Gender Differences in Affective and Evaluative Responses to Experimentally Induced Body Checking of Positively and Negatively Valenced Body Parts

Body checking (BC) is defined as behavior aimed at gaining information on body shape, size, or weight. Besides its occurrence as a transdiagnostic symptom in eating disorders (EDs), BC is widespread in non-clinical populations. It is associated with body dissatisfaction and the development of body image disturbances and ED. Males and females differ in terms of body dissatisfaction and associated BC strategies. However, the question of a gender-related intensity of negative affect and state body satisfaction as reactions to BC remains open. Therefore, the present experimental study aimed to examine gender differences in affective and evaluative responses to BC. We tested n = 60 women and n = 60 men in a crossover design, implementing two experimental conditions and one control condition. In the negative body checking condition (NBC), participants received standardized instructions to check negatively valenced body parts. In the positive body checking condition (PBC), by contrast, participants were asked to check positively valenced body parts. The control condition (CBC) consisted of playing a computer game. Before and after checking of one’s own body, participants rated negative body-related affect, i.e., guilt, shame, and disgust, and state body satisfaction. The results indicate that both NBC and PBC led to an increase in negative affect for men and women. Eating pathology predicted negative affect after checking in NBC for both genders. Men reported a significantly higher state body satisfaction in all conditions, whereas only women showed decreased body satisfaction in NBC. These findings suggest that BC of any body part (i.e., positively or negatively valenced) leads to increased negative affect for both genders. Eating pathology significantly influences the affective responses to BC for both genders. Changes in state body satisfaction, however, only occur in females. An explanation might be that men generally report higher body satisfaction, resulting in a more stable body image. Females and males with pathological eating behavior seem to be more vulnerable to changes in negative affect. As negative affect is equally increased after NBC and PBC for both genders, BC might play a central role in the maintenance of body image disturbances in males and females

Gender Differences in Body Evaluation: Do Men Show More Self-Serving Double Standards Than Women?

Generally speaking, compared to women, men are less dissatisfied with their own body and consider themselves to be better-looking and less overweight. So far, however, it is unclear whether these divergent body ratings arise from the application of double standards. With the present study, we examined whether men apply different standards to their own body than to other men’s bodies and whether they differ from women in this regard. To this aim, we presented n = 104 women and n = 93 men with pictures of thin, average-weight, overweight, athletic and hypermuscular male and female bodies on a computer screen. To manipulate identification, we showed the bodies of the respective participant’s gender once with the participant’s own face and once with the face of another person. Identity cues, such as faces, might activate different body schemata, which influence body ratings and thus lead to the application of double standards. Participants were instructed to rate their emotional reaction to the bodies according to valence and arousal, and to rate the bodies with respect to attractiveness, body fat, and muscle mass. The application of double standards was determined by calculating the difference between the rating of a body presented with the participant’s face and the rating of the same body presented with another person’s face. Both women and men showed self-deprecating double standards in valence, body attractiveness, body fat and muscle mass for the overweight body. Men also revealed self-deprecating double standards for the thin, average-weight and hypermuscular bodies, but evaluated the athletic body as more attractive and with a higher positive feeling when it was presented with their own face. Women did not show any self-serving double standards and showed fewer self-deprecating double standards than men. The results indicate that men devalue non-ideal bodies and upvalue ideal bodies when they are self-related, whereas women more rate in a fair-minded manner. Thus, in contrast to women, an advantage for men may be that they are able to self-enhance in the case of desirable bodies. This ability to self-enhance regarding desirable features might be beneficial for men’s self-worth and body satisfaction

The role of body image disturbance in the onset, maintenance, and relapse of anorexia nervosa:A systematic review

Body image disturbance is an important feature of Anorexia Nervosa (AN). Some researchers have argued that body image disturbance is not just a symptom of AN, but plays a causal role in the development, persistence, and relapse of AN. Our aim was to systematically review the existing empirical evidence concerning the role of the cognitive-affective, perceptual, and behavioral components of body image disturbance in AN. 46 studies fulfilled eligibility criteria reporting about 4928 participants with AN. There is some evidence suggesting that body image disturbance is related to the course of AN. However, experimental studies were missing and operationalizations of body image constructs and AN outcome measures varied greatly across studies. Therefore, on the basis of the available empirical data, it remained unclear whether body image disturbance is indeed a causal risk factor for AN. For future studies, it is crucial to use more consistent terminology and more specific and precise definitions of body image constructs as well as experimental designs, adequately powered samples, and well-validated measures. Altogether, this would set the stage to generate the high-quality data that are necessary to clarify the role of body image disturbance in the onset, maintenance and relapse of AN

Eating disorders and their putative risk factors among female German professional athletes.

This study examines putative non-sport-specific and sport-specific risk factors for eating disorders (ED) among groups of professional female athletes versus non-athletes. In detail, societal pressure to be thin, its internalisation, body dissatisfaction, sports pressure and early specialisation were investigated. The cross-sectional study included 46 aesthetic and 62 ball game sports athletes, and 108 age-matched non-athletes. Study methods comprised a clinical interview to detect ED and questionnaires. More athletes from aesthetic (17%) than from ball game sports (3%) and non-athletes (2%) suffered from ED. Aesthetic sports athletes did not differ from non-athletes in non-sport-specific factors but obtained higher levels than ball game sports athletes in sport-specific variables (p < .01). All factors together accounted for 57.3% of variation in disordered eating, with sports pressure and body dissatisfaction as significant predictors. The results confirm ED risk for German aesthetic athletes and indicate the importance of sports pressure and body dissatisfaction in explaining athletes' vulnerability.Swiss Anorexia Nervosa Foundation Ruhr‐University Bochum Olympic Support Centre Westphali

Time to make a change:A call for more experimental research on key mechanisms in anorexia nervosa

Anorexia nervosa (AN) is a life‐threatening eating disorder, characterised by persistent pathological weight loss behaviours and an intense fear of weight gain and food consumption. Although there is an abundance of scientific theories on the neurobiological, psychological and sociocultural factors thought to be involved in the maintenance of AN, there is little experimental research testing these ideas. The need for theory firmly grounded in empirical evidence becomes strikingly clear when we consider that current treatments for patients with AN are limited in their effectiveness, and relapse after treatment is common

Development and initial psychometric evaluation of the Body Image Matrix of Thinness and Muscularity – Female Bodies

Background: Despite evidence that thinness and muscularity are part of the female body ideal, there is not yet a reliable figure rating scale measuring the body image of women which includes both of these dimensions. To overcome this shortcoming, the Body Image Matrix of Thinness and Muscularity - Female Bodies (BIMTM-FB) was developed. Methods: The objective of this study is to analyze the psychometric properties of this measure. N = 607 non-clinical women and N = 32 women with eating disorders answered the BIMTM-FB as well as instruments assessing eating disorder symptoms and body image disturbance in order to test the convergent validity of the BIMTM-FB. To assess test-retest reliability, a two-week interval was determined. Results: The results indicated that the body-fat dimension of the BIMTM-FB correlates significantly with the Contour Drawing Rating-Scale, the Drive for Leanness Scale (DLS) and the Body Appreciation Scale, while the muscularity dimension of the BIMTM-FB was significantly associated with the DLS and the Drive for Muscularity Scale, proving the convergent validity of the BIMTM-FB. High coefficients of test-retest reliability were found. Moreover, the BIMTM-FB differentiated between the clinical sample and the non-clinical controls. Conclusions: The BIMTM-FB is a figure rating scale assessing both thinness and muscularity as part of the female body ideal. Due to its high reliability and validity, the BIMTM-FB can be recommended in research and practice
