Discrete forms of repetitive thought (RT), such as worry and reflection, can be characterized along basic dimensions of valence (positive vs. negative) and purpose (searching vs. solving). In addition, people can be characterized as high or low in their tendency to engage in RT. This dimensional model has been demanding to assess, and a smaller number of items that could stand in for a large battery would make measurement more accessible. Using four samples (N = 1,588), eight items that assess RT valence, purpose, and total in a circumplex model were identified. Across these and other samples, the dimensions were adequately reliable and valid with regard to assessment via large RT battery, other measures of RT, and depressive symptoms. The accessibility of dimensional assessment of RT using this smaller number of items should facilitate work on questions about the qualities of RT that predict mental and physical health.
离散形式的重复性思维（RT），如担忧和反思，可以根据效价（积极与消极）和目的（探索与解决）的基本维度来描述。此外，人们参与重复性思维的倾向可分为高或低。这个维度模型一直难以评估，而较少数量的项目能够替代大量的测试项目，将使测量更易于进行。通过四个样本（N = 1,588），确定了在环性模型中评估重复性思维效价、目的和总量的八个项目。在这些样本和其他样本中，就通过大量重复性思维测试项目、重复性思维的其他测量方法以及抑郁症状进行的评估而言，这些维度具有足够的可靠性和有效性。使用较少数量的项目对重复性思维进行维度评估，应有助于研究预测身心健康的重复性思维特质相关问题。
