Dampening of positive affect prospectively predicts depressive symptoms in non-clinical samples

Past research has convincingly shown that a ruminative response style to negative affect (NA) predicts concurrent and prospective levels of depressive symptoms. Recent findings suggest that how people respond to positive affect (PA) might also be involved in the development of depressive symptoms, although this has heretofore not been tested prospectively. Participants from two non-clinical samples (total N=487) completed measures of depressive symptoms, response styles to NA (negative rumination) and response styles to PA (positive rumination and mood dampening) at two assessments separated by a 3-month (Sample 1) and 5-month period (Sample 2). Results in both samples showed that increased dampening responses to PA predict depressive symptoms at follow-up, even when taking into account baseline depressive symptoms and ruminative responses to NA. The results suggest that (dampening) responses to PA add useful information above and beyond (ruminative) responses to NA in predicting depression symptoms prospectively.

The relationship of negative mood regulation expectancies with rumination and distraction

Individuals high in negative mood regulation expectancies believe that a wide variety of actions has the potential to improve their negative mood. According to response expectancy theory, negative mood regulation expectancies affect mood in a nonvolitional and self-confirming manner. The present study evaluated this claim by assessing the ability of negative mood regulation expectancies to predict current depression after controlling for a variety of volitional coping responses, including rumination, distraction, active coping, and avoidant coping. 105 Introduction to Psychology college students at the University of Connecticut, 47 men and 58 women (M age = 20.3 yr., SD = 1.5), completed measures of each of the latter constructs for course credit. Results were consistent with response expectancy theory: negative mood regulation expectancies predicted current depression above and beyond coping behaviors. In addition, higher negative mood regulation expectancies were associated with greater use of adaptive coping responses. Results of this study further support the notion that effects of negative mood regulation expectancies on mood cannot be fully accounted for by intentional coping behaviors.     

Ruminative Inertia,Emotion Regulation,and Depression: A Daily-Diary Study

Emotional suppression and cognitive reappraisal are emotion regulation strategies that have been linked to the severity of depression. Recent research has shown that greater ruminative inertia (i.e., rumination that is more resistant to change across time) is also associated with higher levels of depressive symptoms in clinical samples. However, it is unknown how tendencies to use suppression or reappraisal might be related to the inertia of rumination from day to day. After completing a baseline assessment of depressive symptoms and trait emotional suppression and cognitive reappraisal use, undergraduates (n = 94) completed daily-diary questionnaires assessing rumination for two weeks. Both higher depressive symptoms and greater tendencies to use suppression predicted stronger ruminative inertia, while tendencies to use reappraisal were unrelated to ruminative inertia. These results suggest that maladaptive emotion regulation strategies may contribute to a pattern of rumination that is more resistant to change over time. They also provide the first evidence that ruminative inertia is positively associated with depressive symptoms in a nonclinical sample.     

Gaze-fixation and pupil dilation in the processing of emotional faces: The role of rumination

Sustained attentional processing of negative information plays a significant role in the development and maintenance of depression. The present study examines the relationships between rumination, a relevant factor in information processing in depression, and the attentional mechanisms activated in individuals with different levels of depression severity when attending to emotional information (i.e., sad, angry and happy faces). Behavioural and physiological indicators of sustained processing were assessed in 126 participants (39 dysphoric and 87 non-dysphoric) using eye-tracking technology. Pupil dilation and total time attending to negative faces were correlated with a global ruminative style in the total sample once depression severity was controlled. Furthermore, in dysphoric participants the brooding component of rumination was specifically associated with the total time attending to sad faces. Finally, bootstrapping analyses showed that the relationships between global rumination and pupil diameter to emotional faces were accounted by total time attending to emotional faces, specifically for participants reporting lower levels of depression severity. The results support the idea that sustained processing of negative information is associated with a higher ruminative style and indicate differential associations between these factors at different levels of depressive symptomatology.     

Responses to Positive Affect in Daily Life: Positive Rumination and Dampening Moderate the Association Between Daily Events and Depressive Symptoms

Depressive rumination has been strongly linked to the development and maintenance of depression; however, less attention has been paid to ruminative processes in response to positive affect, and fewer have examined these processes in daily life. The current study sought to address these gaps by exploring depressive rumination and two forms of responses to positive affect, dampening and positive rumination, under ecologically valid conditions using daily diary methodology. One hundred fifty-seven young adults completed 14-day end-of-day diaries assessing positive affect and depressive symptoms in relation to depressive rumination, responses to positive affect, and daily positive and negative events. Daily depressive rumination predicted stronger associations between negative events and daily depressive symptoms. Higher daily dampening was associated with higher daily depressive symptoms and decreased positive affect and predicted lower associations between daily positive events and improvements in mood (including reduced daily positive affect and increased daily depressive symptoms). Higher daily positive rumination was negatively associated with daily depressive symptoms and interacted with daily positive events such that positive rumination had a greater impact on depressed mood on days when positive experiences were low. Results indicate that both depressive rumination and responses to positive affect play a role in influencing daily mood and depressive symptoms.     

