Trait body image flexibility as a predictor of body image states in everyday life of young Australian women

Gay Dating Apps Usage, Body Dissatisfaction, and Disordered Eating in Chinese Young Gay Men

There is a paucity of research on the links between gay dating apps usage and body dissatisfaction and disordered eating, especially for muscularity dissatisfaction and muscularity-oriented disordered eating in non-Western contexts. Thus, this study aimed to evaluate the associations between gay dating apps usage, body image inflexibility, body dissatisfaction, and disordered eating with the inclusion of both body fat and muscularity dissatisfaction and both thinness-and muscularity-oriented disordered eating in a sample of Chinese young gay men. A total of 247 Chinese young gay men (mean age: 21.92 ± 2.74 years) were recruited. Gay dating apps usage, body fat dissatisfaction, muscularity dissatisfaction, body image inflexibility, and thinness-and muscularity-oriented disordered eating were evaluated. Pearson correlation and mediation analyses were conducted. Gay dating apps usage was positively correlated with body fat dissatisfaction (r = .20, p = .002), muscularity dissatisfaction (r = .17, p = .006), thinness-oriented disordered eating (r = .21, p < .001), and muscularity-oriented disordered eating (r = .29, p < .001), and these relationships could be mediated by body image inflexibility. Findings support technologically-informed prevention and intervention strategies for eating and body image disturbances in gay men in the Chinese context.

The distinct affect regulation functions of body image flexibility and inflexibility: A prospective study in adolescents and emerging adults

Body image flexibility and inflexibility are alternative ways of responding to body image threats. Affect regulation offers a framework for understanding how these responses impact health outcomes; however, research in young people is limited. This prospective study tested two potential affect regulation functions in adolescents and emerging adults (N = 351, 66.7% female) via online surveys completed five months apart. Specifically, body image flexibility and inflexibility were tested as (a) direct predictors of adaptive (body appreciation, intuitive eating) and maladaptive (muscle-building strategies, disordered eating) outcomes, and (b) moderators of the indirect effect of a social comparison threat via body appreciation. Results from hierarchical linear and conditional process models showed that body image flexibility and inflexibility served distinct affect regulation functions. Whereas body image inflexibility directly predicted adaptive and maladaptive body- and eating-related outcomes, body image flexibility protected against the negative effects of social comparison on intuitive eating via body appreciation. Findings suggest that adolescents and emerging adults could benefit from learning body image flexibility skills and reducing inflexibility to promote positive body image and prevent body- and eating-related disturbances. Future research should investigate how body image flexibility and inflexibility relate to other established threats and outcomes in diverse demographic groups.

Reciprocal longitudinal associations between positive body image and wellbeing among early-adult women

This longitudinal study examined the prospective associations between body appreciation and wellbeing (i.e., self-esteem, depression, and emotional wellbeing) as well as body image flexibility and wellbeing among 490 women between 18-35 years of age (M = 28.63; SD = 4.27) residing in the United States. Women were contacted in three waves, each two months apart, and completed measures relating to each construct online. As a prerequisite of longitudinal analyses, this study found evidence of configural, metric, scalar, and strict invariance over time for each relevant measure. Cross-lagged panel modeling evidenced bidirectional associations between body appreciation and self-esteem between all waves and unidirectional associations between body appreciation and subsequent depression (negative) and body appreciation and subsequent emotional wellbeing (positive). Results showed bidirectional associations between body image flexibility, self-esteem, depression, and emotional wellbeing, although these bidirectional associations never occurred during the same interval between waves. This study evidences that higher body appreciation and body image flexibility are prospectively associated with increases in self-esteem, emotional wellbeing and decreases in depression, and also shows scenarios where the inverse associations also hold true. We also describe how this study complements existing cross-sectional research and the need to examine associations among more diverse participant groups.

Testing for longitudinal bidirectional associations between self-compassion, self-criticism, and positive body image components

Previous cross-sectional studies have reported associations between self-compassion, self-criticism, and positive body image, yet prospective studies establishing the temporal order of these relationships are missing. The present study sought to clarify the nature of these associations by investigating possible longitudinal bi-directional links between self-compassion, self-criticism, and three components of positive body image (body appreciation, functionality appreciation, and body image flexibility). Data were analyzed from 2982 adult women who completed survey instruments at baseline (T0), four-month follow-up (T1), and eight-month follow-up (T2). Attrition rate ranged from 0-56% across time-points. Cross-lagged panel models were computed to test for bidirectional associations. We found evidence of reciprocal, negative associations between self-criticism and the three components of positive body image across the three time-points. We also found evidence that T0 self-compassion predicted increased body image flexibility and functionality appreciation at T1 (paths were non-significant from T1 to T2), whereas T0 body appreciation predicted increased T1 self-compassion (but was non-significant from T1 to T2). Findings suggest that compassionate and uncritical ways of responding to the self may be relevant precursors and outcomes to positive body image, depending on the timing of assessment, highlighting viable targets for intervention.

