Evaluating interactions between emotion regulation strategies through the interpersonal context of female friends.

INTRODUCTION: There is a growing interest in examining how interpersonal relationships may shape associations between emotion regulation (ER) strategies and psychopathology. METHODS: We used multilevel modeling to test if respondents' self-reported intrapersonal ER, friends' self-reported intrapersonal ER, and their interaction were associated with psychopathology in a sample of 120 female friend dyads. RESULTS: Respondents' use of brooding rumination, expressive suppression, and worry were positively associated with respondent psychopathology. Friend reappraisal moderated the association between respondent reappraisal and respondent psychopathology. Consistent with an interference hypothesis, respondent cognitive reappraisal was only associated with respondent psychopathology when friend cognitive reappraisal was low. Consistent with a compensatory hypothesis, respondent reappraisal was primarily associated with respondent psychopathology when friend repetitive negative thought was high. DISCUSSION: Results support the extension of models of ER strategy interactions from intrapersonal to interpersonal contexts. Future research is needed to replicate the interference and compensatory interactions observed in the data.

Ethnic Differences in Resting Total Peripheral Resistance: A Systematic Review and Meta-Analysis.

OBJECTIVE: Decades of research suggest that there may be important ethnic differences in the hemodynamic mechanisms that co-determine arterial blood pressure, the primary diagnostic index of hypertension. In general, studies have observed that, compared with European Americans (EAs), African Americans (AAs) exhibit higher total peripheral resistance (TPR), an important summative index of peripheral vascular constriction. In contrast, EAs have been reliably shown to exhibit greater cardiac output (CO), which is directly linked to left ventricle and overall cardiac blood flow. We have previously proposed that elevated basal TPR, in particular, represents one component of the cardiovascular conundrum, characterized, paradoxically, by elevated resting heart rate variability among AAs relative to EAs. The present meta-analysis and systematic review of the literature sought to extend this previous work by establishing the magnitude of the empirically implied ethnic differences in resting TPR and CO. METHODS: A search of the literature yielded 140 abstracts on differences in TPR between AAs and EAs; 40 were included. Sample sizes, means, and standard deviations for baseline TPR with samples that included EAs and AAs were collected, and Hedges g was computed. RESULTS: Findings indicated that AAs had higher baseline TPR than did EAs (Hedges g = 0.307, SE = 0.043, confidence interval= 0.224 to 0.391, p < .001). In addition, EAs had higher resting CO than did AAs (Hedges g = -0.214, SE = 0.056, confidence interval = -0.324 to -0.104, p < .001). CONCLUSIONS: We discuss the present findings in the context of the role of elevated TPR in the deleterious effects of high blood pressure specifically for AAs.

Stereotype threat, trait perseveration, and vagal activity: evidence for mechanisms underpinning health disparities in Black Americans.

Objective: Black Americans (BAs) are at an elevated risk for morbidity and mortality in comparison to White Americans (WAs). Racial stressors are a common occurrence in American culture and is theorized to contribute to these disparities. When race-focused, stereotype threat (ST) is considered to be a factor that is detrimental to health in BAs; however few studies have directly investigated the impact of a ST manipulation on physiological function. Furthermore, it is proposed that racial stressors such as ST may have prolonged effects when more likely to perseverate (e.g. rumination) over the stressor and thus, those with greater trait perseveration may be more affected by ST. We sought to explore the impact of ST and trait perseveration on changes in vagus nerve activity - an indication of adaptive psychological and physiological well-being - as indexed by vagally mediated heart rate variability (vmHRV). Design: Forty-three (24 females, mean age of 20, standard deviation of 3 years) apparently healthy BA individuals were randomly assigned to one of three experimental conditions in which they received either implicit (subtle), explicit (blatant), or no ST priming (control condition), prior to completing a cognitive task. Resting vmHRV was assessed both at baseline (pre-task) and recovery (post-task). Results: BAs in the explicit ST condition exhibited the greatest decrease in vmHRV in comparison to the control group from pre- to post-task. BAs with moderate to high levels of trait perseveration showed the greatest decrease in vmHRV from pre- to post-task in comparison to those with lower levels of trait perseveration and BAs in the control group. Conclusion: These data suggest that racial ST, especially when explicit and coupled with trait perseveration, can decrease vagal activity, as indexed by decreased vmHRV, which when experienced frequently can have significant consequences for health and longevity in BAs.

