Can we fight stigma with science? The effect of aetiological framing on attitudes towards anorexia nervosa and the impact on volitional stigma

The limitations of investigating appetite through circuit manipulations: are we biting off more than we can chew?

Disordered eating can underpin a number of debilitating and prevalent chronic diseases, such as obesity. Broader advances in psychopharmacology and biology have motivated some neuroscientists to address diet-induced obesity through reductionist, pre-clinical eating investigations on the rodent brain. Specifically, chemogenetic and optogenetic methods developed in the 21st century allow neuroscientists to perform in vivo, region-specific/projection-specific/promoter-specific circuit manipulations and immediately assess the impact of these manipulations on rodent feeding. These studies are able to rigorously conclude whether a specific neuronal population regulates feeding behaviour in the hope of eventually developing a mechanistic neuroanatomical map of appetite regulation. However, an artificially stimulated/inhibited rodent neuronal population that changes feeding behaviour does not necessarily represent a pharmacological target for treating eating disorders in humans. Chemogenetic/optogenetic findings must therefore be triangulated with the array of theories that contribute to our understanding of appetite. The objective of this review is to provide a wide-ranging discussion of the limitations of chemogenetic/optogenetic circuit manipulation experiments in rodents that are used to investigate appetite. Stepping into and outside of medical science epistemologies, this paper draws on philosophy of science, nutrition, addiction biology and neurophilosophy to prompt more integrative, transdisciplinary interpretations of chemogenetic/optogenetic appetite data. Through discussing the various technical and epistemological limitations of these data, we provide both an overview of chemogenetics and optogenetics accessible to non-neuroscientist obesity researchers, as well as a resource for neuroscientists to expand the number of lenses through which they interpret their circuit manipulation findings.

University students' understanding and opinions of eating disorders: a qualitative study

BACKGROUND

Eating disorders (EDs) affect 1.25 million people in the UK. Evidence suggests the public display stigma and poor mental health literacy (MHL) towards EDs. There is a high prevalence of EDs in university populations, so it is important to determine the MHL of this at-risk group. Qualitative research exploring the MHL of this population is incomplete.

OBJECTIVE

Explore university students' beliefs and opinions of EDs, their knowledge of symptoms, treatment and help sources and how these are influenced by biological sex.

DESIGN

A qualitative study, using semistructured interviews analysed using inductive thematic analysis.

SETTING

The University of Birmingham.

PARTICIPANTS

Seven female and seven male University of Birmingham students.

RESULTS

Analysis revealed six themes, each with subthemes: ED characteristics, causes, body image, seeking help, stigma and awareness. Students displayed poor awareness towards ED signs and symptoms, causes and help sources. Students were not stigmatising towards EDs, but many perceived them as a female problem and believed society to be stigmatising. Many referenced informal sources of information such as social media and expressed a desire for ED teaching. Sex did not have a significant influence on knowledge or opinions of EDs in this study; however, there were some differences, for example, some males were more likely to see EDs as a weakness and to perceive themselves as having low levels of knowledge.

CONCLUSIONS

University students show broad awareness of EDs; however, knowledge of certain aspects of ED-MHL including help sources and symptom recognition was lacking. Although students were not stigmatising of EDs themselves, many perceived high levels of public stigma. This, alongside poor knowledge, may delay help-seeking. Campaigns educating students and the public about EDs would aid earlier diagnosis, improving long-term outcomes. Further research into awareness and knowledge in other populations would be beneficial.

Effectively Communicating About HIV and Other Health Disparities: Findings From a Literature Review and Future Directions

Despite significant progress in the prevention and treatment of HIV, disparities in rates of infection remain among key groups in the United States, including blacks and African Americans; Hispanics/Latinos; and men who have sex with men (MSM). The U.S. Department of Health and Human Services' initiative, Ending the HIV Epidemic: A Plan for America, calls for addressing HIV-related disparities and reducing stigma and discrimination associated with HIV. The goal of this literature review was to identify approaches for effectively communicating about health disparities across the HIV care continuum. We reviewed the literature to investigate strategies used to communicate health disparities and to identify potential unintended adverse effects resulting from this messaging. Messages about health disparities often target subgroups at higher risk and can be framed in a variety of ways (e.g., social comparison, progress, impact, etiological). Studies have examined the effects of message framing on the risk perceptions, emotional reactions, and behaviors of individuals exposed to the messaging. The evidence points to several potential unintended adverse effects of using social comparison framing and individual responsibility framing to communicate about health disparities, and visual images and exemplars to target messages to higher-risk subgroups. There is not yet a clear evidence-based approach for communicating about health disparities and avoiding potential unintended effects. However, we offer recommendations for communicating about HIV-related disparities based on our findings. Because we found limited literature that addressed our research questions in the context of HIV, we propose a research agenda to build an evidence base for developing effective messages about HIV-related disparities.

