Parental verbal communication and modeling behavior during mealtimes shape offspring eating behavior - A systematic review with a focus on clinical implications for eating disorders.

OBJECTIVE: The aim of this review is to provide an overview of parental communication patterns during mealtimes, with a special emphasis being placed on the differences between families with and without a history of eating disorders. METHODS: The systematic review was conducted according to the PRISMA statement. A systematic literature search was carried out in PubMed, PubPsych and PsycINFO and the results were assessed for eligibility by two independent raters using the PICOS criteria. Only studies that included a mealtime observation were considered suitable for analysis of both explicit and implicit parental communication. RESULTS: The results of the review suggest that mothers communicate more, with more complexity, and with a greater variety of words with their children during mealtimes compared to fathers. The intention and type of communication is diverse and heterogeneous. In general, parents often tried to encourage their children to eat. Verbal modeling and co-eating appeared to be common behaviors. Mothers with a history of eating disorders expressed more negative emotions during eating than mothers without eating disorders. Findings regarding the use of positive comments and controlling speech are contradicting. DISCUSSION: The review outlines major fields of parent-child communication and modeling behavior around family meals which might be relevant to investigate and integrate into models of intergenerational transmission of eating behavior and disordered eating.

Mother-infant feeding interactions in mothers with and without eating disorder history: Results of a structured observational study.

BACKGROUND: A growing body of evidence suggests that children of mothers with eating disorders (EDs) have a greater risk of early feeding problems. Recognizing and reacting adequately to the infant's signals during feeding is crucial for the child's development of internal and external regulatory mechanisms of food intake. Parental EDs might affect this ability. Therefore, we investigated the quality of mother-infant interactions during feeding using video recording and a structured coding system. METHODS: The data of this pilot study was collected in a prospective cohort study investigating the influence of maternal EDs on child outcomes. Twenty women with ED history and 31 control women were videotaped while feeding their infant during a main meal at ten months postpartum. The mother-infant interactions were evaluated by two raters using the Chatoor Feeding Scale. We assessed birth outcomes, the mother's ED and depression status, breastfeeding practices, infant feeding problems and infant temperament by maternal self-report. RESULTS: Mothers with and without ED history scored very similar on the Feeding Scale, however mothers from the control group experienced more struggle for control with their infants during feeding (p = 0.046) and made more negative comments about the infant's food intake (p = 0.010). Mothers with ED history were more concerned about infant feeding at three months postpartum and reported significantly more problems with solid foods in their children. Birth outcomes were comparable between groups, except for lower weight-for-length birth percentiles in children of women with ED history. CONCLUSION: Whilst examined mothers with ED history are more concerned about feeding their children, ED psychopathology does not affect the quality of mother-infant interaction during feeding at the transition to autonomous eating at ten months of age.

Inhibitory Control Training Enhanced by Transcranial Direct Current Stimulation to Reduce Binge Eating Episodes: Findings from the Randomized Phase II ACCElect Trial.

INTRODUCTION: Binge eating disorder (BED) is characterized by recurrent binge eating (BE) episodes with loss of control. Inhibitory control impairments, including alterations in dorsolateral prefrontal cortex (dlPFC) functioning, have been described for BED. A targeted modulation of inhibitory control circuits by the combination of inhibitory control training and transcranial brain stimulation could be promising. OBJECTIVE: The aim of the study was to demonstrate feasibility and clinical effects of a transcranial direct current stimulation (tDCS)-enhanced inhibitory control training to reduce BE episodes and to generate an empirical basis for a confirmatory trial. METHODS: We performed a monocentric clinical phase II double-blind randomized trial with two parallel arms. Forty-one adult outpatients with full-syndrome BED according to DSM-5 received six sessions of food-related inhibitory control training, randomly combined with 2 mA verum or sham tDCS of the right dlPFC. The main outcome was BE frequency within a 4-week interval after treatment termination (T8; primary) and at 12-week follow-up (T9; secondary) as compared to baseline. RESULTS: BE frequency was reduced in the sham group from 15.5 to 5.9 (T8) and to 6.8 (T9); in the verum group, the reduction was 18.6 to 4.4 (T8) resp. 3.8 (T9). Poisson regression with the study arm as the factor and baseline BE frequency as the covariate revealed a p value of 0.34 for T8 and 0.026 for T9. Sham and real tDCS differed at T9 in BE frequency. CONCLUSIONS: Inhibitory control training enhanced by tDCS is safe in patients with BED and results in a substantial and sustainable reduction in BE frequency which unfolds over several weeks post-treatment. These results constitute the empirical basis for a confirmatory trial.

