Onset of disordered eating attitudes and behaviors in early adolescence: interplay of pubertal status, gender, weight, and age

The interplay of puberty, gender, weight, and age in regard to body image and disordered eating behaviors and attitudes was investigated in a sample of early adolescents. It was found that, after menarche, females had increased personal expectations and were dissatisfied with weight/shape changes. They wanted to reduce their weight and between-meal eating (which was associated with increased feelings of inadequacy, loss of control, and decreased self-esteem). Young postmenarcheal females who were higher achievers and had higher trait anxiety were more likely to have lower weight. Young males at puberty desired to build up their bodies, believing that appearance was important to their sexual appeal. They were also more willing to form close relationships. Postpubertal males felt most in control of their lives, had the highest self-esteem, and were more trusting of their body cues. Overall, high achieving, more anxious postmenarcheal females were at greatest risk for eating disturbances. These results indicate that the interaction of pubertal status and gender must be considered when developing intervention programs.     

Age-independent effects of pubertal status on behavioral constraint in healthy adolescents

Studies have examined age-related changes in personality traits from adolescence through young adulthood, finding that aspects of negative emotionality decrease while conscientiousness increases over time. Varied mechanisms may underlie these transitions, including puberty-driven hormonal changes. Here, healthy adolescents completed the Multidimensional Personality Questionnaire-Brief Form and self-report measures of pubertal status at baseline and after two years. Independent of age, pubertal status impacted primary trait scales of the MPQ-BF Constraint factor in a sex-specific manner. Females decreased in Constraint, and particularly Control, while males increased in Constraint, and particularly Harm Avoidance, with advancing puberty. Longitudinal analyses validated these findings for Control. Findings are discussed relative to males’ versus females’ achievement of optimal levels of behavioral control in adolescence.

Grade, pubertal status, and gender-related variations in conflictual issues among adolescents

The purpose of this study was to describe adolescent perceptions of conflictual family issues, and to ascertain if the intensity of these issues is associated with adolescent grade in school, pubertal status, and gender. The sample was comprised of 279 junior high and senior high school students. Each participant completed a self-report measure of pubertal status, a demographic questionnaire, and the Issues Checklist. Principal factor analysis with varimax rotation of the Issues Checklist resulted in the retention of four factors accounting for 71.59% of the variance. Stepwise regression analyses were conducted for each emergent factor with grade in school, pubertal status, and gender serving as predictors. The results of these analyses indicated that the intensity of School Issues and Household Behavior Issues is greater among seventh and ninth graders than among eleventh graders. Self-Responsibility Issues were perceived as being most intense among transpubertal adolescents. Finally, boys perceived more intense conflict over Persistent Issues and Concerns than did girls.     

Cultural influences on body dissatisfaction,body change behaviours,and disordered eating of Japanese adolescents

We administered a paper‐and‐pencil questionnaire to 133 female and 99 male Japanese high school students 13–18 years old (M = 15.9, SD = 1.57) from the Kansai area to examine cultural influences on their body image and body change behaviours. Our aim was to ascertain the independent and combined influences from traditional Japanese, modern Japanese, and Western values. Cluster analyses identified four ‘acculturative’ groups: ‘anti‐modern’, ‘traditional’, ‘pro‐modern/anti‐traditional’, and ‘pro‐Western/anti‐Japanese’. Pro‐modern and pro‐Western adolescents were most dissatisfied with their bodies, and pro‐Western adolescents were also most likely to attempt weight loss. The results demonstrate the value of assessing cultural interactions in Japan along three dimensions.     

Body-esteem, body mass index, and risk for disordered eating among adolescents in synchronized swimming

The aim of this study was to examine dimensions of body-esteem, Body Mass Index, and their relations with eating disorder symptoms among 42 elite adolescent athletes engaged in competitive synchronized swimming (M = 15.4 yr., SD = 1.2) and to compare them with 40 athletes in sports with no emphasis on leanness (M = 16.5 yr., SD = .93), and 50 nonathlete college female students (M = 16.3 yr., SD = 1.1). They completed the Body-esteem Scale and the Eating Attitudes Test, and the Body Mass Index was computed. Analysis showed synchronized swimmers reported greater negative feelings about their appearance than the two other groups and low perceptions of how others evaluate their physical appearance. Participants did not differ on the EAT-26. Regression analyses showed that Body Mass Index and Body-esteem Appearance accounted for 38% of the variance in log-transformed Dieting scores of synchronized swimmers. Results are discussed in relation to the literature.     

The impact of adolescent girls' life concerns and leisure activities on body dissatisfaction, disordered eating, and self-esteem.

The aim of this study was to situate adolescent girls' body dissatisfaction, disordered eating, and self-esteem in the context of their life concerns and leisure activities. Questionnaires containing measures of life concerns, leisure activities, body dissatisfaction, disordered eating, and self-esteem were administered to 306 girls with a mean age of 16 years. It was found that although academic success and intelligence were rated as the most important life concerns, an emphasis on slimness was most strongly linked to body dissatisfaction, disordered eating, and global self-esteem. An emphasis on popularity with girls also was related to body dissatisfaction, and hours spent watching television were related to lower self-esteem. In contrast, emphasis on sport seemed to serve a protective function. It was concluded that adolescent girls who have a high concern for slimness should be assisted in decreasing this emphasis in order to improve their general well-being.     

