Effectiveness of an online self-help program, expert-patient support, and their combination for eating disorders: Results from a randomized controlled trial

Sensitivity to change in well-being and health-related quality of life in adults with eating disorder symptoms: ICECAP-A versus EQ-5D-5L

OBJECTIVE

Economic evaluations of treatments help to inform decisions on allocating health care resources. These evaluations involve comparing costs and effectiveness in terms of quality of life. To calculate quality-adjusted life years, generic health related quality of life is often used, but is criticized for not being sensitive to change in mental health populations. Another approach, using experienced well-being measured through capabilities with the ICECAP-A, has been proposed as an alternative. The aim of this study was to investigate whether changes in individuals with eating disorder (ED) symptoms can be better captured using health related quality of life (EQ-5D-5L) or well-being (ICECAP-A).

METHOD

Measurements at two time points with an interval of 1 year were used from a sample of 233 participants with self-reported ED symptoms. An analysis of variance was used to test whether the EQ-5D-5L and ICECAP-A differed in sensitivity to change over time. In order to compare the two questionnaires in terms of clinically significant outcome, the reliable change index and clinical cut-off score were calculated.

RESULTS

The two questionnaires did not differ in sensitivity to change. More individuals had recovered but also more had deteriorated according to the EQ-5D-5L compared to the ICECAP.

DISCUSSION

The present study revealed no differences in sensitivity to change in health-related quality of life or well-being in individuals with ED symptoms in the context of mild clinical change. Results corroborated the pervasiveness of low quality of life in this population, even after alleviation of ED symptoms.

PUBLIC SIGNIFICANCE STATEMENT

Measuring treatment benefits in terms of improvements in quality of life is an integral part of economic evaluations in health care. It was expected that these treatment benefits would be better captured as changes in well-being (measured with the ICECAP-A) than as changes in health-related quality of life (measured with the EQ-5D-5L) for individuals with ED symptoms. Based on the results of this study, no preference for one of the two approaches was found.

Early evaluation of a DBT-informed online intervention for people with eating disorders

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.

Predictors and moderators of three online interventions for eating disorder symptoms in a randomized controlled trial

OBJECTIVE

To optimize treatment recommendations for eating disorders, it is important to investigate whether some individuals may benefit more (or less) from certain treatments. The current study explored predictors and moderators of an automated online self-help intervention "Featback" and online support from a recovered expert patient.

METHODS

Data were used from a randomized controlled trial. For a period of 8 weeks, participants aged 16 or older with at least mild eating disorder symptoms were randomized to four conditions: (1) Featback, (2) chat or e-mail support from an expert patient, (3) Featback with expert-patient support, and (4) a waitlist. A mixed-effects partitioning method was used to see if age, educational level, BMI, motivation to change, treatment history, duration of eating disorder, number of binge eating episodes in the past month, eating disorder pathology, self-efficacy, anxiety and depression, social support, or self-esteem predicted or moderated intervention outcomes in terms of eating disorder symptoms (primary outcome), and symptoms of anxiety and depression (secondary outcome).

RESULTS

Higher baseline social support predicted less eating disorder symptoms 8 weeks later, regardless of condition. No variables emerged as moderator for eating disorder symptoms. Participants in the three active conditions who had not received previous eating disorder treatment, experienced larger reductions in anxiety and depression symptoms.

DISCUSSION

The investigated online low-threshold interventions were especially beneficial for treatment-naïve individuals, but only in terms of secondary outcomes, making them well-suited for early intervention. The study results also highlight the importance of a supportive environment for individuals with eating disorder symptoms.

PUBLIC SIGNIFICANCE

To optimize treatment recommendations it is important to investigate what works for whom. For an internet-based intervention for eating disorders developed in the Netherlands, individuals who had never received eating disorder treatment seemed to benefit more from the intervention than those who had received eating disorder treatment, because they experienced larger reductions in symptoms of depression and anxiety. Stronger feelings of social support were related to less eating disorder symptoms in the future.

The effectiveness of lived experience involvement in eating disorder treatment: A systematic review

OBJECTIVE

This systematic review sought to understand the effectiveness of lived experience mentoring, by people recovered from an eating disorder, with clinical samples currently receiving eating disorder treatment.

METHODS

The systematic review was conducted using PsycINFO, MEDLINE, Scopus, and ProQuest Dissertations and Theses Global and reviewing reference lists of included papers. Articles were included if they: (1) were intervention studies that included peer (recovered from an eating disorder) involvement, (2) delivered the intervention to clinical samples (or carers with direct involvement in treatment), (3) were in English, and (4) included quantitative results.

RESULTS

Eleven studies were included across randomized control trials (RCTs), case series, and a case study; there was variation in quality. Findings varied considerably with some concluding that lived experience mentoring led to significant improvements for mentees, while other studies found no significant differences. Mentor outcomes were often not evaluated. Of those that did assess mentors, there is preliminary evidence for some benefits to participation but also the potential for harm.

DISCUSSION

There is a need for further research in this area using high-quality RCTs that address the risk of bias. It is important that lived experience peer mentors are monitored on key outcomes, provided with adequate training and ongoing supervision, and are reimbursed for their involvement.

PUBLIC SIGNIFICANCE

This systematic review is the first review to focus on the use of peer mentors recovered from an eating disorder contributing to interventions for people receiving treatment for an eating disorder. All included studies present quantitative results. Given the emerging interest of lived experience mentoring, understanding its effectiveness for both mentees and impacts on mentors continues to be of critical importance.

Longer-term impact of COVID-19 among individuals with self-reported eating disorders in the United States, the Netherlands, and Sweden

OBJECTIVE

We assessed eating disorder (ED) illness status, symptomatology, treatment access, anxiety, and depression in the first year of the COVID-19 pandemic among individuals with a pre-existing ED in the United States (US), the Netherlands (NL), and Sweden (SE).

METHODS

Participants completed online surveys in April-July 2020, at the early stage of the pandemic, and one year later. At one-year follow-up, we added questions addressing retrospective changes in ED symptoms, treatment, and anxiety/depression since the start of the COVID-19 pandemic. We present descriptive statistics and assess change in ED symptomatology, treatment, and anxiety/depression among those with an active or lingering ED.

RESULTS

Participants (US n = 132; NL n = 219; SE n = 702) were mostly young and female with a history of anorexia nervosa (>60% in all three countries). Across countries, respondents reported impact of COVID-19 on ED symptoms at both time points, with improvement in US and NL at one-year follow-up, and stable but less impact on ED symptoms in SE. Furthermore, at one-year follow-up, roughly half of those in treatment reported reduced treatment access and quality, and the majority of the sample reported increased anxiety and depressive mood since the start of the pandemic.

DISCUSSION

Our findings suggest that the self-perceived impact of COVID-19 changed over time but remained concerning even one year after the start of the pandemic. Clinicians, community organizations, and policy makers are encouraged to address potentially changing treatment needs in the face of public health emergency events.

PUBLIC SIGNIFICANCE

Our findings suggest that the impact of COVID-19 on individuals with eating disorders decreased over time but remained concerning even one year after the start of the pandemic and that the impact differed across countries. Clinicians, community organizations, and policy makers are encouraged to incorporate this knowledge to address potentially changing treatment needs in the face of public health emergency events.