Virtual Reality Exposure to a Healthy Weight Body Is a Promising Adjunct Treatment for Anorexia Nervosa.

INTRODUCTION/OBJECTIVE: Treatment results of anorexia nervosa (AN) are modest, with fear of weight gain being a strong predictor of treatment outcome and relapse. Here, we present a virtual reality (VR) setup for exposure to healthy weight and evaluate its potential as an adjunct treatment for AN. METHODS: In two studies, we investigate VR experience and clinical effects of VR exposure to higher weight in 20 women with high weight concern or shape concern and in 20 women with AN. RESULTS: In study 1, 90% of participants (18/20) reported symptoms of high arousal but verbalized low to medium levels of fear. Study 2 demonstrated that VR exposure to healthy weight induced high arousal in patients with AN and yielded a trend that four sessions of exposure improved fear of weight gain. Explorative analyses revealed three clusters of individual reactions to exposure, which need further exploration. CONCLUSIONS: VR exposure is a well-accepted and powerful tool for evoking fear of weight gain in patients with AN. We observed a statistical trend that repeated virtual exposure to healthy weight improved fear of weight gain with large effect sizes. Further studies are needed to determine the mechanisms and differential effects.

The humoral immune response more than one year after SARS-CoV-2 infection: low detection rate of anti-nucleocapsid antibodies via Euroimmun ELISA.

PURPOSE: Antibody assays against SARS-CoV-2 are used in sero-epidemiological studies to estimate the proportion of a population with past infection. IgG antibodies against the spike protein (S-IgG) allow no distinction between infection and vaccination. We evaluated the role of anti-nucleocapsid-IgG (N-IgG) to identify individuals with infection more than one year past infection. METHODS: S- and N-IgG were determined using the Euroimmun enzyme-linked immunosorbent assay (ELISA) in two groups: a randomly selected sample from the population of Stuttgart, Germany, and individuals with PCR-proven SARS-CoV-2 infection. Participants were five years or older. Demographics and comorbidities were registered from participants above 17 years. RESULTS: Between June 15, 2021 and July 14, 2021, 454 individuals from the random sample participated, as well as 217 individuals with past SARS-CoV-2 infection. Mean time from positive PCR test result to antibody testing was 458.7 days (standard deviation 14.6 days) in the past infection group. In unvaccinated individuals, the seroconversion rate for S-IgG was 25.5% in the random sample and 75% in the past infection group (P = < 0.001). In vaccinated individuals, the mean signal ratios for S-IgG were higher in individuals with prior infection (6.9 vs 11.2; P = < 0.001). N-IgG were only detectable in 17.1% of participants with past infection. Predictors for detectable N-IgG were older age, male sex, fever, wheezing and in-hospital treatment for COVID-19 and cardiovascular comorbidities. CONCLUSION: N-IgG is not a reliable marker for SARS-CoV-2 infection after more than one year. In future, other diagnostic tests are needed to identify individuals with past natural infection.

Enriching a randomized controlled treatment trial for anorexia nervosa by lived experience-Chances and effects of a lived experience council in the SUSTAIN study.

