Abstract

Intolerance of uncertainty (IU) is a cognitive factor linked to various mental health disorders, especially anxiety, in children and adolescents. This study aimed to adapt and validate the Intolerance of Uncertainty Index-A for Children (IUI-A-C) into Turkish. A sample of 552 participants aged 10 to 19 years (M = 13.84, SD = 2.29) completed the Turkish version of the IUI-A-C and measures of anxiety. The study assessed confirmatory factor analysis, internal consistency reliability, criterion validity, item discrimination, and test-retest reliability. The adapted scale showed good psychometric properties, with confirmatory factor analysis indicating a good fit to the data. Internal consistency reliability was adequate (Cronbach's α = .73), and criterion validity was supported by a moderate positive correlation with anxiety measures. Item discrimination analysis demonstrated the scale's ability to differentiate between high and low levels of IU, and test-retest reliability was excellent (intraclass correlation coefficient = .92). Thus, the Turkish IUI-A-C is a valid and reliable tool for assessing IU in children and adolescents.

儿童不确定性指数- a不耐受的土耳其适应和心理测量特征。

不确定性不耐受（IU）是一种认知因素，与儿童和青少年的各种精神健康障碍，特别是焦虑有关。本研究旨在将儿童不确定性指数- a （IUI-A-C）的不耐受度改编并验证为土耳其语。552名10至19岁的参与者（M = 13.84, SD = 2.29）完成了土耳其版IUI-A-C和焦虑测量。本研究评估了验证性因子分析、内部一致性信度、标准效度、项目区分度和重测信度。调整后的量表显示出良好的心理测量特性，验证性因子分析表明与数据吻合良好。内部一致性信度足够（Cronbach's α = .73），标准效度与焦虑测量有中度正相关。项目判别分析表明，该量表能够区分高水平和低水平的IU，重测信度极好（类内相关系数= 0.92）。因此，土耳其IUI-A-C是评估儿童和青少年IU的有效和可靠的工具。
