Social appearance anxiety and dietary restraint as mediators between perfectionism and binge eating: A six month three wave longitudinal study

Anxiety and restrained eating in everyday life: An ecological momentary assessment study

BACKGROUND

Restrained eating has been related to psychological distress like anxiety and eating disorder symptomatology, but little is known about this relationship in daily life in non-clinical populations. We aimed to understand concurrent and temporal associations between momentary anxiety and restrained eating in everyday life within and across persons in a non-clinical sample, and examined whether this association remains after controlling for eating disorder symptomatology.

METHODS

We used a 10-day ecological momentary assessment (EMA) protocol. Participants (n = 123) completed a baseline survey with demographics and eating disorder symptomatology questions, and three EMA surveys per day reporting anxiety and restrained eating intentions. We applied mixed-effects and random intercept cross-lagged models to analyze the data.

RESULTS

Momentary anxiety and restrained eating were concurrently significantly positively associated within and between persons. When participants had more anxiety than was typical for them, they were more likely to intend to restrain eating, and people with overall higher anxiety symptoms tended to report greater restrained eating over the study period. These associations remained significant after adjusting for eating disorder symptomatology. There were no significant temporal cross-lagged effects. Anxiety-restrained eating association did not spill over into the next assessment window.

LIMITATIONS

The time window between prompts may have been too long to capture potential temporal effects, and we did not examine actual behavioral food restrictions.

CONCLUSION

Daily-life anxiety may be related to concurrent restrained eating intentions, above and beyond baseline eating disorder symptomatology. Research is needed exploring daily-life anxiety as a potential intervention target to address restrained eating.

Risk and resilience in eating disorders: differentiating pathways among psychosocial predictors

OBJECTIVE

Eating disorders (EDs) represent a rising global health concern. The current study takes a multivariate approach to examine psychological (i.e., perfectionism, anxiety sensitivity [AS], emotion dysregulation) and sociocultural factors (i.e., body dissatisfaction) that may relate to risk and resilience in EDs.

METHODS

Participants were 698 undergraduate students (Mage = 21, SDage = 4.02), mainly female (71%) and Hispanic (61.6%), who participated in an online survey assessing perfectionism, emotion dysregulation, AS, body dissatisfaction, and eating behaviors.

RESULTS

The results from structural equation model analyses revealed differential associations with disordered eating (DE) outcomes. Self-oriented perfectionism and dysmorphic appearance concerns were associated with increased dieting/carb restriction, desire for thinness, and binging tendencies. Specifically, emotional nonacceptance and lack of emotional awareness showed associations with elevated risk for dieting/carb restriction and purging tendencies, respectively. Conversely, lack of emotional clarity showed a protective pathway to these risk behaviors. Anxiety sensitivity cognitive concerns related to higher purging tendencies, while AS social concerns related to lower purging and binging tendencies.

DISCUSSION

Findings highlight the differential pathways of psychosocial risk and resilience for EDs. Subscales of emotional dysregulation and AS showed risk as well as resilience associations with DE outcomes. This information is key for advancing transdiagnostic prevention and intervention to reduce the rising rates of EDs.

A meta-analysis of disordered eating and its association with self-criticism and self-compassion

OBJECTIVE

Future treatments for eating disorders (ED) need to be enhanced by targeting maintaining mechanisms. Literature suggests self-criticism and self-critical perfectionism act as key mechanisms exacerbating ED, and self-compassion protects against self-criticism. This meta-analysis examines associations between self-criticism and self-critical perfectionism on disordered eating (DE), and reviews how self-compassion and self-criticism relate to each other with respect to DE.

METHOD

Searches across three databases yielded 135 studies across 42,952 participants. Heterogeneity, publication bias, and quality assessments were analyzed. Moderation analyses between self-criticism measures, self-compassion measures, between clinical and nonclinical samples, and between cross-sectional and experimental studies were also conducted.

