A controlled trial assessing the acceptability and efficacy of a yoga-based eating disorder prevention program among division I athletes: Eat Breathe Thrive (EBT)

ABSTRACT Objective This study evaluated the acceptability and effectiveness of the Eat Breathe Thrive (EBT) program as an eating disorder prevention intervention among women collegiate athletes. Method Change over time in eating disorder risk and competencies of positive embodiment were examined in 94 women (n = 48 EBT participants and n = 46 matched-controls) from one National Collegiate Athletic Association (NCAA) Division I-classified university in the United States. Eating disorder risk factors were measured using the Eating Disorder Examination Questionnaire (EDE-Q) and State Trait Anxiety Inventory (STAI). Aspects of positive embodiment were measured using the Multidimensional Assessment of Interoceptive Awareness (MAIA) and The Mindful Self-Care Scale (MSCS). Data were collected through participants’ completion of online surveys across three time-points. Results Repeated measures ANOVAS revealed EBT participants reported experiencing significantly less state anxiety and greater interoceptive body trusting over time relative to matched-controls. No other significant interactions were found. Respondents found the EBT program acceptable. Discussion Acceptability and partial support for integrative, yoga-based, interventions targeting Division I student-athletes is indicated.

Eat Breathe Thrive: an interpretative phenomenological analysis of a yoga-based eating disorder intervention

ABSTRACT A growing body of evidence suggests that yoga-based interventions might aid in the prevention and treatment of eating disorders. The current qualitative study used Interpretative Phenomenological Analysis (IPA) to analyze the nature and degree of impact of a yoga and mindfulness-based eating disorder prevention intervention Eat Breath Thrive (EBT). Data was collected via semi-structured interviews with 16 participants over the age of 18 who took part in the EBT program between 2018 and 2022. Using IPA methodology, and after several rounds of coding, emergent themes were interpreted and organized to develop a theoretical model explaining the mechanism of change experienced and described by EBT participants. The resulting model outlines an experiential progression from psychoeducation and skill development/practice to increased mindful awareness, and empowered state experiences which led to the following outcomes: independent positive action, self-initiated positive state experiences, and increased embodied well-being. Participants reported increased self-compassion and self-acceptance, with decreased emphasis on disordered eating behaviors. Qualitative data is necessary for understanding why yoga works, from an experiential perspective. This study adds to the new, and rapidly expanding body of research supporting the positive effects of yoga and mindfulness on the prevention and treatment of eating disorders.

Differences among feminist and non-feminist women on weight bias internalization, body image, and disordered eating

BackgroundResearch yields mixed results on whether feminist beliefs or self-identification are protective against body image disturbance and eating pathology in non-clinical populations. Further, no studies have examined feminism among those with diagnosed eating disorders. Additionally, previous studies have not examined the relationship between feminist identity and weight stigma. This study investigated these relationships and if there are differences in body image, eating pathology, and weight stigma among feminist identity types in women with eating disorders and college women using ANCOVAs.MethodsParticipants completed self-report measures and were women with eating disorders (N = 100) and college women (N = 240).ResultsSixty-four percent of the women with eating disorders and 75.8% of the college women identified as a feminist. An independent samples t-test found a significantly higher weight bias internalization in the clinical eating disorder sample than in the college women sample. No significant interactions were found between sample type and feminist identity for body image or weight bias internalization. Results were consistent when using a dichotomous feminist identity item and a seven-item continuous feminist identity item.ConclusionsDespite the clear impacts of the intersection of weight status and gender, results from this study suggest that identifying as a feminist is not sufficient to combate weight stigma. Findings highlight the need for further research investigating weight bias internalization within eating disorder prevention efforts and interventions.

A systematic review of reach, adoption, implementation and maintenance of Internet-based interventions to prevent eating disorders in adults.

