Review of the evidence for a sociocultural model of bulimia nervosa and an exploration of the mechanisms of action

Cultural representations of thinness in women, redux: Playboy magazine's depiction of beauty from 1979 to 1999

Playboy's portrayal of the male ideal of feminine beauty, in terms of overall body size, percent normative weight, and waist-to-hip ratios (WHRs), was analyzed for the years 1979-1999. Trends were examined through body measurements obtained from Playboy centerfolds. Results reveal a continuation of the low body mass index (BMI) found in the Playmates by earlier studies; however, for the 21 years examined, the trend towards increasing thinness seems to have stabilized and may have begun to actually reverse. There was also an increase in the centerfolds' WHRs over the 21-year time period. Overall, the results support the continued valuing in American society of a thin ideal for women; while the images of beauty have become somewhat heavier over the 21-year period reviewed, the Playmates remain markedly below weights normative for their age group.

Body image attitudes and concerns among indigenous Fijian and European Australian adolescent girls

Research on body image has primarily been conducted among Western women who highly value the thin ideal body size. There has been limited research that has examined body image attitudes among Fijian adolescent girls who are exposed to both traditional sociocultural pressures that promote a larger body size and Western pressures that promote slimness. Using in-depth semi-structured interviews, we examined the factors associated with body image attitudes and concerns among a sample of 16 indigenous Fijian and 16 European Australian adolescent girls aged between 13-18 years. An inductive analysis of girls' responses indicated that both groups of girls experienced body image concerns including body dissatisfaction, a preference for thinness and concerns associated with weight gain. These findings have implications for our understanding of the role of culture in shaping body image among girls and may prove useful in the development of future survey research that can be implemented among both Fijian and Western adolescents.

The effects of exposure to feminist ideology on women's body image

Body image disturbance has become a common problem among women and there is a need to focus on creating empirically supported treatments. Psychoeducational interventions have reduced body image dissatisfaction, but their impact is limited because they do not offer women adaptive methods of interpreting the many appearance-related messages they receive. This study examined if exposure to a feminist perspective may provide alternative interpretations of cultural messages, thereby increasing body image satisfaction. Participants were randomly assigned to a feminist or psychoeducational intervention, or a control group. Exposure to the feminist condition resulted in increased self-identification as a feminist and greater appearance satisfaction, and changes in feminist identity were related to positive changes in body image. The findings indicate that exposure to feminist theories may serve as an effective intervention strategy.

The relationship of drive for muscularity to sociocultural factors, self-esteem, physical attributes gender role, and social comparison in middle school boys

This study examines the relationship of three sociocultural factors-media influence, peer teasing, and parent teasing/comments and three potential moderator variables-self-esteem, social comparison, and endorsement of male strength and athleticism-to drive for muscularity in middle school boys. There were 287 seventh and eighth grade boys who completed a questionnaire measuring these variables as well as body mass index (BMI) and pubertal status. Results indicated that media influence and male physical attributes endorsement were particularly important correlates of drive for muscularity. These findings have implications for programs designed to prevent body dissatisfaction among adolescent boys.

Beliefs about the determinants of body weight predict dieting and exercise behavior

This study examined the relation between beliefs about the determinants of body weight and self-reported weight-control behaviors. Restrained eaters and unrestrained eaters indicated their beliefs about amount of food eaten and amount of exercise as determinants of body weight. They also reported the extent to which they engaged in several dieting behaviors and exercise. For restrained eaters (but not for unrestrained eaters), there was a positive correlation between beliefs about amount of food eaten as a determinant of body weight and self-reported dieting behaviors. For both restrained and unrestrained eaters, there was a positive correlation between beliefs about exercise as a determinant of body weight and amount of weekly exercise. These results suggest that (a) specific beliefs about the determinants of body weight can be useful predictors of weight-related behaviors, and (b) restrained eaters are likely to engage in a broader range of behaviors aimed at controlling their weight.

