To assess the relationship between body size estimation on the one hand and clinical and psychological variables on the other.
Body size estimation was tested with the video distortion method on a life-size screen in normal women (n = 45) and compared to a total of 189 female eating disorder patients (100 with restricting anorexia nervosa, 41 with binging/purging anorexia nervosa, 48 with bulimia nervosa). The subjects' cognitive responses (what they think they really look like), affective responses (what they feel they look like), and optative responses (what they want to look like) were correlated with clinical parameters (including body composition) and with the scores on a series of self-report questionnaires assessing general psychological well-being and body experience.
No significant relationship was found between the body size estimations and the clinical variables. The cognitive and affective responses showed a moderate relationship with self-reported body attitude. Body dissatisfaction was negatively correlated with the optative response (desired body size).
This study contributes to the construct validity of the video distortion method. Body size estimation includes more than just a perceptual task. Hence, the narrow notion of body image should be replaced by the more complex construct of "body experience," the multidimensionality of which should be addressed in both research and treatment of eating-disordered patients.
一方面评估身体大小估计与另一方面临床及心理变量之间的关系。
采用视频变形法在真人大小的屏幕上对正常女性（n = 45）进行身体大小估计测试，并与总共189名女性饮食失调患者（100名节食型神经性厌食症患者、41名暴饮暴食/清除型神经性厌食症患者、48名神经性贪食症患者）进行比较。将受试者的认知反应（她们认为自己实际的样子）、情感反应（她们感觉自己的样子）和期望反应（她们想要的样子）与临床参数（包括身体成分）以及一系列评估总体心理健康和身体体验的自我报告问卷得分进行关联。
未发现身体大小估计与临床变量之间存在显著关系。认知和情感反应与自我报告的身体态度呈中等程度的关系。身体不满与期望反应（期望的身体大小）呈负相关。
本研究有助于视频变形法的结构效度。身体大小估计不仅仅是一项感知任务。因此，身体形象的狭义概念应由更复杂的“身体体验”结构所取代，在饮食失调患者的研究和治疗中都应考虑其多维度性。
