Defining body deception and its role in peer based social comparison theories of body dissatisfaction

The purpose of the current study was to operationalize the phenomenon of body deception, describe its theoretical importance, and validate its existence in an experimental paradigm. The definition of body deception includes the intentional misrepresentation of information about appearance to others. The present study examined body deception in a controlled experimental study of male and female same-sex peer groups using a series of hierarchical linear models. Ninety male and 90 female undergraduates were randomized to an experimental same-sex peer group or individual control condition. The results suggested that both men and women used body deception among peers, but men's body deception was muscularity driven whereas women's was thinness driven. Body dissatisfaction was significantly predictive of the degree of body deception used by both genders and it was significantly related to peer group membership. An integrated model for the role of body deception in body image disturbance is proposed.     

青少年身体不满意与自杀意念的关系:一个有调节的中介模型

为考察青少年对身体的满意度和自杀意念的关系，探讨自尊是否在青少年身体不满意和自杀意念的关系中起中介作用，以及这个过程是否受到友谊质量的调节作用。采用身体不满意量表、自杀意念量表、自尊量表和友谊质量量表对来自湖北、安徽、河南、吉林四省六所高中的802名高一学生进行调查，结果显示：（1）身体不满意对自杀意念具有显著的正向预测作用；（2）自尊在身体不满意和自杀意念的关系中起部分中介作用；（3）友谊质量在身体不满意通过自尊影响自杀意念的中介模型后半段起调节作用，即在友谊质量较低的青少年中，自尊对自杀意念的影响更大。因此，青少年身体不满意和自杀意念之间存在有调节的中介效应。
