Early intervention in eating disorders: a parent group approach

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.

Recognition and duration of illness in adolescent eating disorders: Parental perceptions of symptom onset

AIM

To understand the earliest parent reported signs suggesting their child may have an eating disorder (ED), and to quantify time from symptom onset to specialist assessment.

METHODS

This is a secondary analysis of data derived from parents of 78 young people presenting to a British community ED service who completed a questionnaire asking when they first noticed their child displaying (a) a change in eating pattern, (b) weight concerns, (c) shape concerns. Parents were also asked to describe the first thing they noticed in terms of possible ED symptoms.

RESULTS

Mean age was 14.9 (SD: 1.58), 94% were female with diagnoses of anorexia nervosa (n = 50), bulimia nervosa (n = 10) and atypical anorexia nervosa (n = 18). Weight and shape concerns were most often noticed over a year prior to assessment (mean 12.7 months [SD: 12.8] and 13.3 months [SD: 13.2], respectively), with eating pattern change observed a mean of 9.7 months (SD: 7.6) before referral to specialist care. Seven main themes were developed from parents' descriptions of their child's symptoms: (1) eating pattern change, (2) shape concern, (3) weight concern, (4) observed weight loss, (5) binge eating/compensatory behaviours, (6) other mental health concerns and (7) physical symptoms.

CONCLUSIONS

The most common parental concerns were eating pattern change, specifically their child becoming more rigid/rule-bound with regard to eating and dietary restraint. Such external changes are likely observed before physical changes such as weight loss, offering potential for early identification by parents, primary care and other professionals, with implications for improved prognosis.

Is guided self-help family-based treatment for parents of adolescents with anorexia nervosa on treatment waitlists feasible? A pilot trial

OBJECTIVE

The aim of the study was to assess the feasibility (recruitment and retention) of an online 12-session guided self-help family-based treatment (GSH-FBT) for families on the waitlist for face-to-face FBT utilizing trainee psychologists to assist carers of children with anorexia nervosa (AN) or atypical AN.

METHOD

The primary outcomes were feasibility of GSH-FBT for families on the waitlist and secondary exploratory outcomes examined improvement of child and parental function.

RESULTS

Of 187 eligible families on the waitlist, 24 (13%) expressed interest in the study; 16 (67%) of these families completed baseline, 13 (54%) completed GSH-FBT over a 6-month recruitment period. Children (mean age = 13.92, SD = .86; mean body mass index [BMI] centile = 29.47, SD = 24.80) had an average weight gain of 6 kg (BMI centile effect size = 2.61, 95% CI: 1.77-3.44) and a decrease in eating disorder behaviors (effect size = 1.11, 95% CI: .27-1.95). Improvements also occurred for general mood and behaviors in the child, and the impact of eating disorder symptoms on their functioning. Parents reported improvements in knowledge, skills, and confidence in managing AN.

DISCUSSION

Use of this low-cost intervention while families are on the waitlist for FBT is engaging and useful but strategies to improve initial recruitment are needed.

PUBLIC SIGNIFICANCE STATEMENT

Although most eligible families did not enroll in an online 12-session guided self-help family-based treatment for families on the waitlist for face-to-face FBT for anorexia nervosa, families who participated found it engaging. The children experienced improvements in BMI centile, eating and behavior. Parents reported increased confidence, knowledge, and skills. We need to examine how families can be encouraged to participate on online training when on waitlists for treatment.

Development of evidence-informed bridge programming to support an increased need for eating disorder services during the COVID-19 pandemic

Over the course of the COVID-19 pandemic, rates of eating disorders have increased, further straining systems of care that were already overburdened. The current paper describes novel interventions, largely informed by Family-Based Treatment (FBT), that were implemented by a tertiary specialist adolescent eating disorders service. In response to the pandemic, programming was designed to bridge access to care while waiting for availability of evidence-based therapy. The Brief Psychology Consultation Clinic provides several sessions to patients and families, focused on psychoeducation and problem-solving informed by FBT and other evidence-based therapies. Two groups, the FBT Caregiver Workshop Series and FBT Caregiver Support Group, provide psychoeducation and support for caregivers of youth with eating disorders. Perceived strengths and benefits of these services, as well as barriers to implementation and future research directions are discussed.

