Objective Eating disorders have been typically defined as an “adolescent problem.” As a result of emerging evidence which indicated this health problem to be evident in the prepubescent age range, this study aimed to establish prevalence and factors associated with eating/dieting, physical activity, and body image among a nonclinical, naturalistically‐derived sample of preadolescent (aged 10 and 11) school children (n = 61). Method: This cohort of children, which represented the entire grade 6 class of a suburban Elementary school, was measured for body image satisfaction [silhouettes], a participation in activity index, a self‐worth scale and a measure of eating attitudes & behavior [Eating and Me scale [E & M]]. Results: The longitudinal assessment of body image [3 measures over 9 months] indicated signs of stability of “actual” assessments of body image for males, but marked changes for females who preferred to be ideally “chunkier” in stature over time. Physical activity was only implicated with bulimia for the male sub‐group. The E & M scale reported a Cronbach's alpha of .76, with two factors [bulimia; drive for thinness/anorexia] representing 65% of the total variance. Moderate internal validity [r .58] between body dissatisfaction on the E & M scale and the silhouette measure was observed. Discussion: These results demonstrated that body image views and concerns appeared before puberty, that gender differences prevailed with respect to eating/dieting, activity and body image, and that the E & M scale has emerged as a promising research tool. The longitudinal nature of this study of eating disorders also promotes the need for qualitative research methodology and attention to pre‐pubertal cognitive/perceptual processes. © 1997 by John Wiley & Sons, Inc.

Objective This study examined the nature of body image and drive for thinness as multidimensional constructs. Subjects included 111 early adolescent (ages 11–13) girls in Grades 7 and 8 from a private school in Melbourne. Method The participants completed a suite of perceptual, affective/attitudinal, and behavioral measures that included assessment of body mass index, self‐concept, body parts, silhouette discrepancy, self‐worth, multidimensional body image, body image dissatisfaction, social physique anxiety, eating attitudes and behaviors, and physical activity. Results The sample reported moderate levels of body image dissatisfaction and a significant association of body image dissatisfaction with drive for thinness. Findings verified the important contribution of the affective/attitudinal components of body image. Discussion A multidimensional scale devised to test the value of a combined index of self‐perceived size, shape, weight, tone, and appearance proved the most effective predictor among the alternative affective/attitudinal scales of body image dissatisfaction. Drive for thinness, as central to this study, was found to be related to, yet distinct from, body image on the basis of behavioral elements such as dieting and activity levels. These findings have ramifications for the design of future research in the body image, drive for thinness, and disordered eating domains. 2000 by John Wiley & Sons, Inc.

The authors investigated a method for assessing body image satisfaction based on computer manipulation of a digitized image of self using a sample of 56 female students aged 17 to 22 years. The total percentage change when re-sizing the actual image to the ideal by the computer adjustment method was significantly correlated with the figural/silhouette discrepancy method. Both of these measures were correlated significantly with body part satisfaction and body mass index but not with social physique anxiety. Although for this sample the 2 methods yielded similar results, the computer adjustment method addresses several limitations of the figural/silhouette method, such as scale coarseness and the accuracy of proportional change between figural/silhouettes. Furthermore, by using the individual's actual image, potential confounds associated with stylized figure drawings that are typically based on Caucasian physical features are removed. Finally, this method also takes into account the importance of various body parts for determining body image satisfaction.
