Characteristics, correlates of burden and support service use of a help-seeking carers of loved ones with an eating disorder.

OBJECTIVE: Carers, vital in the care of individuals with an eating disorder (ED), experience substantial caregiving burden and unmet needs. This study aims to identify factors which contribute to the burden experienced by carers of a loved one with an ED and their support service usage. METHOD: Carers (N = 245) completed an online questionnaire assessing demographic, carer-specific, individual and ED factors. Multivariate relationships with caregiving burden were examined using forwards elimination to produce a parsimonious model of carer burden. RESULTS: The final model, consisting of caregiving factors (e.g., relationship type, skills), carer mental health) and loved one wellbeing (i.e., purging symptoms, depression/self-harm/suicidality) explained a large proportion (62%) of the variance in carers' burden. Carer mental health, caregiving skills and relationship type (e.g., parent, spouse, sibling) were key predictors of carers' burden. Nearly a third of carers had not used any carer support services, yet most carers expressed an interest in such services. CONCLUSION: Caregiving burden is determined by experiences and skills of the carer as well as the person they are caring for. Carer support services should continue to address the general wellbeing of carers and caregiver skills. Research into the barriers to carer support uptake is needed.

Skills-based online self-help program for carers of people with an eating disorder (SupportED): A case series evaluation.

OBJECTIVE: To investigate the acceptability, feasibility, and preliminary effectiveness of "SupportED," a novel, online, self-paced skills-based program for carers/support people of those with lived and/or living experience of an eating disorder (ED). METHOD: Carers of a loved one with an ED were invited to undertake a five-module skills-based (one core module, four optional modules) online program at their own pace. Modules cover general information about EDs, communication, practical skills, treatment engagement, and recovery. Participants completed demographics and were assessed using EDSIS, CASK, and DASS-21 for caregiver burden, skills, and distress, respectively, at program completion and 3-month follow-up. Feedback on the program and modules was also collected. RESULTS: Most carers (65%; 82/126) completed the core module of the program, which is on par with other online learning programs. Nearly half of program completers responded to the 3-month follow-up (n = 39). On average, carers rated the program as relevant and useful and found the information validating and easy to understand, albeit a few carers found the program time-consuming and technically challenging. Intent-to-treat (ITT) linear mixed models demonstrated the preliminary effectiveness of the program for improving carer burden and skills, although the change in carer distress was non-significant. CONCLUSIONS: Results of this case series evaluation suggest SupportED is an acceptable and feasible program for carers and may improve burden and support skill development. Although the online, self-paced format was highly rated, small improvements to improve acceptability were suggested. Reasons for a lack of impact on carer distress are discussed. PUBLIC SIGNIFICANCE: This article describes a case series evaluation of "SupportED," an online skills-based support program for families, carers, and supporters of people with lived experience of an eating disorder. This is the first online carer support program that is designed to be inclusive of all carer types (e.g., partners, siblings) for all eating disorder presentations. Findings suggest the program's suitability and helpfulness for reducing carers' load and bolstering skills and knowledge.

My Diet Study: protocol for a two-part observational, longitudinal, psycho-biological study of dieting in Australian youth.

Introduction: Self-directed dieting (i.e., unsupervised) is very common among adolescents and young adults but has had almost no direct research. This paper describes the protocol for the My Diet Study, a two-arm observational investigation of the natural progression of dieting among young people over a period of 6-months. The study aims to examine the links between self-directed dieting, general physiological and psychological metrics of wellbeing (e.g., depressive symptoms) and biomarkers of gut-brain axis functions (e.g., microbiome and hormones) that are predicted to influence diet adherence through appetite, mood and metabolism regulation. Methods: Young people aged 16-25, intending to start a diet will be invited to participate in this observational study. For Part 1 (psychological arm), participants will be asked to complete a set of questionnaires and diaries at the beginning of every month for 6 months, to assess overall mental (e.g., psychological distress, disordered eating) and physical (e.g., weight) health, perceived diet success, food intake and gastrointestinal movements. For Part 2 (biological arm), a subsample of 50 participants will be asked to provide feces, blood and saliva for bio-sampling each month for the first 3-months of their participation in Part 1. Discussion: The My Diet Study will be the first longitudinal, observational study of dieting in young people combining in-depth psychological and biological data. It is anticipated that the findings will yield psychological & biological information about the impacts and effectiveness of self-directed dieting in young people, inform a framework for advice on safety in dieting among young people and help to establish the potential for biomarkers for risk management and improvement of diet-based lifestyle interventions.

A randomised controlled trial of clinician supported vs self-help delivery of online cognitive behaviour therapy for Bulimia Nervosa.

