Problem Talk in Adolescence: Temperament and Attachment as Predictors of Co-Rumination Trajectories in Boys and Girls.

Co-rumination has consistently been shown to be maladaptive in the context of emotional well-being. However, not much is known about factors that predict one's tendency to co-ruminate. The current study investigated temperament, attachment, and gender as predictors of co-rumination trajectories in a sample of 1549 early and middle adolescents from fifth to ninth grade (53.4% girls; Mage = 12.93). Analyses were performed on four waves of data with one-year intervals using multi-level modeling. First, girls were found to be more likely to co-ruminate. Second, high positive affectivity in boys and girls and high effortful control in boys was related to higher co-rumination. Third, high attachment anxiety and high general trust in the availability and support of a mother were predictive of higher co-rumination levels. High attachment avoidance was negatively related to co-rumination in boys. High positive affectivity in boys and girls and high trust in boys predicted decreases in reported co-rumination levels over time. Results highlight differences between boys and girls in factors that predict the tendency to co-ruminate. The current study adds to the literature by helping to identify factors associated with the development of co-rumination, which is a well-established risk factor of internalizing symptoms. Monitoring youth affected with these vulnerabilities may be recommended for prevention efforts.

Impact of stress and parenting on respiratory sinus arrythmia trajectories in early adolescence.

The effects of stress and parenting on 1-year trajectories of physiological emotion regulation capacity among adolescents were examined. Consistent with the vulnerability-stress and allostatic load models, stress (chronic family and marital) was hypothesized to be associated with less favorable trajectories of basal respiratory sinus arrhythmia (RSA) over 1 year. This relationship was further hypothesized to be moderated by parenting practices (warmth, neglect, and rejection) and adolescent sex. Participants included 150 adolescents (51.3% female), 11-15 years of age (M = 13.04, SD = 0.89). Basal RSA and stress were assessed four times across 1 year. Results indicated a significant decrease in RSA over the course of 1 year (ß = -0.15, p = .010). Warm parenting style was associated with lower RSA in environments of low marital stress and was also related with higher RSA in environments of high marital stress (ß = 0.86, p = .021). Rejecting parenting styles were associated with higher RSA in environments of low family stress and lower RSA in environments of high family stress (ß = -0.60, p = .014). These findings may be explained by the Yerkes-Dodson law of optimal stress, suggesting that sufficient environmental challenge is needed to catalyze regulatory development.

Gender Differences in Depression: Biological, Affective, Cognitive, and Sociocultural Factors.

The odds ratio (OR) for gender differences in major depression is 1.95, averaged meta-analytically over all ages and nations. The gender difference appears by age 12, OR = 2.37, and peaks at OR = 3.02 for ages 13-15. Using the ABC (affective, biological, cognitive) model as a framework within a vulnerability-stress approach, we consider the evidence for biological vulnerabilities (genes, pubertal hormones, and pubertal timing), affective vulnerabilities (temperament), and cognitive vulnerabilities (negative cognitive style, objectified body consciousness, and rumination). The impact of stress is central to the vulnerability-stress model, and we review evidence on gender differences in stress exposure, emphasizing gender differences in sex-related traumas such as child sexual abuse and rape. Finally, we examine sociocultural factors that may contribute to the gender difference, including the media and gender inequality. An implication for research methods is that single-gender designs should be questioned. Regarding clinical implications, the vulnerabilities and stressors identified in this review should contribute to personalized interventions with depressed individuals, especially depressed women.

The effect of trauma proximity and ruminative response styles on posttraumatic stress and posttraumatic growth following a university shooting.

OBJECTIVE: Shootings in academic settings are associated with the development of both posttraumatic growth (PTG) and posttraumatic stress (PTS) symptoms (Bardeen, Kumpula, & Orcutt, 2013). Traumatic events can challenge an individual's cognitive framework and contribute to the development of PTS and PTG. Intrusive rumination is thought to increase vulnerability to PTS symptoms, whereas deliberate rumination is likely to be associated with PTG. Literature that serves to distinguish the contextual and intraindividual predictors differentially leading to the development of PTS and PTG symptoms is limited. This cross-sectional study examined the relations between trauma proximity and posttraumatic outcomes as mediated by deliberate and intrusive ruminative responses to a university shooting. We hypothesize that (a) physical and emotional proximity would exert distinct effects on posttraumatic outcomes, (b) the effects of proximity on PTS would be mediated by intrusive rumination, and (c) the effects of proximity on PTG would be mediated by deliberate rumination. METHOD: Three hundred and eighty-five students, faculty, and staff who were exposed to a university campus shooting completed a series of questionnaires 4 months after the event. RESULTS: Emotional proximity was associated with PTS and PTG, whereas physical proximity was only associated with PTS. Of our four hypothesized mediation relationships, intrusive rumination mediated the relationship between physical proximity and PTS, and deliberate rumination mediated the relationship between emotional proximity and PTG. CONCLUSIONS: These results suggest that physical and emotional proximity to a traumatic event uniquely contribute to the development of posttraumatic outcomes and that intrusive rumination promotes maladaptive outcomes, whereas deliberate rumination may promote adaptive outcomes.