RESULTS

Random-effects models showed a medium positive link between self-criticism and DE (r = .37), and 10 subgroups pertaining to various measures of self-criticism utilized in literature showed small to large positive links with DE (r = .20-.52). Preliminary evidence also suggests negative relationships between self-compassion and DE (r = -.40 to -.43) and negative relationships between self-compassion and self-criticism (r = -.04 to -.88).

DISCUSSION

Greater levels of self-criticism is linked with greater levels of DE and reduced levels of self-compassion, suggesting a need to tackle self-criticism and nurture self-compassion in standard treatments for ED. Understanding these interactions better in conjunction with dismantling intervention studies can help develop more effective and efficient interventions targeting self-criticism and self-compassion for people with DE.

PUBLIC SIGNIFICANCE STATEMENT

Higher levels of self-criticism are linked with higher levels of DE and lower self-compassion. Self-compassion interventions could be more effective and efficient in reducing ED symptoms if self-criticism is tackled early in such treatments.

Examination of Social Appearance Anxiety through Psychological Theories

Social appearance anxiety, which is expressed as a type of social anxiety, is defined as the state of tension and anxiety experienced by people when their physical appearance is evaluated by others. In the literature, there are studies examining the factors that increase or decrease social appearance anxiety and the negative effects of social appearance anxiety. However, it is noteworthy that psychological theories are not included in the examination of social appearance anxiety, which is a common problem experienced by almost everyone at certain periods of their lives. Addressing the concept of social appearance anxiety from a theoretical perspective will contribute to the understanding of the concept, better planning of future research, and will also fill the gap in the literature. In this context, in this review study, the concept of social appearance anxiety is explained, and then the concepts related to its analysis in terms of psychological theories are discussed.

Perfectionism and binge eating association: a systematic review and meta-analysis

BACKGROUND

Perfectionism is considered a vulnerability factor for eating disorders. However, the role of perfectionism in binge eating needs clarification due to notably inconsistencies between studies. The purpose to this study was to conduct a systematic review and meta-analysis to estimate the perfectionism-binge eating association.

METHOD

Systematic review was performed according to the PRISMA 2020 statement. Four databases (Web of Science, Scopus, PsycINFO and Psicodoc) were searched to identify studies published until September 2022. The literature search yielded 30 published articles (N = 9392) that provided 33 independent estimations of the correlation between the two variables.

RESULTS

Random-effects meta-analysis revealed a small-to-moderate positive average effect size between general perfectionism and binge eating (r₊ = .17) with a large heterogeneity. Perfectionistic Concerns showed a significant small-to-moderate relationship with binge eating (r₊ = .27), whereas Perfectionistic Strivings presented a negligible relationship with binge eating (r₊ = .07). Moderator analyses showed that the age, the type of the sample, the study design, and the tools for assessing both variables were statistically associated with the perfectionism-binge eating effect sizes.

CONCLUSIONS

Our findings suggest that Perfectionism Concerns are closely associated with binge eating symptomatology. This relationship might be moderated by certain variables, especially by the clinical or non-clinical nature of the sample and the instrument employed to assess binge eating.

Normative body image development: A longitudinal meta-analysis of mean-level change

This meta-analysis synthesized longitudinal data on mean-level change in body image, focusing on the constructs of body satisfaction and dissatisfaction, body esteem, perceived attractiveness, valuation, self-objectification, and body shame. We searched five databases and accessed unpublished data to identify studies that assessed body image at two or more time points over six months or longer. Analyses were based on data from 142 samples representing a total of 128,254 participants. The age associated with the midpoint of measurement intervals ranged from 6 to 54 years. Multilevel metaregression models examined standardized yearly mean change, and the potential moderators of body image construct, gender, birth cohort, attrition rate, age, and time lag. Boys and men showed fluctuations in overall body image with net-improvements between ages 10 and 24. Girls and women showed worsening body image between ages 10 and 16, but improvements between ages 16 and 24. Change was greatest between ages 10 and 14, and stabilized around age 24. We found no effect of construct, birth cohort, or attrition rate. Results suggest a need to revise understandings of normative body image development: sensitive periods may occur somewhat earlier than previously believed, and body image may show mean-level improvements during certain age ranges.