Correlation between maternal stress and children's stress

Mothers (N = 168, M age = 37.0 yr., SD = 4.6) responded to a questionnaire of scales measuring sources of stress and symptoms of stress within themselves, and symptoms of stress in their 5-8-yr.-old children (61 girls, 98 boys; M age = 7.3 yr., SD = 1.0). Scores on all scales intercorrelated significantly, indicating a relationship between maternal stress and stress of the child. Both types of stress also correlated with the frequency of punishment of the child. Both maternal stress and frequency of punishment predicted stress symptoms in the children, maternal stress being a somewhat stronger predictor.     

Acceptability and Preliminary Effects of a Mindfulness Mobile Application for Ruminative Adolescents

Rumination is a transdiagnostic risk factor that appears to be reduced through mindfulness interventions. However, mindfulness mobile apps have not been tested for their effects on rumination, especially among adolescents. Thus, we aimed to test the acceptability and effects of a mindfulness mobile intervention among ruminative adolescents using a within-subjects pretest/posttest design. Participants were 80 adolescents ages 12-15, selected for moderate-to-high rumination (M age = 14.01, SD = .99; 46.2% girls; 86.25% White; 3.75% Hispanic). We asked adolescents to use our mindfulness app 3 times per day for 3 weeks. Participants and parents completed questionnaires at baseline, post-intervention, and 6 and 12 weeks later. Acceptability was assessed by tracking app use and asking adolescents and parents to report on their experiences post-intervention. We assessed repetitive negative thinking (i.e., rumination and worry) and internalizing symptoms via self- and parent-report. The intervention demonstrated acceptability, and there were significant reductions in rumination, worry, anxiety and parent-reported internalizing symptoms post-intervention. Effects on rumination, anxiety and internalizing symptoms persisted throughout the 12-week follow-up with large effect sizes using an intention-to-treat approach. Thus, a brief mindfulness mobile app intervention appeared to be both engaging and helpful in reducing negative repetitive thinking and internalizing symptoms among ruminative adolescents. It will be important to test this intervention in a randomized controlled trial to control for effects of time and attention.     

Cognitive inhibition in depression

Cognitive inhibition is a key mechanism in the regulation of emotion. There is emerging evidence that depression is characterized by deficits in the inhibition of mood-congruent material. These deficits could result in prolonged processing of negative, goal-irrelevant aspects of presented information thereby hindering recovery from negative mood and leading to the sustained negative affect that characterizes depressive episodes. Indeed, it has been suggested that deficits in cognitive inhibition lie at the heart of memory and attention biases in depression, and set the stage for ruminative responses to negative events and negative mood states. A ruminative response style results in a heightened vulnerability to experience episodes of major depression. Recent research has demonstrated that deficient inhibition of negative material is associated with heightened rumination. In this article, we review the depression literature with a focus on studies that investigate cognitive inhibition in depressed participants and in participants who report a history of major depressive episodes. In addition, we summarize neurobiological findings that indicate a strong relation between depression and deficits in inhibition and we take a closer look at the relation of inhibition, rumination and mood regulation.     

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.     

The Mediating Role of Rumination in the Relation Between Quality of Attachment Relations and Depressive Symptoms in Non-Clinical Adolescents

This study examined associations between indices of the quality of attachment relationships of adolescents with parents and peers, rumination, and symptoms of depression. More specifically, a mediation model was investigated in which rumination was hypothesized to mediate the relation between quality of attachment relations and symptoms of depression. A total of 455 high school students completed a battery of questionnaires, including quality of attachment relations, rumination, and depression. Results showed that most indices of quality of attachment relations were significantly associated with rumination and symptoms of depression. When examining the relative contribution of these variables in explaining variance in depression symptoms, trust in parents, communication with peers, and alienation from peers accounted for a significant portion of the variance in depression scores. Finally, the relation between communication with peers and depressive symptoms was fully mediated by rumination, whereas partial mediation was found for the relations between parental trust and depressive symptoms, and between alienation from peers and depressive symptoms. Implications of the findings may be that the treatment of depression in adolescence should consist of both cognitive interventions aimed at targeting ruminative thinking as well as a focus on interpersonal relationships of the adolescent with parents and peers.     

