Multidimensional Perfectionism and Ruminative Brooding in Current Dysphoria,Anxiety, Worry,and Anger

The current study examined links between dimensions of perfectionism, ruminative and distractive coping, and multiple measures of current distress (dysphoria, anxiety, worry, and anger) in 205 university students. A main goal was to test the hypothesis that perfectionism is related to a new measure of the critical maladaptive component of rumination (i.e., ruminative brooding) that is not confounded with symptoms and confirm that both constructs function as non-specific vulnerabilities for emotional distress. Our study revealed numerous significant findings, including: (1) socially prescribed perfectionism (SPP) was the dimension most strongly related to brooding in response to depression and anxiety; (2) SPP, self-oriented perfectionism (SOP), and brooding predicted various indices of distress; (3) SOP predicted anxiety and worry in women, and it predicted dysphoria and anger in men; (4) despite the strong associations between ruminative brooding and distress, perfectionism still accounted for unique variance in distress, and vice-versa. Implications for the issue of the adaptiveness versus maladaptiveness of perfectionism and for counseling perfectionists who fall into the “brooding trap” are discussed.

Submissive interpersonal style mediates the effect of brooding on future depressive symptoms

Theoretical models and empirical evidence suggest that brooding, the maladaptive sub-component of depressive rumination, is associated with a sub-set of depressogenic interpersonal difficulties characterised by submissive interpersonal behaviours and rejection sensitivity. This study tested whether these cognitive and interpersonal vulnerability factors independently predicted future depression and investigated their interdependence in predicting depression. A heterogeneous adult sample completed self-report measures assessing depressive symptoms, brooding, reflection, rejection sensitivity and maladaptive interpersonal behaviours, at baseline and six months later. When examined separately, brooding and an interpersonal component reflecting submissive, (overly-accommodating, non-assertive, and self-sacrificing) interpersonal behaviours each prospectively predicted increased depressive symptoms six months later, after controlling for baseline depressive symptoms and gender. When examined together, the submissive interpersonal style but not brooding predicted depression, indicating that this maladaptive interpersonal style may mediate the effect of brooding on future depression. Thus, the effects of brooding on depression may in part depend on its association with an interpersonal style characterised by submissiveness.     

Psychosocial correlates of depressive rumination

The study examined the relationship between brooding, the maladaptive sub-component of depressive rumination, an important cognitive mechanism implicated in the aetiology of depression, and a range of depressogenic psychosocial factors, including insecure attachment styles and maladaptive interpersonal behaviours. It was hypothesised that brooding (but not the more adaptive reflection component) is associated with an attachment pattern characterised by fear of rejection, and an interpersonal style characterised by submissiveness. Currently depressed (n = 29), previously depressed (n = 42) and never-depressed (n = 32) adults completed self-report measures assessing depressive symptoms, rumination (brooding and reflection), attachment orientation and maladaptive interpersonal behaviours. The study hypotheses were partially supported: After controlling for gender and depressive symptoms, brooding was significantly associated with one indicator of underlying rejection concerns (rejection sensitivity, p = .05), but was not associated with another indicator of underlying rejection concerns (anxious attachment style) or with avoidant attachment style. After controlling for depressive symptoms, brooding was uniquely associated with the submissive interpersonal style (p < .01). Brooding was not correlated with needy or cold interpersonal styles after controlling for depressive symptoms.     

Over and over again: Rumination, reflection, and promotion goal failure and their interactive effects on depressive symptoms

Research indicates that examining failure experiences using an immersed processing style versus a non-immersed, self-distanced open style influences cognitions about the self, motivation, and subsequent depressive symptoms. However, the effect of processing goal failure experiences using these different processing styles have not been adequately incorporated into existing self-regulation theories of depression. In a cross-sectional study, we examined the interactive effects of rumination (versus reflection) and failure to attain promotion goals on depressive symptoms. As predicted, greater levels of promotion goal failure were associated with having more depressive symptoms for individuals who engage in moderate to high levels of rumination. In contrast, among individuals who engage in high levels of self-reflection, promotion goal failure was not associated with an appreciable increase in depressive symptoms. We discuss the implications of these results for self-regulatory theories of depression and treatments for depression.     

Rumination and worrying as possible mediators in the relation between neuroticism and symptoms of depression and anxiety in clinically depressed individuals

Rumination and worrying are considered possible mediating variables that may explain the relation between neuroticism and symptoms of depression and anxiety. The current study sought to examine the mediational effects of rumination and worry in the relationships between neuroticism and symptoms of depression and anxiety in a sample of clinically depressed individuals (N = 198). All patients completed a battery of questionnaires including measures of neuroticism, rumination, worrying, depression, and anxiety. Results showed that in subsequent analyses, rumination and worrying both mediated the relation between neuroticism and depression and anxiety. When rumination and worrying were simultaneously entered in the mediation analysis, only rumination was found to mediate the relation between neuroticism and symptoms of anxiety and depression. Two components of rumination (i.e., brooding and reflection) were also analyzed in the mediational analysis. Both reflection and brooding were significant mediators with respect to depressive symptoms, whereas brooding was the only significant mediator in relation to anxiety symptoms. The results are discussed in the light of current theories, previous research, and recent treatment developments. Clinical implications and suggestions for future research are provided.     