Appearance Comparisons, Affect, Body Dissatisfaction and Eating Pathology in Portuguese Female University Students

Physical appearance comparisons have been theorized to be associated with negative indicators of body image. This study aimed to study appearance comparisons and their association to affect, body dissatisfaction, and eating pathology. Three hundred and ten female university students with ages between 17 and 25 years (M = 20.2, SD = 1.9) completed sociodemographic and clinical data, self-reported questionnaires, and questions about appearance comparisons. Among the participants, 98.71% reported making appearance comparisons, and 42.15% of these reported making them frequently or always. Higher reported frequencies of appearance comparisons were related to higher levels of body dissatisfaction, negative affect, and eating pathology. Appearance comparisons to acquaintances were the most frequent. Comparisons in person and through media were reported in similar proportions. Upward comparisons were more frequent than lateral and downward comparisons and were related to higher levels of body dissatisfaction than downward comparisons and to higher levels of body dissatisfaction, negative affect, and eating pathology than lateral comparisons. Upward comparisons to close peers were associated with higher body dissatisfaction as opposed to models/celebrities. Results, limitations, and implications are discussed.

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

The current study used ecological momentary assessment (EMA) to investigate whether appearance-based comments, social and performance-based evaluations affected levels of body dissatisfaction (BD) and urges to engage in disordered eating behaviors (DE) throughout daily life. A total of 620 participants completed a baseline questionnaire assessing sociodemographic variables. Participants then downloaded a mobile app which alerted them to complete short surveys assessing their levels of BD, DE urges, and experiences of receiving comments and evaluations six times per day for 7 days. Negative appearance-based comments predicted greater levels of state BD, while positive appearance comments predicted lower levels of state BD. Negative social and performance-based evaluations predicted an increase in state BD, while positive evaluations predicted a decrease in this outcome variable. No significant predictor was found for the DE urge outcomes. The present findings suggest that receiving negative and positive feedback in various domains of one's life may predict opposite outcomes for body image. However, these effects do not necessarily associate with urges to engage in DE in a nonclinical population.

The impact of nature exposure on body image and happiness: an experience sampling study

Exposure to nature is associated with improved psychological well-being and positive body image. Here, we examined whether everyday exposure to natural environments is associated with state body image outcomes (and, for comparative reasons, state happiness) using an experience sampling method. One-hundred-and-seven participants completed a 30-day experience sampling phase in which they reported their state body image (body weight, body shape, and physical appearance satisfaction), state happiness, and features of the surrounding environment (total = 6,025 responses) at three random time-points each day. Results indicated that being outdoors was associated with significantly higher state body image on all three indicators, but effect sizes were lower compared to effects on state happiness. Specific environment type was also important, with blue-spaces and wood- and grasslands, respectively, having stronger effects than other environments. These results provide evidence that everyday exposure to natural environments is associated with more positive state body image and greater happiness.

Body image flexibility and its correlates: A meta-analysis

Body image flexibility refers to the ability to openly experience thoughts or feelings about the body without acting on them or trying to change them. Accumulating evidence has demonstrated that body image flexibility is connected to numerous adaptive processes, and that it is sensitive to change during psychological interventions. However, a quantitative synthesis of empirical research on body image flexibility is lacking. We conducted the first meta-analysis on body image flexibility and its correlates. Sixty-two studies were included. Random effects meta-analyses were conducted on 19 psychological correlates, divided into three clusters: eating and body image disturbances, positive body-related and general psychological constructs, and general psychopathology. Meta-analyses showed inverse correlations between body image flexibility and each construct within the eating and body image disturbances cluster (rs= -.45 to -.67), and the general psychopathology cluster (rs= -.37 to -.58). Body image flexibility was positively associated with each positive psychology construct (rs = .23 - .58). Men reported higher levels of body image flexibility than women (d = 0.32). Psychological interventions were more effective than control groups at enhancing body image flexibility in randomized controlled trials (d = 0.42). Findings confirm that body image flexibility is consistently connected to indices of mental health, and that it can be enhanced during psychological interventions.

