Body Size Estimation

Clinicians who deal with patients with anorexia nervosa are well acquainted with their patients' inability to recognise their emaciation. The patients' insistence that they are normal weight or even overweight, against clear evidence to the contrary, led Bruch (1962) to state that the misperception reaches “delusional proportions”. Studies of body size perception in anorexia nervosa that have used the ‘body part’ method have invariably found that the patients overestimate their body size (Slade & Russell, 1973; Crisp & Kalucy, 1974; Pierloot & Houben, 1978; Garner et al, 1976; Button et al, 1977; Fries, 1977; Casper et al, 1979) but the majority have not found any significant difference in size estimation between patients and controls (Slade, 1985).

Despite much recent interest in the objective measurement of body image in anorexia nervosa, many questions remain regarding basic mechanisms responsible for the findings as well as their meaning in the disorder. It is unclear if “whole body” measures assess the same underlying phenomena as the “body part” method, and it is unclear if body image disturbances are etiologic or a byproduct of anorexia nervosa. The possible association between self-esteem and body satisfaction and the relationship of the latter variable to actual size estimation supports the hypothesis that size perception may be closely tied to satisfaction with non-physical aspects of self. Finally it must be determined if over estimation is a function of a general psychological disturbance or of a deficit of specific interest in this disorder. Despite these questions, the way in which anorexic patients see themselves as well as the cognitive and affective responses to this perception remains an interesting and potentially fruitful area of study with this disorder.

The aim was to explore the body-image perception of a group of 20 hospitalised anorexic patients, aged 18 to 21 years, undergoing a period of treatment. The instrument used was the Askevold nonverbal perception test as modified by Allamani and colleagues in 1978 to assess perception of the dimensions of different parts of the body by exploiting the capacity to project them into space. The four parts were the head, the thoracic area, the abdominal area, and the pelvic area. Analysis of responses indicated that anorexic patients overestimated the abdominal and the pelvic areas much more than the 20 members of the control group (50% vs 30%). The areas of the head and thorax were perceived almost in their real dimensions by the anorexic patients but were underestimated by the control group.

Body Size Estimation

O objetivo desse estudo foi quantificar a estimação da imagem corporal para avaliar as variáveis que a influenciam – Índice de Massa Corporal (IMC), insatisfação com a imagem corporal e sintomas depressivos em mulheres eutróficas (n = 40) e com excesso de peso (n = 40). A avaliação da imagem corporal e dos sintomas depressivos foi conduzida por meio da Escala de Figuras de Silhuetas (EFS) e pelo Inventário de Depressão de Beck (BDI), em suas versões brasileiras, respectivamente. No grupo eutrófico, a insatisfação e a pontuação do BDI explicaram 55% e 12% da variação da estimação, respectivamente. No grupo com excesso de peso, a insatisfação com a imagem corporal foi responsável por 14% da variação da estimação da imagem corporal, enquanto o IMC, individualmente, por somente 9%. Quando avaliados em conjunto, esse percentual aumenta para 42%, indicando que juntos – IMC e insatisfação – agregam maior valor explicativo para essa variável. A insatisfação foi considerada a variável mais saliente, influenciando em maiores proporções os valores de estimação obtidos, particularmente entre as mulheres eutróficas.

Body Size Perception

<p>perception and dissatisfaction.  Though most research studies focus on adolescence and adulthood, dissatisfaction problems are manifesting themselves at increasingly early ages.  The aim of this study was, therefore, to analyse the most significant findings on body dissatisfaction and body-size perception among children aged 3 to 6 (second cycle of pre-school education).  To this end the Medline, SportDiscus, Scopus, ScienceDirect, Dialnet, ProQuest and EBSCO databases were used, and from which a total of 22 studies were selected in accordance with exclusion criteria such as language, peer review and the objective measurement of the body mass index (BMI) of children.  In terms of levels of dissatisfaction, results vary widely, making it impossible to draw sound conclusions on the nature and prevalence of this variable at these ages.  The main reasons for this include the type of instrument used and the difficulties children had in perceiving their bodies correctly.</p>

Perceptual Aspect

The literature is inundated with studies reporting the body image experiences of anorexia nervosa patients and normal weight people. Such studies have not, however, yielded consistent results. The present study reinvestigated the issue bearing in mind the theoretical and methodological limitations of previous research. The perceptual and affective aspects of body image were investigated in 11 white, female anorexic patients and 51 white, female psychology undergraduate university students. A combination of the movable caliper technique and image-marking procedure was used to assess body size perception, that is, the perceptual aspect, and the Body Cathexis scale was used to assess body satisfaction, that is, the affective aspect. It was found that anorexic females overestimate the width of their waist and thighs significantly more than normal females ( p < 0.05) and that they have a significantly lower body satisfaction ( p < 0.001). It was concluded that the DSM IV criterion of a disturbance in body image has specific diagnostic relevance in anorexia nervosa.

Background. The effective illusory ownership over an artificial body in modulating body representations in healthy and eating disorders population has been repeatedly reported in recent literature. In this study, we extended this research in the field of obesity: specifically, we investigated whether ownership over a virtual body with a skinny abdomen might be successfully experienced by participants affected by obesity. Methods. Fifteen participants with obesity and fifteen healthy-weight participants took part at this study in which the VR-Full-Body Illusion was adopted. The strength of illusion was investigated through the traditional Embodiment Questionnaire, while changes in bodily experience were measured through a body size estimation task. Results. Participants with obesity as well as healthy-weight participants reported to experience the illusion. About the body size estimation task, both groups reported changes only in the estimation of the abdomen’s circumference after the experimental condition, in absence of any another difference. Discussion. Participants with obesity reported to experience the illusion over a skinny avatar, but the modulation of the bodily experience seems controversial. Future lines of research exploiting this technique for modulating body representations in obesity, specifically in terms of potential therapeutic use, were discussed.

Body size estimation was studied in 22 patients with bulimia and 20 normal controls. Two methods of body size estimation were used, a distorting television image method (DTIM) and the image marking method (IMM). The subjects estimated body size of a dummy as well as their own body on the DTIM. When estimating body size on the DTIM the bulimics overestimated and the controls underestimated, there being a significant difference between the two groups. There was no difference between the groups when estimating the size of the dummy. On the IMM a significant difference was found between the bulimic and control groups, the bulimics overestimating body size and the controls being more accurate. Marked directional effects were found with the DTIM. The two methods of body size estimation are compared.

We asked 24 patients with anorexia nervosa and 30 normal controls to estimate their body-size several times, each time using different instructions. The degree of over-estimation was found to vary predictably with the wording of the instructions. Informing the subject that she had made an error without specifying the direction of the error resulted in reduced over-estimation on a subsequent trial, for both anorexics and controls. ‘Internally directed’ instructions were associated with a greater degree of over-estimation than ‘external’ instructions in both groups, but particularly in anorexic subjects. Our results indicate the necessity of controlling the ‘demand characteristics' of such experiments.
