Body talk and body dissatisfaction in Japanese university students: Longitudinal study using the Japanese Body Talk Scale

This study evaluated the reliability and validity of the Japanese version of the Body Talk Scale (BTS), designed to measure negative fat talk, negative muscle talk, and positive body talk. The study also explored the longitudinal associations between each body talk category and body dissatisfaction. We conducted two separate studies among university students in Japan. Separate confirmatory factor analyses for female and male data indicated that the initially proposed three-factor model demonstrated an acceptable fit, whereas the bi-factor model provided a better fit. The Japanese BTS showed good construct validity, acceptable to adequate internal consistency, and test-retest reliability within 2 weeks. A four-week longitudinal study involving 386 women and 216 men (mean age = 19.22 and 19.62, respectively) revealed that negative fat talk predicted an increase in the discrepancy between the thin ideal body image and the actual body image among women. In contrast, positive body talk was linked to reduced body dissatisfaction and body image discrepancy in women. There were no such significant associations in men. These findings support the use of the Japanese BTS as a valuable instrument for future research on the intrapersonal and interpersonal effects of various types of body talk.

Links of weight and muscularity teasing with eating disorder symptomatology, eating-related psychosocial impairment, and intuitive eating in Chinese men: Teasing directions and combinations matter

Empirical evidence, based on variable-centered approaches (e.g., correlation and regression analyses), supports robust links between weight and muscularity teasing and eating variables in men. However, limited research has considered the directions (i.e., high and low) of teasing or their combinations via person-centered approaches (e.g., latent class analysis). Thus, this study explored the relationships between four types of teasing (i.e., teasing for high weight, low weight, high muscularity, and low muscularity) and eating variables in 596 Chinese adult men using variable and person-centered approaches. Independent t-tests and regression analyses revealed that four types of teasing had unique associations with eating disorder (ED) symptomatology, eating-related psychosocial impairment, and intuitive eating. Latent class analysis identified four distinct teasing classes, including High Weight-Low Muscularity, Low Weight-Low Muscularity, Low Teasing, and High Weight-High Muscularity. Notably, individuals in the Low Teasing group consistently showed the lowest ED symptomatology and psychosocial impairment and the highest intuitive eating. Individuals in the High Weight-High Muscularity group exhibited the highest traditional ED symptomatology and the most severe psychosocial impairment. The findings highlight the importance of future research considering teasing directions and tailored interventions for adult men in certain subgroups at risk of eating disorder psychopathology (e.g., the High Weight-High Muscularity teasing group).

Adaptation and validation of the muscle dysmorphic disorder inventory in a population of French athletes (MDDI-Fr)

INTRODUCTION

Muscle dysmorphia, a theme mainly investigated by Anglo-Saxon research, is a specific body dysmorphic disorder that characterizes individuals who think they are insufficiently muscular and lean. Understudied in francophone countries, tools translated and validated in French to measure the symptomatology of muscle dysmorphia remain rare.

OBJECTIVES

The aim of this study was the translation into French and the psychometric validation of a tool evaluating muscle dysmorphia, the Muscle Dysmorphic Disorder Inventory (MDDI-Fr), through 13 items divided into three dimensions: the "Drive For Size" (DFS), the "Appearance Intolerance" (AI) and the "Functional Impairment" (FI).

METHODOLOGY

A first translation step was conducted, followed by two cross-sectional studies conducted in France. In both of the latter studies, a sociodemographic questionnaire and the Muscle Dysmorphic Disorder Inventory - French version (MDDI-Fr) were administered. The first study included 342 university students (Mage=20.9; SDage=2.9), and 1822 athletes for the second study (Mage=23.9; SDage=5.9). Validation was performed using internal consistency measures and confirmatory factor analysis.

RESULTS

The correlation matrices showed good significant results between items and dimensions. The three dimensions appeared distinct from each other with significant intra-dimension correlations. The internal consistency of the tool and its three dimensions show valid Cronbach's alphas (study 1: DFS=0.79, AI=0.74, FI=0.75, MDDI=0.74; study 2: DFS=0.72, AI=0.75, FI=0.83, MDDI=0.75). In addition, the tri-factor analysis shows significant and promising scores for the tool in three dimensions and 13 items for study 1 (χ2/df=4.67, CFI=0.85, TLI=0.83, RMSEA=0.10, SRMR=0.00), as for study 2 (χ2/df=16.08, CFI=0.87, TLI=0.84, RMSEA=0.09, SRMR=.06). Gender analyses were conducted on study 2, which showed that the DFS subscale (items 1, 4, 5) and the AI subscale (items 6 and 9) presented the greatest differences in factor loadings between genders.

CONCLUSION

The translation, as well as the validation of the MDDI-Fr structured with 13 items and three dimensions, showed significantly satisfying results for its adaptation in French in a population of French men and women practicing weight training. However, the "Appearance Intolerance" dimension shows moderate links with the global tool, which should be investigated in future studies. Although the psychometric properties of the MDDI-Fr are promising, additional research is needed to gain a better understanding of gender differences in the results, especially for the DFS dimension.

A Pilot Study Testing A New Visual Stimuli Database for Probing Men's Gender Role Conflict: GRASP (Gender Role Affective Stimuli Pool)

Gender Role Conflict (GRC) yields intensive psychological discomfort due to restrictive gender roles. However, there is no visual stimuli database portraying GRC contexts/domains. The goal of this pilot study is to assemble stimuli (a) reflecting GRC contexts and (b) rate them on emotional dimensions (valence, arousal, uneasiness), for norming purposes. Initially, 53 photos were included from the Nencki Affective Picture System and the internet. Based on the four GRC domain definitions, we divided the photos into four categories. Straight and gay men (n = 22) rated each photo on (i) the extent to which it depicted a GRC domain, (ii) the three emotional dimensions. Photos rated above scale midpoint as depicting a GRC domain were classified accordingly and comprised the "Gender Role Affective Stimuli Pool" (GRASP) with 31 photos. Straight participants rated Restricted Emotionality (RE) and Restrictive Affectionate Behavior Between Men (RABBM) photos as less pleasant (low valence) than gay men. High GRC participants rated RE photos as more pleasant and arousing and RABBM ones as more uneasiness-inducing than low GRC participants. Men seem to differentiate their affective reaction to photos illustrating GRC domains; hence, GRASP may be useful to future experimental research examining cognitive and affective consequences of men's adherence to gender roles.

Gender similarities and differences in associations between weight discrimination, shape/weight concerns, and eating disorder symptoms among post-9/11 veterans

OBJECTIVE

Weight discrimination, defined as mistreatment of people based on body weight, is associated with body image concerns and eating disorder (ED) symptoms. Military veterans are particularly vulnerable to developing ED symptoms, which may be due to experiences of weight discrimination resulting from the military's strict weight and fitness requirements. However, no previous study has examined these associations among veterans. We investigated relationships between weight discrimination during and after military service and shape/weight concerns and ED symptoms in post-9/11 veterans. Based on evidence for gender differences in weight discrimination, body image, and ED symptoms, we also examined whether gender moderated these associations.

