A systematic review of the 'eating disorder voice' experience

An exploration of the relationship between loneliness, the severity of eating disorder-related symptoms and the experience of the 'anorexic voice'

OBJECTIVES

Many individuals with eating disorders (EDs) report the experience of an 'Anorexic voice' (AV). Negative experiences of loneliness are also often associated with EDs. This study sought to explore the relationship between experiences of loneliness, the frequency of the AV and the impact of this on ED symptom severity.

DESIGN

165 individuals (mean age 27.54 years) who accessed online forums relating to EDs participated in this study. The sample included individuals who have experienced an AV [AV group (N  = 141)] and those who have not [non-AV group (N  = 23)].

METHODS

The study utilised self-report measures via an online questionnaire to explore the predictive validity of loneliness and frequency of the AV on ED symptom severity.

RESULTS

Confirmatory analysis (AV group only) demonstrated the significance of the independent variables individually predicting ED symptom severity. However, a significant interaction was not found between the two primary variables in predicting ED symptom severity, more significantly than the influence of either variable alone. Exploratory analysis considered the differences between the two groups (AV and Non-AV), as well as considering alternate predictors.

CONCLUSIONS

The findings offer insight into possible drivers behind engagement with the AV, as part of ED presentations in the community.

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.

The Nepean Belief Scale (NBS) as a tool to investigate the intensity of beliefs in anorexia nervosa: psychometric properties of the Italian version

BACKGROUND

People with anorexia nervosa (AN) show a peculiar impairment of insight regarding their condition, often manifesting a denial of extreme emaciation and sometimes hiding or underreporting socially undesirable abnormal eating patterns. Sometimes the intensity of the beliefs held by patients with AN reach a delusional intensity.

OBJECTIVES

In this study, the Italian version of the Nepean Belief Scale was applied to a sample of patients diagnosed with AN to investigate the intensity of their beliefs and convictions and its clinical correlates.

METHODS

The Nepean Belief Scale (NBS) was translated and adapted to Italian and applied to a sample of patients diagnosed with AN based on the Structured Clinical Interview for DSM-5 (SCID-5).

RESULTS

The Italian version of the 5-item NBS showed excellent reliability. Convergent validity was proved by negative association with levels of insight measured with the Schedule for the Assessment of Insight in Eating Disorders. Beliefs of delusional intensity were reported by 10% of participants. Those with a greater intensity of beliefs, either overvalued or delusional ideas, were more likely to report poorer general cognitive performances on the Montreal Cognitive Assessment. No association was observed between NBS score and age, body mass index, symptoms of eating disorders, body dissatisfaction, or levels of depression. Fear of weight gain and control seeking were the most often reported themes at the NBS.

CONCLUSIONS

The Italian version of the NBS is a reasonably reliable, valid, and usable tool for the multidimensional assessment of insight in AN. Level of evidence Level III, Evidence obtained from well-designed cohort or case-control analytic studies.

A case series to test the acceptability, feasibility and preliminary efficacy of AVATAR therapy in anorexia nervosa

BACKGROUND

Patients with anorexia nervosa tend to experience an inner "eating disorder" voice. They struggle to recognise and assert their own identity over the illness's identity and relate to it from a powerless and subordinate position. AVATAR therapy was developed to help patients with psychosis to gain greater power and control over distressing voices. The goal of this study was to test the feasibility, acceptability, safety and preliminary efficacy of an adaptation of AVATAR therapy for anorexia nervosa.

METHODS

Twelve adult patients with anorexia nervosa were recruited. Ten completed an assessment session and between five to seven therapy sessions. The assessment session consisted in the creation of an avatar to represent the "eating disorder". This was accomplished by manipulating auditory and visual characteristics through a specialist computer software. During the therapy sessions, patients interacted with the avatar to assert their own desires and will. Patients completed baseline, end of intervention and follow-up (4-week) online questionnaires. A non-concurrent multiple baselines single case experimental design (SCED) was used (A1BA2). Feasibility, acceptability, safety and preliminary efficacy of the intervention were assessed.