From trust in caregivers' support to exploration: The role of openness to negative affect and self-regulation.

Attachment theory assumes that trust in caregivers' support and exploration are closely related. Little research tried to investigate this link, nor focuses on mechanisms that might explain this association. The present studies examined whether trust is related to exploration through a serial indirect effect of openness to negative affect and self-regulation. In Study 1, 212 children, aged 8-13, completed questionnaires assessing trust, openness to negative affect, self-regulation and exploration. The results showed that trust predicted exploration, but only to the extent to which openness to negative affect and self-regulation were involved too. Study 2 refined these findings (n = 59, aged 9-12) using a behavioral measure of openness to negative affect and exploration, and with mother-reported self-regulation. Replicating this serial indirect effect of openness to negative affect and self-regulation with multiple informants and methods, the present studies advance our understanding of how trust might foster exploration in preadolescence.

Quantifying respiratory sinus arrhythmia: Effects of misspecifying breathing frequencies across development.

Low resting respiratory sinus arrhythmia (RSA), and to a lesser extent excessive RSA reactivity to emotion evocation, are observed in many psychiatric disorders characterized by emotion dysregulation, including syndromes spanning the internalizing and externalizing spectra, and other conditions such as nonsuicidal self-injury. Nevertheless, some inconsistencies exist. For example, null outcomes in studies of RSA-emotion dysregulation relations are sometimes observed among younger participants. Such findings may derive from use of age inappropriate frequency bands in calculating RSA. We combine data from five published samples (N = 559) spanning ages 4 to 17 years, and reanalyze RSA data using age-appropriate respiratory frequencies. Misspecifying respiratory frequencies results in overestimates of resting RSA and underestimates of RSA reactivity, particularly among young children. Underestimates of developmental shifts in RSA and RSA reactivity from preschool to adolescence were also observed. Although correlational analyses revealed weak negative associations between resting RSA and aggression, those with clinical levels of externalizing exhibited lower resting RSA than their peers. No associations between RSA reactivity and externalizing were observed. Results confirm that age-corrected frequency bands should be used when estimating RSA, and that literature-wide overestimates of resting RSA, underestimates of RSA reactivity, and underestimates of developmental shifts in RSA and RSA reactivity may exist.

Understanding comorbidity among internalizing problems: Integrating latent structural models of psychopathology and risk mechanisms.

It is well known that comorbidity is the rule, not the exception, for categorically defined psychiatric disorders, and this is also the case for internalizing disorders of depression and anxiety. This theoretical review paper addresses the ubiquity of comorbidity among internalizing disorders. Our central thesis is that progress in understanding this co-occurrence can be made by employing latent dimensional structural models that organize psychopathology as well as vulnerabilities and risk mechanisms and by connecting the multiple levels of risk and psychopathology outcomes together. Different vulnerabilities and risk mechanisms are hypothesized to predict different levels of the structural model of psychopathology. We review the present state of knowledge based on concurrent and developmental sequential comorbidity patterns among common discrete psychiatric disorders in youth, and then we advocate for the use of more recent bifactor dimensional models of psychopathology (e.g., p factor; Caspi et al., 2014) that can help to explain the co-occurrence among internalizing symptoms. In support of this relatively novel conceptual perspective, we review six exemplar vulnerabilities and risk mechanisms, including executive function, information processing biases, cognitive vulnerabilities, positive and negative affectivity aspects of temperament, and autonomic dysregulation, along with the developmental occurrence of stressors in different domains, to show how these vulnerabilities can predict the general latent psychopathology factor, a unique latent internalizing dimension, as well as specific symptom syndrome manifestations.

Anxiety-related threat bias in recognition memory: the moderating effect of list composition and semantic-similarity effects.

