Perceived Facilitators and Barriers to Engaging with a Digital Intervention among Those with Food Insecurity, Binge Eating, and Obesity

Barriers and facilitators affecting treatment uptake behaviours for patients with eating disorders: A systematic review synthesising patient, caregiver and clinician perspectives

OBJECTIVE

A significant treatment gap exists between persons affected by eating disorders (ED), and those engaging with treatment services. This systematic review aims to provide a thorough understanding of the barriers and facilitators affecting eating disorder treatment engagement, including a synthesis of the perspectives of patients, caregivers and healthcare professionals.

METHOD

This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies were retrieved from three databases (PubMed, PsycInfo, Web of Science) and were screened and assessed independently by two raters. A thematic analysis was completed to determine the key barriers and facilitators reported by the included studies.

RESULTS

A total of 73 studies were included. From these studies, 12 barriers and 13 facilitators were identified. Patients reported stigma, shame and guilt as the most prominent barrier affecting their engagement with treatment services. Meanwhile, caregivers and healthcare professionals reported a lack of eating disorder knowledge of clinicians as the most important barrier. Positive social support was cited as the most prominent facilitator to promote help-seeking.

DISCUSSION

Patients, caregivers and healthcare professionals experience a variety of barriers and facilitators to treatment uptake for ED. Interventions addressing barriers and facilitators could increase treatment engagement, including anti-stigma campaigns and positive peer-support interventions.

Challenges and adaptations for a cluster-randomized control trial targeting parents of pediatric cancer survivors with obesity during the COVID-19 pandemic

Although the COVID-19 pandemic has increased the importance of digital technology in clinical trial implementation, there is a dearth of literature reporting on challenges and strategies related to multi-site randomized controlled trials (RCTs) among pediatric cancer survivors during the pandemic. This paper discusses challenges faced in the implementation of the NOURISH-T+ trial so far (December 2019-March 2022) and describes adaptations made as a result of these disruptions in the areas of recruitment, data collection, and overall engagement. This reflection is based on a multisite cluster-RCT that aims to examine whether an intervention targeting parents as agents of change to promote healthy eating and physical activity in pediatric cancer survivors, NOURISH-T+ (Nourishing Our Understanding of Role modeling to Improve Support and Health for Healthy Transitions), reduces body mass and improves health behaviors compared to Brief NOURISH-T (Enhanced Usual Care/EUC). The COVID-19 pandemic has created and exacerbated challenges for our trial related to participant recruitment and engagement, technology access and literacy, and data collection and management, as well as COVID-related challenges (e.g., Zoom fatigue). Strategies used to address these challenges might prove helpful in future virtual or hybrid RCTs, including developing trust and rapport with participants, providing support through multiple routes of dissemination, and using data management applications (e.g., REDCap™) for automation and project management. Extra efforts to build families' trust and rapport, offering multiple routes of support, and automating as many tasks as possible are critical to ensuring the continuation of high-quality clinical trials during the COVID-19 pandemic.

Patient perceptions of the relationship between food insecurity and eating disorder treatment: A qualitative exploration

INTRODUCTION

Independently, food insecurity (FI) and binge-spectrum eating disorders (B-ED) are widespread problems; moreover, FI is associated with elevated binge-eating symptoms. However, extant research has not explored how FI may contribute to the development of B-ED symptoms, nor potential impacts of FI on eating disorder treatment.

METHOD

This study aimed to qualitatively examine (1) mechanisms by which FI impacts B-ED development and maintenance, (2) effects of past and/or present FI on ED treatment, and (3) participant recommendations for addressing FI in future B-ED treatment. Fourteen individuals who completed B-ED treatment and endorsed FI completed a 30-min interview about their experiences.

RESULTS

Participants reported that FI contributed to binge eating by maintaining dietary restraint-binge-eating cycle and by leading them to use food as a coping mechanism or for emotional comfort, both in past and present situations. Present FI interfered with treatment, particularly with adhering to treatment recommendations and food purchasing choices, however, participants did not report any impact of past FI on B-ED treatment. Participants reported that rarely was FI addressed as part of treatment; most participants suggested that future treatments work to (1) assess and problem solve present FI to minimize interference and (2) assess and understand the influence of past FI on current symptoms to validate the function of behavior.

DISCUSSION

These findings provide qualitative support that FI may reinforce B-ED symptoms and present FI may interfere with treatment. This study emphasizes the need for assessment and consideration of FI as a factor when treating individuals with B-EDs.

Integrating a web-based intervention into routine care of binge-eating disorder: Study protocol for a randomized controlled trial

BACKGROUND

Although binge eating disorder (BED) is the most common eating pathology and carries a high mental and physical burden, access to specialized treatment is limited due to patient-related barriers and insufficient healthcare resources. Integrating web-based self-help programs into clinical care for BED may address this treatment gap by making evidence-based eating disorder interventions more accessible.

METHODS

A two-armed randomized controlled trial will be conducted to evaluate the effectiveness of a web-based self-help intervention for BED in routine care settings. Patients aged 18-65 years fulfilling the diagnostic criteria for BED (N = 152) will be randomly allocated to (1) an intervention group receiving a 12-week web-based self-help program or (2) a waitlist control group with delayed access to the intervention. The primary outcome will be the number of binge eating episodes. Secondary outcomes include global eating pathology, functional impairments, work capacity, well-being, comorbid psychopathology, self-esteem, and emotion regulation abilities. Measurements will be conducted at baseline (study entrance), 6 weeks after baseline (mid-treatment), and 12 weeks after baseline (post-treatment). To capture outcomes and treatment mechanisms in real-time, traditional self-reports will be combined with weekly symptom monitoring and ecological momentary assessment.

DISCUSSION

Evaluating the effectiveness of web-based interventions is essential to overcome the treatment gap for patients with BED. When adequately integrated into standard care, these programs have the potential to alleviate the high burden of BED for individuals, their families, and society.

Applying a web-based self-help intervention for bulimia nervosa in routine care: Study protocol for a randomized controlled trial

BACKGROUND

Individuals with bulimia nervosa (BN) experience persistent episodes of binge eating and inappropriate compensatory behavior associated with impaired physical and mental health. Despite the existence of effective treatments, many individuals with BN remain untreated, leading to a high burden and an increased risk of chronicity. Web-based interventions may help facilitate access to evidence-based treatments for BN by reducing barriers to the health care system.

METHODS

The present study will investigate the effectiveness of a web-based self-help intervention for BN in a two-armed randomized controlled trial. Individuals diagnosed with BN (N = 152) will be randomly assigned to either (1) an intervention group receiving a 12-week web-based intervention or (2) a waitlist control group with delayed access to the intervention. Further assessments will be scheduled 6 (mid-treatment) and 12 (post-treatment) weeks after baseline. Changes in the number of binge eating episodes and compensatory behaviors will be examined as primary outcomes. Secondary outcomes include global eating pathology, functional impairments, well-being, comorbid psychopathology, self-esteem, and emotion regulation abilities.

DISCUSSION

Adding web-based interventions into routine care is a promising approach to overcome the existing treatment gap for patients with BN. Therefore, the current study will test the effectiveness of a web-based intervention for BN under standard clinical care settings.
