A three-arm randomised controlled trial of a telehealth intervention targeting improvement in addictive eating for Australian adults (the TRACE program).

There is a substantial research base for addictive eating with development of interventions. The current 3-arm RCT aimed to investigate the efficacy of the TRACE (Targeted Research for Addictive and Compulsive Eating) program to decrease addictive eating symptoms and improve mental health. Participants (18-85 yrs) endorsing ≥3 addictive eating symptoms were randomly allocated to 1) active intervention, 2) passive intervention, or 3) control group. Primary outcome was change in addictive eating symptoms 3-months post-baseline measured by the Yale Food Addiction Scale. Depression, anxiety and stress were also assessed. A total of 175 individuals were randomised. Using Linear Mixed Models, from baseline to 3-months, there was significant improvement in symptom scores in all groups with mean decrease of 4.7 (95% CI: -5.8, -3.6; p < 0.001), 3.8 (95% CI: -5.2, -2.4; p < 0.001) and 1.5 (95% CI: -2.6, -0.4; p = 0.01) respectively. Compared with the control group, participants in the active intervention were five times more likely to achieve a clinically significant change in symptom scores. There was a significant reduction in depression scores in the active and passive intervention groups, but not control group [-2.9 (95% CI: -4.5, -1.3); -2.3 (95% CI: -4.3, -0.3); 0.5 (95% CI: -1.1, 2.1), respectively]; a significant reduction in stress scores within the active group, but not passive intervention or control groups [-1.3 (95% CI: -2.2, -0.5); -1.0 (95% CI: -2.1, 0.1); 0.4 (95% CI: -0.5, 1.2), respectively]; and the reduction in anxiety scores over time was similar for all groups. A dietitian-led telehealth intervention for addictive eating in adults was more effective than a passive or control condition in reducing addictive eating scores from baseline to 6 months.

Enhancing understanding of social media literacy to better inform prevention of body image and eating disorders.

Research has revealed an important role for appearance-focused, and in particular photo-based, social media in the development of body image and eating pathology. Social media literacy is a multifaceted construct involving purposeful selection and exposure to social media content and use of protective filtering (deliberately screening and interpreting information in a protective manner), as well as implementing critical skills related to understanding the unrealistic nature of social media content, limiting appearance comparisons with images, and contributing to social media (comments and images) in ways that limit the pursuit of appearance ideals. Previous work has provided partial support for these facets as related to lower levels of body image and eating concerns. However, additional conceptual and measurement work is needed to advance understanding of this protective role and how to foster social media literacy. Although data are scarce, targeting social media literacy in prevention and intervention programs may also be valuable. In this perspective piece, key features that we identify as priorities for future prevention and intervention efforts include developing interventions that target the implementation of social media skills beyond their acquisition. In addition, leveraging social media user generated content for prevention purposes would likely be useful, as would embedding micro-skill delivery within platforms.

The impact of climate change on eating disorders: An urgent call for research.

Climate change affects many of the documented risk factors for eating disorders (EDs) through direct and indirect pathways, yet to date the research in this area is nonexistent. Our aim is to identify the specific mechanisms through which climate change might be associated with increased risk for EDs, an exacerbation in symptoms, or poor clinical outcomes; highlight limited empirical data addressing these issues; and propose directions for a research program in this important area. Pathways for the impact of climate change on eating disorders and related data were reviewed. Four main pathways for the effects of climate change on EDs were identified including (1) decreased food access and security; (2) changes in mean temperature; (3) concerns related to food safety and eco-anxiety; and (4) indirect pathways through trauma, adversity, and increased mental health concerns. Except for the relationship between increased food insecurity and EDs, these pathways remain largely uninvestigated. Numerous factors may be implicated in the relationship between climate change and EDs. Future work in this area is imperative and should be conducted through a social justice lens with particular attention paid to the global areas most impacted by climate change and related vulnerabilities. Climate change will likely have adverse impacts on individuals with eating disorders and increase the risk for eating disorders. This paper reviews the different ways in which climate change may have these effects and calls for researchers to pay attention to this important area.

The need for future research into the assessment and monitoring of eating disorder risk in the context of obesity treatment.

