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.

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

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

Cognitive Vulnerability to Emotional Symptoms: Reconsidering the Role of Worry and Rumination

The present study explored the pathways whereby cognitive variables (worry, rumination) may explain the relation between neuroticism and emotional symptoms in a community sample of adults (N?=?499). All participants completed a battery of questionnaires including measures of neuroticism, worry, rumination, anxiety and depression. Multiple mediation and moderated mediation analyses were used. Worry was a common pathway explaining the effect of neuroticism on both anxiety and depressive symptoms. The brooding subtype of rumination significantly mediated the relation between neuroticism and anxiety symptoms, but the reflection subtype did not have a mediating effect. Although worry by itself mediated the association between neuroticism and anxiety symptoms, it required a certain level of brooding to exert its mediating effect on the relation between neuroticism and depressive symptoms. The results are discussed in light of previous research and recent developments in treatment. Clinical implications and suggestions for future research are also discussed.     

Associations Between Mixed-Gender Friendships,Gender Reference Group Identity and Substance Use in College Students

We investigated the associations between same-gender friendship, gender reference group identity, and substance use in college students (54 % male, M age?=?19.23, SD?=?1.23) from the northeastern United States using an online survey. Male students reported greater weekly marijuana, but not alcohol use than female students. Regression analyses revealed that having a greater proportion of same-gender friendships was associated with greater weekly alcohol use for male students and lesser weekly alcohol and marijuana use for female students. Gender reference group identity was negatively associated with weekly marijuana use for male and female students. For female students, gender reference group identity mediated the association between proportion of same-gender friendships and weekly marijuana use. Our study highlights the importance of considering the social context (e.g., the gender of friends) and individual variables relating to gender (e.g. gender reference group identity) in substance use research. Our findings fit within social constructionist models of social development that suggest participation in gendered contexts (e.g., same-gender or other-gender-peer contexts) over time cue gender-typed behaviors such as using marijuana.     

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.     

Psychopathy and Functions of Aggression in Emerging Adulthood: Moderation by Anger Rumination and Gender

Psychopathy has been previously identified as a risk factor for aggression (Porter and Woodworth 2006). However, few studies have considered specific relationships with functional subtypes of aggression, or how gender and anger rumination affect these relationships in emerging adulthood. We hypothesized that primary psychopathy would be uniquely related to proactive aggression (PA) and secondary psychopathy to reactive aggression (RA), and that these relationships would be amplified by anger rumination, and potentially influenced further by gender. Undergraduate students (N = 610; 73.3 % female) ages 18–20 completed self-report measures of anger rumination, psychopathy, and aggression, and hypotheses were tested using hierarchical regression. As predicted, anger rumination enhanced the association between secondary psychopathy and RA. It also amplified the relationship between primary psychopathy and PA, but only at very high levels of anger rumination. Gender moderated interactions between primary and secondary psychopathy on aggression. For men, primary psychopathy attenuated the secondary psychopathy – RA relationship, but not for women. These findings fill an important gap in the literature by demonstrating how tendencies to ruminate on anger and psychopathic traits interact to influence functional subtypes of aggression in young men versus women.     

Gender differences in rumination: A meta-analysis

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

Callous-Unemotional Traits as Unique Prospective Risk Factors for Substance Use in Early Adolescent Boys and Girls

Youth with elevated conduct disorder (CD) symptoms who also have callous-unemotional (CU) traits exhibit more antisocial behavior than youth without CU traits. However, evidence regarding whether CU traits increase risk of substance use over and above CD symptoms, and whether these associations differ for boys and girls, is scarce. Using the Developmental Pathways Project sample of 521 middle school students, we examined whether adolescent- and parent-reported CU traits measured in 6th grade prospectively predicted the onset and recurrence of substance use and use-related impairment by 9th grade. We also examined the degree to which CU traits uniquely predicted substance use and impairment over and above CD symptoms, as well as whether gender moderated these associations. Results indicated that adolescent-reported CU traits increased the likelihood of substance use and impairment onset and recurrence by 9th grade. Analyses revealed that CD symptoms accounted for prospective associations between adolescent-reported CU and substance use, but gender moderated these associations. Boys with elevated CU traits and CD symptoms were not more likely to report alcohol use onset or recurrence, but they were at highest risk of recurrent marijuana use, use of both alcohol and marijuana, and use-related impairment by 9th grade. Girls with low CU traits and high CD symptoms were most likely to report onset and recurrent use of alcohol, as well as recurrent marijuana use, use of both substances and impairment. Study findings highlight the importance of accounting for CD symptoms and gender when examining links between CU traits and substance use in early adolescence.     

