The aim of the present study was to examine the level of body image disturbance among adolescent boys and to determine how body image disturbance was related to body change techniques. Twenty boys from year 7 (mean age = 12.55 years, SD = 0.61) and 20 boys from year 9 (mean age = 14.85 years, SD = 0.59) were interviewed individually about their body image and body change strategies. The boys were questioned about the importance and their satisfaction with their weight, body size, body shape, muscle tone and parts of their body and the frequency with which they used the following techniques: eating less to lose weight, eating more to gain weight, and exercise to change body size, shape or muscle tone. The results demonstrated that of those boys who wanted to change their body (50 per cent), 12 wanted to lose weight and eight wanted to gain weight. The most frequent strategy used to change body size or shape was exercise, rather than changing eating patterns. Year 7 boys were more satisfied with their weight than year 9 boys, and boys with a larger body mass index (BMI) were less satisfied with their muscle tone and more likely to change their eating habits to decrease their body size or shape than boys with a smaller BMI. The implications of these findings for obtaining a better understanding of how male body image and body change strategies are different from girls are discussed.

The present study was concerned with the impact of pubertal development, relationships with peers and perceived pressure from the media on body dissatisfaction and body change behaviors among adolescent boys and girls. In particular, the study investigated the underresearched area of strategies to increase weight and muscle. The exploration of body change strategies among adolescent boys has been a neglected area of research. Methods: Respondents were 1185 adolescents (527 males, 598 females) who were enrolled in Grades 7 and 9. Participants completed measures of pubertal development, media and peer influence, body dissatisfaction and strategies to lose weight, increase weight and to increase muscle. Results: The findings demonstrated that girls were more likely than boys to adopt strategies to lose weight, whereas boys were more likely to adopt strategies to increase muscle tone (but not weight). For boys in both Years 7 and 9, the main predictors of body change strategies were puberty and, to a lesser extent, perceived popularity with peers. The major influences for Years 7 and 9 girls were puberty and the media, but these mainly focused on weight loss. For Year 9 girls, perceived popularity with opposite-sex peers also predicted body dissatisfaction and strategies to increase muscle tone. Conclusion: The implications of these findings for understanding factors related to a range of body change strategies for adolescent boys and girls are discussed.

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.

The present study examined the utilization of social comparison practices and the role of negative affect in predicting body dissatisfaction, problem eating, and muscle preoccupation among young children. Participants were 236 children aged between 8 and 10 years. Children's eating, exercising, and muscle concerns were examined using a modified version of the Children's Eating Attitudes Test (ChEAT), which included additional items pertaining to muscle bulk and exercising. Consistent with past findings, body mass index (BMI) was found to be the sole unique indicator of body dissatisfaction for both boys and girls. Utilization of social comparison practices with adults was the main unique indicator of the modified ChEAT factors for boys, while BMI was the main unique indicator of the modified ChEAT factors for girls. In addition, negative affect was associated with binging, food preoccupation, and social pressure to eat for boys and dieting and muscle preoccupation for girls. Findings are discussed in relation to previous studies with adolescents and adults.

In this research, content analysis was employed to investigate older adults' perceptions of successful aging and the relationship of these perceptions to definitions given in the literature to date. Participants were 18 males and 42 females between the ages of 70 and 101 years. Analyses revealed older adults mentioned only 1 or 2 criteria of successful aging if asked for a definition; however, when prompted, they rated almost all the criteria emerging from the literature as highly important. Participants reported adjusting to the situations they were in by compensating for losses that occurred and selecting activities that best suited their capabilities. Overall, older adults' perceptions of successful aging were similar to aspects identified in the literature. Not all aspects, however, were seen as important by all participants, and only low to moderate correlations were found between some aspects of successful aging. (Contains 3 figures and 4 tables.)

Two alternate processes that may explain the relationship between child maltreatment, childhood family characteristics and adult adjustment (mediation and moderation) were tested using retrospective data from a community sample (N = 175). The levels of five different types of child maltreatment did not mediate the relationship between childhood family variables and adult adjustment. In contrast, family background played a mediating role in the relationship between maltreatment and adjustment. Evidence of moderation was found in the interactions between different maltreatment types in predicting adjustment. Partial support was found for the moderating influence of family factors on the relationship of maltreatment to adjustment.