The differential impact of viewing fitspiration and thinspiration images on men's body image concerns: An experimental ecological momentary assessment study

To date, little is known about the impact of fitspiration and thinspiration exposure on men, as previous studies on these social media trends were primarily conducted on women. Male participants (n = 223) completed baseline measures of trait body image, then used a smartphone application to complete up to six state-based assessments daily for seven days. In each assessment, participants were randomly assigned to one of three image conditions (fitspiration, thinspiration, or neutral). Before and after viewing each image, they reported state body fat dissatisfaction, muscularity dissatisfaction, negative mood, and urge to engage in behaviours to reduce body fat and increase muscularity. Multi-level analyses revealed that compared to viewing neutral images, viewing fitspiration images increased men's body dissatisfaction, whereas viewing thinspiration images decreased body dissatisfaction. Viewing either fit- or thinspiration images also led to lower mood and greater urges to increase muscularity, whereas only fitspiration images increased urges to reduce body fat. Men with greater baseline muscularity dissatisfaction and higher appearance comparison were most vulnerable to muscularity dissatisfaction after viewing fitspiration images. Findings suggest the importance of limiting exposure to fitspiration imagery and implementing social media literacy programmes for men and well as women.

Examining the factor structure, sex invariance, and psychometric properties of the Body Image Acceptance and Action Questionnaire and the Functionality Appreciation Scale

Body image flexibility and functionality appreciation are two facets of positive body image gaining significant research attention. The measures that assess these constructs- the Body Image Acceptance and Action Questionnaire (BI-AAQ) and Functionality Appreciation Scale (FAS), respectively-have produced a unidimensional structure with adequate psychometric properties. However, the cross-sex invariance of the BI-AAQ has yet to be established, and replicating the FAS' one-factor structure is needed. We examined the factor structure, cross-sex invariance, and psychometric properties of the BI-AAQ and FAS. Data were analyzed from 383 men and 631 women who completed questionnaires (participants were not restricted to a specific country). An unacceptable model fit for the BI-AAQ was found for men and women, indicating that the unidimensional structure was not replicated. The unidimensional structure of the FAS and an abbreviated 5-item BI-AAQ was replicated, and tests of measurement invariance between men and women were upheld. Evidence of internal consistency, convergent validity, and incremental validity for the abbreviated BI-AAQ and FAS was found. Overall, the abbreviated BI-AAQ and the FAS appear to be psychometrically sound measures of positive body image. Findings suggest that sex comparisons on the abbreviated BI-AAQ and FAS are permissible.

State-Based Markers of Disordered Eating Symptom Severity

Recent work using naturalistic, repeated, ambulatory assessment approaches have uncovered a range of within-person mood- and body image-related dynamics (such as fluctuation of mood and body dissatisfaction) that can prospectively predict eating disorder behaviors (e.g., a binge episode following an increase in negative mood). The prognostic significance of these state-based dynamics for predicting trait-level eating disorder severity, however, remains largely unexplored. The present study uses within-person relationships among state levels of negative mood, body image, and dieting as predictors of baseline, trait-level eating pathology, captured prior to a period of state-based data capture. Two-hundred and sixty women from the general population completed baseline measures of trait eating pathology and demographics, followed by a 7 to 10-day ecological momentary assessment phase comprising items measuring state body dissatisfaction, negative mood, upward appearance comparisons, and dietary restraint administered 6 times daily. Regression-based analyses showed that, in combination, state-based dynamics accounted for 34-43% variance explained in trait eating pathology, contingent on eating disorder symptom severity. Present findings highlight the viability of within-person, state-based dynamics as predictors of baseline trait-level disordered eating severity. Longitudinal testing is needed to determine whether these dynamics account for changes in disordered eating over time.

Body image in and out of the lab: Correspondence between lab-based attentional bias data and body shape dissatisfaction experiences in daily life

Accumulating lab-based studies have identified attentional biases in processing of negative appearance-related information among individuals with elevated trait body shape and weight dissatisfaction (BD). How these biases translate into experiences of BD in daily life remains unclear and, hence, was the focus of the present study. Thirty-eight women aged between 18-40 years completed a baseline survey and modified dot-probe task with both fat and thin appearance-related stimuli in a laboratory setting. Participants also downloaded a smartphone app that prompted them 10 times per day for 7 days to rate current body dissatisfaction. Results revealed that heightened BD in daily life tended to be transitory, and followed by a substantially lower rating of BD by the next survey (∼1-2 h later). For individuals with elevated trait BD and facilitated attention towards thin body images, this reduction in state BD was more gradual. Surprisingly, delayed disengagement towards thin body images was associated with greater reduction in state BD. Consistent with the hypothesis, moderating effects were not observed when initial state BD level was low. Susceptibility for immediate, short-term attentional biases towards appearance-related information may be a vulnerability factor for the prolonged persistence of negative body image experiences in daily life.