Prevalence and associated factors of binge eating disorder among Bahraini youth and young adults: a cross-sectional study in a self-selected convenience sample

BACKGROUND

Binge eating disorder (BED) is defined as recurrent ingestion of an unusually large amount of food in a discrete period of time. BED has the highest prevalence of all eating disorders. Studies have shown a strong relationship between BED and both physical and psychological factors such as obesity, depression and anxiety. This research aimed to report the prevalence and associated factors of BED among Bahrainis (aged 15-30 years).

METHODS

A total of 959 participants (aged 15-30 years) completed self-administered online questionnaires. BED was measured using the binge eating disorder Screener-7. The Patient Health Questionnaire-9 and General Anxiety Disorder-7 were used to measure depression and anxiety, respectively.

RESULTS

Out of all participants, 21.2% had binge eating symptoms. A higher BMI, a restricted diet, depression and anxiety were associated with more frequent binge eating symptoms. Out of all associated factors, depression had the strongest association with binge eating, (rp = 0.371, p < 0.0001). However, sociodemographic variables including age and other medical conditions were not significantly associated with BED symptoms.

CONCLUSION

In conclusion, the prevalence of BED symptoms was significantly high among the study participants. The results point out the crucial role of awareness of the interaction between obesity, depression and anxiety as potential risk factors for binge eating tendencies. Further research should examine their relationship with BED.

Appearance anxiety and social anxiety: A mediated model of self-compassion

Background

Previous studies have focused on the comorbidity of appearance anxiety and social anxiety, but few studies have focused on the protective role of self-compassion as underlying this mechanism, in young people like University students. With the increase of prevalence of appearance anxiety and social anxiety in this age group, it is necessary to explore factors that can buffer against the symptoms of these disorders. Therefore, the aims of this study were to research the effect of appearance anxiety and social anxiety, then to examine whether self-compassion has a protective effect on social anxiety.

Method

The study was cross-sectional and conducted online from October 2021 to November 2021 in Jilin Province, China. A total of 63 Universities in the province participated in this study, totaling 96,218 participants, of which 40,065 were males (41.64%) and 56,153 females (58.36%), the mean age of the sample was 19.59 (±1.74). The Appearance Anxiety Scale-Brief Version was used to measure appearance anxiety. The Social Anxiety subscale of the Self-Consciousness Scale was used to measure social anxiety. The Self-Compassion Scale-Short Form was used to measure self-compassion. A structural equation model (SEM) was run to examine the mediating effect of self-compassion on the relationship between appearance anxiety and social anxiety.

Result

Overall, appearance anxiety was positively associated with social anxiety [β = 0.334, 95% CI = (0.328, 0.341), p < 0.001], and self-compassion could mediate the effect of appearance anxiety on social anxiety [β = 0.128, 95% CI = (0.124, 0.132), p < 0.001]. Self-compassion played a partial mediating role between appearance anxiety and social anxiety.

Conclusion

Individuals with high appearance anxiety are also at higher risk of social anxiety, but self-compassion can buffer against this relationship. These findings begin to explore novel approaches to treat social anxiety and can provide valuable insights for self-compassion training.

Negative body image components as risk factors for orthorexia nervosa: Prospective findings

Emerging theoretical and empirical evidence indicates that negative body image might be implicated in the onset or maintenance of ON symptoms. However, existing research investigating associations between negative body image and ON is limited to cross-sectional designs and has failed to consider the independent role of distinct components of body image. To overcome these limitations, the present study examined the prospective associations between five components of body image (i.e., overvaluation, dissatisfaction, preoccupation, body checking, and body image avoidance) and ON symptoms in community-based adult women. Participants were assessed at baseline and at a three-month follow-up, with 558 women included in the final analyses. After adjusting for baseline ON symptoms, higher scores on each of the five body image components at baseline significantly predicted greater increases in ON symptoms in univariate analyses. However, in multivariate analyses, overvaluation with weight and shape was the only component of body image to uniquely predict ON symptoms. Findings suggest that certain components of negative body image may increase the risk for ON symptoms. Findings also lend support to recent proposals that ON may be better viewed as a variant of an existing eating disorder, given that both appear to share similar underlying risk factors.