In adolescents and adults, the co-occurrence of eating disorders and overweight or obesity is continuing to increase, and the prevalence of eating disorders is higher in people with higher weight compared to those with lower weight. People with an eating disorder with higher weight are more likely to present for weight loss than for eating disorder treatment. However, there are no clinical practice guidelines on how to screen, assess, and monitor eating disorder risk in the context of obesity treatment. In this article, we first summarize current challenges and knowledge gaps related to the identification and assessment of eating disorder risk and symptoms in people with higher weight seeking obesity treatment. Specifically, we discuss considerations relating to the validation of current self-report measures, dietary restraint, body dissatisfaction, binge eating, and how change in eating disorder risk can be measured in this setting. Second, we propose avenues for further research to guide the development and implementation of clinical and research protocols for the identification and assessment of eating disorders in people with higher weight in the context of obesity treatment. PUBLIC SIGNIFICANCE: The number of people with both eating disorders and higher weight is increasing. Currently, there is little guidance for clinicians and researchers about how to identify and monitor risk of eating disorders in people with higher weight. We present limitations of current research and suggest future avenues for research to enhance care for people living with higher weight with eating disorders.

Eating Disorders In weight-related Therapy (EDIT) Collaboration: rationale and study design.

The cornerstone of obesity treatment is behavioural weight management, resulting in significant improvements in cardio-metabolic and psychosocial health. However, there is ongoing concern that dietary interventions used for weight management may precipitate the development of eating disorders. Systematic reviews demonstrate that, while for most participants medically supervised obesity treatment improves risk scores related to eating disorders, a subset of people who undergo obesity treatment may have poor outcomes for eating disorders. This review summarises the background and rationale for the formation of the Eating Disorders In weight-related Therapy (EDIT) Collaboration. The EDIT Collaboration will explore the complex risk factor interactions that precede changes to eating disorder risk following weight management. In this review, we also outline the programme of work and design of studies for the EDIT Collaboration, including expected knowledge gains. The EDIT studies explore risk factors and the interactions between them using individual-level data from international weight management trials. Combining all available data on eating disorder risk from weight management trials will allow sufficient sample size to interrogate our hypothesis: that individuals undertaking weight management interventions will vary in their eating disorder risk profile, on the basis of personal characteristics and intervention strategies available to them. The collaboration includes the integration of health consumers in project development and translation. An important knowledge gain from this project is a comprehensive understanding of the impact of weight management interventions on eating disorder risk.

Examination of the temporal sequence between social media use and well-being in a representative sample of adults.

Given insufficient prospective evidence for relationships between social media use and well-being among adults, the present study examined the temporal sequence between social media use and psychological distress and life satisfaction, and explored age and gender differences. A representative sample of adults (N = 7331; 62.4% women; Mage = 51.94; SD = 13.48; 15-94 years) were surveyed annually across four waves. Cross-lagged panel models demonstrated bidirectional relationships between social media use and well-being. Higher psychological distress and lower life satisfaction predicted higher social media use more strongly than the reverse direction, with effects particularly pronounced for the impact of psychological distress. Although the patterns of findings were relatively consistent across age and gender, results suggested that women and middle- and older-aged adults experience detrimental effects of social media use on well-being, which may drive subsequent increased use of social media. The bidirectional relationships suggest that adults who experience psychological distress or lower life satisfaction may seek to use social media as a way to alleviate poor well-being. However, paradoxically, this maladaptive coping mechanism appears to drive increased social media use which in turn can exacerbate poor well-being. Clinicians should be aware of these bidirectional relationships and work with clients towards replacing ineffective strategies with more helpful coping approaches. As this study used a simplistic measure of social media use, future research should address this limitation and explore nuanced relationships afforded by assessing specific social media activities or exposure to certain types of content.

Identifying eating disorders in adolescents and adults with overweight or obesity: A systematic review of screening questionnaires.