High dropout rates and poor adherence associated with digital interventions have prompted research into modifications of these treatments to improve engagement and completion rates. This trial aimed to investigate the added benefit of clinician support when paired alongside a ten-session, online cognitive behaviour therapy (CBT) self-help intervention for bulimia nervosa (BN). As part of a three-arm, phase II randomised controlled trial, 114 participants (16 years or over) with full or subthreshold BN were randomly assigned to complete the intervention in a self-help mode (with administrative researcher contact; n = 38), with adjunct clinician support (weekly 30-minute videoconferencing sessions; n = 37), or a no-treatment waitlist control (WLC; n = 39). Baseline to post-treatment (12-weeks) decreases in objective binge episode frequency were significantly greater for clinician-supported participants as compared to WLC, but not for self-help when compared to WLC. However, due to continued improvements for self-help across follow-up (24-weeks), both arms outperformed WLC when analysed as an overall rate of change across three timepoints. Clinician-supported participants outperformed self-help in regards to laxative use and dietary restraint. Our results demonstrate that good clinical outcomes can be achieved with a relatively brief online CBT-based program even in the absence of structured clinical support, indicating a possible overreliance upon clinician support as a primary adherence-facilitating mechanism.

The acceptability, feasibility, and preliminary efficacy of a supported online self-help treatment program for binge-eating disorder.

Introduction: Studies in transdiagnostic eating disorder (ED) samples suggest supported online self-help programs (eTherapies) are effective and may improve access to treatment; however, their evaluation in those with binge-eating disorder (BED) is limited. Given BED's high prevalence and low levels of treatment uptake, further eTherapy evaluation is needed to broaden access to effective, evidence-based treatment options. The aim of this study was to investigate the acceptability, feasibility, and preliminary efficacy of a supported eTherapy for those with BED or subthreshold BED, and to examine symptom change across the duration of therapy. Method: Nineteen women with BED completed a supported, 10-session Cognitive Behavioural Therapy-based eTherapy in an uncontrolled, pre-post, and 3 months follow up intervention study. Key outcomes were assessed by the Eating Disorder Examination Questionnaire (EDE-Q): objective binge episode (OBE) frequency and ED psychopathology. Feasibility was evaluated via program adherence and dropout, whilst acceptability was assessed through participant feedback post-treatment. Weekly symptom change (ED psychopathology) during treatment was assessed by the Eating Disorder Examination - Questionnaire Short (EDE-QS). Results: Generalised estimating equations showed statistically and clinically significant reductions in OBEs and ED psychopathology (large effects) post-treatment, with these decreases maintained at follow up. Across weekly assessment, a marked slowing in the rate of change in ED psychopathology was observed after four sessions of the program. Program feasibility was high (i.e., 84% of content completed), as was program acceptability (i.e., 93% of participants expressed high levels of satisfaction). Discussion: These results support the acceptability, feasibility, and preliminary efficacy of a supported eTherapy program for those with BED and suggest the variability of symptom change across the duration of therapy. Future research should further investigate findings in an adequately powered randomised controlled trial.

Using health administrative data to model associations and predict hospital admissions and length of stay for people with eating disorders.

BACKGROUND: Eating disorders are serious mental illnesses requiring a whole of health approach. Routinely collected health administrative data has clinical utility in describing associations and predicting health outcome measures. This study aims to develop models to assess the clinical utility of health administrative data in adult eating disorder emergency presentations and length of stay. METHODS: Retrospective cohort study on health administrative data in adults with eating disorders from 2014 to 2020 in Sydney Local Health District. Emergency and admitted patient data were collected with all clinically important variables available. Multivariable regression models were analysed to explore associations and to predict admissions and length of stay. RESULTS: Emergency department modelling describes some clinically important associations such as decreased odds of admission for patients with Bulimia Nervosa compared to Anorexia Nervosa (Odds Ratio [OR] 0.31, 95% Confidence Interval [95%CI] 0.10 to 0.95; p = 0.04). Admitted data included more predictors and therefore further significant associations including an average of 0.96 days increase in length of stay for each additional count of diagnosis/comorbidities (95% Confidence Interval [95% CI] 0.37 to 1.55; p = 0.001) with a valid prediction model (R2 = 0.56). CONCLUSIONS: Health administrative data has clinical utility in adult eating disorders with valid exploratory and predictive models describing associations and predicting admissions and length of stay. Utilising health administrative data this way is an efficient process for assessing impacts of multiple factors on patient care and predicting health care outcomes.

Eating disorder outcomes: findings from a rapid review of over a decade of research.

