Catastrophizing is a cognitive process that can be defined as predicting the worst possible outcome. It has been shown to be related to psychiatric diagnoses such as depression and anxiety, yet there are no self-report questionnaires specifically measuring it outside the context of pain research. Here, we therefore develop a novel, comprehensive self-report measure of general catastrophizing. We performed five online studies (total = 734), in which we created and refined a Catastrophizing Questionnaire, and used a factor analytic approach to understand its underlying structure. We also assessed convergent and discriminant validity, and analysed test-retest reliability. Furthermore, we tested the ability of Catastrophizing Questionnaire scores to predict relevant clinical variables over and above other questionnaires. Finally, we also developed a four-item short version of this questionnaire. We found that our questionnaire is best fit by a single underlying factor, and shows convergent and discriminant validity. Exploratory factor analyses indicated that catastrophizing is independent from other related constructs, including anxiety and worry. Moreover, we demonstrate incremental validity for this questionnaire in predicting diagnostic and medication status. Finally, we demonstrate that our Catastrophizing Questionnaire has good test-retest reliability (intraclass correlation coefficient = 0.77, < 0.001). Critically, we can now, for the first time, obtain detailed self-report data on catastrophizing.
灾难化思维是一种认知过程，可定义为预测最糟糕的可能结果。研究表明，它与抑郁症和焦虑症等精神疾病诊断有关，但在疼痛研究背景之外，尚无专门测量它的自我报告问卷。因此，我们在此开发了一种全新的、全面的一般灾难化思维自我报告测量方法。我们进行了五项在线研究（共734人），创建并完善了灾难化思维问卷，并采用因素分析方法来理解其潜在结构。我们还评估了聚合效度和区分效度，并分析了重测信度。此外，我们测试了灾难化思维问卷得分在预测相关临床变量方面相对于其他问卷的能力。最后，我们还开发了该问卷的一个四项简短版本。我们发现，我们的问卷最适合单一潜在因素，具有聚合效度和区分效度。探索性因素分析表明，灾难化思维独立于其他相关结构，包括焦虑和担忧。此外，我们证明了该问卷在预测诊断和用药状况方面具有增量效度。最后，我们证明我们的灾难化思维问卷具有良好的重测信度（组内相关系数 = 0.77，< 0.001）。至关重要的是，我们现在首次能够获得关于灾难化思维的详细自我报告数据。
