The distinctiveness and relative clinical significance of overvaluation, dissatisfaction, and preoccupation with body weight/shape remains inconclusive. This study sought to add to the evidence by testing associations between these three body image constructs and indicators of clinical significance.
Male and female secondary students (N = 1,666) aged 12-18 years completed a survey that included measures of dissatisfaction with, overvaluation of, and preoccupation with weight/shape, psychological distress, eating disorder behaviors, and basic demographic information. Conditional process analysis was employed to test the independent and mediating effects of overvaluation, dissatisfaction, and preoccupation on distress, dietary restraint, and objective binge eating.
Overvaluation, dissatisfaction, and preoccupation were highly correlated (r = 0.47-0.84). In girls, preoccupation demonstrated the strongest independent and mediating effects on distress, dietary restraint, and binge eating; whereas neither the direct or indirect effects of dissatisfaction on distress and overvaluation on binge eating were significant. Among boys however, the direct and indirect effects of overvaluation, dissatisfaction, and preoccupation on distress and eating disorder behaviors were relatively equal.
Preoccupation with weight/shape may be particularly clinically significant in girls, whereas all constructs of body image disturbance may be equally clinically significant in boys. The findings are consistent with the view that these constructs, while closely related, are distinct. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:118-126).
对体重/体型的过度重视、不满及关注的独特性和相对临床意义尚无定论。本研究旨在通过检验这三种身体意象构念与临床意义指标之间的关联来补充相关证据。
12至18岁的男女中学生(N = 1666)完成了一项调查,其中包括对体重/体型的不满、过度重视及关注、心理困扰、饮食失调行为和基本人口统计学信息的测量。采用条件过程分析来检验过度重视、不满及关注对困扰、饮食限制和客观暴饮暴食的独立及中介作用。
过度重视、不满及关注高度相关(r = 0.47 - 0.84)。在女孩中,关注对困扰、饮食限制和暴饮暴食表现出最强的独立及中介作用;而不满对困扰的直接或间接作用以及过度重视对暴饮暴食的直接或间接作用均不显著。然而在男孩中,过度重视、不满及关注对困扰和饮食失调行为的直接及间接作用相对相当。
对体重/体型的关注在女孩中可能具有特别的临床意义,而身体意象紊乱的所有构念在男孩中可能具有同等的临床意义。这些发现与以下观点一致,即这些构念虽然密切相关,但却是不同的。© 2016威利期刊公司(《国际进食障碍杂志》2017年;50:118 - 126)