Individuals with high anxiety show bias for threatening information, but it is unclear whether this bias affects memory. Recognition memory studies have shown biases for recognising and rejecting threatening items in anxiety, prompting the need to identify moderating factors of this effect. This study focuses on the role of semantic similarity: the use of many semantically related threatening words could increase familiarity for those items and obscure anxiety-related differences in memory. To test this, two recognition memory experiments varied the proportion of threatening words in lists to manipulate the semantic-similarity effects. When similarity effects were reduced, participants with high trait anxiety were biased to respond "new" to threatening words, whereas when similarity effects were strong there was no effect of anxiety on memory bias. Analysis of the data with the drift diffusion model showed that the bias was due to differences in processing of the threatening stimuli rather than a simple response bias. These data suggest that the semantic similarity of the threatening words significantly affects the presence or absence of anxiety-related threat bias in recognition memory. The results indicate that trait anxiety is associated with a bias to decide that threatening stimuli were not previously studied, but only when semantic-similarity effects are controlled. Implications for theories of anxiety and future studies in this domain are discussed.

Temperament and social behavior in pediatric brain tumor survivors and comparison peers.

OBJECTIVE: To examine the role of temperament (i.e., surgency/positive affect, negative affect, and effortful control) in the social behavior of pediatric brain tumor survivors and comparison classmates. METHODS: Parent-, peer-, and self-report data were collected for 75 children after treatment for a brain tumor, and 67 comparison classmates. Tests of mediation and moderated mediation were run to examine whether effortful control accounted for group differences in social behavior and whether this indirect effect was moderated by surgency/positive or negative affectivity. RESULTS: Peers described survivors as lower in Leadership-popularity and higher in Sensitivity-isolation and victimization than comparison classmates. Parent and self-report of surgency/positive affect revealed survivors were lower on this dimension. Survivors were rated by parents as demonstrating less effortful control. Effortful control did not consistently account for group differences in social behavior. There was limited evidence of moderated mediation. CONCLUSIONS: Research on the implications of potential changes in temperament following treatment is warranted.

Heart rate variability predicts control over memory retrieval.

Stopping retrieval of unwanted memories has been characterized as a process that requires inhibition. However, little research has examined the relationship between control over memory retrieval and individual differences in inhibitory control. Higher levels of resting heart rate variability (HRV) are associated with greater inhibitory control, as indicated by better performance on a number of cognitive, affective, and motor tasks. Therefore, we tested the hypothesis that higher levels of resting HRV predict enhanced memory inhibition as indexed by performance on the think/no-think task. Efforts to suppress no-think word pairs resulted in impaired recall for those items, as in past studies. Moreover, higher levels of resting HRV were associated with more successful suppression, as indicated by lower recall of the to-be-avoided stimuli relative to baseline stimuli. These findings are among the first to suggest that physiological markers of inhibitory control can be used to index a person's capacity to control unwanted memories.

Culturally compelled coping and depressive symptoms in Black Americans: Examining the role of psychophysiological regulatory capacity.

Given the culture of racism in the United States, Black Americans are often required to use culturally compelled coping (CCC) styles, such as emotional and behavioral restraint and vigilance. Although CCC is adaptive in the face of pervasive racialized stress, it may still negatively impact mental health outcomes, like depression. Studies have found that Black Americans exhibit higher resting heart rate variability (HRV)-a trait-level biomarker of self-regulatory capacity-than White Americans (Hill et al., 2015), which may reflect the additional resources that Black Americans need to regulate given experiences of racialized stress. Theoretically, this should protect against the development of mental health issues, like depression, given that lower resting HRV is typically observed in psychopathology (Beauchaine & Thayer, 2015). However, the literature is mixed on the buffering effects of greater resting HRV on psychopathology for Black Americans (Keen et al., 2015). Thus, we aimed to understand, with data collected from Black Americans between 2015 and 2018, how individual differences in resting HRV and the use of CCC, particularly restraint and vigilance, related to self-reported depressive symptoms. We found that at higher levels of resting HRV, greater use of CCC was associated with higher depressive symptoms. This suggests that CCC strategies may be detrimental to emotional well-being for those who have the capacity-as indexed by higher resting HRV-to engage in these strategies. Hence, the present study provides preliminary evidence that the ways Black Americans are often compelled to cope with racialized stress may be a path to greater depressive symptoms.

Attention Training as a Low-Intensity Treatment for Concerning Anxiety in Clinic-Referred Youth.