BACKGROUND: Eating disorders (ED), especially Anorexia Nervosa (AN), are internationally reported to have amongst the highest mortality and suicide rates in mental health. With limited evidence for current pharmacological and/or psychological treatments, there is a grave responsibility within health research to better understand outcomes for people with a lived experience of ED, factors and interventions that may reduce the detrimental impact of illness and to optimise recovery. This paper aims to synthesise the literature on outcomes for people with ED, including rates of remission, recovery and relapse, diagnostic crossover, and mortality. METHODS: This paper forms part of a Rapid Review series scoping the evidence for the field of ED, conducted to inform the Australian National Eating Disorders Research and Translation Strategy 2021-2031, funded and released by the Australian Government. ScienceDirect, PubMed and Ovid/MEDLINE were searched for studies published between 2009 and 2022 in English. High-level evidence such as meta-analyses, large population studies and Randomised Controlled Trials were prioritised through purposive sampling. Data from selected studies relating to outcomes for people with ED were synthesised and are disseminated in the current review. RESULTS: Of the over 1320 studies included in the Rapid Review, the proportion of articles focused on outcomes in ED was relatively small, under 9%. Most evidence was focused on the diagnostic categories of AN, Bulimia Nervosa and Binge Eating Disorder, with limited outcome studies in other ED diagnostic groups. Factors such as age at presentation, gender, quality of life, the presence of co-occurring psychiatric and/or medical conditions, engagement in treatment and access to relapse prevention programs were associated with outcomes across diagnoses, including mortality rates. CONCLUSION: Results are difficult to interpret due to inconsistent study definitions of remission, recovery and relapse, lack of longer-term follow-up and the potential for diagnostic crossover. Overall, there is evidence of low rates of remission and high risk of mortality, despite evidence-based treatments, especially for AN. It is strongly recommended that research in long-term outcomes, and the factors that influence better outcomes, using more consistent variables and methodologies, is prioritised for people with ED.

Eating disorders are complex psychiatric conditions that can seriously impact a person's physical health. Whilst they are consistently associated with high mortality rates and significant psychosocial difficulties, lack of agreement on definitions of recovery, remission and relapse, as well as variations in methodology used to assess for standardised mortality and disability burden, means clear outcomes can be difficult to report. The current review is part of a larger Rapid Review series conducted to inform the development of Australia's National Eating Disorders Research and Translation Strategy 2021­2031. A Rapid Review is designed to comprehensively summarise a body of literature in a short timeframe to guide policymaking and address urgent health concerns. This Rapid Review synthesises the current evidence-base for outcomes for people with eating disorders and identifies gaps in research and treatment to guide decision making and future clinical research. A critical overview of the scientific literature relating to outcomes in Western healthcare systems that may inform health policy and research in an Australian context is provided in this paper. This includes remission, recovery and relapse rates, diagnostic cross-over, the impact of relapse prevention programs, factors associated with outcomes, and findings related to mortality.

Appraisal of the costs, health effects, and cost-effectiveness of screening, prevention, treatment and policy-indicated evidence-based interventions for eating disorders: a systematic review protocol.

BACKGROUND: Having reliable information to make decisions about the allocation of healthcare resources is needed to improve well-being and quality-of-life of individuals with eating disorders (EDs). EDs are a main concern for healthcare administrators globally, particularly due to the severity of health effects, urgent and complex healthcare needs, and relatively high and long-term healthcare costs. A rigorous assessment of up-to-date health economic evidence on interventions for EDs is essential for informing decision-making in this area. To date, health economic reviews on this topic lack a comprehensive assessment of the underlying clinical utility, type and amount of resources used, and methodological quality of included economic evaluations. The current review aims to (1) detail the type of costs (direct and indirect), costing approaches, health effects, and cost-effectiveness of interventions for EDs; (2) assess the nature and quality of available evidence to provide meaningful insights into the health economics associated with EDs. METHODS: All interventions for screening, prevention, treatment, and policy-based approaches for all Diagnostic and Statistics Manual (DSM-IV and DSM-5) listed EDs among children, adolescents, and adults will be included. A range of study designs will be considered, including randomised controlled trials, panel studies, cohort studies, and quasi-experimental trials. Economic evaluations will consider key outcomes, including type of resources used (time and valued in a currency), costs (direct and indirect), costing approach, health effects (clinical and quality-of-life), cost-effectiveness, economic summaries used, and reporting and quality assessments. Fifteen general academic and field-specific (psychology and economics) databases will be searched using subject headings and keywords that consolidate costs, health effects, cost-effectiveness and EDs. Quality of included clinical studies will be assessed using risk-of-bias tools. Reporting and quality of the economic studies will be assessed using the widely accepted Consolidated Health Economic Evaluation Reporting Standards and Quality of Health Economic Studies frameworks, with findings of the review presented in tables and narratively. DISCUSSION: Results emanating from this systematic review are expected to highlight gaps in healthcare interventions/policy-focused approaches, under-estimates of the economic costs and disease-burden, potential under-utilisation of ED-related resources, and a pressing need for more complete health economic evaluations.

