Positive affectivity and attentional control moderate the link between negative affectivity and depressed mood

Research and theory suggest that deficits in trait positive affectivity (PA) and in capacity for executive control of attention (i.e., attentional control or AC) may each intensify risk for depressive symptoms associated with high trait negative affectivity (NA). In contrast, high levels of PA and AC should protect against that risk. However, prospective tests of such predictions are rare. Furthermore, if PA and AC both modulate NA-related risk, it remains to be seen if those effects are independent and complementary or if they operate in an overlapping manner. This study assessed baseline temperament and change in depressed mood across one month in a sample of 125 adolescents. Results supported both PA and AC as modulators of NA’s association with changes in depressed mood. Furthermore, results suggested that these modulating effects are largely non-overlapping and complementary, such that when both PA and AC are low, high NA predicts increases in depressed mood. In contrast, high NA predicts decreases in depressed mood when both PA and AC are high. Limitations of these findings, directions for future research, and implications for prevention are discussed.     

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.

Reactive and self-regulatory dimensions of temperament: Interactive relations with symptoms of general distress and anhedonia

Converging evidence indicates that shared temperamental diatheses partly underlie the covariance between anxiety and depression. Although developmental psychopathology research suggests that self-regulatory temperament (e.g., effortful control or EC) mitigates reactive risks associated with negative affectivity (NA) and positive affectivity (PA), and their respective counterparts, behavioral inhibition- and activation sensitivity (BIS and BAS), no studies have established EC’s protective effects in adulthood. This study examined concurrent relations between temperament and distress symptoms shared by anxiety and depression, and anhedonic symptoms unique to depression, in young adults. Anticipated two- and three-way interactions emerged supporting EC’s moderating effect between reactive temperament (i.e., high BIS and low BAS) and both symptom dimensions. However, no interactive relations emerged between symptoms and NA, PA, and EC.     

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.     

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.

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 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.     

The role of temperament traits as predictors of depressive symptoms and resilience in adolescents

From the initial sample of 956 adolescents from the Basque Country (Spain), 790 (M_age = 14.56, 49.4% girls) completed at least two waves including Wave 1 (retention rate: 82.6%), analyzing temperament traits as longitudinal predictors of depression and resilience. Positive affectivity (PA) predicted decreased depression and increased resilience, while negative affectivity (NA) had the opposite effect, and effortful control (EC) predicted reduced depression. Results indicated that PA protects adolescents who are low in EC against depression. In contrast, high EC levels worsened the damaging effect of NA on depression. Resilience and depression were bidirectionally associated and mediated the effects of temperament traits. Findings highlight the need to consider the effect of the complex interplays between temperament traits on resilience and depression improvement.     

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.     

Longitudinal Study of Life Events,Well-Being,Emotional Regulation and Depressive Symptomatology

Etiological research regarding adolescent depression is relatively recent and longitudinal studies are needed to explicate the mechanisms by which risk and protective factors impact the development of depression. This investigation evaluated the effects of time 1 predictors (e.g., depressive symptoms, life events, subjective well-being, and emotion regulation strategies) on depressive symptoms assessed at time 2 (1 year later). The sample comprised 182 Portuguese adolescents, aged 12–16. Time 1 depressive symptoms and psychological well-being were significant predictors of time 2 depressive symptoms. Time 1 rumination predicted time 2 depressive symptoms, but time 2 brooding mediated this effect. Time 1 life events did not predict time 2 depressive symptomatology. This study identified several factors that seem to play an important role in the development of depressive symptomatology. Previous depressive symptomatology and well-being had a significant effect in this process and the relationship between rumination in time 1 and depressive symptoms at time 2 (1 year later) was fully mediated by brooding at time 2. Given these results, implications for prevention and treatment of depression include addressing risk factors like early depressive symptoms, rumination and brooding, and increasing the protective effect of psychological well-being.     

Mapping the interplay among cognitive biases,emotion regulation,and depressive symptoms

Cognitive biases and emotion regulation (ER) difficulties have been instrumental in understanding hallmark features of depression. However, little is known about the interplay among these important risk factors to depression. This cross-sectional study investigated how multiple cognitive biases modulate the habitual use of ER processes and how ER habits subsequently regulate depressive symptoms. All participants first executed a computerised version of the scrambled sentences test (interpretation bias measure) while their eye movements were registered (attention bias measure) and then completed questionnaires assessing positive reappraisal, brooding, and depressive symptoms. Path and bootstrapping analyses supported both direct effects of cognitive biases on depressive symptoms and indirect effects via the use of brooding and via the use of reappraisal that was in turn related to the use of brooding. These findings help to formulate a better understanding of how cognitive biases and ER habits interact to maintain depressive symptoms.     