Although youth anxiety treatment research has focused largely on severe and impairing anxiety levels, even milder anxiety levels, including levels that do not meet full criteria for a diagnosis, can be impairing and cause for concern. There is a need to develop and test viable treatments for these concerning anxiety levels to improve functioning and reduce distress. We present findings from a randomized controlled efficacy trial of attention bias modification treatment (ABMT) and attention control training (ACT) for youths with concerning anxiety levels. Fifty-three clinic-referred youths (29 boys, M age = 9.3 years, SD age = 2.6) were randomized to either ABMT or ACT. ABMT and ACT consisted of attention-training trials in a dot-probe task presenting angry and neutral faces; probes appeared in the location of neutral faces in 100% of ABMT trials and 50% of ACT trials. Independent evaluators provided youth anxiety severity ratings; youths and parents provided youth anxiety severity and global impairment ratings; and youths completed measures of attention bias to threat and attention control at pretreatment, posttreatment, and 2-month follow-up. In both arms, anxiety severity and global impairment were significantly reduced at posttreatment and follow-up. At follow-up, anxiety severity and global impairment were significantly lower in ACT compared with ABMT. Attention control, but not attention bias to threat, was significantly improved at follow-up in both arms. Changes in attention control and attention focusing were significantly associated with changes in anxiety severity. Findings support the viability of attention training as a low-intensity treatment for youths with concerning anxiety levels, including levels that do not meet full criteria for a diagnosis. Superior anxiety reduction effects in ACT highlight the critical need for mechanistic research on attention training in this population.

Specificity of worry and rumination in the development of anxiety and depressive symptoms in children.

OBJECTIVES AND DESIGN. Rumination (specifically Brooding) is thought to be an important vulnerability factor for depressive symptoms whereas Worry is believed to be involved in anxiety. The present study sought to clarify the extent to which these two types of perseverative cognition show symptom specificity or generality in their associations with depression and anxiety. Additionally, reactive (negative affectivity, NA; positive affectivity, PA) and self-regulatory aspects of temperament (effortful control) were considered as vulnerability factors for depression and anxiety and were also studied in relation to rumination and worry. METHODS. Self-report questionnaires tapping Rumination, Worry, temperament, depression, and anxiety were administered to a community sample of 138 children aged 9-13. RESULTS. Brooding (but not Reflection) and Worry were significantly associated with anxiety and depressive symptoms on the one hand and with the temperamental construct of NA on the other hand. However, consistent with a model predicting symptom-specific relations, only Brooding significantly mediated the association between NA and depressive symptoms, whereas only Worry was a mediator of the relation between NA and anxiety symptoms. Finally, among self-regulatory aspects of temperament, activation control and inhibitory control were uniquely associated with depressive symptoms, whereas attentional control was only associated with anxiety symptoms. CONCLUSIONS. This study supports high NA as a vulnerability factor for the development of depressed and anxious symptoms in children, but these symptoms develop through differential paths.

Gender Matters: Nonlinear Relationships Between Heart Rate Variability and Depression and Positive Affect.

Vagally mediated heart rate variability (vmHRV), a measure of the parasympathetic nervous system's control over the heart, is often negatively related to maladaptive emotional outcomes. Recent work suggests that quadratic relationships involving these factors may be present; however, research has not investigated gender differences in these nonlinear functions. To address this gap, the current study tested for quadratic relationships between resting vmHRV and depression and positive affect while investigating gender differences in these relationships. Significant quadratic effects were found between resting vmHRV and reports of both depression symptoms and positive affect in women but not men. Specifically, the lowest levels of depression and the highest levels of positive affect were found at moderate vmHRV in women. These results suggest that examinations of vmHRV's nonlinear associations require the consideration of gender. Our findings are interpreted based on proposed differential neuropsychological mechanisms of vmHRV in men versus women.

Inhibitory control mediates the relationship between depressed mood and overgeneral memory recall in children.