Alcohol-aggression expectancies and dispositional rumination moderate the effect of alcohol consumption on alcohol-related aggression and hostility

Alcohol consumption increases aggression, but only in some drinkers. This study extends previous work to show how expectancies for alcohol-induced aggression and dispositional rumination moderate the link between alcohol consumption and alcohol-related aggression and hostility in a sample of 285 men and women. Alcohol-aggression expectancies and quantity of alcohol interacted to predict alcohol-related hostility and aggression. Trait rumination moderated the effect of alcohol consumption on aggressive acts. Finally, women who ruminated were more likely to report alcohol-related aggression than were men who ruminated. These results suggest that alcohol expectancies for aggression and rumination constitute two important cognitive facilitators of alcohol-related aggression and hostility, and that gender plays an important role in these relations.     

Internalizing and Externalizing Problem Behavior: a Test of a Latent Variable Interaction Predicting a Two-Part Growth Model of Adolescent Substance Use

Externalizing symptoms robustly predict adolescent substance use (SU); however, findings regarding internalizing symptoms have been mixed, suggesting that there may be important moderators of the relationship between internalizing problems and SU. The present study used a longitudinal community sample (N?=?387, 55% female, 83% White) to test whether externalizing symptoms moderated the relationship between internalizing symptoms and trajectories of alcohol and marijuana use from early (age 11–12 years old) to late (age 18–19 years old) adolescence. Two-part latent growth models were used to distinguish trajectories of probability of use from trajectories of amount of use among users. Results suggested that externalizing symptoms moderated the association between internalizing symptoms and probability of alcohol, but not marijuana use. The highest probability of alcohol use was observed at high levels of externalizing symptoms and low levels of internalizing symptoms. A negative protective effect of internalizing symptoms on probability of alcohol use was strongest in early adolescence for youth high on externalizing symptoms. Although moderation was not supported for amount of use among users, both domains of symptomology were associated with amount of alcohol and marijuana use as first-order effects. High levels of externalizing symptoms and low levels of internalizing symptoms were associated with high levels of amount of use among users. These findings suggest that developmental models of substance use that incorporate internalizing symptomology should consider the context of externalizing problems and distinguish probability and amount of use.     

Psychosocial correlates of depressive rumination

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

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.     

Hope as a Moderator of the Associations Between Common Risk Factors and Frequency of Substance Use Among Latino Adolescents

Ample research suggests that delinquency, depressive symptoms, and peer substance use are common risk factors associated with adolescent substance use. However, the factors that may help to buffer the deleterious effects of these risk factors on adolescent substance use, such as hope, have yet to be examined. The current study evaluated hope as a moderator of the associations between these common risk factors and frequency of substance use (alcohol, tobacco, and marijuana) in a sample of Latino high school students (M _age ?=?16.14 years, SD?=?1.30; 55 % female). Findings indicated that the influence of delinquency on frequency of tobacco and marijuana use depended on levels of hope, with delinquency only positively associated with frequency of use when levels of hope were low. Additionally, hope moderated the association between depressive symptoms and alcohol use, such that depressive symptoms were only positively associated with frequency of alcohol use when levels of hope were low. Results and their implications for intervention are reviewed.     