Stress and parenting predict changes in adolescent respiratory sinus arrhythmia.

Adolescence is a critical period for the development of physiological emotion regulatory systems. While stressful life experiences are known to inhibit adaptive regulation, less is known about how parental socialization of emotion regulation may affect this relation. We examined the effect of stressful life experiences on changes in the resting respiratory sinus arrhythmia (RSA) levels of 107 (Mage  = 12.84, SD = 0.85) young adolescents over a year, moderated by supportive parental responses to negative emotions. The significant interaction (B = 0.02, p = 0.04) indicated that young adolescents who experienced low levels of supportive parenting in the context of high levels of stressful life experiences showed significant decreases in resting RSA over the year, while adolescents who experienced high levels of supportive parenting showed minimal decreases in RSA. Thus, more supportive parenting significantly compensated for the effect of greater stressful life experiences on changes in resting RSA over time.

Motives for and impairment associated with alcohol and marijuana use among college students.

INTRODUCTION: Alcohol and marijuana use are prevalent on college campuses. As recreational marijuana use is legalized, more undergraduate students may use marijuana in combination with alcohol. The motives for, frequency of, and impairment associated with dual use (alcohol and marijuana) compared to alcohol-only use may differ. We examined motives for, frequency of, and impairment associated with alcohol use and dual use at a university in a state where recreational marijuana has been legalized. METHOD: Undergraduate college students completed an anonymous online survey (N = 430) concerning alcohol and marijuana frequency, motives, and impairment. Students were classified as either alcohol-only users (n = 279) or dual users (n = 151). RESULTS: Analyses indicated that among alcohol-only users, social motives predicted more alcohol use, while among dual users, enhancement motives predicted more alcohol and marijuana use and impairment. Coping motives predicted more marijuana use among dual users, but not more alcohol use. Frequency of alcohol and marijuana use predicted more impairment across both the alcohol-only and dual users. CONCLUSIONS: Future research should examine the influence of marijuana use over time to understand how motives may change for previous alcohol-only users.

Respiratory sinus arrhythmia and adaptive emotion regulation as predictors of nonsuicidal self-injury in young adults.

Research suggests that both respiratory sinus arrhythmia (RSA) and emotion regulation are related to maladaptive outcomes. However, little is known about how these factors jointly contribute to nonsuicidal self-injury (NSSI). We examined how resting RSA and RSA withdrawal to stress predicted NSSI among young adults, and whether adaptive emotion regulation strategies moderated this effect. We examined this relation in a sample of 70 young adults (Mage = 19.25, SDage = 0.92, 94% female), 35 with a recent history of NSSI and 35 who had never engaged in NSSI. Participants completed a baseline questionnaire and lab visit where physiological responses to a social stressor were collected. Results indicated that resting RSA did not predict recent NSSI engagement. However, greater RSA withdrawal to social stress significantly predicted recent NSSI (ß = 1.35 [0.57], Wald χ2 = 5.52 p = 0.02). Further, problem-solving moderated the relation between RSA withdrawal and recent NSSI such that individuals with greater levels of RSA withdrawal were significantly more likely to engage in NSSI if they also reported low problem-solving (ß = -1.44 [0.64], Wald χ2 = 5.16, p = 0.02). In contrast, the effect of greater RSA withdrawal on NSSI was buffered by high problem-solving. Cognitive reappraisal did not moderate the relation between RSA withdrawal and NSSI. These findings suggest that problem-solving may be an important moderator in the relation between physiological reactivity and NSSI. Interventions should help clients with poor self-regulation develop adaptive problem-solving strategies.

Low physiological arousal and high impulsivity as predictors of self-injurious thoughts and behaviors among adolescents.