Emotional Eating and Perfectionism as Predictors of Symptoms of Binge Eating Disorder: The Role of Perfectionism as a Mediator between Emotional Eating and Body Mass Index

(1) Background: Perfectionism has been linked to eating disorders and might be a risk factor for the appearance of eating pathologies. The aims of this study are (a) to verify the relationship between perfectionism, emotional eating (EE), binge eating (BE), and body mass index (BMI); (b) to identify the variables that predict BE symptoms and BMI; (c) to study the role of perfectionism as a mediator between EE and BMI. (2) Methods: 312 adult participants answered a cross-sectional survey that included the Multidimensional Perfectionism Scale, the Emotional Eater Questionnaire (EEQ), the Binge Eating Scale (BES), and a sociodemographic questionnaire including BMI. (3) Results: The results suggest a direct correlation between EE, BE, and BMI, showing that EE is a powerful predictor of BE symptoms and BMI. Furthermore, two dimensions of perfectionism have a mediator role between EE and BMI, specifically doubts and actions and concern over mistakes: the presence of these two components of perfectionism reverses the relationship between EE and BMI. (4) Conclusions: These results have significant implications for the understanding of the two different (pathological) eating patterns: intake restriction and overeating and should be considered in intervention programs.

Further support for the validity of the social appearance anxiety scale (SAAS) in a variety of German-speaking samples

PURPOSE

Eating disorders (ED) and social anxiety disorder are highly comorbid with potentially shared symptoms like social appearance anxiety (SAA) referring to a fear of being negatively evaluated by others' because of overall appearance. SAA constitutes a risk factor for eating psychopathology and bridges between EDs and social anxiety disorder.

METHODS

The present studies examined internal consistency, factor structure, test-retest reliability, gender and age invariance, convergent validity and differences between individuals with and without an ED of a German version of the social appearance anxiety scale (SAAS) in four independent samples (n₁ = 473; n₂ = 712; n₃ = 79; n₄ = 33) including adolescents and patients with EDs.

RESULTS

Consistently, the SAAS showed excellent internal consistency (ωs ≥ 0.947) and a one-factorial structure. Convergent validity was shown via high correlations of the SAAS with social anxiety (e.g., social interaction anxiety r = 0.642; fear of negative evaluation rs ≥ 0.694), body image disturbance measures (e.g., shape concerns rs ≥ 0.654; weight concerns rs ≥ 0.607; body avoidance rs ≥ 0.612; body checking rs ≥ 0.651) and self-esteem (r = -0.557) as well as moderate correlations with general eating psychopathology (e.g., restrained rs ≥ 0.372; emotional r = 0.439; external eating r = 0.149). Additionally, the SAAS showed gender and age invariance and test-retest reliability after 4 weeks with r = 0.905 in Study 2 and was able to discriminate between individuals with and without an ED in Study 4.

CONCLUSION

Hence, the German version of the SAAS can reliably and validly assess SAA in female and male adolescents or adults with or without an ED. Additionally, the SAAS might be used in a therapeutic context to especially target patient groups suffering from EDs with comorbid social anxiety.