It has been well established that depressed mood is related to overgeneral memory recall (OGM), which refers to a relative difficulty in retrieving specific information from one's autobiographical memory (AM). The present study examined whether OGM is also related to depressed mood in children and whether lack of inhibitory control mediates this relationship. One hundred thirty-five children (ages 9-13) completed measures assessing depressive symptoms, AM specificity, and inhibitory control. The results showed that depressed mood is positively associated with OGM and that inhibitory control mediated this relationship.

Heart Rate Variability Moderates the Association Between Beliefs About Worry and Generalized Anxiety Disorder Symptoms.

Paradoxically, some individuals who experience pathological worry also have good capacity for top-down control over their thoughts. Why such individuals would nevertheless worry excessively remains unclear. One explanation is suggested by research showing that those experiencing pathological worry are set apart from healthy controls by their beliefs that worry has utility and that effective worrying requires them to consider all possibilities before terminating a worry bout. This suggests that worriers with good capacity for cognitive control may engage in prolonged worry because they believe it is adaptive to do so. In a sample of 109 college students, among whom individuals reporting pathological worry were overrepresented, we tested this hypothesis using an objective index of top-down control capacity (i.e., resting vagally mediated heart rate variability [vmHRV]) and self-report measures of beliefs about worry and generalized anxiety disorder (GAD) symptom severity/status. As predicted, GAD symptom severity and vmHRV interacted to predict beliefs about worry. Specifically, high GAD symptoms were most strongly associated with beliefs that worry has utility at higher levels of vmHRV. Furthermore, this pattern was mostly a function of the belief that worry serves to distract the worrier from more emotional things. Similarly, high GAD symptoms were most strongly associated with endorsement of an 'as many as can' (AMAC) problem-solving rule when vmHRV was high. From the opposite perspective, both worry utility beliefs and AMAC rule endorsement were associated with the highest GAD symptom severity at higher levels of vmHRV. This was also true for the belief that worry distracts from more emotional things predicting analog GAD status. These results suggest that worriers who have higher levels of top-down control capacity may initiate and persist in worry, at least initially, because they value it. However, why they nevertheless rate their worry as excessive and uncontrollable is an important question for future research.

A Randomized Controlled Trial of Attention Bias Modification Treatment in Youth With Treatment-Resistant Anxiety Disorders.

OBJECTIVE: Randomized clinical trials of augmentation strategies for youth with treatment-resistant anxiety disorders do not exist. This report presents findings from an efficacy trial of attention bias modification treatment (ABMT) as an augment for this population compared with attention control training (ACT). METHOD: Sixty-four youths (34 boys; mean age 11.7 years) who continued to meet for anxiety diagnoses after completing cognitive-behavioral therapy were randomized to ABMT or ACT. ABMT and ACT consisted of dot-probe attention training trials presenting angry and neutral faces; probes appeared in the location of neutral faces on 100% of trials in ABMT and 50% of trials in ACT. Independent evaluators, youths, and parents completed ratings of youth anxiety severity, and youths completed measures of attention bias to threat and attention control at pretreatment, post-treatment, and 2-month follow-up. RESULTS: The 2 arms showed significant decreases in anxiety severity, with no differences between arms. Specifically, across informants, anxiety severity was significantly decreased at post-treatment and decreases were maintained at follow-up. Primary anxiety disorder diagnostic recovery combined across arms was 50% at post-treatment and 58% at follow-up. Attention control, but not attention bias to threat, was significantly improved at post-treatment in the 2 arms. CONCLUSION: This is the first study to show anxiety can be decreased in youth who did not respond to cognitive-behaviorial therapy, and that the anxiety-decreasing effect is found using these 2 attention training contingency schedules. These findings and increases in attention control in the 2 arms raise intriguing questions about mechanisms of decreasing anxiety in treatment-resistant youth with attention training that require further research.

Attentional retraining: a randomized clinical trial for pathological worry.