OBJECTIVE: This review aimed to examine the validity of self-report screening questionnaires for identifying eating disorder (ED) risk in adults and adolescents with overweight/obesity. METHOD: Five databases were searched from inception to September 2020 for studies assessing validation of self-report ED screening questionnaires against diagnostic interviews in adolescents and adults with overweight/obesity. The review was registered with PROSPERO (https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=220013). RESULTS: Twenty-seven papers examining 15 questionnaires were included. Most studies validated questionnaires for adults (22 of 27 studies), and most questionnaires (12 of 15) screened for binge eating or binge-eating disorder (BED). The Eating Disorder Examination Questionnaire (sensitivity = .16-.88, specificity = .62-1.0) and Questionnaire on Eating and Weight Patterns (sensitivity = .07-1.0, specificity = .0-1.0) were most frequently validated (six studies each). Five studies of three questionnaires were in adolescents, with the Adolescent Binge-Eating Disorder Questionnaire having highest sensitivity (1.0) but lower specificity (.27). Questionnaires designed to screen for BED generally had higher diagnostic accuracy than those screening for EDs in general. DISCUSSION: Questionnaires have been well validated to identify BED in adults with overweight/obesity. Validated screening tools to identify other EDs in adults and any ED in adolescents with overweight/obesity are lacking. Thus, clinical assessment should inform the identification of patients with co-morbid EDs and overweight/obesity. PUBLIC SIGNIFICANCE: Individuals with overweight/obesity are at increased risk of EDs. This review highlights literature gaps regarding screening for ED risk in this vulnerable group. This work presents possibilities for improving care of individuals with overweight/obesity by reinventing ED screening tools to be better suited to diverse populations.

OBJETIVO: Esta revisión tuvo como objetivo examinar la validez de los cuestionarios de detección de autorreporte para identificar el riesgo de trastorno de la conducta alimentaria (TCA) en adultos y adolescentes con sobrepeso/obesidad. MÉTODO: Se realizaron búsquedas en cinco bases de datos desde su inicio hasta septiembre de 2020 para obtener estudios que evaluaran la validación de los cuestionarios de autorreporte de detección de TCA frente a entrevistas diagnósticas en adolescentes y adultos con sobrepeso/obesidad. La revisión se registró en PROSPERO (https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=220013). RESULTADOS: Se incluyeron veintisiete artículos que examinaron 15 cuestionarios. La mayoría de los estudios validaron cuestionarios para adultos (22 de 27 estudios) y la mayoría de los cuestionarios (12 de 15) detectaban atracones o trastorno por atracón (BED, en sus siglas en inglés). El Cuestionario de Examen de Trastornos alimentarios (Eating Disorder Examination Questionnaire) (sensibilidad = 0.16-0.88, especificidad = 0.62-1.0) y el Cuestionario sobre patrones de alimentación y peso (Questionnaire on Eating and Weight Patterns) (sensibilidad = 0.07-1.0, especificidad = 0.0-1.0) se validaron con mayor frecuencia (seis estudios cada uno). Cinco estudios de tres cuestionarios fueron en adolescentes, y el Cuestionario de Trastorno por Atracón en Adolescentes (Adolescent Binge-eating Disorder Questionnaire) tuvo la mayor sensibilidad (1,0) pero una menor especificidad (0,27). Los cuestionarios diseñados para detectar BED generalmente tuvieron una mayor precisión diagnóstica que los que detectaron TCA en general. DISCUSIÓN: Los cuestionarios han sido bien validados para identificar BED en adultos con sobrepeso/obesidad. Faltan herramientas de detección validadas para identificar otros TCA en adultos y cualquier tipo de trastorno de la conducta alimentaria en adolescentes con sobrepeso / obesidad. Por lo tanto, la evaluación clínica debe informar la identificación de pacientes con comorbilidad de TCA y sobrepeso/obesidad.

Clinically significant body dissatisfaction: prevalence and association with depressive symptoms in adolescent boys and girls.

