Pathways linking temperament and depressive symptoms: a short-term prospective diary study among adolescents

The current study examined mechanisms through which trait negative affectivity (NA) and effortful control (EC) prospectively predict increases in depressive symptoms in a community sample of 110 adolescents (mean age=16.40 years) in a 9-week, multi-wave diary study. We hypothesised youth with high NA and low EC would experience greater increases in depressive symptoms because they generate more maladaptive cognitive responses to stress. NA predicted greater event-specific rumination and negative cognitive style across the study period. After controlling for trait cognitive vulnerabilities, only event-specific rumination mediated the effect of NA on subsequent depressive symptoms, suggesting that high-NA youth are more likely to ruminate about stressful events, which then predicts increases in depressive symptoms. EC did not moderate the effects of NA on either depressive symptoms or cognitive responses to stress. Results are discussed in terms of vulnerability-stress models linking temperament and depressive symptoms in adolescence.     

Testing the cognitive catalyst model of depression: does rumination amplify the impact of cognitive diatheses in response to stress?

Recent studies have found that rumination functions as a catalyst of cognitive vulnerability to depression. Specifically, these studies have reported synergistic effects between rumination and negative cognitive content (beliefs and attitudes), such that rumination amplifies the association between negative cognitive content and depression (Ciesla & Roberts, 2002, 2007; Robinson & Alloy, 2003). The current study extended this work by testing whether cognitive vulnerability involving the combination of negative cognitive content and rumination increases the impact of stress on the course of depressive symptoms. One hundred ninety-one college students with elevated depressive symptoms participated in a two-wave longitudinal study. Results indicate that the maintenance of depressive symptoms was predicted by the three-way interaction of negative cognitive content, rumination, and stressful life events. More specifically, students who endorsed both maladaptive cognitive content and a tendency to ruminate were particularly vulnerable to the deleterious impact of life stress.     

Cognitive mechanisms linking low trait positive affect to depressive symptoms: A prospective diary study

Low trait positive affect represents an affective vulnerability to depression, but little research has examined mechanisms linking low trait positive affect to depressive symptoms. The current study investigated whether the cognitive strategies of dampening and positive rumination mediated the prospective association between low trait positive affect and depressive symptoms. Participants were 209 undergraduate students who participated in an eight-week online study. Depressive symptoms and trait temperament were assessed at baseline, followed by seven weekly questionnaires which assessed cognitive strategies in response to weekly events and weekly depressive symptoms. Data were analysed using multilevel modelling following the mediation approach proposed by Nezlek. Results indicated that low trait positive affect significantly predicted less positive rumination but not greater dampening in response to weekly positive events. Less positive rumination in response to weekly positive events partially mediated the association between low trait positive affect and greater depressive symptoms across the study.     

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.     

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.     

Cognitive Vulnerabilities as Predictors of Stress Generation in Early Adolescence: Pathway to Depressive Symptoms

Although individuals with depression have been found to experience a higher rate of stress in their lives, it remains unclear to what extent other personal characteristics may contribute to stress generation. The current study extended past research by examining the effects of two theoretically and empirically supported cognitive vulnerabilities to depression (negative cognitive style and rumination) as predictors of dependent interpersonal and achievement events, independent events, and relational peer victimization. In a diverse sample of 301 early adolescents (56 % female; M_age?=?12.82 years), we found that negative cognitive style prospectively predicted the experience of dependent interpersonal stress and relational victimization, and that rumination did not predict stress in any of the domains. Furthermore, the occurrence of intervening stress mediated the associations between negative cognitive style and subsequent depressive symptoms. Additionally, whereas negative cognitive style predicted relational victimization among both boys and girls, girls were particularly vulnerable to developing depressive symptoms following the occurrence of relational victimization. Thus, a negative cognitive style may contribute to the occurrence of stressful events, which in turn increases depressive symptoms. Girls may be particularly reactive to relational victimization, representing one pathway through which sex differences in depression may emerge.     

Temperament and Risk for Depressive Symptoms in Adolescence: Mediation by Rumination and Moderation by Effortful Control

The present study examined the relations between temperament, ruminative response style and depressive symptoms both cross-sectionally and prospectively (1 year follow-up) in a community sample of 304 seventh- through tenth-graders. First, higher levels of negative affectivity (NA), lower levels of positive affectivity (PA) and lower levels of effortful control (EC) were found to be associated with higher levels of depressive symptoms. Second, the association between NA and PA on the one hand and depressive symptoms on the other was significantly moderated by level of EC (low PA and high NA are associated with depressive symptoms only if EC is low) and these relations were moderated by sex in the cross-sectional data. In the prospective data, T1 depressive symptoms and PA predicted T2 depressive symptoms; with EC approaching significance. Third, rumination also predicted T1 as well as T2 depressive symptoms. Finally, support was found for a model of moderated mediation: higher levels of NA were associated with higher levels of ruminative response style, which was in turn related to more depressive symptoms but only in individuals with low EC and this was true for the cross-sectional as well as the prospective data albeit with noteworthy differences in pattern. These findings confirm and extend previous findings on the associations between temperament, response styles and depression in adolescence and, as such, add to the growing body of research providing support for the applicability of cognitive vulnerability theories to depression in younger populations.