Eating disorders "mental health literacy": a scoping review

Background: While it is apparent that much has been learned about "mental health literacy" (MHL) relating to certain mental health problems, such as depression, in recent years, what has been learned about MHL relating to eating disorders (ED-MHL) is unclear.Aims: A scoping review was conducted to inform the current state of knowledge in this field.Methods: A systematic search of relevant literature published between 1997 and 2017 was followed by a narrative synthesis of the findings.Results: The number of eligible studies increased from 32 in 1997-2001 to 98 in 2012-2017 (total = 264). Most studies originated from North America or Europe, recruited individuals with EDs receiving treatment or college students and included both female and male or only female participants. The majority of studies examined MHL relating to anorexia nervosa or bulimia nervosa and examined attitudes which facilitate recognition and appropriate help-seeking and knowledge and beliefs about professional help available.Conclusion: Interest in ED-MHL is increasing and there is now a considerable body of research addressing some aspects of ED-MHL in a range of study populations. Notable gaps in the literature exist, including a paucity of information about ED-MHL relating to EDs other than anorexia nervosa and bulimia nervosa, ED behaviour in males and the use of self-help interventions. We hope the findings will provide an incentive to further research in these and other aspects of ED-MHL.

Eating Disorder Recovery: A Metaethnography

BACKGROUND: Eating disorders seriously affect both physical health and psychosocial functioning. Breaking the confines of an eating disorder requires engagement in a multifaceted recovery process. OBJECTIVE: This article provides a synthesis of 12 qualitative research studies with various eating disordered populations (anorexia nervosa, bulimia nervosa, binge eating disorder, eating disorder not otherwise specified, and other specified feeding and eating disorders) to elucidate the recovery process from the perspective of those who have overcome the disease. METHOD: A metasynthesis of qualitative studies was conducted using Noblit and Hare's metaethnographic methodology. RESULTS: Five overarching themes emerged from the data: (1) the eating disorder as a life jacket, (2) drowning: recognizing consequences, (3) treading the surface: contemplating recovery, (4) swimming: the path toward recovery, and (5) reaching recovery: a sense of freedom. CONCLUSIONS: Eating disorder treatment often entails a cycle of transitions before recovery occurs. Synthesizing the experiences from the perspective of individuals who have overcome an eating disorder presents a unique understanding of the treatment and recovery process.

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.

Feminist approaches to Anorexia Nervosa: a qualitative study of a treatment group

BACKGROUND

Eating disorders (EDs) are now often approached as biopsychosocial problems. But it has been suggested by scholars interested in sociocultural factors that all is not equal within this biospsychosocial framework, with the 'social' aspects of the equation relegated to secondary factors within ED treatment contexts. Although sociocultural influences are well-established as risk factors for EDs, the exploration of whether or how such perspectives are useful in treatment has been little explored. In responding to this context, this article seeks to discuss and evaluate a 10 week closed group intervention based on feminist approaches to EDs at a residential eating disorder clinic in the East of England.

METHODS

The data was collected via one-to-one qualitative interviews and then analysed using thematic discourse analysis.

RESULTS

The participants suggested that the groups were helpful in enabling them to situate their problem within a broader cultural and group context, that they could operate as a form of 'protection' from ideologies regarding femininity, and that a focus on the societal contexts for EDs could potentially reduce feelings of self-blame. At the same time, the research pointed to the complexities of participants considering societal rather than individualised explanations for their problems, whilst it also confronted the implications of ambivalent responses toward feminism.

CONCLUSIONS

Highly visible sociocultural factors in EDs - such as gender - may often be overlooked in ED clinical contexts. Although based on limited data, this research raises questions about the marginalisation of sociocultural factors in treatment, and the benefits and challenges including the latter may involve.