Body dissatisfaction is distressing and a risk factor for adverse consequences including eating disorders. However, data pertaining to the prevalence of body dissatisfaction in adolescence, a key period for its emergence, are lacking. This is a substantial barrier to tailored assessment and early intervention. This study addresses this gap and provides the prevalence of body dissatisfaction and associations with depressive symptoms and body change strategies. Adolescent boys (n = 367; Mage = 12.8, SD = 0.7) and girls (n = 368; Mage = 12.7, SD = 0.7) completed measures of body dissatisfaction and depressive symptoms with established cut-off levels. They also completed measures of dietary restraint and strategies to increase muscle size. Of boys and girls, 37.9% and 20.7%, respectively experienced moderate, and 6.8% and 19.6% experienced clinically significant body dissatisfaction, with higher rates among girls than boys and among adolescents aged 13 and 14 than aged 12. More than one-quarter of boys (26.70%) and one-third of girls (33.15%) reported subthreshold depressive symptoms or possible, probable or major depressive episodes. Girls revealed a higher prevalence of possible-, probable-, or major depressive episode than boys. Relative to those with no or low body dissatisfaction, adolescents with clinically significant body dissatisfaction were 24 times more likely to also report possible-, probable-, or major depressive episodes. Among boys and girls, clinically significant body dissatisfaction was associated with higher levels of dietary restraint and engagement in strategies to increase muscle size. Greater attention to identification and early intervention for body dissatisfaction is needed, especially for girls.

Disordered eating, body image concerns, and weight control behaviors in primary school aged children: A systematic review and meta-analysis of universal-selective prevention interventions.

OBJECTIVE: Body image concerns and extreme weight control behaviors frequently develop in childhood indicating an important age group for the implementation of universal-selective prevention approaches. This systematic review aimed to evaluate the effect of universal-selective prevention interventions addressing disordered eating, body image concerns, and/or extreme weight control behaviors in children aged 6-12 years. METHOD: Nine databases were searched up to April 2021. Studies were included if they delivered a universal-selective prevention intervention to children aged 6-12 years and reported outcomes relating to body image, disordered eating, or weight control behaviors. The review was conducted in line with the PRISMA Guidelines. RESULTS: A total of 42 articles describing 39 studies included in the review, with most (n = 24; 57%) classified as neutral quality. Thirty studies implemented an eating disorder specific universal-selective program and nine implemented lifestyle interventions plus content to address disordered eating risk factors. Meta-analysis (n = 16 studies) revealed an improvement in body image-related outcomes across all studies (standardized mean difference [SMD] 0.26 [95%CI 0.01, 0.51]); with a high level of heterogeneity (Î2 = 89.9%; p < .01). Meta-analysis according to gender revealed a general improvement in body image-related outcomes for girls (SMD 0.40 [95%CI 0.07, 0.73]), but not boys (SMD 0.23 [95%CI -0.24, 0.70]). DISCUSSION: By investigating child, parental and teaching interventions and including outcomes such as weight control and disordered eating behaviors, a trend toward a reduction in eating disorder risk factors was observed, particularly body image-related outomes in girls. Future directions include embedded disordered eating prevention materials within existing lifestyle interventions and inclusion of more diverse samples.

OBJETIVO: Las preocupaciones sobre la imagen corporal y los comportamientos de control de peso extremo se desarrollan con frecuencia en la infancia, lo que indica un grupo de edad importante para la implementación de enfoques de prevención universal-selectiva. Esta revisión sistemática tuvo como objetivo evaluar el efecto de las intervenciones de prevención universal-selectivas que abordan la alimentación disfuncional, los problemas de imagen corporal y/o los comportamientos extremos de control de peso en niños de 6 a 12 años de edad. MÉTODO: Se realizaron búsquedas en nueve bases de datos hasta abril 2021. Se incluyeron estudios que habían incluido una intervención de prevención universal-selectiva en niños de 6 a 12 años de edad e informaron resultados relacionados con la imagen corporal, la alimentación disfuncional o los comportamientos de control de peso. El examen se llevó a cabo de conformidad con los lineamientos PRISMA. RESULTADOS: Un total de 42 artículos que describieron 39 estudios incluidos en la revisión, con la mayoría (n = 24; 57%) de calidad neutra. Treinta estudios implementaron un programa selectivo universal específico de trastornos de la conducta alimentaria y nueve implementaron intervenciones de estilo de vida más contenido para abordar la alimentación disfuncional. El metanálisis (n = 16 estudios) reveló una mejoría en los resultados relacionados con la imagen corporal en todos los estudios (DME 0,26 [IC95%: 0,00 a 0,53]); con un alto nivel de heterogeneidad (Î2 = 91,1%; p < 0,01). El metanálisis según el sexo reveló una mejora general en los resultados relacionados con la imagen corporal para las niñas (DME 0,40 [IC95%: 0,07 a 0,73]), pero no para los niños (DME 0,23 [IC95%: −0,24 a 0,70]). DISCUSIÓN: Al investigar las intervenciones tanto de los padres como de la enseñanza e incluir resultados como el control de peso y las conductas alimentarias de riesgo, se observó una tendencia hacia una reducción de los factores de riesgo de los trastornos de la conducta alimentaria. En concreto, mejoras en las variables relacionadas con la imagen corporal, especialmente en las niñas. Las direcciones futuras incluyen materiales de prevención de la alimentación disfuncional incorporados dentro de las intervenciones de estilo de vida existentes y la inclusión de muestras más diversas. PALABRAS CLAVE: Niños, trastornos de la conducta alimentaria y de la alimentación, alimentación disfuncional, prevención, imagen corporal, revisión sistemática, metanálisis.