METHOD

Participants were randomly selected from the population of post-9/11 U.S. veterans who had been discharged from the military within the previous 18 months. A total of 1494 veterans completed the Everyday Discrimination Scale, Eating Disorders Examination-Questionnaire, and the Eating Disorder Diagnostic Scale-5.

RESULT

Women were more likely to report weight discrimination and had higher levels of ED symptoms and shape/weight concerns than men. Weight discrimination in and after leaving the military were positively associated with shape/weight concerns and ED symptoms in the full sample and among men and women. Gender moderated the association between weight discrimination after leaving the military and shape/weight concerns such that the association was stronger among men.

DISCUSSION

Both male and female veterans may be vulnerable to developing ED symptoms, in part due to weight discrimination experienced during and after military service. Our findings emphasize the need to address weight discrimination and its consequences in veterans.

Men's perception of current and ideal body composition and the influence of media internalization on body judgements

Introduction

To determine men's body ideals and the factors that influence these choices, this study used a matrix of computer generated (CG) male bodies (based on an analysis of 3D scanned real bodies) which independently varied in fat and muscle content.

Methods

Two hundred and fifty-eight male participants completed a range of psychometric measures to index body concerns and body ideal internalization and then chose the CG body that best reflected their own current body, as well as the body that reflected their personal ideal. A subset of participants was then retested to check that these judgements were stable over time.

Results

While judgements of the ideal body seem to be influenced by a shared appearance ideal, the degree to which this ideal was internalized showed significant variability between participants. The effect of this internalization was reflected in the difference between the estimated current body and the ideal.

Discussion

Higher internalization led to a preference for higher muscle and lower fat content. This preference was most marked for fat content, although reducing adiposity also made the underlying musculature more salient. Additionally, the ideal body composition was modulated by the composition the participant believed his current body had (i.e., it seemed that a participant's ideal body was anchored by what they believed to be their current body and what change was possible from this starting point).

Self-Compassion May Have Benefits for Body Image among Women with a Higher Body Mass Index and Internalized Weight Bias

Negative attitudes towards one’s own body are common among women and are linked to adverse consequences including negative affect, low self-esteem, and eating pathology. Self-compassion has been found effective in improving body image; however, few published studies have examined self-compassion in populations with higher BMIs despite the positive correlation between weight and body dissatisfaction. The current study examined the efficacy of a self-compassion letter-writing exercise versus two active control groups in response to a negative body image induction. The sample of college-aged females (M age = 20.91 years; SD = 5.47) was split between higher and lower BMI to determine whether self-compassion affects body image, affect, and self-esteem differently across weight groups. Weight bias internalization (WBI: i.e., internalization of society’s negative stigma against those with higher BMIs) was examined as a moderator of this relationship in the higher BMI group. Results suggest that letter writing improved body image regardless of condition (p < 0.001). The self-compassion exercise promoted more adaptive body image (p = 0.007) and self-compassion (p = 0.013) than one control condition for those with high WBI. Results suggest that self-compassion can be helpful in ameliorating negative body image for females of all sizes, and that levels of WBI may alter the effect of body image interventions.

Acute Psychological Effects of Resistance Exercise in Men With Symptoms of Muscle Dysmorphia: A Pilot Study

ABSTRACT

SantaBarbara, NJ, Nosrat, S, Whitworth, JW, Ciccolo, JT. acute psychological effects of resistance exercise in men with symptoms of muscle dysmorphia: A pilot study. J Strength Cond Res 37(2): 277-283, 2023-This study tested the acute psychological effects of resistance exercise in men with symptoms of muscle dysmorphia. Twenty-one men completed 4 on-site sessions including a single session of moderate- (70% of 10 repetition maximum [RM]) and high- (100% of 10RM) intensity resistance exercise in a counter balanced order separated by at least 48 hours. State body image, perceived muscle size, exercise enjoyment, and ratings of perceived exertion (RPE) were assessed before, during, and after each session, and statistical significance was set a priori at p < 0.05. State body image significantly improve from pre to post during both sessions ( p < 0.01), with greater effect sizes seen for the high- ( d = 0.57) compared with the moderate- ( d = 0.39) intensity session. Perceived muscle size improved from pre to post during the high-intensity only ( p < 0.01, d = 0.66), and subjects enjoyed the high-intensity session significantly more than the moderate-intensity session ( p = 0.01), despite significantly higher RPE at each timepoint ( p < 0.01). Results contend with previous findings that show more positive psychological effects of moderate- compared with high-intensity resistance exercise. Education and client observation are essential to be aware of the potential for muscle dysmorphia. In instances where muscle dysmorphia is suspected, referral to qualified mental health professionals is recommended.

The degree to which the cultural ideal is internalized predicts judgments of male and female physical attractiveness

We used attractiveness judgements as a proxy to visualize the ideal female and male body for male and female participants and investigated how individual differences in the internalization of cultural ideals influence these representations. In the first of two studies, male and female participants judged the attractiveness of 242 male and female computer-generated bodies which varied independently in muscle and adipose. This allowed us to map changes in attractiveness across the complete body composition space, revealing single peaks for the attractiveness of both men and women. In the second study, we asked our participants to choose the most attractive male and female bodies in a method of adjustment task in which they could independently vary muscle and adipose to create the most attractive body. We asked whether individual differences in internalization of cultural ideals, drive for muscularity, eating disorder symptomatology and depressive symptoms could systematically shift the location of peak attractiveness in body composition space. We found a clear preference by both genders for a male body with high muscle and low adipose, and a toned, low adipose female body. The degree of internalization of cultural ideals predicted large individual differences in the composition of the most attractive bodies.

Body image shame in men: confirmatory factor analysis and psychometric properties of the Body Image Shame Scale

PURPOSE

Body image shame plays a key role in disordered eating symptoms and psychological adjustment. Nonetheless, research has been mainly focussed on women. The Body Image Shame Scale (BISS) was previously developed and tested in a nonclinical sample of women. This study examines the BISS in a sample of men comprising students and community participants.

METHODS

Participants were 420 men, who completed the BISS and self-report measures of shame, self-criticism, body weight and shape concerns, and psychopathological symptoms.

RESULTS

The previously identified structure of the BISS, with an external and internal dimension, fitted the data well. All items presented high reliability. The BISS total score and its subscales in men present high construct reliability, and convergent and discriminant validity. Correlation analyses indicated that BISS and its subscales in men present positive associations with general shame and self-criticism, body weight and shape concerns, and with indices of poorer psychological adjustment.

CONCLUSION

Findings supported that the BISS is a reliable measure to assess body shame in men.

