There is growing evidence that brooding rumination plays a key role in the intergenerational transmission of major depressive disorder (MDD) and may be an endophenotype for depression risk. However, less is known about the mechanisms underlying this role. Therefore, the goal of the current study was to examine levels of brooding in children of mothers with a history of MDD (n = 129) compared to children of never depressed mothers (n = 126) and to determine whether the variation in a gene known to influence hypothalamic-pituitary-adrenal axis functioning-corticotropin-releasing hormone receptor 1 (CRHR1) -would moderate the link between maternal MDD and children's levels of brooding. We predicted children of mothers with a history of MDD would exhibit higher levels of brooding than children of mothers with no lifetime depression history but that this link would be stronger among children carrying no copies of the protective CRHR1 TAT haplotype. Our results supported these hypotheses and suggest that the development of brooding among children of depressed mothers, particularly children without the protective CRHR1 haplotype, may serve as an important mechanism of risk for the intergenerational transmission of depression.
Transmission of parental neuroticism to offspring's depression: The mediating role of rumination
Personality and Mental Health, 2014
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-offspring dyads. Parents were assessed for depressive symptoms and neuroticism; adult offspring were assessed for depressive symptoms and rumination. Structural equation modelling was used to examine the effects of parental depressive symptoms and parental neuroticism on adult offspring's depression, and to determine whether offspring's rumination mediated this relationship. Results provided evidence that offspring's rumination fully mediated the relationship between parental neuroticism and offspring's depressive symptoms. Parental depressive symptoms and neuroticism may contribute a genetic predisposition for depressive symptoms in offspring, but it also may promote an environment in which maladaptive cognitive processes, such as rumination, are learned. Given the role that rumination plays in mediating the association between neuroticism and depressive symptoms-targeting rumination in the treatment of high risk individuals would be important in reducing onset of depressive disorders.

Specificity of brooding rumination as a cognitive vulnerability for anxiety and depression was examined using the tripartite theory as a framework. The three factors of the tripartite theory (negative affect, positive affect, and physiological hyperarousal) were included in the same structural equation model (latent growth curves) to test three competing hypotheses: brooding rumination as a depression-specific vulnerability (i.e., brooding uniquely predicts shared negative affect + specific positive affect), anxiety-specific vulnerability (i.e., brooding predicts shared negative affect + specific physiological hyperarousal), or shared risk vulnerability (i.e., brooding predicts negative affect, the shared tripartite component common to both anxiety and depression). Data from children in 2nd through 7th grades (N = 303) were collected in three waves over two years. Results revealed brooding to be uniquely associated with initial levels of negative affect and physiological hyperarousal, thus providing support for the anxiety-specific vulnerability. Results from the multigroup analysis confirmed that the relationship among these variables did not differ across sex. Longitudinal associations between brooding and the tripartite factors are also discussed. Identifying cognitive vulnerabilities that increase children's risk for the development of psychopathology in adolescence or adulthood has the potential to inform etiological theories and lead to the development of effective treatment and preventive interventions. Rumination, the tendency to perseverate about the symptoms, causes, and consequences of negative mood, is a cognitive vulnerability that has been the focus of considerable research and one that has been consistently linked to concurrent and future levels of children's
Genetic and environmental influences on rumination and its covariation with depression
Cognition & Emotion, 2014
This study examined the extent to which rumination and depression share genetic and environmental influences in a community sample of adult twins (N=663). Twins completed multiple rumination questionnaires, a depressive symptoms questionnaire and a diagnostic interview. Rumination was moderately heritable (h2=.37-.41 for the latent variable) and substantially influenced by nonshared environmental factors, and these results were consistent across different measures. Nonshared environmental influences on rumination were larger for women than men. Depressive symptoms and diagnosis were influenced by genetic and nonshared environmental factors (h2=.30-.45). The genetic correlations between rumination and depression were moderate to large (rA=.40-.82), suggesting that a substantial proportion of the genetic influences on rumination overlap with those on depression. Results were similar when examining self-reported depressive symptoms and interview-based diagnosis of major depressive disorder. These results highlight the importance of rumination in the integration of cognitive and genetic models of depression risk.
