尽管广泛使用，但不确定性不容忍量表简表（IUS-12）的翻译很少，并且在意大利对其心理测量特性的研究也很有限。此外，最近的证据表明该规模存在多方面的层次结构。我们将双因素模型与二阶和双因素模型进行了比较，其中假设了一般 IU 因素和两个更窄的因素：预期 IU 和抑制 IU。模型在单独参加 IUS-12 或与其他 IUS-27 项目的学生 (N = 609) 的汇总数据集上进行了测试。双因素模型比其他模型更适合样本数据。一般因素占项目方差的80%。呈现模式不会影响标量不变性。总分中，神经质、封闭需要和不确定性反应量表的收敛效度较高。因此，在临床研究和评估中建议采用IUS-12总分进行评分。
Despite widespread use, few translations are available for the Intolerance of Uncertainty Scale short form (IUS-12) as well as limited research on its psychometric properties in Italy. Moreover, recent evidence has suggested a multifaceted hierarchical structure for this scale. We compared the two-factor model to second-order and bi-factor models, in which a General IU factor was posited with two more narrow factors: Prospective IU and Inhibitory IU. Models were tested on a pooled dataset of students (N = 609) taking the IUS-12 alone or with other IUS-27 items. The bi-factor model fitted the sample data better than alternative models. The general factor accounted for 80% of the item variance. Presentation mode did not impact scalar invariance. Convergent validity with neuroticism, need for closure, and the uncertainty response scale was high for the total score. As such, scoring the IUS-12 total score is recommended in clinical research and assessment.
