Eating disorders and multi-level models of emotion: an integrated model

Self-Esteem and Anxiety as Mediators in the Relationship Between Emotional Intelligence and Eating Disorder Symptoms

This study investigated the relationship between emotional intelligence (EI) and eating disorder symptoms (EDS) by testing the serial mediation model, with self-esteem and anxiety as mediators. A total of 923 participants (61.9% female) aged 15-60 years completed questionnaires assessing their EI, self-esteem, anxiety, and EDS. Correlational analyses were conducted to assess the relationship between the study variables, and a serial mediation analysis was conducted to test the possible mediating role of self-esteem and anxiety in the relationship between EI and EDS. Correlation analyses revealed significant bivariate relationships between EI, self-esteem, and anxiety, but no significant correlation between EI and EDS. The relationship between EI and EDS was serially mediated by self-esteem and anxiety. High levels of EI were associated with higher self-esteem, which, in turn, was associated with lower anxiety and less EDS. The results offer potential mechanisms that could explain the relationship between EI and EDS and highlight the importance of EI in regulating eating behavior through self-esteem and anxiety.

Risk and resilience in eating disorders: differentiating pathways among psychosocial predictors

OBJECTIVE

Eating disorders (EDs) represent a rising global health concern. The current study takes a multivariate approach to examine psychological (i.e., perfectionism, anxiety sensitivity [AS], emotion dysregulation) and sociocultural factors (i.e., body dissatisfaction) that may relate to risk and resilience in EDs.

METHODS

Participants were 698 undergraduate students (Mage = 21, SDage = 4.02), mainly female (71%) and Hispanic (61.6%), who participated in an online survey assessing perfectionism, emotion dysregulation, AS, body dissatisfaction, and eating behaviors.

RESULTS

The results from structural equation model analyses revealed differential associations with disordered eating (DE) outcomes. Self-oriented perfectionism and dysmorphic appearance concerns were associated with increased dieting/carb restriction, desire for thinness, and binging tendencies. Specifically, emotional nonacceptance and lack of emotional awareness showed associations with elevated risk for dieting/carb restriction and purging tendencies, respectively. Conversely, lack of emotional clarity showed a protective pathway to these risk behaviors. Anxiety sensitivity cognitive concerns related to higher purging tendencies, while AS social concerns related to lower purging and binging tendencies.

DISCUSSION

Findings highlight the differential pathways of psychosocial risk and resilience for EDs. Subscales of emotional dysregulation and AS showed risk as well as resilience associations with DE outcomes. This information is key for advancing transdiagnostic prevention and intervention to reduce the rising rates of EDs.

The continuation of non-physical abuse from childhood to adulthood in eating disorder patients: An interpretative phenomenological analysis

BACKGROUND

The ED literature has focused on the physical forms of childhood abuse with respect to eating disorders, overlooking non-physical abuse even though eating disorder patients report the latter either as primary experiences or as a revival of their childhood experiences. Additionally, there is no literature exploring whether adult eating disorder patients who have experienced childhood non-physical abuse continue to experience abuse as adults, and if they do, how well-being is impacted or linked with eating pathology.

OBJECTIVE

This study explored the lived experiences of eating disorders patients who have experienced non-physical childhood abuse in childhood and adulthood.

PARTICIPANTS AND SETTINGS

Six adult female eating disorder outpatients each took part in a semi-structured interview.

METHODS

This study used the Interpretative Phenomenological Analysis framework.

RESULTS

Three master themes and eleven superordinate themes were drawn from the analysis, addressing the research question: continuation of non-physical abuse across a lifetime, developmental factors and non-physical abuse, and non-physical abuse and eating pathology.

CONCLUSIONS

The participants' accounts indicate that childhood non-physical abuse is related to eating disorder onset, and abuse continuation in adulthood contributes to the disorder's maintenance. Moreover, the lifelong consequences of non-physical childhood abuse impact psychological factors, such as self-esteem, attachment and emotion regulation, affecting the individuals' adult lives and keeping participants inside a vicious cycle of trauma re-enactment. Low self-esteem is considered by the participants as the key factor for their disturbed relationship with food.

"I cannot see your fear!" Altered recognition of fearful facial expressions in anorexia nervosa

Background

The evidence about facial emotion recognition in anorexia nervosa as the role of alexithymic traits on this emotional ability is conflicting and heterogeneous.

Objective

We assessed the capability of recognizing facial expressions of two primary emotions, fear, and anger, in the context of anorexia nervosa.

Methods

Women affected by anorexia nervosa were compared with healthy weight women in a well-established implicit facial emotion recognition task. Both reaction time and level of accuracy were computed. Moreover, the individual levels of alexithymia were assessed through a standard self-report questionnaire.

Results

Participants with anorexia nervosa reported a significantly lower performance in terms of reaction time and accuracy when the emotion of fear-but not anger-was the target. Notably, such an alteration was linked to the levels of alexithymia reported in the self-report questionnaire.

Conclusion

In anorexia nervosa, difficulties in processing facial fearful (but not angry) expressions may be observed as linked to higher expressions of alexithymic traits. We suggested future research in which emotional processing will be investigated taking into account the role of the bodily dimensions of emotional awareness.

The effect of imagery rescripting on core beliefs and eating disorder symptoms in a subclinical population

BACKGROUND AND OBJECTIVES

This study compared the effect of imagery rescripting focusing on self-compassion, imagery rescripting focusing on mastery, and a positive memory control condition on (1) emotional responses towards the memory (one day after), (2) changes in the believability of negative core beliefs, and dysfunctional eating behaviors (one week after) in individual at risk for developing an eating disorder.

METHODS

Female participants (N = 69) were allocated to one of three conditions: ImRs focusing on self-compassion (N = 24), ImRs focusing on self-mastery (N = 23), and positive memory control condition (N = 22). Participants in the ImRs conditions received a 20-min self-guided ImRs intervention, whereas participants in the control condition received a 20-min self-guided task focusing on an unrelated positive memory.

RESULTS

The experimental manipulation successfully induced the use of self-compassion and mastery strategies in the respective imagery rescripting condition. However, our data show that a single 20-min session of self-guided imagery rescripting focusing on compassion and/or mastery has no effect on the emotional response towards the aversive memory or in the change of core beliefs and eating behaviors at follow up.

LIMITATIONS

We discuss potential reasons for the null findings, including the use of a single imagery rescripting session, the sample size and the measurement of manipulation checks.

CONCLUSION

Future studies are needed to rule out methodological explanations for the null results. These findings may be of value for the development of future experimental lab paradigms which aim to evaluate the causal effects and working mechanisms of imagery rescripting.