Responses to Positive Affect Predict Mood Symptoms in Children Under Conditions of Stress: A Prospective Study

Rumination to negative affect has been linked to the onset and maintenance of mood disorders in adults as well as children. Responses to positive affect have received far less attention thus far. A few recent studies in adults suggest that responses to positive affect are involved in the development of both depressive and hypomanic symptoms, but thus far no study has investigated their role in childhood mood problems. The purpose of the present study was to validate a child version of the Responses to Positive Affect questionnaire and examine the extent to which responses to positive affect prospectively predict mood symptoms over a 3-month interval. The Responses to Positive Affect questionnaire for Children was found to assess two types of responses to positive affect: Positive Rumination and Dampening. Both subscales showed sufficient internal consistency and moderate stability over a 3-month interval. Low levels of positive rumination and high levels of dampening were concurrently associated with depressive symptoms, over and above responses to negative affect. Importantly, low levels of positive rumination also predicted increases in depressive symptoms over a 3-month interval over and above baseline symptoms in children reporting high levels of stress. Both positive rumination and dampening were positively related to concurrent hypomanic symptoms and high levels of positive rumination predicted increases in hypomanic symptoms over a 3-month interval over and above baseline symptoms in children reporting high levels of stress. The results underscore the added value of assessing responses to positive affect in addition to responses to negative affect.     

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.     

Dampening and brooding jointly link temperament with depressive symptoms: A prospective study

Integrated affective-cognitive models of depression suggest that the effects of trait temperament (low positive affectivity (PA) and high negative affectivity (NA)) on depressive symptoms may be mediated by maladaptive cognitive strategies. Research and theory suggest that the effect of NA on depression is mediated by brooding and the effect of PA on depression is mediated by dampening. Despite correlations among these constructs, no studies have examined joint contributions of PA, NA, brooding, and dampening on depression. The present study examined the effects of NA and PA on prospective increases in depressive symptoms, and whether effects were mediated by brooding and dampening. Hypotheses were tested in an eight-week study of 333 young adults; depressive symptoms were assessed at weeks one and eight. Participants reported their use of dampening and brooding in response to ideographically identified weekly events in weeks two through seven. Results suggest that the effect of PA on increases in depressive symptoms was mediated by use of dampening and the effect of NA on increases in depressive symptoms was mediated by use of both brooding and dampening. Future research should consider temperament traits and cognitive strategies jointly to understand the development and maintenance of depression.     

The association between temperament and depressive symptoms in adolescence: Brooding and reflection as potential mediators

This study examined whether rumination subtypes (brooding and reflection) mediated prospective associations between temperament (negative emotionality and positive emotionality) and depressive symptoms in a community sample of 423 adolescents. Effortful control and sex were examined as potential moderators of the mediated pathway. Youth self-reported negative emotionality (NE), positive emotionality (PE), and effortful control (EC) at age 12; brooding and reflection subtypes of rumination at age 14; and depressive symptoms at ages 12, 14, and 15. Hierarchical linear regression analyses indicated that, controlling for initial levels of depressive symptoms, high NE, but not low PE, predicted increases in depressive symptoms from age 12 to age 15. Brooding, but not reflection, mediated the association between NE and depressive symptoms. Neither sex nor EC moderated either indirect pathway in the mediated model. The results confirm and extend previous findings on the association between affective and cognitive vulnerability factors in predicting depressive symptoms in adolescence.

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.     

Specificity of cognitive and behavioral variables to Positive and Negative Affect

The Tripartite Model proposes that a combination of greater Negative Affect (NA) and reduced Positive Affect (PA) contributes to depressive symptoms. The purpose of this study was to test a model of affective experience in which cognitive variables (i.e., negative cognitions and appraisals) are uniquely related to NA but not PA, and in which behavioral variables (i.e., activity participation) are uniquely associated with PA but not NA. Participants included 88 spousal Alzheimer caregivers (mean age = 74 years). Multiple regression models, in which negative cognitions (i.e., helplessness, blames self, and negative appraisals) and activity participation (i.e., frequency of engaging in social and recreational activities) were used to predict depressive symptoms, PA and NA. Results indicated that while helplessness, blaming oneself, negative appraisals, and activity participation all significantly predicted depressive symptoms, only negative cognitive variables significantly predicted NA, and only activity participation significantly predicted PA. These data confirm that depressive experience consists of two relatively independent components - increased Negative Affect and reduced Positive Affect - which have unique correlates in negative cognitions and activity participation. If confirmed, the findings suggest the utility of focusing interventions on each of these components in the management of depressive symptoms.     

