A Multidimensional Structure for Repetitive Thought: What's on Your Mind, and How, and How Much?

Although repetitive thought (RT) styles such as worry, rumination, and processing correlate positively, they have divergent effects on well-being, suggesting important dimensional variation. In Study 1, multidimensional scaling identified 2 dimensions-positive versus negative content valence and searching versus solving purpose-among students ( N = 978) who completed standard RT measures. In Study 2, students ( N = 100) sorted 25 descriptions of RT. Multidimensional scaling identified 4 dimensions, including valence and purpose. Content valence associated with valenced affect; solving associated with less aroused affect and less polarized appraisals of thought topics. In Study 3, valence and purpose of RT descriptions by women in a breast cancer prevention trial ( N = 62) predicted concurrent affect and psychological and physical well-being.