Analysis of Adolescent Physical Activity Levels and Their Relationship with Body Image and Nutritional Habits

The main objective of this research article was to make a cluster analysis in Compulsory Secondary Education students with regard to their physical activity levels, their relationship with nutritional habits and body perception. In this study, a total of 1089 students participated, to whom a battery of tests was given in order to assess three aspects: levels of physical activity, food consumption habits and perception of body image. The main results indicated that the adolescent sample presented high levels of physical activity in comparison with other studies. In addition, a profile analysis was carried out, showing that there were no differences in physical activity, in nutritional habits or in body-image index. Taking into account gender, women who practice light physical activity had better nutritional habits. On the other hand, boys dominated in the group of moderate-to-high physical activity, while the girls were mainly included in the profile of low physical activity. Finally, body-image index was greater in men than women. It was concluded that is necessary to promote the importance of adequate nutritional habits in addition to physical activity, and it is necessary to promote body image, particularly among adolescent girls, given their low values of physical activity and worse body-image perception in relation to boys.

Which are the Effects of Body-Objectification and Instagram-Related Practices on Male Body Esteem? A Cross-Sectional Study

OBJECTIVE

According to the objectification framework, media pressure toward body models promotes the internalization of beauty ideals that negatively influence individuals' body image and self-esteem. Historically, women have been the main target of sociocultural pressures. However, research has recently suggested that self-objectification is a male phenomenon as well, which can be inscribed in men's body experiences. Nevertheless, fewer studies have specifically focused on the male experience and general consequences of body-objectification are yet to be extensively analyzed regarding males' body image features. The current cross-sectional study explores the consequences of body-objectification on male body esteem, specifically testing the predictive role of exercising/dietary habits, body-objectification features, and SNS-related practices on male body esteem.

METHOD

A total of 238 male participants (mean age = 24.28 years, SD = 4.32) have been involved in an online survey. Three hierarchical analyses were performed to test the influence of objectified body consciousness and social networking-related experiences (i.e. Instagram intensity use, photo manipulation, selfie feedback investment) on young men's body esteem with specific reference to the weight, appearance, and attribution features of the Body Esteem Scale.

RESULTS

Findings highlighted that body shame played an interesting key role, influencing negatively all the body esteem dimensions, thus highlighting that attention needs to be deserved on this feature of OBC regarding males' experience. On the contrary, appearance control-related dimensions positively influenced body esteem. Overall, findings confirmed that objectification theory can adequately mark a pathway by which media imagery is internalized also by men and may negatively affect their body esteem.

CONCLUSIONS

Despite some limitations, this study may contribute to enlarging our knowledge on male body image and self-objectification experience and support literature shattering the stereotype that body dissatisfaction is a "female-exclusive" issue. Likewise, beyond some questioning positions, these findings also encourage further exploration of a healthier "control dimension", including body appearance-related activities and beliefs.

"Having a non-normative body for me is about survival": Androgynous body ideal among trans and nonbinary individuals

The present study focused on trans and nonbinary (TNB) individuals who have an androgynous or non-stereotypical body ideal, with attention to how their body ideal is conceptualized and maintained. Data were collected online from 76 TNB individuals. Based on responses to two open-ended prompts, a two-tiered analysis was conducted. First, thematic analysis was used to develop four central themes describing the way TNB individuals conceptualized their androgynous body ideal: 1) Attaining Neutrality and De-Categorizing Gender; 2) Disaggregating Gender Expression; 3) Managing Gender Dysphoria; and 4) Achieving Authenticity. Second, content analysis was used to document 12 behaviors engaged in or actions taken for the purpose of approaching or maintaining an androgynous or non-stereotypical body ideal. These were grouped into 3 main categories: gender expression (clothes, hair, make-up, body modifications), body shape (weight, muscularity, eating/diet), and sex characteristics (hormone therapy, body hair, vocal, chest, genitals). Results of the present study expand the current body ideal literature by including TNB narratives and by focusing specifically on the ways an androgynous body ideal is conceptualized and maintained. Research and clinical implications are discussed.

Body Dissatisfaction and Its Association with Health-Related Factors in Rural and Urban Mexican Adolescents from the State of Jalisco

Background: To better understand Mexican adolescent’s body self-perception, this study aimed to analyze their body dissatisfaction (BD) levels according to sex and place of residence. We also aimed to explore differences in body composition (BC), physical fitness (PF), and physical activity (PA) between satisfied and dissatisfied adolescents and to find the associations between BD and these parameters. Methods: Cross-sectional, observational study carried out in Jalisco (Mexico) in which 451 adolescents (43.68% males, 43.90% rural) aged 13–17 years were evaluated. BD and self-perceived PF and PA were assessed with validated questionnaires, while objectively measured PF (strength, explosive strength, speed-agility, and cardiovascular fitness) was assessed using field tests. To evaluate BC, anthropometric measures and bioelectric impedance analysis were carried out. Regression analysis was used to ascertain the associations between health-related factors and body dissatisfaction. Results: Girls obtained higher scores on the BD questionnaire than boys (11.12 ± 3.13 vs. 10.33 ± 2.73; p < 0.05), whereas no geographical differences between rural and urban adolescents were found. BD was positively associated with higher fat mass (β = 0.15; p < 0.001), and negatively associated with muscle mass and PF (β = −0.24 and β = −0.23; p < 0.001). However, PA was not associated with any of the measured parameters. Conclusions: selected parameters of BC, PF, and sex have an impact on the Mexican adolescent’s body satisfaction levels and should be considered when designing future health policies.

Appearance-Related Partner Preferences and Body Image in a German Sample of Homosexual and Heterosexual Women and Men

There is evidence that gender as well as sexual orientation can affect body image. In particular, heterosexual women and homosexual men seem to be more vulnerable to a negative body image compared to homosexual women and heterosexual men. One reason for this may be derived from the fact that heterosexual women and homosexual men try to attract male romantic partners: As men place more importance on physical attractiveness than do women, the pressure to fulfill the sociocultural beauty ideal is thus increased. The present online study investigated differences in appearance-related partner preferences and their associations with measures of body image and eating pathology in homosexual and heterosexual women and men. The non-representative sample consisted of 893 participants (n = 201 lesbian women, n = 192 gay men, n = 349 heterosexual women, and n = 151 heterosexual men), who completed silhouette measures assessing their perception and expectations regarding body fat and muscularity of their own body and the body of a potential romantic partner, as well as questionnaires on drive for thinness, drive for muscularity, and eating pathology. Overall, few differences in appearance-related partner preferences emerged between the four groups. However, compared to heterosexual women, homosexual men appeared to prefer higher muscularity in potential romantic partners, which was also associated with increased drive for thinness and muscularity and increased eating pathology. The present findings indicate that, irrespective of sexual orientation, women and men tend to share similar standards regarding their own and a potential partner's physical appearance, potentially suggesting an increased hegemony of heteronormative beauty ideals in women and men in general.

