Body dysmorphic disorder (BDD) is characterized by severe dissatisfaction with one's appearance. The aim of this study was to examine belief characteristics in BDD, particularly delusional beliefs and their relationship to other cognitive styles.
Fourteen DSM-IV BDD patients and 14 matched control participants completed questionnaires that measured delusions, creative experiences, self-esteem, self-ambivalence, depression and anxiety symptoms.
BDD patients endorsed three times as many delusional beliefs as controls, but the number of delusional ideas in the BDD sample was on a continuum and did not divide patients into two discrete groups. Additionally, the BDD group had higher fantasy proneness, lower self-esteem, higher self-ambivalence and higher depression and anxiety.
The data support the conceptualization of BDD as a single disorder with varying degrees of delusional thinking and suggests that BDD should not be dichotomized according to the presence or absence of delusional thinking, as is currently the case in the DSM-IV.
体象障碍（BDD）的特征是对自身外表的严重不满。本研究旨在探讨 BDD 中的信念特征，特别是妄想信念及其与其他认知风格的关系。
14 名 DSM-IV BDD 患者和 14 名匹配的对照组参与者完成了问卷，该问卷测量了妄想、创造性体验、自尊、自我矛盾、抑郁和焦虑症状。
BDD 患者的妄想信念是对照组的三倍，但 BDD 样本中的妄想数量是连续的，并没有将患者分为两个离散的组。此外，BDD 组的幻想倾向更高，自尊更低，自我矛盾更高，抑郁和焦虑程度更高。
数据支持将 BDD 概念化为一种具有不同程度妄想思维的单一障碍，并表明 BDD 不应该根据是否存在妄想思维来进行二分法，就像目前 DSM-IV 中的情况一样。