Media literacy as a prevention intervention for college women at low- or high-risk for eating disorders

This study examined whether the media literacy program, ARMED, is an effective prevention intervention for college women at low- or high-risk for an eating disorder. Changes in eating disorder risk factors were assessed in low- (n=26) and high-risk (n=19) women participating in a two-session media literacy intervention as compared to low- (n=31) and high-risk (n=16) controls. Women at high-risk for an eating disorder reported significant decreases in body dissatisfaction, drive for thinness, feelings of ineffectiveness, and internalization of societal standards of beauty after participating in ARMED, whereas control participants did not. No significant decreases in perfectionism, physical appearance comparisons, or awareness of societal standards of beauty were reported among high-risk participants. Changes in eating disorder risk factors were not found among low-risk participants, regardless of treatment condition. Findings suggest that media literacy may be an effective secondary prevention intervention for eating disorders.

Thin-ideal internalization, body dissatisfaction and symptoms of eating disorders in Croatian adolescent girls

The aim of this investigation was to study the relationship between unhealthy eating habits and behaviors, perception and acceptance of societal standards regarding thinness, body dissatisfaction, and family and peer pressure to be thin. One hundred and twentythree high school girls from Rijeka (Croatia) were surveyed using Eating Attitudes Test (EAT- 26), Sociocultural Attitudes Towards Appearance Questionnaire (SATAQ), Body Esteem Questionnaire for Adolescents and Adults (BES), and Scale of perceived pressure to be thin from family and peers. The results of path analyses showed that social pressure from family and peers, experience of weight-related teasing and criticism by family members, contributed to development of eating disturbance. The acceptance of social standards related to appearance, contributed to onset of disturbed eating habits. Weight satisfaction alone influences the development of some eating disorder symptoms, but it is also a mediator of higher body mass index (BMI) and internalization of societal appearance standards. Girls with higher BMI, who accepted societal standards of thin-ideal, perceived major social pressure to be thin through direct and persuasive comments designed to establish the importance of dieting, and probably develop eating disturbed habits, or some symptoms of anorexia (AN) or bulimia nervosa (BN).

Predicting eating disorder group membership: an examination and extension of the sociocultural model

The purpose of this research was to examine and extend portions of the sociocultural model of bulimia nervosa (Stice, E. (1994). Review of the evidence for a sociocultural model of bulimia nervosa and an exploration of the mechanisms of action. Clinical Psychology Review, 14, 633-661; Stice, E., & Agras, W. S. (1998). Predicting onset and cessation of bulimic behaviors during adolescence: A longitudinal grouping analysis. Behavior Therapy, 29, 257-276). Participants were women who reported engaging in binge eating at baseline and the 1-year follow-up (n = 26), women who began binge eating between these 2 points (n = 25), and women who did not report binge eating during the course of the study (n = 199). Results of the first discriminant function analysis provided support for the sociocultural model. However, the results of subsequent analyses suggest that additional variables, including stress, escape-avoidance coping, and interoceptive awareness, emerged as important. Implications of these findings for our understanding of the development and maintenance of binge eating are discussed.

Relational-Interdependent self-construal as a function of bulimic symptomatology

The present study compares differences in the levels of relational-interdependent self-construal among asymptomatic, symptomatic, and bulimic participants in a natural groups' design. Asymptomatic (n = 169), symptomatic (n = 73), and bulimic (n = 21) participants completed the Questionnaire for Eating Disorder Diagnoses (Q-EDD). Contrast tests were conducted to examine group differences in relational-interdependent self-construal as a function of bulimic symptomatology. Findings indicate significantly lower levels of relational-interdependent self-construal among bulimic participants. Results imply disruptions in the interpersonal relationships of bulimic individuals are reflected at the level of the relational self. The present study compares differences in the levels of relational-interdependent self-construal among asymptomatic, symptomatic, and bulimic participants in a natural groups' design. Asymptomatic (n = 169), symptomatic (n = 73), and bulimic (n = 21) participants completed the Questionnaire for Eating Disorder Diagnoses (Q-EDD) and the Relational-Interdependent Self-Construal Scale (RISC). Contrast tests were conducted to examine group differences in relational-interdependent self-construal as a function of bulimic symptomatology. Findings indicate significantly lower levels of relational-interdependent self-construal among bulimic participants. Results imply disruptions in the interpersonal relationships of bulimic individuals are reflected at the level of the relational self.

