Is there an association between rumination and self-reported physical health? A one-year follow-up in a young and an elderly sample.

Cross-sectional studies have suggested an association between rumination and subjective health. The aim of the present study was to investigate in a longitudinal design whether rumination was related to self-reported physical health. A total of 96 young (age range 20-35) and 110 elderly (age range 70-85) participants completed questionnaires measuring rumination, negative affect, life events, and self-reported physical health at baseline and at 1-year follow-up. Multiple linear regressions showed a significant association between self-reported physical health at time I only for the elderly and negative affect mediated the association. At follow-up, rumination was significantly associated with self-reported physical health only for the young and the association was only partly mediated by negative affect. In conclusion, rumination is associated with poorer self-reported physical health, but the association depends on the age of the individual as well as time span studied.