Self-injurious thoughts and behaviors are used to escape or regulate aversive physiological states during stress. Low sympathetic nervous system arousal during stress has been shown to confer risk. This risk may be exacerbated by trait impulsivity; adolescents high in impulsivity are more likely to rashly use maladaptive regulation strategies. We examined this relationship longitudinally in a sample of adolescents ages 10 to 14 (55.4% female) from the United States. Consistent with our hypothesis, low arousal during stress and high trait impulsivity interacted to predict the use of self-injurious thoughts and behaviors over a six-month period. This study extends and clarifies previous research findings regarding the relationship between physiological arousal and self-injurious thoughts and behaviors.

Physiological Self-Regulation Buffers the Relationship between Impulsivity and Externalizing Behaviors among Nonclinical Adolescents.

Trait impulsivity is a risk factor for rule breaking and aggressive (externalizing) behaviors among nonclinical youth. Buffers of trait-based risk are of practical interest to preventing externalizing behaviors. One such buffer may be the capacity and efforts of a child to self-regulate their physiology. Youth who possess baseline physiological self-regulatory capacities are more likely to maintain adaptive engagement with their environment and may be less prone to impulsively rule break or be aggressive. Similarly, youth who are able to use self-regulatory skills to calm their physiology in times of stress may be less likely to externalize distress. This study examined self-regulatory capacity and efforts as a moderator of the relationship between trait impulsivity and externalizing behaviors, cross-sectionally and prospectively. We hypothesized that the effect of trait impulsivity on externalizing behaviors would depend on the presence of baseline self-regulatory capacity and/or self-regulatory efforts during stress. Participants were 134 nonclinical adolescents (Mage = 12.59, SD = 1.20 51.9% female, 71% Caucasian). Trait impulsivity was measured using a parental report questionnaire. Physiological self-regulatory capacity and efforts were measured through collection of electrocardiogram data during a resting baseline and a stressful, unsolvable anagram task, respectively. Physiological self-regulation was quantified by calculating respiratory sinus arrhythmia scores across baseline and stress tasks. Respiratory sinus arrhythmia is the change in heart rate across the breathing cycle, and is hypothesized to index physiological self-regulation capacity and efforts under specific conditions. The results indicated that physiological self-regulation capacity, but not efforts, moderated the effect of trait impulsivity on externalizing behaviors prospectively. Stronger physiological self-regulatory capacity buffered the effect of greater trait impulsivity. Implications of these findings among typically developing youth are discussed.

Pre-ejection period reactivity to reward is associated with anhedonic symptoms of depression among adolescents.

Pre-ejection period (PEP) reactivity to reward has been posited as a specific index of behavioral approach and incentive motivation, suggesting it might be uniquely associated with the affective and motivational deficits of anhedonia. This study evaluated PEP reactivity to a reward task as a predictor of depressive symptoms among adolescents, examining global depressive symptoms as well as specific anhedonic and nonanhedonic symptoms clusters. Participants included 76 adolescents, ages 11-15 years (52% female). This study found marginal support for an association between PEP reactivity to reward and concurrent anhedonia symptoms, but no association with nonanhedonic or the global scale. Findings are discussed in terms of potential associations between peripheral psychophysiological measures and dopaminergic functioning and also the utility of this measure for future research on anhedonia.

Somatic Symptoms Mediate the Relationship Between Health Anxiety and Health-Related Quality of Life over Eight Weeks.

Previous research has indicated that at clinical levels, health anxiety is cross-sectionally correlated with both somatic symptoms and health-related quality of life (HRQOL). However, research has not tested mediational models of how health anxiety may lead to diminished HRQOL prospectively, and more broadly outside of clinical contexts. In the context of an eight-week prospective diary study of 118 subclinical adults, we examined whether somatic symptoms mediate the relationship between health anxiety and both same-week HRQOL and week-to-week change in HRQOL. Multilevel modelling indicated that somatic symptoms fully mediated the relationship between HA and HRQOL concurrently and over time. Even after accounting for depressive symptoms, individuals who were predisposed to experience illness preoccupation and oversensitivity to bodily sensations were at risk for higher somatic symptoms and thereby poorer levels of perceived health. Thus, both health anxiety and somatic symptoms may be an important target for interventions seeking to improve HRQOL in subclinical populations. Copyright © 2016 John Wiley & Sons, Ltd.