Subjective disgust and facial electromyography responses towards unedited and morphed overweight self-pictures in women with varying levels of eating disorder symptomatology

Individuals with an eating disorder (ED) often report to be disgusted by their body. Body-related self-disgust could play an important role in the development and maintenance of EDs. We investigated if women with relatively high ED symptom scores indeed respond with disgust upon exposure to their body as indexed by facial electromyography (fEMG) of the m. levator labii superioris and self-report. Given that one's self-disgust may increase/decrease depending on the relative distance of the own body to the thin ideal, we also assessed women's disgust for overweight- and thin-morphs of their body. Female undergraduate students (N = 104) were photographed and presented with their (morphed) body pictures, next to disgust-relevant and overweight body control pictures. Higher levels of ED symptoms were associated with stronger self-reported disgust to unedited body-pictures and overweight-morphs. Disgust to thin-morphs was unrelated to ED symptoms. Participants generally showed heightened facial disgust towards overweight morphs, yet the strength of facial disgust was unrelated to ED symptoms. Thus, the findings provide evidence for the involvement of heightened body-related self-disgust in ED symptomatology, albeit only on the basis of self-report.

A machine learning investigation into the temporal dynamics of physical activity-mediated emotional regulation in adolescents with anorexia nervosa and healthy controls

OBJECTIVE

Anorexia nervosa (AN) is commonly experienced alongside difficulties of emotion regulation (ER). Previous works identified physical activity (PA) as a mechanism for AN sufferers to achieve desired affective states, with evidence towards mitigation of negative affect. However, temporal associations of PA with specific emotional state outcomes are unknown.

METHOD

Using lag-ensemble machine learning and feature importance analyses, 888 affect-based ecological momentary assessments across N = 75 adolescents with AN (N = 44) and healthy controls (N = 31) were analysed to explore significance of past PA, measured through passively collected wrist-worn actigraphy, with subsequent self-report momentary affect change across 9 affect constructs.

RESULTS

Among AN adolescents, later lags (≥2.5 h) were important in predicting change across negative emotions (hostility, sadness, fear, guilt). AN-specific model performance on held-out test data revealed the holistic "negative affect" construct as significantly predictable. Only joviality and self-assurance, both positively-valenced constructs, were significantly predictable among healthy-control-specific models.

DISCUSSION

Results recapitulated previous findings regarding the importance of PA in negative ER for AN individuals. Moreover, PA was found to play a uniquely prominent role in predicting negative affect 4.5-6 h later among AN adolescents. Future research into the PA-ER dynamic will benefit from targeting specific negative emotions across greater temporal scales.

Shame, Guilt, and Self-Consciousness in Anorexia Nervosa

BACKGROUND

the role of self-conscious emotions (SCE) such as shame and guilt in eating disorders (ED) has been systematically studied only in recent years, but it is still debated. This study aims to investigate the role of SCE in anorexia nervosa (AN), evaluating the role of self-consciousness.

METHODS

fifty-five individuals with AN and seventy-four healthy controls (HC) were enrolled and completed a battery of tests evaluating the proneness to feel shame and guilt, as well as comparing self-consciousness, eating, and general psychopathology.

RESULTS

individuals with AN showed a higher proneness to shame. Shame was correlated with body dissatisfaction and drive for thinness, which are core symptoms in AN, after controlling for scores of depression and anxiety. Proneness to guilt seemed to be less correlated with eating and body symptomatology, but it appeared to have a negative correlation with binge-purging symptoms. Furthermore, proneness to shame was independent of guilt or self-consciousness and the two groups did not differ regarding public and private self-consciousness.

CONCLUSIONS

shame is an important and independent factor in AN. Future research may offer progress in the development of shame-focused therapies.

A piece of a puzzle-Patient and psychologist experiences of the Affect School as additional treatment in a Swedish eating disorder unit

BACKGROUND

Emotion dysregulation has been shown to be a transdiagnostic characteristic of eating disorders. The Affect School aims to enhance emotional awareness and the ability to perceive and express emotions. This study was conducted as part of an RCT where patients with various eating disorders were randomised to participation in the Affect School as a supplement to treatment.

AIM

To explore Affect School participants' and leaders' experiences of the Affect school at an Eating Disorder outpatient unit in Sweden.

METHOD

Nine patients with eating disorder diagnoses and three Affect School leaders at an eating disorder outpatient clinic in Sweden were interviewed for their experiences of the intervention. The interviews were analysed with Thematic Analysis.

RESULT

Eight themes were revealed at the analysis, five from the participants: "Worries about group participation", "Not alone anymore and gaining new insights about oneself", "Shared stories can also be painful", "Relationships outside the Affect School as a foundation for affective work", and "A change is coming", and three from the leaders:"Affect awareness is important in eating disorders", "Group meetings create opportunities and challenges", and "The Affect School setup needs more customisation".

CONCLUSION

The results suggested that the Affect School provided an acceptance for experiencing all sorts of affects. Both leaders and participants considered working with affects necessary, although participants reported no changes in their life situation or condition after the intervention but considered the intervention as part of a process with gradual results. Being part of a group and sharing experiences was experienced as positive by participants and leaders, but the model could be further developed to better adapt to patients with an eating disorder.

'The last thing you feel is the self-disgust'. The role of self-directed disgust in men who have attempted suicide: A grounded theory study

OBJECTIVE

Globally, suicide affects more men than women. Emotional pain underpins many theoretical accounts of suicidality, yet little is known about the role of disgust in suicide. Self-directed disgust, whereby aspects of the self-serve as an object of disgust, has been hypothesised to factor in suicide. This research aimed to explore the processes which link self-disgust to attempted suicide in males.

METHOD

Nine men who had attempted suicide completed semi-structured interviews. The interview data were analysed using a constructivist grounded theory methodology.

RESULTS

Three concepts emerged out of the analysis: (1) self-disgust; (2) worthlessness; and (3) the endured emotional distress of 'the abyss'" - these concepts interweaved, leading the men to experience hopelessness, disconnection and an inability to cope, leading ultimately to their suicide attempt. Throughout this journey, various disgust-related processes worsened men's distress and increased their suicidal risk. Historic adversities prevailed across the data, as did the men's difficulties in understanding their emotions.

CONCLUSION

Self-disgust was an important emotion in the men's experiences of suicide and shaped their views of themselves and their lives. The distancing and repellent properties of self-disgust, in addition to the fear of having their 'disgustingness' exposed, increased suicidal risk. Self-disgust appeared more pervasive in the suicidality of men with a history of multiple childhood adversities. The limitations of this research are discussed as implications for clinical practice and directions for future research.

Evaluation of the Affect School as supplementary treatment of Swedish women with eating disorders: a randomized clinical trial

BACKGROUND

Despite solid research there remains a large group of patients with eating disorders who do not recover. Emotion dysregulation has been shown to be a feature in the different eating disorders. A manualized group intervention developed in Sweden, the Affect School, aims to enhance emotional awareness and the ability to perceive and express emotions.

AIM

This study aimed to test the hypothesis that participation in the Affect School as a complement to ordinary eating disorder treatment would enhance awareness and regulation of emotions and reduce alexithymia and cognitive eating disorder symptoms in a sample of patients with eating disorders at a Swedish specialized outpatient clinic.

METHOD

Forty patients with various eating disorders were randomized to either participation in the Affect School as a supplement to treatment as usual (TAU), or to a TAU control group. Participants were assessed with the Eating Disorder Examination Questionnaire, the Deficits in Emotion Regulation Scale-36, and the Toronto Alexithymia Scale-20 at start, end of intervention, and at the 6- and 12-month follow-ups.

