Dissonance-based eating disorder prevention among Brazilian young women: A randomized efficacy trial of the Body Project

Body image of university students: a systematic review of the characteristics of interventions

BACKGROUND

Body image is the mental representation of the body and can be influenced by cognitive, biological, behavioral, sociocultural, and environmental factors. University students often encounter challenges related to it.

OBJECTIVE

This systematic review examined interventions aimed at holistically developing a positive body image within this population.

METHODS

The PRISMA 2020 guidelines and the PICO method were employed to identify, select, assess, and synthesize studies. The consulted databases included Scopus, Web of Science, and PsycINFO, with inclusion criteria targeting body image interventions for university students aged 18 to 39. Study quality was evaluated using the QATSDD tool.

RESULTS

Twenty-one relevant studies were identified, primarily from the United States, mostly employing quantitative methods, with a focus on female participants. Various intervention strategies were utilized, including cognitive-behavioral approaches, media literacy, and physical/resistance training, with a growing use of technology like mobile applications. The majority of studies reported effective outcomes, such as reduced body dissatisfaction and increased self-esteem following interventions. Nevertheless, literature gaps were identified, such as the scarcity of formative interventions and limited use of qualitative approaches.

CONCLUSION

While technology in interventions offers promising opportunities, careful assessments and judicious selection of evaluation instruments are fundamental for reliable results. Future research should focus on addressing identified gaps, such as exploring more formative interventions and incorporating qualitative methodologies to provide a more comprehensive understanding of the effectiveness of body image interventions among university students.

A cognitive dissonance body image intervention 'Free Being Me' delivered by guide leaders to adolescent girl guides in India: A pilot and acceptability trial

This pilot study assessed the acceptability and pre-post intervention effects of a cognitive dissonance-based body image intervention, Free Being Me, delivered by Guide leaders to adolescent girls in India. Girls aged 11-14 years (Mage = 12.6, N = 117), who were members of the national scouting and guiding association of India, received the intervention across five weekly 1-hour group sessions. The primary outcome (body esteem) and secondary outcomes (self-esteem, internalisation of appearance ideals, negative and positive affect, and life disengagement) were measured pre-intervention and immediately post-intervention. The intervention was acceptable. Adolescent girls reported high levels of comfort (89%), enjoyment (90%), and perceived importance (92%) with suggestions for improvement including more interactive activities. Facilitator adherence and competence delivering Free Being Me was rated good. Significant within-groups pre-post intervention improvements in body esteem (Cohen's d = 0.28) and reductions in internalisation of appearance ideals (Cohen's d = 0.49) were identified. No changes to self-esteem, negative or positive affect, or life disengagement were observed. This study suggests that Free Being Me is acceptable for community-based delivery and Guide leader format with promising pre-post intervention effects. Going forward, a randomised controlled trial is necessary to make confident interpretations on the effectiveness of Free Being Me.

How effective are psychosocial interventions at improving body image and reducing disordered eating in adult men? A systematic review

Disordered eating and body image concerns significantly impact a growing number of men. This systematic review assessed the evidence of the effectiveness of psychosocial interventions to improve body image and eating pathology in men. Searches were conducted in December 2022 in 13 databases (PsycINFO, MEDLINE, CINAHL Plus, AMED, PubMed, Scopus, Cochrane, EMBASE, ASSIA, British Nursing Index, Wiley and OpenGrey). Studies that quantitatively evaluated psychosocial interventions and reported pre-post body image or disordered eating outcomes in men aged 18 years and over were eligible. Articles including boys, uncontrolled designs, or not in English were excluded. Findings were narratively synthesised and presented according to intervention approach. Quality was assessed using EPHPP. Eight studies including six RCTs were reviewed. Five were assessed as being moderate quality and three as weak. Evidence from moderate quality studies suggested that dissonance-based interventions showed promising improvements in body image and disordered eating for up to six months post-intervention in men with and without body dissatisfaction. Evidence for media literacy and psychoeducational interventions was limited. Findings were limited by heterogeneity in outcome measures and homogeneity of participants preventing generalisability. Robust research with longer follow-ups is needed to confirm effectiveness.

Comparing body image dissatisfaction between pregnant women and non-pregnant women: a systematic review and meta-analysis

Body image dissatisfaction refers to negative thoughts and feelings individuals have towards their own body appearance and this is thought to be affected by the physiological changes that occur during pregnancy. There are two main conflicting theories as to the effect pregnancy has on body image dissatisfaction: 1) Pregnancy related changes are in direct conflict with social ideas of female beauty (e.g. weight gain) and so increase body image dissatisfaction; 2) Due to changes in expectations of bodily appearance during pregnancy, women are liberated from social ideals at this time and thus body image dissatisfaction would decrease. This study aimed to assess these theories by synthesising the current literature. Six databases were searched, and 2,017 study abstracts were screened based on strict inclusion and exclusion criteria. Following screening and quality assessment by two blind reviewers, 17 studies (comprising 17 effect sizes) were subject to full review and meta-analysis following PRISMA guidelines. These studies included cross-sectional, longitudinal and retrospective designs. Results varied with some studies showing women to feel more positive about their body during pregnancy, others showing a more negative body experience and yet others showing no statistical difference. Overall the analysis showed no statistical difference in body image dissatisfaction between pregnant women and non-pregnant women (p = 0.39). Any changes that do occur are heterogeneous and likely to be largely dependent on the individual experience as well as moderator variables and other factors such as differences in methodology of research studies. Studies in this field of research would benefit from more explicit and complete reporting of data and key variables, in order to allow early intervention for women who display body image dissatisfaction in pregnancy.