3D visualisation of psychometric estimates for the ideal male body

Psychological concerns are frequently indexed by psychometric questionnaires but the mental representations that they seek to quantify are difficult to visualise. We used a set of questionnaires designed to measure men's concept of their bodies including: the Drive for Muscularity Scale (DMS; McCreary & Sasse, 2000), the Perceived Sociocultural Pressures Scale (PSPS; Stice, Nemeroff, & Shaw, 1996a), the Body Appreciation Scale (BAS-2; Tylka & Wood-Barcalow, 2015), and the Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3; Thompson, van den Berg, Roehrig, Guarda, & Heinberg, 2004). We combined their use with an interactive 3D modelling programme to allow men to create computer-generated representations of their ideal bodies. We used a principal component analysis to extract those shape components of our participants' CGI ideal bodies that were predicted by the questionnaires and reconstructed the body shapes that these questionnaires were capturing. Moving from the lowest to the highest score on both the DMS and SATAQ corresponded with changes in muscularity, particularly muscle mass and definition. This approach allows us to demonstrate the actual body features that are being captured by a particular questionnaire.

Disordered eating and body change behaviours: support for the Tripartite Influence Model among Brazilian male university students

The Tripartite Influence Model posits that sociocultural influences mediated by internalization and social comparison are predictors of disordered eating and body change behaviours. This study aimed to test the Tripartite Influence Model among Brazilian male university students, which has not been tested yet. 707 undergraduate students of the five Brazilian regions, completed measures of sociocultural influences, internalization, social comparison, body and muscularity dissatisfaction, disordered eating and body change behaviours. Structural equation modelling analyses showed good model-fitting. Parental influence was related to internalization, while peer influence with social comparison. Media influences were related to both internalization and social comparison. Internalization and social comparison are mediating variables that are related to body dissatisfaction and muscularity dissatisfaction. Finally, muscularity dissatisfaction was associated with body change behaviours.

Development and validation of the body shape scale (BOSHAS) for assessing body shape perception in African populations

Background

As a consequence of ‘Western’ acculturation, eating disorders and body image disturbances, such as fatness phobia and body dysmorphic disorders towards musculature and body shape, are emerging in Africa, with young people the most affected. It is therefore important to accurately assess perceptions of body shape. However, the existing body image assessment scales lack sufficient accuracy and validity testing to compare body shape perception across different African populations. The purpose of this study was to develop and validate the Body Shape Scale (BOSHAS) to evaluate body shape perceptions related body image disorders in African populations.

Methods

To develop the BOSHAS, anthropometric measures of 80 Cameroonians and 81 Senegalese (both sexes included; 40.1% females overall) were taken for three body shape criteria: somatotype components, body mass index (BMI) and waist-to-hip ratio. Subjects were selected to cover a wide variability in body shape and were photographed in full face and profile positions. To validate the BOSHAS, the scale was administered twice (2 weeks apart) to 106 participants (aged 31.2 ± 12.6 years) to assess its reliability. In addition, a questionnaire measuring different aspects of body shape (e.g. musculature) was also administered (n = 597; aged 36.7 ± 15.6 years) to assess its convergent validity.

Results

The BOSHAS includes two sex-specific subscales of 10 photographs each. Most participants were able to repeat their BOSHAS preference order. Test-retest reliability was also consistent in estimating Current Body Shape (CBS), Desired Body Shape and Ideal Body Shape for participants and their partners. CBS was correlated with BMI, and different BOSHAS indices were consistent with declarations obtained by questionnaire.

Conclusions

The BOSHAS is the first sex-specific scale of real African models photographed in face and profile, including large body shape variability. The validation protocol showed good validity and reliability for evaluating body shape perceptions and dissatisfaction of Africans.

Beyond BMI for self-estimates of body size and shape: A new method for developing stimuli correctly calibrated for body composition

Accurate self-assessment of body shape and size plays a key role in the prevention, diagnosis, and treatment of both obesity and eating disorders. These chronic conditions cause significant health problems, reduced quality of life, and represent a major problem for health services. Variation in body shape depends on two aspects of composition: adiposity and muscularity. However, most self-assessment tools are unidimensional. They depict variation in adiposity only, typically quantified by the body mass index. This can lead to substantial, and clinically meaningful, errors in estimates of body shape and size. To solve this problem, we detail a method of creating biometrically valid body stimuli. We obtained high-resolution 3D body shape scans and composition measures from 397 volunteers (aged 18-45 years) and produced a statistical mapping between the two. This allowed us to create 3D computer-generated models of bodies, correctly calibrated for body composition (i.e., muscularity and adiposity). We show how these stimuli, whose shape changes are based on change in composition in two dimensions, can be used to match the body size and shape participants believe themselves to have, to the stimulus they see. We also show how multivariate multiple regression can be used to model shape change predicted by these 2D outcomes, so that participants' choices can be explained by their measured body composition together with other psychometric variables. Together, this approach should substantially improve the accuracy and precision with which self-assessments of body size and shape can be made in obese individuals and those suffering from eating disorders.

Body Image Problems and Disordered Eating Behaviors in Italian Adolescents With and Without Type 1 Diabetes: An Examination With a Gender-Specific Body Image Measure

Objective

To examine body image problems and their associations with disordered eating behavior in adolescents with type 1 diabetes and well-matched healthy peers.

Methods

Using a cross-sectional design, 183 adolescents with type 1 diabetes (13.02–18.05 years) were recruited from diabetes centers in southern Italy and compared to healthy peers matched for age and gender. Participants completed self-report measures of disordered eating behaviors (DEPS-r and EDI-3RF) and a gender-specific body image problem questionnaire (SATAQ-4R). Socio-demographic and clinical data (zBMI, HbA1c, and disease duration) were also collected. Hierarchical multiple linear regression analyses were computed to determine the relative importance of diabetes variables and body image problems on participants’ disordered eating behaviors after controlling for demographic variables.

Results

Adolescents with type 1 diabetes showed diabetes-specific eating problems in 37.7% of cases and had more eating problem symptoms (assessed as drive for thinness and bulimia) than healthy peers. Male adolescents with type 1 diabetes did not display more body image problems (p > 0.05); females with type 1 diabetes compared to females in the control group were found to be more pressured by family (p = 0.025) but less by media (p = 0.022) to improve their appearance and attain a thin body. zBMI and body image problems contributed to a significant increase in disordered eating behavior risk both in male and female adolescents with diabetes and in healthy peers (zBMI 0.213 < β < 0.426, p < 0.05; body image 0.243 < β < 0.572, p < 0.05). None of the variables analyzed were found to significantly predict male bulimic symptoms (all β < 0.296, p > 0.05).

Conclusion

Since in adolescence type 1 diabetes and insulin therapy may increase the risk of weight gain and promote focus and attention on the body and thus contribute to the development of body image problems and disordered eating behaviors, continuity of medical, nutritional, and psychological care is needed.

The Thin Man is His Clothing: Dressing Masculine to be Masculine

Body image research focuses almost exclusively on women or overweight and obesity or both. Yet, body image concerns among thin men are common and can result, at least in part, from mixed messages in society around how men qua men should dress and behave in order to look good and feel good. Stand-alone interventions to meet these different messages tend to provide men with little therapeutic relief. This conceptual paper draws on literature from the medical humanities; gender and body image studies; the social psychology of clothing; and the author's own lived experience to address this contemporary problem. The paper embraces visual culture as a resource that can frame discussion of how two sets of 'performativity' might reduce male anxiety about thinness. First, thin men could choose repeatedly to wear masculine-looking clothing, which could create their masculinity as a personal aesthetic that strengthens the confidence to harness masculine traits in healthy ways. Secondly, health and allied health service providers could promote and reinforce such dress behavior by offering advice that integrates aesthetic and functional aspects of clothing. Empirical studies are needed to test this dual model of performativity.

