Eating disorders are more common in females than in males and are believed to be caused, in part, by biological and hormonal factors. Digit ratio or 2D:4D (the ratio of the 2nd to the 4th digit) is considered to be a proxy for prenatal testosterone (PT) and prenatal oestrogen (PE) exposure. However, how 2D:4D may be related to type of eating pathology is unknown. The relationship between 2D:4D and eating disorder diagnosis was investigated in recovered and currently eating disordered (n = 31) and control (n = 99) women. Mean 2D:4D ratio was significantly lower (indicating higher levels of PT and lower levels of PE) in anorexic (AN) compared to bulimic (BN) women, with controls intermediary. In eating disordered women, 2D:4D was positively and significantly related to current weight, lowest weight and current BMI, with strongest associations for right 2D:4D. Among women, low 2D:4D is related to AN and high 2D:4D to BN, suggesting a differential causal influence of prenatal sex hormones on later eating pathology.  相似文献

Restrained and binge eating are related to depressive symptomatology in women; we examined the role of ruminative coping in this association. Sample participants (N?=?329) were female college students in the Midwestern U.S. who completed a health behaviors survey. Multiple regression models examining the pathway between eating (restrained and bingeing, respectively) and depressive symptoms were tested; ruminative coping was examined as the mediator in all models. Models in which dysregulated eating predicted depressive symptoms explained more variance than those testing the reverse pathway. Ruminative coping fully mediated the association between restrained eating and depressive symptoms and partially mediated the association between binge eating and depressive symptoms. Findings suggest ruminative coping is a mechanism linking disordered eating and depressive symptoms.  相似文献

Sociocultural norms pertaining to an ideal of thinness for women likely play a role in the development and maintenance of disturbance in body image, and by extension, disordered eating. However, competing norms associated with feminism may buffer women from pressures associated with achieving the thin ideal. The present study explored the relationship between feminist ideology, empowerment, and self-efficacy relative to body image and eating behavior with a sample of U.S. undergraduate women (N = 318) attending a southeastern U.S. mid-sized university. In planned hierarchical multiple regression analyses, endorsement of feminist ideology predicted perceptions of positive body image, but did not appear to predict disordered eating. Self-efficacy emerged as a robust predictor of positive body image and lower disordered eating even after controlling for perceptions of personal empowerment and feminism. Results, although limited by correlational data, suggest that self-efficacy may protect college-aged women from disordered eating and negative body image.  相似文献

We predicted that an expectancy of acquiring a feared fat self and an expectancy of acquiring a hoped-for thin self both mediate the impact of body size on women's body esteem. We also predicted that the mediating pathway through the feared fat self would be stronger than that through the hoped-for thin self. A community sample of 251 women reported their age, height, weight, and completed measures of body esteem and expectancy perceptions of acquiring the feared fat and hoped-for thin selves. Bayesian Structural Equation Modeling (SEM) demonstrated that expectancies about the feared fat self and about the hoped-for thin self mediated the relationship between body size and body esteem. Bayesian SEM also revealed that the pathway through the feared fat self was stronger than that through the hoped-for thin self. Implications for future research and the development of eating pathology are discussed.  相似文献

Sociocultural models of disordered eating lack comprehensive explanations as to how thin ideal internalization leads to body dissatisfaction. This study examined two social psychological theories as explanations of this relation, namely social comparison and objectification theories, in a sample of 265 women attending a Southeastern university. Social comparison (both general and appearance-related) and body surveillance (the indicator of objectification) were tested as mediators of the relation between thin ideal internalization and body dissatisfaction using bootstrapping analyses. Results indicated that body surveillance was a significant specific mediator of this relation; however, neither operationalization of social comparison emerged as such. Results serve to elaborate upon the sociocultural model of disordered eating by providing a more comprehensive understanding of the processes by which thin ideal internalization manifests itself in body dissatisfaction. The current findings also highlight the importance of targeting body surveillance in clinical settings.  相似文献