BackgroundThere is a growing body of research and evidence for the efficacy of Internet-based eating disorder (ED) prevention interventions for adults. However, much less is known about the reach, adoption, implementation and maintenance of these interventions. The RE-AIM (reach, efficacy/effectiveness, adoption, implementation, maintenance) model provides a framework to systematically assess this information.MethodsA literature search was conducted in PubMed, Web of Science and PsycINFO for articles published between 2000 and 2019. Additionally, reference lists of the studies included and existing reviews published until the end of 2020 were searched. Sixty original articles describing 54 individual studies fulfilled inclusion criteria. Data were extracted for a total of 43 RE-AIM indicators for each study. Fostering and hindering factors for reach, adoption, implementation and maintenance were assessed qualitatively.ResultsOverall reporting rates were best for the RE-AIM dimensions reach (62.6%), implementation (57.0%) and effectiveness (54.2%), while adoption (24.2%) and maintenance (21.5%) had comparatively low overall reporting rates. Reporting on indicators of internal validity, such as sample size, effects or description of interventions was better than indicators relevant for dissemination and implementation in real-world settings, e.g. characteristics of non-participants, characteristics and representativeness of settings, and data to estimate cost.ConclusionsBecause most Internet-based ED prevention interventions are provided in a research-funded context, little is known about their public health impact. Better reporting of factors determining external validity is needed to inform dissemination and implementation of these interventions.

Examining weight suppression as a predictor and moderator of intervention outcomes in an eating disorder and obesity prevention trial: A replication and extension study

Weight suppression (WS) predicts future weight gain and increases in eating disorder symptoms in community and clinical samples but has received minimal attention in obesity and eating disorder prevention programs. In a sample of emerging adults (N = 364) in a randomized controlled trial evaluating two obesity and eating disorder prevention interventions versus a control condition, this study aimed to replicate the findings that WS and its interaction with baseline BMI predict increases in weight and eating disorder symptoms and test a novel hypothesis that WS would moderate the effects of the interventions on change in weight and eating disorder symptoms. Participants completed assessments at baseline, post-intervention, 6-, 12-, and 24-months. WS was calculated as the difference between highest lifetime weight and baseline weight. WS interacted with baseline BMI to predict greater weight gain over 24-months, such that those with high WS and lower baseline BMI gained weight most rapidly. WS did not predict eating disorder symptom change and did not moderate the effects of the prevention programs. Given that individuals with WS are at increased risk for weight gain, expressly targeting this high-risk population with evidence-based obesity prevention programs may be useful.

Effectiveness of an Internet Dissonance-Based Eating Disorder Prevention Intervention Among Body-Dissatisfied Young Chinese Women

Body image disturbances are widespread in highly populated, rapidly developing Asian nations such as China, but there are severe shortages of practitioners qualified to treat these issues. In such contexts, validated online interventions offer a potentially viable approach for addressing the lack of treatment resources. In this study, we evaluated effects of the eBody Project, an online, dissonance-based eating disorder prevention program, on functioning among body-dissatisfied young Chinese women. Participating women were randomly assigned to the 6-week eBody Project intervention (n = 191) versus an education brochure control condition (n = 181). Self-report assessments of eating disorder risk factors (body dissatisfaction, thin ideal internalization, depressive symptoms, restrained eating), self-esteem, body appreciation, and disordered eating were completed at baseline, posttreatment, and a 6-month follow-up. There were no intervention differences on outcomes before treatment but eBody Project women experienced significantly larger improvements on all outcomes following treatment and/or at follow-up compared to controls; corresponding effect sizes were small to medium. Results indicated the eBody Project program is a promising intervention for young women at risk for eating disorders in China and provide foundations for broad implementation in low- and middle-income countries where resources for in-person therapy and supervision are limited or unavailable altogether.

Research Review: Effectiveness of universal eating disorder prevention interventions in improving body image among children: a systematic review and meta-analysis.

Increasingly, children are at risk of developing eating disorders. A systematic review and a meta-analysis were conducted to examine the effectiveness of universal eating disorder prevention interventions in improving body image, internalization of appearance ideals, and self-esteem among children aged 5-17years old. Nine electronic databases were systematically searched from each database's point of inception to March 2019. The Cochrane Risk of Bias tool assessed each study's risk of bias, while the GRADE approach judged the overall evidence for each review outcome. A meta-analysis was conducted using the random-effect model to obtain standardized mean differences with 95% confidence intervals under the inverse variance method. Heterogeneity was assessed using I2 statistic and Cochran's Q chi-squared test. Publication bias was assessed using funnel plots. A total of 24 studies (22 trials) were included in this review. Universal interventions were found to be effective in improving children's body esteem, self-esteem, and internalization of appearance ideals at postintervention and at follow-up timepoints. Subgroup analyses found that girls benefited more from these interventions than boys. Multisessional interventions with an optimal duration of approximately one month were found to be more effective. The findings encourage the incorporation of universal preventive interventions into school curricula to benefit most children. Laypeople such as teachers can deliver these interventions, but content experts should address topics on body dissatisfaction. Due to the low quality of evidence, as accorded by the GRADE approach, current findings should be validated by future research.