Depressive Rumination and Co-Morbidity: Evidence for Brooding as a Transdiagnostic Process
Journal of Rational-Emotive & Cognitive-Behavior Therapy, 2009
A sample of 116 patients with unipolar mood disorders referred to a specialist research clinic were assessed to investigate (a) whether rumination is a transdiagnostic process that is related to co-morbid Axis I and II symptoms and diagnosis in depressed patients; (b) whether common findings in the depressive rumination literature could be replicated in a recurrent depressed sample. Consistent with the transdiagnostic hypothesis, rumination was positively associated with both depression and anxiety, brooding was related to co-morbid obsessive-compulsive disorder and generalized anxiety disorder, and rumination was associated with traits associated with borderline personality disorder, most notably self-report of unstable relationships and inconsistent sense of self. As predicted, rumination was equivalent in currently depressed and formerly depressed patients, suggesting that rumination is not simply dependent on mood state or clinical status. As predicted, the brooding subtype most strongly correlated with depressed and anxious symptoms, consistent with previous observations that brooding is the more maladaptive form of rumination. As predicted, rumination was associated with reports of sexual abuse. Inconsistent with previous findings, there was no gender difference in rumination.
Genetic and Environmental Influences on Rumination, Distraction, and Depressed Mood in Adolescence
Clinical psychological science : a journal of the Association for Psychological Science, 2013
Rumination is an established cognitive vulnerability for depression. Despite substantial work on the environmental origins of rumination, the heritability of rumination has not been examined and it is not known whether rumination accounts for some of the genetic vulnerability associated with depression. 756 adolescent twins ages 12-14 years completed the Response Styles Questionnaire and multiple measures of depressive symptoms. Brooding correlated positively and distraction correlated negatively with concurrent depressive symptoms. Estimated heritabilites were 54% for depression, 21% for brooding, 37% for reflection, and 30% for distraction. Bivariate genetic analyses suggested that (1) individual differences in distraction share both genetic and environmental sources of variation with depression; and (2) although the heritable influences on brooding are small, these heritable influences account for the majority of the relationship between brooding and depression (h(2) = .62).

The present study investigated the validity of the two-factor solution of items selected from the Rumination Scale of the Response Style Questionnaire proposed by Treynor, . In the first part of this study we used samples of currently depressed (MDD), formerly depressed (FD), socially anxious (SP), and healthy control participants to examine whether the brooding and reflective pondering components differentiate participants with an anxiety disorder from participants with depression. In the second part of this study we examined whether these components of rumination were differentially related to cognitive biases in depression. Overall, the MDD group exhibited higher brooding scores than did all other groups; SP and FD groups did not differ from each other but obtained higher brooding scores than did the control participants. Only the MDD and the control groups differed on the reflective pondering factor. Importantly, brooding and reflective pondering were differentially related to cognitive biases. Specifically, the correlation between brooding/reflective pondering and memory bias was not significant when depressive symptoms were partialed out. The correlation between brooding and attentional bias for sad faces, however, remained significant even when current depressive symptoms were taken into account. In sum, our results support the formulation that rumination is composed of an adaptive reflective pondering factor and a maladaptive brooding factor.
Rumination in adolescents at risk for depression
Journal of Affective Disorders, 2006
Background: Identifying high-risk adolescents and understanding first onset of depression in adolescence are important steps in reducing depression morbidity. There is compelling evidence that the personality dimension neuroticism is a risk factor for depression, but the vulnerability mechanism is not yet understood. This study examined the association between a hypothesized psychological vulnerability factor (rumination) and depression in adolescents. Methods: A behavioural high-risk design differentiated a sample of 326 adolescents (aged 14-18) as either at normal or high risk for depression (operationalized as scores on a measure of neuroticism). Results: Adolescents at risk for depression reported more rumination than adolescents not at risk. We hypothesized that the well established relationship between neuroticism and depression would be mediated by rumination in cross-sectional analyses, and our findings suggest that rumination partially mediated this relationship. Conclusions: The findings tentatively suggest that neuroticism acts as a risk factor for adolescent onset depression through increased tendency towards brooding rumination (i.e. moody self-evaluative dwelling) in response to depressed mood. Prospective and experimental research examining this mechanism is required.