OBJECTIVE: Research has consistently shown that highly anxious individuals tend to show an attentional bias in favor of threat cues (i.e., a threat bias). Further, recent evidence suggests that it is possible to modify patterns of attention allocation for such stimuli and the resulting changes in attention allocation alter affective responses to stress. However, to date such changes in patterns of attention have been shown only over brief time intervals and only in non-anxious individuals who lack a pre-existing attentional bias. In contrast, the present study tested the efficacy of such attentional training in a sample of severe worriers over an extended period of time using psychometrically validated measures of anxiety and depression. METHOD: Twenty-four adult participants reporting severe worry were randomly assigned to receive five sessions of either computer-delivered attentional retraining or sham training. The study was conducted from January to August 2001 and June to August 2002. RESULTS: Significant Treatment Group X Time interactions were found for both threat bias (p=001) and a composite measure of anxious and depressive symptoms (p=.002). Compared to sham-training, the active retraining program produced significant reductions in both threat bias and symptoms. CONCLUSIONS: These data support the view that an attentional bias in favor of threat cues is an important causal factor in generalized anxiety and suggest that a computer-based attentional retraining procedure may be an effective component of treatment.

Party Pooper or Life of the Party: Dampening and Enhancing of Positive Affect in a Peer Context.

Dampening and enhancing responses to positive affect have been linked to depressive symptoms. The main aim of the present study was to examine such responses in an interpersonal peer context and to examine their relation with depressive symptoms. A community sample of 665 seventh-graders (52.0% girls, Mage = 12.7 years) took part in the study. Using a newly developed questionnaire, the Co-Dampening and Co-Enhancing Questionnaire (CoDEQ), a two-factor model distinguishing co-dampening and co-enhancing was validated. Relations with general depressive symptoms, anhedonic symptoms, and friendship quality were investigated. The direction of relations was examined over a 1-year interval using cross-lagged analyses. Cross-sectional results revealed that higher levels of co-dampening and lower levels of co-enhancing were associated with more depressive and anhedonic symptoms, while controlling for co-rumination levels. For anhedonic symptoms, this pattern also held over and above intrapersonal dampening and enhancing. Friendship quality was related to higher concurrent levels of co-enhancing and lower levels of co-dampening. The longitudinal results pointed towards a scar model, in that both depressive and anhedonic symptoms predicted relative increases in co-dampening over time; however, this did not hold in a model in which dampening and enhancing were included as control variables.

Anxiety Sensitivity Amelioration Training (ASAT): a longitudinal primary prevention program targeting cognitive vulnerability.

Fear of arousal symptoms, often referred to as anxiety sensitivity (AS) appears to be associated with risk for anxiety pathology and other Axis I conditions. Findings from a longitudinal prevention program targeting AS are reported. Participants (n=404) scoring high on the Anxiety Sensitivity Index (ASI) were randomly assigned to receive a brief intervention designed to reduce AS (Anxiety Sensitivity Amelioration Training (ASAT)) or a control condition. Participants were followed for up to 24 months. Findings indicate that ASAT produced greater reductions in ASI levels compared with the control condition. Moreover, reductions were specific to anxiety sensitivity relative to related cognitive risk factors for anxiety. ASAT also produced decreased subjective fear responding to a 20% CO(2) challenge delivered postintervention. Data from the follow-up period show a lower incidence of Axis I diagnoses in the treated condition though the overall group difference was not statistically different at all follow-up intervals. Overall, findings are promising for the preventative efficacy of a brief, computer-based intervention designed to decrease anxiety sensitivity.

Negativity bias in attitude learning: a possible indicator of vulnerability to emotional disorders?

Negativity biases, i.e., tendencies for negative features and interpretations to predominate over positive, are known to play a role in the etiology and maintenance of emotional disorders. Both depression and anxiety have been associated with such negative cognitive styles. Recently, Fazio, R.H., Eiser, J.R., and Shook, N.J. [(2004). Attitude formation through exploration: Valence asymmetries. Journal of Personality and Social Psychology, 87, 293-311] have observed similar valence asymmetries in the domain of attitude formation and generalization. The present research examined the possibility that the extent to which individuals display a learning bias in attitude formation is related to negative cognitive style and emotional disorder symptoms. Participants played a computer game that required learning whether novel stimuli produced positive or negative outcomes. Poorer learning was associated with more negative cognitive style, greater depression, and a tendency toward greater anxiety. Interestingly, these relations were most evident with respect to the learning of the positive stimuli, suggesting that an under-appreciation of positive objects and events may underlie vulnerability to emotional disorders. The potential value of various indices of negativity bias that can be assessed when examining attitude formation and generalization is discussed.
