Mood-as-input hypothesis is a theory of task perseveration that has been applied to the understanding of perseveration across psychopathologies such as pathological worrying, compulsive checking, depressive rumination, and chronic pain. We review 10 years of published evidence from laboratory-based analogue studies and describe their relevance for perseveration in clinical populations. In particular, mood-as-input hypothesis predicts that perseveration at a task will be influenced by interactions between the individual's stop rules for the task and their concurrent mood, and that the valency of an individual's concurrent mood is used as information about whether the stop rule-defined goals for the task have been met. The majority of the published research is consistent with this hypothesis, and we provide evidence that clinical populations possess characteristics that would facilitate perseveration through mood-as-input processes. We argue that mood-as-input research on clinical populations is long overdue because (1) it has potential as a transdiagnostic mechanism helping to explain the development of perseveration and its comorbidity across a range of different psychopathologies, (2) it is potentially applicable to any psychopathology where perseveration is a defining feature of the symptoms, and (3) it has treatment implications for dealing with clinical perseveration.
心境输入假说（Mood-as-input hypothesis）是一种任务坚持的理论，已被应用于理解各种精神病理学中的坚持，如病理性担忧、强迫性检查、抑郁性反刍和慢性疼痛。我们回顾了 10 年来基于实验室的模拟研究的发表证据，并描述了它们对临床人群中坚持的相关性。特别是，心境输入假说预测，任务的坚持将受到个体任务停止规则与他们当前心境之间的相互作用的影响，并且个体当前心境的效价被用作关于任务停止规则定义的目标是否已经达到的信息。已发表的大多数研究都与该假说一致，并且我们提供了证据表明，临床人群具有通过心境输入过程促进坚持的特征。我们认为，对临床人群进行心境输入研究是非常必要的，因为：（1）它作为一种跨诊断机制具有潜力，可以帮助解释坚持的发展及其在一系列不同精神病理学中的共病；（2）它可能适用于任何以坚持为症状特征的精神病理学；（3）它对处理临床坚持具有治疗意义。
