On Assessing Individual Differences in Rumination on Sadness

The Rumination on Sadness Scale (RSS), an individual-difference measure of rumination on sadness, was developed as an alternative to the Ruminative Responses scale of the Response Styles Questionnaire (RRRSQ; Nolen-Hoeksema & Morrow, 1991). Research has shown the RRRSQ to consist of multiple, not highly intercorrelated factors; only 1 factor explicitly addresses rumination. In Study 1, a 1-factor solution to a principal components analysis was shown to hold for responses to the RSS. The RSS was also shown to be reliable. In Study 2, convergent and discriminant validity of the RSS were assessed. In Study 3, individuals with high RSS scores exhibited more distress regarding current concerns with the introduction of a delay period (to allow them to ruminate) after a sad mood induction.     

The regulation effects of anger rumination on different foci of anger

Previous studies have shown that anger rumination plays a critical role in increasing anger. The present study examined whether these effects were different with respect to different foci of anger. In Study 1, 96 participants were asked to ruminate about their shame-related or shame-unrelated anger experiences either in an analytical or an experiential way after recalling an autobiographical anger memory. In Study 2, either shame-related or shame-unrelated anger was evoked in participants (n = 176) by an accomplice, and then the participants were instructed to ruminate in one of the following ways: self-distanced analytical, self-distanced experiential, self-immersed analytical, and self-immersed experiential rumination. Study 1 showed significant interaction effects between the foci of anger and the mode of processing. Study 2 showed significant three-way interaction effects among the foci of anger, the mode of processing and the vantage perspective of rumination. Specifically, the results indicated that self-immersed analytical rumination was more useful than the other types of rumination in reducing shame-unrelated anger, while no difference was found regarding shame-related anger. These findings indicated that the effects of anger rumination are different regarding the foci of anger.     

The development of a trait measure of ruminative thought

A 9-item questionnaire was designed to measure rumination. This questionnaire measures three distinct facets of rumination: emotionality, motivation, and distraction. Together, these factors measure the extent to which people engage in thoughts regarding their progress toward their goals. In Study 1, an exploratory factor analysis of an initial 28 items was used to reveal the underlying structure of the rumination construct. In Study 2, a confirmatory factor analysis revealed support for the hypothesized factor structure proposed by Study 1. Following the suggestions of PROC CALIS (SAS) for model modification, an acceptable model was found that retained 9 items (3 on each factor). Studies 3 and 4 demonstrate the predictive validity of the rumination inventory. Study 3 provides evidence of a correlation between distraction by ruminative thoughts and low scores on a statistics examination. Study 4 shows a negative correlation between distraction by ruminative thoughts and time taken to learn to solve a geometric puzzle.     

Understanding impulsive aggression: Angry rumination and reduced self-control capacity are mechanisms underlying the provocation-aggression relationship

Interpersonal provocation is a common and robust antecedent to aggression. Four studies identified angry rumination and reduced self-control as mechanisms underlying the provocation-aggression relationship. Following provocation, participants demonstrated decreased self-control on an unpleasant task relative to a control condition (Study 1). When provoked, rumination reduced self-control and increased aggression. This effect was mediated by reduced self-control capacity (Study 2). State rumination following provocation, but not anger per se, mediated the effect of trait rumination on aggression (Study 3). Bolstering self-regulatory resources by consuming a glucose beverage improved performance on a measure of inhibitory control following rumination (Study 4). These findings suggest that rumination following an anger-inducing provocation reduces self-control and increases aggression. Bolstering self-regulatory resources may reduce this adverse effect.     

Getting Out of Rumination: Comparison of Three Brief Interventions in a Sample of Youth

Rumination, passively and repetitively dwelling on and questioning negative feelings in response to distress, is a risk factor for the development of psychopathology, especially depression. The ruminative process is difficult to stop once it has begun. The present studies focused on strategies that may help youth disengage from ruminative states. In Study 1, we validated a technique for inducing distress and measuring state rumination. Twenty-six participants (mean age?=?12.21; 62?% girls) underwent a negative mood induction followed by either a rumination or distraction induction. In Study 2, we examined the utility of three different brief interventions for stopping the ruminative process. One hundred-two youth (mean age?=?11.51; 64?% girls) underwent a negative mood induction followed by a rumination induction. Following this, participants were randomly assigned to one of three conditions designed to help them out of the ruminative state (distraction, problem-solving, or mindfulness). In Study 1, participants in the rumination condition reported significantly higher levels of state rumination compared to those in the distraction condition. In Study 2, both distraction and mindfulness helped reduced state rumination compared to problem-solving. Taken together, these data suggest that even a brief period of distraction or mindfulness is helpful in getting youth out of a ruminative state. Clinical implications might include the potential use of mobile device applications to help alleviate rumination.     