The impact of L1 structural frequency and cognate status on the timing of L2 production

The present study investigates the impact of first language (L1) structural frequency and L1 lexical accessibility, manipulated via cognate status, on second language (L2) speech production. L1 German–L2 English speakers and L1 English speakers completed a production task containing pre- and post-modified possessive noun phrase (NP) constructions (e.g. The actress’s sofa vs. The sofa of the actress) in which the head nouns were English-German cognates (e.g. sofa) or noncognates. While English prefers pre-modified NPs, German has a strong frequency bias for post-modified NPs. L2 English speakers exhibited higher production accuracy than L1 English speakers on post-modified NP sentences. However, facilitative L1 effects in production latencies were restricted to post-modified NP sentences containing cognates and only developed cumulatively after repeated exposure to post-modified NP sentences. We discuss how cognate status and L1 structural frequency differentially influence the accuracy and timing of choosing between different structural alternatives during L2 production.     

Family influence on disordered eating: The role of body image dissatisfaction

Research has linked an appearance-focused family culture (including parental commentary about weight/size) with increased disordered eating and body image dissatisfaction in daughters. Since body image dissatisfaction is also a risk factor for disordered eating, body image dissatisfaction may contribute to the link between family focus on appearance and disordered eating. This correlational study included a sample of 268 college women who completed the Family Influence Scale, Bulimia Test – Revised, Body Shape Questionnaire, and a series of items about their parents’ comments about their weight/size. Both family appearance focus and daughters’ body image dissatisfaction predicted increased disordered eating in daughters. Additionally, body image dissatisfaction partially mediated the influence of family appearance focus on daughters’ disordered eating. No specific type of parental comments regarding weight/size emerged as a superior predictor of eating disturbance, but encouragement to control weight/size was a stronger predictor of body dissatisfaction than other types of parental comments.     

Achievement goal theory and disordered eating: Relationships of disordered eating with goal orientations and motivational climate in female gymnasts and dancers

ObjectivesTo examine the relationships between disordered eating in female gymnasts and dancers and their perspective towards achievement in sport and dance, respectively. With an emphasis on outperforming others (ego involvement), more disordered eating was expected than when personal progress (task involvement) was emphasized.MethodsNinety-four aesthetic performers from gymnastics (n = 59) and dance (n = 35) completed questionnaires measuring ego and task involvement (individual orientation and motivational climate), dieting, self-esteem, perfectionism and weight-related peer and coach pressure.ResultsPartial correlations indicated that a stronger ego orientation was related to more dieting, greater perfectionism, more weight-related peer pressure, and lower self-esteem. Similar relationships were found for performance climate. Mastery climate on the other hand was negatively related to dieting, and coach and peer pressure, suggesting that when performers perceived the motivational climate as mastery, less frequent dieting was reported and less weight-related coach and peer pressure was perceived. No relationships were found between task orientation and disordered eating. Most importantly, regression analysis showed that after controlling for BMI, both ego orientation and mastery climate made a unique significant contribution to explaining dieting variance.ConclusionsGoal achievement theory is an important framework for explaining disordered eating in female aesthetic performers. Both ego orientation and mastery climate play a role in dieting of gymnasts and dancers. Aesthetic performers who are strongly ego-oriented tend to display more disordered eating correlates. Furthermore, it seems that to protect against disordered eating, coaches and teachers should create a mastery climate and target self-improvement and self-referenced comparisons over interpersonal competitiveness.     

The influence of trait anger,trait anxiety and negative urgency on disordered eating

Negative affectivity and impulsivity are potential risk factors for eating pathology. Both are heterogeneous constructs, yielding varied effect sizes in the prediction of pathology. The use of a specific construct, negative urgency, the tendency to act impulsively while distressed, improves the predictive utility of ‘impulsivity’ in eating pathology. The use of specifically defined affectivity constructs may similarly improve theories of risk. Anger and anxiety both represent high arousal, negatively valenced emotions, but promote different interactions with the environment; approach vs. avoidance. Undergraduate women completed measures of negative urgency, trait anger, trait anxiety, and eating pathology 3 months apart. Negative urgency and trait anxiety prospectively accounted for unique variance in increases in global eating pathology, while negative urgency prospectively accounted for unique variance in binge eating. Anger was not a significant predictor. Results suggest that the use of both specifically defined impulsivity and affectivity constructs improves predictive utility of traits in eating pathology.     