RESULTS

No significant differences were observed post-treatment but Affect School participants had improved significantly more than controls on eating disorder cognitions and behaviours and emotion dysregulation at the 6- and 12-month follow-ups and had significantly less alexithymia at the 6-month follow-up.

CONCLUSION

Difficulties with emotion recognition and/or regulation can complicate fulfilment of personal needs and obstruct communication and relationships with others. The present study indicates that adding Affect School group sessions to regular treatment enhances emotional awareness and emotion regulation and decreases eating disorder symptoms and alexithymia. Patients with eating disorder diagnoses have described problems with emotional management, for example: lower emotional awareness and difficulties in using adaptive emotional regulatory strategies compared to people without eating disorders. It has been suggested that interventions aiming at enhancing emotional awareness and acceptance would be beneficial in treatment. In the present study we explored whether adding the Affect School to regular treatment would enhance awareness and regulation of emotions and decrease eating disorder symptoms. Forty women with an eating disorder were randomly allocated to either an additional participation in a group treatment for 8 weeks or usual treatment only. The treatment contained education on different affects such as joy, fear, interest, shame, anger, disgust, and worry. The education was followed by discussions on own experiences. Participants filled in self-assessment forms that measured eating disorder symptoms, emotional recognition, and emotion regulation before the start and at the end of the group treatment, and after 6 and 12 months respectively. The results when comparing the two groups suggested that the Affect School could be an effective additional treatment. Participants in the Affect School improved their scorings but the change took time and did not show until at the 6- and 12 months follow-ups.

Revisiting alexithymia as an important construct in the treatment of anorexia nervosa: a proposal for future research

Consistent research supports altered emotional processing in adult patients with anorexia nervosa (AN), including elevations in alexithymia, or deficits in identifying and describing emotions and other internal experiences. Despite increasing interest in emotion-focused therapies for AN, alexithymia is often not directly addressed within many existing treatments, and little empirical work has moved beyond descriptive, cross-sectional research. In this paper, we propose that refining the field's understanding of alexithymia may provide insights into poor outcomes in existing psychological treatments for AN. First, we provide a brief overview of existing work exploring alexithymia in AN, and then describe several next steps in treatment-relevant research, including differentiating alexithymia from related constructs, considering neurobiological correlates of alexithymia, testing the link between alexithymia and outcome across treatment modalities, and piloting adjunctive treatment techniques focused on emotional identification and description. Altogether, exploring adjunctive treatment approaches targeting alexithymia may offer one promising possibility for improving long-term outcomes.

Determining the Intensity of Basic Emotions among People Suffering from Anorexia Nervosa Based on Free Statements about Their Body

Objective: This study sought to address one of the challenges of psychiatry-computer aided diagnosis and therapy of anorexia nervosa. The goal of the paper is to present a method of determining the intensity of five emotions (happiness, sadness, anxiety, anger and disgust) in medical notes, which was then used to analyze the feelings of people suffering from anorexia nervosa. In total, 96 notes were researched (46 from people suffering from anorexia and 52 from healthy people). Method: The developed solution allows a comprehensive assessment of the intensity of five feelings (happiness, sadness, anxiety, anger and disgust) occurring in text notes. This method implements Nencki Affective Word List dictionary extension, in which the original version has a limited vocabulary. The method was tested on a group of patients suffering from anorexia nervosa and a control group (healthy people without an eating disorder). Of the analyzed medical, only 8% of the words are in the original dictionary. Results: As a result of the study, two emotional profiles were obtained: one pattern for a healthy person and one for a person suffering from anorexia nervosa. Comparing the average emotional intensity in profiles of a healthy person and person with a disorder, a higher value of happiness intensity is noticeable in the profile of a healthy person than in the profile of a person with an illness. The opposite situation occurs with other emotions (sadness, anxiety, disgust, anger); they reach higher values in the case of the profile of a person suffering from anorexia nervosa. Discussion: The presented method can be used when observing the patient’s progress during applied therapy. It allows us to state whether the chosen method has a positive effect on the mental state of the patient, and if his emotional profile is similar to the emotional profile of a healthy person. The method can also be used during first diagnosis visit.

'In an otherwise limitless world, I was sure of my limit.'† Experiencing Anorexia Nervosa: A phenomenological metasynthesis

Anorexia Nervosa (AN) has the highest mortality rate of the mental disorders, with still less than 50% of affected individuals achieving recovery. Recent calls to bring innovative, empirical research strategies to the understanding of illness and its core psychopathological features highlight the need to address significant paucity of efficacious treatment. The current study brings a phenomenological approach to this challenge, synthesizing lived experience phenomena as described by qualitative literature. Fifty-three studies published between the years 1998 and 2021 comprising a total of 1557 participants aged 12-66 suffering from AN or sub-threshold AN are included. Reciprocal and refutational analysis generated six key third-order constructs: "emotion experienced as overwhelming," "identity," "AN as a tool," "internal conflict relating to Anorexia," "interpersonal communication difficulties" and "corporeality." Twenty-six sub-themes were identified, the most common being fear, avoidance, AN as guardian/protector, and AN as intertwined with identity. Some themes associated with current treatment models such as low self-esteem, need for social approval and feelings of fatness were less common. We highlight the significant role of intense and confusing emotion in AN, which is both rooted in and engenders amplified fear and anxiety. Restrictive eating functions to numb these feelings and withdraw an individual from a chaotic and threatening world whilst providing a sense of self around which to build an illness identity. Results have implications for therapeutic practice and overly protective weight and shape focused medical treatment models, which may serve to reinforce the disease.

Emotion regulation in adolescents with anorexia and bulimia nervosa: Differential use of adaptive and maladaptive strategies compared to healthy adolescents

OBJECTIVE

Adolescents with anorexia (AN) and bulimia nervosa (BN) often struggle with emotion regulation (ER). These difficulties have predominantly been assessed across emotions, without considering adaptive and maladaptive ER separately. We compared adolescents with AN or BN to healthy adolescents (HCs) regarding the adaptive and maladaptive ER of three emotions.

METHOD

A treatment-seeking sample of 197 adolescents (atypical/full-threshold AN: N = 118, atypical/full-threshold BN: N = 32; HC: N = 47) reported emotion-specific ER with the FEEL-KJ questionnaire. Mixed models were calculated for adaptive and maladaptive ER to assess differences between emotions (anxiety, anger, and sadness) and groups (AN, BN, and HC).

RESULTS

Main effects of emotion (p < .001) and group (p < .001) were found, but no interaction effects were found (p > .05). Post hoc tests showed lower maladaptive and higher adaptive ER for anxiety than anger or sadness (p < .001). AN and BN reported lower adaptive (p < .001) and higher maladaptive ER than HCs (p < .001). BN showed the highest levels of maladaptive ER (p = .009).

DISCUSSION

The differences between AN and BN in adaptive and maladaptive ER should be considered. Furthermore, investigating differences in ER of other emotions in eating disorders might be promising.

Self-disgust and urge to be thin in eating disorders: how can self-compassion help?

