目的：本研究考察了两个相关的和混淆的身体形象结构-高估和身体形象不满-并通过检验其与自尊和负面情绪变化的纵向关联来测试其独特性。方法：145个肥胖者（平均BMI = 51.6，SD = 7.5）患者（16名男性和129名女性）在接受胃旁路手术之前和之后6个月完成了一系列自我报告措施。身体形象的措施（高估的形状和重量，和身体形象的不满），自尊，和负面affect.Results：高估和身体形象的不满都大大改善手术后进行了评估。过度评价的变化仅与自尊的变化显著相关（在控制了负面影响之后）。而身体形象的变化不满意显着相关的变化，在自尊和负面影响;结果偏相关性保持不变Conclusion：这些研究结果表明，评价自己的形状和重量有关，但不一样，不满意的形状和重量。鉴于过度评价不太可能受到情绪的影响，它似乎是一个更稳定的标志，在身体形象的干扰比身体形象的不满。这种区别对于临床医生和研究人员如何评估这些结构具有重要意义。(c)出版社：Wiley Periodicals，Inc.
Objective: This study examined two related and confused body image constructs-overevaluation and body image dissatisfaction-and tested their distinctiveness by examining their longitudinal associations with changes in self-esteem and negative affect.Method: One hundred forty-five obese (mean BMI = 51.6, SD = 7.5) patients (16 men and 129 women) completed a battery of self-report measures prior to and six months after undergoing gastric bypass surgery. Measures of body image (overevaluation of shape and weight, and body image dissatisfaction), self-esteem, and negative affect were assessed.Results: Overevaluation and body image dissatisfaction both improved substantially following surgery. Change in overevaluation was significantly correlated only with change in self-esteem (after controlling for negative affect). Whereas change in body image dissatisfaction was significantly correlated with changes in both self-esteem and negative affect; findings for partial correlations remained unchanged.Conclusion: These findings demonstrate that evaluating oneself by shape and weight is related to, but not the same as, being dissatisfied about shape and weight. Given that overevaluation is less likely to be influenced by mood, it appears to be a more stable marker for disturbance in body image than body image dissatisfaction. This distinction has important implications for how clinicians and researchers assess these constructs. (c) 2006 by Wiley Periodicals, Inc.
