Magical thinking has been proposed to have an aetiological role in obsessive compulsive disorder (OCD).
To address the limitations of existing measures of magical thinking we developed and validated a new 24-item measure of magical thinking, the Illusory Beliefs Inventory (IBI).
The validation sample comprised a total of 1194 individuals across two samples recruited via an Internet based survey.
Factor analysis identified three subscales representing domains relevant to the construct of magical thinking: Magical Beliefs, Spirituality, and Internal State and Thought Action Fusion. The scale had excellent internal consistency and evidence of convergent and discriminant validity. Evidence of criterion-related concurrent validity confirmed that magical thinking is a cognitive domain associated with OCD and is largely relevant to neutralizing, obsessing and hoarding symptoms.
It is important for future studies to extend the evidence of the psychometric properties of the IBI in new populations and to conduct longitudinal studies to examine the aetiological role of magical thinking.
神奇思维被认为在强迫症（OCD）中有病因作用。
为了解决现有神奇思维测量方法的局限性，我们开发并验证了一种新的 24 项神奇思维测量方法，即错觉信念量表（Illusory Beliefs Inventory，IBI）。
验证样本由通过互联网调查招募的两个样本中的总共 1194 名个体组成。
因素分析确定了三个代表与神奇思维结构相关的领域的子量表：神奇信念、灵性和内部状态与思维行动融合。该量表具有极好的内部一致性和收敛与区分效度的证据。与标准相关的同时效度证据证实，神奇思维是与 OCD 相关的认知领域，主要与中和、强迫和囤积症状相关。
未来的研究在新的人群中扩展 IBI 的心理测量特性的证据，并进行纵向研究以检验神奇思维的病因作用是很重要的。