BACKGROUND: The development and advancement of treatment and care options is one priority in the field of eating disorders. The inclusion of persons with lived experience with eating disorders into clinical research could enrich and accelerate this endeavor, as they can add different perspectives on the disease and its treatment. Although lived experience perspectives are increasingly part of eating disorder research, they have not been widely or structurally implemented into clinical trials and there is limited information on the practice of participatory research, its framework and consequences. AIMS: The present work outlines the participatory collaboration with a lived experience council in the randomized controlled treatment trial SUSTAIN. MATERIALS & METHODS: The manuscript is a participatory publication co-written by individuals with lived experience with anorexia nervosa and eating disorder researchers. RESULTS: We report on motivations for this approach, our collaboration principles, structures and shared experience of working together in the trial, the potential burdens and benefits related to participation for people with lived experience. DISCUSSION: We outline future directions and perspectives to integrate a participatory framework into clinical eating disorder research. CONCLUSION: The involvement of people with experiential knowledge is complex, but possible in clinical research on ED and bears huge potential for the development of more effective care. PUBLIC SIGNIFICANCE: Incorporating perspectives of people with lived experience into a participatory framework of mental health research bears huge potential on a societal level. This includes more relevant research topics and designs, more tailored and effective interventions, and facilitated implementation, as well as dissemination, higher credibility, destigmatization of mental illness, and patient empowerment. Participatory clinical research, however, needs structural anchorage within science and society.

Food-related reward sensitivity across the spectrum of body weight and impulsive eating: Pilot findings from a multi-method approach.

Overweight with and without comorbid binge-eating disorder (BED) has been associated with increased reward sensitivity, though evidence is heterogeneous. To disentangle this heterogeneity and gain insights into mechanisms of impaired reward processing, this study applied multi-method neuro-behavioural techniques. Reward sensitivity was investigated in N = 49 participants allocated to three subgroups: overweight individuals with BED (BED+, n = 17), overweight individuals without BED (BED-, n = 15), and normal-weight controls (NWC, n = 17). Applying a free exploration paradigm (food vs. non-food stimuli), eye tracking and electroencephalographic data were gathered. A valid cue before stimulus onset indicated the position of food, and the end points analysed after the cue and stimulus onset were attentional approach, attention allocation, and conflict processing (e.g., conflict between looking at the potentially rewarding food stimulus or not). The effect of negative mood was tested using mood induction. The study's main hypothesis was that individuals with overweight, particularly under negative mood, would have increased food-related reward sensitivity. All participants showed increased food-specific attentional approach (p < .001). BED + allocated more attention to food stimuli than non-food stimuli compared to the healthy control (p = .045). For individuals with overweight but without BED (BED-), results indicate that conflict processing might be prolonged after the stimulus onset (p = .011). No group-specific effect of negative mood was found. Preliminary results in overweight individuals with and without comorbid BED suggest that food stimuli are generally rewarding stimuli, but even more so for participants with binge eating psychopathology. Prolonged conflict processing during the confrontation with competing food and non-food stimuli was solely found in the BED- sample and might indicate a compensation mechanism. Replication is warranted. The multi-method approach seems to be promising to give indications for the development of psychotherapeutic treatment.

Mind the gap - A brief echo and some contributions from eating disorder experts from other European countries.

Recently, Davey et al. (2023) outlined several recommendations for future care, policy and research for patients with eating disorders which is primarily focused on the UK health care system. Our commentary aims at contributing several aspects from other European countries and emphasises the need for stronger European collaboration, joint initiatives and a strategic plan to foster clinical and research concepts in the eating disorder field, especially in a time of multiple (global) crises and restricted resources.

Barriers and facilitators affecting treatment uptake behaviours for patients with eating disorders: A systematic review synthesising patient, caregiver and clinician perspectives.

