Children's body image was examined in relation to both sociocultural influences and physical self-concepts, which included sporting ability. Findings showed that physical self-concepts more stongly predicted boys' body image, while girls' body image was more strongly predicted by media pressures. Femininity predicted physical self-concepts among both boys and girls.

This study was designed to examine the relationships between different aspects of body image and psychological, social, and sexual functioning throughout adulthood. The respondents were 211 men and 226 women (age range 18–86 years; mean = 42.26). Respondents completed measures of self-rated attractiveness, body satisfaction, body image importance, body image behaviors, appearance comparison, social physique anxiety, self-esteem, depression, anxiety, and social and sexual functioning. Body image was associated with self-esteem for all groups, but was unrelated to other aspects of psychological, social, and sexual functioning. There were some exceptions; a disturbance in body image was related to problematic social and sexual functioning among middle-aged men and to depression and anxiety symptoms in late adulthood among men and women. Middle-aged men who presented with the type of body image disturbance typical of women were more likely to have impaired interpersonal functioning. These results demonstrate that social aspects of body image appear to be important in understanding psychological functioning in later life.

The findings of this thesis highlighted the role of functional aspects of body image (i.e., self-rated health/ fitness) in positively shaping the well-being of young and middle-aged women. A novel finding was the strong association found between women’s body image and how well they believed they managed their life situations.

Researchers have highlighted the significance of a poor body image in the development of dysfunctional eating but have systematically investigated few other outcomes. The authors examined the relationships between different aspects of body image and psychosocial functioning. Participants were 245 boys and 173 girls from Grades 8 and 9 (M age = 13.92 years, SD = 0.69 years). Respondents completed measures of physical attractiveness, body satisfaction, body image importance, body image behaviors, appearance comparison, social physique anxiety, self-esteem, depression, anxiety, and same-sex and opposite-sex relations. Whereas girls tended to report a more negative body image than did boys, the relevance of body image to self-esteem was similar for boys and girls. Concern about others' evaluation of their bodies was especially important in understanding low female self-esteem, whereas for boys, ratings of general attractiveness most strongly predicted self-esteem. The authors found a negative body image to be unrelated to symptoms of negative affect but to be strongly associated with poor opposite-sex peer relationships, especially among boys. A negative body image also affected same-sex relations among girls.

This study investigated the Tripartite Influence Model of body image and eating disturbance in adolescent females. The model was found to be a satisfactory representation of the social, cultural and individual factors proposed to promote body dissatisfaction, dieting and bulimic behaviours in 14 to 18 year old girls. The portfolio presents four case situations in which the specialist knowledge of a clinical psychologist has shown to be beneficial to pediatric patients, their families, and medical staff at a major metropolitan hospital.

Biosocial models of weight loss and increased muscles were empirically tested among adult exercisers. Although women experienced greater body dissatisfaction, both genders engaged in potentially risky strategies to reach their body goals, ranging from the use of food supplements and steroids to bulimic behaviours and excessive exercise.

This thesis examined the relationships between men's body image, different media influences, sexual orientation, and sexual risk taking. In comparison to heterosexuals, gay men were significantly less satisfied with their bodies. Media influences predicted men's body image, and gay men demonstrated greater internalisation of media messages compared to heterosexual men. Based on four case studies the portfolio demonstrates that motivational interviewing might be a useful approach to manage ambivalence and resistance to clients presenting with an anxiety disorder or a parent-child relational issue.