Prevention and early intervention in eating disorders: findings from a rapid review.

BACKGROUND: Eating disorders (EDs) are complex psychological disorders, with low rates of detection and early intervention. They can lead to significant mental and physical health complications, especially if intervention is delayed. Given high rates of morbidity and mortality, low treatment uptake, and significant rates of relapse, it is important to examine prevention, early intervention, and early recognition initiatives. The aim of this review is to identify and evaluate literature on preventative and early intervention programs in EDs. METHODS: This paper is one of a series of Rapid Reviews, designed to inform the Australian National Eating Disorders Research and Translation Strategy 2021-2031, funded, and released by the Australian Government. To provide a current and rigorous review, peer-reviewed articles between 2009 and 2021 published in English were searched across three databases: ScienceDirect, PubMed and Ovid/Medline. Priority was given to high-level evidence including meta-analyses, systematic reviews, Randomised Control Trials, and large population studies. Findings from selected studies pertaining to prevention and early intervention in EDs were evaluated and are presented in this review. RESULTS: In total, 130 studies were identified in the current review, 72% relating to prevention and 28% to early intervention. Most programs were theory-driven and targeted one or more ED risk factors such as thin-ideal internalisation and/or body dissatisfaction. There is reasonable evidence to support prevention programs reducing risk factors, particularly as part of school or university-based programs, with established feasibility and relatively high acceptance among students. There is increasing evidence around the use of technology (to increase dissemination potential) and for use of mindfulness approaches (targeting emotional resilience). Few longitudinal studies assessing incident cases following participation in a prevention program exist. CONCLUSIONS: Although several prevention and early intervention programs have been shown to significantly reduce risk factors, promote symptom recognition, and encourage help-seeking behaviour, most of these studies have been conducted in older adolescent and university aged students, past the age of peak ED onset. One of the most targeted risk factors, body dissatisfaction, is found in girls as young as 6 years old, indicating a need for further research implementing prevention initiatives at younger ages. Follow-up research is limited; thus, the long-term efficacy and effectiveness of studied programs is unknown. Greater attention should be paid to the implementation of prevention and early intervention programs in identified high-risk cohorts or diverse groups, where a more targeted approach may be necessary.

Models of care for eating disorders: findings from a rapid review.

BACKGROUND: Delayed diagnosis, gaps in services and subsequent delays in specialist care and treatment lead to poorer health outcomes for individuals with eating disorders (EDs) and drive significant government healthcare expenditure. Given the significant disease burden associated with EDs, it is imperative that current implementation research is summarised to identify gaps in care and enable refinement for optimal patient outcomes. This review aimed to provide an updated synthesis on models of care for EDs in developed healthcare systems. METHODS: This paper was conducted as part of a series of Rapid Reviews (RRs) to be published in a special series in the Journal of Eating Disorders. To provide a current and rigorous review, peer-reviewed articles published in the English language between 2009 and 2021 across three databases (ScienceDirect, PubMed and Ovid/Medline) were searched, with priority given to higher level evidence (e.g., meta-analyses, large population studies, Randomised Control Trials (RCTs)). The current review synthesises data from included studies investigating models of care for people with EDs. RESULTS: Sixty-three studies (4.5% of the original RR) were identified, which included several diagnostic populations, the most common being Anorexia Nervosa (AN) (30.51%). Across EDs, specialist care was found to improve patient outcomes, with many patients effectively being treated in outpatient or day programs with multi-disciplinary teams, without the need for lengthy inpatient hospitalisation. Few studies investigated the interaction of different ED services (e.g., inpatient, community services, primary care), however stepped care models emerged as a promising approach to integrate ED services in a targeted and cost-effective way. Issues surrounding low treatment uptake, underdiagnosis, long waiting lists and limited hospital beds were also evident across services. CONCLUSION: Findings suggested further research into alternatives to traditional inpatient care is needed, with partial and shorter 'hospitalisations' emerging as promising avenues. Additionally, to tackle ongoing resource issues and ensure timely detection and treatment of EDs, further research into novel alternatives, such as active waiting lists or a greater role for primary care clinicians is needed. This paper is part of a larger Rapid Review series carried out to guide Australia's National Eating Disorders Research and Translation Strategy 2021-2031. Rapid reviews aim to thoroughly summarise an area of research over a short time period, typically to help with policymaking in this area. This Rapid Review summarises the evidence relating to how we care for people with eating disorders in Western healthcare systems. Topics covered include inpatient/hospital care, residential care, day programs, outpatient/community care, and referral pathways. Findings suggested specialist eating disorder services may enhance detection, referral, and patient care. Stepped care models presented as a cost-effective approach which may help with linkage between different eating disorder services. There was a trend towards shorter hospital stays and approaches which allow for greater connection with the community, such as day programs. Evidence was also found of treatment delays, due to system issues (long waiting lists, lack of accurate assessment and diagnosis) and patient-related barriers (stigma, recognition). Upskilling and involving primary care clinicians in diagnosis and referral as part of a stepped care model may help to address some of these concerns. Further efforts to improve mental health literacy and de-stigmatise help-seeking for eating disorders are needed.