Participant feedback from peer-led, clinician-led, and internet-delivered eating disorder prevention interventions.

This article examines qualitative participant feedback to clinician-delivered groups, peer-delivered groups, and an Internet version of a dissonance-based eating disorder prevention program from a controlled trial. These data have not been systematically examined and can inform the refinement and implementation of eating disorder prevention programs. Feedback was collected from body dissatisfied young women (N = 680; M age = 22.2, SD = 7.1) randomized to a clinician-led group, peer-led group, Internet version of this prevention program or to an educational video. Clinician and peer-led group participants reported the group setting, feeling that they were not alone, and the letter exercise as most valuable; the most common response of what was less valuable was "none." Many participants of the Internet version suggested increasing community support. Findings suggest the importance of considering the therapeutic value of group membership, and that online prevention programs could be enhanced by providing a mechanism for community support, such as an online forum. Results also inform selective prevention and suggest that screening potential participants to determine which delivery method best suits them should be considered. © 2016 Wiley Periodicals, Inc.

Social and individual influences on eating in pre-adolescents: The role of friends’ eating behaviours and individual anxiety and depression

Background: Friends are important role models for the formation of social norms and behaviour comparisons, particularly in children. This study examined the similarities between pre-adolescent children’s own eating behaviours with the eating behaviours of those in their friendship group. It also evaluated whether symptoms of anxiety and depression were related to eating behaviours in this age group. Methods: Three hundred and forty three children (mean age 8.75 years) completed questionnaires designed to measure dietary restraint, emotional eating and external eating, as well as general and social anxiety, and symptoms of depression. Children also provided details about their friendship groups. Results: Pre-adolescents’ dietary restraint was positively predicted by the dietary restraint of members of their friendship groups, and their individual levels of anxiety and depression. The levels of general anxiety exhibited by pre-adolescents predicted emotional and external eating behaviours. Younger children were significantly more likely to report higher levels of emotional and external eating than older children, and boys were more likely to report more external eating behaviours than girls. Conclusions: These results suggest that greater dieting behaviours in pre-adolescents are related to their friends’ reports of greater dieting behaviours. In contrast, greater levels of eating governed by emotions, and eating in response to external hunger cues, are related to greater symptoms of anxiety in pre-adolescent children. Such findings underline the importance of friends’ social influences on dieting behaviours in this age group and highlight the value of targeting healthy eating and eating disorder prevention interventions at pre-adolescents.

Media and cultural influences in african-american girls' eating disorder risk.

Objective. To investigate media and cultural influences in eating disorder development in African-American adolescent females. Method. Fifty-seven participants were recruited through churches and community organizations to complete a questionnaire. Results. Mainstream sociocultural identification was associated with more eating disorder behavior in African-American females; cultural ethnic identification was not significantly associated with eating disorder behavior in African-American females, mainstream sociocultural identification, cultural ethnic identification, and body dissatisfaction significantly predicted eating disorder behavior; and cultural ethnic identification was positively correlated with mainstream sociocultural identification. This study provides support for the importance of eating disorder prevention interventions that focus specifically on African-American girls.

Use of empirically supported interventions for psychopathology: Can the participatory approach move us beyond the research-to-practice gap?

Dissemination, or distribution, of empirically supported interventions (ESIs) for psychopathology remains a significant challenge. This paper reviews the principles of community-partnership research (CPR) and explores why CPR might improve distribution of psychological ESIs. Benefits of CPR include building trust, pooling resources and knowledge, and better serving a community by directly involving its members in the design and implementation of research. In addition, after establishing a community's trust using CPR, researchers are likely to be better positioned to partner with communities in the further distribution of ESIs via community networks. This paper reviews the case of dissonance-based eating disorder prevention interventions to provide an example of how CPR can facilitate the adoption and distribution of an ESI by a community, in this case, sororities. CPR also presents a number of challenges, however, because it is time consuming and does not always align with funding mechanisms and research designs used in randomized controlled trials. Further, CPR does not necessarily solve the challenge of training providers, though it may help with problem solving. Ultimately, we suggest that the benefits of CPR far outweigh the challenges, and hope that more researchers will adopt these practices so that more individuals can benefit from empirically supported psychological interventions.
