This study developed a short form of the Attitudes and Beliefs Scale-2 (ABS-2), a measure of Ellis’s irrational and rational beliefs. We compared the short form (ABS2-SF) to the longer original scale with 2096 participants, including clinical outpatients, American and Romanian college students, and drug/alcohol rehab residents. The ABS-SF correlated highly with the Original ABS-2. Confirmatory Factor Analyses yielded an excellent fit for an eight-factor bifactor model with factors for the irrational and rational cognitive processes and a general factor. The resulting subscales had excellent internal reliability. The ABS2-SF were highly correlated with measures of mental health problems, and these correlations were significantly higher with the symptom distress subscale than with the troubled social relationships subscale. Correlations with screening measures for DSM-4 disorders showed that the correlations significant but higher for disorders that represented disturbed negative emotions such as anxiety and depression and less with disorders characterized by dysfunctional behaviors. The ABS2_SF scores were significantly higher in a clinical sample than in a college sample. The results have implications for future REBT research that assess irrational and rational beliefs and clinical implications for potentially targeting treatment.

这项研究开发了态度和信念量表2（ABS-2）的简短形式，该量表是埃利斯的非理性和理性信念的量度。我们将较短的表格（ABS2-SF）与更长的原始表格进行了比较，共有2096名参与者，包括临床门诊患者，美国和罗马尼亚大学生以及戒毒/戒酒的居民。ABS-SF与原始ABS-2高度相关。验证性因素分析非常适合八因素双因素模型，其中包括非理性和理性认知过程的因素以及一般因素。所得的分量表具有出色的内部可靠性。ABS2-SF与心理健康问题的测量高度相关，与症状困扰子量表相比，与患社交关系子量表的相关性更高。与DSM-4疾病筛查指标的相关性表明，相关性显着，但对于那些表现出不良的负面情绪（如焦虑和抑郁）的疾病，其相关性更高，而与以机能障碍为特征的疾病的相关性则较小。在临床样本中，ABS2_SF得分显着高于大学样本。该结果对将来的REBT研究具有影响，该研究评估了非理性和理性的信念以及对潜在靶向治疗的临床意义。