Disordered eating in children is a major public health concern, as it is precursor to clinical eating disorders and obesity. However, little is known about the potential causes of child disordered eating. The current study examined marital conflict as a predictor of disordered eating in a sample of children aged 5–12 years, from the perspective of emotional security theory. Ninety five children and their parents in the Southeast United States participated in the study. We found that marital conflict was associated with higher levels of restrained eating, emotional eating and external eating behaviors controlling for demographics and parental feeding practices. Further, we examined the possible pathways between marital conflict and child disordered eating and found that marital conflict was related to greater child emotional insecurity about the family, which was associated with greater child anxiety, which were then related to disordered eating. In addition to serving as a secondary pathway linking emotional insecurity to child disordered eating, anxiety also significantly directly mediated the association between marital conflict and all three types of disordered eating: restrained eating, emotional eating and external eating in children. Next we examined if parental feeding practices (food monitoring, food restriction and parental pressure to eat) moderate the relation between marital conflict and child disordered eating. Parental pressure to eat was negatively associated with child disordered eating under higher marital conflict. The current study highlights the importance of marital conflict and child emotional security as precursors of child disordered eating.  相似文献

Unhealthy eating attitudes and poor body esteem often lead to adverse outcomes (e.g., eating disorders). Prior research has identified two risk factors for these outcomes--endorsement of the superhero ideal and maladaptive perfectionism--and has suggested that these factors may interact to predict unhealthy eating attitudes and body esteem. The current study examined the interaction between the superhero ideal and maladaptive perfectionism as predictors of unhealthy eating attitudes and body esteem among 161 12- to 14-year-olds (74 males, 87 females). Maladaptive perfectionism moderated the relation between endorsement of the superhero ideal and unhealthy eating attitudes for girls only, such that endorsement of the superhero ideal was significantly associated with unhealthy eating attitudes only for adolescents with high levels of maladaptive perfectionism. The moderation model was not significant for body esteem. Prevention strategies should focus on reducing endorsement of the superhero ideal when there are high levels of maladaptive perfectionism.  相似文献

Despite numerous body size estimation studies, it cannot be concluded that the disturbance of body image in anorexia nervosa (AN) is specifically one of the visual body images.We adopted a visual imagery method, the Distance Comparison task, to enable across-population testing of differences in visual body image with respect to shape. Participants were asked to mentally scan across two body widths (e.g. hips and shoulders) and to decide as quickly as possible which one was longer or shorter. If the mental representation accessed to make such comparisons is visual, an inverse relation would be expected between RT and distance difference on the body to be judged (i.e. actual difference in size between the two body widths), with accuracy increasing with increasing distance difference. Females with high body shape concern (scoring high on the Body Shape Questionnaire: BSQ, n = 23) were compared to females with low body shape concern (scoring low on the BSQ, n = 19).RT and distance differences on the body demonstrated standard distance differences effects: RT increased and accuracy decreased with decreasing distance differences on the body. Groups differed with respect to accuracy, in that females high on body shape concern were significantly less accurate than females low on body shape concern when making evaluations involving small (?9 cm) differences, which implies a less appropriate visual image of the own body in the former group. With respect to the relation between RT and body distance difference, on the other hand, there were no differences between groups. We concluded that evaluations of own body size employ visual imagery and that the distance comparison task holds promise for the assessment of visual disturbances in body image in clinical populations.  相似文献

This study examined a sociocultural model of the influence of parental comments on body shape and eating concerns among males and females. Questionnaires were completed by 338 undergraduates. Participants reported levels of perceived parental comments, internalization of media ideals, appearance comparison, body dissatisfaction, drive for thinness and bulimia. Results revealed that, regardless of gender, internalization and appearance comparison only partially mediated the relationship between parental comments and the outcome variables. The final model for females explained a larger proportion of the variability in body shape and eating concerns than in males, with positive and negative parental comments directly related to body dissatisfaction and through it to eating outcomes. In males, only negative comments were directly related to body dissatisfaction. These findings highlight the role of parental influences in sociocultural models of the development of body dissatisfaction and eating concerns, and the gender-specific patterns of sociocultural influence.  相似文献

This study examined the role of media body comparison as a mediator of the relationships between psychological factors and sociocultural pressures to be thin and body dissatisfaction in both females and males. Participants were 1,386 females (mean age = 19.37 years) and 1,130 males (mean age = 19.46) from diverse backgrounds who completed a self-report questionnaire. Path analysis was used to test a cross-sectional model in which media body comparison mediated the impact of self-esteem, depressive mood, parent dieting environment, friend dieting, TV exposure, magazine message exposure, weight teasing and body mass index (BMI) on body dissatisfaction. In females, media body comparison partially or fully mediated relationships between self-esteem, depressive mood, friend dieting, magazine message exposure and BMI, and body dissatisfaction. In males, media body comparison was not a significant predictor of body dissatisfaction. This research particularly highlights the need to further examine processes that are involved in the development of body dissatisfaction in males.  相似文献

