Few studies exist that examine risk factors for the overvalued ideas about the personal implications of body shape and weight that are viewed as the central cognitive substrate of eating disorders.
In a female adolescent population (mean age = 14 years, SD = 0.7), we examine variables previously identified in the literature as risk factors for eating disorders, namely, self-esteem, comments from others about eating/weight/shape, perfectionism, childhood and parental weight/shape, and parental conflict.
These variables were all correlated significantly with current (past 4 weeks) levels of overvalued ideas and disturbed eating patterns in the predicted directions. Self-esteem was found to mediate partially the relationship between the overvalued ideas and comments about weight and perfectionism. Self-esteem fully mediated the relationship between the overvalued ideas and parental conflict. A family index of body size had an independent influence on the overvalued ideas, that is, the bigger the size, the greater the overvalued ideas. Finally, the overvalued ideas fully accounted for the relationship between self-esteem and disturbed eating patterns.
The cognitive model of bulimia nervosa is supported by the results of this study. Self-esteem represents an important gateway to the overvalued ideas that contribute substantially to disturbed eating patterns.
很少有研究探讨对体型和体重个人影响的高估观念的风险因素,而这些观念被视为饮食失调的核心认知基础。
在一个女性青少年群体(平均年龄 = 14岁,标准差 = 0.7)中,我们研究了文献中先前确定的饮食失调风险因素变量,即自尊、他人关于饮食/体重/体型的评论、完美主义、童年及父母的体重/体型,以及父母冲突。
这些变量均与当前(过去4周)高估观念水平和紊乱饮食模式在预测方向上显著相关。自尊被发现部分介导了高估观念与关于体重和完美主义的评论之间的关系。自尊完全介导了高估观念与父母冲突之间的关系。家庭体型指数对高估观念有独立影响,即体型越大,高估观念越强。最后,高估观念完全解释了自尊与紊乱饮食模式之间的关系。
本研究结果支持神经性贪食症的认知模型。自尊是导致对饮食模式产生重大干扰的高估观念的重要途径。