Forgiveness in Javanese collective culture: The relationship between rumination,harmonious value,decisional forgiveness and emotional forgiveness

Forgiveness in Javanese collective culture is examined by considering harmonious value (HV) a subjective value on maintaining social harmony and rumination. In Study 1, we conducted an exploratory sequential mixed‐method study to develop a scale measuring HV. In‐depth interviews with eight Javanese adolescents revealed three major domains of HV (Study 1a). In a second quantitative study (Study 1b), we developed items and assessed 347 Javanese adolescents in Yogyakarta, Indonesia. Principal component analysis and confirmatory factor analysis supported three factors: cooperation during conflict, forbearing and resolving conflict. After confirming that the translated scales had acceptable reliability, we conducted Study 2 with 424 Javanese adolescents from both urban and village settings. Using hierarchical multiple regression, we found that HV accounted for a variance in decisional forgiveness above and beyond rumination. In addition, decisional forgiveness also accounted for variance in emotional forgiveness above and beyond rumination. In fact, HV accounted for variance in emotional forgiveness above and beyond both rumination and decisional forgiveness together. This revealed the importance of valuing social harmony in this collectivistic culture. Moreover, decisional forgiveness was also important in predicting the Javanese collectivists’ emotional forgiveness.     

The relation between rumination and temporal features of emotion intensity

Intensity profiles of emotional experience over time have been found to differ primarily in explosiveness (i.e. whether the profile has a steep vs. a gentle start) and accumulation (i.e. whether intensity increases over time vs. goes back to baseline). However, the determinants of these temporal features remain poorly understood. In two studies, we examined whether emotion regulation strategies are predictive of the degree of explosiveness and accumulation of negative emotional episodes. Participants were asked to draw profiles reflecting changes in the intensity of emotions elicited either by negative social feedback in the lab (Study 1) or by negative events in daily life (Study 2). In addition, trait (Study 1 & 2), and state (Study 2) usage of a set of emotion regulation strategies was assessed. Multilevel analyses revealed that trait rumination (especially the brooding component) was positively associated with emotion accumulation (Study 1 & 2). State rumination was also positively associated with emotion accumulation and, to a lesser extent, with emotion explosiveness (Study 2). These results provide support for emotion regulation theories, which hypothesise that rumination is a central mechanism underlying the maintenance of negative emotions.     

Imagery and verbal thought during rumination and distraction: Does imagery amplify affective response?

Rumination has long been considered a verbal thought process, though emerging evidence suggests that some individuals dwell on maladaptive imagery. This series of studies evaluated imagery and verbal thought during experimentally induced rumination and distraction. In Study 1, imagery and verbal thought during rumination resulted in similar increases in negative affect. Greater imagery during distraction, on the other hand, was associated with greater decreases in negative affect while verbal thought was not related to affect change. Given that greater verbal thought was reported in the rumination condition and greater imagery was reported in the distraction condition, Study 2 evaluated whether the rumination/distraction induction was confounded by concurrent induction of imagery or verbal thought. The rumination prompts induced both rumination and verbal thought and the distraction prompts induced both distraction and imagery. Using a revised induction, Study 3 tested whether imagery and verbal thought during rumination and distraction impacted affective response. Rumination maintained negative affect and distraction relieved negative affect, regardless of the degree to which imagery or verbal thought was experienced. This paper provides evidence that imagery-based rumination is just as impairing as verbally-based rumination and highlights imagery-based distraction as a potentially effective alternative to rumination.     

The longitudinal relationship between angry rumination and reactive–proactive aggression and the moderation effect of consideration of future consequences-immediate

The idea that influential factors for two subtypes of aggression (reactive and proactive aggression) should be different is popular, but the common influential factors have not been examined. Such an examination could help understand the influential factors of aggression from the perspective of multiple motivations affecting the development of aggressive motivations over time. The present study argued that angry rumination would be a common influential factor for both reactive and proactive aggression. In addition, consideration of future consequences (CFC) may moderate the longitudinal effect of angry rumination on proactive aggression. Two studies were conducted to test these hypotheses. In Study 1, a cross-lagged analysis with a 6-month interval was employed. A total of 505 undergraduate students (46% males) completed the questionnaires twice. Results indicated that after a 6-month period, angry rumination predicted reactive aggression but not proactive aggression. Furthermore, reactive aggression predicted angry rumination over time. In Study 2, a moderation analysis was performed with another 437 participants (130 males). The results partly supported our hypotheses, indicating that CFC-immediate (CFC-I) moderated the longitudinal effect of angry rumination on proactive aggression. The present results extended prior research regarding the predictors of proactive and reactive aggression and may contribute to a greater understanding of the development of aggressive motivation. In addition, our research suggested that high CFC-I may be an important factor for the motivation change from reactive aggression to proactive aggression.     