A qualitative examination of adolescent and parent perspectives on early identification and early response to eating disorders

This qualitative study examined adolescent and caregiver perspectives on identification and early response in emerging eating disorders. Fifteen female-identified adolescents with an eating disorder diagnosis (M age = 15.20 years; 93% White; 20% Hispanic) and 12 caregivers (all biological parents: 1 father, 11 mothers; M age = 51.56 years) participated in semi-structured interviews about their experience identifying and responding to the eating disorder, eventually seeking treatment. Participants were recruited from three eating disorder treatment centers in the United States. Interview responses were coded by three raters using inductive consensual qualitative methods. Results found that parents were typically the first to notice and confront the eating disorder, and weight loss and thinness usually were the earliest symptoms identified. The most common adolescent response to detection was mixed (e.g., relief and anger), and common parental reactions included seeking professional consultation and creating limitations on disordered behaviors (e.g., encouraging eating). Barriers to earlier detection were highlighted (e.g., parental hesitancy to act on suspicions), suggesting that parents need greater support for swift and confident responding. To combat this, parents recommended increasing knowledge of eating disorder symptoms. Parents and adolescents both recommended parent-led monitoring of eating and exercise behaviors to increase the chance of noticing changes and responding quickly with aggressive and supportive action. These experiences provide a framework for early identification and the role of caregiver response, highlighting the need for assertive yet compassionate efforts to combat emerging eating disorders.

PaRent InterventiOn to pRevent dIsordered eating in children with TYpe 1 diabetes (PRIORITY): Study protocol for a feasibility randomised controlled trial

AIMS

Increasing evidence suggests that children and young people with type 1 diabetes (T1D) are at greater risk of disordered eating compared to children without T1D. Disordered eating in T1D has been linked to impaired wellbeing, increased health service use and early mortality. To address this problem, we will co-develop a psycho-education intervention for parents of children and young people with T1D, informed by the Information Motivation Behavioural Skills model.

METHODS

The objective of this study is to assess the feasibility and acceptability of the intervention compared to a waitlist control group using a feasibility randomised controlled trial (RCT) design. We aim to recruit 70 parents of children and young people with T1D (11-14 years), 35 in each arm. Those assigned to the intervention will be invited to participate in two workshops of 2 h each. Parents will be asked to complete outcome measures regarding eating habits, diabetes management, as well as a questionnaire based on the Information Motivation Behavioural Skills model which provides a theoretical foundation for the intervention. These will be completed at baseline, 1- and 3-month post-intervention. Children and young people will be asked to complete questionnaires on their eating behaviours at the same time intervals. Parents randomised to receive the intervention will be invited to take part in interviews to feedback on the intervention and research protocol acceptability.

CONCLUSION

It is anticipated that the psycho-education intervention aimed at parents will help prevent the development of disordered eating in children and young people with T1D and improve parental wellbeing. The results of this feasibility trial will determine whether this intervention approach is acceptable to families living with T1D, and whether a definitive RCT of intervention effectiveness is justified. Qualitative findings will be used to refine the intervention and study protocols.

TRIAL REGISTRATION

This protocol has been registered with ClinicalTrials.gov [Identifier: NCT04741568].

Development and Theoretical Underpinnings of the PRIORITY Intervention: A Parenting Intervention to Prevent Disordered Eating in Children and Young People With Type 1 Diabetes

Children and young people (CYP) with type 1 diabetes (T1D) are twice as likely to develop disordered eating (T1DE) and clinical eating disorders than those without. This has significant implications for physical and mental health, with some eating disorders associated with repeated diabetic ketoacidosis and higher HbA1c levels, both of which are life threatening. There is currently limited psychological support for CYP and families with T1D but increasingly, policy and practice are suggesting disordered eating in T1D may be effectively prevented through psychological intervention. We describe the development and theoretical underpinnings of a preventative psychological intervention for parents of CYP aged 11-14, with T1D. The intervention was informed by psychological theory, notably the Information Motivation Behaviour Skills model and Behaviour Change Technique Taxonomy. The intervention was co-developed with an expert advisory group of clinicians, and families with T1D. The manualised intervention includes two online group workshops, and supplementary online materials. The intervention continues to evolve, and feasibility findings will inform how best to align the intervention with routine care in NHS diabetes teams. Early detection and intervention are crucial in preventing T1DE, and it is hoped that the current intervention can contribute to improving the psychological and physical wellbeing of young people and families managing T1D.

Prevention and early help for eating disorders in young people with type 1 diabetes

There is building evidence that early intervention is key to improving outcomes in eating disorders, whereas a 'watch and wait' approach that has been commonplace among GPs and other healthcare professionals is now strongly discouraged. Eating disorders occur at approximately twice the rate in individuals with type 1 diabetes compared to the general population. In this group, standard eating disorder treatments have poorer outcomes, and eating disorders result in a particularly high burden of morbidity. Therefore, our first priority must be prevention, with early intervention where disordered eating has already developed. Clinicians working in both eating disorders and diabetes specialist services have highlighted the need for multidisciplinary team collaboration and specific training, as well as improved treatments. We review the current evidence and future directions for prevention, identification and early intervention for eating disorders in children and young people with type 1 diabetes.