Ruminative subtypes and coping responses: Active and passive pathways to depressive symptoms

Individuals draw on a variety of cognitive strategies—some active, some passive—as a way of coping with stress and dysphoria. Previous research suggests that the impact of rumination—one such strategy—on depression depends on whether rumination takes the passive form of brooding versus the more active form of reflection. This study tests whether brooding and reflection explain the effects of passive versus active coping responses, respectively, on depressive symptoms. In an undergraduate sample (n=284), brooding partially mediated the relationship between passive coping and depressive symptoms, whereas reflection did not. Reflection moderated the relationship between active coping and symptoms, such that low active copers who were high in reflection endorsed more symptoms than those low in reflection. Brooding and reflection may operate within cognitive–behavioural response pathways characterised by an active/passive distinction. Whether reflection is maladaptive likely depends on the active nature of the surrounding coping response.     

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.     

Early manifestations of childhood depression: influences of infant temperament and parental depressive symptoms

In this longitudinal study, 83 parents of infants between 3 and 12 months completed questionnaires assessing demographic information, infant temperament, and maternal depression. When these children were at least 18 months of age, parents completed follow‐up questionnaires assessing toddler temperament and depression‐like symptoms. We were primarily interested in the contributions of infant temperament and maternal depression to toddler depressive problems, and the analytic strategy involved controlling for toddler temperament in order to isolate the influence of infancy characteristics. The findings indicated that lower levels of infant regulatory capacity and greater severity of maternal depression were predictive of toddler depression‐like symptoms. Moderator effects of infant temperament were also examined, with the negative affectivity * maternal depression interaction emerging as significant. Follow‐up analyses indicated that the risk for early manifestations of depression was attenuated for children with lower negative affectivity in infancy and parents who reported lower levels of their own depressive symptoms; conversely, children exhibiting higher infant negative emotionality had higher levels of depression‐like symptoms as toddlers, regardless of their parents' level of depression. The present findings further suggest that parental depressive symptoms need not be ‘clinically significant’ to predict toddler affective problems. Copyright © 2008 John Wiley & Sons, Ltd.     

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.     

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.

Perinatal depression influences on infant negative affectivity: Timing,severity, and co-morbid anxiety

Accumulating evidence suggests that antenatal depression predicts infants’ negative affectivity, albeit with variable effect sizes. With a prospective longitudinal design, we sought to explain that variability by addressing questions about timing of the depression across pregnancy and the early postpartum, the role of high symptom levels relative to diagnosed depression, comorbidity with anxiety, and the potential mediating role of neuroendocrine functioning. Primiparous women (n = 77) with histories of depression prior to pregnancy were assessed for cortisol levels monthly beginning by mid-pregnancy. Depression symptom levels and diagnostic status were similarly assessed monthly in pregnancy and also until infants reached three months of age, when mothers completed the Infant Behavior Questionnaire-Revised to measure infant negative affectivity. Antenatal depression symptoms and infant negative affectivity were positively associated (r = .39). Controlling for depression symptom levels in other trimesters, only second trimester depression symptoms predicted higher infant negative affectivity (β = .44). With postpartum depression symptom levels in the model, only antenatal depression symptoms predicted infant negative affectivity (β = .45). In the context of depression, neither antenatal anxiety symptoms nor anxiety disorder diagnosis were associated with infant NA scores. The hypothesized role of elevated maternal cortisol as a mechanism for the association between antenatal depression and infant NA was not supported. Our findings contribute to efforts to more precisely identify infants of perinatally depressed mothers who are at greater risk for elevated negative affectivity, suggesting a window of vulnerability in mid pregnancy and the need for further study of potential mechanisms.     

Hope,Social Support,and Postpartum Depression: Disentangling the Mediating Effects of Negative Affectivity

We examined the potentially mediating effects of negative affectivity (NA) on the hope–depression relationship among a sample of postpartum women. We also assessed the social support reported by these women and examined the possible mediating effects of NA on the social support–postpartum depression relationship. Correlational analyses of data obtained from women (N = 98) who had given birth in the previous 6 months revealed that NA did not mediate either hope or social support in the prediction of postpartum depression. Hope accounted for a significant degree of variance in postpartum depression. These data suggest that hope has palliative effects among women following childbirth and these effects are not nullified or explained by emotional predispositions.