Motivations for Social Media Use: Associations with Social Media Engagement and Body Satisfaction and Well-Being among Adolescents.

Adolescents are spending considerable time on social media, yet it is unclear whether motivations for social media use drive different forms of social media engagement, and their relationships with body satisfaction and well-being. This study tested a proposed model of the relationships between motivations for social media use, types of social media engagement and body satisfaction and well-being. Responses to an online survey from 1432 Australian adolescents (Mage = 13.45 years, SD = 1.14, range 11-17; 55.4% boys) were collected. Structural equational modelling indicates excellent model fit. Specifically, motivations for social media use (information sharing, passing time, escapism, social interaction, social capital and appearance feedback) were associated with engagement (intensity, photo-based use, active use, passive use and liking use) and revealed mixed associations with body satisfaction and well-being. The findings support the importance of considering motivations for social media use in future research.

Maternal influences on body image and eating concerns among 7- and 8-year-old boys and girls: Cross-sectional and prospective relations.

OBJECTIVE: Little is known regarding maternal influences on the body image and eating concerns of young children. The current study aimed to examine the cross-sectional and longitudinal relationships between maternal comments about their child's weight and shape and eating, and mothers' own body dissatisfaction and disordered eating on one hand, and their children's body esteem and disordered eating behaviors on the other. METHOD: Children, n = 244 of the fifth wave, aged 7 years (58% female), and n = 194 of the sixth wave, aged 8 years (57% female), of the longitudinal Children's Body Image Development Study, in Melbourne, Australia were included. Mothers completed measures of body dissatisfaction, dietary restraint, and comments and concerns regarding their children's weight and eating behaviors. They also reported on their children's disordered eating behaviors. Children's body esteem was assessed through a child interview. RESULTS: Findings revealed cross-sectional and prospective bivariate relationships between maternal comments and disordered eating behaviors among both boys and girls. Similar patterns of relationships emerged between maternal body dissatisfaction and lower child body esteem. CONCLUSION: Findings highlight the importance of conducting prevention within the family environment from a young age, and targeting both direct communication as well as parental body image and eating behaviors.

Early mother-child dyadic pathways to childhood obesity risk: A conceptual model.

Understanding the emotional quality of the mother-child dyadic relationship and parent-child feeding interactions may further clarify early developmental pathways to eating behaviours and obesity risk. The quality of parent-child relationships fosters all aspects of child development but has not yet been extensively examined in relation to childhood weight gain. The aim of this paper is to propose a conceptual model, which outlines early mother-child dyadic pathways linking parent-child feeding interactions to child body mass index, where parent-child relationships have a central role. It maps out individual and dyadic mother-child factors (i.e., attachment, child temperament and maternal mental health) that influence the nature and quality of parent-child feeding interactions from infancy to toddlerhood. Our model bridges the gap between research fields by bringing together key maternal and child factors implicated in child development. Understanding early parent-child feeding interactional patterns and their influence on child self-regulation and eating behaviours may be relevant to multidisciplinary approaches toward preventing childhood obesity. High quality quantitative and observational data capturing meaningful parent, child and dyadic level interactions around food contexts, attachment security, maternal mental health, child temperament and self-regulation will help to inform new, aetiologically important, targets for preventative intervention.

A systematic review of outcomes following residential treatment for eating disorders.

