INTRODUCTION Rumination is a multidimensional trait which is a proven risk factor in the vulnerability to depression. The aim to identify the main risk genes for depression in addition to the gene-environment interactions pointed to the importance of intermediate phenotypes, like rumination, to improve our understanding of the biological mechanisms of depression. Catechol-O-Methyltransferase (C...

BACKGROUND Rumination is an important cognitive risk factor for onset and relapse of depression. However, no studies have employed a dimensional approach in investigating the neural correlates of rumination and the relationship with depression. METHOD Non-clinical healthy subjects (n = 306), who completed the classical rumination and depression scales, were studied using voxel-based morphomet...

BACKGROUND AND OBJECTIVES The current study tested the resource allocation hypothesis, examining whether baseline rumination or depressive symptom levels prospectively predicted deficits in executive functioning in an adolescent sample. The alternative to this hypothesis was also evaluated by testing whether lower initial levels of executive functioning predicted increases in rumination or depr...

BACKGROUND A ruminative style of responding to low mood is associated with subsequent high depressive symptoms and depressive disorder in children, adolescents and adults. Scores on self-report rumination scales correlate strongly with scores on anxiety and depression symptom scales. This may confound any associations between rumination and subsequent depression. METHODS Our sample comprised ...

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 ...