Gender differences in rumination: A meta-analysis

Starting in adolescence and continuing through adulthood, women are twice as likely as men to experience depression. According to the response styles theory (RST), gender differences in depression result, in part, from women’s tendency to ruminate more than men. A meta-analysis was performed to evaluate gender differences in rumination in adults (k = 59; N = 14,321); additionally, an analysis of subtypes of rumination – brooding and reflection – was conducted (k = 23). Fixed effects analyses indicated that women scored higher than men in rumination (d = .24, p < .01, SEd = .02), brooding (d = .19, p < .01, SEd = .03) and reflection (d = .17, p < .01, SEd = .03); there was no evidence of heterogeneity or publication bias across studies for these effect sizes. Although statistically significant, the effect sizes for gender differences in rumination were small in magnitude. Results are discussed with respect to the RST and gender differences in depression.     

Worry and rumination: differential associations with anxious and depressive symptoms and coping behavior

Worry and rumination are closely allied cognitive processes that impact on the experience of anxious and depressive symptoms. Using a prospective design, this study examined overlapping and distinct features of worry and rumination in relation to symptoms and coping behavior in a nonclinical sample of Singaporean college students. Worry and rumination were highly correlated, but they retained distinct components that predicted anxious and depressive symptoms differentially within and across time. Specifically, worry was uniquely associated with anxious and depressive symptoms whereas rumination was uniquely related to depression. In comparison to rumination, worry emerged as the dominant cognitive vulnerability factor that predicted increments in symptoms over time. With regards to coping behavior, low perceived coping effectiveness partially mediated the relation between worry and increases in anxiety and depression. Conversely, rumination uniquely predicted higher disengagement from problems, which resulted in further exacerbation of depressive mood. These results demonstrated not only the distinct features of worry and rumination on coping behavior, but also the different coping pathways by which they differentially impact on subsequent symptoms.     

Rumination as a transdiagnostic factor in depression and anxiety

The high rate of comorbidity among mental disorders has driven a search for factors associated with the development of multiple types of psychopathology, referred to as transdiagnostic factors. Rumination is involved in the etiology and maintenance of major depression, and recent evidence implicates rumination in the development of anxiety. The extent to which rumination is a transdiagnostic factor that accounts for the co-occurrence of symptoms of depression and anxiety, however, has not previously been examined. We investigated whether rumination explained the concurrent and prospective associations between symptoms of depression and anxiety in two longitudinal studies: one of adolescents (N = 1065) and one of adults (N = 1317). Rumination was a full mediator of the concurrent association between symptoms of depression and anxiety in adolescents (z = 6.7, p < .001) and was a partial mediator of this association in adults (z = 5.6, p < .001). In prospective analyses in the adolescent sample, baseline depressive symptoms predicted increases in anxiety, and rumination fully mediated this association (z = 5.26, p < .001). In adults, baseline depression predicted increases in anxiety and baseline anxiety predicted increases in depression; rumination fully mediated both of these associations (z = 2.35, p = .019 and z = 5.10, p < .001, respectively). These findings highlight the importance of targeting rumination in transdiagnostic treatment approaches for emotional disorders.     

Brooding and reflective rumination among suicide attempters: Cognitive vulnerability to suicidal ideation

Previous research suggests that the brooding subtype of rumination is associated with increased suicidal ideation, but findings are inconsistent with respect to reflection, considered to be the more adaptive form of rumination. This study investigated the circumstances under which reflective rumination might be associated with increased suicidal ideation by examining whether a suicide attempt history moderated the relationship between the ruminative subtypes and current suicidal ideation. Thirty-seven young adults who reported a past suicide attempt and fifty-nine young adults without a suicide attempt history completed measures of rumination and depression symptoms in an initial study session. They then completed a measure of suicidal ideation and hopelessness during a second study session. Overall, brooding was associated with higher self-reported suicidal ideation, whereas reflection was not significantly associated with ideation. However, reflection - but not brooding - interacted with suicide attempt history to statistically predict suicidal ideation, even after adjusting for symptoms of depression and hopelessness, whereas brooding no longer predicted ideation after adjusting for these symptoms. These findings qualify earlier suggestions that reflection is a more adaptive form of rumination by indicating that among vulnerable individuals - in particular those with a history of a suicide attempt - a higher degree of reflective rumination is associated with increased suicidal ideation.     