Respiratory sinus arrhythmia as a predictor of self-injurious thoughts and behaviors among adolescents.

Research suggests that self-injurious thoughts and behaviors (SITBs) may function as maladaptive emotion regulation strategies. One psychophysiological index of emotion regulatory capacity is respiratory sinus arrhythmia (RSA). The temporal course of RSA responsivity to a stressor may be characterized by basal RSA, RSA reactivity to stressor, and RSA recovery post-stressor. RSA has been linked to both internalizing and externalizing symptoms in adolescents, but little is known about the relation between RSA and SITBs. Initial research has shown a cross-sectional relation between lower basal RSA and greater RSA reactivity to a sad mood induction and self-injury. To date no prospective research on the relation between RSA and SITBs exists. The current study aims to investigate the prospective relation between RSA and SITBs in a community sample of 108 adolescents (Mage=12.82, SDage=0.82, 53.70% female). At the initial laboratory visit (T1), participants completed an unsolvable anagram stressor task, during which RSA (basal, reactivity, and recovery) was measured. SITBs were assessed at T1 and at the 6-month follow-up (T2). Results indicated basal RSA and RSA reactivity did not significantly predict engagement in SITBs between T1 and T2. Poorer RSA recovery from the stressor task at T1 did significantly predict engagement in SITBs between T1 and T2, over and above depressive symptoms and lifetime history of SITBs. This suggests that adolescents with poor ability to regulate physiologically following a stressor may turn to maladaptive emotion regulation strategies like SITBs.

Examining biological vulnerability in environmental context: Parenting moderates effects of low resting respiratory sinus arrhythmia on adolescent depressive symptoms.

Polyvagal theory suggests that parasympathetic regulation of cardiac function, indexed by resting respiratory sinus arrhythmia (RSA), may be a marker of emotion regulatory capacity and associated with youth psychopathology. Contemporary models of psychopathology suggest that the effects of biological vulnerability may be moderated by developmental context. The aim of the present study was to examine whether parenting, particularly parental responses to youth's negative emotions, moderated the effects of resting RSA on depressive symptoms among early adolescents. We examined resting RSA, depressive symptoms, and parental responses to youth negative emotions among 120 adolescents aged 11-14 years (M = 12.86, SD = .85; 52.5% female). Resting RSA and lack of supportive parenting interacted to predict youth depressive symptoms, such that low resting RSA predicted more depressive symptoms only in the context of low levels of supportive parental responses to youth's negative emotions. By contrast, high resting RSA buffered the effects of low supportive parenting on youth depressive symptoms. These findings highlight the importance of understanding joint contributions of biological vulnerability and developmental context on youth depression outcomes.

Moderating effects of brooding and co-rumination on the relationship between stress and depressive symptoms in early adolescence: a multi-wave study.

The current study investigated brooding and co-rumination as moderators of the relationship between interpersonal and noninterpersonal stress and depressive symptom trajectories. The sample consisted of 368 early adolescents ages 9 to 15 (M = 11.72, 63 % female) who completed self-report measures of brooding, co-rumination, stress, and depressive symptoms at baseline with follow-up assessments of stress and depressive symptoms at 3, 8, and 12 months post-baseline. Data were analyzed using multi-level modeling. Results showed that the association between interpersonal stress and depressive symptoms was stronger for adolescents high on brooding, compared to adolescents low on brooding. Sex moderated a co-rumination × stress interaction, with girls high on co-rumination and boys low on co-rumination reporting the highest levels of depressive symptoms when faced with interpersonal stress across the 1-year study period. These findings shed light on pathways to depressive symptoms in early adolescence and suggest that adolescent boys and girls may differ in these pathways.

Different stressors, different strategies, different outcomes: how domain-specific stress responses differentially predict depressive symptoms among adolescents.

As a time of notably increased stress and a marked rise in depressive symptoms, adolescence is a key period in which to examine how stress is related to mental health outcomes. Many studies examine stress as a unitary construct; however, research suggests that how adolescents respond to stress within different domains may differentially predict depression. The current study used an 8-week weekly diary design to assess how adolescents' cognitive appraisals, rumination, and co-rumination in response to dependent, independent, social, and nonsocial stressors differentially predicted depressive symptoms. Participants were 111 high school students (72% female) ages 14-19 years (mean age 16.4). Results indicated that rumination and co-rumination about dependent and social events, rather than independent or nonsocial events, prospectively predicted depressive symptoms. Negative cognitive appraisals prospectively predicted depressive symptoms regardless of domain. This study provides support for the hypothesis that adolescents' responses to stress in different domains differentially predict depressive symptoms.

