Body image and self-concept in adolescent girls [R]

Anorexia Nervosa has been recently recognized as one of the most common chronic illnesses that affects the female adolescent population today. Although there has been an abundance of research into eating disorders in a variety of fields, significant limitations within the research still exist. Since very early descriptions of the disorder, self-concept and body image have been identified as core components of the anorexia nervosa. However, research has been somewhat limited in that there have not been any consistent theoretical underpinnings for self-concept and body image within the eating disorders field. Furthermore, researchers have tended to adopt traditional inferential statistics and multivariate methods to assess the role of self-concept and body image. As a result there has been very little consistency in research results. The current paper summarizes the significant findings from a doctoral thesis that attempted to address current limitations in self-concept and body image literature within the field of eating disorders.

Educational and mental health implications of the multidimensional model of the self-concept for adolescent girls : comparison of clinical and non-clinical samples

The importance of a positive self-concept as an educational outcome and a facilitator of other desirable outcomes are well established within the education research field. Although the multidimensional and hierarchical model of the self-concept is widely accepted within the educational psychology, this perspective is not widely used within the mental health research. Hence, the purpose of the present investigation is to compare the psychometric properties of the short version of the Self-Description Questionnaire (SDQII-S) based on responses by a large sample of female adolescent high school students (N= 829) and a clinical sample of adolescent girls who have been diagnosed with anorexia nervosa (N= 75). The well-established psychometric properties of the longer version of the SDQII generalise well to both samples of adolescent girls, and analyses provided good support for the invariance of the factor structure across the two samples. Furthermore, analyses employing new structural equation modelling approaches to comparing the latent mean differences indicated that there were differences (although surprisingly small) between the two groups that were generally consistent with a priori predictions. The important educational and clinical implications of these results are discussed.

Actual/ideal body images of high school girls and how it affects their self-esteem : implications for educational and clinical institutions

Given that adolescence is a critical period for the development of a positive self-concept and body image, it is imperative that educators have an understanding of adolescent students' body image and their dieting practises and behaviours. Negative body image is an issue that is rife within the adolescent student population in Australia and around the world, and is a factor that is commonly associated with and linked to disturbed eating behaviours and chronic eating disorders like Anorexia Nervosa (AN). Despite the intuitive appeal and importance of investigating adolescents' body image in terms of what adolescents would like to look like and what they think that they look like now, very little research has investigated these concepts. Furthermore, very little research has explored whether there is a difference between these two constructs how this may affect adolescents' self-esteem. This study therefore aimed to explore the actual and ideal body images of adolescent high school girls aged between 12 and 18 years in two samples of adolescents, one with eating disorders (n=76, clinical sample) and one without (n=823 high school sample). Additionally, this study investigates these constructs in relation to self-esteem levels. The results of this study have important implications for educators and clinicians within educational and clinical settings.

Effects of a daily school based physical activity intervention program on muscle development in prepubertal girls

This 12-month prospective controlled intervention evaluated the effect of a general school based physical activity program on muscle strength, physical performance and body composition in prepubertal girls. Fifty-three girls aged 7–9 years involved in a school based exercise program [40 min/day of general physical activity per school day (200 min/week)] were compared with 50 age-matched girls who participated in the general Swedish physical education curriculum (mean 60 min/week). Body composition (DXA), isokinetic peak torque (PT) of the knee extensors and flexors at 60 and 180°/s, and vertical jump height (VJH) were assessed at baseline and 12 months. The annual gain in weight was similar between the groups, but there was a greater increase in total body and regional lean mass (P < 0.05) and fat mass (P < 0.01) in the exercise group. Mean gains in knee extensor PT at 60 and 180°/s were 7.0–7.6% greater in the exercise group (P ranging <0.05–<0.001). No significant differences were detected in VJH. In conclusion, increasing school based physical education to at least 3 h/week provides a feasible strategy to enhance the development of muscle strength and lean mass in prepubertal girls.

Looking after well siblings of adolescent girls with anorexia : an important parental role

Background Research has suggested that well siblings of children with chronic and life-threatening illnesses are at risk for negative outcomes and that parents’ responses to the illnesses can influence the adaptation of well siblings. Yet, parents’ efforts to look after well siblings in the context of illness are rarely considered in literature about sibling adaptation. The importance of attending to the needs of well siblings was a major theme to emerge from a qualitative analysis of the experiences of parents of adolescent girls with anorexia nervosa.

Methods In-depth interviews were conducted with 24 parents of adolescent girls with anorexia and analysed using grounded theory method.

Results The data indicated that parents viewed caring for well siblings in the context of anorexia as an important role and responsibility. Parents reported making conscious and active efforts to look after well siblings by: maintaining normality; compensating for changes to routines; protecting siblings; providing emotional support; and managing the consequences.