Ruminative and mindful self-focused processing modes and their impact on problem solving in dysphoric individuals

A mindful experiential rather than an analytical ruminative mode of information processing is beneficial in depression. However studies have not taken into account people’s trait mindfulness or trait rumination. This study aimed to examine the effects of state and trait analytical rumination and experiential mindfulness on affect and social problem solving (SPS). Participants filled in the trait mindfulness and trait rumination questionnaires. After mood induction, dysphoric participants with and without a history of depression were assessed for SPS and affect before and after induction of mindful (experiential) or ruminative (analytic) processing modes. Results showed trait mindfulness was negatively correlated with the BDI and trait rumination was positively correlated with the BDI. There was no significant difference between groups after the induced experiential mindful or analytical ruminative processing modes. However, participants who scored high on trait rumination showed significant improvement in SPS after induced mindfulness processing. No such effect was found on trait mindfulness. These findings suggest a useful way to prevent high trait ruminators from developing depressive symptoms or depression. Experiential mindful processing may help reduce the risk of developing depressive symptoms by increasing social problem solving ability in those with low mood and high levels of trait rumination.     

Ruminative Thoughts and Their Relation to Depression and Anxiety1

Although past research has shown a correlation between ruminative response style and depression (Nolen-Hoeksema, 1991), the basic relationships among amount of ruminative thoughts, depression, and anxiety has not been established. Scores from the Beck Depression Inventory-Second Edition (BDI-II; Beck, Steer, & Brown, 1996), the Beck Anxiety Inventory (BAI; Beck & Steer, 1993), and the McIntosh and Martin (1992) Rumination Scale were analyzed for 199 participants. The correlation between rumination and depression was .33, between rumination and anxiety was .32, and between depression and anxiety was .56. The partial correlation between rumination and depression (controlling for anxiety level) was .20, and the partial correlation between rumination and anxiety (controlling for depression level) was .17. The finding that rumination is not unique to depression but is also associated with the specific negative affect of anxiety alone might also suggest new treatments of these two prevalent disorders.     

A Kid-Friendly Tool to Assess Rumination in Children and Early Adolescents: Relationships with Mother Psychopathology and Family Functioning

The early identification of ruminative processes in children and early adolescents is particularly important to prevent the development of a stable ruminative style in later stages of development. The present study first aimed at validating a child-friendly tool, Kid Rumination Interview (KRI), to be used in a sample aged 7–12 years (n?=?100; 50% females). Second, we hypothesized that maternal depression, family functioning and participants’ emotion regulation skills would be associated with children’ levels of rumination. Factor analysis on KRI scores yielded two main factors: personal life-related rumination and school-related rumination. Older and female participants showed higher tendencies to ruminate about school issues compared to their younger and male counterparts. A low-to-moderate correlation emerged between school-related rumination and child/early adolescent’s emotion regulation capacities. Mothers’ depressive rumination and mothers’ depressive symptoms were positively associated with children/early adolescents’ rumination about personal life and rumination about school issues. Conversely, an adequate and positive family functioning was negatively correlated with both school-related rumination and rumination about personal life. Hierarchical regression analyses pointed to a crucial role of maternal rumination and familiar rigidity in both types of rumination. Personal life-related rumination was also specifically predicted by maternal depression and family enmeshment, whereas school-related rumination was significantly associated with children/early adolescents’ emotional control and gender. Overall, the KRI appears as a promising tool to assess rumination in children/early adolescents. Results suggests partially different pathways to specific forms of ruminative thoughts.     

生活事件对初中生抑郁的影响:自尊和反刍思维的链式中介作用

为了探讨生活事件、自尊、反刍思维和初中生抑郁之间的关系,研究采用青少年生活事件量表、自尊量表、反刍思维量表和儿童抑郁量表对684名初中生进行调查。结果显示：（1）生活事件与初中生抑郁呈显著正相关;（2）自尊和反刍思维在生活事件和初中生抑郁间起链式中介作用。生活事件不仅是触发初中生抑郁的重要外部因素,而且生活事件还会通过影响自尊和经由反刍思维对初中生抑郁产生间接作用。因此,减少和避免生活事件对初中生心理的冲击,增强其自尊水平,调整其负性认知方式是改善和预防初中生抑郁的重要途径。     