Rumination and attention in major depression

Up until recently, it had been assumed that attentional biases for negative information do not exist in depression. However studies using post-conscious exposure durations have produced contradictory results. The limitations of common attentional tasks, suitability of stimulus materials and differences in stimulus duration times may have contributed to these inconsistencies. We aimed to address many of these issues and examine attentional responses in major depression at two post-conscious exposure times. We also investigated possible roles for rumination and distraction in increasing and lessening attentional biases for negative information. We used a fully controlled experimental design to test the effects of both induced and trait rumination and distraction on attention in patients with major depression and healthy controls. Attention was assessed using the dot-probe task. The findings revealed an attentional bias for negative information in depressed patients only at the longer post-conscious exposure duration. Furthermore although this bias was not influenced by either induced or trait distraction, it was related to trait rumination. Overall, the results showed that depression is associated with a strategic attentional bias towards negative information and that this bias is stronger in individuals who habitually ruminate.     

Self-rumination, self-reflection, and depression: Self-rumination counteracts the adaptive effect of self-reflection

Self-focused attention has adaptive and maladaptive aspects: self-reflection and self-rumination [Trapnell, P. D., & Campbell, J. D. (1999). Private self-consciousness and the Five-Factor Model of personality: distinguishing rumination from reflection. Journal of Personality and Social Psychology, 76, 284-304]. Although reflection is thought to be associated with problem solving and the promotion of mental health, previous researches have shown that reflection does not always have an adaptive effect on depression. Authors have examined the causes behind this inconsistency by modeling the relationships among self-reflection, self-rumination, and depression. One hundred and eleven undergraduates (91 men and 20 women) participated in a two-time point assessment with a 3-week interval. Statistical analysis with structural equation modeling showed that self-reflection significantly predicted self-rumination, whereas self-rumination did not predict self-reflection. With regard to depression, self-reflection was associated with a lower level of depression; self-rumination, with a higher level of depression. The total effect of self-reflection on depression was almost zero. This result indicates that self-reflection per se has an adaptive effect, which is canceled out by the maladaptive effect of self-rumination, because reflectors are likely to ruminate and reflect simultaneously.     

The relationship between rumination, avoidance and depression in a non-clinical sample

Recent commentaries have proposed conceptualizations of rumination in terms of both cognitive and behavioral avoidance. This study examined the relationship between rumination, avoidance and depression using a newly developed self-report measure of avoidance in depression, the Cognitive-Behavioral Avoidance Scale (CBAS) [Ottenbreit, N.D., & Dobson, K.S. (2004). Avoidance and depression: The construction of the cognitive-behavioral avoidance scale. Behaviour Research and Therapy, 42, 293-313]. A non-clinical sample (N=104) of undergraduate students completed self-report measures of depression, anxiety, rumination and avoidance. Rumination, avoidance and depression were all significantly correlated. Rumination and behavioral avoidance remained intercorrelated when anxiety was controlled, confirming an association that is independent of anxiety. By contrast, the relationship between cognitive avoidance and rumination disappeared when anxiety was partialled out. Notably, avoidance predicted unique variance in depression scores, over and above anxiety and rumination. Consistent with the proposal of Ottenbreit and Dobson [Avoidance and depression: The construction of the cognitive-behavioral avoidance scale. Behaviour Research and Therapy, 42, 293-313], our findings support the value of clinicians and psychopathologists giving consideration to avoidance in their conceptualization of depression.     

Rumination and overgeneral autobiographical memory

Two studies investigated the effects of rumination on the retrieval of autobiographical memories in high-depressed and low-depressed individuals. Experiment 1 administered either a rumination or distraction task prior to a cued autobiographical memory task. High-depressed participants recalled more overgeneral memories following rumination relative to distraction, whereas experimental inductions did not influence low-depressed participants. Experiment 2 administered either a positive or negative rumination task prior to a cued autobiographical memory task. Negatively valenced rumination led high-depressed participants to recall more overgeneral memories than positively valenced rumination; this effect was not observed in low-depressed participants. These findings accord with the proposal that rumination is a mediating mechanism in the retrieval of overgeneral memories, and extends this proposal by indicating that negatively valenced ruminative content is particularly instrumental in inducing overgeneral retrieval.     

Why “why” seems better than “how”. Processes underlining repetitive thinking in an Italian non-clinical sample

Given the evidence for the dysfunctional effects of rumination, the fundamental question remains: why depressed patients continue to ruminate over long periods of time? Watkins has shown that unconstructive repetitive thought is focused on “why”, aiming at detecting the personal reasons of negative events. This strategy leads people to find evaluative answers of personal inadequacy or negativity of the world. The research aims at (a) test the hypotheses that why RT is significantly correlated to negative mood, even when controlling for depressive symptoms; (b) test whether non-clinical participants really tend to prefer the “how” RT, when coping with an unexpected negative event of everyday life; this results would suggest that the “how” style is more functional than the “why” style; (c) exploring beliefs that may guide the choice between the “how” or the “why” modes; (d) investigate the influence of a previous choice on the subsequent thinking style. 212 participants have been recruited. We include questionnaires about rumination and depression and 8 vignette describing negative unexpected situations, followed by three tasks. The results confirm the detrimental role of why focused repetitive thinking on mood state and show a significant influence of a “why tendency”.