A randomized controlled trial to evaluate the acceptability and effectiveness of two eating disorders prevention interventions: the HEIDI BP-HW project

BACKGROUND

Eating disorders (ED) are common in Switzerland, as in other Western countries, with a prevalence of any ED of 3.5%. However, no specific prevention intervention has been evaluated in the French-speaking part of the country. In this study, we assessed the acceptability and effectiveness of two well-validated eating disorders prevention interventions: the Body Project intervention (BP), based on cognitive dissonance techniques, and the Healthy Weight intervention (HW), based on the implementation of a healthy lifestyle.

METHODS

Forty female students, aged 18-28, with body dissatisfaction, were randomized into three arms: a BP group, an HW group, and a waiting-list control group (WLCG). The primary outcome measure was body dissatisfaction. Secondary outcomes were thin-ideal internalization, dietary restraint, negative affect, and ED psychopathology. Thirty-three participants completed the assessments before and after the one-month interventions or waiting period. A follow-up measurement was conducted one month after the interventions to assess the stability of the results.

RESULTS

Both interventions, delivered via a virtual web platform, were considered acceptable. The reduction in body dissatisfaction was greater in the BP group (r = 0.7; p < 0.01) or the HW group (r = 0.6; p < 0.01) than in the WLCG, with large effect sizes. Dietary restraint and shape concern were also significantly reduced in the BP group (r = 0.6 and r = 0.7, respectively; p < 0.01) and HW group (r = 0.5 and r = 0.5, respectively; p < 0.05) compared to the WLCG, with moderate to large effect sizes. The results obtained in each intervention group were stable at the one-month follow-up.

CONCLUSIONS

This study showed encouraging results in young women with body dissatisfaction, arguing in favor of the French adaptations of the BP and HW interventions. However, the feasibility of recruitment was difficult, partly due to the pandemic situation at the time of the study, and should be further considered to improve dissemination.

Eating disorders prevention programs in Latin American countries: A systematic review

OBJECTIVE

This systematic review evaluates and summarizes existing eating disorder (ED) prevention programs in Latin American countries.

METHODS

A systematic literature search was conducted using the Cochrane Controlled Trial Register, PubMed, and Virtual Health Library databases up to and including July 31, 2022. All ED prevention studies published in English, Spanish or Portuguese were eligible, regardless of the study design, sample characteristics, and type of prevention programs. The Cochrane Collaboration Risk of Bias criteria were used to evaluate the quality of the included studies.

RESULTS

Twenty-two studies were included. Most were pilot studies that were nonrandomized, had a high risk of bias, were from Mexico and Brazil, and employed selective interventions. Dissonance-based programs and social cognitive theory were the commonly used approaches in interventions, and most of them were tested in adolescent girls and women. Short follow-ups were used, varying from 1 to 6 months. Many found significant decreases after the intervention and/or at follow-up in ED/disordered eating risk behaviors/symptoms, negative affect, body-ideal internalization, and body image disturbances.

CONCLUSIONS

This review highlights promising efforts to prevent EDs among Latin American countries. Some barriers in conducting research include funding restrictions, laws that do not allow remuneration or compensation for participants, and high costs of training. Nonetheless, the outcomes of the programs developed and evaluated so far are positive enough to merit further work on ED prevention. Efforts for future researchers should recruit samples with diverse characteristics, use robust designs and data analysis techniques, and expand the accessibility of prevention programs.

PUBLIC SIGNIFICANCE STATEMENT

The development of effective eating disorder (ED) prevention programs that can be broadly implemented is a public health priority. Nevertheless, there is limited evidence regarding the characteristics of ED prevention programs and their efficacy among Latin American countries. In the present study, we reviewed existing ED prevention programs adopted in Latin America, described their characteristics and outcomes, noted the limitations of available programs, and discussed the implications of these findings for efforts to prevent the development of EDs in Latin America. The outcomes of the programs developed and evaluated so far are positive enough to merit the development and rigorous evaluation of future programs and their broad dissemination in Latin American countries.

Expert peer facilitation of the EVERYbody Project: A randomized-controlled evaluation of a diversity-focused, dissonance-based, universal body image program for college students

OBJECTIVE

A novel peer facilitation model was used to deliver a two session, dissonance-based, inclusive body image intervention that critically examines how internalized size-based oppression intersects with race, class, gender, sexuality, and ability.