In this study we examined the role of biopsychosocial factors on adolescent boys' body modification strategies over an 8-month period. Participants were 434 adolescent boys aged between 11 and 16 years. The majority of respondents were from Anglo-Australian backgrounds (83%); the others were from Asian and European non-English-speaking backgrounds. The results indicated a consistent relationship between perceived encouragement to engage in body change strategies and increases in adolescents' body modification strategies, including muscle gain, weight gain, and weight loss. In addition, poor parent relations, being younger, and higher scores on the pubertal development scale predicted increased use of food supplements. However, the stability of the body modification strategies and the examined variables over the 8-month period were low. Further studies are needed to examine the stability of adolescent self-perceptions over both longer and shorter periods. Moreover, researchers need to include other factors that may be more relevant for adolescent boys (e.g., involvement in sports).

The study examined the role of body dissatisfaction, body image importance, sociocultural influences (media and parent and peer encouragement), self-esteem and negative affect on body change strategies to decrease weight and increase muscles in adolescent boys and girls. Surveys were administered to 587 boys and 598 girls aged between 11 and 15 years. For both genders, parent and peer encouragement and negative affect were the primary predictors of body dissatisfaction, body image importance and strategies to decrease weight and increase muscles. In addition, body image importance was a significant factor in the development of both types of body change strategies, while the media only predicted strategies to decrease weight. Lastly, the effects of self-esteem were mediated by body dissatisfaction. For boys, a stronger focus on body importance occurred among the boys who were generally satisfied with their bodies while the reverse was the case for girls.

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 was designed to examine the factors predicting a range of body change strategies among adolescent males over an 8-month time period. This is the first published longitudinal study of body change strategies to increase weight and muscles among males. The 5 body change strategies in the present study were eating and exercise to lose weight, increase weight, increase muscles, bingeing, and use of food supplements. The extent to which Body Mass Index (BMI) and these body change strategies predicted each other over an 8-month period was evaluated. The role of pressure from parents and peers to lose weight, increase weight, or increase muscles was also evaluated. After controlling for the Time 1 level of each variable, only bingeing, and use of food supplements were predicted by other Time 1 body change variables. Bingeing at Time 1, and a combination of all of the other variables predicted bingeing at Time 2; use of food supplements and bingeing at Time 1 predicted the use of food supplements at Time 2. Perceived pressure from parents and peers to lose weight at Time 1 predicted strategies to lose weight at Time 2; perceived pressure from parents and peers to increase weight at Time 1 predicted strategies to increase weight at Time 2; and perceived pressure to lose weight, increase weight, and increase muscles at Time 1 predicted the use of food supplements at Time 2. These results indicate that extreme body change strategies are predicted by the adoption of more normative body change strategies at an earlier point in time, and that a range of body change strategies among adolescent males are affected by perceived pressures from parents and peers.

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.

This study examined 3 aspects of the male gender role and their relationship to alcohol and cannabis involvement in young adult Australian men (N = 160) aged between 18 and 25 years. Higher scores on the Restrictive Emotionality scale, which assessed gender ,role conflict, were found to relate to both alcohol-related problems and cannabis use. Higher scores on the Antifemininity scale, which assessed traditional attitudes toward men, were also found to be associated with alcohol-related problems. However, lower scores on another aspect of gender role conflict, Restrictive Affectionate Behavior Between Men, and lower scores on one aspect of traditional attitudes toward men, Status Rationality, correlated with higher frequency levels of alcohol and cannabis use.

In this paper, we take a step toward explaining how events occurring within the expatriate assignment are perceived and interpreted. In particular, we consider the conditions under which individuals perceive hassles and uplifts during intercultural interactions as a cognitive or affective event and, how the type of event influences the outcomes associated with a given event. In doing so, we develop a model to propose how characteristics of the perceiver and the event influence whether interactions in the expatriate assignment are perceived as a cognitive or affective event and, how the type of event influences the outcomes associated with a given event.

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.
