The Effects of Appearance-Based Comments and Non-Appearance-Based Evaluations on Body Dissatisfaction and Disordered Eating Urges: An Ecological Momentary Assessment Study

Ecological momentary assessment of weight-related stress predicting eating disorder and affective symptoms

Weight-related stress (e.g., experiencing weight stigmatization) is an important factor that contributes to engagement in maladaptive eating behaviors and increased risk for mood and anxiety disorders. Forty-nine adults that met the criteria for binge-eating disorder and/or food addiction completed baseline questionnaires and a 10-day ecological momentary assessment protocol during which they reported experiences of weight-related stress, binge-eating symptoms, dietary restraint, body satisfaction, and negative affect throughout the day. Generalized linear mixed models were used to examine associations between within- and between-subject weight-related stress and binge-eating symptoms, dietary restraint, body satisfaction, and negative affect. Weight-related stress was not associated with binge-eating symptoms; however, at the within-subjects level, experiencing weight-related stress was associated with lower body satisfaction (p = .008) and elevated dietary restraint and negative affect (ps < .001). At the between-subjects level, weight-related stress was associated with increased negative affect (p = .007). Among adults with binge-eating disorder and/or food addiction, weight-related stress may be a relevant social/intrapersonal experience that impacts individual's momentary affective well-being and restraint. Results suggest the need for public health interventions for reducing systemic societal weight-related stigmatization as well as use of individual intervention strategies focused on reframing negative thoughts associated with weight-related stress to reduce its emotional impact.

Momentary fluctuations in emotional intelligence and stress predict changes in disordered eating

Objective: Low emotional intelligence and symptoms of disordered eating are connected, however, whether daily fluctuations in emotional intelligence predict daily changes in disordered eating symptoms has not been examined, nor has stress been explored as a potential moderator of this relationship. Participants: Participants were undergraduate students (n = 100). Methods: Participants completed baseline questionnaires, then responded to random ecological momentary assessment prompts 3 times daily for 2 weeks. Results: Results indicated that when individuals had higher momentary emotional intelligence, they had lower disordered eating at the same time point (within subjects estimate = -0.30, p < .001) and following time point (within subjects estimate = -0.08, p = 0.03). Momentary stress moderated the relationship between baseline emotional intelligence and momentary disordered eating (b = -0.02, p < .01). Conclusions: Changes in emotional intelligence predict day-to-day changes in disordered eating, and stress moderates the connection between emotional intelligence and disordered eating.

Effects of videoconferencing use on momentary changes in disordered eating urges, body dissatisfaction, and mood

The coronavirus disease 2019 (COVID-19) pandemic led to a global surge in videoconferencing use for work/study-related reasons. Although these platforms heighten exposure to one's image, the implications of videoconferencing use on body image and eating concerns remain scantly examined. This study sought to investigate, in an Australian sample, whether videoconferencing for work/study-related reasons predicted increases in body dissatisfaction (BD), urge to engage in disordered eating (DE; restrictive eating, exercise, overeating/purging), and negative mood at the state level. Participants (N = 482, 78.8% women, Mage  = 20.5 years [SD = 5.3]) completed baseline demographic measures, accompanied by an ecological momentary assessment (EMA) of videoconferencing for work/study-related reasons, BD, DE urges, and negative mood six times a day for 7 days via a smartphone application. Most participants (n = 429; 89.0%) reported state-based videoconferencing use during the EMA phase. Consistent with expectations, state-based videoconferencing use was associated with an increase in state-level urges to engage in exercise. However, contrary to predictions, state-based videoconferencing use was linked to a decrease in state-level BD at the next assessment point and failed to predict negative mood and urges to engage in restrictive eating or overeating/purging at the state level. Given the simplified measure of videoconferencing use, the current research is considered preliminary and future replication and extension, using more nuanced measures, is warranted.

Tonight, I'm disordered eating: The effects of food delivery app use, loneliness, and mood on daily body dissatisfaction and disordered eating urges

With the recent proliferation of food delivery applications ('apps'; FDAs), accessing a meal is more convenient and immediate than ever. However, these apps may foster dysregulated eating behaviours, including maladaptive eating to cope with negative emotional states. Using ecological momentary assessment (EMA), the current study assessed whether FDA use at baseline predicted levels of EMA-assessed disordered eating urges and body dissatisfaction, whether negative mood and loneliness impacted disordered eating urges and body dissatisfaction at the state level, and whether the latter relationships were moderated by FDA usage frequency. Participants (N = 483; 78.7% women; 20.1% men; 1.2% other) completed a baseline questionnaire and were characterised as current FDA users (49.3%) or non-users (50.7%). Participants then completed a smartphone-facilitated investigation into their experiences of loneliness, negative mood, body dissatisfaction, and disordered eating urges, six times per day for 7-days. Across the entire sample, current FDA users at baseline reported greater EMA-assessed urges to overeat. At the state level, loneliness and negative mood predicted greater body dissatisfaction, with the latter also predicting greater urges for restrictive eating and overeating. Among current FDA users at baseline, at the state level, loneliness predicted greater body dissatisfaction, and negative mood predicted greater body dissatisfaction and urges for overeating. No moderating effects were observed for baseline FDA usage frequency. These results elucidate FDA use and daily experiences of loneliness and negative mood as factors elevating eating disorder (ED)-related risk. Further extensions of this research with nuanced measures of state FDA use are required.

The neural correlates of socio-cognitive factors and eating disorders in young people: A systematic review

BACKGROUND

Although the primary aetiology of Eating Disorders (ED) remains unknown, research suggests a complex interplay of biological, psychological, and cultural/environmental factors. This paper aims to systematically review the literature on neuroimaging studies that measure socio-cognitive factors, in the context of body dissatisfaction and EDs in young people. Specifically, our aim was to identify patterns in the findings linked to social media-type behaviours.

METHODS

The review was conducted in accordance with PRISMA guidelines using PubMed, Scopus, and Web of Science databases. 799 papers were identified in the database search and 38 studies were selected based on exclusion and inclusion criteria. Selected studies were assessed using the National Institute of Health study quality assessment tool.

RESULTS

Findings point to state-related impairments in inhibitory control and salient emotional processing. Anorexia Nervosa(AN) showed impaired set-shifting abilities, working memory and decision making, while altered activation in attention networks and associated difficulties with conflict resolution were seen for Bulimia Nervosa(BN) and Other Specified Feeding and Eating Disorders(OSFED). AN and BN also demonstrated altered sensitivity to food-related stimuli in striatal regions, suggesting aberrant top-down emotional-cognitive control. ED participants also show deficits in body representation, impaired control over social behaviours and altered integration of visual and body perception.

DISCUSSION

These findings support the notion that socio-cognitive dysfunctions in ED are underpinned by a distributed network of structural and functional brain changes which influence the way young people with ED interact with and respond to social media, and ultimately places at them at increased risk for body image disturbances.