Rumination, negative cognition, and their interactive effects on depressed mood

Response styles theory posits that rumination represents a trait vulnerability to depression. Recent evidence has suggested that rumination predicts changes in depression more strongly among individuals with high levels of negative cognition. Three studies evaluated this model of interactive vulnerabilities. Study 1 provided empirical support for the distinction between rumination and negative cognitive content. The next 2 studies investigated the interactive model in the laboratory. Study 2 randomly assigned participants to either ruminate or distract following a sad mood induction. This study found that rumination was more strongly associated with dysphoria among individuals who report high levels of negative cognition. Similarly, Study 3 found that rumination and negative cognition interact to predict changes in dysphoria across a no-task delay period following a sad mood induction. These studies provide support for an interactive model in which rumination amplifies the deleterious effects of negative cognition.     

Do people ruminate because they haven’t digested their goals? The relations of rumination and reflection to goal internalization and ambivalence

In three studies it was investigated whether rumination was related to less internalized self-regulation and goals and whether reflection was related to more internalized self-regulation and goals. In all studies students completed questionnaires measuring rumination, reflection, and internalization of self-regulation and goals. In Study 1, rumination was related to less internalized self-regulation, whereas reflection was related to more internalized self-regulation. In Study 2, rumination was related to less internalized self-regulation and goals as well as to more avoidance- and extrinsic content of goals. Reflection was related to more internalized self-regulation and goals as well as to less avoidance content of goals. In Study 3, goal-specific rumination was related to less internalized goals and goal-specific reflection was related to more internalized goals. Collectively, the studies suggest that internalization of self-regulation and goals is critical for distinguishing between unconstructive and constructive self-focused repetitive thoughts.     

All in the mind's eye? Anger rumination and reappraisal

Research on rumination has demonstrated that compared with distraction, rumination intensifies and prolongs negative emotion. However, rumination and distraction differ both in what one thinks about and how one thinks about it. Do the negative outcomes of rumination result from how people think about negative events or simply that they think about them at all? To address this question, participants in 2 studies recalled a recent anger-provoking event and then thought about it in 1 of 2 ways: by ruminating or by reappraising. The authors examined the impact of these strategies on subsequent ratings of anger experience (Study 1) as well as on perseverative thinking and physiological responding over time (Study 2). Relative to reappraisal, rumination led to greater anger experience, more cognitive perseveration, and greater sympathetic nervous system activation. These findings provide compelling new evidence that how one thinks about an emotional event can shape the emotional response one has.     

When love is not blind: rumination impairs implicit affect regulation in response to romantic relationship threat

The present research examined how rumination influences implicit affect regulation in response to romantic relationship threat. In three studies, the disposition to ruminate impaired the ability to maintain positive feelings about the romantic partner in the face of explicit or implicit reminders of relationship threatening events. In Study 1, a high disposition to ruminate was correlated with impaired down-regulation of negative feelings toward the partner in response to a hurtful relationship incident. Two follow-up studies manipulated relationship threat explicitly through an experiential recall procedure (Study 2) or implicitly through a subliminal evaluative-conditioning procedure (Study 3). In both studies only individuals with low disposition to ruminate were able to ward off negative feelings and maintain positive feelings toward the partner. These findings illuminate the role of implicit affect regulation in the context of relationship threat-and how it is inextricably connected with the processes underlying rumination.

The effects of worry and rumination on affect states and cognitive activity

The effects of worry and rumination on affective states and mentation type were examined in an unselected undergraduate sample in Study 1 and in a sample of individuals with high trait worry and rumination, high rumination, and low worry/rumination in Study 2. Participants engaged in worry and rumination inductions, counterbalanced in order across participants to assess main and interactive effects of these types of negative thinking. During mentation periods, the thought vs. imaginal nature and the temporal orientation of mentations were assessed 5 times. Following mentation periods, negative and positive affect, relaxation, anxiety, and depression were assessed. Both worry and rumination produced increases in negative affect and decreases in positive affect. Worry tended to generate greater anxiety, and rumination tended to generate greater depression. Interactive effects were also found indicating that worry may lessen the anxiety experienced during subsequent rumination. Moreover, worry lessened the depressing effects of rumination. Worry was associated with significantly greater thought than imagery, compared to rumination. Rumination involved a progression from mentation about the past to mentation about the future over time. Implications for understanding the generation of negative affect and comorbid anxiety and depression are discussed.     