PURPOSE

This study aimed to examine the moderator role of self-compassion in the relationship between self-disgust and drive for thinness, controlling for external shame, in eating disorder patients and in a community sample.

METHODS

Sixty-two female participants with an eating disorder diagnose and 119 female participants from the community, were asked to fill instruments that assess self-disgust, self-compassion, drive for thinness, and external shame.

RESULTS

We found a moderator effect of self-compassion on the association between self-disgust and drive for thinness in the clinical sample when adjusting for shame. The association between self-disgust and drive for thinness was buffered among those who reported medium and lower levels of self-compassion. Replicating the findings in the community sample we found no moderator effect of self-compassion.

CONCLUSION

These results provide evidence that people with eating disorders who perceive the self as highly disgusting may benefit from promoting a self-compassionate response to diminish drive for thinness.

LEVEL OF EVIDENCE

Level V, cross-sectional descriptive study.

Eating for numbing: a community-based study of trauma exposure, emotion dysregulation, dissociation, body dissatisfaction and eating disorder symptoms

Objective

The current study tests the relationship between eating disorder (ED) symptoms and trauma exposure. The mechanisms via which trauma is related to ED symptoms have not been sufficiently examined. This study examines the complex role of dissociation and emotional dysregulation in the context of trauma, BMI, ED symptoms and body dissatisfaction (BD). We hypothesized that dissociation and emotional dysregulation would mediate the relationship between trauma exposure and ED symptoms/BD. We further hypothesized that BMI would play a moderating role in this association.

Method

A community sample of 229 (16.2% male) participants, with a mean age of 29.08 ± 10.68 reported online on traumatic events (Life Events Checklist), dissociation (Dissociative Experiences Scale-II), emotional dysregulation (Difficulties in Emotional Regulation Scale), ED symptoms (Eating Disorders Examination-Questionnaire) and BD (Figure Rating Scale).

Results

Participants reported experiencing a mean of 2.87 ± 2.27 traumatic events, with a relatively high percentage (~86%) reporting at least one. The most commonly reported traumatic events were transportation accidents and physical assault. Although frequency of traumatic events did not directly predict ED symptoms, BMI, dissociation, emotional dysregulation and BD did. An SEM model showed that traumatic events predicted ED symptoms indirectly through dissociation, emotional dysregulation and BMI. Dissociation and emotional dysregulation predicted ED symptoms directly. BMI also moderated the association between traumatic events and both ED symptoms and BD.

Conclusions

Therapists treating patients with high BMI or obesity should be aware of these relationships and investigate the possibility that trauma and/or PTSD may underlie the presenting disordered eating or eating disorder.

Positive and Negative Emotional Eating Are Not the Same-The Spanish Version of the Positive-Negative Emotional Eating Scale (PNEES)

The literature points to the importance of distinguishing between positive and negative emotional eating in relation to overeating and binge eating. The aim of this study was to evaluate the Spanish version of the Positive-Negative Emotional Eating Scale (PNEES) in a Spanish community sample. The sample consisted of 628 participants. The mean age was 27.5 (SD = 12.7) and 70.1% of them were women. The participants completed the PNEES, and measures of anxiety and depression (HADS), and eating disorder-related scales (TFEQ-R18, BULIT-R, and EAT-26) that were selected to examine convergent validity. A confirmatory factor analysis was conducted, replicating the original two-factor solution, consisting of Negative Emotional Eating (PNEES-N) and Positive Emotional Eating (PNEES-P). The results showed an acceptable fit of the model (CFI = 0.986; TLI = 0.984, RMSEA = 0.055). Internal consistency ranged from ω = 0.92 to ω = 0.96 for both subscales and the total score. PNEES-P correlations with other variables were lower with respect to the PNEES-N, showing that they are different constructs. A mediation analysis was conducted, in which PNEES-P significantly predicted binge eating and PNEES-N was a partially mediator variable. The results showed that the adaptation process was successful.

Emotional intelligence and eating disorders: a systematic review

BACKGROUND

Prior research indicates that deficits in emotional abilities are key predictors of the onset and maintenance of eating disorders (ED). As a relatively new emotion-related construct, emotional intelligence (EI) comprises a set of basic emotional abilities. Preliminary research suggests that deficits in EI are linked with disordered eating and other impulsive behaviours. Also, previous research reveals that emotional and socio-cognitive abilities, as well as ED symptomatology, varies across lifespan development. However, while the findings suggest promising results for the development of potential effective treatments for emotional deficits and disordered eating, it is difficult to summarise the relationship between EI and ED due to the diversity of theoretical approaches and variety of EI and ED measures.

OBJECTIVE

Our study, therefore, aimed to systematically review the current evidence on EI and ED in both the general and clinical populations and across different developmental stages.

METHODS

The databases examined were Medline, PsycInfo and Scopus, and 15 eligible articles were identified. Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were used.

RESULTS

All the studies reviewed indicated negative associations between EI and the dimensions of ED. Additionally, several mechanisms involved, namely adaptability, stress tolerance and emotional regulation were highlighted.

CONCLUSION

The systematic review suggests promising but challenging preliminary evidence of the associations between EI and the dimensions of ED across diverse stages of development. In addition, future research, practical implications and limitations are discussed.

Just like fireworks in my brain - a Swedish interview study on experiences of emotions in female patients with eating disorders

BACKGROUND

Patients with eating disorders have reported poorer emotional awareness, more emotional suppression, less use of adaptive emotional regulation strategies, and more use of maladaptive emotional regulation strategies compared to people in healthy control groups.

AIM

To explore experiences of emotions by a transdiagnostic sample of patients with eating disorders.

METHOD

Nine patients with different eating disorder diagnoses at an eating disorder outpatient clinic in Sweden were interviewed for their thoughts on emotions. The interviews were analyzed with Thematic Analysis.

RESULT

Four themes were constructed: "Not knowing what one feels", "Switch off, run away, or hide behind a mask", "Emotions in a lifelong perspective", and "Using eating behaviours to regulate emotions". The patients described uncertainty regarding whether they experienced emotions correctly. They described how they tried to avoid difficult emotions through suppressive strategies and eating disorder behaviour. All described strategies were inefficient and all emotions were experienced as problematic, even joy. Since joy was used as a mask, the real experience of happiness was lost and mourned.

CONCLUSION

All kinds of emotions were considered problematic to experience, but shame, fear, and sadness were considered worst. It is difficult to know if the emotional difficulties preceded an eating disorder, however such difficulties may have increased as a result of the eating disorder.

Beyond the Revolving Door: Long-Term Lived Experience of Eating Disorders and Specialist Service Provision

In this study, we undertook a narrative analysis of participants' long-term lived experience of eating disorders and specialist service provision. Eight participants were recruited with service experience across five National Health Service (NHS) Trusts in the United Kingdom. All participants had a minimum of 10 years self-reported experience living with an eating disorder. The data are presented across different temporal stages that demonstrate the development of participants' self-construct in relation to their first contact with specialist services, what had happened in their lives for this to become necessary, and their current relationships with services, before exploring what participants need from services to help them feel heard going forward. Findings suggest that current methods of service delivery result in delayed and inappropriate supports and a consequent "battling" against professionals, which can provide an obstacle to compassionate and collaborative working and promote "revolving door" experiences.