Development and validation of new figural scales for female body dissatisfaction assessment on two dimensions: thin-ideal and muscularity-ideal

Background

Body dissatisfaction influences women’s mental and physical health. To date, most research has focused on body dissatisfaction in relation to the ‘thin-ideal’. Thus, the association between body dissatisfaction, eating disorder symptomatology and muscularity-ideal in women is less clear. Lack of understanding is underpinned by the lack of reliable and valid muscularity-related assessments for women. To address this need, we developed, tested and re-tested two new body dissatisfaction scales: The Female Body Scale (FBS; adiposity dimension) and Female Fit Body Scale (FFITBS; muscularity dimension).

Methods

One hundred and fifty-two women in the United Kingdom rated which body figure best represented their current and ideal body, completed the Eating Disorder Examination Questionnaire (EDE-Q 6.0), and their body composition was measured. During re-test, the EDE-Q 6.0 and Drive for Muscularity Scale (DMS) were completed.

Results

Both the FBS and the FFITBS were found to be valid and reliable, and distinct types of body dissatisfaction were identified. Higher EDE-Q scores corresponded with greater body dissatisfaction scores on both the FBS and FFITBS. Thin-ideal (FBS) and larger/muscularity-ideal (FFITBS) body dissatisfaction predicted higher scores on the DMS. The muscularity scale (FFITBS) uniquely revealed that 28% of participants indicated body dissatisfaction toward the larger-muscularity-ideal.

Conclusions

Results reveal distinct dimensions of body dissatisfaction. These new, validated scales may be utilized to quickly identify eating disorder risk in women as a preventative assessment for clinicians and inform female-focused body-image and eating disorder research.

Male Figural Rating Scales: A Critical Review of the Literature

Figural rating scales are tools used to measure male body dissatisfaction. The present review aimed to examine the design and psychometric properties of male figural rating scales and make recommendations based on findings. Relevant databases were systematically searched for studies that had developed and validated male figural rating scales. Twenty studies were included in this review. Figural rating scales differed in terms of the number of images represented and type of stimuli used (hand-drawn silhouettes, hand-drawn figures, computer-rendered figures, and photograph figures). Reliability and validity evidence varied greatly in strength across all scales. Four of the 20 scales included a correlational analysis between figural rating scale scores and eating disorder symptoms. Results showed the moderate to high positive correlations between eating disorder symptoms and figural rating scale perceived and index scores, suggesting that figural rating scales are sensitive to detecting eating disorder symptoms. Ideally, male figural rating scales should show strong validity and reliability, include variations in both body fat and muscularity, utilise realistic body stimuli, and be interval scales. No existing male figural rating scale meets these criteria. However, this review identifies five figural rating scales that meet the majority of the recommended criteria.

Examining University Men's Psychobiological and Behavioral Response-Recovery Profile From a Social-Evaluative Body Image Threat

Negative body image, which often results from social-evaluative body image threats, is common in young men and related to many harmful outcomes. Using social self-preservation theory (SSPT), the present study investigated the psychobiological (i.e., shame and cortisol) and behavioral (e.g., submission) response-recovery profile to a social-evaluative body image threat in university men. Participants (N = 69; M_age = 20.80 years, SD = 1.84) were randomly assigned to a high-threat (n = 34) or low-threat condition (n = 35). Men in the high-threat condition reported greater post-threat body shame, had greater post-threat cortisol levels, and exhibited more shame-relevant behaviors than men in the low-threat condition. There were no significant differences between conditions for body shame or cortisol at the final post-threat time point (after resting for 30 min). These findings are consistent with SSPT and suggest that men respond to, and recover from, body image threats relatively efficiently.

The effect of perceived appearance judgments on psychological and biological stress processes across adulthood

Social self-preservation theory posits that stress is experienced when an aspect of an individual's identity has the potential to be negatively evaluated. Appearance is a central part of identity; however, little research has examined whether perceived appearance judgements are a source of social-evaluative stress. In addition, stress may be an explanatory link in the association between appearance perceptions and depressive symptoms. This study examined whether perceived appearance judgements were associated with increased stress and greater depressive symptoms among adults. Study 1 examined the associations between self-reported appearance judgements and cortisol stress responses in response to a laboratory stressor (Trier Social Stress Test) among 71 individuals aged 18-65. Study 2 assessed self-reported appearance judgements and depressive symptoms among 498 adults ages 18-65 via an online survey data collection. Appearance judgement was associated with a stronger cortisol response, higher self-reported stress, and greater depressive symptoms. Stress mediated all associations between appearance judgements and depressive symptoms and neither age nor gender moderated these associations. The findings suggest that appearance judgements contribute to psychological and biological stress processes and demonstrated that stress mediated the association between appearance judgements and depressive symptoms.

Muscle Talk Online and Impression Formation Based on Body Type: Comparisons Between Asian American and Caucasian American Males

This study aimed to investigate how individuals form impressions about the self-esteem and life satisfaction of a male who engages in muscle talk on Facebook. The study examined (a) how a target's body build and peer-generated comments influence observers' impression of him, and (b) how such influences might be moderated by the cultural backgrounds of observers (Asian Americans and European Americans). A mock-up Facebook profile page was created in which two factors were manipulated: the target's body build (muscular, average, and overweight) and peer-generated messages (muscle encouraging and muscle discouraging), creating six different conditions. Male college students ( N = 508) were randomly assigned to one of the conditions. After viewing a mock-up Facebook page online, participants completed an online questionnaire assessing their impressions of the target's self-esteem and life satisfaction. Results showed that a muscular target was perceived as possessing higher levels of self-esteem and life satisfaction. Observers rated the target as having higher self-esteem when the target received muscle-encouraging messages than when the target received muscle-discouraging messages. No cultural differences were identified. Findings suggest the existence of weight bias when forming psychological impressions of others online. Findings also confirmed the important role of peer-generated messages in the impression formation process online.

Personality, emotion-related variables, and media pressure predict eating disorders via disordered eating in Lebanese university students

PURPOSE

Disordered eating behaviors are on the rise among youth. The present study investigates psychosocial and weight-related variables as predictors of eating disorders (ED) through disordered eating (DE) dimensions (namely restrained, external, and emotional eating) in Lebanese university students.

METHODS

The sample consisted of 244 undergraduates (143 female) aged from 18 to 31 years (M = 20.06; SD = 1.67). Using path analysis, two statistical models were built separately with restrained and emotional eating as dependent variables, and all possible direct and indirect pathways were tested for mediating effects. The variables tested for were media influence, perfectionism, trait emotional intelligence, and the Big Five dimensions.

RESULTS

In the first model, media pressure, self-control, and extraversion predicted eating disorders via emotional eating. In the second model, media pressure and perfectionism predicted eating disorders via restrained eating.