OBJECTIVE: Residential centres for the treatment of eating disorders are becoming increasingly common, yet data following residential care are scarce. We reviewed outcomes of residential treatment for eating disorders across all diagnoses, age groups and genders. A secondary goal was to identify treatment elements and patient characteristics that predicted a greater response to treatment. METHOD: Peer-reviewed studies published in the last 20 years were identified through a systematic search of the electronic databases PubMed and Cochrane Library. RESULTS: Nineteen open-label studies reporting changes between admission and discharge were included in this review. Most took an eclectic approach to treatment, integrating elements from several different techniques without a unifying theoretical framework. All studies reported improvements in most outcomes at discharge, including changes in eating disorders psychopathology, weight, depression, anxiety and quality of life. Eight studies reported outcomes at some interval after discharge, with largely positive outcomes. CONCLUSIONS: While residential care was associated with consistently positive outcomes, the variability in program characteristics and poor quality of research designs prevent firm conclusions from being drawn about their efficacy. Future research should include controlled studies that evaluate specific theoretical approaches and program elements, include long-term follow-up, and compare residential care to other treatment settings.

A Biopsychosocial Model of Social Media Use and Body Image Concerns, Disordered Eating, and Muscle-Building Behaviors among Adolescent Girls and Boys.

Social media use is associated with body image concerns, disordered eating and body change behaviors in adolescents. This study aimed to examine these relationships within a biopsychosocial framework and test an integrated model. A sample of 681 adolescents (49% female), mean age = 12.76 years (SD = 0.74), completed a questionnaire assessing social media use, depression, self-esteem, body mass index, social media and muscular ideal internalization, appearance comparison, body dissatisfaction, disordered eating, and muscle-building behaviors. Path analysis was used to test the hypothetical model, which after modification revealed good fit to the data, although gender differences emerged. The findings suggest that biopsychosocial frameworks are useful for conceptualizing relationships between social media use and body image, eating, and muscle building outcomes.

Confident body, confident child: Evaluation of a universal parenting resource promoting healthy body image and eating patterns in early childhood-6- and 12-month outcomes from a randomized controlled trial.

OBJECTIVE: To evaluate Confident Body, Confident Child (CBCC), a universal parenting resource designed to promote positive body image and healthy eating patterns in children aged 2-6 years, at 6- and 12-months follow-up. METHOD: A four-arm randomized controlled trial with 345 parents was conducted. Group (A) received the CBCC resource pack + workshop, (B) received the CBCC resource pack only, (C) received a nutrition booklet and (D) received no interventions until all questionnaires were completed (i.e., waitlist control). Measures of parenting variables relevant to child body image and eating patterns, and parent-report of child weight, were administered at baseline, 6-weeks post-intervention (results reported previously), and 6- and 12-months follow-up. RESULTS: Mixed effects modeling comparing group averages over time revealed that significant group differences on measures of knowledge, parenting intentions and the parental feeding practice of weight restriction were still present at 12-months follow-up, though the remaining measures showed no significant differences between groups over time. The two CBCC groups reported more positive and less negative outcomes than the nutrition booklet active control. DISCUSSION: The CBCC program achieved sustained improvements in some parenting variables at 12-months, suggesting its value as an effective parenting intervention. Changes to the intervention design, such as the addition of a follow-up parent workshop, however, would likely increase its efficacy.

Comparing internalization of appearance ideals and appearance-related pressures among women from the United States, Italy, England, and Australia.

Researchers have observed variation in levels of body image disturbance and eating pathology among women from different Western countries. Examination of cross-cultural differences in the established risk factors (i.e., thin-ideal internalization, muscular-ideal internalization, and appearance pressures from family, peers, and media) for negative outcomes may help to elucidate the prominence of specific risk factors within a given Western society and guide associated interventions. Women from the United States (US), Italy, England, and Australia completed the Sociocultural Attitudes Towards Appearance Questionnaire-4 (SATAQ-4). Analysis of covariance controlling for age and BMI indicated significant cross-country differences for all SATAQ-4 subscales. Results typically indicated higher levels of appearance-ideal internalization and appearance pressures in the US and lower levels in Italy; however, associated effect sizes were generally small. A medium effect of country was observed for peer-appearance pressures, which were highest in the US compared with all other countries. Repeated-measures analysis of variance and paired samples t tests conducted within each country identified thin-ideal internalization and media appearance pressures as the predominant risk factors for all four countries. Overall, findings suggest more cross-country similarities than differences, and highlight the importance of delivering interventions to address thin-ideal internalization and media appearance pressures among women from Western backgrounds.Level of evidence Descriptive study, Level V.