Trait rumination and response to negative evaluative lab-induced stress: neuroendocrine,affective, and cognitive outcomes

Theoretical models of depression posit that, under stress, elevated trait rumination predicts more pronounced or prolonged negative affective and neuroendocrine responses, and that trait rumination hampers removing irrelevant negative information from working memory. We examined several gaps regarding these models in the context of lab-induced stress. Non-depressed undergraduates completed a rumination questionnaire and either a negative-evaluative Trier Social Stress Test (n?=?55) or a non-evaluative control condition (n?=?69), followed by a modified Sternberg affective working memory task assessing the extent to which irrelevant negative information can be emptied from working memory. We measured shame, negative and positive affect, and salivary cortisol four times. Multilevel growth curve models showed rumination and stress interactively predicted cortisol reactivity; however, opposite predictions, greater rumination was associated with blunted cortisol reactivity to stress. Elevated trait rumination interacted with stress to predict augmented shame reactivity. Rumination and stress did not significantly interact to predict working memory performance, but under control conditions, rumination predicted greater difficulty updating working memory. Results support a vulnerability-stress model of trait rumination with heightened shame reactivity and cortisol dysregulation rather than hyper-reactivity in non-depressed emerging adults, but we cannot provide evidence that working memory processes are critical immediately following acute stress.     

Co-Rumination Exacerbates Stress Generation among Adolescents with Depressive Symptoms

Through stress generation, individuals’ own thoughts and behaviors can actually lead to increases in their experience of stress. Unfortunately, stress generation is especially common among individuals who are already suffering from elevated depressive symptoms. However, despite the acknowledgement that some individuals with depressive symptoms generate greater stress than others, few studies have identified specific factors that could exacerbate stress generation among individuals with depressive symptoms. The present study examines co-rumination as a factor that might exacerbate stress generation among adolescents with depressive symptoms using a short-term longitudinal design. Considering these processes among adolescents was critical given that many youth experience increases in depressive symptoms at this developmental stage and that co-rumination also becomes more common at adolescence. Participants were 628 adolescents (326 girls; 302 boys) who reported on their depressive symptoms, experiences of stress, and co-rumination with a best friend. Interpersonal stressors (peer and family stress) and non-interpersonal stressors (school and sports stress) were assessed. Consistent with past research, adolescents with depressive symptoms experienced greater interpersonal and non-interpersonal stress over time. Importantly, co-rumination interacted with both depressive symptoms and gender in predicting increases in peer stress. Depressive symptoms predicted the generation of peer stress only for girls who reported high levels of co-rumination with friends. Implications for protecting youth with depressive symptoms against stress generation are discussed.     

Obsessive-Compulsive and Depressive Symptoms: The Role of Depressive Cognitive Styles

Obsessive-compulsive disorder (OCD) commonly co-occurs with depression, resulting in heightened severity and poorer treatment response. Research on the associations between specific obsessive-compulsive symptoms (OCS) and depressive symptoms has utilized measures that have not fully considered the relationship across OCS dimensions. Little is known about which factors explain the overlap between OCS and depressive symptoms. OCS and depressive symptoms may be related via depressive cognitive styles, such as rumination or dampening (i.e., down-regulating positive emotions). We evaluated the associations of OCS dimensions with depressive symptoms and cognitive styles. We also examined the indirect effects of rumination and dampening in the relationship between OCS and depressive symptoms. Participants (N = 250) completed questionnaires online. Greater depressive symptoms, rumination, and dampening were associated with greater levels of all OCS dimensions. Path analysis was utilized to examine a model including the direct effect of depressive symptoms on overall OCS and two indirect effects (through rumination and dampening). There was a significant indirect effect of depressive cognitive styles on the relationship between OCS and depressive symptoms, through rumination and dampening. Replication in a clinical sample and experimental manipulations may bear important implications for targeting depressive cognitive styles in treatments for OCD and depression.     

The effects of rumination and negative cognitive styles on depression: a mediation analysis

Research on cognitive models of depression has identified negative cognitive styles and rumination as risk factors for depression. The present study examined the hypothesis that rumination mediates the effect of negative cognitive styles on depression. Specifically, we evaluated the differential effects of two aspects of rumination, characterized by brooding and reflection, on the relationship between negative cognitive styles and level of depressive symptoms. A total of 115 college students and 38 patients suffering from depressive disorders completed a battery of questionnaires measuring levels of depressive symptoms, brooding, reflection, and negative cognitive styles. The results support the notion that there exist two distinct dimensions of rumination and that, of the two, it is brooding and not reflection that mediates the relationship between negative cognitive styles and depression and contributes to its negative outcomes.     

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.