Prospective predictors of body dissatisfaction in adolescent girls and boys: A five-year longitudinal study

This study investigated prospective risk factors for increases in body dissatisfaction in adolescent girls and boys in the Eating Among Teens Project. At the time of first assessment (Time 1), participants were a cohort of early adolescent girls (N=440) and boys (N=366) and a cohort of middle adolescent girls (N=946) and boys (N=764). Participants were followed up 5 years later (Time 2). Potential prospective risk factors examined included body mass index, socioeconomic status, ethnicity, parent dieting environment, peer environment, and psychological factors. Predictors of Time 2 body dissatisfaction were Time 1 body dissatisfaction, body mass index, socioeconomic status, being African American, friend dieting and teasing, self-esteem, and depression. However, the profile of predictors differed across the samples.

Implicit and explicit attitudes toward fatness and thinness: The role of the internalization of societal standards

Two studies examined restrained and unrestrained eaters' implicit and explicit attitudes toward fatness and thinness. Participants completed measures of implicit and explicit attitudes toward fatness and thinness (Studies 1 and 2), and a measure of the internalization of sociocultural attitudes toward thinness (Study 2). Restrained and unrestrained eaters both had strong implicit negative attitudes toward fatness, but restrained eaters had stronger negative explicit attitudes and beliefs about fatness. Explicit attitudes and beliefs were related to the degree of internalization of sociocultural attitudes, and the internalization of sociocultural attitudes partially mediated the relation between dietary restraint and explicit attitudes. These results suggest that most people are aware of societal standards regarding fatness and thinness and have developed negative implicit attitudes toward fatness, but that only some people (in particular, restrained eaters) have internalized these standards and developed negative explicit attitudes toward fatness that they endorse as personal beliefs.

The Stice model of overeating: Tests in clinical and non-clinical samples

The present study tested the dual pathway model of Stice [. A review of the evidence for a sociocultural model of bulimia nervosa and an exploration of the mechanisms of action. Clinical Psychology Review, 14, 633-661 and . A prospective test of the dual-pathway model of bulimic pathology: mediating effects of dieting and negative affect. Journal of Abnormal Psychology, 110, 124-135.] in a non-clinical sample of female adolescents and a clinical sample of female eating disorder patients. The model assumes that negative affect and restrained eating mediates the link between body dissatisfaction and overeating. We also tested an extended version of the model postulating that negative affect and overeating are not directly related, but indirectly through lack of interoceptive awareness and emotional eating. Structural equation modelling was used to test our models. First, in the two samples, body dissatisfaction and drive for thinness were associated with overeating/binge eating. In both clinical and adolescent sample, we found support for the negative affect pathway and not for the restraint pathway. Lack of interoceptive awareness and emotional eating appear to (partly) explain the association between negative affect and overeating. Emotional eating was much more strongly associated with overeating in the clinical than in the adolescent sample. In sum, we found substantial evidence for the negative affect pathway in the dual pathway model. The link between body dissatisfaction and overeating in this respect might be explained by the fact that negative affect, due to body dissatisfaction, is related to a lack of awareness of personal feelings and to eating when dealing with negative emotions, which on its turn is associated with overeating.

How do adolescent girls evaluate body dissatisfaction prevention messages?

PURPOSE

This research examined responses of adolescent girls to messages typically used in eating disorder and body image prevention programs and 2 new messages promoting a positive body image and persuading against body comparison with the media and peers.