Social comparison (i.e., body, eating, exercise) and body surveillance were tested as mediators of the thin-ideal internalization-body dissatisfaction relationship in the context of an elaborated sociocultural model of disordered eating. Participants were 219 college women who completed two questionnaire sessions 3 months apart. The cross-sectional elaborated sociocultural model (i.e., including social comparison and body surveillance as mediators of the thin-ideal internalization-body dissatisfaction relation) provided a good fit to the data, and the total indirect effect from thin-ideal internalization to body dissatisfaction through the mediators was significant. Social comparison emerged as a significant specific mediator while body surveillance did not. The mediation model did not hold prospectively; however, social comparison accounted for unique variance in body dissatisfaction and disordered eating 3 months later. Results suggest that thin-ideal internalization may not be “automatically” associated with body dissatisfaction and that it may be especially important to target comparison in prevention and intervention efforts.  相似文献

The current study was conducted to investigate the relationships between body size estimations and disordered eating symptomatology. The method of constant stimuli was used to derive three measures of self-perceived body size in 93 women: (1) accuracy of body size estimations (body image distortion); (2) sensitivity in discriminating body size within blocks of trials (body image sensitivity); and (3) variability in making body size estimations between blocks of trials (body image variability). Participants also completed measures of disordered eating. Although body image distortion correlated with dietary restraint and eating concern, body image variability accounted for additional variance in these variables, as well as variance in binge eating. The relationships involving body image variability were found to be mediated by body dissatisfaction and internalization of the thin ideal. Together, these results are consistent with the proposition that body image variability is a significant factor in disordered eating.  相似文献

This study examined the relations between susceptibility for thin ideal media and restrained, emotional and external eating, directly and indirectly through body dissatisfaction. Thin ideal media susceptibility, body dissatisfaction and eating styles were measured in a sample of 163 female students. Structural equation modelling was used for analyses, controlling for BMI. Higher susceptibility for thin ideal media was directly related to higher scores on all eating styles, and indirectly related to higher restrained and emotional eating through elevated levels of body dissatisfaction. So, thin ideal media susceptibility was not only related to restraint through body dissatisfaction, but also directly. Emotional eaters might be more vulnerable for negative affect, whereas external eaters might be more sensitive to external cues in general.  相似文献

The present study aimed to investigate whether perfectionism mediates the association between obsessive–compulsive (OC) and eating disorder (ED) symptoms. Analyses were conducted using data collected among a national sample of eating disordered women diagnosed with BN or a subclinical variant of BN (N = 204). Each participant completed a series of self-report inventories on perfectionism, as well as OC, ED, and depressive symptoms. Higher ED symptoms were significantly associated with greater levels of perfectionism (p < .01) and OC symptoms (p < .05). As hypothesized, perfectionism significantly mediated the relationship between ED and OC symptoms, controlling for depression. Findings indicate that perfectionism may be considered a shared etiological or phenomenological factor in ED and OC symptoms.  相似文献

The present study examined the links between dispositional mindfulness, body comparison, and body satisfaction. It was expected that mindfulness would be associated with less body comparison and more body satisfaction. Two models were tested: one exploring body comparison as a mediator between mindfulness and body satisfaction and an alternative model exploring mindfulness as a mediator between body comparison and body satisfaction. In an online survey, 1287 Dutch women answered questions concerning dispositional mindfulness, body comparison, and body satisfaction. Results showed that body comparison was related negatively to both dispositional mindfulness and body satisfaction, whereas the two latter variables were related positively. Body comparison partially mediated the relation between mindfulness and body satisfaction. However, a stronger indirect effect was noted in the alternative model, where mindfulness partially mediated the link between body comparison and body satisfaction.  相似文献

