The high degree of comorbidity among mental disorders has generated interest in identifying transdiagnostic processes associated with multiple types of psychopathology. Susan Nolen-Hoeksema conceptualized rumination as one such transdiagnostic process associated with depression, anxiety, substance abuse, binge eating, and self-injurious behavior. The degree to which rumination accounts for the ...

While there are several studies that have investigated the specific relationships between mindfulness, anger rumination, anger-in, and trait anger, no study has investigated all these relationships simultaneously. Therefore, this study examined all relationships between these variables employing a cross-sectional design. Consistent with previous research, we hypothesized that (1) mindfulness wi...

The current report aimed to document individual differences that predict the trajectory of post-event rumination following an evaluative event. In this study, 127 undergraduate students were assessed over a 5-day period preceding and following a mid-term exam. Participants completed measures of anticipatory processing, trait test anxiety, trait tendency to ruminate, negative affect, and post-ev...

Rumination has been suggested to be an important factor maintaining posttraumatic stress disorder (PTSD). Using an analogue design, this study aimed to experimentally test the hypothesis that trauma-related rumination maintains PTSD symptoms. Fifty-one participants were first asked to give a detailed narrative of a negative life event and were then randomly assigned to a rumination or distracti...

Mounting research shows that the tendency to co-ruminate with peers regarding ongoing problems increases adolescents' depression risk; however, the means by which this interpersonal process fosters risk has not been identified. This said, theorists have proposed that co-rumination increases depression risk, in part, by increasing one's tendency to ruminate when alone. We tested this hypothesis ...

Self-focused, analytical mental rumination constitutes a central process in depression. It has been hypothesized that such rumination depletes executive resources that are necessary for an efficient cognitive regulation of emotion and behavior. However, most of the research supporting this hypothesis is of correlational nature. The present study examined the effects of induced rumination versus...

Recently, cross-sectional research has demonstrated that depressive rumination is significantly associated with the tendency to engage in cognitive and behavioral avoidance. This evidence suggests that rumination may be the result of attempts to avoid personally threatening thoughts, in a manner suggested by multiple contemporary theories of worry. This investigation examined the temporal relat...

Co-rumination, defined as repetitive, problem-focused talk explains higher levels of friendship quality in youth (Rose, 2002) and increased levels of anxiety/depression in females. Middle adolescents (N = 146) participated in a study of co-rumination, individual coping, externalizing/internalizing problems, and peer functioning. Consistent with past research, girls reported higher levels of co-...

In 3 studies, the authors investigated whether within-persons increases in rumination about an interpersonal transgression were associated with within-persons reductions in forgiveness. Results supported this hypothesis. The association of transient increases in rumination with transient reductions in forgiveness appeared to be mediated by anger, but not fear, toward the transgressor. The assoc...

Despite the enormous costs associated with unrestrained anger, little is known about the neural mechanisms underlying anger regulation. Behavioral evidence supports the effectiveness of reappraisal in reducing anger, and demonstrates that rumination typically maintains or augments anger. To further understand the effects of different anger regulation strategies, during functional magnetic reson...