METHODS

Girls in the 7th, 8th, and 10th grades completed a questionnaire assessing comparison tendency, internalization of the thin body ideal, body image concerns, psychological functioning, and risk factors for eating disorders. Two weeks later, participants viewed on videotape 9 persuasive messages and 1 nonpersuasive control message and rated them on relevance, believability, emotional response to body, intention to compare, and intention to diet.

RESULTS

Two message themes frequently used in prevention programs (1. media images are not real, and 2. the ideal body changes through history and between cultures) and 1 new message (don't fall into the comparison trap) were rated most strongly. Relevance ratings consistently were associated positively with body comparison, internalization of the thin ideal, body dissatisfaction, and dieting measures.

CONCLUSIONS

Body dissatisfaction prevention messages vary in their persuasiveness and this research identifies messages that potentially are of particular value for inclusion in intervention programs.

Ethnicity as a protective factor against internalization of a thin ideal and body dissatisfaction

OBJECTIVE

We examined the potential for ethnicity to moderate the relationships between awareness and internalization of sociocultural ideals of appearance and between internalization and body dissatisfaction.

METHOD

Spanish (n = 100), Mexican American (n = 100), and European American (n = 100) female participants completed measures of sociocultural attitudes and body dissatisfaction. Path analysis using maximum likelihood with robust standard errors tested the relationships across and within ethnic groups.

RESULTS

There was evidence for the mediational effect of internalization on the relationship between awareness and body dissatisfaction. Furthermore, both relationships were significantly stronger for European American women than for Mexican American or Spanish women (the predicted moderator effect).

DISCUSSION

Results demonstrate how ethnicity may protect against the development of eating disorder symptoms and suggest that eating disorder prevention should involve denouncing the thin ideal, minimizing appearance as an indicator of value, and emphasizing traits other than appearance as determinants of worth.

Anthropomorphic characteristics of centerfold models: trends towards slender figures over time

OBJECTIVE

Anthropomorphic characteristics of centerfold models were analyzed to determine if there has been a trend towards slimmer models over the last 50 years.

METHOD

Height and weight, breast, waist, and hip measurements of 559 Playboy centerfold models, obtained from the magazine's website, were analyzed.

RESULTS

Regression analyses indicated a gradual and subtle change towards slimness. A latent class analysis yielded five basic types of figures and results indicated that the prevalence of the type of figures being depicted changed over time, with a slightly thinner figure being more common. However, really thin figures were rare until the 2000s and the probability of a model having a body mass index (BMI) < 17 was greater in the 1950s than in the 2000s.

DISCUSSION

These findings suggest that there has been a trend towards slimness, but that the changes have been gradual.

The Use of Photo-interviewing: Three Examples from Health Evaluation and Research

This article reviews the use of photographs as data within the social sciences as well as defining related terminology used over the past century. It then examines the use of photos as stimuli for talking about health settings before presenting three recent case studies where photo-interviewing has been used successfully in health evaluation and research. Advantages and limitations of the method are considered.

The role of social norms and friends’ influences on unhealthy weight-control behaviors among adolescent girls