METHOD

The EVERYbody Project was open to all college students and delivered by "expert" peer facilitators with body image and diversity experience and advanced facilitation skills. Recruitment was halted due to COVID-19; 90 students in the Northwest US (M age = 19.83 years, SD = 2.38; 80% female-identified, 13% male-identified, 7% gender expansive) were randomized to receive the EVERYbody Project or a video-based, low-dissonance comparison intervention.

RESULTS

Around half of students (56%) held one or more specific socially marginalized identity (26% with a racial or ethnic identity other than white and non-Hispanic, 39% with a sexual identity other than straight, 7% with a gender identity other than cisgender). The EVERYbody Project produced greater reductions in three outcomes associated with poor body image (internalized appearance norms, body dissatisfaction, and negative affect) compared to the video intervention through 3-month follow-up (ps < .003) with medium between group effects. Both conditions experienced small reductions in eating disorder psychopathology over time.

DISCUSSION

Expert peer facilitation may be a viable delivery model for inclusive, diversity-focused dissonance-based body image programs.

PUBLIC SIGNIFICANCE

This study explored a novel facilitation approach for a diversity-focused body image program for college students. A brief (4 h) dissonance-based program was open to all college students and delivered by "expert" diverse peer leaders who were screened for facilitation readiness. Body image and related outcomes were improved through 3-month follow-up relative to a comparison condition, suggesting that expert peer facilitation may be a viable option for delivering universal, inclusive body image programming.

Eating disorder psychopathology and negative affect in Iranian college students: a network analysis

BACKGROUND

ED psychopathology is becoming more prevalent in Iran. Negative affect has been found to be an important risk factor in eating disorder (ED) onset in research conducted in Western countries, and is also emerging as a potential vulnerability factor to ED psychopathology in Iran. Network theory offers a novel framework to understand the association between negative affect and ED psychopathology in Iran. The primary aim of the current study was to use network analysis to identify bridge symptoms (i.e., symptoms that activate or weaken symptoms in another cluster) across a negative affect and ED psychopathology network among Iranian college students. We also aimed to identify core symptoms (i.e., nodes that demonstrate the strongest connections to other nodes).

METHOD

Participants were Iranian college students (n = 637; 60.3% women) who completed the Farsi-eating disorder examination-questionnaire and Farsi-negative affect. We estimated a network of ED symptoms and negative affective states and identified bridge and central symptoms.

RESULTS

Hostility and shame emerged as central bridge symptoms across the negative affect and ED psychopathology clusters. The most central nodes were strong desire to lose weight, definite fear of losing control over eating, and binge eating episodes.

CONCLUSION

The negative affective states of hostility and shame may increase vulnerability to ED psychopathology among Iranian college students. Findings have important implications for ED prevention programs that should be examined in future research.

Prevention of eating disorders: 2021 in review

This review of 19 prevention-related publications in Eating Disorders during 2021 is framed by four models: (1) Mental Health Intervention Spectrum: health promotion → types of prevention → case identification/referral → treatment; (2) the prevention cycle: rationale and theory, shaped by critical reviews → clarifying risk and protective factors → program innovation and feasibility studies → efficacy and effectiveness research → program dissemination; (3) links between disordered eating (DE) and eating disorders (EDs); and (4) Kraemer and Jacobi's criteria for variable, causal risk factors (RFs). Twelve articles demonstrated the strengths and limitations of cross-sectional investigations of RFs for DE and EDs: five explored the role of trauma in activating genetic and psychological RFs (e.g., anxiety and experiential avoidance), while five suggest other variables meriting further evaluation: ergogenic supplement use, "feeling fat," internalized weight bias, food insecurity, and compulsive exercising. One article presents a pilot program that reduced risk factors in a high-risk group: professional ballerinas. Implications of the absence of efficacy, effectiveness, dissemination, and advocacy studies, along with the need to develop tailored programs for various high-risk groups, are discussed.

New developments in cognitive-behavioural therapy for eating disorders (CBT-ED)

PURPOSE OF REVIEW

This review summarizes recent developments in cognitive-behavioural therapy for eating disorders (CBT-ED). More specifically, the past five years were covered, with the latest UK and Dutch guidelines for eating disorders as a starting benchmark, and with special consideration of the past 18 months.

RECENT FINDINGS

The new research can be divided into findings that have: (1) reinforced our existing understanding of CBT-ED's models and impact; (2) advanced our understanding and the utility of CBT-ED, including its application for the 'new' disorder Avoidant/Restrictive Food Intake Disorder (ARFID); (3) suggested new directions, which require further exploration in clinical and research terms. These include learning from the circumstances of the COVID-19 pandemic.

SUMMARY

CBT-ED has developed substantially in the past 5 years, with consolidation of its existing evidence base, further support for real-life implementation, extension of methods used, and the development of new approaches for working with younger people - particularly in the form of treatments for ARFID. Over the past 18 months, even more promising changes in delivery occurred in response to the COVID19 pandemic, showing that we can adapt our methods in order to work effectively via remote means. Challenges remain regarding poor outcomes for anorexia nervosa.
