms). Conclusions: These findings suggest that SOC may be a protective factor against depressive symptoms in both the short as well as in the long term after cancer diagnosis, but PTG only in the long term. Implications for psychosocial providers or policy: To prevent the development of depressive symptoms in cancer patients, individuals with a low SOC should be detected and should receive psychological assistance.

The association of leptin secretion with cognitive performance in patients with eating disorders

This study is an investigation of neuropsychological performance in patients with anorexia nervosa, bulimia nervosa, and binge eating disorder and hormonal secretion patterns for ghrelin, leptin, insulin, and glucose. An oral glucose tolerance test (OGTT) was performed in a cohort of n = 30 female patients suffering from eating disorders as well as n = 20 control females. All participants underwent the Wisconsin Card Sorting Test (WCST), the Trail Making Test (TMT), and a go/no-go task using food vs. neutral stimuli. Patients with anorexia nervosa differed from controls in their leptin response to the OGTT. While the four groups under investigation did not differ in neuropsychological performance, we found leptin responses to the OGTT to be associated with performance in the food-specific go/no-go task. These preliminary results may indicate a putative association between leptin concentrations and neuropsychological performance, particularly in measures of inhibitory control. Further studies investigating the role of leptin in impulsive behaviors in eating disorders would be useful.

Assessment of Use and Preferences Regarding Internet-Based Health Care Delivery: Cross-Sectional Questionnaire Study

Background

There has been an incremental increase in the use of technology in health care delivery. Feasibility, acceptability, and efficacy of interventions based on internet technologies are supported by a growing body of evidence.

Objective

The aim of this study was to investigate use and preferences in the general adult population in Germany for remote, internet-based interaction (eg, email, videoconferencing, electronic medical records, apps).

Methods

A nationwide cross-sectional questionnaire survey in adults that was representative in terms of age, sex and educational level was carried out.

Results

A total of 22.16% (538/2428) of survey participants reported not using the internet for work or private use. The nonuser phenotype can be described as being older, having lower educational and income status, and living in less populated areas. The majority of participants within the cohort of internet users reported that they would not consider using electronic medical records (973/1849, 52.62%), apps (988/1854, 53.29%), or emails to report symptoms (1040/1838, 56.58%); teleconference with one (1185/1852, 63.98%) or more experts (1239/1853, 66.86%); or participate in video psychotherapy (1476/1853, 79.65%) for the purpose of medical consultation or treatment. Older age and lower educational level were the most robust predictors of assumed future denial of use.

Conclusions

Our results point toward low use and preference rates among the general population for the use of telemedicine. It also seems that those who might benefit from telemedical interventions the most, are, in fact, those who are most hesitating. These low use and preference rates of eHealth should be considered prior to designing and providing future telemedical care, supporting the need for easy-to-use, data secure solutions.

[Implicit Self-Regulation of Food-Intake: Consequences for Psychotherapy]

Explicit processes of self-regulation require insight and control during implementation and are therefore often experienced as being strenuous, while implicit processes of steering behavior are automatic, rapid and effortless. However, self-regulation is not always either explicit or implicit; all variants ranging from those that are entirely automatic to those being entirely under control are present. As individuals are not aware of their underlying implicit modes of self-regulation, it is necessary to create an approach that is proximal to affective processing, by-passing the cognitive, verbal level. Promising approaches of this kind are such including embodied experiences or such shifting the body to a state, in which the apperception of implicit mechanisms is facilitated. Given that therapeutic work of self-regulation is in many cases carried out on an explicit level of processing, the need for novel, neurobiologically founded strategies intervening on the implicit (pre-verbal) level are called for. Correspondent paradigms, e. g. the approach-avoidance task (AAT) for the assessment of implicit processes are presented here with regard to food-intake regulation. This work is a narrative (qualitative) review aiming at illustrating the field of implicit bias research as well as the development of new implicit bias training paradigms to be used as add-on in future psychotherapeutic treatments. Therefore, a selection of relevant studies based on subjective criteria was made. Thus, this work is not a systematic review and does not claim to be an exhaustive description of studies of this kind.

Gender-Related Patterns of Emotion Regulation among Patients with Eating Disorders

Difficulties in emotion regulation (ER) are common in females with eating disorders (ED). However, no study to date has analyzed ER in males with ED. In the study at hand, we assessed ER in males with ED and compared results to both females with ED and healthy controls (HC). We also examined associations between ER difficulties, personality, and psychopathology. A total of 62 males with ED were compared with 656 females with ED, as well as 78 male and 286 female HC. ER was assessed by means of the Difficulties in Emotion Regulation Scale (DERS). We found that males and females with ED showed greater ER difficulties compared to HC. Pronounced general psychopathology was a shared factor associated with higher ER difficulties in both males and females with ED. However, whereas higher novelty seeking, higher cooperativeness, lower reward dependence, and lower self-directedness were related to higher ER difficulties in females with ED, lower persistence was associated with ER difficulties in males with ED. In sum, males and females with ED show similar ER difficulties, yet they are distinct in how ER deficits relate to specific personality traits. Research on strategies promoting ER in the treatment of males with ED is warranted.