RESULTS

The therapy met pre-specified criteria relating to (1) Feasibility: sample recruited within three months; retention rate at the end of the treatment phase = 81.9%; therapy completion rate = 90.1%. (2) Safety: no serious adverse events associated with the intervention. (3) Acceptability: mean ratings = 7.5 (SD = 2.61) out of ten, on a 0-10 scale of acceptability (10 = complete satisfaction). With regards to efficacy, participants reported significantly lower levels of distress associated with the eating disorder voice and higher levels of self-compassion at the end of treatment. No other significant changes were observed in frequency of the eating disorder voice, voice's characteristics, such as omnipotence and malevolence, eating disorder symptoms and symptoms of anxiety, depression and stress. Patients' feedback indicated that the therapy had helped with their ability to stand up to the illness, make positive changes around eating, and increase their motivation to recover and self-compassion.

CONCLUSION

AVATAR therapy for anorexia nervosa is feasible, acceptable and safe for patients. Larger studies are needed to test clinical efficacy.

TRIAL REGISTRATION

The study was pre-registered on the clinicaltrials.gov registry (https://clinicaltrials.gov/ct2/show/NCT04778423).

Living and leaving a life of coercion: a qualitative interview study of patients with anorexia nervosa and multiple involuntary treatment events

BACKGROUND

A small but significant group of patients with anorexia nervosa (AN) undergo multiple involuntary treatment (IT) events. To enhance our understanding of IT and potentially inform treatment, we explored experiences and perspectives on IT of these patients.

METHODS

We designed a qualitative semi-structured interview study and used reflexive thematic analysis. Participants were at least 18 years of age, had multiple past IT events (≥ 5) related to AN over a period of at least one month of which the last IT event happened within the preceding five years. Participants had no current IT, intellectual disability, acute psychosis, or severe developmental disorder. We adopted an inductive approach and constructed meaning-based themes.

RESULTS

We interviewed seven participants. The data portrayed a process of living and leaving a life of coercion with a timeline covering three broad themes: living with internal coercion, coercive treatment, and leaving coercion; and five subthemes: helping an internal battle, augmenting suffering, feeling trapped, a lasting imprint, and changing perspectives. We highlighted that patients with AN and multiple IT events usually experienced internal coercion from the AN prior to external coercion from the health care system. IT evoked significant negative affect when experienced, and often left an adverse imprint. Moreover, IT could help an internal battle against AN and perspectives on IT could change over time.

CONCLUSIONS

Our study suggests that feeling internally coerced by AN itself sets the stage for IT. Clinicians should be conscious of the potential iatrogenic effects of IT, and reserve IT for potentially life-threatening situations.

A proof-of-concept study for the use of a computerised avatar to embody the eating disorder voice in anorexia nervosa

PURPOSE

This study assessed (1) the experience of the eating disorder voice in people with anorexia nervosa or in remission, and (2) the feasibility of creating and interacting with a computerised representation (i.e., avatar) of this voice.

METHODS

Twenty-one individuals with anorexia nervosa and 18 individuals who were in remission participated in the study. They reported on the characteristics of their eating disorder voice and created a personalised avatar (a visual and auditory representation of the eating disorder voice), using a computerised software. Participants assessed closeness of match between the voice and the avatar, perceived distress and acceptability of re-exposure to the avatar.

RESULTS

Patients felt less powerful than their eating disorder voice and unable to disregard the voice's commands. The experience of the voice was associated with negative, as well as some positive emotions, reflecting the prototypical ambivalence towards the illness. Individuals in remission had an opposite pattern of responses. They attributed only negative emotions to the voice, felt more powerful than the voice, and able to disregard its commands. Overall participants reported that there was a good match between the voice and the sound of the avatar. Patients expressed willingness to repeat exposure to the avatar.

CONCLUSION

Individuals with anorexia can create personalised digital avatars representing the eating disorder voice and are willing to engage therapeutically with the avatar. The next step is to test the feasibility of repeated exposure to the avatar to address the power and distress associated with the eating disorder voice.

