Understanding the Challenges Faced by Carers of Individuals with Co-occurring Autism and Eating Disorders
Caring for someone with an eating disorder (ED) can be a profoundly challenging experience, often taking a significant personal toll on the carer. When an individual also has Autism Spectrum Condition (ASC), the complexities multiply, potentially leading to additional burdens and unique support needs for carers. This article delves into the experiences of carers of individuals with co-occurring ASC and EDs, highlighting the specific challenges they face and exploring ways healthcare services can better support this often-overlooked population.
The Intertwined Challenges of Eating Disorders and Autism
Eating disorders are characterized by disturbed eating, food consumption, and related behaviors that significantly impact physical and psychosocial health. The typical onset of EDs occurs during adolescence or early adulthood, a time when individuals may still reside at home and rely on family support. As ED treatments often occur on an outpatient basis, parents may assume the role of implementing and ensuring treatment compliance at home. Consequently, the development of an ED in a young person can profoundly impact their parents, who often become carers and play a crucial role in their treatment.
Carers of people with EDs consistently report high levels of psychological distress and perceived burden, driven by unmet practical and emotional support needs. Caring for someone with an ED may also entail significant financial costs for families, potentially leading carers to reduce their working hours to provide support. The pressures associated with this experience can lead to unhelpful coping strategies, including accommodating or enabling ED behaviors and exhibiting high levels of expressed emotion (emotional overinvolvement, hostility, over-protectiveness, or controlling behavior), which may contribute to poorer family functioning and perpetuate the ED itself.
In recognition of the vital role carers play in ED treatment and recovery, especially for younger individuals, NICE guidelines for ED services in the UK stipulate that clinicians should assess carer needs and offer appropriate support and psychoeducation. In line with this, various interventions designed to support carers and families of people with EDs have been developed.
Autism Spectrum Condition (ASC) is a neurodevelopmental condition characterized by persistent difficulties in social interaction and social communication, as well as restricted and repetitive patterns of behavior, interests, or activities. Research indicates that autistic traits are heightened in ED populations, particularly in those with anorexia nervosa (AN). Gold-standard observational diagnostic measures combined with developmental assessments suggest that autism prevalence in AN may be around 10%, compared to a general population prevalence of approximately 1%.

Individuals with both an ED and ASC may face additional challenges compared to their neurotypical peers, including sensory problems motivating food restriction, difficulties engaging in treatment due to communication differences, and high levels of cognitive rigidity making it difficult to change ED-related behaviors and cognitions.
The Carer's Perspective: A Qualitative Study
A qualitative study was conducted, utilizing peer interviews, to explore the experiences of carers of individuals with co-occurring ASC and EDs. Eleven carers participated in interviews about their experiences, their views on existing support systems, and potential improvements. The study took place during the initial UK coronavirus lockdown, and the impact of the lockdown also emerged as a topic during the interviews.
Carers of loved ones with both ASC and EDs described the experience as having a significant personal impact on their lives, but also experienced a lack of support from healthcare services. There was a perception that caring for someone with both ASC and EDs presents additional challenges compared to caring for someone with an ED only, and that this population therefore requires specialized support.
The primary aim of this study was to use qualitative interviews to further explore the support needs of carers of loved ones with co-occurring ASC and AN, and to investigate in more detail carer views on how this population can best be supported. In the context of previous findings indicating a perceived lack of support and alienation from existing ED services, the existing study used a peer interviewing approach, in which the interviewer (shared first author MO) was also a carer of a young person with autism.
Key Findings from the Study
Several key themes emerged from the interviews with carers:

- Lack of recognition and understanding of ASC: Nearly all carers described difficulties getting an autism diagnosis for their loved one, or not recognizing their child’s autism spectrum features due to an overshadowing mental health problem. All carers (n = 11) recalled that their loved one only received an autism diagnosis after receiving treatment for mental health problems, most commonly AN.
- Increased burden and stress: The addition of an autism diagnosis may present challenges to carers of people with EDs. Similarly to AN, parents of children with ASC experience high levels of perceived burden and distress relating to their caregiving role that are closely linked to unmet needs. Research suggests that parents of children with ASC may experience a lower quality of life compared to parents of children with mental health problems. This likely reflects the nature of ASC: unlike mental health problems, autism is a neurodevelopmental condition that will be present across the individual’s lifetime, and is associated with continuing difficulties with daily living into adulthood.
- Need for specialized support: Carers expressed a strong belief that caring for someone with both ASC and EDs requires specialized support tailored to the unique challenges presented by this comorbidity. They felt that existing ED services often lack the expertise to address the specific needs of individuals with autism, leading to frustration and a sense of isolation.
- Impact of the COVID-19 pandemic: The COVID-19 pandemic exacerbated the challenges faced by carers, with disruptions to ED treatment services and increased social isolation.
Implications for Support and Intervention
The findings of this study highlight the urgent need for improved support and interventions for carers of individuals with co-occurring ASC and EDs. Key recommendations include:
- Increased awareness and training for healthcare professionals: Healthcare professionals need to be better equipped to recognize and understand the complexities of co-occurring ASC and EDs. This includes training on autism diagnostic criteria, communication strategies, and adaptations to ED treatment approaches.
- Development of specialized services: Specialized services specifically designed to address the needs of individuals with both ASC and EDs are crucial. These services should incorporate autism-specific interventions, such as sensory integration therapy and social skills training, alongside traditional ED treatment approaches.
- Enhanced support for carers: Carers need access to practical and emotional support, including peer support groups, psychoeducation, and respite care. Support should be tailored to the specific challenges of caring for someone with both ASC and an ED.
- Early identification and intervention: Early identification of autism in individuals with EDs is essential to ensure they receive appropriate and timely support. Mental health professionals should routinely screen for autism in individuals presenting with EDs, particularly those with atypical presentations or treatment resistance.
- Further research: More research is needed to understand the specific needs of individuals with co-occurring ASC and EDs and to develop effective interventions for this population.
Study Methodology
This study employed a qualitative design, utilizing semi-structured peer interviews with carers of people with a diagnosis of an ED and autism. A total of 11 carers participated in the interviews. Four carers were recruited as their child was receiving support from the PEACE pathway (Pathway for Eating disorders and Autism developed from Clinical Experience) at the South London and Maudsley (SLAM) National Health Service (NHS) Trust National ED service. The PEACE pathway is a novel specialist ED treatment pathway for individuals with diagnosed or suspected autism. Participants were considered eligible if they had current caring responsibilities for someone with diagnoses of both an ED and ASC.
For participants recruited from the PEACE pathway, diagnoses were confirmed from clinical notes. One participant’s child did not yet have an official ASC diagnosis, but had scored positively on a gold-standard diagnostic assessment (the Autism Diagnostic Observational Schedule). For participants recruited on social media, diagnoses were self-reported by the carers (typically obtained from autism specialist clinical services) only and not further validated by our research team.
All authors read interview transcripts and regularly met to discuss the data, until it was felt that data saturation had been reached. Due to the COVID-19 pandemic, all interviews were carried out virtually by MO between March and July 2020. The interviews were initiated using a pre-developed interview schedule, based on previous research that explored carers’ needs by the present research team. The schedule was then revised iteratively over the course of the interviews to follow the concerns of participants. The Interviews were conducted over the telephone, or using Microsoft Teams or Zoom software, according to the carer’s preference, and lasted 30-40 min (mean interview length 35 min). All interviews were recorded and transcribed by MO. Data collection and analysis were conducted in parallel and recruitment ceased when we reached inductive theoretical saturation, the point at which no new themes or sub-themes were emerging from the data.
A total of 11 people participated in the interviews. All were parents of a child or adult with autism and an ED: three were fathers, and eight were mothers. Three participants were full time carers for their child, six were employed, and two were retired. Carer ages ranged from 38 to 74 years, with a mean age of 55 years. The people cared for by the participant comprised three males and eight females. Their ages ranged from 12 to 36 years, with a mean age of 23 years. According to parent reports, all patients had been diagnosed with ASC (mean diagnosis age 16.63 years), were verbal, and diagnosed with an ED (mean diagnosis age 13.13 years). Nearly all patients were diagnosed with restrictive AN (n = 9): One patient had a diagnosis of binge-purge AN, and One patient had received ED treatment due to binge eating disorder (BMI in obesity range). All patients had additional mental health difficulties: all parents reported their child experiencing anxiety symptoms, n = 7 had been diagnosed with obsessive-compulsive disorder, n = 4 had a diagnosis of borderline personality disorder, and n = 2 had a diagnosis of body dysmorphic disorder. One patient was reported to have a comorbid diagnosis of pathological demand avoidance (this is behavioural descriptor not in the current DSM or ICD diagnoses).

Data was analysed using thematic analysis. M.O., E.K. and K.T. read and re-read the transcripts in order to familiarise themselves with the data, and to increase sensitivity to key themes across the data set. In the second phase, these authors met to discuss the coding framework. The codes were based on the perceived relevance of the data to the authors’ pre-existing research aims: the researchers were following a structured set of questions which had been developed in a previous research study. Although participants were not directly asked about the pandemic, seven out of the 11 participants (n = 7, 63.6%) discussed the impact of lockdown during the interviews. Therefore, specific codes were developed to reflect this topic. First author M.O. then applied these codes to the data, and collated data for each code. In the third phase, all authors reviewed the collated coding data and met to evaluate possible themes, which helped raise awareness to alternative interpretations of the data. Explicit and semantic themes were identified as the participants were interviewed using specific questions. Theme identification was also based on the perceived relevance to the research aims. Themes were then subsequently reviewed by authors and defined. All of the participants highlighted the additional challenges that this particular comorbidity brought to caring for their loved ones.