DISCUSSION

Findings from this study provide an understanding of the dynamics between DE, ED, and key personality, emotion-related, and social factors in youth. Lastly, implications and recommendations for future studies are advanced.

The relationship between psychophysical body categorization performance and male body dissatisfaction

The present study compared the predictive relationship between various psychophysical indices of body categorization performance (Point of Subjective Equivalence (PSE), Just Noticeable Difference (JND) and Reaction Time (RT)) and male body dissatisfaction (Male Body Attitudes Scale (MBAS)) and eating disorder symptoms (Eating disorders examination questionnaire (EDE-Q)), with performance on a validated figure rating scale (Visual Body Scale for Men (VBSM)). Body Mass Index, body fat percentage, and fat free mass index were also measured. PSE was not as sensitive in predicting body dissatisfaction and eating disorder symptoms as the VBSM. JND and average RT were found to be sensitive predictors of body dissatisfaction and eating disorder symptoms across the 82 male participants. JND proved to be a better indicator of weight concern than the VBSM-M. Whilst the body categorization task offers new insights into the way body images may be processed by males with different levels of body dissatisfaction, the VBSM and the conventional self-report measures are likely to be clinically more efficacious at measuring body dissatisfaction.

Asessing the male body image: Spanish validation of two instruments

Despite the literature suggesting that body dissatisfaction is increasing among males, only few measures on specific body image concerns in men have been validated in Spanish male populations. The aim of this study was to reassess the factor structure of the Spanish versions of the Muscle Dysmorphic Disorder Inventory (MMDI) and the Adonis Complex Questionnaire (ACQ). A cross-sectional study was conducted among 298 Sport Sciences male students to examine: reliability, the factorial structure, and several evidences of validity -concurrent and convergent- of both scales. The questionnaires present adequate reliability. The three-factor structure proposed for the MMDI was replicated. Nevertheless, the confirmatory factor analysis supports a second-order factor structure for the ACQ instead of the three-factor structure proposed. Moreover, the MDDI shows greater association than ACQ with the variables studied. This study represents an advance in the use of adequate and reliable scales of body image tools in the Hispanic population.

Correlations between Repeated Use of Dry Sauna for 4 x 10 Minutes, Physiological Parameters, Anthropometric Features, and Body Composition in Young Sedentary and Overweight Men: Health Implications

Background

The effect of thermal stress on the physiological parameters of young overweight and sedentary men who sporadically use the sauna remains insufficiently investigated.

Aim

The aim of the study was to determine the effect of sauna bathing on the physiological parameters of young overweight, physically inactive men and to test the correlations between physiological parameters versus anthropometric features and body composition parameters.

Materials and Methods

Forty-five overweight and sedentary men aged 20.76±2.4 y were exposed to four sauna sessions of 10 minutes each (temperature: 90-91°C; relative humidity: 14-16 %) with four 5-minute cool-down breaks. Body composition was determined before sauna, and body mass and blood pressure were measured before and after sauna. Physiological parameters were monitored during four 10-minute sauna sessions.

Results

A significant (p<0.0001) increase in all analyzed physiological parameters was observed during four successive 10-minute sauna sessions. Heart rate, energy expenditure, blood pressure, and body mass loss were most strongly correlated with anthropometric parameters (body mass, body mass index, and body surface area) and body composition parameters (percent body fat, body fat mass, and visceral fat level). The 60-minute treatment resulted in a significant reduction in body mass (0.65 kg).

Conclusions

Repeated use of Finnish sauna induces significant changes in the physiological parameters of young sedentary overweight men, and these changes are intensified during successive treatments. Deleterious cardiovascular adaptations were most prevalent in men characterized by the highest degree of obesity and the largest body size.

How Does Variation in the Body Composition of Both Stimuli and Participant Modulate Self-Estimates of Men's Body Size?

When measured in units of body mass index (BMI), how much variation in men's self-estimates of body size is caused by i) variation in participants' body composition and ii) variation in the apparent muscle mass and muscle tone of the stimuli being judged? To address this, we generated nine sets of male CGI bodies representing low, mid, and high muscle mass rendered at low, mid, and high muscle tone, from 18.75 to 40 BMI_hse units. BMI_hse units in this study are estimates of BMI derived from calibration equations predicting BMI from waist and hip circumference, age, sex, height, and ethnicity in the Health Survey for England databases. Forty-five healthy adult men estimated their body size using a yes-no paradigm for each combination of muscle mass/tone. We also measured participants' body composition with Harpenden callipers and their body concerns with psychometric questionnaires. We show that stimulus variation in apparent muscle mass/tone can introduce differences up to ∼2.5 BMI_hse units in men's self-estimates of body size. Moreover, men with the same actual BMI, but different body composition, showed up to ∼5-7 BMI_hse unit differences in self-estimates of body size. In the face of such large errors, we advocate that such judgments in men should be made instead by simultaneously manipulating both the adiposity and the muscle mass of stimuli which are appropriately calibrated for body composition, so that the participant can match the body size and shape they believe themselves to have to the stimulus they see.

Factors associated with restrained eating and validation of the Arabic version of the restrained eating scale among an adult representative sample of the Lebanese population: a cross-sectional study

BACKGROUND

Previous research suggests that restrained eating is problematic in Lebanon and is associated with the occurrence of clinically diagnosed eating disorders. Because of the alarming prevalence and severity of these disorders, the aim of this study is to investigate factors that may contribute to restrained eating in adults among a representative sample of the Lebanese population.

METHODS

This is a cross-sectional study conducted between January and May 2018; 811 adult participants were enrolled from all Lebanese districts. The Dutch Restrained Eating scale was used to measure body disturbance. The factors that were assessed in the questionnaire were body dissatisfaction, self-esteem, perceived stress, anxiety, depression, emotion regulation, emotional eating and adult attachment styles.

RESULTS

The mean age of the participants was 27.59 ± 11.76 years, and included 66.5% females. In the absence of a cutoff value for the Dutch Restrained Eating scale, we took the median (2.6) as the cutoff value. The results showed that 391 (48.3%) had restrained eating. The Dutch Restrained Eating scale items converged over a solution of one factor that had an Eigenvalue over 1, explaining a total of 60.69% of the variance (Cronbach's alpha was high =0.928). The linear regression results, taking the Dutch restrained eating scale as the dependent variable, showed that being a female (Beta = 0.31), increased age (Beta = 0.01), higher body mass index (Beta = 0.01), an intermediate monthly income (Beta = 0.25), higher body dissatisfaction scores (Beta = 0.03), higher adult anxiety attachment style (Beta = 0.008), higher emotion regulation cognitive reappraisal facet (Beta = 0.01), feeling pressure from TV/magazine to lose weight (Beta = 0.45) and practicing sport activities (Beta = 0.41) were associated with higher restrained eating scores.

