The current study evaluated the psychometric properties of Wiseman and Watt's (2004) negative and positive superstitious belief items. The original items were compared with a modified, reworded set of items which emphasized each item's relation with either good or bad luck, and standard psychometric analyses were done. Modifying the items did not improve their psychometric properties; there was a negligible effect on Cronbach alpha, and Positive Item 3 continued to perform poorly. Confirmatory factor analysis, using the maximum likelihood method, suggested that a two-factor solution was preferable to a one-factor solution for both the original and modified items and that the problematic item should be discounted. It was concluded that the items require development and refinement before firm conclusions can be made about the factorial structure of superstitious belief. These results should also be tested further using Rasch methods.
本研究评估了怀斯曼和瓦特（2004年）的消极和积极迷信信念项目的心理测量特性。将原始项目与一组经过修改、重新措辞的项目进行了比较，后者强调了每个项目与好运或厄运的关系，并进行了标准的心理测量分析。修改项目并没有改善其心理测量特性；对克朗巴哈系数的影响可以忽略不计，且积极项目3的表现仍然不佳。使用最大似然法的验证性因素分析表明，对于原始项目和修改后的项目，两因素解决方案比单因素解决方案更可取，并且有问题的项目应不予考虑。得出的结论是，在对迷信信念的因子结构得出确凿结论之前，这些项目需要进一步开发和完善。这些结果还应使用拉施方法进行进一步测试。