The efficacy of family treatments for adolescent anorexia nervosa in specialist versus non-specialist settings: protocol for a systematic review and meta-analysis.

BACKGROUND: Anorexia nervosa (AN) is often diagnosed in adolescence, and most evidence-based treatments for AN in young people involve the family. Family therapies for AN are intensive, outpatient treatments that utilise the parents as the primary resource in the young person's recovery. Research regarding family treatment for AN is often conducted in specialist settings-with relatively little data reporting the translation of this specialised treatment into real-world, non-specialist settings. This systematic review and meta-analysis aims to determine the efficacy of family treatments for adolescents with AN in specialist settings versus non-specialist settings. METHODS: This systematic review and meta-analysis will be conducted according to the preferred reporting items for systematic reviews and meta-analyses guidelines. Retrospective cohort studies, pilot studies, case series, randomised controlled trials and qualitative investigations that present original data and investigated the efficacy of family treatments for adolescents with AN in either a specialist or non-specialist setting will be included in the review. Data will be extracted by two reviewers and study quality will be assessed. The primary outcome, change in weight, will be used to determine via meta-analysis and, depending on study heterogeneity, subgroup analysis or meta-regression whether there is a statistically significant subgroup difference between specialist and non-specialist treatment settings. The review will also consider changes in eating disorder symptomology and related constructs. DISCUSSION: Results from this review will help determine if there is a difference in the efficacy of family treatments for adolescent AN in specialist versus non-specialist treatment settings, primarily in relation to weight recovery. This, in turn, will inform the translation of evidence-based interventions that are generally studied and implemented within specialist centres into the non-specialist health care system.

Evaluating the feasibility and potential efficacy of a brief eTherapy for binge-eating disorder: A pilot study.

OBJECTIVE: For those with binge-eating disorder (BED), access to evidence-based, face-to-face treatment is often constrained by clinician availability and high treatment costs. Emerging evidence suggests online therapy (eTherapy) may navigate these barriers and reduce binge-eating symptomatology; however, less evaluation has been done in those with BED, particularly with briefer programs targeting early change. This study investigated the feasibility and potential efficacy of a brief, supported eTherapy in those with BED or subthreshold BED. METHOD: Participants were 19 women with BED who completed a four-session eTherapy. This was a single-arm, pre-post intervention study, with participants completing weekly content and attending telehealth sessions. Key outcomes were assessed by the Eating Disorder Examination Questionnaire-Short (EDE-QS): objective binge episode days, loss of control over eating days, and eating disorder (ED) psychopathology via a total EDE-QS score. RESULTS: Generalized and linear mixed models showed significantly reduced loss of control over eating days and ED psychopathology. Program feasibility was high, with strong program adherence and a below average attrition rate. DISCUSSION: Pilot results support the feasibility and potential efficacy of a brief, behavioral-focused eTherapy program in reducing ED pathology in those with BED. Future research should further investigate findings in an adequately powered randomized controlled trial. PUBLIC SIGNIFICANCE: This study suggests that a brief, behavioral-focused online therapy, guided by non-expert clinicians, can be successfully administered to those with binge-eating disorder (BED) and may be efficacious at reducing eating disorder and other related symptomatology. Brief eTherapies that are effective, accessible, and rapidly available may facilitate earlier intervention in illness and improve treatment outcomes for individuals who experience this common and distressing disorder.

Informing the development of Australia's National Eating Disorders Research and Translation Strategy: a rapid review methodology.