Mood and restrained eating moderate food-associated response inhibition in obese individuals with binge eating disorder

Recent research suggests that obese individuals with binge eating disorder (BED) show deficits in response inhibition, but findings are not consistent, especially when food-associated stimuli are presented. The aim of the present study was to assess the role of moderating factors by taking into account restrained eating and mood. Seventeen obese women with BED, 20 obese women without BED and 20 normal-weight controls (NW) were recruited. A go/no-go task with food-associated and control stimuli and questionnaires were administered. Obese BED showed less impairment of response inhibition to food-associated than to control stimuli, while this pattern was reversed in NW; no differences were observed for obese participants. Interestingly, group differences were moderated by the interaction of restrained eating and mood, and obese BED made the most commission errors to food-associated stimuli when they were restrained eaters and in a very positive mood at the time of testing. Our results might explain why some studies did not observe deficits in response inhibition to food-associated cues in BED.

Prospective, randomized, double-blind, placebo-controlled phase IIa clinical trial on the effects of an estrogen-progestin combination as add-on to inpatient psychotherapy in adult female patients suffering from anorexia nervosa

BACKGROUND

There is a need for novel treatment approaches in anorexia nervosa (AN). While there is broad knowledge with regard to altered appetite regulation and neuropsychological deficits in AN patients on the one hand, and the effects of estrogen replacement upon neuropsychological performance in healthy subjects on the other, up to now, no study has implemented estrogen replacement in AN patients, in order to examine its effects upon AN-associated and general psychopathology, neuropsychological performance and concentrations of peptide components of the hypothalamus-pituitary-adrenal (HPA) axis and within appetite-regulating circuits.

METHODS

This is a randomized placebo-controlled clinical trial on the effects of a 10-week oral estrogen replacement (combination of ethinyl estradiol 0.03 mg and dienogest 2 mg) in adult female AN patients. The primary target is the assessment of the impact of sex hormone replacement upon neuropsychological performance by means of a neuropsychological test battery consisting of a test for verbal intelligence, the Trail making test A and B, a Go/No-go paradigm with food cues and the Wisconsin Card Sorting Test. Secondary targets include a) the examination of safety and tolerability (as mirrored by the number of adverse events), b) assessments of the impact upon eating disorder-specific psychopathology by means of the Eating Disorder Examination Questionnaire (EDE-Q) and the Eating Disorder Inventory-2 (EDI-2), c) the influence upon anxiety using the State-Trait-Anxiety Inventory (STAI), d) assessments of plasma cortisol levels during a dexamethasone-suppression test and appetite-regulating plasma peptides (ghrelin, leptin, insulin, glucose) during an oral glucose tolerance test and, e) a possible impact upon the prescription of antidepressants.

DISCUSSION

This is the first study of its kind. There are no evidence-based psychopharmacological options for the treatment of AN. Thus, the results of this clinical trial may have a relevant impact on future treatment regimens. Novel approaches are necessary to improve rates of AN symptom remission and increase the rapidity of treatment response. Identifying the underlying biological (e.g. neuroendocrinological) factors that maintain AN or may predict patient treatment response represent critical future research directions. Continued efforts to incorporate novel pharmacological aspects into treatments will increase access to evidence-based care and help reduce the burden of AN.

The effect of dronabinol in a male patient with anorexia nervosa suffering from severe acute urge to be physically active

OBJECTIVE

A 27-year-old male suffering from chronic anorexia nervosa was admitted for inpatient psychotherapy suffering from severe urge to be physically active.

METHODS

An off-label treatment with dronabinol was initiated, to reduce his symptoms related to that urge. Several attempts to reduce symptoms including intensive psychotherapy and several psychopharmacological agents had failed in the past.

RESULTS

Following treatment with 7.5 mg dronabinol twice a day, the patient reported a significant reduction in his acute urge to be physically active. Also eating disorder-specific cognitions and compulsive behaviors remitted.

DISCUSSION

Previous studies have applied much lower doses and showed no effect of dronabinol upon the urge to be physically active. Up to date, the patient reported no side effects, especially no psychotropic effects. Implications of this case report are discussed.

Posttraumatic Stress Disorder, Quality of Life, and the Subjective Experience in Liver Transplant Recipients

Objective:

A high prevalence of posttraumatic stress disorder (PTSD) symptoms among transplant recipients has been associated with a low adherence to treatment and poor survival. It is crucial to detect and prevent the development of posttraumatic stress in transplant settings.

Methods:

We examined the prevalence of posttraumatic stress symptoms in 3 liver transplant recipients by means of the Essen Trauma Inventory (ETI), a self-report questionnaire. The Short Form-36 was used to assess the perceived health-related quality of life. Patients were asked to indicate the most traumatic events within the context of the liver transplantation procedure.

Results:

Five patients (4.9%) fulfilled the criteria for PTSD related to liver disease or transplantation (ETI score greater than 27). In these patients, diagnosis was confirmed by a structured clinical interview. Fourteen (13.6%) patients had a partial PTSD with the ETI score less than 27 and greater than 16. Posttraumatic stress symptoms were significantly associated with perceived poor physical and mental health-related quality of life. Patients reported that the physicians’ disclosure of diagnosis was experienced as traumatic, followed by treatment in an intensive care unit and the liver transplantation itself.