Exploring the Link Between Emotional Child Abuse and Anorexia Nervosa: A Psychopathological Correlation

Eating disorders (ED) are well known psychiatric disorders associated with dysregulated eating behaviors and related thoughts and emotions. Common eating disorders are bulimia nervosa (BN), anorexia nervosa (AN), and binge eating disorders (BED). There is an active link between child abuse and eating disorders, emotional child abuse being the important subtype of CA and has a strong comorbid psychopathological relationship with EDs, including AN. The PubMed database was searched for the related articles about child abuse, including emotional childhood maltreatment and their psychopathology associated with EDs, especially AN. No filters were used for the date of publication and article types. Childhood abuse, including physical, sexual, and emotional maltreatment, has an active link with psychopathology associated with dysregulated eating behaviors. However, emotional childhood maltreatment including emotional abuse, neglect, and/or exposure to intimate partner violence (IPV) has been least studied, but studies have shown a strong relationship with the symptoms of anorexia nervosa such as weight concern, negative self-image, and maladaptive emotional response. Emotional dysregulation is the crucial psychopathological factor involved in mediating the effects of emotional childhood maltreatment and symptoms of anorexia nervosa and is strongly associated with long-term morbidity in patients with AN. Conducting more clinical studies in the future would help explore the temporal causation, and this association may help the practitioners to develop new diagnostic and therapeutic strategies in the management of AN.

Emotional development in eating disorders: A qualitative metasynthesis

Emotions are considered to be an important feature in eating disorders. The present study aimed to conduct a systematic review and metasynthesis of qualitative studies, which considered the role of emotions in eating disorders in order to gain further insight on how these individuals experience various emotions and the strategies they use to manage them. Databases including Web of Science, PsychInfo, EMBASE, Medline, and the Cochrane library were searched for qualitative studies. The search identified 16 relevant studies. Meta-ethnography was used to synthesize the data, which involved identifying the key findings and concepts of the studies and creating metaphors. The synthesis involved reciprocal translations and lines of argument approaches being applied to the present data. Results of the synthesis identified four second-order themes and one third-order theme relating to the emotional experiences of such individuals. The second-order themes were (a) negative emotional environments, (b) interpersonal vulnerability, (c) the experience of negative emotions in social contexts, and (d) the management of emotions. The third-order theme was the emotional self within a social environment. This is the first metasynthesis on emotions and eating disorders, and our synthesis highlights the important role that emotions play in the development and maintenance of eating disorders. Our model demonstrates how poor emotional development whilst growing up results in development of poor socioemotional bonds and the inability to handle negative emotions. The most significant finding of the review is that individuals use their eating disorder to manage negative emotions.

Sex-dependent associations of childhood neglect and bodyweight across the life span

Eating disorders and weight problems across the life span have been linked to adverse childhood experiences. Previous research often focused on child abuse and omitted investigating effects of child neglect. The present study evaluates effects of neglect on bodyweight across the life span and how emotional neglect and bodyweight are linked via mental distress. Within a large survey representative of the German population (N = 2,500), individuals completed measures of mental distress, childhood trauma, and height and weight. We conducted logistic regression analyses on bodyweight extremes and a moderated mediation analysis. In men, physical neglect aggravated the risk to be underweight. In women, emotional neglect was linked to severe obesity. In both sexes, emotional neglect was related to mental distress. We found an indirect effect of emotional neglect on bodyweight via mental distress, however, it was only present in women. Our results attest to long-term consequences of adverse early experiences. We showed a possible mechanism for women’s higher vulnerability towards eating disorders. In general, investigations of eating and weight disorders should also include men and employ sex-specific methods of analyses. Lastly, neglect should also receive more attention to prevent suffering and negative sequelae over the life span.

Disgust, impulsivity and depressive dimensions in subjects at risk for bulimia nervosa and/or binge eating disorder

PURPOSE

the study aims to assess the depressive symptoms, the disgust feeling and the impulsivity index in subjects showing a high risk of binge eating disorder (BED) and/or bulimia nervosa (BN) through a cross-sectional study of 150 participants.

RESULTS

There was no significant difference regarding age, sex, employment and marital status between subjects at high risk for BED/BN (Group A) and controls (Group B). However, participants in group A presented higher scores of depressions (p = 0.021), impulsivity (p = 0.027) and Disgust (p = 0.030) with significant associations.

CONCLUSION

The neurobiological basis for these associations might be related to a dysfunction in the insular cortex.

Low Adherence to the Mediterranean Diet in Isolated Adolescents: The Mediation Effects of Stress

Loneliness perception during adolescence has been increased dramatically in recent years. Changes in lifestyle and difficulties in social interaction could explain this increased phenomenon. As described in previous research, this fact has been associated with the development of high stress levels and dysfunctional lifestyles, in which eating habits play a main role. In this regard, loneliness has been classically associated with poor eating habits, fundamentally the consumption of processed food with little nutritional value. However, the relationship between loneliness and healthy eating patterns, such as the Mediterranean Diet (MD), has not been previously analyzed. The main aim of the present study was to identify the relationship between perceived loneliness, stress, dietary habits, and adherence to the MD in a sample of 527 Spanish adolescents. The obtained results show a significant association between high perceived loneliness and high stress levels with lower MD adherence. Hence, adolescents with high perceived loneliness exhibit poor dietary habits in comparison to those counterparts with low perceived loneliness. Mediation analyses demonstrated an indirect effect of the loneliness on adherence to the MD through the mediation effect of stress. These findings point out a possible mechanism that underlies the classic association between loneliness and health deterioration, based on a poor adherence to a healthy dietary pattern, such as the MD.

Dimensional analysis of emotion trajectories before and after disordered eating behaviors in a sample of women with bulimia nervosa

There is an established relationship between increases in negative affect and engagement in binge eating and purging behaviors. Some evidence suggests that these behaviors may also be maintained via subsequent increases in positive affect. However, negative and positive affect are broad terms encompassing many emotions, and there is a theoretical speculation that every emotion consists of at least of three separate dimensions: valence, arousal, and approach/withdrawal. We conducted secondary analyses on a previously collected dataset using ecological momentary assessment in 133 women with bulimia nervosa. Participants rated their experience of discrete emotions and bulimic behaviors six times per day. Negative and positive emotions were organized within the 3-dimensional space characterized by valence, arousal, and approach/withdrawal. With multilevel modeling, we examined the trajectories of dimensionally defined emotion constructs prior and subsequent to bulimic behaviors as well as on days with and without bulimic behaviors. Negative valence, high arousal, and avoidance typified emotions that reached the highest levels before bulimic behaviors and were at the highest mean levels on days with bulimic behaviors. Arousal did not appear to moderate the trajectories of positive emotions. Application of a dimensional understanding of emotions may help elucidate the complex relationship between mood and disordered eating.