Dieting is common among adolescent girls and may place them at risk of using unhealthy weight-control behaviors (UWCBs), such as self-induced vomiting, laxatives, diet pills, or fasting. Research has suggested that social factors, including friends and broader cultural norms, may be associated with UWCBs. The present study examines the relationship between the school-wide prevalence of current weight loss efforts among adolescent girls, friends' dieting behavior, and UWCBs, and investigates differences in these associations across weight categories. Survey data were collected in 31 middle and high schools in ethnically and socio-economically diverse communities in Minnesota, USA. The response rate was 81.5%. Rates of UWCBs were compared across the spectrum of prevalence of trying to lose weight and friends' involvement with dieting, using chi(2) analysis and multivariate logistic regression, controlling for demographic factors and clustering by school. Girls with higher body mass index (BMI) were more likely to engage in UWCBs than those of lower BMI. Multivariate models indicated that friends' dieting behavior was significantly associated with UWCBs for average weight girls (OR = 1.57, CI = 1.40-1.77) and moderately overweight girls (OR = 1.47, CI = 1.19-1.82). The school-wide prevalence of trying to lose weight was significantly, albeit modestly, related to UWCBs for average weight girls (15th-85th percentile; OR = 1.17, CI = 1.01-1.36), and marginally associated for modestly overweight girls (85th-95th percentile; OR = 1.21, CI = .97-1.50), even after controlling for friends' dieting behaviors. The social influences examined here were not associated with UWCBs among underweight ( < 15th percentile) or overweight ( > 95th percentile) girls. Findings suggest that social norms, particularly from within one's peer group, but also at the larger school level may influence UWCBs, particularly for average weight girls. Implications for school-based interventions to reduce UWCBs are discussed.

Influences of ethnicity and socioeconomic status on the body dissatisfaction and eating behaviour of Australian children and adolescents

The present study examined the association between socioeconomic status (SES), ethnicity, body dissatisfaction, and eating behaviours of 10- to 18-year-old children and adolescents. The study participants (N = 768) were categorised as Caucasian (74.7%), Chinese or Vietnamese (18.2%), and Italian or Greek (7.0%), and high (82%), middle (8.6%), and low SES (9.4%) according to parents' occupations. The chi(2), Mann-Whitney U test and Kruskal-Wallis test and logistic regression model were used to determine the interaction between variables. Females and older participants were more likely to desire a body figure that was thinner than their perceived current figure. Furthermore, the same groups were also more likely to be preoccupied with eating problems (females 7.1% vs. males 1.4%; for participants aged 15-18 years, 7.8% vs. participants aged 10-14 years, 3.9%). The body dissatisfaction gender difference was females 42.8% vs. males 11.8%, and participants aged 15-18 years 41.7% vs. those aged 10-14 years, 28.3%. Participants whose parents were managers/professionals were more likely to desire a body figure that was thinner than their perceived current figure than those from white-collar and blue-collar families. This was also the case for Caucasian Australians compared to those from Chinese or Vietnamese backgrounds. In conclusion, age and gender differences in body image and problems in eating behaviour were evident among children and adolescents. However, there was no significant SES and ethnic difference in the proportion of participants with eating problems and body dissatisfaction.

Effects of negative mood induction and impulsivity on self-perceived emotional eating

OBJECTIVE

The current study investigates the influence of negative mood induction and impulsivity on self-perceptions with respect to emotional eating. Negative affect as well as high impulsivity was expected to increase levels of self-perceived emotional eating.

METHOD

College students who were high versus low in impulsivity were assigned randomly to either a negative (failure on a quiz) or a neutral mood induction. Their levels of self-perceived emotional eating were measured after and before mood induction.

RESULTS

Negative affect appeared to enhance the level of self-perceived emotional eating significantly (p < .01). There was no statistically significant effect of impulsivity. The interaction effect of affect and impulsivity approached significance (p = .08), indicating that highly impulsive subjects compared with subjects low in impulsivity were more strongly influenced by negative affect in self-perceived emotional eating.

DISCUSSION

Negative affect substantially influences self-perceptions in terms of emotional eating, which is relevant for both prevention and treatment.