Emotion dysregulation and eating disorder outcome: Prediction, change and contribution of self-image

OBJECTIVES

Eating disorders (EDs) are severe disorders with unsatisfactory outcome. Emotion dysregulation and self-image are suggested maintenance factors; this study examined emotion dysregulation as potential predictor and/or mechanism of change in relation to ED outcome, and associations between change in emotion dysregulation and self-image in relation to outcome.

DESIGN

Registry data from initial and 1-year follow-up assessments for 307 patients with a wide range of EDs in specialized ED treatment were used.

METHODS

Initial and change (∆) in emotion dysregulation were examined as predictors of 1-year outcome. Direct and indirect associations between ∆emotion dysregulation and ∆self-image as either independent variable or mediator in relation to ∆ED psychopathology as dependent were also examined.

RESULTS

Higher initial emotion dysregulation was weakly associated with higher follow-up ED psychopathology, but not remission, while relative increase in emotion dysregulation was associated with both higher follow-up psychopathology and increased risk of still having a diagnosis. Change in emotion dysregulation primarily had an indirect effect (through change in self-image), while change in self-image had a direct effect, on change in ED psychopathology improvement (such that improvement in one was associated with improvement in the other).

CONCLUSIONS

Results identify emotion dysregulation as a potential mechanism of change in relation to ED outcome. However, this association was mainly mediated by change in self-image. Results indicate that, in order to improve emotion regulation as a means to reduce ED psychopathology, improving self-image is essential.

Eating Disorders and Psychosis as Intertwined Dimensions of Disembodiment: A Narrative Review

Although psychosis is not one of the most commonly recognized psychiatric comorbidities of Eating Disorders (ED), there is an increasing empirical evidence of associations between these psychopathological conditions. Indeed, ED as well as early manifestations of schizophrenic psychosis emerge during developmental years and might present some affinities in the presentation at onset. For example, adolescents with anorexia nervosa (AN) may report psychotic-like eating-related symptoms such as delusional-like body image distortions and/or "anorexic voice". Conversely, early expressions of schizophrenia spectrum vulnerability might involve altered bodily experiences, delusional ideation on food and eating as well as pseudo-anorectic behaviors. From a phenomenological perspective, this partial symptomatic overlap may lie on common features of disturbed corporeality in terms of disembodiment, although these alterations of embodiment are presumably rooted in distinct pathogenetic pathways (e.g., primary childhood ontogenetic pathway in schizophrenia vs. a secondary adolescent ontogenetic pathway in AN). A clinical-phenomenological attitude could be important not only to better discern potential overlaps and affinities between the two conditions, but also to better conceptualize and treat those background alterations of the embodied self. In particular, a phenomenological exploration of the experiential side of eating-related behaviors could be a decisive step to support early differential diagnosis and treatment appropriateness.

Examining dietary self-talk content and context for discretionary snacking behaviour: a qualitative interview study

Background: Consuming discretionary snack foods high in calories, salt, sugar or fat in between regular meals can have a negative impact on weight management and health. Despite the intention to refrain from discretionary snacking, individuals often report feeling tempted by snack foods. A cognitive process to resolve food choice related tension may be dietary self-talk which is one’s inner speech around dietary choice. This study aimed to understand the content and context of dietary self-talk before consuming discretionary snack foods.

Methods: Qualitative semi-structured interviews based on Think-Aloud methods were conducted remotely. Participants answered open-ended questions and were presented with a list of 37 dietary self-talk items. Interview transcripts were analyzed thematically.

Results: Interviews (n = 18, age: 19–54 years, 9 men, 9 women) confirmed the frequent use of dietary self-talk with all 37 content items endorsed. Reported use was highest for the self-talk items: ‘It is a special occasion’; ‘I did physical activity/exercise today’; and ‘I am hungry’. Three new items were developed, eight items were refined. Identified key contextual themes were: ‘reward’, ‘social’, ‘convenience’, ‘automaticity’, and ‘hunger’.