Risk and resiliency factors related to body dissatisfaction and disordered eating: The identity disruption model.

OBJECTIVE: The current study examined a theoretical model (the identity disruption model) linking negative early life experiences to body dissatisfaction and disordered eating via self-concept clarity and sociocultural factors (internalization of beauty ideals and appearance comparison tendencies). METHOD: 1,023 participants (52% women) completed a series of questionnaires online, including measures of negative early life experiences and childhood abuse, self-concept clarity, internalization of beauty ideals, appearance comparison tendencies, sociocultural pressure to improve one's appearance, body dissatisfaction, and disordered eating. RESULTS: Structural equation modeling indicated that self-reported early adversity was associated with lower self-concept clarity, which in turn was associated with greater internalization of beauty ideals and more frequent appearance comparisons. Internalization and appearance comparisons were associated with body image concerns, which in turn were associated with disordered eating and exercise behaviors. There were few sex differences in these paths. DISCUSSION: These findings provide initial conceptual support for the identity disruption model and extend previous models of body dissatisfaction and disordered eating to include processes that occur earlier in life. This model opens up the possibility for new interventions that are targeted toward those who are most vulnerable to developing body dissatisfaction and disordered eating.

Achieving body confidence for young children: Development and pilot study of a universal teacher-led body image and weight stigma program for early primary school children.

Negative body image attitudes develop in early childhood and there is a need for school-based resources during the early school years, but no teacher-delivered curriculum-based resources exist to mitigate these attitudes in young children. Achieving Body Confidence for Young Children (ABC-4-YC), a universal body dissatisfaction and weight stigma prevention program, was developed and then delivered in a pilot study. Fifty-one 5- to 8-year-old children completed pre- and post-intervention interviews assessing body image attitudes, and seven teachers provided feedback. Significant improvement in body esteem and positive teacher feedback were found. The results provide preliminary support for ABC-4-YC to improve children's body image attitudes, but extensive evaluation is needed.

A pilot evaluation of a social media literacy intervention to reduce risk factors for eating disorders.

OBJECTIVE: This pilot study investigated the effectiveness of a social media literacy intervention for adolescent girls on risk factors for eating disorders. METHOD: A quasi-experimental pre- to post-test design comparing intervention and control conditions was used. Participants were 101 adolescent girls (Mage = 13.13, SD = 0.33) who were allocated to receive three social media literacy intervention lessons (n = 64) or to receive classes as usual (n = 37). Self-report assessments of eating disorder risk factors were completed one week prior to, and one week following the intervention. RESULTS: Significant group by time interaction effects revealed improvements in the intervention condition relative to the control condition for body image (body esteem-weight; d = .19), disordered eating (dietary restraint; d = .26) and media literacy (realism scepticism; d = .32). DISCUSSION: The outcomes of this pilot study suggest that social media literacy is a potentially useful approach for prevention of risk for eating disorders in adolescent girls in the current social media environment of heightened vulnerability. Replication of this research with larger, randomized controlled trials, and longer follow-up is needed.

Do universal media literacy programs have an effect on weight and shape concern by influencing media internalization?

The current study examined whether media internalization, found to mediate the relationship between selected prevention programs and outcomes, mediated the impact of two universal prevention programs that targeted risk factors for eating disorders and obesity, namely weight concern, and shape concern. Students randomized to a media literacy (Media Smart) program (N = 269, 65% females, mean age 12.97 years) and a healthy lifestyle (Life Smart) program (N = 347, 69% females, mean age 13.07 years) were included in the analyses. There were four waves of data (baseline, end of intervention, 6- and 12-month follow-up). Latent growth curve modeling was used to explore whether group assignment influenced levels of media internalization, and whether that in turn influenced change over time of our two outcome variables. Being randomly allocated to Media Smart as opposed to Life Smart resulted in less growth of both outcome variables through the influence on decreasing levels of media internalization. Findings provided support for the suggestion that media literacy programs exert an impact on outcomes related to eating disorder risk through changes to media internalization. Future research should examine whether these mechanisms of change differ between girls and boys.
