The present study proposes a contextual specific, short measure of irrational and rational beliefs in order to provide a methodologically rigorous investigation of the REBT theoretical model. The COVID-19 Pandemic- Related Irrational and Rational Beliefs Scale was developed according with the REBT theory including rationally and irrationally worded items for each of the four cognitive processes. The data were collected online via google forms between March and June 2020, the sample comprised 798 individuals. A series of confirmatory factor analysis was conducted to investigate the factor structure of the scale. A total of seven measurement models representing different hypotheses about the structural relationship between the 32 items were estimated. Among the seven competing models, the eight-factor bifactor model comprising eight cognitive processes of irrational and rational beliefs factors and a general factor showed the best trade-of between model fit and complexity among all models. This model is congruent with the current theoretical formulation of REBT. The irrational cognitive processes themselves were highly correlated and the rational cognitive processes were moderately to highly correlate with each other. The concurrent validity was investigated and the results supported the validity of the instrument. Implications for research and clinical practice are discussed.

本研究提出了一种针对非理性和理性信念的具体情境的短期衡量标准，以便对 REBT 理论模型进行方法论上的严格研究。COVID-19大流行相关的非理性和理性信念量表是根据REBT理论开发的，包括针对四种认知过程中每一种的理性和非理性措辞项目。这些数据是在 2020 年 3 月至 6 月期间通过谷歌表格在线收集的，样本包括 798 人。通过一系列验证性因子分析来研究量表的因子结构。总共评估了 7 个测量模型，代表了 32 个项目之间结构关系的不同假设。在七个竞争模型中，由非理性和理性信念因素的八个认知过程和一个一般因素组成的八因素双因素模型显示了所有模型中模型拟合度和复杂性之间的最佳权衡。该模型与当前 REBT 的理论表述一致。非理性认知过程本身高度相关，而理性认知过程彼此中度至高度相关。研究了同时效度，结果支持了该工具的有效性。讨论了对研究和临床实践的影响。
