Briefly Assessing Repetitive Thought Dimensions: Valence, Purpose, and Total.

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.
