The role of cognitive processes and personality traits in different types of rumination

Kimberly K Seriki, Purdue University

Abstract

The current study examined predictors of two types of rumination, dysphoric rumination and anger rumination, in a non-clinical sample of 186 college students. Existing studies of dysphoric rumination propose linkages to negative mental health outcomes, most notably Major Depression (Goldstein, 2006; Just & Alloy, 1997; Nolen-Hoeksema, 1987, 1991). Less is known about anger rumination but it has been positively linked to objective and subjective reports of aggression (Maxwell, Sukhodolsky, & Chow, 2005). The overall goals of the current study were to explore the relationship between the two types of rumination by examining how they each relate to mindfulness, thought suppression, coping, personality, and gender. Using a two-scale measure of dysphoric rumination (Treynor et al., 2003), between group analyses revealed more mindful individuals reported less brooding but just as much reflection than their less mindful peers. More mindful individuals also reported lower levels of anger rumination. A similar link between thought suppression and anger rumination was found. There was partial support for role of coping skills in decreasing propensity for either type of rumination. These results are discussed. Dysphoric and anger rumination appeared to have some predictors in common, however, future research is needed with larger and more diverse samples to draw firm conclusions. The complex link between rumination, depression, and personality was discussed along with the need for measurement refinement.