OBJECTIVE: A significant treatment gap exists between persons affected by eating disorders (ED), and those engaging with treatment services. This systematic review aims to provide a thorough understanding of the barriers and facilitators affecting eating disorder treatment engagement, including a synthesis of the perspectives of patients, caregivers and healthcare professionals. METHOD: This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies were retrieved from three databases (PubMed, PsycInfo, Web of Science) and were screened and assessed independently by two raters. A thematic analysis was completed to determine the key barriers and facilitators reported by the included studies. RESULTS: A total of 73 studies were included. From these studies, 12 barriers and 13 facilitators were identified. Patients reported stigma, shame and guilt as the most prominent barrier affecting their engagement with treatment services. Meanwhile, caregivers and healthcare professionals reported a lack of eating disorder knowledge of clinicians as the most important barrier. Positive social support was cited as the most prominent facilitator to promote help-seeking. DISCUSSION: Patients, caregivers and healthcare professionals experience a variety of barriers and facilitators to treatment uptake for ED. Interventions addressing barriers and facilitators could increase treatment engagement, including anti-stigma campaigns and positive peer-support interventions.

Behavioural biases in the interaction with food objects in virtual reality and its clinical implication for binge eating disorder.

Cognitive processes play a central role in the development, maintenance and remission in mental disorders, like in Binge Eating Disorder (BED). Insights into cognitive mechanisms reflected by embodied interaction with food and its connections to clinically relevant psychopathology offer new possibilities for translational diagnostics and interventions. We longitudinally investigated the manual interaction with food in a virtual reality (VR) in 31 patients with BED. Patients were assessed at baseline before participating in a randomized-controlled trial (RCT) investigating a computer-based inhibitory control training programme enhanced by transcranial direct current stimulation (tDCS) and at a 6-week follow-up. At both assessments, an experimental VR paradigm was conducted and patients were characterized concerning eating disorder psychopathology, eating behaviour, general impulsivity and food craving. In the experimental task, one of two simultaneously presented objects (food vs. office tools) had to be collected. Food was recognized faster than office tools and subsequent approach behaviour was initiated faster, whereas thereafter, food was collected slower than office tools. Exploratory, we could not find a modulatory effect of applied tDCS on the interaction with food. No relationship between behavioural biases and sample characterizations could be detected. Two different stages in the manual interaction with food were found: a faster first stage that comprises recognition and movement initiation and a slower second stage that comprises controlled handling and may reflect aversive motivational processes. As the behavioural patterns do not change with an ameliorated BED-psychopathology at the second assessment, the task seems insensitive in detecting translational interconnections between behavioural biases and BED-characteristics.Level of evidence: Level I, experimental study.

Mentalization-enhancing therapeutic interventions in the psychotherapy of anorexia nervosa: An analysis of use and influence on patients' mentalizing capacity.

OBJECTIVE: Improvement in patients' mentalizing capacities is considered a possible mechanism of change in psychotherapy. This improvement might take place via mentalization-enhancing interventions (MEIs) performed by psychotherapists. The study aimed to explore the use of MEIs in two evidence-based psychotherapeutic treatments for patients with anorexia nervosa (enhanced cognitive-behavior therapy, focal psychodynamic therapy) and their association with the patients' capacity to mentalize in sessions ("in-session reflective functioning" / in-session RF). Additionally, it was explored, if the amount of MEIs used could either predict change in in-session RF or outcome (end of treatment, one year follow-up). METHOD: 84 audiotapes from psychotherapy sessions of 28 patients of the ANTOP-study (three sessions per patient) were transcribed and rated with both the MEI Rating Scale and the In-Session RF Scale by trained raters. RESULTS: MEIs were applied in both treatments. A moderate correlation between the amount of MEIs and patients' in-session RF as well as its change over the course of treatment was found, but no relation to change in BMI or eating disorder symptoms. CONCLUSION: A greater use of MEIs was related to patients' in-session-mentalizing. However, there seems to be no simple relation between RF as shown in sessions and symptom change.

Does Exercise Modality Matter Affectively? Contrasting Type and Sequence of Moderate-Intensity Continuous Training Versus High-Intensity Interval Training in a Randomized Within-Subject Study.