Impact of exposure to idealised male images on adolescent boys' body image

Research examining the impact on adolescent boys of exposure to muscular, athletic, idealised male images has been limited. This research had two aims (i) to investigate the mean effect on state body satisfaction and mood of exposure to idealised male images in adolescent boys, and, (ii) to identify individual attributes that predicted change in state body satisfaction, depression and anxiety following image exposure. One hundred and six boys (mean age=15.6 years) completed a self-report questionnaire on body image attitudes and psychological status. One week later, participants were divided into two groups, one that viewed idealised male images (experimental condition) while the other viewed non-figure advertising images (control condition). Three body satisfaction Visual Analogue Scale (VAS), and a depression and anxiety VAS were completed immediately prior to and following image exposure. In the experimental compared to control condition, there were no significant changes on Want Toned Body, Want to Change Body Shape, Depression and Anxiety VAS following image exposure. However, there was a significant improvement in Like Body Shape VAS. In the experimental group, high internalisation of the muscular, athletic ideal predicted more negative response to viewing images on the body image and Depression VAS. Prior body dissatisfaction significantly predicted negative response to Body Shape Liking and Anxiety VAS. While on average, adolescent boys in this research were not negatively affected by exposure to idealised male images, reaction to exposure is dependent on individual attributes.

Body dissatisfaction in married women: the role of spousal influence and marital communication patterns

Family factors and the media have been established as determinants of body satisfaction, yet little research has looked at the contribution of spousal influence in body dissatisfaction. Marital quality and satisfaction can be a protective factor in the health of women, while high rates of criticism have been associated with poorer health outcomes. The present study investigated the relationship between perceptions of family and spousal factors and body dissatisfaction in married women. Additionally, the impact of marital communication was investigated. Seventy-seven married women completed self-report questionnaires assessing familial body-focused comments, spousal evaluation of a wife's body, marital communication patterns, and body dissatisfaction. After controlling for weight status, women's perceptions of familial body-focused comments and spousal evaluation emerged as significant predictors of body dissatisfaction. It was also found that more destructive communication patterns moderated the effect of perceived spousal evaluation on body dissatisfaction. This study provides some context for understanding the impact of specific influences on women's body dissatisfaction.

Body image importance and body dissatisfaction among indigenous Australian adolescents

Despite their elevated risk of health problems and a propensity to be more overweight or underweight relative to the other members of the Australian population, there has been no previous investigation of body image concerns among Indigenous Australians. In this study we investigated the level of body image importance and body image dissatisfaction among 19 rural Indigenous adolescents (7 males, 12 females) and 28 urban Indigenous adolescents (15 males and 13 females). Our hypotheses that there would be gender differences in body image importance and body image satisfaction were not generally supported. However, males placed more importance on muscle size and strength than females, and rural participants placed more importance on weight than urban participants. Comparison to existing data obtained from Caucasian adolescents suggested that Indigenous youth may be less concerned and dissatisfied with body weight and shape. These results are discussed in relation to findings from studies of non-Indigenous adolescents, and Indigenous health issues. The limitations of the current study and the need for further studies are also discussed.

Subtyping female adolescent psychiatric inpatients with features of eating disorders along dietary restraint and negative affect dimensions

Cluster-analytic studies of eating disorders in adult patients have yielded two subtypes (pure dietary and mixed dietary-negative affect). This study aimed to replicate the subtyping in female adolescent psychiatric inpatients with features of eating disorders. Cluster analyses of 137 patients with eating-disordered features revealed a dietary-negative affect subtype (43%) and a pure dietary subtype (57%). The dietary-negative affect subtype was characterized by greater likelihood of binge eating, greater eating-related psychopathology, and greater body image dissatisfaction. The two subtypes did not differ significantly in scores reflective of clinical syndromes (other than the significantly higher depressive affect in the negative affect subtype), but the dietary-negative affect subtype was characterized by greater personality disturbance and higher reported concerns in clinical areas, including suicidality and childhood abuse. The cluster analysis produced different results from an alternative approach to subtyping by vomiting. These findings provide further support for the reliability and validity of this subtyping scheme for eating pathology. Clinically, the findings suggest that the combination of dieting and negative affect signals a more disturbed variant of eating-disorder related psychopathology in female adolescent psychiatric inpatients.

The development of eating pathology in Chinese-Australian women: acculturation versus culture clash

OBJECTIVE

Recent research suggests there has been an increase in the incidence of eating pathology among Asian women residing in the West. Two alternate explanations for the development of this eating pathology have been proposed; acculturation versus culture clash. The current study was designed to further examine the influence of acculturation versus culture clash on the development of eating pathology in Chinese-Australian women.