Brooding and Reflection as Subtypes of Rumination: Evidence from Confirmatory Factor Analysis in Nonclinical Samples using the Dutch Ruminative Response Scale

Previous research has shown that depressive rumination is an important vulnerability factor for experiencing depressive symptoms. The most widely used measure to assess depressive rumination is the Ruminative Response Scale (RRS). According to Treynor et al. (Cognitive Therapy and Research 27:247–259, 2003), the RRS contains two subscales, reflecting two different rumination subcomponents: brooding and reflection. The present study examined the psychometric properties of the RRS in two samples (N = 432 and N = 407). Based on a confirmatory factor analysis (CFA), results confirmed that a two-dimensional model with brooding and reflection factors provided an adequate fit to the data. Reliability, convergent and discriminant validity of the rumination subcomponents were appropriate. Furthermore, brooding but not reflection predicted depressive symptoms prospectively, even when accounting for concurrent depressive feelings. The results provide the first confirmatory factor-analytical support for the widely assumed two-factor model of the RRS and add to the accumulating body of evidence supporting the multidimensional nature of depressive rumination.     

Brooding and reflection: rumination predicts suicidal ideation at 1-year follow-up in a community sample

The cognitive processes underlying suicidal thinking and behavior are not well understood. The present study examined brooding and reflection, two dimensions of rumination, as predictors of suicidal ideation among a community sample of 1134 adults. Participants completed self-report measures of rumination and depression, and a semi-structured clinical interview that included an assessment of suicidal ideation, at baseline and 1-year follow-up. Brooding was more strongly related to degree of ideation at baseline than was reflection. However, both brooding and reflection predicted whether an individual thought about suicide at 1-year follow-up, even after adjusting for baseline suicidal ideation. Symptoms of depression mediated the relationship between brooding and ideation but not that between reflection and ideation. Implications for the nature of thought processes that result in suicidal thinking are discussed.     

Social Anxiety and the Quality of Everyday Social Interactions: The Moderating Influence of Alcohol Consumption

Most research on the link between social anxiety and alcohol consumption has examined problematic outcomes without consideration of potential adaptive functions. Alcohol is an anxiolytic that has the short-term benefit of reducing anxiety; consumption may act as a social lubricant that facilitates higher quality social interactions. Using experience-sampling methodology, we examined how consuming alcohol attenuates the adverse effects of social anxiety in naturally occurring social interactions. Participants (N = 160) completed demographic and trait measures, then completed daily assessments for 14 consecutive days. Results from multilevel model analyses revealed that during face-to-face social interactions, state social anxiety was inversely related to 10 indicators of healthy social interactions (e.g., enjoyment, laughter, feelings of acceptance). Alcohol consumption moderated seven of these associations, such that when participants consumed alcohol in social situations, state social anxiety was no longer associated with social interaction quality. The quantity of alcoholic drinks consumed moderated two of these associations. Furthermore, we found evidence for directionality, such that social anxiety in a given social interaction predicted alcohol consumption in a subsequent social interaction, but not the reverse (i.e., alcohol consumption did not prospectively predict state social anxiety). In social situations that involved alcohol, experiences of social anxiety no longer thwarted one’s ability to derive social benefits. These results should be interpreted in the context of a participant sample with relatively low levels of trait social anxiety and frequency of alcohol use. Nonetheless, obtaining social rewards may be a reinforcement mechanism that maintains the link between social anxiety and alcohol consumption.     

Depressive Rumination and Co-Morbidity: Evidence for Brooding as a Transdiagnostic Process

A sample of 116 patients with unipolar mood disorders referred to a specialist research clinic were assessed to investigate (a) whether rumination is a transdiagnostic process that is related to co-morbid Axis I and II symptoms and diagnosis in depressed patients; (b) whether common findings in the depressive rumination literature could be replicated in a recurrent depressed sample. Consistent with the transdiagnostic hypothesis, rumination was positively associated with both depression and anxiety, brooding was related to co-morbid obsessive-compulsive disorder and generalized anxiety disorder, and rumination was associated with traits associated with borderline personality disorder, most notably self-report of unstable relationships and inconsistent sense of self. As predicted, rumination was equivalent in currently depressed and formerly depressed patients, suggesting that rumination is not simply dependent on mood state or clinical status. As predicted, the brooding subtype most strongly correlated with depressed and anxious symptoms, consistent with previous observations that brooding is the more maladaptive form of rumination. As predicted, rumination was associated with reports of sexual abuse. Inconsistent with previous findings, there was no gender difference in rumination.