CONCLUSION

Our findings show that numerous factors are associated with restrained eating in the Lebanese community. They include body dissatisfaction, cognitive reappraisal, female gender, eating attitudes, social media pressure and adult attachment. Therefore, the development of prevention strategies directed at an improved body image perception and increasing knowledge about factors that might influence this body image and critical thinking regarding media images is warranted, with the ultimate goal of promoting healthier choices in the Lebanese population.

Explaining male body attitudes: the role of early peer emotional experiences and shame

PURPOSE

The current study tested a path model that examined the association between early emotional experiences with peers and male body attitudes and whether general feelings of shame and body-focused shame mediate this relationship, while controlling for the effect of body mass index.

METHODS

The sample comprised 241 men from the general community, aged from 18 to 60, who completed an online survey.

RESULTS

Correlation analyses showed that the recall of positive early emotional experiences with peers is inversely linked to shame and negative body attitudes. Path analysis results indicated that early emotional experiences with peers had a direct effect on external shame, and an indirect effect on male negative body attitudes mediated by external shame and body-focused shame. Results confirmed the plausibility of the tested model, which accounted for 40% of the variance of male body attitudes. Findings suggested that men who recall fewer positive early peer emotional experiences tend to perceive that they are negatively viewed by others and present more body image-focused shame experiences. This in turn seems to explain a negative self-appreciation of one's muscularity, body fat and height.

CONCLUSIONS

This study contributes to a better understanding of male body attitudes. Findings suggest that the link between early emotional experiences and male body attitudes may depend on the experience of shame feelings and, particularly, on the extent to which one's body image becomes a source of shame. These data support the relevance of addressing shame experiences when working with men with body image-related difficulties.

LEVEL OF EVIDENCE

Level V-cross-sectional descriptive study.

Distortions of perceived volume and length of body parts

We experience our body as a 3D, volumetric object in the world. Measures of our conscious body image, in contrast, have investigated the perception of body size along one or two dimensions at a time. There is, thus, a discrepancy between existing methods for measuring body image and our subjective experience of having 3D body. Here we assessed in a sample of healthy adults the perception of body size in terms of its 1D length and 3D volume. Participants were randomly assigned to two groups using different measuring units (other body part and non-body object). They estimated how many units would fit in a perceived size of body segments and the whole body. The patterns of length and volume misperception across judged segments were determined as their perceived size proportional to their actual size. The pattern of volume misperception paints the representation of 3D body proportions resembling those of a somatosensory homunculus. The body parts with a smaller actual surface area relative to their volume were underestimated more. There was a tendency for body parts underestimated in volume to be overestimated in length. Perceived body proportions thus changed as a function of judgement type while showing a similarity in magnitude of the absolute estimation error, be it an underestimation of volume or overestimation of length. The main contribution of this study is assessing the body image as a 3D body representation, and thus extending beyond the conventional 'allocentric' focus to include the body on the inside. Our findings highlight the value of studying the perceptual distortions "at the baseline", i.e., in healthy population, so as to advance the understanding of the nature of perceptual distortions in clinical conditions.

Visual Body Scale for Men (VBSM): Validation of a new figural rating scale to measure perceived-desired body discrepancy in men

OBJECTIVES

This study examined the psychometric properties of the Visual Body Scale for Men (VBSM), a new figural rating scale designed as a measure of male perceived-ideal body discrepancy.

METHODS

In Study 1, participants were 133 males who selected their perceived and desired bodies from the VBSM. Body composition, body dissatisfaction, eating disorder and depressive symptomatology were obtained. In Study 2, participants were 33 males who completed the VBSM and the Bodybuilder Image Grid (BIG). Study 2 aimed to compare the validity evidence of the VBSM to the BIG.

RESULTS

Both VBSM-Body Fat (VBSM-BF) and VBSM-Muscularity (VBSM-M) demonstrated sound test-retest reliability, convergent, concurrent, and discriminant validity evidence. Additionally, the VBSM demonstrated better sensitivity for detecting body fat-related body image and dissatisfaction when compared to the BIG.

CONCLUSION

The VBSM improves upon existing male figural rating scales in terms of image quality, includes both dimensions of a male body image, and demonstrates good psychometric properties.

Fear of Being Laughed at in Children and Adolescents: Exploring the Importance of Overweight, Underweight, and Teasing

Weight bias toward obese youths is often accompanied by the experience of psychological stress in those affected. Therefore, the fear of being laughed at (i.e., gelotophobia) in overweight children and adolescents can be rather serious. In four explorative studies, the importance of relative weight, self-awareness of weight (incl. satisfaction with weight), experiences of teasing and ridicule, as well as the role of social-evaluative situations in school were analyzed with regard to gelotophobia. In two online interviews of adults with pronounced gelotophobia (Study I: 102 English-speaking participants, Study II: 22 German-speaking participants) relating to reasons they assumed for their development of gelotophobia, there was evidence of injurious appearance-related experiences during childhood and adolescence. In Study III (75 Swiss adolescents) associations between the experience of weight-related teasing and mockery with overweight, self-perceptions of weight, and gelotophobia were analyzed. Especially in girls, overweight was associated with the experience of weight-related teasing and ridicule, which in turn was accompanied by gelotophobia. Study IV included 178 German adolescents who were asked to report their body image (“Do you think you are… too thin, just the right weight, or too fat?”). In addition, gelotophobia, teasing, BMI based on self-reports, and joy at school were measured. In particular, girls who felt too fat and boys who felt too thin reported teasing. Teasing was related to diminished joy at school and to gelotophobia. Among boys, underweight mediated by weight-related teasing contributed to gelotophobia. The results suggest that more research should be devoted to gelotophobia and the experience of weight-related teasing and mocking to better understand factors contributing to the well-being of children and adolescents with weight problems.

Weight/shape and muscularity concerns and emotional problems in adolescent boys and girls: A cross-lagged panel analysis

INTRODUCTION

The goal of the present study was to identify the prospective relations between weight/shape and muscularity concerns and emotional problems in adolescents.

METHODS

Self-report data of 966 German male and female adolescents were analyzed in a cross-lagged panel design.

RESULTS

Analyses of latent means revealed significant correlations between weight/shape concern and emotional problems as well as between muscularity concern and emotional problems in both genders. Moreover, weight/shape concern predicted emotional problems prospectively, but only in girls. Regarding muscularity concern, we could not find any prospective relation with emotional problems in boys or girls from the general population.

CONCLUSIONS

It is assumed that as appearance is highly relevant for the self-concept in girls, concerns about the look might promote emotional problems. Thus, weight/shape concern should be addressed in the prevention of emotional problems in adolescent girls, whereas further research is necessary investigating the contribution of muscularity concern in this context.

Youth's social network structures and peer influences: study protocol MyMovez project - Phase I

Background

Youth are an important target group for social network interventions, because they are particularly susceptible to the adaptation of healthy and unhealthy habits and behaviors of others. They are surrounded by ‘social influence agents’ (i.e., role models such as family, friends and peers) that co-determine their dietary intake and physical activity. However, there is a lack of systematic and comprehensive research on the implementation of a social network approach in health campaigns. The MyMovez research project aims to fill this gap by developing a method for effective social network campaign implementation. This protocol paper describes the design and methods of Phase I of the MyMovez project, aiming to unravel youth’s social network structures in combination with individual, psychosocial, and environmental factors related to energy intake and expenditure. In addition, the Wearable Lab is developed to enable an attractive and state-of-the-art way of collecting data and online campaign implementation via social networks.