Emotion Differentiation as a Protective Factor Against the Behavioral Consequences of Rumination: A Conceptual Replication and Extension in the Context of Social Anxiety

Rumination is thought to play a central role in affective disorders such as social anxiety disorder (SAD). Past research indicates that rumination tends to exacerbate negative emotions and increase the risk of engaging in maladaptive coping behaviors (e.g., avoiding social activities). However, little is known on how to effectively protect against the negative outcomes of rumination. Previously, Zaki, Coifman, Rafaeli, Berenson, and Downey (2013) found that negative emotion differentiation (NED) protected against rumination and nonsuicidal self-injury in borderline personality disorder. Nevertheless, it is unclear whether this protective effect would extend to other populations and behaviors. Therefore, the present investigation sought to replicate and extend Zaki et al.’s (2013) findings in the context of SAD. In two studies, we examined if NED would moderate the positive association between rumination and frequency of social avoidance. Study 1 involved 29 individuals who met criteria for SAD with or without co-occurring major depressive episode, while Study 2 involved a nonclinical sample of 190 college students. All participants completed a measure of rumination and an experience-sampling diary which provided indices of NED and social avoidance. The results from both studies were unanimous: NED significantly moderated the relationship between rumination and social avoidance such that the positive association between rumination and social avoidance was significant for low but not moderate to high NED. Overall, the findings provide a conceptual replication of Zaki et al. (2013) and further evidence for the protective effects of NED against the maladaptive behavioral consequences of rumination across populations.     

Why ruminators are poor problem solvers: clues from the phenomenology of dysphoric rumination

The phenomenology of dysphoric rumination and its consequences for problem solving were explored in 3 studies. In Study 1, self-focused rumination, compared with distraction, led dysphoric participants to rate their own biggest problems as severe and unsolvable and to report a reduced likelihood of actually implementing their solutions. Clues into the mechanisms behind these findings were explored in Study 2. The results showed that dysphoric ruminative thought is characterized by a focus on personal problems combined with a negative tone, self-criticism, and self-blame for problems as well as reduced self-confidence, optimism, and perceived control. Finally, Study 3 revealed a direct relationship between the negatively biased content of ruminative thoughts and reduced willingness to solve one's problems. Implications of these findings for the consequences of self-focused rumination are discussed.     

Getting stuck in depression: The roles of rumination and emotional inertia

Like many other mental disorders, depression is characterised by psychological inflexibility. Two instances of such inflexibility are rumination: repetitive cognitions focusing on the causes and consequences of depressive symptoms; and emotional inertia: the tendency for affective states to be resistant to change. In two studies, we tested the predictions that: (1) rumination and emotional inertia are related; and (2) both independently contribute to depressive symptoms. We examined emotional inertia of subjective affective experiences in daily life among a sample of non-clinical undergraduates (Study 1), and of affective behaviours during a family interaction task in a sample of clinically depressed and non-depressed adolescents (Study 2), and related it to self-reported rumination and depression severity. In both studies, rumination (particularly the brooding facet) and emotional inertia (particularly of sad/dysphoric affect) were positively associated, and both independently predicted depression severity. These findings demonstrate the importance of studying both cognitive and affective inflexibility in depression.     

Self-esteem and persistence in the face of failure

In 2 studies, the authors examined self-esteem, persistence, and rumination in the face of failure. Study 1 manipulated degree of failure and availability of goal alternatives. When an alternative was available, high self-esteem (HSE) participants persisted more than low self-esteem (LSE) participants after a single failure, but less after repeated failure. When no alternative was available, no self-esteem differences in persistence emerged. LSE participants ruminated more than HSE participants. Study 2 examined persistence and rumination for 10 personal goals across an academic year. HSE participants were better calibrated (higher within-subject correlations between perceived progress and persistence across goals), had higher overall levels of persistence, higher grade point averages, and lower levels of rumination than LSE participants. Although traditional views that emphasize the tenacious persistence of HSE individuals need revision, HSE people appear more effective in self-regulating goal-directed behavior.     

Can't quite commit: rumination and uncertainty

Why do some individuals persist in self-destructive rumination? Two studies investigated the relation between a ruminative response style and the reluctance to initiate instrumental behavior. In Study 1, ruminators were compared to nonruminators regarding their evaluation of a self-generated plan to revise their university housing system and, in Study 2, concerning their plan to redesign the undergraduate curriculum. In both studies, on relevant composite measures, ruminators expressed less satisfaction and confidence with regard to their plans than did nonruminators. They were also less likely to commit to the plans they generated. The findings suggest that in addition to its documented detrimental effects on thinking and problem solving, self-focused rumination may inhibit instrumental behavior by increasing uncertainty, resulting in further rumination and behavioral paralysis.