Over the past two decades, affective determinants of exercise behavior have received increasing attention in research on health promotion and prevention. To date, however, little is known about changes in affective exercise determinants during multi-week training programs in insufficiently active individuals. This applies in particular to the currently discussed advantages and disadvantages of high-intensity interval training (HIIT) compared with moderate-intensity continuous training (MICT) with regard to the affective experience of these two training types (e.g., reduced monotony vs. more aversive response during HIIT), which is important for exercise adherence. Referring to the Affect and Health Behavior Framework (AHBF), this within-subject study investigated changes in affective exercise determinants as a function of training type and sequence consisting of MICT and HIIT. Forty insufficiently active healthy adults (M age = 27 ± 6 years; 72% women) underwent two 6-week training periods in a randomized sequence (MICT - HIIT vs. HIIT - MICT) within 15 weeks. Pre-post questionnaires and in-situ measurements, during and after a standardized vigorous-intensity continuous exercise session (VICE), were used to assess affective attitude, intrinsic motivation, in-task affective valence, as well as post-exercise enjoyment. These four affect-related constructs were collected before, between, and after the two training periods. Mixed models revealed a significant effect for training sequence (p = 0.011) - but not for training type (p = 0.045; non-significant after Bonferroni alpha adjustment) - on changes in in-task affective valence in favor of the MICT - HIIT sequence. Moreover, no significant training type or sequence effects were found for the constructs of reflective processing: exercise enjoyment, affective attitude, and intrinsic motivation. Therefore, individual-based training recommendations should consider the effects of variety and training sequence to develop tailored interventions that lead to more positive affective experiences - in particular during exercise - and promote the maintenance of exercise behavior in previously inactive individuals.

Screening instruments for eating disorders in pregnancy: Current evidence, challenges, and future directions.

Pregnancy is a vulnerable period for eating disorder (ED) occurrence and maternal EDs are associated with heightened risk of adverse pregnancy and infant outcomes. This highlights the need to identify pregnant women with past or current EDs in order to offer appropriate support. However, there is a knowledge and practice gap on screening pregnant women for EDs. Clinical guidance is lacking in international treatment guidelines, which is unsurprising given that no validated ED screening tool specifically designed for use in antenatal populations exists. Moreover, data on the effectiveness of general population screening tools for identifying EDs in pregnant women are scarce. This article provides a synthesis of current evidence, treatment guidelines, and data on the diagnostic accuracy for screening for EDs in antenatal samples from three studies with different screening approaches. We outline recommendations for future steps to tackle the knowledge and practice gap on screening for EDs in pregnant women, including next steps for the development of a pregnancy-specific ED screener and the use of general mental health screeners to detect EDs during pregnancy. Up-to-date, the jury is still out as how to best identify current or past EDs in pregnancy. More research is needed to assess the efficacy of using general mental health screeners versus ED-specific screening instruments to detect ED in pregnancy. Additionally, clinicians have to be trained on how to assess and manage EDs during pregnancy. PUBLIC SIGNIFICANCE: Identifying pregnant women with eating disorders (EDs) is a public health concern which can be addressed using multiple approaches, including implementation of general and specific assessments within routine antenatal care, and training of healthcare professionals.

Maternal eating disorder severity is associated with increased latency of foetal auditory event-related brain responses.

OBJECTIVE: Maternal eating disorders (EDs) are associated with adverse pregnancy and child outcomes. There is limited research investigating the influence of maternal EDs on foetal brain development. METHOD: Using foetal magnetoencephalography (fMEG), an auditory sequence was presented for 10 min to assess brain response latencies in foetuses of mothers with (n = 12) and without (n = 11) a history of anorexia nervosa (AN) in the third trimester of pregnancy. ED history and severity were assessed using the structured clinical expert interview eating disorder examination (EDE) and the self-report questionnaire EDE-Q. RESULTS: Foetuses of mothers with AN showed delayed foetal brain responses to auditory stimulation compared to foetuses of control women. Self-reported ED symptom severity explained 34% of variance in foetal brain response latencies in the AN group. CONCLUSIONS: ED pathology was strongly associated with foetal brain response latencies in the third trimester with longer latencies in foetuses of women with a history of AN reporting more ED symptoms. Follow-up on the children is pivotal to investigate if fMEG outcomes are associated with later child development.