We examined self-objectification in relation to well-being, and the potential moderating versus mediating role of body image coping strategies (appearance fixing, avoidance, positive rational acceptance). Undergraduate women from southern Ontario, Canada (Sample 1, n?=?104; Sample 2, n?=?314) completed measures of depression, disordered eating attitudes, subjective well-being, and body-image coping. Self-objectification was related to greater depression, disordered eating attitudes, and lower subjective well-being. A two-stage mediation model was supported: Body shame and body image coping strategies (appearance fixing and avoidance) partially mediated the associations between self-objectification and outcomes; appearance fixing and avoidance partially mediated the associations between body shame and outcomes. Body image coping strategies did not moderate any of the relations between body shame and outcomes.  相似文献

Objective: To examine the relationship between Positive and Negative Perfectionism and Social Physique Anxiety (SPA) and the extent to which these two variables predict disturbed eating attitudes in male and female elite athletes.Design: Cross-sectional survey.Method: Athletes (n=316) completed measures of Positive and Negative Perfectionism, SPA, disordered eating and social desirability. Zero- and first-order (partial) correlations were examined to determine the relationship between Positive and Negative Perfectionism and SPA. Hierarchical regression analyses were used to examine how two individual difference variables, perfectionism and SPA, relate and contribute to disordered eating.Results: For both male and female athletes, Negative Perfectionism was significantly related to SPA. For males, Positive Perfectionism made a small, yet significant, contribution (i.e. 6%) in predicting disturbed eating attitudes. For females, Negative Perfectionism and SPA uniquely and in combination significantly contributed 41% of the variance in the prediction of disturbed eating attitudes.Discussion: These findings suggest that Negative Perfectionism is strongly linked with SPA and that, in females, SPA is an additional psychosocial variable to consider in the relationship between Negative Perfectionism and disordered eating.  相似文献

This research explored the relative contributions of subjective perceptions of body weight and body shape/proportion, as well as objective measures of body mass index (BMI) and waist-to-hip ratio (WHR) to disordered eating, exercise involvement, and body image. One hundred and fifty-eight female university students completed questionnaires and provided body measurements for this study. Although an interaction between BMI and WHR was found for some measures (i.e., Eating Disorder Examination Questionnaire total and subscale scores), results indicated that BMI was consistently the better objective predictor of disordered eating and body image. Subjective perceptions of body weight and, to a lesser extent, body shape, were found to account for the greatest proportion of variance in the dependent measures (disordered eating, body esteem, and body dissatisfaction). Overall, these results offer more support for sociocultural theories emphasizing the importance of thinness for women, than evolutionary theories emphasizing the role of WHR.  相似文献

Talk about physical appearance and body image is common among young women. We investigated how body talk (negative, positive/self-accepting, and co-ruminative) is related to body image, body-related cognitive distortions, disordered eating, psychological adjustment, and friendship quality via hierarchical regression analyses (controlling for social desirability and body mass index). In a sample of young adult women (N = 203), negative body talk was, as predicted, negatively related to body satisfaction and self-esteem and positively related to appearance investment, body-related cognitive distortions, disordered eating, and depression, but not friendship quality. Self-accepting/positive body talk was negatively related to body-related cognitive distortions and positively related to body satisfaction, self-esteem, and friendship quality. Body-related co-rumination demonstrated adjustment trade-offs, being related to body-related cognitive distortions, disordered eating, and higher friendship quality. Results indicated no advantage to negative body talk, both individual and relationship benefits from positive/self-accepting body talk, and mixed outcomes for body-related co-rumination  相似文献

Although there has been considerable empirical support for Objectification Theory ( Fredrickson & Roberts, 1997 ), findings have been mixed regarding self-objectification's relationship to interoceptive awareness, an awareness of one's internal physical and emotional states. We examined whether interoceptive awareness mediated the relationship between self-objectification and disordered eating attitudes, exploring more specifically the relative contributions of difficulties recognizing feelings of hunger and satiety versus emotions. College women ( N = 195) completed measures assessing self-objectification, interoceptive awareness, awareness of emotions, and disordered eating attitudes. Self-objectification correlated significantly more strongly with interoceptive awareness when internal cues about hunger and satiety were assessed. The relationship between self-objectification and disordered eating attitudes was partially mediated by interoceptive awareness. Results revealed that interoceptive awareness may best be captured by a measure that includes lack of awareness of both hunger and satiety and emotional states. Research and clinical implications of these findings are discussed.  相似文献