BACKGROUND: Eating disorders (EDs) are highly complex mental illnesses associated with significant medical complications. There are currently knowledge gaps in research relating to the epidemiology, aetiology, treatment, burden, and outcomes of eating disorders. To clearly identify and begin addressing the major deficits in the scientific, medical, and clinical understanding of these mental illnesses, the Australian Government Department of Health in 2019 funded the InsideOut Institute (IOI) to develop the Australian Eating Disorder Research and Translation Strategy, the primary aim of which was to identify priorities and targets for building research capacity and outputs. A series of rapid reviews (RR) were conducted to map the current state of knowledge, identify evidence gaps, and inform development of the national research strategy. Published peer-reviewed literature on DSM-5 listed EDs, across eight knowledge domains was reviewed: (1) population, prevalence, disease burden, Quality of Life in Western developed countries; (2) risk factors; (3) co-occurring conditions and medical complications; (4) screening and diagnosis; (5) prevention and early intervention; (6) psychotherapies and relapse prevention; (7) models of care; (8) pharmacotherapies, alternative and adjunctive therapies; and (9) outcomes (including mortality). While RRs are systematic in nature, they are distinct from systematic reviews in their aim to gather evidence in a timely manner to support decision-making on urgent or high-priority health concerns at the national level. RESULTS: Three medical science databases were searched as the primary source of literature for the RRs: Science Direct, PubMed and OVID (Medline). The search was completed on 31st May 2021 (spanning January 2009-May 2021). At writing, a total of 1,320 articles met eligibility criteria and were included in the final review. CONCLUSIONS: For each RR, the evidence has been organised to review the knowledge area and identify gaps for further research and investment. The series of RRs (published separately within the current series) are designed to support the development of research and translation practice in the field of EDs. They highlight areas for investment and investigation, and provide researchers, service planners and providers, and research funders rapid access to quality current evidence, which has been synthesised and organised to assist decision-making.

The impact of the COVID-19 pandemic and associated public health response on people with eating disorder symptomatology: an Australian study.

OBJECTIVE: People with lived experience of eating disorders (ED) may be particularly vulnerable to the COVID-19 pandemic and associated public health response due to exasperating situations such as social isolation, presence of other mental and physical health conditions, disruptions to treatment, etc. This study investigates the association of the pandemic with ED symptomatology to consider impact and identify risk factors for clinical consideration. METHODS: Participants with self-reported ED diagnosis and/or symptomatology over 16 years were invited to complete an online survey during the first months of the pandemic in Australia. Questions included history of ED, occurrence of co-occurring mental health conditions, change in ED symptoms since the start of the pandemic, and validated measures of ED illness, state mental health and loneliness. RESULTS: Of 1723 participants (mode age 24.9 years, 91.6% identifying as female, EDE-Q Global Score x = 4.08, SD = 1.18, 79.0% reporting co-occurring mental health condition, predominantly obsessive-compulsive disorder and/or anxiety), 88.0% reported an increase in body image concerns, 74.1% in food restriction, 66.2% binge eating and 46.8% driven exercise during the pandemic. Increased ED symptomatology was associated with poorer state mental health (i.e., depression, anxiety, and stress) and loneliness across the ED symptom profile. Most participants were negatively impacted by various aspects of the public health response, more so for those with more acute ED illness as measured by the Eating Disorder Examination Questionnaire (EDE-Q). CONCLUSIONS: Associated with the COVID-19 pandemic is a mental health crisis, particularly for those with a lived experience of an eating disorder. With 40.5% of participants not having sought formal diagnostic assessment and less than half in treatment, this study provides evidence for the detrimental impact of the pandemic on people with a lived experience of an eating disorder, especially for those not yet supported by the health care system.

This study investigates the impact of the COVID-19 pandemic and associated public health response on people with a self-reported lived experience of eating disorders across Australia. A nation-wide online survey of 1723 participants aged 16­80 years indicated eating disorders symptoms increased globally including body image concern (for 88% of participants), food restriction (74%) and binge eating (66%), especially for those reporting more acute eating disorder illness, poorer mental health (including depression, anxiety, and stress) and experience of loneliness. Albeit necessary, several pandemic experiences were identified as being particularly associated with more acute eating disorder illness such as changes in daily routine, social media reactions, restricted access to support people, and changes to treatment. As less than half of the participants were in treatment at assessment and over 40% had never sought formal diagnosis or treatment, this study highlights the prevalence of unidentified and unsupported people in the community experiencing increase eating disorder symptoms during this pandemic and the need for clinical awareness in general medical and mental health practice.

Supported online cognitive behavioural therapy for bulimia nervosa: a study protocol of a randomised controlled trial.