[Information about Eating Disorders - the perspective of relatives]. / Informationsbedarf bei Essstörungen ­ die Angehörigenperspektive.

Objectives: This qualitative study aimed to assess the need for information in eating disorders from the perspective of relatives. Further, it examined the question how publicly available information about eating disorders may contribute to psychoeducation. Methods: Thirteen relatives of patients with anorexia nervosa and bulimia nervosa were interviewed based on a semistructured interview guide. The interview transcripts were interpreted by using a structuring qualitative content analysis. Results: Relatives showed a high need for information throughout the entire course of illness. More information about the disorder itself and its potential treatment were requested. The needs were addressed to public services and to family doctors as well as paediatricians. Conclusions: Relatives as well as family doctors and paediatricians play an important role in the detection and support of the treatment of eating disorders. In view of the high rate of cases diagnosed late or not at all, psychoeducational offers require further expansion.

Combined antisaccade task and transcranial direct current stimulation to increase response inhibition in binge eating disorder.

Binge eating disorder (BED) is associated with deficient response inhibition. Malfunctioning response inhibition is linked to hypoactivation of the dorsolateral prefrontal cortex (dlPFC), where excitability could be increased by anodal transcranial direct current stimulation (tDCS). Response inhibition can be assessed using an antisaccade task which requires supressing a dominant response (i.e. saccade) towards a newly appearing picture in the visual field. We performed a double-blind, randomised, placebo-controlled proof-of-concept-study in which we combined a food-modified antisaccade task with tDCS in people with BED. We expected task learning and modulatory tDCS effects. Sixteen people were allocated to a 1 mA condition, 15 people to a 2 mA condition. Each participant underwent the food-modified antisaccade task at three measurement points: baseline without stimulation, anodal verum and sham stimulation at the right dlPFC in a crossover design. The error rate and the latencies of correct antisaccades decreased over time. No tDCS effect on the error rate could be observed. Compared to sham stimulation, 2 mA tDCS decreased the latencies of correct antisaccades, whereas 1 mA tDCS increased it. Self-reported binge eating episodes were reduced in the 2 mA condition, while there was no change in the 1 mA condition. Participants demonstrated increased response inhibition capacities by a task learning effect concerning the error rate and latencies of correct antisaccades over time as well as a nonlinear tDCS effect represented by ameliorated latencies in the 2 mA and impaired latencies in the 1 mA condition. The reduction of binge eating episodes might indicate a transfer effect to everyday life. Given that the reduction in binge eating was observed before tDCS administration, this effect could not be the result of neuromodulation. Randomized clinical trials are needed to fully understand this reduction, and to explore the efficacy of a combined antisaccade and tDCS training for BED.

The impact of maternal eating disorders on breastfeeding practices: a systematic review.

Breastfeeding is an effective way to protect and promote the health of the infant and mother. Cultural, social, economic, medical, or psychological factors might interfere with successful breastfeeding. Therefore, maternal eating disorders (EDs) may have detrimental effects on the decision of breastfeeding initiation and on its continuation. There is limited knowledge about the breastfeeding practices of mothers with EDs. We performed a systematic review to generate more evidence in this area. A search was conducted in PubMed and PsycINFO, and several journals were hand searched for relevant publications. Of N = 3904 hits, 13 full texts were included in the qualitative analysis. The findings on total duration of BF between mothers with and without EDs were mixed, but women with EDs showed more negative experiences and emotional problems during BF. There was not enough evidence to conclude on breastfeeding initiation, or on the duration of exclusive breastfeeding. Maternal EDs might have a negative impact on BF practices with possible negative effects on the maternal-child feeding environment. Further studies with comparable data and information on the women's partners' attitudes about breastfeeding are needed.

