Anorexia nervosa and bulimia nervosa have emerged as the predominant eating disorders. We review the recent research evidence pertaining to the development of these disorders, including sociocultural factors (e.g., media and peer influences), family factors (e.g., enmeshment and criticism), negative affect, low self-esteem, and body dissatisfaction. Also reviewed are cognitive and biological aspects of eating disorders. Some contributory factors appear to be necessary for the appearance of eating disorders, but none is sufficient. Eating disorders may represent a way of coping with problems of identity and personal control.

    • "Second, it has been reported that people with eating pathology deny having a problem and often only become engaged in treatment at an advanced stage of the illness (Polivy & Herman, 2002). Individuals were recruited from both the university and the community to ensure sufficient variance in the data to test the psychometric properties of the developed scale. "

    ABSTRACT: Key practitioner message: The PEP-S is a valid, reliable, quick and easy to administer self-report questionnaire that measures pride related to eating pathology. The PEP-S assesses four clinically relevant dimensions: (1) pride in weight loss, food control and thinness, (2) pride in healthy weight and healthy eating, (3) pride in outperforming others and social recognition and (4) pride in capturing other people's attention due to extreme thinness. The PEP-S has very good internal and test-retest reliability, and very good convergent and discriminant validity. The PEP-S distinguishes between women with higher and lower levels of eating psychopathology. The PEP-S makes an important contribution to understanding pride in eating psychopathology, which is essential from both clinical and theoretical perspectives.

    • "A long tradition of work within eating disorders has emphasized that parenting plays some role in the emergence and maintenance of eating pathology (Polivy & Herman, 2002). Moreover, research based in theories such as the social expectation model of perfectionism (Flett, Hewitt, Oliver, & Macdonald, 2002) has emphasized that parental characteristics have an influence on how perfectionism develops (Flett et al., 2002).

    ABSTRACT: Perfectionism mediates the relation between parental psychological control and disordered eating, but it is unclear whether it functions similarly within associations between other parenting characteristics and eating pathology. The current study tested socially-prescribed perfectionism (SPP) as a mediator of the relations between two facets of perceived parenting style—autonomy support and psychological control— with disordered eating. Undergraduates (N = 333, 100% female) completed self-report measurement of study variables. Results indicated that psychological control and autonomy support were moderately correlated. Additionally, the indirect effect of parenting variables on disordered eating through SPP was significant across reports for both mother and father. When the directionality of variables was reversed, no indirect effects were significant, supporting the hypothesized relations between study variables. Findings reinforce prior work highlighting perfectionism as an important mechanism in the etiology of disordered eating.

    • "In addition, this struggle to identify, coupled with the pressures of heteronormative identity development, may also help explain why the unsure females in our sample were most at risk for DES. In fact, in a meta-analysis exploring the risk factors of EDs, Polivy and Herman (2002) highlight problems of identity and personal control as some of the primary individual risk factors that contribute to the development of EDs. Unsure females may try to resolve their feelings of uncertainty by controlling their food intake and/or " the pursuit of slimness " (p. "

    ABSTRACT: Research shows that gay and bisexual males are at increased risk for disordered eating symptoms (DES); however, studies examining DES amongst lesbians and bisexual women have produced mixed findings. Furthermore, few studies have included questioning or "unsure" individuals. This study examined DES symptoms in adolescents and young adults across self-reported sexual attraction and behavior. Participants were recruited from ten primary care sites in Pennsylvania and administered the Behavioral Health Screen (BHS) - a web-based screening tool that assesses psychiatric symptoms and risk behaviors - during a routine visit. As expected, males who were attracted to other males exhibited significantly higher disordered eating scores than those only attracted to members of the opposite sex. Males who engaged in sexual activities with other males also exhibited significantly higher scores than those who only engaged in sexual activities with females. Amongst females, there were no significant differences in DES scores between females who were only attracted to females and those only attracted to males. Those who reported being attracted to both sexes, however, had significantly higher scores, on average, than those only attracted to one sex. More surprisingly, females who were unsure of who they were attracted to reported the highest DES scores of all. These findings are contrary to previous assumptions that same-sex attraction plays a protective role against eating pathology in females. Females who are unsure or attracted to both sexes may actually be at increased risk for developing DES. Copyright © 2015 Elsevier Ltd. All rights reserved.