Facilitators and barriers in anorexia nervosa treatment initiation: a qualitative study on the perspectives of patients, carers and professionals

BACKGROUND

An early psychotherapeutic treatment of anorexia nervosa (AN) is crucial for a good prognosis. In order to improve treatment initiation, knowledge about facilitators and barriers to treatment is needed.

OBJECTIVE

Against this background, we aimed to identify facilitators and barriers from the perspectives of patients, carers and professionals using a qualitative approach.

METHOD

To this end, semi-structured interviews were conducted in triads of female patients with AN aged 14 years and older at the beginning of their first psychotherapeutic treatment, their carers, and referring health care professionals. A modified Grounded Theory approach was used for analysis.

RESULTS

In total, 22 interviews were conducted (n = 6 adults, n = 4 adolescents, 4 full triads). The duration of untreated AN ranged between 30 days and 25.85 years (M = 3.06 ± 8.01 years). A wide spectrum of facilitators and barriers within the patient, the social environment, the health care system and the society were identified. Most prominent factors were 'recognizing and addressing' by close others, 'waiting times and availability' and 'recommendations and referrals' by health care professionals. 'Positive role models for treatment' were perceived as a specific facilitative social influence. Facilitators were more frequently mentioned than barriers and most of the factors seem to hold potential for modifiability.

CONCLUSION

Overall, the findings suggest that early intervention approaches for AN should not only address patients and the health care system, but may also involve carers and successfully treated former patients.

Can you find the right support for children, adolescents and young adults with anorexia nervosa: Access to age-appropriate care systems in various healthcare systems

OBJECTIVE

Anorexia nervosa (AN) often has its onset in childhood or adolescence. However, there is insufficient knowledge regarding access to and utilisation of age-specific clinical diagnostics and treatment.

METHODS

A literature review covering the last 10 years was conducted to provide a narrative review of the current state of research on the detection and treatment of young patients with AN in primary and secondary care.

RESULTS

Most articles were of Western European or US origin. Timely diagnosis of the eating disorder (ED) and treatment options more often depend on the structure and quality of the national health care system than on scientific evidence. Regular paediatric health check-ups and age-appropriate eating disorder services appear to facilitate early diagnosis. Age-specific treatment that also involves the carers is often associated with a higher continuity of care and a better outcome. Although many adolescents require an extension of treatment into young adulthood, individual and health care system-related obstacles in many countries prevent a smooth transition.

CONCLUSION

To improve outcomes in childhood and adolescent AN, age-specific and timely diagnostic and therapeutic procedures are urgently needed.

Early intervention in child and adolescent eating disorders: The role of a parenting group

OBJECTIVE

Parental involvement is emphasised in treatment guidelines for Eating Disorders (ED). The primary aim of this phase II study was to estimate the impact of a parent group intervention delivered immediately post-diagnosis on weight gain and ED psychopathology in a cohort of young people referred to a community ED service. A secondary aim was to identify predictor variables for early treatment response in children whose parents attended the programme.

METHOD

Parents of 64 new cases of Anorexia Nervosa (AN; n = 50) and Atypical Anorexia (AAN, n = 14) attended a 6 week parent group intervention in addition to treatment as usual in which patients were weighed and reviewed, but had no other contemporaneous psychological intervention. Age and gender adjusted BMI (%median [m] BMI) and ED psychopathology at baseline, 6-week and 6-month follow-up were analysed to assess weight gain and identify predictors of outcome.

RESULTS

The intervention was associated with weight gain and improved ED psychopathology by the end of the programme; these gains were sustained at 6 months %mBMI at 6 weeks was the only predictor of outcome (%mBMI) at 6 months.

CONCLUSIONS

This preliminary work highlights the positive benefit of an ED focused parent group early intervention that could be further evaluated.

Do parents perceive the abnormal eating attitudes of their adolescent children with anorexia nervosa?

Parents are often the first to detect the initial signs of anorexia nervosa (AN) and take necessary measures to ensure that their children receive appropriate treatment. The evaluation of AN in adolescence is complicated by taking into account the tendency to minimize and deny the symptoms by adolescents, and the difficulty of parents in detecting the main symptoms. We compared the adolescent and parent scores on measures of disordered eating at initial presentation. The sample consisted of 62 adolescents diagnosed with AN, who attended an eating disorder children's unit. Adolescents completed the Eating Attitudes Test (EAT-40) and their parents the Anorectic Behavior Observation Scale (ABOS). The questionnaire data were collected as part of the routine clinical practice and were obtained from clinical notes. The findings indicate no significant correlations between the EAT-40 and ABOS scores, or between AN subtypes according to parent observation of symptoms. There were significant differences between parents, with mothers reporting higher scores than fathers. This study highlights the importance of psychoeducation for parents on the early signs of AN, in order to improve recognition and diagnosis at initial assessment of their adolescent children in the early phases.