Conclusions: This study lists 40 reasons people use to allow themselves to consume discretionary snack foods and identifies contextual factors of dietary-self talk. All participants reported using dietary self-talk, with variation in content, frequency and degree of automaticity. Recognising and changing dietary self-talk may be a promising intervention target for changing discretionary snacking behaviour.

Recognising and managing eating disorders in the emergency department

Compared with other mental health conditions or psychiatric presentations, such as self-harm, which may be seen in emergency departments, eating disorders can seem relatively rare. However, they have the highest mortality across the spectrum of mental health, with high rates of medical complications and risk, ranging from hypoglycaemia and electrolyte disturbances to cardiac abnormalities. People with eating disorders may not disclose their diagnosis when they see healthcare professionals. This can be due to denial of the condition itself, a wish to avoid treatment for a condition which may be valued, or because of the stigma attached to mental health. As a result their diagnosis can be easily missed by healthcare professionals and thus the prevalence is underappreciated. This article presents eating disorders to emergency and acute medicine practitioners from a new perspective using the combined emergency, psychiatric, nutrition and psychology lens. It focuses on the most serious acute pathology which can develop from the more common presentations; highlights indicators of hidden disease; discusses screening; suggests key acute management considerations and explores the challenge of mental capacity in a group of high-risk patients who, with the right treatment, can make a good recovery.

Pharmacotherapeutic strategies for the treatment of anorexia nervosa - too much for one drug?

INTRODUCTION

Anorexia nervosa is a severe psychiatric illness and no medication has been approved for its treatment. This lack of biological treatments requires the development of new directions for pharmacological research.

AREAS COVERED

There is modest but emerging evidence that dopamine D2 and serotonin 1A and 2A receptor agonistic and antagonist medication might be beneficial for weight gain, although the underlying mechanisms are uncertain. Improving quality of life including treating comorbid conditions is an additional important outcome measure, but this has not been well researched. Biological and psychological risk factors together with neurobiological alterations during the illness maintain the disorder 's pathophysiology. Neuroscience research can be used to understand those interactions and advance the research agenda. The authors discuss the above as well as give perspectives on future research.

EXPERT OPINION

If a multidisciplinary approach that includes evidence-based psychotherapy shows unsatisfactory success in weight normalization and cognitive-emotional recovery, then more experimental treatments that are safe and have indicated treatment effectiveness should be tried to augment treatment. Identification and treatment of comorbid conditions to improve quality of life of the patient should also be part of the treatment regimen, even if the effect on weight gain is uncertain.

"Now It's Just Old Habits and Misery"-Understanding the Impact of the Covid-19 Pandemic on People With Current or Life-Time Eating Disorders: A Qualitative Study

Background: Many aspects of the Covid-19 pandemic may make living with or recovery from an eating disorder (ED) particularly challenging. Understanding the processes which underlie the psychological and behavioral responses of people with EDs during this time are key to ensure tailored support in these unprecedented circumstances. Methods: People with lifetime EDs (n = 32) were recruited through social media from May to June 2020 during a period of strict infection control measures in the United Kingdom (i.e., "lockdown," "social distancing"). They completed open-ended questions in an online anonymous questionnaire that invited them to reflect on how various aspects of their lives have been affected by the Covid-19 pandemic, including ED symptoms and coping strategies. Responses were analyzed using thematic analysis. Results: Most respondents reported that their ED worsened or resurfaced. Isolation, low mood, anxiety, lack of structure, disruption to routines, and media/social media messages around weight and exercise seemed to contribute to this. There was a clear sense that individuals struggled with which aspects of psychological distress to prioritize, i.e., mood vs. ED cognitions and behaviors, particularly as attempts to cope with one often exacerbated the other. Nonetheless, some participants reported "silver linings" of the pandemic. Conclusions: In this self-selected sample, deterioration or recurrence of ED symptoms were the norm. This has implications for the provision of treatment and care for people with EDs both in the immediate short-term and in potential future waves of the pandemic, with a significant surge of new and re-referrals expected.