The roles of sex, gender, and coping in adolescent depression

This study investigated the roles of coping and masculinity in higher rates of depressive symptoms among adolescent girls, as compared to boys. A model was designed and tested through path analysis, which involved the variables of sex, gender, problem-focused coping, rumination, and distraction. The Reynolds Adolescent Depression Scale and the Bem Sex Role Inventory, as well as a measure of coping with general stressors was completed by 246 adolescents. Results showed that adolescent girls were more depressed than boys, and that girls used more emotion-focused and ruminative coping than did boys. Greater degrees of ruminative coping were related to high levels of depressive symptoms. Problem-focused and distractive coping were positively correlated with masculinity and negatively associated with depression. Surprisingly, girls were more likely to use problem-focused coping. Problem-focused and distractive coping were found to mediate the negative relationship between masculinity and depression.     

Anxiety and depression in Greek nursing and medical personnel

The relatively low number of nurses compared to physicians in Greece and the few available studies on the psychological problems of the health professionals led to comparison of anxiety and depression for 76 Greek nursing personnel (20 men, M age: 32.8 yr., SD: 3.8 yr., and 56 women, M age: 36.6 yr., SD: 7.7 yr.) and 66 doctors (35 men, M age: 35.9 yr., SD: 8.9 yr. and 31 women, M age: 32.7 yr., SD: 8.1 yr.) using validated translations of the Spielberger State-Trait Anxiety Inventory and the Beck Depression Inventory. Male nurses had the lowest scores on trait anxiety, while female doctors had the highest scores, followed by female nurses. Depression scores were not different between doctors and nurses, regardless of sex. Age and depression scores were positively correlated (Spearman rho = .31) only for the female nurses. The findings suggest that interventions for diagnosis and stress management in the health-care workplace should be equally targeted for nursing and medical personnel.     

Hooked on a feeling: rumination about positive and negative emotion in inter-episode bipolar disorder

Rumination has been consistently implicated in the onset and maintenance of depression. Less work has examined rumination in the context of bipolar disorder, especially rumination about positive emotion. The present study examined rumination about negative and positive emotion in interepisode bipolar disorder (BD; n = 39) and healthy controls (CTL; n = 34). Trait rumination about positive and negative emotion, as well as experiential and physiological responses to a rumination induction, was measured. Illness course was also assessed for the BD group. Results indicated that the BD group reported greater trait rumination about positive and negative emotion compared with the CTL group, though no group differences emerged during the rumination induction. For the BD group, trait rumination about positive and negative emotion, as well as increased cardiovascular arousal (i.e., heart rate), was associated with greater lifetime depression frequency; trait rumination about positive emotion was associated with greater lifetime mania frequency. These findings suggest that interepisode BD is associated with greater rumination about positive and negative emotion, which in turn is associated with illness course.     

Association among items from the self-report version of the Hamilton Depression Scale (Carroll Rating Scale) and respondents' sex

The association among items of the self-reported version of the Hamilton Depression Scale (Carroll Rating Scale), answered according to a memory of a maximally disturbing event experienced, and respondents' sex was examined in a nonclinical sample of 320 college students, 164 women (M age=21.7 yr., SD=3.6) and 156 men (M age=23.5 yr., SD=5.8). An assessment of sex bias was also evaluated. Multiple regression analysis showed that statements regarding unhappiness, urge to cry, dizziness and faintness, and waking in the middle of the night were significantly associated with women. Removal of these items from the Carroll Rating Scale Total scores eliminated the sex differences in depression rates. Items that displayed significant sex bias were those regarding behavior and emotions commonly attributed to women within the general population.     

Cognitive processes in hoarding: The role of rumination

Rumination, defined as an individual's repetitive negative cognitions of upsetting symptoms in response to distress, has been established as an important cognitive vulnerability factor within various forms of psychopathology. Despite compelling data to suggest that rumination is associated with a number of mood and anxiety-related conditions, no research to date has examined the relationship between rumination and hoarding. Participants consisted of 275 undergraduate students as well as 106 individuals recruited from the community to participate in a larger randomized clinical trial investigating the effects of a computerized treatment targeting specific risk factors associated with anxiety and suicide. Consistent with initial prediction, results indicated that rumination was a significant predictor of hoarding severity, even after controlling for overall general levels of depression. These findings add to a growing body of literature identifying various cognitive vulnerability factors important for the development and maintenance of hoarding. Increasing our knowledge of cognitive vulnerability factors has import implications for the prevention and treatment of anxiety disorders.
