Abstract Objectives Eating disorders (EDs) have a worldwide prevalence of 7.8%, with towering mortality rates and high healthcare costs. The current recommended treatment for EDs principally works by directly targeting ED thoughts and behaviours, but recovery rates are low. A multifaceted link between difficulties with emotions and EDs is now widely established, and newer third-wave therapies that aim to address these underlying emotion difficulties are promising. The current study piloted an online emotion self-help intervention which was co-developed with clinicians and people with lived experienced of EDs. The intervention aimed to specifically address difficulties with emotion identification and regulation, as well as unhelpful beliefs about emotions, which are believed to give rise to and maintain ED thoughts and behaviours. Method We recruited 39 people with self-reported EDs to test this intervention over a one-week period. Our participants were asked to complete a series of questionnaires measuring emotion processes and psychopathology on Day 1 (T1) before being given access to the intervention. Participants were then asked to practice the newly acquired skills for seven days, before taking the same questionnaires on Day 9 (T2). We also asked participants to qualitatively report on their experience of the intervention. Results We found significant improvements in ED psychopathology (ED-15), depression (PHQ-9), and anxiety (GAD-7) pre- to post-intervention, with medium to large effect sizes. All our emotion variables namely alexithymia (TAS-20), difficulties regulating emotions (DERS-SF), and unhelpful beliefs about emotions (EBQ) also showed significant changes post-intervention with medium to large effect sizes. Most importantly, changes in emotion regulation processes were linked to improved eating psychopathology. The qualitative analysis corroborated this finding, highlighting how the intervention helped them form new beliefs about emotions, which helped them reduce ED behaviours. Discussion Significant improvements in emotion processing and regulations, as well as psychopathology, along with positive qualitative feedback, suggest that the intervention effectively met its aims of increasing awareness of the link between emotions and eating psychopathology, providing help to identify and regulate emotions, and normalising emotional experiences. While our results are promising, further research is required to assess its effectiveness longer term and in clinical settings.

Plain English Summary Autistic individuals seem to be at higher risk of developing eating disorders (ED)—even just having autistic traits seems to elevate risk of ED, although we do not understand why. One possibility is that autism and autistic traits are closely related to alexithymia, a difficulty identifying and describing your emotions, and it may be this that increases risk of ED. To test this, we explored relationships between autistic traits and ED symptoms in men and women with ED, who completed an online survey. In men, we found that autistic traits were associated with ED symptoms because they were associated with alexithymia, and alexithymia was associated with ED symptoms because it was associated with anxious/depressive symptoms. The same was true in women, but anxious/depressive symptoms were also associated with ED symptoms in their own right. While these findings need to be investigated in more thorough longitudinal approaches, they suggest that pathways to ED differ slightly between men and women, autistic and non-autistic, and that therapeutic interventions should also differ. In both sexes, the fact that alexithymia was associated with ED symptoms and those of other mental illnesses that seemed to contribute to ED, suggests that it should be targeted in interventions.

Plain English summary While eating disorders (EDs) are more common in females, males also suffer from these conditions and are generally neglected in research around EDs. Difficulty identifying and managing emotions is believed to be important in the development and maintenance of EDs, but as studies have been conducted mostly in females, it is unclear whether this is also true for males. We recruited 1604 participants (631 were males, and 329 were diagnosed with EDs comprising 109 males and 220 females) and compared how males and females processed and regulated their emotions. We found that males with EDs, like their female counterparts, suffered from difficulties identifying and regulating their emotions, though they showed a slightly different profile of difficulties. While difficulties with emotions were associated with ED behaviours in both sexes, difficulties using reappraisal, an emotion regulation strategy where one reinterprets an event from a different perspective, were associated with restraint in females but not in males. This suggests that while interventions to help with emotional functioning could be beneficial for both women and men with EDs, the different emotional profiles of men with EDs must be considered, as interventions targeting particular emotional processes (e.g. reappraisal) may be relevant for women but not men.

Abstract Objective The Covid-19 pandemic has wrought disruption to everyday life and services, and emerging evidence suggests that those with eating disorders (EDs) are likely to experience marked distress and exacerbation of their symptoms. However, little is known around the most relevant factors to symptom change; whether certain emotion regulation and coping strategies are linked to better outcomes; and how people with EDs are adjusting to psychological interventions moving online. Method In a mixed-method design, we collected qualitative and quantitative data from 207 (76 males) self-selected UK residents with self-reported ED, who described and ranked impacts of the pandemic on their symptoms. Regression analysis examined whether emotion regulation strategies were associated with self-reported symptom change, ED symptomatology, and negative emotional states. Thematic analysis explored participants’ experiences of the pandemic, particularly factors affecting their ED, coping strategies used, and experiences of psychological intervention. Results Most participants (83.1%) reported worsening of ED symptomatology, though factors affecting symptom change differed between specific EDs. Emotion regulation, such as having fewer strategies, poorer emotional clarity, and non-acceptance of emotions, explained nearly half of the variance in emotional distress during the pandemic. Qualitative findings indicated that difficult emotions (such as fear and uncertainty), changes to routine, and unhelpful social messages were triggering for participants during the pandemic. While some participants described employing positive coping strategies (such as limiting social media exposure), many reported using ED behaviours (among other maladaptive strategies, like alcohol use) to cope with the pandemic. Finally, loss of treatment support, feeling underserving of support and experiencing a ‘detached connection’ online were further exacerbating factors for these participants. Discussion While our sample was self-selected and may not represent all people with EDs, our results suggest that people with EDs have been strongly affected by the pandemic. Some aspects of online treatment were found to be beneficial but our findings suggest it also needs some improvement. Our paper discusses implications for online treatment such as taking into account personal circumstances and, in a time where people have limited control over the antecedents of negative emotion, the need to develop skills to manage emotions when they arise.