Eating behaviour and symptom trajectories in patients with a history of binge eating disorder during COVID-19 pandemic.

OBJECTIVE: A history of an eating disorder (ED) might constitute a risk for symptom deterioration and relapse during COVID-19 pandemic. This longitudinal study investigates ED symptom trajectories until the first COVID-19 lockdown in Spring 2020 in patients with a history of binge eating disorder (BED). METHOD: Participants of the randomised-controlled BED treatment trial IMPULS participated in a re-assessment directly after the first COVID-19 lockdown in Germany. We used expert-rated clinical interviews and self-report to investigate binge eating (BE) frequency, ED and general psychopathology, distress, emotion regulation and sense of coherence. Symptom trajectories were analysed for baseline when entering the trial, end of trial participation and the time point directly after lockdown. BE frequency was assessed on a recall basis for 4 weeks directly before lockdown and 4 weeks during lockdown. RESULTS: BE frequency, general ED pathology and depressive symptoms markedly increased after as compared to before the COVID-19 outbreak. Individuals scoring high on reappraisal as emotion regulation strategy and sense of coherence scored lower on general ED pathology. CONCLUSION: Individuals with a history of an ED are at risk for symptom deterioration and relapse during the pandemic. Intervention and service dissemination strategies are needed to support vulnerable groups throughout the pandemic.

Weight bias and linguistic body representation in anorexia nervosa: Findings from the BodyTalk project.

OBJECTIVE: This study provides a comprehensive assessment of own body representation and linguistic representation of bodies in general in women with typical and atypical anorexia nervosa (AN). METHODS: In a series of desktop experiments, participants rated a set of adjectives according to their match with a series of computer generated bodies varying in body mass index, and generated prototypic body shapes for the same set of adjectives. We analysed how body mass index of the bodies was associated with positive or negative valence of the adjectives in the different groups. Further, body image and own body perception were assessed. RESULTS: In a German-Italian sample comprising 39 women with AN, 20 women with atypical AN and 40 age matched control participants, we observed effects indicative of weight stigmatization, but no significant differences between the groups. Generally, positive adjectives were associated with lean bodies, whereas negative adjectives were associated with obese bodies. DISCUSSION: Our observations suggest that patients with both typical and atypical AN affectively and visually represent body descriptions not differently from healthy women. We conclude that overvaluation of low body weight and fear of weight gain cannot be explained by generally distorted perception or cognition, but require individual consideration.

Attention allocation to illness-compatible information discriminates women with active versus weight-recovered anorexia nervosa.

OBJECTIVE: Biased attention for disorder-relevant information plays a crucial role in the maintenance of different mental disorders including eating disorders and might be of use to define recovery beyond symptom-related criteria. METHOD: We assessed attention deployment using eye tracking in a cued choice viewing paradigm to two different categories of disorder-relevant stimuli in 24 individuals with acute anorexia nervosa (AN), 20 weight-recovered individuals with a history of AN (WRAN) and 23 healthy control participants (CG). Picture pairs consisted of a food stimulus or a picture depicting physical activity and a matched control stimulus (household item/physical inactivity). Participants rated the valence of stimuli afterwards. RESULTS: The groups did not differ in initial attention deployment. In later processing stages, AN patients showed a generalized attentional avoidance of food and control pictures as compared to CG, while WRAN individuals were in between. AN patients showed an attentional bias toward physical activity pictures as compared to WRAN individuals, but not the CG. AN individuals rated the food pictures and the pictures showing physical inactivity as less pleasant than the CG, while WRAN individuals were in between. DISCUSSION: Attention deployment is partly changed in WRAN as compared to the acute AN group, especially with regard to a shift away from illness-compatible stimuli (physical activity), and this might be a useful recovery criterion. Valence rating of food stimuli might be an additional useful tool to distinguish between acutely ill and weight-recovered individuals. Attentional biases for illness-compatible stimuli might qualify as a valuable approach to defining recovery in AN.