BACKGROUND: Despite the availability of effective treatments for bulimia nervosa (BN), a number of barriers to accessibility exist. Examples include access to trained clinicians, the expense of treatment, geographical limitations, and personal limitations such as stigma regarding help seeking. Self-help interventions, delivered via a digital platform, have the potential to overcome treatment gaps by providing patients with standardised, evidence-based treatments that are easily accessible, cost-effective, and require minimal clinician support. Equally, it is important to examine the shortcomings of digital interventions when compared to traditional to face-to-face delivery (e.g., high dropout rates) in order to maximise the therapeutic effectiveness of online, self-help interventions. METHODS: A three-arm, multisite randomised controlled trial will be conducted in Australia examining the effectiveness and cost-effectiveness of a newly developed online self-help intervention, Binge Eating eTherapy (BEeT), in a sample of patients with full or sub-threshold BN. The BEeT program consists of 10, multimedia sessions delivering the core components of cognitive behaviour therapy. Eligible participants will be randomised to one of three groups: independent completion of BEeT as a purely self-help program, completion of BEeT alongside clinician support (in the form of weekly telemedicine sessions), or waitlist control. Assessments will take place at baseline, weekly, post-intervention, and three-month follow up. The primary outcome is frequency of objective binge episodes. Secondary outcomes include frequency of other core eating disorder behavioural symptoms and beliefs, psychological distress, and quality of life. Statistical analyses will examine treatment effectiveness, feasibility, acceptability and cost effectiveness. DISCUSSION: There is limited capacity within the mental health workforce in Australia to meet the demand of people seeking treatment for eating disorders. This imbalance has only worsened following outbreak of the COVID-19 pandemic. Further research is required into innovative digital modes of treatment delivery with the capacity to service mental health needs in an accessible and affordable manner. Self-help programs may also appeal to individuals who are more reluctant to engage in traditional face-to-face treatment formats. This study will provide rigorous evidence on how to diversify treatment options for individuals with BN, ensuring more people with the illness can access evidence-based treatment. The study has been registered with the Australia New Zealand Clinical Trials Registry (ANZCTR Registration Number: ACTRN12619000123145p). Registered 22 January 2019, https://www.australianclinicaltrials.gov.au/anzctr/trial/ACTRN12619000123145 .

Identification of high risk and early stage eating disorders: first validation of a digital screening tool.

BACKGROUND: Eating disorders are amongst the deadliest of all mental disorders, however detection and early intervention rates remain extremely low. Current standardised screening questionnaires can be arduous or confronting and are ill-validated for online use, despite a universal shift to digital healthcare. The present study describes the development and pilot validation of a novel digital screening tool (the InsideOut Institute-Screener) for high risk and early stage eating disorders to drive early intervention and reduced morbidity. METHODS: We utilised a mixed cross-sectional and repeated measures longitudinal survey research design to assess symptom severity and recognised parameters of statistical validity. Participants were recruited through social media and traditional advertising, and through MTurk. An Eating Disorders Examination Questionnaire (EDE-Q) global score of 2.3 and assessment of eating disorder behaviours was used to determine probable ED. 1346 participants aged 14-74 (mean [SE] age 26.60 [11.14] years; 73.8% female, 22.6% male) completed the survey battery. 19% were randomised to two-week follow-up for reliability analysis. RESULTS: Strong positive correlations between the IOI-S and both the EDE-Q global (rs = .88) and SCOFF (rs = .75) total score were found, providing support for the concurrent validity of the scale. Inter-item correlations were moderate to strong (rs = .46-.73). Correlations between the IOI-S and two measures of social desirability diverged, providing support for the discriminant validity of the scale. The IOI-S demonstrated high internal consistency (α = .908, ω = .910) and excellent two-week test-retest reliability (.968, 95% CI 0.959-0.975; p ≤ 0.1). The IOI-S accurately distinguished probable eating disorders (sensitivity = 82.8%, specificity = 89.7% [AUC = .944], LR+ = 8.04, LR- = 0.19) and two stepped levels of risk. CONCLUSIONS AND RELEVANCE: The present study provides excellent initial support for the psychometric validity of the InsideOut Institute digital screening tool, which has the potential to streamline early intervention in the hopes of reducing current high morbidity and mortality. Further validation should be undertaken in known clinical populations. Eating disorders are amongst the deadliest of all mental disorders, however detection and early intervention rates remain extremely low. The present study describes the initial psychometric validation of a novel digital screening tool (the InsideOut Institute Screener) for high risk and early stage eating disorders, for self-referral and/or use in primary care. 1346 participants aged 14-74 of all genders completed a survey battery designed to assess common parameters of statistical validity. Strong support was found for the screener's ability to accurately measure eating disorder risk and symptomatology. The screener was highly positively correlated with a well known and extensively validated long form self-report questionnaire for eating disorder symptomatology. This study is a pilot validation and the genesis of a project that aims ultimately to drive early intervention leading to reduced morbidity and mortality rates in this illness group.

Prevalence and management of people with eating disorders presenting to primary care: A national study.