A neural basis for antagonistic control of feeding and compulsive behaviors

Abnormal feeding often co-exists with compulsive behaviors, but the underlying neural basis remains unknown. Excessive self-grooming in rodents is associated with compulsivity. Here, we show that optogenetically manipulating the activity of lateral hypothalamus (LH) projections targeting the paraventricular hypothalamus (PVH) differentially promotes either feeding or repetitive self-grooming. Whereas selective activation of GABAergic LH→PVH inputs induces feeding, activation of glutamatergic inputs promotes self-grooming. Strikingly, targeted stimulation of GABAergic LH→PVH leads to rapid and reversible transitions to feeding from induced intense self-grooming, while activating glutamatergic LH→PVH or PVH neurons causes rapid and reversible transitions to self-grooming from voracious feeding induced by fasting. Further, specific inhibition of either LH→PVH GABAergic action or PVH neurons reduces self-grooming induced by stress. Thus, we have uncovered a parallel LH→PVH projection circuit for antagonistic control of feeding and self-grooming through dynamic modulation of PVH neuron activity, revealing a common neural pathway that underlies feeding and compulsive behaviors.

The Perception of Threat from Emotions in Predicting Binge Eating Behaviours in People Who Are Obese and Seeking Treatment for Their Weight

OBJECTIVE

The affect regulation theory suggests that people binge eat to regulate negative emotional states. In this study, we used a basic emotions perspective to consider the role of perceived threat of emotions, emotional suppression and reduced emotional expressiveness in predicting binge eating behaviours in people who are obese.

METHOD

Treatment-seeking participants with obesity (N = 51, body mass index range from 30.8 to 60.2 kg m^-2 ) completed measures of 'perception of threat from emotion' as well as 'emotional expressiveness' and binge eating.

RESULTS

The results demonstrated that perceived threat of sadness predicted binge eating (β = .55, p < .05). Additionally, a mediation analysis revealed that reduced emotional expressiveness mediated the relationship between perceived threat of fear and binge eating (β = .25, 95%).

DISCUSSION

These findings are contextualized within a theoretical perspective that suggests that individuals who binge eat are threatened by certain emotional states and they use binge eating to suppress certain, but not all, emotional states. Copyright © 2015 John Wiley & Sons, Ltd.

KEY PRACTITIONER MESSAGE

Considering basic emotions within binge eating should be a part of a psychological assessment and treatment. This should consider how emotions could often be perceived as being threatening and their expression is limited. It is possible that the emotions of fear and sadness appear to be particularly threatening within binge eating/obese populations.

Intermittent explosive disorder and eating disorders: Analysis of national comorbidity and research samples

OBJECTIVE

Clinical studies suggest comorbidity between eating disorders and aggressive behaviors. This study examined the pattern of comorbidity between intermittent explosive disorder (IED) and eating disorders (ED).

METHODS

Data were analyzed from both the adult and adolescent samples of the National Comorbidity Survey-Replication (n = 19,430) and a clinical research sample (n = 1,642).

RESULTS

Lifetime prevalence of Any ED was elevated in IED vs. non-IED for both the community and clinical research samples. Though anorexia nervosa displayed no relationship with IED in either sample, bulimia nervosa was associated with IED in the community sample and binge eating disorder was associated with IED in both the community and clinical research samples. Onset of IED preceded onset of Any ED in at least 70% of comorbid IED/ED cases in both community and clinical research samples. Associations of IED with Any ED and bulimia nervosa in the community sample, and associations of IED with binge eating disorder in the clinical research sample, remained significant after controlling for other psychiatric disorders.

CONCLUSIONS

Individuals with IED are more likely to report lifetime prevalence of ED, particularly bulimic spectrum disorders. This finding, and the observation that the onset of IED occurs prior to the onset of ED in the majority of individuals, suggests that longitudinal studies are needed to clarify this relationship and determine whether IED is a risk factor for the development of ED. Early identification of individuals with IED or impulsive aggression may provide clinically useful information to determine most effective treatment interventions.

The role of self-disgust in eating psychopathology in overweight and obesity: Can self-compassion be useful?

This study explores the relationship between self-disgust and eating psychopathology and whether self-compassion plays a mediator role on this relationship. Participants were 203 adults, from both genders, with overweight and obesity ( MBMI = 31.17, standard deviation = 5.43). Women reported higher levels of self-disgust and eating psychopathology and lower levels of self-compassion than men. Path analysis results suggested that the effect of self-disgust on eating psychopathology occurred partially through one’s inability to be self-compassionate. The results highlight the damaging role of self-disgust on eating psychopathology and the importance of developing a more compassionate attitude towards the self to promote healthy eating behaviors.

Use of doping agents and symptoms of eating disorders among male and female patients in drug addiction treatment

Aims

This study investigates the prevalence of use of doping agents and symptoms of eating disorders among patients in drug addiction treatment. The aim is also to look for characteristics of the groups reporting the use of doping agents or symptoms of eating disorders.

Design

A survey including questions on exercise, the use of doping agents and Eating Disorder Inventory-2 was administered in a Norwegian drug addiction facility. The study included 109 patients in residential drug treatment, 30 females and 79 males (ranging from 17 to 50 years old).

Results

–Symptoms of eating disorders were reported by 33 percent of the females and 7.6 percent of the males. Previous use of doping agents (anabolic-androgenic steroids in particular) was reported by 40.5 percent of the men and 20 percent of the women. The results are discussed in light of the theory on emotion regulation, gender and cultural expectations, drug treatment as a liminal phase and similarities to drug addiction.

Conclusions

The symptoms of eating disorders and the use of doping agents are prevalent in this sample of male and female drug addicts in treatment. Drug treatment facilities should be aware of this and take the appropriate actions regarding attention, screening and treatment.

Perception of Peripersonal and Interpersonal Space in Patients with Restrictive-type Anorexia

This study examines whether the perception of peripersonal action-space and interpersonal social-space is modified in patients with restrictive-type anorexia in two experimental conditions using videos. First, participants stopped the video of an approaching stimulus when they felt the distance to be comfortable for interacting with it (first-person perspective). Second, participants stopped the video when an observed individual approaching a stimulus, or being approached by it, was at a comfortable distance (third-person perspective). In the first-person perspective, the results showed an estimation of peripersonal space that did not differ from controls when an object was approaching and an increase in interpersonal space compared with controls when a male or female individual was approaching. In the third-person perspective, both individual-object and individual-individual distances were larger in anorexic patients. These results indicate a specific deficit in adjusting interpersonal distances in both the first-person and third-person perspectives.