METHOD

Eighty-one Chinese-Australian women completed a questionnaire investigating their level of eating pathology, perceived sociocultural influences to lose weight, parental overprotection and care, self-perceptions of physical appearance, sociability and global self-worth, and the strength of their ethnic identity.

RESULTS

It was found that, overall, low levels of satisfaction with physical appearance, high levels of parental overprotection, and high levels of perceived pressure from best female friends to lose weight predicted greater eating pathology in both acculturated and traditional women. However, acculturated women who perceived higher levels of pressure from their fathers and best male friends to lose weight and traditional women who experienced higher levels of parental care reported the greatest eating pathology.

DISCUSSION

The findings suggest that there are both similarities and differences between the risk factors that correlate with eating pathology between acculturated and traditional women.

Psychometric evaluation of the Body Change Inventory: an assessment instrument for adolescent boys and girls

A new instrument, the Body Change Inventory, was developed to provide an assessment of body change strategies that are used by both adolescent girls and boys. The novel aspect of this instrument is that it evaluates strategies to increase body size and increase muscle size, as well strategies to decrease body size. Independent samples of adolescent girls and boys aged between 11 and 17 years (N=1732) participated in four studies. The revised instrument consisted of three body change scales-Strategies to Decrease Body Size, Strategies to Increase Body Size, and Strategies to Increase Muscle Size. The studies demonstrated content validity, construct validity, internal consistency, and concurrent and discriminant validity for the new scales. The new scales provide a valuable addition in the literature for assessing three global body change strategies among adolescent girls and boys. They are needed in order to examine further the normative development of different kinds of body change strategies and how these may lead to behavioural problems such as disordered eating, exercise dependence, and steroid use.

A Biopsychosocial Model of Disordered Eating and the Pursuit of Muscularity in Adolescent Boys

This review provides an evaluation of the correlates and/or risk factors associated with disordered eating and the pursuit of muscularity among adolescent boys. One of the main conclusions is that similar factors and processes are associated with both behavioral problems. Several factors found to be consistently associated with disordered eating among boys are also similar to those found with girls. These include body mass index, negative affect, self-esteem, perfectionism, drug use, perceived pressure to lose weight from parents and peers, and participation in sports that focus on leanness. However, as many of the findings have only been verified using cross-sectional designs, prospective studies are now needed.

Body Image and Eating Disturbances Across Ethnic Groups: More Similarities Than Differences

Sociocultural models of eating pathology posit that ethnic minority groups should show fewer eating disturbances than Whites. Thus, the authors tested whether there were ethnic differences in eating disorder symptoms and risk factors for eating pathology and whether the relations between risk factors and eating pathology differed across ethnic groups, with data from adolescent and adult females (N = 785). Only 1 of the 14 tests of main effect differences between ethnic groups was significant and none of the 49 tests of whether ethnicity moderated the relations of risk factors to eating pathology were significant. Findings provide little support for the hypothesized ethnic differences in eating disturbances and suggest that ethnic minority groups have reached parity with Whites in this domain.

Thin ideals in music television: a source of social comparison and body dissatisfaction

OBJECTIVE

The study investigated the impact of thin idealized images of women as presented in music television, a popular form of entertainment for young people.

METHODS

A sample of 84 women viewed a videotape containing either appearance music videos (which emphasized appearance and featured thin and attractive women) or non-appearance music videos. The instructional set was also manipulated to encourage or discourage social comparison.

RESULTS

Viewing the appearance music videos featuring thin women led to increased social comparison and body dissatisfaction. Regression analyses showed that the effect of video condition on body dissatisfaction was mediated by the level of comparison processing.

DISCUSSION

The study demonstrated that the content of television programming can have negative consequences for women's body image. In addition, it offered social comparison processing as both a theoretic mechanism and a practical target for intervention.