Conclusions:

The ETI resulted in prevalence rates for PTSD comparable to previous studies in liver transplantation settings. Medical professionals requested additional training in how to deliver severe diagnoses to patients.

Up to a Third of Renal Transplant Recipients Have Deficiencies in Cognitive Functioning

INTRODUCTION

Kidney transplantation is beneficial in improving cognitive abilities in patients with chronic kidney disease; however, there is still uncertainty concerning which cognitive domains benefit and to what extent.

AIM

In the present study, cognitive functioning of renal transplant recipients was compared to normative data. Sociodemographic and clinical parameters that were associated with low cognitive performance were identified.

DESIGN

A total of 109 renal transplant recipients (63% men) participated in the study, with a mean age of 51.8 (standard deviation [SD] = 14.2) years. The cognitive test battery consisted of measurements assessing memory, attention, executive function, reproductive, and deductive ability.

RESULTS

In all tests, participants showed mean scores ranging within 1 SD of the population means. However, except for tests measuring memory, the percentage of participants scoring more than 1 SD below normed means was higher than expected in a normal distribution of performance. In certain tests, up to a third of the participants scored below average. Participants with continuous low performance (11%) showed higher age, poorer education, a longer time since transplantation, higher serum levels of urea and creatinine, and were more likely to have a deceased donor allograft.

DISCUSSION

Altough cognitive performance in renal transplant recipients matches normative data and confirms former findings, the amount of patients scoring more than 1 SD below average suggests that there are a considerable number of patients whose cognitive performance in certain domains lies below those of the general population. The identified sociodemographic and biochemical factors might be helpful to identify renal transplant recipients at risk.

Virtual reality jogging as a novel exposure paradigm for the acute urge to be physically active in patients with eating disorders: Implications for treatment

The acute urge to be physically active is a relevant clinical phenomenon in patients suffering from eating disorders. In this study with n = 20 female patients with anorexia nervosa and n = 10 female patients with bulimia nervosa, a virtual reality (VR) jogging paradigm was applied as a novel highly immersive 3D exposure paradigm. Patients were asked to rate their acute urge to be physically active during the exposure procedure. A 10-item self-report questionnaire (smQ) was developed to capture the cognitive, emotional, and behavioral aspects of the acute urge to move. We hypothesized that exposure would lead to habituation of the urge to be physically active. We also hypothesized that leptin levels would be associated with the degree of the subjective urge to be physically active, while habituation would be associated with a decrease in stress hormones (α-amylase, cortisol, and cortisone in saliva). A statistically significant change in subjective scores in the smQ from baseline to postexposure was seen. Our novel VR paradigm may serve as a therapeutic tool for exposure and habituation of the urge of acutely engaging in physical activity in patients with eating disorders.

Integration of Clinical Examination, Self-Report, and Hair Ethyl Glucuronide Analysis for Evaluation of Patients With Alcoholic Liver Disease Prior to Liver Transplantation

Context:

A large proportion of liver transplants (LTXs) are performed due to alcoholic liver disease (ALD) in the final stage of organ insufficiency. In order to list patients for LTX, transplant centers commonly require 6 months abstinence from alcohol. However, significant differences have been reported between alcohol intake as indicated by self-report and biochemical markers of alcohol.

Objective:

In the present study, the usefulness of ethyl glucuronide analysis in hair (hETG) was examined during the evaluation procedure before listing patients with ALD for an LTX.

Design:

Cross-sectional survey.

Setting:

Psychosomatic evaluation.

Patients:

Seventy patients with ALD prior to listing for an LTX.

Interventions:

According to clinical assessment before listing patients with ALD (n = 233) for an LTX, hETG analysis was only performed in the patients who were assumed to deny or underreport their alcohol consumption (n = 70).

Main Outcome Measures:

The analysis of hETG by liquid chromatography–mass spectrometry, clinical interview.

Results:

By hETG analyses, 27 (38.6%) of the 70 patients tested positive for ongoing alcohol consumption.

Conclusions:

Selective use of hETG based on the clinical interview rather than widespread screening is a possible way to detect excessive alcohol consumption in patients with ALD in the transplant setting. The primary evaluation of a patient’s situation in its entirety should remain the superordinate standard procedure. An interdisciplinary approach to transplant candidates with an ALD is asked for.

[Media Exposure and Posttraumatic Stress Disorder: Review and Implications for Psychotherapy]

The posttraumatic stress disorder (PTSD) is conceptualised as a psychological reaction upon traumatic events of distinct threat. Especially after the terrorists´ attacks of September 11th 2001, the scientific evaluation of the impact of media coverage of war and terrorism on mental functions of healthy individuals and the question whether the exposure of previously traumatised individuals to media coverage of war and disasters may act as a trigger for a trauma re-activation has begun in the US. There are positive associations between media exposure and the presence of PTSD symptoms. The amount (length) of media consumption appears to be a crucial variable to consider. Psychotherapists are asked to broach the issue of a careful and self-protecting handling of media coverage during therapy.