Methods

Phase I of the MyMovez project consists of a large-scale cross-sequential cohort study (N = 953; 8-12 and 12-15 y/o). In five waves during a 3-year period (2016-2018), data are collected about youth’s social network exposure, media consumption, socialization experiences, psychological determinants of behavior, physical environment, dietary intake (snacking and drinking behavior) and physical activity using the Wearable Lab. The Wearable Lab exists of a smartphone-based research application (app) connected to an activity tracking bracelet, that is developed throughout the duration of the project. It generates peer- and self-reported (e.g., sociometric data and surveys) and experience sampling data, social network beacon data, real-time physical activity data (i.e., steps and cycling), location information, photos and chat conversation data from the app’s social media platform Social Buzz.

Discussion

The MyMovez project - Phase I is an innovative cross-sequential research project that investigates how social influences co-determine youth’s energy intake and expenditure. This project utilizes advanced research technologies (Wearable Lab) that provide unique opportunities to better understand the underlying processes that impact youths’ health-related behaviors. The project is theoretically and methodologically pioneering and produces a unique and useful method for successfully implementing and improving health campaigns.

New Body Scales Reveal Body Dissatisfaction, Thin-Ideal, and Muscularity-Ideal in Males

The aim of the current study was to develop, test, and retest two new male body dissatisfaction scales: The Male Body Scale (MBS; consisting of emaciated to obese figures) and the Male Fit Body Scale (MFBS; consisting of emaciated to muscular figures). These scales were compared to the two most commonly used visually based indices of body dissatisfaction (Stunkard Figure Rating Scale, SFRS; and Somatomorphic Matrix, SM). Male participants rated which body figure on each scale most represented their current figure, then their ideal figure, and then rated which one of the three scales (MBS, MFBS, and SFRS) best represented their current and ideal body overall. Finally, they completed the Drive for Muscularity Scale (DMS), the Eating Disorder Examination Questionnaire (EDE-Q 6.0), and their actual body composition was calculated. This was followed by a retest and manipulation check 2 to 6 weeks later. Participants’ actual body mass index, fat- and muscularity-percentage were all highly related to their current body figure choice, and both new scales were consistently valid and more reliable between test and retest than the SFRS and SM body dissatisfaction scores. Importantly, each scale was sensitive to different types of body dissatisfaction within males. Specifically, the MBS revealed that males’ desire for the thin-ideal significantly corresponded to higher eating disorder tendencies as identified by EDE-Q 6.0 scores, while the MFBS revealed much higher body dissatisfaction toward the larger, muscularity-ideal, predicting higher drive for muscularity as identified by DMS scores. Results validated the new scales, and inform male-focused eating disorder research.

Brazilian Photographic Figure Rating Scale for Men: Psychometric Investigation

As a follow-up to an earlier study from this research group involving women, this study examined the reliability and validity of the Brazilian Photographic Figure Rating Scale for Men (BPFRS-M) for evaluating men's body perception and dissatisfaction. In both versions of the Brazilian Photographic Figure Rating Scale (BPFRS), respondents viewed eight photographic images (seven distorted and one accurate) of themselves in standard poses and then offered self-ratings. In both versions, 10 experts assessed content validity and demonstrated high agreement (defined by ratings of 4-5 on a 5-point scale) that BPFRS items measured underlying constructs: and experts showed high (>70%) interrater agreement. For this version, participants were 149 Brazilian men (Mean = 22.4; SD = 2.7 years). Pearson correlations demonstrated convergence between the BPFRS-M and two related scales of men's body image. Positive correlations ( p = .0001) were found between actual and respondent-perceived body mass index (BMI). Test-retest and Kappa Index confirmed temporal stability. The BPFRS-M can accurately and reliably assess body perception and dissatisfaction in young men.

Affective predictors of the severity and change in eating psychopathology in residential eating disorder treatment: The role of social anxiety

Despite evidence documenting relationships between eating disorder (ED) psychopathology, depression, and anxiety, little is known regarding how social anxiety is related to ED symptoms in treatment. Therefore this study examined associations between depression, general anxiety, social anxiety, and ED psychopathology at the beginning and end of treatment (EOT) among patients (N = 380) treated in a residential ED program. Participants completed measures of ED psychopathology and affective variables. Higher depression and general anxiety, but not social anxiety, were related to higher ED psychopathology at baseline. However, social anxiety emerged as a unique predictor of ED psychopathology at EOT such that participants with higher social anxiety evidenced less improvement in ED psychopathology. Findings suggest that social anxiety has specific relevance to treatment in EDs, which may reflect shared mechanisms and underlying deficits in emotion regulation.

Perceptual body image and the relationship with weight control across the adult lifespan by sex in Koreans

Background

This study aimed to investigate perceptual body image and the relationship between perceived body image (PBI) and weight control differentiated according to obesity categories across the adult lifespan by sex among Koreans.

Methods

We analyzed data on 10 198 adults aged 25 or older from the Korean National Health and Nutrition Examination Survey of a nationally representative sample of non-institutionalized Koreans.

Results

Significant discordance between PBI and body mass index (BMI) or waist circumference (WC) was found in all age groups in both sexes, and the discordance for obesity grew more severe with age. Linear associations between PBI and BMI or WC were found in normal weight and obese groups in all age groups in both sexes, with relatively greater BMI or WC differences for PBI found in obese men aged ≤64 or ≤44, respectively, and obese women of all ages or aged ≥75, respectively, compared to normal weight. Obese women aged ≥65 (BMI) or ≥75 (WC) and obese men in the 45-54 and 65-74 age groups (BMI and WC) had significant association between PBI and weight control.

Conclusions

Interventions regarding accurate body size perception should be prioritized for obese women aged ≥65 or ≥75 and for obese men aged 45-54 and 65-74.

Body-scaled action in obesity during locomotion: Insights on the nature and extent of body representation disturbances

OBJECTIVE

Conscious perception of our own body, also known as body image, can influence body-scaled actions. Certain conditions such as obesity are frequently accompanied by a negative body image, leaving open the question if body-scaled actions are distorted in these individuals.

METHODS

To shed light on this issue, we asked individuals affected by obesity to process dimensions of their own body in a real action: they walked in a straight-ahead direction, while avoiding collision with obstacles represented by door-like openings that varied in width.

RESULTS

Participants affected by obesity showed a body rotation behavior similar to that of the healthy weighted, but differences emerged in parameters such as step length and velocity.

CONCLUSION

When participants with obesity walk through door-like openings, their body parts rotation is scaled according to their physical body dimensions; however, they might try to minimize risk of collision. Our study is in line with the hypothesis that unconscious body-scaled actions are related to emotional, cognitive and perceptual components of a negative body image.
