OBJECTIVES
Body-weight norms may explain why personal evaluations of weight status are often inaccurate. Here, we tested a 'norm comparison' explanation of weight status perceptions, whereby personal evaluations of weight status are biased by perceived body-weight norms.
METHODS
Study 1 examined whether perceptions of how one's own body weight compares to an average person predict personal evaluations of weight status. Study 2 examined whether manipulating perceptions of how one's own body weight compares to an average person influences whether or not a person identifies their own weight status as being overweight.
RESULTS
In Study 1, if participants rated their body weight as being similar to the body weight of an average person, they were less likely to identify their weight status as being overweight. In Study 2, participants that were led to believe that their body weight was heavier than the average person were more likely to perceive their own weight status as being overweight.
CONCLUSIONS
Personal perceptions of weight status are likely to be shaped by a 'norm comparison' process. As overweight becomes more normal, underestimation of weight status amongst individuals with overweight and obesity will be more common.
目的
体重标准或许可以解释为何人们对自身体重状况的个人评估往往不准确。在此，我们测试了一种关于体重状况认知的“标准比较”解释，即个人对体重状况的评估会受到所感知的体重标准的影响。
方法
研究1检验了个人对自己体重与普通人相比情况的认知是否能预测其对体重状况的个人评估。研究2检验了操控个人对自己体重与普通人相比情况的认知是否会影响一个人是否将自己的体重状况认定为超重。
结果
在研究1中，如果参与者认为自己的体重与普通人的体重相似，他们将自己的体重状况认定为超重的可能性就较小。在研究2中，那些被引导认为自己体重比普通人重的参与者更有可能将自己的体重状况视为超重。
结论
个人对体重状况的认知可能受“标准比较”过程的影响。随着超重变得更为常见，超重和肥胖个体对体重状况的低估将会更为普遍。
