Self-reported height and weight data are commonly reported within eating disorders research. The aims of this study are to demonstrate the accuracy of self-reported height and weight and to determine whether that accuracy is associated with levels of eating psychopathology among a group of young nonclinical women.
One hundred and four women were asked to report their own height and weight. They then completed the Eating Disorders Examination-Questionnaire. Finally, they were weighed and their height was measured in a standardized manner. Accuracy scores for height and weight were calculated by subtracting their actual weight and height from their self-reports.
Overall, the women overestimated their heights and underestimated their weights, leading to significant errors in body mass index where self-report is used. Those women with high eating concerns were likely to overestimate their weight, whereas those with high weight concerns were more likely to underestimate it.
These data show that self-reports of height and weight are inaccurate in a way that skews any research that depends on them. The errors are influenced by eating psychopathology. These findings highlight the importance of obtaining objective height and weight data, particularly when comparing those data with those of patients with eating disorders.
在饮食失调研究中,通常会报告自我报告的身高和体重数据。本研究的目的是证明自我报告身高和体重的准确性,并确定该准确性是否与一组年轻非临床女性的饮食心理病理学水平相关。
104名女性被要求报告自己的身高和体重。然后她们完成了饮食失调检查问卷。最后,对她们进行称重,并以标准化方式测量身高。身高和体重的准确性得分通过从自我报告中减去实际体重和身高来计算。
总体而言,这些女性高估了自己的身高,低估了自己的体重,导致在使用自我报告时体重指数出现显著误差。那些饮食问题严重的女性可能高估自己的体重,而那些体重问题严重的女性更可能低估体重。
这些数据表明,身高和体重的自我报告不准确,会使任何依赖它们的研究产生偏差。这些误差受饮食心理病理学影响。这些发现凸显了获取客观身高和体重数据的重要性,尤其是在将这些数据与饮食失调患者的数据进行比较时。
