In this article, we develop the revised and short versions of the pseudoscientific belief scale through two empirical studies (N = 4154). This revision is motivated by the excessive length of the scale, as well as by consistent observations of poor item loadings across several studies. Exploratory factor analysis in Study 1 revealed 11 dispensable items, resulting in a 19‐item revised form, whereas in Study 2 we constructed a short eight‐item form. Confirmatory factor analysis revealed unidimensional factor structures for both scales, exhibiting excellent psychometric properties in relation to factor structure, item loadings, internal consistency and convergent validity with paranormal beliefs, conspiracy theories and need for uniqueness. Whereas the original scale provides reliable indices, we encourage the use of these improved versions to measure pseudoscientific beliefs in the context of socio‐psychological studies.

伪科学信念量表的修订版和简短版

在本文中，我们通过两次实证研究（N= 4154）。修订的动机是由于量表的长度过长，以及在数项研究中一致观察到不良的物品装载量。研究1中的探索性因素分析揭示了11个可有可无的项目，从而形成了19个项目的修订表格，而研究2中，我们构建了一个简短的8个项目表格。验证性因素分析揭示了两个尺度的一维因素结构，与因素结构，项目负荷，内部一致性和具有超自然信念，共谋理论和独特性的收敛效度有关，表现出出色的心理计量学特性。尽管原始量表提供了可靠的指标，但我们鼓励在社会心理学研究的背景下使用这些改进的版本来衡量伪科学信念。
