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-...

Rumination in response to stress (stress-reactive rumination) has been linked to higher levels of depressive symptoms in adolescents. However, no work to date has examined the neural mechanisms connecting stress-reactive rumination and adolescent depressive symptoms. The present work attempted to bridge this gap through an fMRI study of 41 adolescent girls (Mage=15.42, SD=0.33) - a population i...

The concept of gang aggression oftentimes elicits images of brutal inter-gang violence. In reality, gang-related aggression can vary widely, can have various motivations and causal factors, and includes interpersonal as well as intergroup aggression. This study examined the tendency of U.K. youth to engage in displaced aggression (aggression aimed at undeserving targets) and examined the relati...

BACKGROUND Cognitive behavioural therapy is an effective treatment for depression. However, one third of the patients do not respond satisfactorily, and relapse rates of around 30 % within the first post-treatment year were reported in a recent meta-analysis. In total, 30-50 % of remitted patients present with residual symptoms by the end of treatment. A common residual symptom is rumination, a...

BACKGROUND AND OBJECTIVES Rumination, a maladaptive cognitive style of responding to negative mood, is thought to be maintained by a variety of cognitive biases. However, it is unknown whether rumination is characterized by interpretation biases. METHODS Two experiments examined the link between rumination and interpretation biases, revealed in lexical-decision tasks (LDT). A homograph with b...

BACKGROUND Rumination syndrome, characterised by the effortless, often repetitive, regurgitation of recently ingested food into the mouth, was originally described in children and in the developmentally disabled. It is now well-recognised that rumination syndrome occurs in patients of all ages and cognitive abilities. AIM To review a scholarly review on our current understanding of the rumina...

Failure of the hypothalamus-pituitary-adrenal (HPA) axis to habituate to repeated stress exposure is related with adverse health outcomes, but our knowledge of predictors of non-habituation is limited. Rumination, defined as repetitive and unwanted past-centered negative thinking, is related with exaggerated HPA axis stress responses and poor health outcomes. The aim of this study was to test w...

Rumination is a cognitive process that involves repetitively focusing on the causes, situational factors and consequences of one's negative emotion, and it is a potent risk factor for depression. Parental depression and neuroticism may exert an influence on offspring's development of rumination, which may increase offspring's risk for depression. The current study included 375 biological parent...