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.

Rumination Mediates the Relationship between Infant Temperament and Adolescent Depressive Symptoms.

This study examined prospective associations between negative emotionality, rumination, and depressive symptoms in a community sample of 301 youths (158 females) followed longitudinally from birth to adolescence. Mothers reported on youths' negative emotionality (NE) at age 1, and youths self-reported rumination at age 13 and depressive symptoms at ages 13 and 15. Linear regression analyses indicated that greater NE in infancy was associated with more depressive symptoms at age 15, even after controlling for child gender and depressive symptoms at age 13. Moreover, analyses indicated that rumination significantly mediated the association between infancy NE and age 15 depressive symptoms in the full sample. When analyzed separately by gender, however, rumination mediated the relationship between NE and depressive symptoms for girls but not for boys. The results confirm and extend previous findings on the association between affective and cognitive vulnerability factors in predicting depressive symptoms and the gender difference in depression in adolescence, and suggest that clinical interventions designed to reduce negative emotionality may be useful supplements to traditional cognitive interventions for reducing cognitive vulnerability to depression.

The influence of child gender role and maternal feedback to child stress on the emergence of the gender difference in depressive rumination in adolescence.

Extensive research has linked a greater female tendency to ruminate about depressed feelings or mood to the gender difference in depression. However, the developmental origins of the gender difference in depressive rumination are not well understood. We hypothesized that girls and women may be more likely to ruminate because rumination represents a gender-stereotyped coping style that is associated with a more feminine gender role identity, maternal encouragement of emotion expression, and passive coping responses to stress. This study examined whether child self-reported gender role identity and observed maternal responses to child stress mediated the emergent gender difference in depressive rumination in adolescence. Maternal gender role attitudes were further hypothesized to moderate the relationship between child sex and mediating variables. Rumination and gender role identity were assessed in 316 youths and their mothers in a longitudinal study from age 11 to age 15; in addition, 153 mother-child dyads participated in an observational task at age 11 from which maternal responses to a child stressor were coded. Results indicated that greater feminine gender role identity among children and encouragement of emotion expression by mothers at age 11 significantly mediated the association between child sex and the development of depressive rumination at age 15, even after controlling for rumination at age 11. Maternal gender role attitudes significantly moderated the relationship between child sex and maternal encouragement of emotion expression, such that mothers who endorsed more traditional gender role attitudes themselves were particularly likely to encourage emotion expression in their daughters.

Stress and emotional reactivity as explanations for gender differences in adolescents' depressive symptoms.

In this longitudinal study, we examined whether certain types of stressful events and how individuals respond to these events would explain gender differences in depressive symptoms among adolescents. We hypothesized that certain stressful events would mediate the relationship between gender and depressive symptoms. We also hypothesized that individual differences in emotional reactivity would impact part of this relationship. Lastly, we examined whether gender differences in early childhood temperament might explain gender differences in emotional reactivity in adolescence. We examined these hypotheses in a sample of 315 adolescents (51% females; 93% Caucasian; 3% African-American; and 1% each Hispanic, Asian-American, and Native American) participating in a longitudinal study of child development since birth. We used multiple regression and constrained nonlinear regression to analyze the data. Results indicated that stressful events significantly mediated gender differences in depression, and that individual differences in emotional reactivity to these stressors significantly moderated the relationship between stress and depression. We also observed significant gender differences in emotional reactivity to these stressors; temperamental differences in withdrawal negativity in infancy were marginally significant in mediating gender differences in emotional reactivity to stress in adolescence.

The ABCs of depression: integrating affective, biological, and cognitive models to explain the emergence of the gender difference in depression.

In adulthood, twice as many women as men are depressed, a pattern that holds in most nations. In childhood, girls are no more depressed than boys, but more girls than boys are depressed by ages 13 to 15. Although many influences on this emergent gender difference in depression have been proposed, a truly integrated, developmental model is lacking. The authors propose a model that integrates affective (emotional reactivity), biological (genetic vulnerability, pubertal hormones, pubertal timing and development) and cognitive (cognitive style, objectified body consciousness, rumination) factors as vulnerabilities to depression that, in interaction with negative life events, heighten girls' rates of depression beginning in adolescence and account for the gender difference in depression.
