The present paper reports the results of two experiments designed to test some predictions from a mood-as-input explanation of catastrophic worrying (). In particular, these experiments attempted to identify whether worriers possess characteristics that would contribute to the use of relatively strict 'as many as can' closure rules for catastrophising. Experiment 1 demonstrated that high worriers begin a catastrophising task with higher self-reported levels of responsibility towards fully considering all issues involved, than low worriers. Experiment 2 suggested that inflated responsibility has a causal effect on perseveration at the catastrophising task (rather than being a simple non-causal by-product of excessive worrying), and that inflated responsibility exacerbates catastrophising only in conjunction with negative mood. This suggests a relatively complex relationship between responsibility and mood, where there are mood conditions in which high responsibility does not generate greater persistence than low responsibility. These findings are consistent with predictions from a mood-as-input account of catastrophic worrying, and provide evidence for a putative mechanism that mediates the influence of variables such as inflated responsibility on perseveration.
本文报告了两项实验的结果，这两项实验旨在检验关于灾难性担忧的情绪输入解释的一些预测（）。具体而言，这些实验试图确定担忧者是否具备有助于使用相对严格的“尽可能多”的灾难化闭合规则的特征。实验1表明，与低担忧者相比，高担忧者在开始灾难化任务时，自我报告的对充分考虑所有相关问题的责任感水平更高。实验2表明，夸大的责任感对在灾难化任务中的执着有因果效应（而不是过度担忧的简单非因果副产品），并且夸大的责任感仅在与消极情绪相结合时才会加剧灾难化。这表明责任感和情绪之间存在相对复杂的关系，在某些情绪条件下，高责任感并不会比低责任感产生更大的执着。这些发现与灾难性担忧的情绪输入解释的预测一致，并为一种假定的机制提供了证据，该机制介导了诸如夸大的责任感等变量对执着的影响。