An Integrative Bio-Psycho-Social Theory of Anorexia Nervosa

The need for novel approaches to understanding and treating anorexia nervosa (AN) is well recognized. The aim of this paper is to describe an integrative bio-psycho-social theory of maintaining factors in AN. We took a triangulation approach to develop a clinically relevant theory with face validity and internal consistency. We developed theoretical ideas from our clinical practice and reviewed theoretical ideas within the eating disorders and wider bio-psycho-social literature. The synthesis of these ideas and concepts into a clinically meaningful framework is described here. We suggest eight key factors central to understanding the maintenance and treatment resistance of anorexia nervosa: genetic or experiential predisposing factors; dysfunctional feelings processing and regulation systems; excessive vulnerable feelings; 'feared self' beliefs; starvation as a maladaptive physiological feelings regulation mechanism; maladaptive psychological coping modes; maladaptive social behaviour; and unmet physical and psychological core needs. Each of these factors serves to maintain the disorder. The concept of universal physical and psychological core needs can provide an underpinning integrative framework for working with this distinctly physical and psychological disorder. This framework could be used within any treatment model. We suggest that treatments which help address the profound lack of trust, emotional security and self-acceptance in this patient group will in turn address unmet needs and improve well-being. Copyright © 2016 John Wiley & Sons, Ltd.

KEY PRACTITIONER MESSAGE

The concept of unmet physical and psychological needs can be used as an underlying integrative framework for understanding and working with this patient group, alongside any treatment model. A functional understanding of the neuro-biological, physiological and psychological mechanisms involved in anorexia nervosa can help patients reduce self-criticism and shame. Fears about being or becoming fat, greedy, needy, selfish and unacceptable ('Feared Self') drive over-compensatory self-depriving behaviour ('Anorexic Self'). Psychological treatment for anorexia nervosa should emphasize a focus on feelings and fostering experiences of acceptance and trust. Treatment for patients with anorexia nervosa needs to be longer than current clinical practice.

Alexithymia, empathy, emotion identification and social inference in anorexia nervosa: A case-control study

Alexithymia, difficulties in facial emotion recognition, poor socio-relational skills are typical of anorexia nervosa (AN). We assessed patients with AN and healthy controls (HCs) with mixed stimuli: questionnaires (Toronto Alexithymia Scale-TAS, Interpersonal Reactivity Index-IRI), photographs (Facial Emotion Identification Test-FEIT) and dynamic images (The Awareness of Social Inference Test-TASIT). TAS and IRI Personal Distress (PD) were higher in AN than HCs. Few or no differences emerged at the FEIT and TASIT, respectively. Larger effect sizes were found for the TAS results. Despite higher levels of alexithymia, patients with AN seem to properly acknowledge others' emotions while being inhibited in the expression of their own.

New Insights in Anorexia Nervosa

Anorexia nervosa (AN) is classically defined as a condition in which an abnormally low body weight is associated with an intense fear of gaining weight and distorted cognitions regarding weight, shape, and drive for thinness. This article reviews recent evidences from physiology, genetics, epigenetics, and brain imaging which allow to consider AN as an abnormality of reward pathways or an attempt to preserve mental homeostasis. Special emphasis is put on ghrelino-resistance and the importance of orexigenic peptides of the lateral hypothalamus, the gut microbiota and a dysimmune disorder of neuropeptide signaling. Physiological processes, secondary to underlying, and premorbid vulnerability factors-the "pondero-nutritional-feeding basements"- are also discussed.

Habilidades sociais: fator de proteção contra transtornos alimentares em adolescentes

Resumo O objetivo desse estudo foi revisar a literatura a cerca da relação entre transtornos alimentares e habilidades sociais em adolescentes. Pesquisou-se as bases de dados Medline, SciELO e Lilacs, cruzando os descritores “transtornos alimentares”, “anorexia nervosa”, “bulimia nervosa” e “comportamento alimentar”, com os descritores “psicologia social” e “isolamento social”, e com as palavras chave “competência social”, “habilidade social” e “relação interpessoal”. Incluiu-se estudos com adolescentes, nos idiomas português, inglês e espanhol, e publicações realizadas entre os anos de 2007 a 2012. A busca resultou em 63 artigos, sendo incluídos 50 nesta revisão. A maioria dos estudos foi conduzido no Brasil e nos Estados Unidos. Do total, 43 eram artigos originais. Os estudos visavam compreender como o estado emocional poderia influenciar no estabelecimento dos transtornos alimentares, assim como as relações interpessoais e a relação entre os pares. Os artigos também discutiram a influência da mídia e da sociedade neste processo. A partir da análise dos estudos, observou-se que quanto maior o repertório de habilidades sociais dos adolescentes, maior será o fator de proteção contra o desenvolvimento de transtornos alimentares.

Restrictive eating in anorexia nervosa: Examining maintenance and consequences in the natural environment

OBJECTIVE

This study examined negative and positive affect in relation to restrictive eating episodes (i.e., meals/snacks perceived as restrictive) and whether restrictive eating was associated with likelihood of subsequent eating disorder behaviors (i.e., additional restrictive eating, binge eating, vomiting, laxative use, weighing, exercising, meal skipping, drinking fluids to curb appetite, body checking).

METHOD

Women with anorexia nervosa (N = 118) completed a 2-week ecological momentary assessment protocol.

RESULTS

For both restrictive and nonrestrictive eating, negative affect significantly increased from prebehavior to the time of the behavior but remained stable thereafter, while positive affect remained stable from prebehavior to the time of the behavior but decreased significantly thereafter. Across time, negative affect was significantly lower and positive affect was significantly greater in restrictive than nonrestrictive episodes. Engagement in restrictive eating was associated with an increased likelihood of subsequent restrictive eating, laxative use, and body checking, but not other behaviors. Engagement in nonrestrictive eating was associated with a decreased likelihood of subsequent restrictive eating, binge eating, vomiting, laxative use, weighing, meal skipping, drinking fluids to curb appetite, and body checking.

DISCUSSION

Despite similar patterns of affect across eating episodes over time, results suggest affect may be involved in the maintenance of restrictive eating in anorexia nervosa since restrictive episodes were associated with lower negative and greater positive affect across time compared to nonrestrictive episodes. Further, while restrictive episodes increased the likelihood of only three subsequent eating disorder behaviors, nonrestrictive episodes were protective since they decreased likelihood of all but one behavior.

Development and Validation of the Pride in Eating Pathology Scale (PEP-S)

There is a growing body of theoretical and clinical literature highlighting the role of pride in maintaining eating disordered behaviours. Despite its clinical importance, there are no measures to assess feelings of pride associated with eating psychopathology. This study describes the development and validation of the Pride in Eating Pathology Scale (PEP-S), a self-report questionnaire that examines feelings of pride towards eating disordered symptoms (e.g., pride in food restriction, thinness and weight loss). Participants were 390 females, recruited from university and community populations, whose mean age was 26.99 years. Respondents rated pride in eating pathology on a 7-point Likert-scale. Principal Component Analysis indicated that the 60-item scale comprised a four component structure: (1) pride in weight loss, food control and thinness, (2) pride in healthy weight and healthy eating, (3) pride in outperforming others and social recognition and (4) pride in capturing other people's attention due to extreme thinness. These four components explained a total of 65.31% of the variance. The PEP-S demonstrated very good internal reliability (α ranging from 0.88 to 0.98) and very good test-retest reliability over a 3-week time-span (r ranging from 0.81 to 0.93). The PEP-S also showed excellent convergent and discriminant validity. Furthermore, the scale discriminated between women with high and low levels of eating psychopathology. The PEP-S is a psychometrically robust measure of pride in eating pathology. It has the potential to advance theoretical understanding and may also be clinically useful.

