Aberrant DMN connectivity and activity have been robustly linked to Major Depressive Disorder (MDD) risk for depression. This link has mostly explained in terms of rumination, a form negative, repetitive cognitive processing. Yet, accumulating findings are indicating altered dynamics during emotional processing MDD, pointing at potential emotion-related pathology depression inflexibly sustained...

The current longitudinal study tested hypotheses about Nolen-Hoeksema's (1987, 1991) response styles theory (RST) of depression in a sample of child and adolescent public school students. Wave 1 measures of rumination, distraction, and depression were obtained 6 months prior to the 2010 Nashville flood. Similar measures plus a measure of flood-related stressors were administered at Wave 2, appr...

Depressive rumination - a central characteristic of Major Depressive Disorder (MDD) - is a maladaptive emotion regulation strategy that prolongs sad mood and depressive episodes. Considerable research demonstrates the emotional and behavioral consequences of depressive rumination, yet few studies investigate its effect on neuroendocrine functioning. The current study examined the effect of an e...

according to the response styles theory (Nolen-hoeksema, 1991), rumination contributes to both the development and maintenance of depressive symptoms. in this study, we examined the vulnerability and maintenance hypotheses in a multi-wave prospective study of young adults with levels of negative events and depressive symptoms assessed every week for 7 weeks. We found no support for the vulnerab...

OBJECTIVE The study addressed the hypothesis that adults reporting sexual abuse are more likely to exhibit a general tendency to ruminate on sadness. The relations between reported abuse, rumination on sadness, and dysphoria were also examined. METHOD Undergraduate students (101 women and 100 men) reported on childhood and adult sexual abuse and instances of intimidation, as well as completin...

Rumination is a process of uncontrolled, narrowly focused negative thinking that is often self-referential, and that is a hallmark of depression. Despite its importance, little is known about its cognitive mechanisms. Rumination can be thought of as a specific, constrained form of mind-wandering. Here, we introduce a cognitive model of rumination that we developed on the basis of our existing m...

BACKGROUND About 20% of major depressive episodes become chronic and medication-refractory and also appear to be less responsive to standard cognitive-behavioural therapy (CBT). AIMS To test whether CBT developed from behavioural activation principles that explicitly and exclusively targets depressive rumination enhances treatment as usual (TAU) in reducing residual depression. METHOD Forty...

Co-ruminating, or excessively discussing problems, with friends is proposed to have adjustment tradeoffs. Co-rumination is hypothesized to contribute both to positive friendship adjustment and to problematic emotional adjustment. Previous single-assessment research was consistent with this hypothesis, but whether co-rumination is an antecedent of adjustment changes was unknown. A 6-month longit...