OBJECTIVE: Primary care practitioners are well placed to support diagnosis and appropriate treatment of eating disorders as they are often the first point of contact with the health care system. However, little is known about management of eating disorders in primary care. We aimed to estimate the prevalence of management of eating disorders in primary care and identify how these disorders are managed. METHODS: This study used data from the Bettering the Evaluation of Care of Health programme, which annually surveys 1000 randomly sampled general practitioners in Australia who each record details of 100 successive patient encounters. In total, data were utilised from 1,568,100 primary care encounters between 2000/2001 and 2015/2016. RESULTS: Eating disorders were managed in less than 1% of primary care encounters between 2000/2001 and 2015/2016. When extrapolated to the Australian population, up to 0.32% of the population were managed in primary care for a primary or probable eating disorder. In the majority of encounters where an eating disorder was managed (58.5%), the encounter was initiated for reasons other than the eating disorder itself. Of a group of patients identified with a clinically significant low body mass index (N = 5917), a small number (n = 118) had either no other diagnosis or a related condition that may be indicative of an eating disorder. In encounters where an eating disorder was managed, referrals to a mental health specialist/service, medical specialist and nutritionist/dietician were provided in 20%, 8% and 6% of encounters, respectively. Mental health treatment plans, which provide subsidised access to mental health services, were ascribed in approximately 7.7% of encounters where an eating disorder was managed. CONCLUSION: Primary care provides an opportunity to improve detection and management of eating disorders, particularly when patients present for 'other' issues or with unexplained low body mass index and one or more symptoms related to an eating disorder.

Factors related to length of stay, referral on discharge and hospital readmission for children and adolescents with anorexia nervosa.

OBJECTIVE: This study examined factors related to hospital length of stay (LOS), reported referral on discharge, and hospital readmission, for children and adolescents (C&A) admitted to public hospitals for anorexia nervosa (AN), in a large health jurisdiction in Australia. METHOD: Sociodemographic, illness, treatment, and hospital factors associated with LOS, reported referral to post-hospital treatment, and readmission within 28 days were analyzed for C&A with AN admitted to all New South Wales public hospitals in 2017, using median, multinomial logit and logit models. The sample comprised 289 admissions by 200 C&A aged 9-18 years with a primary or secondary diagnosis of AN. RESULTS: AN as a primary diagnosis and the presence of some physical and mental co-occurring conditions (e.g., malnutrition and obsessive-compulsive disorders) conferred a longer LOS. The majority of admissions were recorded being referred to primary care physicians (59.86%) and relatively small numbers to outpatient mental health services (5.54%) or outpatient eating disorder services (8.30%), with age, area socioeconomic status, and illness factors related to referral type. Male, low socioeconomic status, the presence of some co-occurring illnesses (e.g., adjustment disorder and viral infection), and rural or remote locations increased the likelihood of readmission. DISCUSSION: The findings have implications for service design, in particular the pathway to care from hospital into community for AN. Targeted interventions should consider recognizing and treating physical co-occurring illnesses at presentation to the health system, ensuring appropriate referral to community services, and providing services in socioeconomically disadvantaged and rural or remote areas.

Transitioning to digital first line intervention - validation of a brief online screener for early identification of a suspected eating disorder: study protocol.

BACKGROUND: Only one in four people with eating disorders seeks treatment, and of those who do seek treatment, 20% go on to experience a chronic course. Early intervention has been associated with better prognosis, with those seeking specialised intervention in the early stages of their illness more than twice as likely to achieve remission. Current screening measures typically require expert administration and are rarely validated across a spectrum of DSM-5 eating disorder presentations or for online use. In light of COVID-19 and increasing reliance on telehealth technologies in the intervention and delivery of mental health services, online assessments suitable for self-referral are likely to be the first step to seeking care. InsideOut Institute has developed a 6-item online screening tool for the purposes of identifying eating disorder risk and symptomatology, aimed specifically at increasing help-seeking behaviour in subsyndromal and early presentations. METHODS: This study investigates the reliability and validity of the InsideOut Institute Screener (IOI-S), using a cross-sectional survey research design. Participants aged 14 and over will complete an extensive baseline survey battery for evaluation. 50% of participants will be randomly selected for one follow-up re-test of the IOI-S only, 2 weeks post initial testing. The IOI-S will be analysed for statistical reliability on two parameters: internal consistency and test re-test reliability, and for statistical validity on four parameters: concurrent validity, sensitivity and specificity, convergent and discriminant validity. DISCUSSION: The rapid and ongoing shift to digital intervention has highlighted gaps and opportunities in our pathways to care. Adequate screening for eating disorders is a major gap. This study aims to validate an online screening tool for use in telehealth early intervention, designed for users seeking information for a suspected eating disorder. The screener meets those at risk 'where they are' (i.e. online) and may improve timely referrals to relevant services. This is of particular salience as face-to-face healthcare and traditional frontline interventions are disrupted, and we are challenged to re-design our practices to deliver diagnostic and treatment services in highly adaptive digital contexts.