Although dissociative symptoms have been linked with both food- and appearance-related aspects of eating disorders, the psychological mechanisms underlying these relationships remain unclear. The present study evaluated the hypothesis that the disturbances of self-identity attributed to dissociation can manifest as disturbances of body image and, in turn, undermine body-specific self-evaluations relevant to disordered eating (i.e., body comparison, body dissatisfaction, and internalization of the thin ideal). Ninety-three female university students completed self-report measures of dissociation and body-related aspects of disordered eating. In addition, the method of constant stimuli was used to experimentally derive three measures of body image disturbance: (1) accuracy of body size estimations (body image distortion), (2) ability to discriminate between different body sizes (body image sensitivity), and (3) consistency in one’s body size estimations (body image variability). The findings show that dissociation is related to symptoms of disordered eating, and that these relationships may be mediated by body image instability. Collectively, these findings support the notion that the body image attitudes and behaviours that characterize eating disorders may derive from proprioceptive deficits due to dissociation.

The current study used qualitative methodology to investigate the body image concerns of people with physical disabilities. Three males and four females aged between 22 and 50 years, in Melbourne, Australia, participated in the study. Three participants were heterosexual, two were homosexual and two described their sexual identity as predominantly heterosexual but ‘bicurious’. The data were gathered through individual interviews of approximately 2 h duration, where participants responded to a set of predetermined open-ended questions. The study found that bodily impairment had a negative influence on the participants’ psychological experiences, feelings and attitudes toward their own bodies. The impact of feedback from the social environment was highlighted, and there was evidence suggesting that individuals gradually adjust to their different bodies and increasingly accept their disabilities over time.

The present study was designed to assess the role of biopsychosocial factors in understanding body image concerns and cognitions and behaviors related to losing weight or increasing muscles among 507 children (270 girls and 237 boys) aged between 8 and 11 years. Biological, psychological, and sociocultural factors have been found to be relevant in understanding the development of body image concerns and weight loss strategies among children. However, these factors have not been examined together in a single study; thus, the relative influence of each factors and how these factors may interact is not known. In the current study, body mass index (BMI) was found to be a good indicator of girls' and boys' body dissatisfaction, while the main indicator of children's body change strategies was perceived pressure from parents, peers, and the media. Overall, there were more similarities than differences between girls and boys. The age between 8 and 11 years is a significant period to commence studying body image concerns and body change strategies, as it can be used to help us understand the emergence of gender differences in children's weight and muscle concerns.

This study examined factors that influence body image and strategies to either lose weight or increase muscle among children. Participants were 237 boys and 270 girls. Body mass index (BMI), body dissatisfaction, cognitions and behaviors to both lose weight and increase muscles, as well as self-esteem and positive and negative affect, were evaluated. Self-esteem was associated with body satisfaction, positive affect predicted strategies to lose weight and increase muscles, and negative affect predicted body dissatisfaction and cognitions to lose weight and increase muscles. Boys were more likely to focus on changing muscles. Respondents with higher BMIs were more focused on losing weight but not muscle. The discussion focuses on health risk behaviors related to eating and exercise among children.

Objective: Most past research has focused on body dissatisfaction among females. This paper provides a review and evaluation of studies that have examined body dissatisfaction among males. Body dissatisfaction in males has been associated with poor psychological adjustment, eating disorders, steroid use, exercise dependence, as well as other health behaviors. It is therefore important to understand the level of body dissatisfaction, as well as the factors that are related to this construct. Method: The review is divided into three sections: body dissatisfaction among children, adolescents and adults. Within each section, levels of body dissatisfaction are examined, as well as the research that relates to sociocultural influences on body dissatisfaction. Difficulties in drawing valid conclusions from the data due to methodological problems are highlighted. Results: From the current data, it would appear that there are strong similarities in the levels of body dissatisfaction of male and female children, with most children demonstrating high levels of body satisfaction. During adolescence, boys are about equally divided between wanting to lose weight and increasing weight, but there are few studies that have examined a desire for increased muscle size. In adulthood, men evidence a stronger desire to lose weight as they get older. Conclusion: Overall, past studies have primarily focused on questions that are relevant to females, and there is a need to conduct studies that evaluate areas of body dissatisfaction that have greater relevance for males. This will then allow a better understanding of the relationship between body dissatisfaction and psychological and behavioral problems experienced by males at all stages of the lifespan.