Facilitators and barriers in anorexia nervosa treatment initiation (FABIANA): study protocol for a mixed-methods and multicentre study

BACKGROUND

Anorexia nervosa is a serious disorder, which often takes a chronic course. Early treatment leads to a significantly better prognosis and prevents chronicity. However, existing evidence on facilitators and barriers in anorexia nervosa treatment initiation is scarce.

AIMS

Against this background, the FABIANA study (ClinicalTrials.gov Identifier: NCT03713541) aims to (a) identify potentially modifiable facilitators and barriers from the perspectives of adolescent and adult patients with anorexia nervosa, carers and physicians, (b) develop and test an instrument for the combined assessment of multiple key facilitators and barriers, and (c) quantify the effect of potentially modifiable versus non-modifiable key facilitators and barriers on the duration of untreated illness (DUI) in patients with anorexia nervosa.

METHOD

FABIANA is an observational, mixed-method-study divided into three consecutive substudies each corresponding to one of the study aims. All three substudies will include female patients with anorexia nervosa aged 14 years and older at the beginning of their first psychotherapeutic anorexia nervosa treatment. The qualitative substudy I and the quantitative substudy III will additionally include carers and involved physicians. The recruitment will take place at 20 cooperating study centres throughout Germany, which provide in-patient or out-patient anorexia nervosa specialist care. The DUI will be calculated based on the month of illness onset as determined in validated interviews on lifetime anorexia nervosa symptoms and the therapist-reported date of treatment initiation.

CONCLUSIONS

Strengths and limitations of the retrospective assessment of the DUI will be discussed. The findings of the FABIANA study will contribute to the development of evidence-based early-intervention approaches and the prevention of a chronic course of illness.

Children in Need-Diagnostics, Epidemiology, Treatment and Outcome of Early Onset Anorexia Nervosa

Knowledge of anorexia nervosa (AN) in childhood is scarce. This review gives a state-of-the-art overview on the definition, classification, epidemiology and etiology of this serious disorder. The typical features of childhood AN in comparison to adolescent AN and avoidant restrictive eating disorder (ARFID) are described. Other important issues discussed in this article are somatic and psychiatric comorbidity, differential diagnoses and medical and psychological assessment of young patients with AN. Special problems in the medical and psychological treatment of AN in children are listed, although very few studies have investigated age-specific treatment strategies. The physical and mental outcomes of childhood AN appear to be worse than those of adolescent AN, although the causes for these outcomes are unclear. There is an urgent need for ongoing intensive research to reduce the consequences of this debilitating disorder of childhood and to help patients recover.

From questions to answers: Examining the role of pediatric surveillance units in eating disorder research

Pediatric Surveillance Units (PSUs) provide a unique model for the study of pediatric eating disorders (EDs). Australia, Britain, and Canada have surveillance programs that have generated valuable epidemiological and clinical data on early-onset eating disorders (EOED). The PSUs represent an important collaborative tool that has helped shape our understanding of EOEDs and offers potential to contribute to decisions regarding health resource allocation and public health policy. This paper reviews the role of PSUs as a unique model to study pediatric EDs and its success in translating the knowledge generated by these programs into improving the health of children and adolescents with EDs worldwide.

Assessment and treatment of eating disorders in children and adolescents

Feeding and eating disorders (FEDs) are serious mental health disorders that cause impairments in physical health, development, cognition and psychosocial function and can go undetected for months or years. They are characterised by disturbed eating behaviour associated with concerns about weight and shape or by disinterest in food, phobic avoidance or avoidance due to sensory aspects of food. Restrictive forms of FEDs lead to significant weight loss requiring intervention. Without specific knowledge of these conditions, they can evade detection, delaying time to diagnosis and treatment and potentially influencing outcome. This review article focuses on the key factors involved in the psychiatric assessment and treatment of four feeding or eating disorders (EDs): anorexia nervosa, avoidant-restrictive food intake disorder, bulimia nervosa and binge eating disorder. They have been chosen for discussion as they are most likely to be encountered in both a psychiatric and paediatric setting. It emphasises the importance of a family-focused, developmentally appropriate and multidisciplinary approach to care. It does not address aspects of medical assessment and treatment. Other feeding or EDs not included in this article are pica, rumination disorder, other specified feeding and eating disorder and unspecified feeding and eating disorder.