The impact of object working memory on timing

Nontemporal information processing involving short-term memory requirements disturbs time estimation. Previous studies mostly used letters or digits, which are maintained in working memory by phonological loops. Since verbal and nonverbal information are processed by separate working-memory subsystems, how do nonverbal, object-based memory tasks affect time estimation? We manipulated visual object memory load using the magic cube materials. Participants were divided into three groups, who completed a reaction-time task (control task), a memory-recognition task interposed by an attempt to produce a 2500-ms time interval (active processing), and a memory-recognition task following time interval production (passive retention). The produced time increased with increasing memory-object size under both the active processing and passive retention conditions; mean produced time interval did not significantly differ between the two experimental conditions. By comparing the reaction times and error rates of a relevant task, we excluded any speed–accuracy tradeoff during timing. This result suggests that when the working-memory information to be processed includes objects requiring attention for retention, the production of time intervals is also affected by memory item maintenance.     

Competing on all fronts: Achievement orientation and disordered eating

Strikingly high prevalence rates of symptoms of disordered eating among college women have been documented. The question arises as to whether one aspect of the college experience, achievement orientation, is associated with disordered eating. Competing hypotheses may be generated regarding the relationship between achievement orientation and disordered eating, with arguments for either a positive or negative relationship. The Work and Family Orientation Questionnaire (WOFO) and the Disordered Eating Symptoms Scale (DESS) were administered to 668 female undergraduate college students. Multivariate analysis of the WOFO subscales revealed that women with high levels of disordered eating obtained significantly higher scores on the Competitiveness subscale than women with low DESS scores. These findings support hypotheses of a positive relationship between competitiveness and disordered eating.     

Defining features of unhealthy exercise associated with disordered eating and eating disorder diagnoses

ObjectivesThe current study sought to compare different features of unhealthy exercise on associations with disordered eating and their ability to identify individuals with eating disorders. A secondary aim of the study was to compare prevalence and overlap of different aspects of unhealthy exercise and potential differences in their gender distribution.DesignCross-sectional epidemiological study.MethodsA community-based sample of men (n = 592) and women (n = 1468) completed surveys of health and eating patterns, including questions regarding exercise habits and eating disorder symptoms.ResultsCompulsive and compensatory features of exercise were the best predictors of disordered eating and eating disorder diagnoses compared to exercise that was excessive in quantity. Further, compulsive and compensatory aspects of unhealthy exercise represented overlapping, yet distinct qualities in both men and women.ConclusionsIncluding the compulsive quality among the defining features of unhealthy exercise may improve identification of eating disorders, particularly in men. Results suggest that the compensatory aspect of unhealthy exercise is not adequately captured by the compulsive aspect of unhealthy exercise. Thus, interventions that target unhealthy exercise behaviors among high-risk individuals, such as athletes, may benefit from addressing both the compulsive and compensatory aspects of unhealthy exercise. Future prospective longitudinal studies will aid in determining the direction of the association between these features of unhealthy exercise and the onset of eating pathology.     

Prevalence and correlates of disordered eating in female figure skaters

ObjectivesThe purposes of this study were to (a) examine the prevalence of disordered eating among female figure skaters, (b) compare levels of disordered eating between skaters and their same-age peers, (c) compare levels of disordered eating between elite skaters and their sub-elite counterparts, and (d) examine general and sport-related correlates of disordered eating (i.e., four sport-related weight pressures, general and sport-related body dissatisfaction, positive and negative perfectionism, self-esteem, and athletic identity).DesignThis study employed a cross-sectional design.MethodsParticipants completed paper–pencil surveys, including measures for disordered eating, four sport-related weight pressures, general and sport-related body dissatisfaction, positive and negative perfectionism, self-esteem, and athletic identity. Participants included 272 female figure skaters ages 12–25 (M = 15.63) across five US states.ResultsThirteen percent of participants scored within range of problematic eating attitudes and behaviors but were no more symptomatic than their same-age peers when compared to existing normative data. Levels of disordered eating did not significantly differ between those competing at the elite and sub-elite level. After controlling for body mass index and age, disordered eating was significantly predicted by self-consciousness of weight and appearance, general and sport-related body dissatisfaction, and positive perfectionism.ConclusionsDisordered eating occurs in female figure skaters across competitive levels. Concern over weight and appearance, dissatisfaction with one's body in general and in sport, and positive perfectionism may serve as important tools in the prevention and detection of disordered eating in female figure skaters.     

The social psychology of disordered eating: The Situated Identity Enactment model

Eating disorders and subclinical behaviours such as dangerous dieting are a significant public health burden in the modern world. We argue that a social-psychological model of disordered eating is needed to explain how sociocultural factors are psychologically represented and subsequently reflected in an individual’s cognitions and behaviour. We present evidence that three central elements shape disordered eating – social norms, social identity and social context – and integrate these within a Situated Identity Enactment (SIE) model. Specifically, the SIE model states that social context determines the salience of both social norms and social identities. Social norms then influence disordered eating behaviour, but only to the extent that they are consistent represented in the content of a person’s social identities. We conclude by outlining the implications of the SIE model for researchers and practitioners in the domain of disordered eating, focusing in particular on the need for, and potential value of, theory-derived social interventions.     

The impact of health education on adolescents

Health education lies on the boundary between family and school. Its contents are therefore difficult to define, even though the need to educate, especially through dialogue, is quite clear. Young people who feel uncomfortable with themselves are already half way to failure.
