Rumination has been associated with depression and negative health effects. Yet measures of rumination appear to index multiple constructs that may be differentially related to clinical phenomena. To clarify this literature, we explored convergence and divergence among self-report measures of rumination in 349 undergraduates, 59 depressed adults, 81 healthy adults, and 15 never-depressed adults with Systemic Lupus Erythematosis (SLE). Results suggested there are separate constructs labeled rumination with different relationships to depression. Yet, aggregate measures index a central construct. Depressed individuals ruminated more, across measures, than individuals with SLE, who ruminated more than healthy individuals; this relationship was mediated by dysphoria. Thus, administering multiple rumination measures and attending to constructs assessed by rumination measures appears important in clinical studies.