Interventions to reduce the stigma of eating disorders: A systematic review and meta-analysis

Stigma is a problem for individuals with eating disorders (EDs), forming a barrier to disclosure and help-seeking. Interventions to reduce ED stigma may help remove these barriers; however, it is not known which strategies (e.g., explaining etiology to reduce blame, contact with a person with an ED, or educating about ED) are effective in reducing stigma and related outcomes. This review described effectiveness of intervention strategies, and identified gaps in the literature. A search of four databases was performed using the terms (eating disorder* OR bulimi* OR anorexi* OR binge-eating disorder) AND (stigma* OR stereotyp* OR beliefs OR negative attitudes) AND (program OR experiment OR intervention OR education), with additional texts sought through LISTSERVs. Two raters screened papers, extracted data, and assessed quality. Stigma reduction strategies and study characteristics were examined in critical narrative synthesis. Exploratory meta-analysis compared the effects of biological and sociocultural explanations of EDs on attitudinal stigma. Eighteen papers were eligible for narrative synthesis, with four also eligible for inclusion in a meta-analysis. Biological explanations reduced stigma relative to other explanations, including sociocultural explanations in meta-analysis (g = .47, p < .001). Combined education and contact interventions improved stigma relative to control groups or over time. Most studies examined Anorexia Nervosa (AN) stigma and had mostly female, undergraduate participants. Despite apparent effectiveness, research should verify that biological explanations do not cause unintentional harm. Future research should evaluate in vivo contact, directly compare education and contact strategies, and aim to generalize findings across community populations.

How do differential explanations of voice-hearing influence attributions and behavioral intentions towards voice-hearers?

Explanations regarding the etiology of mental health difficulties have been found to affect public attitudes towards those who experience such difficulties. Utilizing a large, randomized parallel-groups design (N=1004), we examined how standardized differential explanations of voice-hearing influence public attitudes, attributions, and behavioral intentions towards voice-hearers. Additionally, we incorporated a behavioral outcome measure to examine whether reported behavioral intentions towards voice-hearers were related to responses towards an individual with a history of voice-hearing. Consistent with attribution theory, mediated pathways between attributions and intentions were identified: broadly, viewing the voice-hearer's behavior as dangerous, within their personal responsibility, and global was associated with more coercive intentions - and these were mediated by feelings of fear, anger, and pity. Reported behavioral intentions demonstrated small-to-moderate associations with our behavioral outcome measure. The findings suggest that explanations regarding the etiology of mental health difficulties that seek to reduce public attributions of dangerousness, personal responsibility, and globality may facilitate more helpful responses towards voice-hearers.

Stigma and eating and weight disorders

Although research has consistently documented the prevalence and negative health implications of weight stigma, little is known about the stigma associated with eating disorders. Given that weight stigma is a risk factor associated with disordered eating, it is important to address stigma across the spectrum of eating and weight disorders. The aim of this review is to systematically review studies in the past 3 years evaluating stigma in the context of obesity and eating disorders (including binge eating disorder, bulimia nervosa, and anorexia nervosa). Physical and psychological health consequences of stigma for individuals with obesity and eating disorders are discussed. Recent studies on weight stigma substantiate the unique influence of stigma on psychological maladjustment, eating pathology, and physiological stress. Furthermore, research documents negative stereotypes and social rejection of individuals with eating disorder subtypes, while attributions to personal responsibility promote blame and further stigmatization of these individuals. Future research should examine the association of stigma related to eating disorders and physical and emotional health correlates, as well as its role in health-care utilization and treatment outcomes. Additional longitudinal studies assessing how weight stigma influences emotional health and eating disorders can help identify adaptive coping strategies and improve clinical care of individuals with obesity and eating disorders.

Educating medical students about anorexia nervosa: a potential method for reducing the volitional stigma associated with the disorder

It is frequently reported that clinicians across a range of professional disciplines experience strong negative reactions toward patients with anorexia nervosa (AN). The present study aimed to develop, evaluate, and compare the effectiveness of two different educational programs, based on an etiological framing model. Participants were medical students (N = 41) from an Australian University, who were randomly assigned to one of three conditions (biogenetic intervention vs. multifactorial intervention vs. control). Outcome attitudinal/stigma data were collected pre- and post-intervention, and at 8 weeks follow-up. Results indicated intervention participations exhibited significantly lower volitional stigma scores compared to the control group, who exhibited no change in attitudes or stigma. Specifically, intervention participants had significantly lower total ED stigma scores, levels of blame, perceptions of AN as a selfish/vain illness, and viewed sufferers as less responsible for their illness at post-intervention. These reductions were maintained at follow-up. Overall, the study provides preliminary evidence that brief targeted interventions can assist in reducing levels of volitional stigma toward AN.