Conclusions This paper provides a picture of the actions parents take to help well siblings adapt to anorexia in the family. Further research is needed to develop and expand this understanding to families experiencing a wide range of chronic and life-threatening illnesses. The findings underline the importance of clinical attention and further research into the critical parental role of caring for well siblings.

Muscle determinants of bone mass, geometry and strength in prepubertal girls

Purpose: The aim of this study was to compare the relative contribution of peak muscle force (isokinetic peak torque) with surrogate estimates of muscle force, including leg lean tissue mass (LTM) and vertical jump height (VJH), on bone mass, geometry and strength in healthy prepubertal girls (n = 103).

Methods: Total leg and FN BMC and leg LTM were measured by DXA; the hip strength analysis program was used to assess FN diameter, cross-sectional area (CSA) and section modulus (Z). Isokinetic peak torque of the knee extensors and flexors (60°·s-1) were used as direct measures of peak muscle force. VJH was measured as an estimate of neuromuscular function. Total leg length or femoral length was used as a surrogate measure of moment arm length.

Results: All estimates of muscle function, except VJH, were positively associated with leg BMC (r = 0.72 - 0.90) and FN BMC, geometry and strength (r = 0.35-0.65) (all, P < 0.001). Multiple linear regression analyses revealed that leg LTM and isokinetic peak torque were independently and equally predictive of leg BMC and FN BMC, bone geometry and strength, explaining 8 to 28% of the variance in each of the bone traits after accounting for moment arm length. When isokinetic peak torque was corrected for both leg LTM and moment arm length, it remained an independent predictor of BMC, CSA and Z, but only accounted for an additional 2 to 5% of the variance.

Conclusion: These data suggest that DXA-derived leg LTM can be used as a reasonable surrogate for isokinetic peak muscle forces when assessing bone strength in relation to muscular function in healthy pre-pubertal girls.

Dolly girls : tweenies as artefacts of consumption

The apparent sexualization and exploitation of young girls by the consumer media is a much debated topic in the advanced liberal democracies. This paper will develop the argument that the ‘consumer-media culture’ has established itself as one of the most powerful influences in processes of self-formation for young people, and that a tweenie self can be understood as an artefact of consumption. We will identify and analyse the resources that the consumer media provides to tweenies - girls aged between 9 and 14 - as they seek to fashion a sense of self. The paper presents an analysis of the resources presented to this population of young girls/women by an Australian ‘appearance’ magazine, Dolly. We will argue that these identity resources are limited in scope, are dominated by images of young, slim and attractive females, and position the tweenie self as an artefact of consumption.

Digital media and girling at an elite girls' school

In this article, I draw on Judith Butler's notion of performativity to investigate the role of digital technologies in processes of gendered subjectification (or ‘girling’) in elite girls' education. Elite girls' schooling is a site where the potential of digital technologies in mediating student‐led constructions and explorations of ‘femininity’ sits alongside school‐produced digital media in the form of promotional texts, in which young femininity is regulated by discourses of ‘girl power’. Whilst such schools are well equipped with digital resources that might be utilised towards students' interrogation of how ‘femininity’ is understood, thus politicising the girling process, school‐produced digital media inscribe a more prescriptive picture of ‘who’ an elite school‐girl can ‘be’. Lyla Girls' Grammar School (LGGS) is an elite secondary school in Melbourne, Australia. I report on research undertaken at two institutional levels of LGGS: the ‘school’ level in which digital media representations of young women are produced by the school and the ‘classroom’ level, in which media education pedagogy includes interactive web conferencing software. The use of digital technologies in media education appeared to support student‐led construction and interrogation of femininities to some extent. I argue that this kind of student‐led girling is important in the context of more prescriptive school‐level girling practices.

'Go Grrrl!' : constructions of femininity in the textual practices of elite girls' schooling

In this paper I consider the utility of discourses of ‘girl power’ for understanding, and complicating, the way youthful femininities are produced in schooling. The paper is concerned with expanding the possibilities for how queer theoretical resources might be utilized within studies of girls and schooling. Existing studies have drawn upon Judith Butler’s notion of a ‘heterosexual matrix’ for understanding, and attending to, the way normative discourses of heterosexuality underpin the school-based production of youthful femininities. The term ‘heterofemininities’ has been used in order to label these school-produced intersections of sex/gender/sexuality. Drawing on discourses of ‘girl power’ that gather around ‘voice’ and responsibility, I propose that the production of ‘hetero-femininities’ within educational contexts might be further explored, and thus complicated, when the significance of discourses of ‘girl power’ is considered. I analyse young women’s discussions of key ‘girl power’ icons in popular culture, generated through fieldwork in an elite girls’ school in Australia. In this analysis I explore the intersections of gender/sexuality/girl power that are produced in the young women’s textual practices.