Nutrition knowledge moderates the association between perfectionism and shape/weight concerns

Perfectionistic traits have been associated with stronger weight and diet concerns. Maladaptive perfectionism is tied to critical evaluation tendencies such as excessive concern about making mistakes, increasing one's risk for eating disorder pathology. Knowledge about healthy diet and nutrition may be one factor influencing associations between perfectionistic tendencies, as individuals with eating disorders may be more attuned to sources of nutrients. The current study examined whether nutrition knowledge moderates the association between one facet of perfectionism, concern over mistakes, and shape/weight concerns and the association between concern over mistakes and global eating pathology. College women (N = 122) completed questionnaires on disordered eating attitudes, nutrition knowledge, and perfectionism. Concern over mistakes was positively related to shape/weight concerns and global eating pathology. Nutrition knowledge significantly moderated the association between concerns over mistakes and shape/weight concerns, such that the association was stronger among those with higher levels of nutrition knowledge. Furthermore, nutrition knowledge displayed trend-level significance for the moderation of the association between concern over mistakes and global eating pathology. College women displaying high levels of concern over mistakes who are more informed about nutrition knowledge may be more vulnerable to developing concerns about body shape/weight and eating disorder pathology.

Measuring perfectionism, impulsivity, self-esteem and social anxiety: Cross-national study in emerging adults from eight countries

This study assessed the measurement invariance of selected self-report measures of perfectionism, impulsivity, self-esteem and social anxiety in samples of emerging adults from eight different countries. Participants (N = 6272) completed the Multidimensional Perfectionism Scale (MPS), the UPPS-P Impulsive Behavior Scale, the 5-item Rosenberg Self-Esteem Scale (5-item RSES) and the Social Interaction Anxiety Scale (SIAS-6). Multigroup confirmatory factor analysis was run to examine cross-measure equivalence. Evidence for structural invariance was found for all questionnaires, while weak invariance was supported only for the 5-item RSES and the SIAS-6, and a partial weak invariance was found for the MPS and the UPPS-P. No measure achieved strong invariance. Strict invariance was achieved for the 5-item RSES, whereas only a partial strict invariance was supported for the MPS, UPPS-P and SIAS-6. These results suggest that perfectionism, impulsivity, self-esteem, and social anxiety are subjected to linguistic/cultural influence as well as to the effects of socio-demographic variables and can be evaluated by using the selected measures in eight different countries worldwide - but results should be interpreted with caution.

Risk factors and temporal patterns of disordered eating differ in adolescent boys and girls: Testing gender-specific appearance anxiety models

Adolescent dieting and disordered eating (DE) are risks for clinical eating disorders. In this five-wave longitudinal study, we tested gender-specific models linking early risk factors to temporal patterns of DE, considering appearance anxiety as a mediator. Participants were 384 Australian students (age 10 to 13; 45% boys) who reported their purging and skipping meals, experience with appearance-related teasing, media pressure, and appearance anxiety. Parents reported pubertal maturation and height/weight was measured. Gender differences in temporal patterns of DE were found and predictive models were tested using latent-variable growth curve and path models. Boys’ DE was generally stable over time; girls showed stability in purging but an average increase in skipping meals. Peer teasing, media pressure, and pubertal maturation were associated with more elevated initial DE in girls, and pubertal maturation was associated with a steeper increase in DE. For boys, body mass index had a direct positive association with DE. Appearance anxiety was associated with more DE, but there was only one significant indirect effect via anxiety, which was for boys’ pubertal maturation. Findings support the dominant role of social interactions and messages, as well as pubertal maturation, for girls’ DE and the prominence of physical risk factors for explaining boys’ DE.

Linking body esteem to eating disorders among adolescents: A moderated mediation model

This study explored the roles of social appearance anxiety and emotional intelligence in the relationship between body esteem and eating-disorder risk among adolescents. A total of 2509 high-school students were sampled to participate in the study. Statistical methods mainly involved descriptive statistics, Bootstrapping, and structural equation modeling analyses. The results showed that social appearance anxiety partially mediated the relationship between body esteem and eating-disorder risk among adolescents; meanwhile, emotional intelligence moderated the effects of body esteem on social appearance anxiety and eating-disorder risk among adolescents.

