This study aimed to investigate the validity and reliability of the Korean version of the Brief Irritability Test (BITe) and adapt it for Korean patients with psychiatric disorders.
A total of 296 patients at the Department of Psychiatry of Hanyang University Guri Hospital completed the BITe, Korean Beck Depression Inventory-II, Korean Beck Anxiety Inventory, the Korean version of the State-Trait Anger Expression Inventory, and Barratt Impulsiveness Scale-11. Construct validity was confirmed through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Reliability testing included assessments of internal consistency (Cronbach's α) and item-total correlations. Convergent validity was examined through correlational analyses with variables such as anxiety, depression, anger, and impulsivity.
First, the scale had good internal consistency with a Cronbach's α of 0.88. Second, EFA indicated a single dimensionality of the BITe, and CFA demonstrated a reasonable fit for the single-factor model (comparative fit index=0.97, Tucker-Lewis Index=0.95, normed fit index=0.97, goodness-of-fit index=0.96, root mean square error of approximation=0.12, standardized root mean residual=0.03). Finally, the convergent validity analysis revealed a significant positive correlation with depression, anxiety, and anger, except for anger control, which is a sub-variable of anger.
The results showed that the Korean version of the BITe had good psychometric properties, and might serve as a valuable tool for assessing irritability in Korean patients with psychiatric disorders.
本研究旨在探讨韩文版简短激惹性测试（BITe）的有效性和可靠性，并使其适用于患有精神疾病的韩国患者。
汉阳大学九里医院精神科的296名患者完成了BITe、韩文版贝克抑郁量表第二版、韩文版贝克焦虑量表、韩文版状态-特质愤怒表达量表和巴拉特冲动性量表-11。通过探索性因素分析（EFA）和验证性因素分析（CFA）来确认结构效度。可靠性测试包括内部一致性评估（克朗巴哈α系数）和项目与总分的相关性评估。通过与焦虑、抑郁、愤怒和冲动性等变量的相关分析来检验收敛效度。
首先，该量表具有良好的内部一致性，克朗巴哈α系数为0.88。其次，EFA表明BITe具有单维度性，CFA表明单因素模型拟合良好（比较拟合指数=0.97，塔克-刘易斯指数=0.95，规范拟合指数=0.97，拟合优度指数=0.96，近似误差均方根=0.12，标准化残差均方根=0.03）。最后，收敛效度分析显示，除了作为愤怒子变量的愤怒控制外，与抑郁、焦虑和愤怒均呈显著正相关。
结果表明，韩文版BITe具有良好的心理测量学特性，可能是评估韩国精神疾病患者激惹性的一个有价值的工具。