KEY PRACTITIONER MESSAGE

The PEP-S is a valid, reliable, quick and easy to administer self-report questionnaire that measures pride related to eating pathology. The PEP-S assesses four clinically relevant dimensions: (1) pride in weight loss, food control and thinness, (2) pride in healthy weight and healthy eating, (3) pride in outperforming others and social recognition and (4) pride in capturing other people's attention due to extreme thinness. The PEP-S has very good internal and test-retest reliability, and very good convergent and discriminant validity. The PEP-S distinguishes between women with higher and lower levels of eating psychopathology. The PEP-S makes an important contribution to understanding pride in eating psychopathology, which is essential from both clinical and theoretical perspectives.

Managing Stigma: Disclosure-Response Communication Patterns in Pro-Anorexic Websites

Pro-anorexic websites are a popular online venue for individuals with anorexia, but recent research suggests that they play a role of "online negative enabling support groups" because they can undermine recovery and encourage negative behaviors by validating pro-anorexic views. By analyzing 22,811 messages from 5,590 conversations from the Pro-Ana Nation online discussion board forum, this study examines communicative mechanisms of online negative enabling support through language analysis of disclosure-response sequences, changes in the language of the initial discloser within an interaction exchange, and the role of responses in eliciting those changes. The findings show that initiating disclosures containing stigma-related emotion words, anorexia-specific content, and sociorelational content are typically met with negatively valenced responses from other members of the pro-anorexic community. Moreover, although the act of revealing stigmatized information has some cathartic effects, disclosers use more, not fewer, stigma-related emotion words when they receive negatively valenced responses. These results provide insight into communicative dynamics and effects of online negative enabling support through validation of the pro-anorexic identity and the dangerous cycle of stigma escalation in disclosure-response exchanges on pro-anorexic online communities.

Emotional Processing, Recognition, Empathy and Evoked Facial Expression in Eating Disorders: An Experimental Study to Map Deficits in Social Cognition

BACKGROUND

Difficulties in social cognition have been identified in eating disorders (EDs), but the exact profile of these abnormalities is unclear. The aim of this study is to examine distinct processes of social-cognition in this patient group, including attentional processing and recognition, empathic reaction and evoked facial expression in response to discrete vignettes of others displaying positive (i.e. happiness) or negative (i.e. sadness and anger) emotions.

METHOD

One hundred and thirty-eight female participants were included in the study: 73 healthy controls (HCs) and 65 individuals with an ED (49 with Anorexia Nervosa and 16 with Bulimia Nervosa). Self-report and behavioural measures were used.

RESULTS

Participants with EDs did not display specific abnormalities in emotional processing, recognition and empathic response to others' basic discrete emotions. However, they had poorer facial expressivity and a tendency to turn away from emotional displays.

CONCLUSION

Treatments focusing on the development of non-verbal emotional communication skills might be of benefit for patients with EDs.

Emotion regulation in disordered eating: Psychometric properties of the Difficulties in Emotion Regulation Scale among Spanish adults and its interrelations with personality and clinical severity

Objective: The aims of the study were to (1) validate the Difficulties in Emotion Regulation Scale (DERS) in a sample of Spanish adults with and without eating disorders, and (2) explore the role of emotion regulation difficulties in eating disorders (ED), including its mediating role in the relation between key personality traits and ED severity.

Methods: One hundred and thirty four patients (121 female, mean age = 29 years) with anorexia nervosa (n = 30), bulimia nervosa (n = 54), binge eating (n = 20), or Other Specified Feeding or Eating Disorders (n = 30) and 74 healthy control participants (51 female, mean age = 21 years) reported on general psychopathology, ED severity, personality traits and difficulties in emotion regulation. Exploratory and confirmatory factor analyses were conducted to examine the psychometrics of the DERS in this Spanish sample (Aim 1). Additionally, to examine the role of emotion regulation difficulties in ED (Aim 2), differences in emotion regulation difficulties across eating disorder subgroups were examined and structural equation modeling was used to explore the interrelations among emotion regulation, personality traits, and eating disorder severity.

Results: Results support the validity and reliability of the DERS within this Spanish adult sample and suggest that this measure has a similar factor structure in this sample as in the original sample. Moreover, emotion regulation difficulties were found to differ as a function of eating disorder subtype and to mediate the relation between two specific personality traits (i.e., high harm avoidance and low self-directedness) and ED severity.

Conclusions: Personality traits of high harm avoidance and low self-directedness may increase vulnerability to ED pathology indirectly, through emotion regulation difficulties.

Experiences of Detention under the Mental Health Act for Adults with Anorexia Nervosa

People with Anorexia Nervosa are often resistant to treatment and can be detained under the Mental Health Act. Detention can be distressing for some client groups; however, there is little research to explore how people with Anorexia Nervosa experience detention and how these experiences impact on recovery. This study utilized a qualitative methodology to develop a model for understanding how people perceive, experience and process detention under the Mental Health Act. Data from 12 participants was analysed using constructivist grounded theory. Four overarching categories conceptualize their experience over time: 'the battle', 'the bubble', 'stepping out of the bubble' and 'the anorexic self'. Within each overarching category are further subordinate categories that represent the nuances of the data. The resultant model is discussed in relation to the literature, whilst recommendations have been made to embed person-centred, recovery practice into inpatient services. Copyright © 2015 John Wiley & Sons, Ltd.

KEY PRACTITIONER MESSAGE

People detained under the mental health act with anorexia nervosa often respond by engaging in a battle with clinicians. This follows by the person withdrawing into a 'bubble' where the individual starts to feel some relief that they are no longer in control of their eating, but this competes with the lack of self and the emerging anorexic self. Clinicians need to be aware that individuals detained may have mixed feelings about their hospital admission.

Emotion generation and regulation in anorexia nervosa: a systematic review and meta-analysis of self-report data

This systematic review sought to examine the generation and regulation of emotion in people with Anorexia Nervosa (AN). Key databases (Medline, Embase, PsychINFO and Web of Science) were searched for peer-reviewed articles published by March 2015 yielding 131 studies relevant to emotion generation and emotion regulation (ER) processes as defined by Gross (1998). Meta-analyses determined pooled group differences between AN and healthy control (HC) groups. More maladaptive schemata were reported by people with AN than HCs, with largest pooled effects for defectiveness/shame (d=2.81), subjugation (d=1.59) and social isolation (d=1.66). Poorer awareness of and clarity over emotion generated and some elevated emotionality (disgust and shame) were reported. A greater use of 'maladaptive' ER strategies was reported by people with AN than HCs, alongside less use of 'adaptive' strategies. Pooled differences of particularly large effect were observed for: experiential avoidance (d=1.00), negative problem-solving style (d=1.06), external/social comparison (d=1.25), submissiveness (d=1.16), attention concentration (worry/rumination; d=1.44) and emotion suppression (d=1.15), particularly to avoid conflict (d=1.54). These data support the notion that emotion regulation difficulties are a factor in AN and support use of associated cognitive-affective models. The implications of these findings for further understanding AN, and developing models and related psychological interventions are discussed.