Psychological Predictors of Unhealthy Eating Attitudes in Young Adults

The objective of this study was to determine the predictive role of psychological risk factors for restrained and compulsive eating in young women and men. We examined the relationship between resilience, impulsivity, emotional intelligence and self-esteem, and restrained and compulsive eating. It was assumed that resilience and impulsivity can directly explain unhealthy eating attitudes (restrained and compulsive: both emotional eating and external eating). The study group comprised 211 individuals (105 men and 106 women) aged 20-29, all of whom were living in southern Poland. Measures included the Resilience Measurement Scale (SPP-25), the Eysenck's Impulsivity Inventory (IVE), the Multidimensional Self-Esteem Inventory (MSEI), the Emotional Intelligence Questionnaire (INTE), and the Polish adaptation of the Dutch Eating Behavior Questionnaire (DEBQ). The statistical analysis showed significant and positive correlations between emotional eating and general self-esteem, impulsivity, and weaker (but still significant) correlations with physical attractiveness. External eating was positively and significantly correlated with impulsivity and self-esteem (including physical attractiveness). Restrained eating was also positively and significantly correlated with general self-esteem. Both types of compulsive eating attitudes (emotional and external eating) were significantly and negatively correlated with resilience. Women showed a significantly higher positive correlation between impulsivity and external eating compared to men. The level of intensity of other measures proved similar across the entire study group regardless of sex. Impulsivity had the strongest and most direct significant influence on both emotional eating and external eating, and a negative effect on emotional intelligence. Resilience proved to have a significant impact on all three examined types of eating attitude (a direct negative effect on emotional eating and external eating, and positive direct effect on restrained eating), self-esteem, and emotional intelligence. An important psychological intervening variable in generating unhealthy eating attitudes proved to be self-esteem among both men and women. Emotional intelligence, which remains correlated with resilience, proved independent, with no effect on unhealthy eating attitudes. These results suggest that preventive treatment and educational programs implemented particularly among adolescents and young adults may support development of their psychological resources.

Male Nursing Students' Social Appearance Anxiety and Their Coping Attitudes

This study aimed at examining social appearance anxiety levels of male nursing students and their coping attitudes and identifying the relationship between them. A cross-sectional research approach was adopted in a study population of 180; the sample comprised 129 students. Data were collected using a socio-demographic information form, the Social Appearance Anxiety Scale (SAAS), and the Assessment of Coping Attitudes Inventory (COPE). The average age of students was 20.54 ± 1.49 years. The male students' average score obtained from the SAAS measure was 32.64 ± 13.07, while that of the COPE Inventory was 138.11 ± 14.47. Significant correlations were detected between students' SAAS scores and COPE scale scores. There were negative relationships between social anxiety scores and COPE subscales of positive reinterpretation and growth ( p < .05), use of instrumental social support ( p < .05), active coping ( p ≤ .01), and planning ( p ≤ .01). In contrast, there were positive relationships between social anxiety scores and COPE subscales of mental disengagement ( p ≤ .01), denial ( p ≤ .01), behavioral disengagement ( p ≤ .01), restraint ( p ≤ .01), use of emotional social support ( p < .05), substance use ( p ≤ .01), and acceptance ( p < .05). The conclusion was that male students who do not perceive themselves as having an ideal body image face high social appearance anxiety. There is a prejudice that social appearance anxiety has negative effects on these students' self-confidence. In this context, this research revealed concrete results about how male nursing students have battled the prejudices that they have faced throughout their student life.

Determining the relationship between body mass index, healthy lifestyle behaviors and social appearance anxiety

The aim of this study was to describe the relationship between nutritional status, healthy lifestyle behaviors and social appearance anxiety of individuals aged 20-65 (n = 500). A significant, positive relationship was seen between body mass index and nutrition, and negative relationship between body mass index and spiritual development, interpersonal relations, stress management. There was a negative relationship between the ORTO-15 score and health responsibility, physical activity, nutrition, spiritual development, interpersonal relationships, stress management. There was also a negative relationship between the Social Appearance Anxiety Scale and spiritual development, interpersonal relationships.
